Abstract

Die Erfindung geht aus von einer Handwerkzeugmaschine (10), insbesondere einem Bohr- und/oder Meißelhammer (10'), mit einer Loslagervorrichtung (50) für eine Getriebevorrichtung (32), bestehend aus zumindest einem in einer Lagerbuchse (60) mit axialem Schiebesitz angeordneten Wälzlager (54), das zur drehbaren Lagerung einer Welle (46), insbesondere einer Ankerwelle (46'), vorgesehen ist und dazu zumindest einen Außenring (56) und einen Innenring (58) umfasst, wobei der Innenring (58) drehfest mit der Welle (46) verbunden ist. Es wird vorgeschlagen, dass ein aus einem Elastomer-Kunststoffmaterial gefertigter Ring (66) zu einer Abdichtung des zumindest einen Wälzlagers (54) in der Lagerbuchse (60) und einer Vorspannung des zumindest einen Wälzlagers (54) in axialer Richtung (52) und einer Verdrehsicherung und/oder Fixierung des Außenrings (56) des zumindest einen Wälzlagers (54) dient. Vorzugsweise ist der Ring (66) eine aus zumindest drei Lippen (68) bestehende, rotationssymmetrische Dichtung mit im Wesentlichen dreieckigen oder trapezförmigen Querschnittsprofil (70).
