Generally speaking, the composition of the reducer is very simple. From the appearance, the reducer consists of a high-speed shaft, a low-speed shaft and a shell. The high-speed shaft and the motor shaft are connected by damping couplings (such as elastic pin couplings, coupling with elastic spider, etc.). ). Generally, there is a brake between the reducer and the motor. The output shaft of the reducer is a low-speed and high-torque shaft, which is generally connected with the upper drum of the wire rope and used to pay off the wire rope. As for the inside of the reducer, it is driven by various gears. Because of different requirements, the structure and transmission chain are very different, so I won't go into details here.

The installation methods of reducer are horizontal, vertical and suspended, and there are many kinds.
