A reduction gear is a device that is designed to convert torque. Worm, planetary and combined modifications are distinguished. The engine with gearbox is able to work at high speeds. The standard model consists of a shaft, pushers and gears. If necessary, a down-type device can be made independently.
Worm Modification Scheme
The scheme of the worm gear includes a wide disk, next to which is the gear. The first pusher is located at the base of the gearbox. In this case, the coupling is mounted in front of the housing. To make the device yourself, first of all, a stand under the shaft is cut. Next, you need to fix the disks. The solder is the last to be soldered.
Planetary gear assembly
This reduction gear for an electric motor is distinguished by the fact that it uses a two-chamber gearbox. Pushers for modifications are installed in different sizes. To make the device with your own hands, a wide block is prepared. Next, it is important to install the pushers. The clutch is directly fixed to the clamping spring.
Experts recommend sharpening the rack in advance and weld the supports on it. The gear is fixed at the rear of the gearbox. The pressure plate is installed only with emphasis. The clamps may be mounted with a roller mechanism. It should also be noted that there are many home-made modifications with additional stops that stabilize the shaft.
Helical gears
Recently, a cylindrical home-made reduction gearbox has been actively used. With your own 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 the disks is prepared. The gear shaft is fixed to the stand.
The holder is allowed to do with emphasis. Ball bearings are fixed at the base of the shaft. The pressure discs of the models can be of different sizes. If we consider compact devices, then the spring should be installed with a small diameter. It should also be noted that the gears are stacked behind the shaft. The pushers should not be in contact with the disc. A cover is screwed onto the front of the case.
Conical model drawings
This reduction gearbox can be made with longitudinal pushers. Drives are most often mounted on a short rack. To change the clutch, a lever is installed. Many modifications are assembled with a transitional holder. The shaft is fixed behind the stand. A clutch is used to adjust the tension. At the end of the work, it remains only to fix the cover. An engine with a reduction gear is able to operate at a frequency of 50 Hz.
Combined device reviews
Combined speed reducers are highly regarded among professionals. If you believe the reviews, then the models are well suited for induction motors. Pushers are more suitable for use from steel plates. For installation of disks stops are used. The coupling for versions is fixed behind the shaft. If you believe the reviews of experts, then the latch can be cut from a conventional plate. It should also be noted that it is more advisable to install the cover with a screw clamp.
Single Lock Modifications
Making a reduction gear with your own hands is very simple. Pushers in this case must be installed under the stops. The box for modification can be selected single-chamber type. Gears are allowed to use with a clip. Push disks are installed with a roller mechanism. The clamping disk is fixed in front of the pusher. To install the spring, you need to use a hammer. The clutch is mounted under the disc. Ball bearings may be used in different sizes.
Dual Lock Devices
Modifications to the two latches stack with a dual camera. In total, two disks will be required for assembly. Directly, the clutch is selected with a support spring. Many experts say that pushers are more appropriate to use a U-shaped. A gear lever is used to shift gears. If you believe the reviews of experts, then gears need to be stuffed for a very long time. In this case, it is important to fix the shaft at the base of the camera. At the end of the work, it remains only to make a holder for the rollers.
Front Pusher Models
Reducing gearboxes for front-mounted pushrod walk -behind tractors are capable of maintaining high revolutions of the induction motor. Holders for modifications are installed with roller mechanisms. Many models fold with longitudinal stops. Before starting the assembly, a chamber is prepared for ball bearings. They are fixed on the bottom of the block. The driven disk is machined with a small diameter. It should also be noted that the emphasis is important to securely fix. A cover must be attached to the back of the gearbox.
Rear Pusher Gearboxes
The rear pusher reduction gear is in great demand. First of all, it should be noted that the models are compact. At the same time, the devices cope well with large overloads. The disadvantage of the models is the rapid wear of the disks. This is due to friction stops. If necessary, you can do the modification yourself.
To this end, experts recommend preparing a narrow block, installing discs with a roller mechanism. It is more expedient to stack a gear wheel after pushers. It should also be noted that there are modifications with brake stops. Pushers in this case are fixed on a rack. To change gears you have to install a lever. After that, the master disk is fixed. The gearbox cover can be selected with a screw connection. Push disks are usually fixed near the front pillar. The model holder fits with or without emphasis. If you believe the reviews of experts, then the most popular are gearboxes for two pushers.
Reviews of single-stage modifications
Most experts respond positively to single-stage gearboxes. However, it is important to understand that quality models are assembled with transitional pushers. They use sharpened heads, they do not rub on disks. It is more expedient to install a reducer shaft behind a partition. The gear is most often fixed in front of the rack.
It should also be noted that there are compact modifications with a small shaft. They have small clamping discs, the device is not able to maintain high engine speeds. Holders are mounted cylindrical. Push disks are used with and without adapters. To reduce the friction force, rollers are used, and bearings are installed at the base of the shaft. It is important to pay special attention to the unit during assembly. In order for the body to withstand heavy loads, it must be carefully soldered. At the end of the work, it remains only to weld the cover.
Assembly of two-stage devices
A two-stage reduction gear is capable of working with high-power induction motors. Modern models are available 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.
It is important to sharpen the shaft and solder the wide head. A small stock is used to fix the gear. The latch is most often installed in the front of the gearbox. The emphasis can be machined from a conventional steel plate of small thickness. The modification shaft must not come into contact with the working disks.
It should also be noted that the devices are folded with and without a clutch. 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. It is better to fix the pressure stop on the device box.
