The electric motor drives the worm reducer, which rotates the satelite. and the shaft changes the angle of rotation during rotation. Due to their design, worm gear motors are characterized by smooth and quiet operation. The essence of the worm mechanism brakes the rotation. The worm gear motor can be equipped with one or more mechanical planetary gears. Below we will look at how you can make a simple reducer with your own hands.

As a rule, a good home workshop has many devices and fixtures, with the help of which you can facilitate manual work and increase the efficiency of your work. For example, these include reduction gears.

One of the main and critical parts of the reduction reducer is its housing. The shafts and axles of the reducer serve as a support for the gears. As a rule, only shafts with rigid pinion mounting (tight fit, key or splines) are used in a single-stage gearbox.

The axle is used when we need to insert an intermediate pinion into the gearbox (for example, to ensure that the input and output shafts rotate in the same direction). Bearings in the reducer serve as supports for the shafts and absorb loads that occur during the operation of the reducer.

No less important parts of the gearbox are gears. It is the geometrical dimensions of the gears and their ratio that will determine the axial distance between the gearbox shafts and the layout of the gearbox housing. During the installation of gears, it is important to correctly set the gap between them, as the loading capacity and noise level during the operation of the gearbox depends on it.

How to repair a motoblock gearbox by yourself?

The material set out in this article is particularly popular with people who repair their machinery on their own. The following will touch on the main “subtleties” relating to the repair of the gearbox of a power tiller. To go directly to the topic of repair, it is necessary to understand the structure of the gearbox. Looking ahead it should be said: the structure of the reducers of modern power tillers is similar between themselves, there are only minor differences in one model or another.

To avoid the question “How to disassemble your motoblock gearbox?”, you need to be familiar with all the details. Let’s list the main parts and components of any modern motoblock: covers and pulley; bushings with bearings; lever, axle and fork for shifting; primary shaft block with pinion; input and output shaft of the motoblock reducer. Accessories: washers and oil seals; right and left half-axle; clutch and clutch fork; bracket and spring.

What kind of gearboxes for a power tiller

All of them find their application on power tillers of different types.

Corner

Angular gearbox for a power tiller provides a connection of engine with transmission and hitch. Other attachments are also used, if you modify it. The angular device consists of the following parts:

• flange;
• flange mounting;
• bearing;
• housing;
• pulley;
• belt;
• A washer made of steel;
• pulley mounting;
• dowel;
• rotary shaft.

This device can be made by yourself. Before working, you need to consider the conditions in which it will have to work. This is the radial and axial load at the ends of the shafts. The load depends on the type of lubricants and temperature. It is best to choose a factory-made housing. The correct size bearings are selected for the shaft.

Reducing

Reducing gearbox for a power tiller, self-made or industrially made, is designed to increase the power of the agricultural machine. You may need this when the tiller is operating on sandy ground, when the wheels start to slip. It is used on gasoline and diesel vehicles equipped with air cooling system.

Reducing the number of revolutions and increasing the power of the drive mechanism can be achieved by using reduction gears, sometimes called a stroke-reducers for power tillers. They are most reliable for air-cooled diesel or gasoline tractors. The number of revolutions is reduced while the machine is in operation. This allows the single-axle tractor to be used for particularly heavy work, such as plowing heavy soil or harvesting potatoes with a potato digger.

Gearbox

The differential gear converter is used in heavy-duty tractors. It fits well with engines that have a vertical crankshaft. Gearboxes make little noise at work and are very quiet and powerful. Can work in forward and angular rotation. Both conical and spur gears are used. Requires oil in the crankcase at all times, but this is compensated for by its high power.

On heavy machines, the gear converter is often equipped with a gear box. This transmission enables the tractor to move in reverse. Reverse occurs during reverse rotation of the gears in the housing. This is achieved by changing the position of the lever on the outside of the housing.

The gear reducer is the best choice for heavy farm machinery. Engine with this mechanism lasts longer than with the worm type.

Worm gear

The worm gearbox is widely used to equip minitractors and power tillers. Long trouble-free life and high reliability have made this model popular. The worm-type unit is reversible, allowing the machine to move in reverse. The distinctive feature of this converter is the presence of a special screw and worm wheel. Profile of thread on the parts. trapezoidal. They are made of high-strength materials.

