A brake is a device with functions such as decelerating, stopping, or maintaining a stopped state of moving parts (or moving machinery). It is a mechanical part that stops or decelerates the moving parts in the machine. Commonly known as brakes, brakes.

Brake principle

Definition of brake

A brake is a device that uses frictional torque to reduce the speed of moving parts of a machine or stop it from rotating.

5 conditions that brakes must meet

  1. Sufficient braking torque can be generated.
  2. Simple structure and compact appearance.
  3. Braking is fast, stable, and reliable.
  4. The brake parts have sufficient strength and rigidity, and the brake belt and drum should have high wear resistance and heat resistance.
  5. Easy to adjust and maintain.


The brake is generally set on the shaft with a higher speed in the mechanism (small torque)


Friction brake

Friction brakes can be divided into disc brakes, outer-holding block brakes, internal expansion shoe brakes, band brakes, comprehensive band brakes, double shoe brakes, multi-shoe brakes, simple band brakes, single-disc brakes, Multi-disc brakes, fixed caliper brakes, floating brakes, etc.

Non-friction brake

It can be divided into magnetic particle brake, magnetic eddy current brake, water eddy current brake, and so on.
