    • The invention relates to a gearing mechanism (1) that serves particularly as a worm gear for assemblies for outside force activated adjustment of elements of a motor vehicle, comprising a housing component (9) and a shaft (2) mounted in the housing component (9). The shaft (2) is driven rotating relative to the housing component (9) with regard to a rotation axis (8) in a first rotation direction (11) and in a second rotation direction (12) opposite the first rotation direction (11). There is also a wrap element (15) that wraps the shaft (2) multiple times. The wrap element (15) is designed as a spring-elastic wrap element (15). A first end (19) of the wrap element (15) is fastened in a stationary manner to the housing component (9). This can achieve a self-locking of the shaft (2) dependent on the rotation direction. It is also possible that an inward oriented friction surface (31) is provided and that the wrap element (15) is arranged within the inward oriented friction surface (31) at least in sections in order to interact with the friction surface (31). This can likewise achieve a self-locking of the shaft (2) dependent on the rotation direction. There is another design variant in that a brake element (41) is provided, the shaft (2) comprises a brake element receptacle (42) that at least partially accommodates the brake element (41) and a contact surface (43) is allocated to the brake element (41) for interacting with the brake element (41). A rotation direction independent self-locking of the shaft (2) can be likewise thus attained by the interaction of the brake element (41) with the contact surface (43).
    • 本发明涉及一种齿轮传动机构(1),该传动机构尤其用作用于机动车元件的外力致动调节的组件的蜗轮,该蜗轮传动机构包括壳体部件(9)和安装在壳体部件(2)中的轴 9)。 轴(2)相对于壳体部件(9)相对于旋转轴线(8)沿第一旋转方向(11)和与第一旋转方向(11)相反的第二旋转方向(12)被驱动旋转, 。 还有多次包裹轴(2)的包裹元件(15)。 包裹元件(15)被设计为具有弹性的包裹元件(15)。 缠绕元件(15)的第一端(19)以固定的方式固定在壳体部件(9)上。 这可以根据旋转方向实现轴(2)的自锁。 也可能的是,提供向内取向的摩擦表面(31),并且缠绕元件(15)至少部分地布置在向内取向的摩擦表面(31)内以便与摩擦表面(31)相互作用。 这同样可以根据旋转方向实现轴(2)的自锁。 另一个设计变体在于,设置有制动元件(41),轴(2)包括至少部分地容纳制动元件(41)的制动元件容纳部(42),并且接触表面(43)被分配给 所述制动元件(41)用于与所述制动元件(41)相互作用。 通过制动元件(41)与接触表面(43)的相互作用同样可以实现轴(2)的旋转方向独立自锁。

    • Gearbox drive unit (10) and a method for producing a gearbox drive unit (10), having an electrical drive motor (12) with an armature shaft (22), and having a gearbox (14), in particular a worm gearbox, arranged downstream from it, which gearbox (14) is operatively connected to the drive motor (12) via the armature shaft (22), and with at least one of the end faces (28) of the armature shaft (22) resting via a starting element (32) on a housing part (16), in which case the starting element (32) can be mounted in the housing part (16) radially with respect to the armature shaft (22), and in which case the starting element (32) is secured against radial movement by means of a separately formed attachment element (33).
    • 齿轮驱动单元(10)具有电动驱动马达(12),其包括电枢轴(22)和齿轮即蜗轮,其布置在驱动马达的下游。 齿轮与驱动电机有效地连接在轴上。 轴位于位于轴的前侧(28)上的触摸盘(32)上的壳体部分(16)。 接触盘径向地安装在壳体部分中的电枢轴上。 接触盘使用单独形成的紧固单元(33)来抵抗径向移动。 紧固单元形成为弹簧垫圈(34)并且可径向安装。 还包括用于制造齿轮驱动单元的方法的独立权利要求。