The screw can be four threaded or two threaded. It matches the thread on the sprocket. The teeth on quality parts are made of antifriction steel. The efficiency of the device is high. Its advantages:

• The gearbox allows you to extend the life of the motor;
• Creates little operating noise
• The device consists of only 2 parts;
• has a high gear ratio;
• has smooth running;
• High self-braking effect.

All positive features appear when the mechanism is precisely assembled and adjusted.

Chain

The chain device in its design necessarily has a chain. Sometimes there is more than one chain. The gear chain slips over the sprockets and allows them to turn. The device is easy to operate, has reverse function and high degree of reliability. The operating principle is similar to the belt mechanism. It is easy to change the gear ratio by changing the sprocket size. They work like a bicycle, but in reverse: the small one is the drive sprocket and the big one is the sprocket wheel.

Reliable operation is ensured by quality sprocket metal and chain strength. If you make your own gearbox, you should take motorcycle sprockets, they are much stronger than bicycle sprockets. Product structure is simple and reliable, has reverse. Chain requires regular lubrication and tightening. Its rupture is a common cause of gearbox failure. Need to change chain for repair.

Combination

Combination gears combine gears and worm, worm and spur gears. It can be a single-stage or multistage gearbox. The single-speed has a gear ratio of up to 7. Body made of cast iron or welded aluminum. Two-stage units have gear ratios up to 40, three-stage units up to 150.

All of them are designed to change speeds on the engine and PTO shafts. All types of gears are housed in a single housing. The combined mechanism is the most practical. With small dimensions it has high qualities and low cost.

Types of gearbox units

Transmission of rotary motion from the motor shaft to the shaft of the actuator can be made by direct connection of axes, if the speed and power of rotation of the motor is acceptable for work, and the axes of the drive and driven shafts coincide. Such cases are extremely rare, and with several attachments for different purposes, direct drives are absolutely impossible. 4 types and combinations of mechanisms are used to match the speed and power of the drive and driven shafts. Basic types of gears:

The worm gear is structurally limited to the reduction function, the others can be used in both reduction gears and up gears. In addition, such a gearbox always has a driven axis perpendicular to the shaft of the driving. This type of gearbox is called an angular gearbox. In addition to the worm gear, you can change the axis direction with a spatial planetary mechanism. Belt and chain drives leave the driven axle parallel to the motor axle. In simple devices, reversing is only possible by changing the rotation of the motor.

Motor blocks use engines with a high number of revolutions per minute, as you can verify in the product data sheet. So, with your own hands you need to make a reducer to reduce the speed, and what type will be a homemade reducer on a single axle tractor, it is better to choose, knowing the characteristics of each type.

Belt drive

Every motorist who has ever looked under the hood is familiar with a pulley or belt that transmits rotation from shaft to shaft. RPM reduction factor is determined by dividing the small driven wheel radius by the large driven wheel radius.

Pros to the belt reducers. it is easy to make and repair, a large variety of parts. And the disadvantages of the belt:

• Belt stretching, decreasing grip on the pulley from temperature and wear;
• slipping when torque is increased sharply
• short service life.

compensate for the shortcomings of the spring-loaded roller, pressing on the belt surface between the wheels, the application of the toothed belt on pulleys with cross chamfers. Belt drives require the drive and idler pulleys to be in the same plane; bending or twisting the belt will quickly cause it to break.

Chain type

The chain drive principle is similar to the belt drive, but instead of the pulleys there are sprockets, and the belt is replaced by a chain. Such a homemade gearbox will not allow slipping, and in similar conditions will work much longer. Just like the belt, the chain reducer must have the leading and driven sprockets in the same plane, and its gear ratio is calculated by the ratio of their teeth. This design weighs more than a belt drive, but is more reliable on heavy-duty blocks.

Unlike belt drive, chain drive requires caution or extra safety precautions. If a rotating tool collides with a thick root in the ground, its drag force will be transmitted to the engine, which can damage it. Unless the engine fails or shuts down, it will try, with maximum power, to revolve with the frame around the gearbox idler axle. The more horsepower the engine has, the greater the overturning torque.

