Abstract: A gear drive assembly includes an elongated housing with a cavity and a pair of opposed apertures in communication with the cavity. At least one output shaft extends through the apertures. A drive gear is positioned in the cavity and fixedly connected to the at least one output shaft for rotation therewith. The drive gear and the output shaft have a predefined range of travel in a direction of the longitudinal axis to facilitate assembly of the gear drive assembly. A spacer is located within the cavity between the housing and the drive gear and is configured to preclude movement of the drive gear and the output shaft through the predefined range of travel after assembly. A drive motor can be mounted on the housing for transferring power to the at least one output shaft. A bearing and seal assembly is mounted in the housing around the drive shaft of the drive motor and an axial spacer is located between the drive motor and the bearing and seal assembly to thereby prevent movement of the bearing and seal assembly. A variable length mount can be located at a longitudinal end of the housing. The mount may be shortened to accommodate various mounting criteria of a vehicle.

Abstract translation: 齿轮驱动组件包括具有空腔的细长壳体和与空腔连通的一对相对的孔。 至少一个输出轴延伸穿过孔。 驱动齿轮定位在腔体中并且固定地连接到至少一个输出轴以与其一起旋转。 驱动齿轮和输出轴具有在纵向轴线的方向上的预定行程范围，以便于齿轮传动组件的组装。 间隔件位于壳体和驱动齿轮之间的腔内，并且构造成在组装之后阻止驱动齿轮和输出轴通过预定行程范围的运动。 驱动马达可以安装在壳体上，用于将动力传递到至少一个输出轴。 轴承和密封组件围绕驱动马达的驱动轴安装在壳体中，并且轴向间隔件位于驱动马达与轴承和密封组件之间，从而防止轴承和密封组件的移动。 可变长度的安装件可以位于壳体的纵向端部。 可以缩短安装座以适应车辆的各种安装标准。
