TRANSMISSION GEAR FOR TORQUE

摘要

A torque-transmitting device has means for absorbing or compensating for rotary impulses by means of at least two gyratory masses (3,4) which are arranged coaxially with each other via a bearing (15) and are rotatable with respect to each other through a limited angle against the action of a damping device (13). One of the gyratory masses (4) has a friction surface which cooperates with a clutch disk (9). In order to increase the working life of the bearing (15) and consequently also to improve the operation of the torque- transmitting device, means (18) are provided between the friction surface of the gyratory mass (4) and the bearing (15) for reducing heat flow between the friction surface and the bearing.
