General technical information on centrifugal clutches and brakes How do centrifugal clutches or brakes work? Centrifugal clutches and brakes use centrifugal forces to transmit power (clutch) or to limit speed (brake). As the brakes are based on a physical principle, centrifugal clutches or brakes do not require any additional external power supply, which makes them a perfect solution for safety applications. Centrifugal clutches and brakes consist of a driving shaft ©. Around the driving shaft, there are flyweights © mounted, which are kept on the shaft by springs ®. On the outer side of the...

Construction of a centrifugal clutch /brake Typical applications for centrifugal clutches: Centrifugal clutches are mainly used as a start up clutch. A centrifugal clutch allows the usage of a smaller motor, because the motor can start loadfree until it has reached its optimum operating speed, at which the load is smoothly added by the centrifugal clutch. Typical applications for centrifugal brakes: The main application for centrifugal brakes is limiting the speed of e.g. • descending weight or persons • industrial applications (e. g. safety- and fire doors) • leisure applications (e. g. Go Kart...

General technical information on centrifugal clutches and brakes Calculating the torque: M = torque [Nm] n = speed of rotation [rpm] P = power [kW or hp] M = 9550 ■ - [kW] M = 7121 ■ - [hp] Selection matrix of SUCO centrifugal clutches Performance factor The performance factor is a measure to compare the power transmission of clutches. The W-Type clutch has a performance factor of 1.0. The F-Type at the same size and the same flyweight mass can transmit 2.5x more torque. Engagement speed: The engagement speed of centrifugal clutches indicates the speed at which the centrifugal forces overcome...

Centrifugal brakes: Standard centrifugal brakes are used to limit speed - they cannot bring a system to standstill. The basic principle is to keep a balance between the load of the driving side and the braking torque. During the operation there is a constant friction which generates heat. The amount of generated heat depends on various factors: • Transmitted braking torque • Brake speed • Duration of the braking operation • Size of the friction surface • The mass of the brake drum that has to be heated Over the braking time the temperature curve rises very steeply at the start and then gradually...

Dif ferent solutions, driven-side To accommodate the variety of transmission requirements, SUCO offers a wide and flexible product range. Both axial and radial drives can be supplied. All centrifugal brakes and clutches must only be used in conjunction with a suitable drum or belt pulley. The operation of a clutch or brake without a suitable drum or belt pulley is forbidden. Non-compliance can result in injury to persons. Core version -KThis version without a drum is supplied when a clutch or brake drum already exists in the customer's set up, or a suitable component for this purpose is available...
