Reducing gearbox with own hands: description, diagrams, drawing and feedback

A reducing gear is a device that is designed to convert torque. Allocate worm, planetary and combined modifications. The motor with the gearbox is capable of operating at high revs. The standard model consists of a shaft, pushers and gears. If necessary, a down-type device can be made independently.

Schematic of worm modification

Scheme worm mechanism includes a wide disk, next to which is the gear. The first pusher is located at the bottom of the reducer. In this case, the coupling is fixed in the front part of the housing. To make the device yourself, first of all the stand for the shaft is cut out. Next, you need to fix the disks. The fixator is soldered last.

Assembling a planetary device

This reduction gearbox for the electric motor is different in that it uses a two-chamber box. The pushers of the modifications are of different sizes. To make a device yourself, a wide block is prepared. Further it is important to install the pushers. The clutch itself is fixed directly to the clamping spring.

Specialists recommend in advance to grind the rack and weld on it supports. The gear is locked in the rear of the gearbox. The pressure plate is installed only with the stop. Lockers can be mounted with a roller mechanism. Also it should be noted that there are a lot of self-made modifications with additional stops that stabilize the shaft.

Cylindrical gearboxes

Recently, a cylindrical self-made reduction gearbox has been actively used. With your hands, the device can be made with a short and long shaft. In this case, the stops are installed in the rear of the case. Some devices are assembled with one gear. Before starting the installation of the part, a block for disks is prepared. The gearbox shaft is fixed to the rack.

The holder is allowed to do with the stop. Ball bearings are fixed at the base of the shaft. Pressure plates for models can be of different sizes. If we consider compact devices, the spring should be set to a small diameter. Also it should be noted that the gears fit behind the shaft. The pushers must not touch the disc. The cover is screwed in the front part of the case.

Conical model drawings

This reducing gear can be made with longitudinal pushers. Discs are most often installed on a short rack. To switch the clutch is set lever. Many modifications are collected with an adapter holder. The shaft is fixed behind the counter. To adjust the tension, a coupling is used. At the end of the job, you will only have to secure the lid. The motor with a reduction gear is capable of operating at a frequency of 50 Hz.

Feedback on combined devices

Combined reducers, reducing the speed, among professionals are highly appreciated. If you believe the reviews, then the models are well suited for asynchronous motors. The pushers are more appropriately used from steel plates. To install the discs are used stops. The coupling at the modifications is fixed behind the shaft. If you believe the experts' opinions, then the clip can be cut out from a regular plate. It should also be noted that the lid is more suitable to install with a screw clamp.

Modifications with one clamp

Making a reduction gearbox by one's own hands is very simple. The pushers in this case must be installed under the stops. A box for modification can be selected from a single-chamber type. Gears are allowed to be used with a clamp. The pressure plates are fitted with a roller mechanism. The pressure plate is fixed in front of the pusher. To install the spring, use a hammer. Clutch for clutch is attached under the disk. Ball bearings are allowed to use different sizes.

Devices for two latches

Modifications to the two latches are added together with a dual camera. In total, two disks are required for the assembly. Directly the coupling is selected with a support spring. Many experts say that the pushers are more appropriate to use the U-shape. A gear lever is used to change gears. If you believe the reviews of specialists, then the gears must be stuffed for a very long time. In this case, it is important to fix the shaft at the base of the chamber. At the end of the work, it remains only to make the holder for the rollers.

Models with a front position of pushers

Reducing gears for motoblocks with the front location of the pushers are able to maintain high speeds of the induction motor. The holders of the modifications are installed with roller mechanisms. Many models are added with longitudinal stops. Before the assembly begins, the camera is prepared for the ball bearings. They are fixed on the bottom of the block. The driven disc is cut to a small diameter. It should also be noted that it is important to fix the stops securely. A cover must be attached to the rear of the gearbox.

Gearboxes with rear pusher arrangement

Reducing reducer with rear position of pushers is in great demand. First of all, it should be noted that the models are compact. In this case, the devices are coping well with large overloads. Disadvantage of the models can be called fast wear of the discs. This is due to the friction of the stops. If necessary, you can make modifications yourself.

To this end, experts recommend to prepare a narrow block, install discs with a roller mechanism. It is more advisable to lay the gears after the pushers. Also it should be noted that there are modifications with brake stops. The pushers in this case are fixed to the rack. To change gears, you need to install a lever. After that, the master disc is fixed. The cover for the reducer can be selected with a screw connection. Pressure plates, as a rule, are fixed near the front post. The holder for models is suitable with or without emphasis. If you believe the reviews of specialists, then the most popular are reducers for two pushers.

Feedback on single-stage modifications

Most experts are positive about single-stage reducers. However, it is important to understand that quality models are assembled with transitional pushers. They use sharpened heads, they do not rub against discs. It is better to install the reducer shaft behind the partition. The gear is most often fixed in front of the rack.

Also it should be noted that there are compact modifications with a small shaft. They have small clamping disks, the device is not capable of supporting high engine speeds. The holders are installed in a cylindrical shape. Pressure plates are used with and without adapters. To reduce the frictional force, rollers are used, and the bearings are installed at the base of the shaft. Particular attention during assembly is important to give the unit. To the body withstand high loads, it must be thoroughly dispersed. At the end of the job, it will only be necessary to weld the lid.

Assembly of two-stage devices

The two-stage reduction gearbox is capable of operating with high-power asynchronous motors. Modern models are produced with longitudinal pushers. If necessary, a two-stage modification can be made independently. For this purpose, a block is taken and working disks are placed.

The shaft is important to carefully grind and solder a wide head. To fix the gear, a small rod is used. The lock is most often installed in the front of the gearbox. The abutment can be carved from an ordinary steel plate of small thickness. The modification shaft must not touch the work disks.

Also it should be noted that the devices are folded with the coupling and without it. If we consider the first option, then the clutch lever is installed in the block. In this case, the spring is selected with a small diameter. The pressure stop is better to fix on the device box.
