The most important factor for selection of a centrifugal clutch is the amount of power to be trans- mitted. Knowing the power available from the drive motor and the operating speed, the torque to be transmitted can be calculated and the size of the clutch determined. For the vast majority of drives, there is a wide range of clutch types and designs. Our sizes 01 to 13 cover depending on engagement and operating speeds ֖ a torque range up to ca. 2000 Nm. To be sure that clutches operate correctly, grease, oil and moisture must be kept away from their friction surfaces. Calculating the torque:...

Performance factor for torque transmission: The performance factor for torque transmission is a measure of the capacity of a clutch to provide suffi cient friction to transmit the power applied to it when the fl yweights are in contact with the drum. Whereas a W-Type clutch has a performance factor of 1.0, an F-Type clutch of the same size with self-increasing effect is capable of transmitting a torque approximately 2.5 times greater at the same speed and with the same fl yweight mass. The asymmetric pivot clutch achieves a power factor of ca. 1.75 or ca. 1.25 depending on the direction of rotation....

The fl yweights 2 are seated on the profi led hub 1 and are held against it by tension springs 3 , which are hooked into the linings 4 . Discs locate the fl yweights axially. Each lining has a crimping on its inner surface to locate it on the fl yweight. This prevents the linings from moving sideways. As the profi led hub rotates, the centrifugal force acting on the fl yweights overcomes the spring force. When the speed is high enough, the linings contact the clutch drum 5 , and friction between the linings and the drum allows torque to be transmitted between the two. 1 Hub 2 Flyweights 3 Tension...

The cylindrical hub 1 carries three fl yweights 2 which are located by and can slide on cylindrical pins 3 . Inside the fl yweights, there are tension springs 4 which restrain neighbouring fl yweights until centrifugal force overcomes the spring force. Then the fl yweights lift from their seats and the linings 5 on the fl yweights contact the inside diameter of the clutch drum 6 . Friction between the linings and the clutch drum allows torque to be transmitted. 3 Cylindrical pin 2 Flyweights 1 Hub 4 Tension spring 5 Lining 6 Clutch drum > In contrast to F-Type clutches, the linings of pin-guided...

The cylindrical hub 1 carries two fl yweights 2 , which are located by and can slide on cylindrical pins 3 . The tension 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 > The W-Type combines the advantages of F-Type...

Flyweights 1 are normally mounted so that they can pivot on pins 5 , which are fi tted to a fl ange. There are tension springs 2 which restrain neighbouring fl yweights until centrifugal force over- comes the spring force. Then the fl yweights lift from their seats and the bonded linings 3 contact the inside diameter of the clutch drum 4 . Due to the asymmetric arrangement of the fl yweights, the torque that can be transmitted by this type of clutch depends on the direction of rotation. 1 Flyweight 2 Tension spring 3 Lining 4 Clutch drum 5 Shoe pivot > P-Type clutches are extremely narrow.
