SAFETY FRICTION CLUTCH Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: driving 1 and driven 2 clutch parts are interconnected through friction disk 3 clamped between the thrust disk of clutch part 1 and pressing disk 4 mounted for permitting axial and periphery movements with respect to clutch part 1. The pressing effort is exerted by pressing spring 5. The pressing out stabilizing unit of the clutch is constructed as balls 9 received in sockets of varying depth between thrust disk and pressing out bushing 8. The bushing is mounted for permitting movement along the hub of clutch part 1 and coupled with pressing disk 4 through guide key 7. When a load is applied to the balls, a force occurs that reduces the force which is exerted on the thrust disk of clutch part 1 by pressing spring 5. EFFECT: improved accuracy of clutch actuating. 2 dwg