The gear ratio of a chain reducer may be higher than that of a belt reducer of the same size, since the drive sprocket, even though it is small, will not allow the chain to slip.

In terms of cost, ease of assembly, the prevalence of parts chain transmission is not inferior to the belt.

With pinions

A single-axle tractor with a gear reducer is more reliable, durable than a chain or belt reducer. Gear designs are put on factory products, and not only on motor blocks. The assemblies turn out small-sized as a result of combining two gears with different diameters on one axis. For example, a reducer from a scooter Muravey would be perfect for a motor-block. But you can make your own, using gears from motor vehicle gearboxes. The required reduction ratio can be provided by a planetary mechanism, in which satellite gears mounted on a stationary ring, the driver, are installed between the external and the sun gears:

For a reduction gear, the sun gear is mounted on the drive shaft. The planet gear wheel with planetary gears is fixed on the stationary body, and the outer gear is connected to the actuator, rotating in the opposite direction to the sun gear.

Gear ratio of such a reducer can be calculated as a ratio of number of teeth of sun gears to the number of teeth on the external gear.

To change the direction of the axis of rotation, gearboxes use a spatial planetary mechanism in which the gears must be tapered at 45 degrees each to change direction by 90 degrees. The diameter of the gears can be different, which can be used to change the gear ratio.

For a motor-block such an angular gearbox with their own hands is not often made, because the planetary gears of the required size are still to be found. Changing the axis of rotation is often done by factory-fabricated gears or worm gears.

Worm gear

For a perpendicular change in the direction of the axis of rotation, creating a large transmission ratio, the contact of a flat gear with an Archimedean screw is used. Rotation cannot be transferred from an actuator to a motor. This is a unique feature of worm gears, other types of gears do not have this property. The output speed can be reduced by as many times the number of teeth. This gear is distinguished by simplicity of assembly, high friction, small size, great popularity.

How to control the speed?

Sometimes it happens that you want to change the speed of your power tiller: increase it or, which happens quite rarely, decrease it.

One of the following two methods is usually used to increase the speed of motor-block units:

The normal wheel diameter of almost all power tillers is 570 mm. Most often, the replacement is for a tire with a diameter roughly 1.25 times larger than the given one. 704 mm. Even though the difference in size is relatively small (only 13.4 cm), the speed increases significantly. Of course, if your design allows for larger tires, you can try to increase the speed gain.

The gear train set in the wheel gearbox usually consists of two pinions with 12 teeth in the small one and 61 in the big one. You can change this figure to 18 and 55 respectively (only by specialists in agricultural machinery service centers), then the gain in speed will be about 1.7 times. Do not try to change the gears yourself: it is very important not only to pick up quality parts with a minimum of error, but also an appropriate pulley. The gearbox-shaft retainer plate also plays an important role.

Logically speaking, a decrease in speed can be achieved by diametrically opposite steps. to reduce the tire diameter or the number of teeth on a pair of gears.

A possible solution to increase the speed is also to adjust the gas switch: when you turn on the machine, move it from the first position to the second. To reduce the speed, return to the original position. Of course, to change the speed downward you do not need a special reducing gear. it is enough not to switch to high gears.

Other possible solutions to the problem of increasing the speed of a power tiller can be replacement of the engine for a more powerful one and modernization or installation of a clutch system (some old models do not have it).

Installation of weights can also help to increase speed (especially on uneven terrain or heavy soils, where slippage is more common because of the insufficient weight of the machine). These can also be made from metal parts of your own making. The weighting structures are installed on the frame of the power tiller and the wheels. For the frame you will need metal corners, which form a makeshift removable structure, that is, you can easily remove it in case of lack of need. Additional ballast weights are attached to this removable additional frame. Wheels need steel disks and solid iron pins with a hexagonal cross-section. These parts are welded together and inserted into the hubs. For reliable fixation the cotter pins are used which are inserted into the specially prepared holes.

Of course, if you have no round steel elements at hand, you can replace them with almost any improvised material: articles of reinforced concrete or even compacted round plastic flasks, which are filled with sand inside.

Do not forget about the balance: the weights on the wheels should be equal in weight, and on the frame. evenly distributed, otherwise there will be a misalignment, due to which when performing turning maneuvers your machine can fall on its side.

