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 8 clamped between stop 3 and pressing 5 disks via pressing spring 9. Pressing disk 5 carries rods 6 which are provided with end stops 7 and enter openings made in intermediate disk 11. Disk 11 is pressed by spring 13 to bearing disk 10 secured to clutch part 1. Balls 12 are received in sockets of varying depth between bearing disk 10 and intermediate disk 11. In overloading, force, which occurs at balls 12, acts in the direction of the pressing force exerted by spring 13 and presses out intermediate disk 11 to the right. The disk moves over rods 6 and abuts against end stops 7. Spring 9 is interposed between pressing disk 5 and bearing disk 10. EFFECT: enhanced reliability. 2 dwg
