What are the transmission modes?

Transmission is divided into three categories: mechanical transmission, fluid transmission and electric transmission.

1. Mechanical transmission is directly realized by using machine parts, in which gear transmission and chain transmission belong to meshing transmission; Friction wheel drive and belt drive belong to friction drive.

2. Fluid transmission is transmission with liquid or gas as working medium, which can be divided into hydraulic transmission with hydrostatic pressure, hydraulic transmission with liquid power and pneumatic transmission with gas pressure.

3. Electric drive is a drive that uses a motor to change electric energy into mechanical energy to drive the working part of the machine. The characteristics of all kinds of transmission are shown in the table.

Importance of mechanical transmission:

Generally, working machines rely on the prime mover to supply a certain form of energy. However, it is rare to connect the prime mover and the working machine directly, and it is often necessary to add a transmission device to transfer power or change the motion state between them:

(1) The speed required by the working machine is generally inconsistent with the optimal speed of the prime mover.

(2) Many working machines need to adjust their speed according to the production requirements, but it is not economical and impossible to achieve this goal by relying on the speed of the prime mover.

(3) In some cases, it is necessary to use a prime Mover to drive several working machines with different working speeds.

(4) For the sake of safety and convenience of maintenance, or because the external dimension of the machine is limited, the prime mover and the working machine cannot be directly connected.
