DEVICE FOR COMPENSATING ROTATIONAL IMPACT

摘要

PURPOSE: To enhance the torque transmitting function and prolog the durable lifetime by holding a rolling bearing in such a way as not capable of moving in the axial direction on masses on which a friction clutch is supported through a disc-shaped constituent member. CONSTITUTION: Masses 3 and 4 are supported with possibility of relative rotation through a supporting mechanism 15 equipped with a single row ball bearing 16 and the inner race 19 of the ball bearing 16 is attached to a protrusion 20 on the mass 3 intruding into a notch 18 provided in the mass 4 upon extending in the axial direction from a crank shaft 5 while the outer race 17 of the ball bearing 16 is through a heat insulating material 24 into the notch 18. A coned disc spring 35 attaches a friction cylinder 37 by pressure to a disc- shaped constituent member 30, and the bearing 16 is fastened between the constituent member 30 and a shoulder 31 integrally formed with the mass 4 supporting a friction clutch and supported on the mass 4 in such a way as not capable of moving in the axial direction. This establishes improvement of the torque transmitting function and prolongation of the durable lifetime.