To accelerate a motor block with a cart in bad weather conditions. snow, slush, muddy soil from heavy rains. you can put tracks (if the design allows it). This method requires an additional set of wheels and the purchase of caterpillars made of rubber of a fairly large width. Rubber stops are attached on the inside of the track to secure the rubber and prevent it from coming off the wheelset.

Varieties of travel reducers for motor vehicles

Gear reducers for motorcycles have different structures and working principles. Consequently, any of such mechanisms has different parameters, advantages and imperfections.

According to such indicators available on the market reduction gearboxes for motorcycles are divided into several types.

• Gear reduction gears are particularly rugged machines. The steel from which the gears are made is coated with specialized protective agents, which greatly increases the stability and lengthens the period of use of the gears. One of the disadvantages of this type of devices is a high price.
• Reducing worm gears. such a device is used in motors with vertical shafts. The worm gearbox for the machine is mainly designed for plowing previously cultivated soil. The use of worm gears on uncultivated land leads to its inevitable failure.
• Chain variators. this kind of equipment has long service life and affordable price. The shell of the device can be demountable and non-dismountable. The first model is much more practical, because if a unit with a collapsible shell breaks down, it can always be repaired by one’s own efforts.
• Combined (pinion and chain) gearboxes. this kind of attachment is the most suitable solution for tractor equipment. They are characterized by their low price, long service life and excellent resistance to high loads.

Each reduction gearbox has its own way of behaving under the various conditions of use. It is necessary not to forget about it when choosing a certain device for motorcycles.

Variety of Stroke Reducers for Motorcycles

Gear reducers for motorcycles with different structures and working principles. Consequently, any of such mechanisms has different parameters, advantages and imperfections.

In these respects the reducers for motorcycles available on the market are divided into several types.

• Gear reduction gears. this equipment has a particularly robust design. Steel, of which the gears are made, is coated with specialized protective substances that significantly increases resistance and extends the period of exploitation of the reducers. Among the disadvantages of this type of devices it is necessary to make an accent on the high price.
• Reducing worm gears. such a device is used in motor vehicles with vertical shafts. Worm walker for the machine is designed primarily for plowing previously cultivated soil. Using a worm reduction gear on uncultivated land leads to its inevitable failure.
• Chain walkers. this kind of equipment has a long service life and affordable price. The outer casing of the implement can be either demountable or non-dismountable. The first example is much more practical because if a demountable casing unit fails, it can in any case be repaired by oneself.
• Combined (pinion-chained) gearboxes. devices of this type are the most suitable solution for tractor equipment. They are low in cost, have a long service life and stand up very well to high loads.

Any step-down reducer in its own way behaves in different conditions of use. It is important not to forget about it when selecting a specific device for your motorcycle.

Making it with our own hands

How to make a single axle tractor with your own hands? The design of the mechanism is very similar to the gearbox. With its power steering feature, it distributes some of the tractive power to additional attachments. The work on the manufacture of the device can be divided into several stages:

• Preparatory measures. At this stage, the case for the future mechanism is selected, metal pipes, bearings, gears, steel sheet and screws are prepared.
• the shafts are made. The basic material is hardened round steel. Using machines, workpieces are turned over to achieve the exact size and grooves are created. The shafts transmit the torque, and the radial bearings hold them.
• Install the chains and sprockets. This material is better to buy in the store.
• After assembling the housing of the stroke limiter, it is tested. If there is any extraneous noise and squeaks, stop and correct the damage.

Tip. You should only take up the manufacture of self-made devices if you have experience and strictly follow the algorithm of necessary operations during assembly.

How to make a single axle tractor with your own hands? The design of the mechanism is very similar to a gearbox. Including it in the work of the power tiller redistributes part of the traction force on additional attachments. The work on the manufacture of the device can be divided into several stages:

• Preparatory steps. At this stage, the case for the future mechanism is selected, metal pipes, bearings, gears, steel sheet and screws are prepared.
• Shafts are made. The basic material is round rolled hardened steel. Using machines, workpieces are ground to the exact size, and grooves are cut. The shafts transmit the torque, and the radial bearings hold them.
• Install chains and sprockets. It is better to buy this material in a store.
• After the housing is assembled the unit is subjected to a test run. If any unusual sounds or squeaks occur, stop and correct the irregularities.

