Background
A transmission is a component or mechanism that transfers power from one part of a machine to another to move or operate the machine or a machine component, referred to as a transmission. According to different working principles, the transmission mode can be divided into: mechanical transmission, fluid transmission, electrical transmission, and compound transmission. Wherein, the mechanical transmission refers to the transmission of power and motion by using a mechanical mode. Mechanical transmissions can be divided into two categories: the transmission mechanism is driven by the friction force between the parts and the transmission of the driving part and the driven part, or by the middle part.
In the prior art, mechanical transmission devices include hydraulic transmission, pneumatic transmission, gear transmission, chain transmission and belt transmission, and mainly adopt transmission for changing the rotating speed. Because there is damping between each drive disk assembly, and then reduced actual transmission efficiency.
