W-Type Pin-guided clutch with two fl yweights
Construction and mode of operation
The cylindrical hub 1 carries two fl yweights 2 , which are located by and can
industrial slide on cylindrical pins 3 . The tension
industrial springs 4 are attached outside the fl yweights to lining carriers 5 . The ten-sion springs restrain the fl yweights until centrifugal force overcomes the spring force. Then the fl yweights 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. 2 Flyweight 3 Cylindrical pin 1 Hub 4 Tension spring 5 Lining 6 Clutch drum
Advantages:
The W-Type combines the advantages of F-Type and S-Type clutches. Because 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 fl yweights, which ensures quiet operation of the clutch. For this type of clutch, the performance factor for torque transmission is 1.0.
