A transmission mechanism is a device that transfers power from one part of a machine to another, facilitating the movement or operation of the machine or its components.
(1) Adjust the output torque of the power machine to satisfy the needs of the working machine;
(2) Convert the motion output of the power machine into the desired form for the working machine, such as transforming rotary motion into linear motion or vice versa;
(3) Distribute the mechanical energy from one power machine to multiple working machines, or gather the mechanical energy from multiple power machines to a single working machine;
(4) Achieve other special objectives, such as simplifying control, assembly, installation, maintenance, and ensuring safety of the machine, etc.
According to different working principles, the transmission mode can be divided into:
It refers to the transmission that uses mechanical means to transmit power and motion, which can be divided into two categories:
- Frictional transmission, relying on power and friction transmission by friction between parts
- Intermeshing transmission, which transmits power or motion through the engagement of the active member with the driven member, or through the engagement of the intermediate member.
It refers to a type of transmission that uses fluid as a working medium. This can be further divided into two categories:
- Hydraulic transmission, which transmits energy through the static pressure of a liquid.
- Pneumatic transmission, which uses gas pressure to transfer energy.
Additionally, hydraulic transmission can also be classified as relying on hydrodynamic action between the impeller and the liquid to transfer energy.
It refers to the utilization of electric motors to convert electrical energy into mechanical energy, which is used to power various types of production machinery, transportation vehicles, and devices that require movement in daily life. This is commonly referred to as electric propulsion.
Refers to a mechanism or structure that utilizes multiple transmission modes.
