29. How Many Types of Transmission are available for air compressors?

In the transmission system of an air compressor, it can be generally divided into two methods: direct drive and belt drive.

The direct drive of a screw air compressor refers to the connection between the motor shaft and the rotor of the compressor through a coupling. However, this is not a true direct drive in the strict sense. The direct drive in the true sense means that the motor is directly connected to the rotor and the speed of the two is the same, which is obviously very rare. Therefore, the notion that direct drive involves no energy loss is not accurate.

Belt drive, this transmission method allows for the adjustment of the rotor’s speed by using pulleys with different diameters on the belts.
