    • Construction of an electric power-steering apparatus is achieved that, by stably suppressing backlash of an output shaft 6a of an electric motor 5 over a long period of time, is able to stably reduce vibration and strange noise that occurs during operation. The front end section of the output shaft 6a and the base end section of a worm 7 are connected such that torque can be transmitted and such that relative displacement in the axial direction is possible An elastic member 31 having an elastic force in a direction that separates the output shaft 6a and worm 7 is provided in the connecting section between the output shaft 6a and the worm 7. Due to the elastic force of the elastic member 31, together with the tandem arrangement contact angles, the preload is applied to a pair of ball bearings 14a, 14b that support the output shaft 6a with respect to the motor case 13 such that the output shaft 6a can rotate freely.
    • 实现了电动助力转向装置的构造,其通过稳定地抑制电动机5的输出轴6a的反冲很长一段时间,能够稳定地减少运行期间发生的振动和奇怪的噪音。 输出轴6a的前端部与蜗杆7的基端部以能够传递转矩的方式连结,并且能够沿轴向相对移位。弹性部件31在分离方向具有弹性力 输出轴6a和蜗杆7设置在输出轴6a和蜗杆7之间的连接部分中。由于弹性部件31的弹性力以及串联布置的接触角,预载荷施加到一对 滚珠轴承14a,14b相对于马达壳体13支撑输出轴6a,使得输出轴6a能够自由旋转。

    • The invention relates to a bearing assembly (1) comprising two tapered roller bearings (2, 3), each having an inner ring (4, 5), an outer ring (6, 7) and tapered rollers (8, 9) arranged between the rings, wherein the inner rings (4, 5) are mounted in or on a first machine part (10), in particular a shaft, and wherein the outer rings (6, 7) are mounted in or on a second machine part (11), in particular a housing. In order to automatically build a preload in the bearing assembly at an increased operating temperature, according to the invention the outer rings (6, 7) or the inner rings (4, 5) are arranged with a cylindrical seat (11, 12) on an adapter sleeve (14) that carries the rings and has a cylindrical counter-seat (15), wherein the one bearing ring (7) arranged on the adapter sleeve (14) is seated directly or indirectly against an axial stop (16) of the first or second machine part (10, 11), wherein the other bearing ring (6) arranged on the adapter sleeve (14) is seated against an axial stop (17) of the adapter sleeve (14), wherein the axial stop (17) of the adapter sleeve (14) is formed by a radially enlarged or reduced section (18) of the adapter sleeve (14), wherein the section (18) on the side facing away from the bearing ring (6) has an end face (19) that is located opposite an axial stop (20) on the first or second machine part (10, 11).
