Abstract

PURPOSE:To accelerate the grease lubrication and prevent the local abrasion and improve durability by installing a bearing as inertia body supporting device and a one-way bearing which acts between the both inertia bodies in series with the bearing, between the both inertia bodies. CONSTITUTION:When a driven side inertia body 14 moves in the directions A and B for a driving side inertia body 12, an outer race 2a moves in the directions A and B, and also a bearing ball 5 shifts in the directions A and B. When a driving side inertia body 12 moves in the A direction for the driven side inertia body 14, an inner race 1a moves in the A direction. However the revolution-shift of a bearing ball 6 is suppressed by a projection 16. When the inner race 1a moves in the B direction, the bearing ball 6 shifts in the B direction. When the bearing ball 5 shifts in the A direction, the both bearing balls shift in the separation direction. Therefore, the grease lubrication is accelerated, and the local abrasion is prevented, and durability can be improved.

(Prior art) In devices that transmit rotational torque, in order to prevent torque fluctuations in the low rotation range from being transmitted to the wave shaft,
An inertial body consisting of a rotating member incorporated in a device for transmitting rotational torque is divided and arranged concentrically, and a drive-side inertial body is coupled to a drive shaft, and a hysteresis mechanism is provided between a wave-side inertial body and the inertial body. and a damper mechanism. A bearing is disposed between the graphical bodies, and one side supports the other via the bearing, and both are supported so as to be relatively rotatable.

(Problems to be Solved by the Invention) In the conventional bearing device, as shown in FIG. 4, the amount of relative rotational movement of the image-sensitive bodies 41 and 42 when absorbing torque fluctuations is small; bearing ball 43
moves only between 43A and 438, and only repeats the reciprocating movement therebetween. As a result, the bearing balls always come into contact with only the same portion of the inertial body, causing insufficient lubrication and local erosional wear, and further reducing the durability of the bearing. For example, when the engine speed is low, the minute amplitude is usually about 0.03 radian, and in the case of a ball, it does not rotate even once.
