    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.

    摘要: A cage is provided with guidance and retention elements for the cylindrical rolling elements. The cage includes a radially inner rim including a first flange, and a plurality of first retention tabs extend from the first flange that include first and second lateral surfaces. A radially outer rim includes a second flange, and a plurality of second retention tabs extend from the second flange that include third and fourth lateral surfaces. The first and second lateral surfaces of the first retention tabs and the third and fourth lateral surfaces of the second retention tabs face each of the pockets to define lower rolling element retention elements. Webs include first and second rolling element facing guide surfaces that face adjacent ones of the pockets. Upper rolling element retention elements of the webs are provided on an opposite side of a centerline from the lower rolling element retention elements.

    摘要: An axial bearing arrangement formed substantially of two rotating carrier components (1, 2) with circular ring-shaped end faces (3, 4) and an axial anti-friction bearing (5) arranged between the carrier components (1, 2). This axial anti-friction bearing (5) has a first ring-shaped angle disk (6), which rests on the end face (3) of the first carrier component (1) and which is made from a thin steel sheet, and a second ring shaped angle disk (7), which rests on the end face (4) of the second carrier component (2) and a needle cage (10), which rolls between the axial inner sides (8, 9) of the angle disks (6, 7) and which is formed from a plurality of bearing needles (12) arranged adjacent to one another and held at equal distances to one another by a bearing cage (11), and is lubricated and cooled by a lubricant flow (13) emitted by a shaft which passes centrally through the axial anti-friction bearing (5). According to the invention, a circular ring-shaped ramp disk (14), which is designed as a spring, is arranged between the first carrier component (1) and the first angle disk (6), by which ramp disk a radial annual gap (15) between the first carrier component (1) and the first angle disk (6), which results from the axial clearance of the axial anti-friction bearing (5) in the no-load state, can be sealed to prevent a wrong direction of the lubricant flow (13) and the lubricant flow (13) at the same time, can be systematically routed into the inside of the bearing (16) between the angle disks (6, 7).
