Abstract: A hand-held power tool is provided that includes a housing, a motive source, a front endbell, an output shaft, a front housing, and a gear set assembly. The output shaft protrudes from an output end at the front endbell of the housing. The output shaft is also functionally coupled to the motive source such that the output shaft rotates in response to activation of the motive source when the motive source is supplied with power. The gear set assembly is located in an interior space of the front housing, and is configured to transfer rotation from the motive source to an output spindle. The gear set assembly also includes a ring gear that surrounds a portion of the output shaft and abuts the front endbell of the housing. A set of piloting features is provided that is configured to prevent movement of the ring gear relative to the motive source and the front housing, or the front housing relative to the housing.

Abstract translation: 提供了一种手持式电动工具，其包括壳体，动力源，前端耳环，输出轴，前壳体和齿轮组组件。 输出轴从壳体前端的输出端突出。 输出轴也在功能上耦合到动力源，使得当动力源被供电时，输出轴响应于动力源的启动而旋转。 齿轮组组件位于前壳体的内部空间中，并且构造成将旋转从动力源传递到输出心轴。 齿轮组组件还包括环形齿轮，该齿圈围绕输出轴的一部分并邻接壳体的前端耳。 提供了一组引导特征，其构造成防止环形齿轮相对于动力源和前壳体或前壳体相对于壳体的移动。
