The speed reducer plays the role of matching the speed and the transmission torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. Its purpose is to reduce the rotation speed, and the installation is convenient and the structure is reasonable. The more widely used is the common accessories in air compressors.

Here's a brief introduction to the common faults in the operation of air compressor parts reducer:

1. Air compressor parts wear. Air compressor reducer wears very slowly during normal operation, and some air compressor reducers can be used for more than 10 years. If the wear rate is faster, it is necessary to consider whether the selection is correct, whether it is overloaded, and the reasons for the material, assembly quality, or use environment of the air compressor accessories.

2. Air compressor reducer heats up and leaks. In order to improve efficiency, air compressor accessories air compressor reducer generally use non-ferrous metal compressor accessories, worms are using harder steel. Because it is a sliding friction drive, more heat will be generated during operation, resulting in a difference in thermal expansion between the components of the air compressor reducer and the seal, thereby forming gaps in the mating surfaces, and the lubricating oil solution will become thin due to the temperature increase. Easy to leak. There are four main reasons for this situation:

First, the mix of materials is unreasonable;

The second is the poor quality of the surface of the meshing friction surface;

Third, the choice of the amount of lubricant added is incorrect;

Fourth, poor assembly quality and use environment.

3. Worm bearing damage. In case of failure, even if the screw-type air compressor gearbox seals well, the gear oil in the air compressor reducer is often found to be emulsified and the bearing is rusted, corroded, and damaged. This is because after the air compressor reducer runs for a period of time, the temperature of the gear oil is increased and the condensed water produced after the cooling is mixed with the water. Of course, it is also closely related to the bearing quality and assembly process.

4. Transmission small helical gear wear. Generally occurs in the vertical installation of air compressor reducer, mainly with the amount of oil added and the type of oil. In the vertical installation, it is easy to cause insufficient lubricating oil. When the air compressor reducer stops running, the transmission gear oil between the motor and the air compressor reducer is lost, and the gears are not properly protected by lubrication. When the air compressor reducer starts, the gears may not be effectively lubricated and cause mechanical wear or even damage.
