CENTRIFUGAL CLUTCH Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: axially alined driving clutch member 1 and driven clutch member 2 are mounted for permitting interaction with each other by way of centrifugal blocks secured to plate springs 5 that are symmetrical with respect to the axes of pivots 7. In setting the clutch in operation, total forces exerted on top and bottom blocks 3 tend to bring top and bottom blocks close to clutch part 2 and left and right blocks 3 apart from clutch part 2. With increasing the speed of rotation of clutch member 1, left and right blocks 3 approximate to clutch member 2. As a result respective parts of spring 5 are bent and flexible torque that acts on the parts of spring 5 abutting against top and bottom blocks 3 increases. EFFECT: enhanced reliability. 4 dwg
