    摘要： The separator ring to be used with thrust bearings is an annular member with a plurality of circumferentially separated roller engaging portions. The rollers have outer ends constructed to mate with the roller end engaging portions of the annular member. The roller engaging portions on the annular member may be protrusions extending radially inwardly toward the axis of the bearing with the rollers having depressions on the outer ends for receiving the protrusions or alternatively, the roller engaging portions may be radially outwardly extending depressions with the rollers having outer surfaces which fit into the depressions.

    摘要： An improved structure of linear actuator includes an actuator including a gear set having a friction portion located at the periphery of the gear shaft of a driven gear thereof, a one-way bearing mounted on the gear shaft for rubbing against the friction portion to brake the driven gear from reverse rotation, a driver for driving the gear set and a transmission mechanism including a lead screw coaxially coupled to and rotatable by the gear shaft of the driven gear and a retractable tube assembly coupled to the lead screw and movable by the lead screw between an extended position and a received position, and a stopping mechanism including a thrust bearing coupled to the gear shaft of the driven gear and stoppable against an inner race of the one-way bearing inner race to bear an axial thrust load.
