    摘要： The carbon brushes (5), arranged in the housing (6) are pressed in a radial direction against the outer surface of a cylindrical collector (4), fixed to the rotor shaft (2) of the motor, by means of a spring force (7). The housing (6) for the carbon brushes (5) may be removed form the motor with little effort, whereby means (11, 12), which protect the rotating bearing (3) of the rotor shaft (2) against the ingress of dirt with one or several bevels (14, 15), are provided on the side thereof facing the housing (6) with the carbon brushes (5), such that the carbon brushes (5) slide along the above on withdrawal of the housing (6) and are thus pressed radially outwards against the spring force (7).

    摘要： The invention relates to a machine tool, especially a diamond drill. Said machine tool comprises a rotatably driven spindle (11) having an end section (111) supporting an external thread (14), a tool (12), especially a drill bit, having a hollow-cylindrical tool shank (16) with an interior thread (15), to be screwed onto the spindle end section (111), and a release device (13) disposed between the tool shank (16) and the spindle (11). For an easy handling of the release device (13) without tools, the release device is captivated to the spindle (11) and comprises a supporting ring (21) fastened on the spindle (11), and a supporting ring (22) seated on the spindle (11) at a distance from the first supporting ring and being axially displaceable to a limited extent. Said supporting ring is fastened on the other supporting ring (21) in a rotationally fixed manner and is supported on a face of the tool shank (16). A manually rotatable selector ring (23) engages between the supporting rings (21, 22) and allows to change the clearance between the supporting rings (21, 22).

    摘要： 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).

    摘要翻译： 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）。