Advice. Take up the manufacture of homemade devices should only be undertaken if you have experience and when assembling clearly adhere to the algorithm of necessary operations.

Materials and tools required

A variator is a regular reduction gear that increases torque by reducing engine speed. There are different types of gearboxes, for the motor-block the gearbox is the most applicable.

To assemble a reduction gear reducer you will need:

• measuring and drawing devices for creating a drawing;
• metal saw;
• drill with drills;
• bearings;
• pulley;
• steel sheet with a thickness of 3-4 mm (CT3 steel will do);
• ready-made casing (from a generator);
• Bevel drive and ordinary idler gears;
• driven shaft and rotor shaft.

Various bolts, nuts and washers will be needed for mounting. In some cases, it is advisable to use a welding machine.

Stroker

Grip of the wheels of the tillage machine with the soil can be strengthened by the use of grousers or walk-reducer for the power tiller. The reduction gear reducer is one of the attached devices. It makes it possible to reduce the speed of the agricultural machine and increase traction along with the torque. The analogue of the gearbox works with a chain and sprockets on the shafts. If you want, you can make this fixture yourself. Parts are used from other equipment.

Each of the considered transducers has its own disadvantages. To keep their number to a minimum, it is worth trying to make the device yourself. A self-made thing can be of higher quality and more convenient to use than a purchased copy.

The primary shaft sprockets are mounted first. If the construction is massive, the flange or keyway attachment is secured by means of spot welding. In the next stage, choose the method of attachment of the drive shaft and a pair of half axles.

When mounting, you should consider the possibility of a star shift in one of the two directions. The body is made by yourself or have it made by a specialist. If the first option is chosen, consider the features of the glands, the corresponding seals and bearings.

How to make a reducer on a single axle tractor with their own hands

Homemade gearbox for power tiller requires the preparation of tools for making. For a fruitful work will be needed:

• screwdrivers of various sizes;
• hacksaw for metal;
• pliers;
• Locksmith’s vise;
• welding machine;
• Hammers of different weight;
• rubber for gaskets;
• drill with drills.

In the process of work, some other tools may be required. Materials to be prepared include shafts and bearings, sprockets and chains, belts and gears. You can use a caliper to measure parts. Before working, the simplest drawings should be made.

Preparing

So, the tools and sketches are ready, you need to prepare the material for welding the body or take ready-made. It can be welded from pieces of stainless steel. The prepared gears must fit freely into the ready-made housing. They can be borrowed from an old chainsaw. Druzhba or any other brand is suitable. The saw must be carefully disassembled and the whole gears together with the shafts must be taken out. They are cleaned and washed, then sized to match the gear ratio.

When calculating the gear ratio, you should take as a basis the number of idle engine crankshaft speeds and add 10% to them.

With any design of the product, do not allow for misalignment between the parts of the driven and driven parts.

Do not replace the bearings with bushings either. When disassembling an old saw keep this in mind.

Assembling

When assembling the product parts are carefully inserted into their places in the body and rotated. The housing must be hermetically sealed. This will prevent dust and dirt from getting on the parts. Glands are installed on the shafts. Grease is poured inside the housing. Connects the homemade device in the same way as the regular reducer. To test it, the engine is started and rolled on the ground. Parts should work a little on each other.

So, the tools and sketches are ready, you need to prepare the material for welding the body or take ready-made. Can be welded from pieces of stainless steel. The prepared gears should fit freely into the ready-made housing. These can be borrowed from an old chain saw. Druzhba or any other brand is suitable. The saw must be carefully disassembled and the whole gears together with the shafts must be pulled out. They are cleaned and washed, then matched in size according to the gear ratio.

When calculating the transmission ratio you should take the number of idle engine crankshaft speeds as a basis and add 10% to them.

With any design of the product, there must be no misalignment between the parts of the driven part and the driven part.

Bearings must not be replaced by sleeves either. When disassembling the old saw it must be remembered.

Assembling

When assembling the product the parts are carefully placed in their places in the body and turned. The body must be sealed hermetically. This prevents dust and dirt from getting onto the components. Oil seals are installed on the shafts. The inside of the housing is filled with a lubricant. The homemade device is connected in the same way as the original gearbox. To test it, start the engine and run it on the ground. The parts need to work a little on each other.

