Abstract
Description
Die Erfindung geht aus von einer Schmiereinrichtung für ein Getriebe, vorzugsweise in einer Handwerkzeugmaschine, z. B. einem Winkelschleifer, der im Oberbegriff des Anspruchs 1 definierten Gattung.The invention is based on one Lubrication device for a gear, preferably in a hand machine tool, e.g. B. an angle grinder, the type defined in the preamble of claim 1.
Bei einer bekannten Handwerkzeugmaschine in Form eines Winkelschleifers gemäß WO 02/06006 ist das Getriebe mit einer zugeordneten Rückfördereinrichtung für das dort verwendete Schmiermittel, z. B. Fett, versehen, die mindestens ein mit dem Tellerrad dieses Getriebes umlaufendes Förderelement aufweist, das aus mindestens einem radial über die äußere Umfangsfläche des Tellerrades überstehenden Vorsprung gebildet ist, der eine Schrägfläche aufweist, die entgegen der Umlaufrichtung des Tellerrades von dessen Unterseite zur Oberseite schräg ansteigt. Dadurch wird mit einfachen kostengünstigen Mitteln die Schmierung des Getriebes verbessert, weil die Zahnflanken der Zahnräder besser mit Schmierstoff benetzt werden, wobei ein Schmierstoffverlust durch Hindurchsickern des Schmiermittels zwischen dem Rand des Tellerrades und dem Gehäuse vermieden wird. Die Verbesserung der Schmierung führt zu höherer Getriebelebensdauer und Geräuschreduzierung. Dieser Vorteil ergibt sich vor allem bei bisher üblichen zähflüssigen bis pastösen Schmiermitteln, stellt sich aber kaum bei anderen Öl-Schmiersystemen ein, bei denen das Schmiermittel eine geringere Viskosität hat.In a known hand machine tool the gear is in the form of an angle grinder according to WO 02/06006 with an associated return conveyor for the Lubricants used there, e.g. B. fat, provided at least one with the ring gear of this gear revolving conveyor element that at least one radially over the outer peripheral surface of the Ring gears protruding Projection is formed, which has an inclined surface, the opposite the direction of rotation of the ring gear from the bottom to the top aslant increases. Lubrication is thus possible with simple, inexpensive means of the gearbox improved because the tooth flanks of the gears are better be wetted with lubricant, with a loss of lubricant through Leakage of the lubricant between the rim of the ring gear and the housing is avoided. Improving lubrication leads to longer transmission life and noise reduction. This advantage arises above all in the case of viscous to pasty lubricants customary to date, but hardly occurs with other oil lubrication systems which the lubricant has a lower viscosity.
Aus
Die erfindungsgemäße Schmiereinrichtung für ein Getriebe, vorzugsweise in einer Handwerkzeugmaschine, mit den Merkmalen im Anspruch 1 hat demgegenüber den Vorteil, dass über den Schmiermittelkanal das zurückgeführte Schmiermittel auf der Höhe des Eingriffsbereichs der Getrieberäder mit geringem Abstand vor diesem Eingriffsbereich und derart zugeführt wird, dass beide Getrieberäder mit Schmiermittel beaufschlagt werden, welches aufgrund des Zahneingriffs der Getrieberäder im Bereich der in Eingriff stehenden Zahnflanken einen breitflächigen Schmierfilm ergibt. Dadurch wird die Reibung im Eingriffsbereich der Getrieberäder reduziert, wobei eine Geräuschminderung erreicht wird. Die reduzierte Reibung führt zu geringerem Verschleiss und zu höheren Standzeiten. Die erreichte direkte, gezielte Schmiermittelversorgung an der benötigten Stelle hat zugleich eine bessere Kühlung und damit einen weicheren Lauf einer mit einem solchen Getriebe ausgestatteten Handwerkzeugmaschine zur Folge.The lubrication device according to the invention for a transmission, preferably in a hand machine tool, with the features in In contrast, claim 1 has the advantage of that over the returned lubricant at the height the area of engagement of the gear wheels with a small distance this engagement area and is fed such that both gears with Lubricants are applied, which due to the tooth mesh the gear wheels in Area of the meshing tooth flanks with a wide-area lubricating film results. This reduces the friction in the meshing area of the gear wheels, being a noise reduction is achieved. The reduced friction leads to less wear and to higher ones Life. The direct, targeted supply of lubricant achieved at the required The place has better cooling and therefore a softer one Run a hand tool equipped with such a gear result.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Schmiereinrichtung möglich.By the measures listed in the other claims are advantageous developments and improvements in the claim 1 specified lubrication device possible.
