OVERRUNNING CLUTCH Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: clutch has driven 2 and driving 3 clutch parts which are axially alined and mounted on shaft 1. The clutch parts are positioned inside housing members 4,5. Two ring concentric grooves of different radii are made on the face of driven clutch part 2. Two ring eccentric grooves of the same radius are made on the face of driving clutch part 3. There are balls 8 between the clutch parts 2,3. Separator 9 is interposed between clutch parts and can have three fixed positions with respect to clutch part 2. The separator has slots 11 which are coincident with balls 8. At one of the end positions of the separator, where it is fixed with screw 10, a torque is transmitted in the direction which is opposite to the direction of rotation of the separator. For changing the direction of transmission of the torque, the separator is set at the other end position. For dummy operation of the clutch, it is required to set the separator at intermediate position and fix it with screw 10. EFFECT: enhanced reliability. 4 cl, 6 dwg
