Abstract

This spring clutch has a braking device integrally connected to the actuator assembly. The device consists of helical spring 10 fitted with a slight inte rfe rence fit ove r output shaft 12 at the cente r of the spring 10. One end 14 of spring 10 fits over stationary hub 16 with a slight clearance fit. The other end 18 of spring 10 fits over continuously running input hub 20 with a slight clearance fit. A single actuator 22 controls the device. To operate the clutch, actuator 22 is pivoted so that drive rolle r 24 engage s end 18 of spring 10 and pre sse s it against input hub 20. Thus spring 10 wraps around hub 20 and output shaft 12, rotating such shaft.

Clutch Brake Device

This spring clutch has a braking device integrally connected to the actuator assembly. The device consists of helical spring 10 fitted with a slight inte rfe rence fit ove r output shaft 12 at the cente r of the spring 10. One end 14 of spring 10 fits over stationary hub 16 with a slight clearance fit. The other end 18 of spring 10 fits over continuously running input hub 20 with a slight clearance fit. A single actuator 22 controls the device. To operate the clutch, actuator 22 is pivoted so that drive rolle r 24 engage s end 18 of spring 10 and pre sse s it against input hub 20. Thus spring 10 wraps around hub 20 and output shaft 12, rotating such shaft. To disengage the clutch, actuator 22 is pivoted in the opposite direction, releasing drive roller 24 and engaging end 14 of spring 10 with brake pad 26 to press that end of spring 10 against stationary hub 16. Thus, spring 10 contracts on stationary hub 16 and output shaft 12 so that such 12 is stopped. This device ope rate s in one direction only, depending on the direction of the winding of spring 10.
