SAFETY FRICTION CLUTCH Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: drive half-clutch 1 and driven half-clutch 2 installed concentrically are coupled with the aid of flexible friction members 2 mounted on blocks 4. Pressing of members 3 against inner surface of half-clutch 2 is carried out with pressure springs 6 which are positioned uniaxially to carriers 5 anchored on half-clutch 1. Blocks 4 are put on carriers. Clutch may have number of carriers 5 equal to number of blocks 4 or their number may be equal to double number of blocks 4. Torque between half-clutches 1 and 2 is transferred due to friction between half-clutch 2 and members 3. Friction force is excited with spring 6 placed on side of running-on end of member 3. EFFECT: enhanced efficiency of clutch. 2 dwg
