    摘要: The invention relates to a machine tool, in particular a hand-operated hammer drill, comprising a chamber (10) with lubricating agent and a pressure equalising device (12, 14, 34) for the chamber (10), in the region of a bearing (16, 18, 36) for a rotating driven component (20, 22, 54). According to the invention, the bearing (16, 18, 36) forms at least part of a lubricating agent seal (24, 26, 38) for the pressure equalisation device (12, 14, 34), by means of which a pressure in the chamber (10) may be equilibrated.

    摘要: The invention relates to a machine tool, in particular a hand-operated hammer drill, comprising a chamber (10) with lubricating agent, inside which at least one rotating driven component (12) is arranged, and a pressure equalisation device (14) for the chamber (10), with a rotating driven spinning component (16), screening a pressure equalisation channel (18) arranged downstream from the above, in relation to the flow in the ventilating direction. According to the invention the spinning component (16) is fixed to the rotating driven component (12).

    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).
