W-Type Pin-guided clutch with two flyweights

Construction and mode of operation

The cylindrical hub carries two flyweights, which are located by and can slide on cylindrical pins. The tension springs are attached outside the flyweights to lining carriers. The tension springs restrain the flyweights until centrifugal force overcomes the spring force. Then the flyweights lift from their seats and the linings 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!