Additional attachments

The machine is sold with a minimum number of parts. But a tiller and a standard plough are not enough for all farm work. How to improve a power tiller with improvised materials? Every home tool can be used to broaden the possibilities of your power tiller. Equipment that you can make yourself:

• Mounting a rake on a single-axle tractor to pick up trash, leaves, or hay. Such a simple device will accelerate autumn field work, allowing you to clean large areas from debris in minutes. To make the rake you will need: several meters of rebar with a section of 8-12 mm and a strip of sheet metal. Fittings are cut into 10 cm long pieces and welded to the plate in several rows, with a gap of 3-5 cm. To increase maneuverability you can equip the rake with roller wheels.
• Trailer and wagon to help haul bulky loads. The cart can be made from improvised materials. channel bars and old car wheels, metal profiles and boards. Clutch is made as standard for tractors and cars.

Plows for power tillers

Another attachment for tillage with a power tiller is a plow. The types of plows are distinguished:

• The easiest to use is a single-hoe plow, also known as a Zykov plow.
• Reversible plow for power tiller: rotary or reversible. Top with a curved ploughing feather that turns the soil while ploughing. A universal device that easily copes with plowing heavy soils. Quickly manages to work areas with clayey and swampy soils.
• Rotary plow for power tiller has a complex design. Depending on the number of shares, there are double and triple share models. Active coulters only tip to one side while passive coulters compare and lift the beds. Advantages of ploughing with this plough include maximum oxygenation of soil, lower tire and fuel consumption, and no large clods of soil remaining after ploughing.
• A rotary plow for a power tiller gives unlimited possibilities. axle swivels during work, so do the soil layers. Plows even very hard terrain easily to a depth of about 30 cm. A distinction is made between trailing, trommel, shovel and auger plows. The first type is equipped with a rigid pusher, can consist of a spring plate or be combined. The second type of unit is equipped with a disc with blades that rotate during work. A plow with a disk blade for a power tiller is suitable for work in early spring, it copes well with wet soil.

Gear walker by own forces

For constructive activities, you will need:

• screwdrivers of different sizes;
• hacksaw for iron;
• pliers;
• iron vice;
• Welding machine;
• hammers of various weights;
• rubber for gaskets;
• power drill and drills.

Preparatory work

If the tools and drawings are ready, it is necessary to prepare the material for welding the body or take ready-made. They can be made out of stainless steel. The prepared housing must fit the prepared gears without hindrance. They can be taken from an old petrol saw. Suitable brand “Druzhba” or any other. The saw must be carefully disassembled and the undamaged gears, along with the shafts, must be taken out. They are cleaned and washed, then sized according to the gear ratio. When calculating the ratio, take the number of idle engine crankshaft rotation as a base and add 10% to it.

Self-assembly of the stroke reducer

Having all the necessary spare parts, you can proceed to the assembly of the stroke reducer with your own hands. In order for the finished construction to cope well with its functions, you should act clearly according to the algorithm described below:

• First make all the necessary calculations, so that the result of the work is a well-balanced design. As an alternator, you can take an element from a domestic motorcycle “Ural”;
• The main thing that is required from the device. high power and stable torque;
• Next, proceed to cut the shell of the two bearings that will be needed for the drive shaft. It will run the gear. Consider the diameter of the gearbox when working;
• Then determine the bearings. The flange must be on the opposite side of the gearbox. There should be a metal washer inside it;
• Next, install the drive shaft, which will be the pinion. The product should be connected to the shaft of the rotary generator and the transmission mechanism;
• At the end, it is necessary to fix the pulley with the drive shaft by means of a spring nut and a washer.

Making a walker, it will be necessary to test. To test the device, it should be connected to the coupling of the machine, as well as set the wheels for the cultivator. If you have done everything correctly, the wheels will turn slowly, while the cultivator itself will be pressed to the ground.

Choosing wheels for a rotary cultivator, which will work together with a stroke reducer, it is necessary to pay great attention to their diameter. It is not necessary to choose too large parts, so as not to load the machine’s motor. Wheels with a diameter of 25 to 30 cm will be optimal.
