W-Type Pin Guided Centrifugal Clutch

Product Type: Centrifugal Clutches

The W-Type combines the advantages of F-Type and S-Type clutches. The tension springs are easily accessible and the linings removable, the parts subject to wear are easy to replace.

As with the S-Type, the guide pins provide accurate guidance for the flyweights, which ensures quiet operation of the clutch. For this type of clutch, the performance factor for torque transmission is 1.0.

The cylindrical hub (1) carries two flyweights (2) , which are located by and can slide on cylindrical pins (3). The tension springs (4) are attached outside the flyweights to lining carriers (5). 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 (6). Friction between the linings and the clutch drum allows torque to be transmitted.
