    • The invention concerns a gear, which comprises a shaft (12) and on it a gearwheel (13), which is in engagement with a gearwheel (17) mounted on a shaft (16). The shaft (16) comprises bearings (18 and 19) at both sides of the gearwheel (17) between the frame (11) and the shaft (16). The gear comprises a spring/springs (23a1, 23a2...), which is/are fitted to act with a force (F) upon the outer race (18') of the rolling members (20a1, 20a2...) of the bearing (18). Between the circumferential face (C1) of the outer race (18') and the gear (10) frame (11) or a connected part there is a glide fitting. In this connection the force effect is transferred further through the rolling members (20a1, 20a2...) of the bearing (18) to the inner race (18'') of the bearing (18) and further to the bearing means (19) placed at the opposite side of the gearwheel (17). In this way the play in the bearings (18 and 19) placed at both sides of the gearwheel (17), between the rolling members (20a1, 20a2...) and the bearing (18, 19) races (18', 18''; 19', 19''), is eliminated.
    • 本发明涉及一种齿轮,其包括轴(12)并且在其上的与安装在轴(16)上的齿轮(17)接合的齿轮(13)。 轴(16)包括在框架(11)和轴(16)之间的齿轮(17)两侧的轴承(18和19)。 齿轮包括弹簧/弹簧(23a1,23a2 ...),弹簧/弹簧(23a1,23a2 ...)被安装成与滚动部件(20a1,20a2 ...)的外圈(18')上的力(F) 轴承(18)。 在外圈(18')的圆周面(C1)与齿轮(10)框架(11)或连接部分之间有滑动配件。 在这方面,力效应进一步通过轴承(18)的滚动部件(20a1,20a2 ...)传递到轴承(18)的内圈(18“),并且进一步传递到轴承装置(19) )放置在齿轮(17)的相对侧。 以这种方式,放置在齿轮(17)两侧的轴承(18和19)之间的滚动部件(20a1,20a2 ...)和轴承(18,19)之间的间隙(18',18) ''; 19',19'')被消除。

    • A gearbox assembly (1) for an electric power assisted steering apparatus comprises a gearbox housing (2) which houses a worm shaft (3) and a gear wheel (7), the worm shaft being supported relative to the housing by a main bearing assembly (5) at an end closest to the motor (4) and by a tail bearing assembly (6) at an end furthest from the motor, and the gear wheel being supported by an output shaft (8) having at least one end that provides a take-off from the gearbox assembly, in which the tail bearing assembly is free to move relative to the housing through a limited range of motion that enables the worm shaft to move radially away from the axis of the wheel gear. A biasing means applies a biasing force to the tail bearing assembly that biases the worm shaft into engagement with the wheel gear. The main bearing assembly comprises an inner race and an outer race separated by bearing elements, the outer race being supported by a carrier (11) that is supported by an axle that is in turn secured to gearbox housing, the axle defining a pivot axis for the worm shaft that is located on the side of the worm shaft closest to the wheel gear and extends in a direction orthogonal to the axis of the worm shaft and parallel to the axis of the wheel gear.
    • 一种用于电力辅助转向装置的变速箱组件(1)包括容纳蜗杆轴(3)和齿轮(7)的变速箱壳体(2),所述蜗杆轴通过主轴承组件相对于壳体支撑 (5)在最靠近电动机(4)的端部处,并且在远离电动机的端部处由尾轴承组件(6)支撑,并且齿轮由输出轴(8)支撑,输出轴(8)具有至少一端, 来自齿轮箱组件的起飞,其中尾轴承组件通过有限的运动范围自由地移动,使得蜗杆轴能够径向地远离齿轮的轴线移动。 偏压装置向尾轴承组件施加偏压力,该偏压力将蜗杆轴偏置成与齿轮啮合。 主轴承组件包括内座圈和由轴承元件分开的外座圈,外座圈由承载件(11)支撑,该承载件由轴支撑,该车轴又固定到齿轮箱壳体,该轴限定枢转轴线 所述蜗杆轴位于最靠近所述轮齿轮的所述蜗杆轴的一侧,并且在与所述蜗杆轴的轴线正交并且平行于所述齿轮的轴线的方向上延伸。
