1. Deceleration or speed change device
The function of the deceleration or speed change device is to change the speed and torque of the prime mover to meet the needs of the working machine.
2. Start-stop reversing device
The start-stop reversing device is used to control the start, stop and change the direction of movement of the working machine.
3. Braking device
When the prime mover stops working, due to the friction resistance, the machine will automatically stop running, generally without braking device. However, the moving components have inertia. When it is necessary to shorten the auxiliary parking time, require the working machine to stop at a certain position accurately and stop immediately in case of an accident, the transmission system shall be equipped with a braking device.
4. Safety protection device
When the machine may be overloaded and has no protective transmission parts (such as belt drive, friction clutch, etc.), safety protection devices shall be set to avoid damage to the transmission system. In order to reduce the size of the safety protection device, it should generally be installed on the high-speed shaft of the transmission system.
When designing the machine, the necessary parts should be selected according to the actual working requirements to determine the composition of the system.
