Centrifugal brake
SUCO
Besides centrifugal clutches, centrifugal brakes are becoming increasingly important.
A decisive advantage of centrifugal brakes over conventional brakes is that they operate without an external power supply.
The brake, mounted on a shaft, starts to brake a drive shaft at a defined speed. Centrifugal force causes the flyweights to lift from the hub so that their linings contact the inside diameter of the brake drum. This action creates a braking torque.
As soon as the speed of rotation of the system falls, the tension springs return the flyweights to their initial positions.
It is a fundamental principle of centrifugal brakes that they cannot brake a system to a standstill, i.e. the system speed searches for an equilibrium condition between the speeds determined by load torque and braking torque.
Although centrifugal brakes are governed by the same technical principles as centrifugal clutches and also use similar components, brakes call for additional investigation of their conditions of use.
