    • The invention relates to an electric hand tool, which comprises a drive gear (15) that is located in a housing (10) with a gear shaft (20), in addition to at least one radial bearing (30) for rotatably bearing the gear shaft (20). The inner bearing ring (301) of the radial bearing is fixed on the gear shaft (20) so that it cannot be axially displaced and the outer bearing ring (302) is also fixed in a bearing bush (31) in the housing (10) so that it cannot be axially displaced. To facilitate the simple mounting of the drive gear (15) without the need for tools, the outer bearing ring (302) of the radial bearing (30) lies in the bearing bush (31) in a push fit and is fixed by means of a clip (32) that is attached to the bearing bush (31).
    • 本发明涉及一种电动手持工具,其除了至少一个用于可旋转地支承齿轮(10)的径向轴承(30)之外还包括位于具有齿轮轴(20)的壳体(10)中的驱动齿轮(15) 轴(20)。 径向轴承的内轴承环(301)固定在齿轮轴(20)上,使得其不能轴向移动,并且外轴承环(302)也固定在壳体(10)中的轴承衬套(31) ),因此它不能轴向移动。 为了便于在不需要工具的情况下简单地安装驱动齿轮(15),径向轴承(30)的外轴承环(302)以推入配合的方式位于轴承衬套(31)中并且通过 夹在轴承衬套(31)上的夹子(32)。
