Abstract
(DE)
Die Erfindung geht aus von einer Werkzeugmaschine, insbesondere von einem handgeführten Bohrhammer, mit einem Raum (10) mit Schmiermittel und einer Druckausgleichseinrichtung (12, 14, 34) des Raums (10) im Bereich eines Lagers (16, 18, 36) eines rotierend antreibbaren Bauteils (20, 22, 54). Es wird vorgeschlagen, daß das Lager (16, 18, 36) zumindest einen Teil einer Schmiermitteldichtung (24, 26, 38) der Druckausgleichseinrichtung (12, 14, 34) bildet, über die ein Druck im Raum (10) ausgleichbar ist.
(EN)
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.
(FR)
La présente invention concerne une machine outil, notamment un marteau perforateur manuel, comprenant une chambre (10) à lubrifiant et un dispositif de compensation de pression (12, 14, 34), qui est destiné à la chambre (10) et se trouve dans la zone d'un support (16, 18, 36) pour un composant pouvant être entraîné en rotation (20, 22, 54). Selon cette invention, le support (16, 18, 36) constitue au moins une partie d'un joint à lubrifiant (24, 26, 38) du dispositif de compensation de pression (12, 14, 34), qui permet de compenser une pression dans la chambre (10).
