Types of reducers (photo). Types of gas reducers

Reducers have been used for many decades in the most diverse areas of instrument engineering and engineering. But the most widespread such devices have been in the automotive industry in the manufacture of aggregates and vehicle units. Different types of gearboxes are installed on cars, scooters and motorcycles. For the first time this equipment was manufactured at the Tula factory, but at that time it was a real deficit, so only the richest people could buy it.

Currently, such devices are very common, but only now they are no longer in high demand. That's why it's very difficult to find parts for them. Sometimes even an accurate gearbox drawing may be needed to create quality parts.

Types of devices

There are the following main types of gearboxes:

• Worm;
• Cogged;
• Motor-reducers;
• Hydraulic.

All of them are endowed with their own peculiarities and are used in a variety of spheres. The device of this type can be found in virtually any car. Each of them is endowed with an additional gear shaft. The efficiency of the reducer depends on the type.

In addition, the installation of such a device is very simple, but you must be very careful not to damage the shaft of the primary gearbox. And for its creation use a minimum of materials, and at installation even any frame designs are not necessary. Manufacturers also took into account the fact that it is necessary to create such a device that would fully meet all the needs of consumers. Therefore, there are kinds of reducers of different size and power.

Planetary and cylindrical gearboxes

These types of reducers are most often used in modern mechanisms and nodes of general industrial use. They are produced according to the following scheme: the output shaft and the electric motor are very close to each other. Cylindrical reduction gears are the most popular version of all existing to date. They are designed to change the speed of rotation in the transmission of torque. Modifications of such devices can be one- and three-step.

All kinds of cylindrical gearboxes are reliable and durable, therefore the machines and equipment possessing these installations are very durable and productive.

Worm gearboxes: types and purposes

Worm gearbox is a special kind, having a rather unusual body with a screw thread profile. It is used when transferring motion between crossed axes, which are usually located at a right angle. The main advantage of this device is the possibility of obtaining a large gear ratio in one stage .

Bevel-helical gearboxes

Such devices also have their own characteristics. Their working elements are endowed with a very original constructive solution, but Perform the same functions as the other types of gearboxes: change the speed of rotation in the transmission of one rotational motion to another. In comparison with other varieties such devices have a rather high efficiency. Used most often for various drives of conveyor lines, mine tractive electric locomotives, etc.

As it was already noted earlier, the types of gearboxes, photos of which are placed in the article, are applied each in its specific field. It should be remembered that the correct choice of such a device guarantees a long period of its operation, and, conversely, vice versa. Because it is worth paying special attention to the acquisition of technology, which will be installed in the car.

Disassembly of the reducer

The gearbox housing has certain features, due to which the disassembly of such a device is carried out according to a certain scheme. This process is necessary if, for any reason, the gear unit has ceased to function normally. Many people act very wrong: when a reducer breaks down, it is simply thrown away. But if you competently approach this case, such equipment can be repaired, after which the technique will function just as before. In addition, as mentioned earlier, it is rather difficult to purchase such spare parts for your car or scooter, so you should not waste them.

Disassembly stages

• If the gearbox has been disassembled for some time, then, first of all, it would be nice to clean it of dirt and dust.
• Further, it is necessary to unscrew all the tightening reducer bolts. Then use a construction hair dryer to warm the device from all sides, and then knock on the body with a wooden kyanik. This should be done until two halves are formed.
• It is necessary to find out, as a result of which there was a breakdown. Naturally, there are different types of gearboxes, so it is important to take this into account when searching for the cause of the malfunction. As a rule, reducers fail for 2 main reasons: first - the primary shaft or its bearing has broken, the second - the teeth have worn off the gears. If the parts are broken, they will have to be thrown away.
• Replace the gears and bearings with new spare parts.
• Remove the locking plate.
• Remove the retaining ring and pull out the shaft from the cup.
• Before assembling all the parts it is necessary to check their integrity.
• After the gearbox housing is completely assembled, it can be returned to the space reserved for it.

Features of gas reducers

The gas reducer is a device used to equalize the pressure level when the gas is supplied. Such a device can effectively maintain the desired pressure. In addition, it can, if necessary, reduce its level. Thanks to the reducer, you can save a lot, which is very important today.

There are such types of gas reducers: propane and methane. The first one is used for welding and cutting metal. The second is installed on vehicles to save fuel. It is worth noting that both these options have their own unique features.

Propane reducers

Such devices are most often used in domestic and industrial conditions. They can be found in modern homes, where they use household gas cylinders.

Methane reduction gears

They are actively used on various cars. Today many drivers give their preference to gas, because it is possible to travel on it more economically. The reducer makes it possible to save and to ensure safety. A lot depends on the quality of the device. Therefore it is recommended to buy it in a checked place and only with a certificate of production.

Types of gearboxes VAZ

Depending on the components of such devices can be of different types. Gears of the main gear are endowed with an unusual shape, and the teeth are at different angles. This is due to the fact that the hypoid transfer is applied. Its main advantages are:

• Work without jerks;
• Low noise level;
• Reduced load on each of the teeth.

The whole mechanism, therefore, can be used for a fairly long time and, as practice shows, is quite reliable. Reducers can have a gear ratio of 3.9, 4.1, 4.3, 4.44. It should be noted that such devices are installed on many other models of domestic cars.
