S-Type Pin-guided clutch with three flyweights

Construction and mode of operation

The cylindrical hub carries three flyweights which are located by and can slide on cylindrical pins . Inside the flyweights there are tension springs which restrain neighboring flyweights until centrifugal force overcomes the spring force. Then the flyweights lift from their seats and the linings on the flyweights contact the inside diameter of the clutch drum. Friction between the linings and the clutch drum allows torque to be transmitted.

1) The transmitted power increases as the width B is increased.
2) Tapered bores and special dimensions can be manufactured on request.
3) Motor power is calculated using a safety factor of 2.

Final selection of the clutch should be accomplished by SUCO!
