There are usually two types of transmission mechanisms in the transmission chain: one is the transmission mechanism with fixed transmission ratio and transmission direction, such as fixed ratio gear pair, worm and turbine pair, which is called fixed ratio transmission mechanism; The other is the transmission mechanism that can change the transmission ratio and transmission direction according to the processing requirements, such as the change gear transmission mechanism, sliding gear transmission mechanism, etc., which is called the displacement mechanism.

In the transmission device of machine tool, the commonly used transmission parts include pulley, gear, worm turbine, gear rack and screw nut, etc. Through these transmission parts, the power source and the actuator, or the two actuators are connected, which is called the transmission connection. A series of sequentially arranged transmission parts that constitute a transmission link are called transmission chains.
