Abstract

The drive unit is assembled of a worm gear (1) and a toothed wheel (2) with teeth meshing with the grooves at the worm gear (1). The worm gear (1) is enveloped by a housing (3) in the contact area. The housing (3) is a lubricant chamber with a grease nipple (3a) on top and closed with a lid from above. For assembly the toothed wheel (2) is pushed against the worm gear (1), the lid added, and the unit only once supplied with a lubricant.

Description

Die Erfindung bezieht sich auf eine Schraubradgetriebeeinheit. Schraubradgetriebeeinheiten sind bekannt. Sie bestehen in der Regel aus einer Schnecke, in die ein Schraubrad eingreift. Bei diesen Schraubradgetriebeeinheiten ist es in der Regel erforderlich, die Teile mit Fett zu schmieren. Bei längeren Betriebszeiten wird das Fett jedoch nach außen gedrückt, so dass der Eingriff periodisch nachgeschmiert werden muss, was nachteilig ist.The The invention relates to a helical gear unit. Schraubradgetriebeeinheiten are known. They usually consist of a snail, in which one Clutch wheel engages. In these Schraubradgetriebeeinheiten is It usually requires lubricating the parts with grease. at longer Operating times, however, the fat is pushed outward, so the intervention periodically must be relubricated, which is disadvantageous.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Schraubradgetriebeeinheit zu schaffen, bei der auf das periodische Nachschmieren weitgehend verzichtet werden kann.Of the The invention is therefore based on the object, a Schraubradgetriebeeinheit to create at the periodic relubricating largely can be waived.

Die der Erfindung zugrunde liegende Aufgabe wird durch eine Schraubradgetriebeeinheit gelöst, die aus einer Schnecke und einem Schraubrad besteht, die miteinander im Eingriff stehen, wobei die Schnecke im Bereich des Eingriffes von einer Fettkammer umgeben ist. Die Schraubradgetriebeeinheit kann konstruktiv globoidisch oder nicht globoidisch gestaltet sein. Im Bereich des Eingriffes ist dabei der Teil der Schnecke allseitig von der Fettkammer umschlossen. Die Versorgung des Eingriffes erfolgt dabei über Schmiernippel, die in der Fettkammer angeordnet sind. Es hat sich in überraschender Weise gezeigt, dass bei dieser Schraubradgetriebeeinheit auf ein periodisches Nachschmieren verzichtet werden kann. Dies wird dadurch realisiert, dass die Fettkammer ein Austreten des Fettes aus dem Eingriff verhindert.The The object underlying the invention is achieved by a Schraubradgetriebeeinheit solved that consists of a worm and a helical gear, which together engage, with the worm in the area of engagement surrounded by a fat chamber. The helical gear unit can be structurally globoidisch or not globoidisch designed. in the The area of engagement is the part of the screw on all sides enclosed by the fat chamber. The supply of the procedure takes place over it Grease nipples arranged in the grease chamber. It has in a surprise Ways shown that in this Schraubradgetriebeeinheit on a Periodic relubrication can be dispensed with. This will be done realized that the fat chamber leakage of fat from the Intervention prevented.

Eine bevorzugte Ausgestaltung der Erfindung besteht darin, dass die Fettkammer ein lösbares Deckelteil aufweist, das den Eingriff abdeckt. Auf diese Weise wird das Zusammenfügen von Schnecke und Schraubrad im Bereich der Fettkammer erleichtert, was beispielsweise eine Serienfertigung begünstigt.A preferred embodiment of the invention is that the grease chamber a solvable one Cover part which covers the engagement. This way will the joining together facilitated by worm and helical gear in the area of the grease chamber, which favors, for example, a series production.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Fettkammer einen senkrecht zur Längsachse der Schnecke angeordneten Schmiernippel aufweist. Auf diese Weise lässt sich der Eingriff vor dem Betrieb problemlos mit Fett versorgen, wobei dieses relativ einfach erfolgen kann.According to one further preferred embodiment of the invention is provided the grease chamber is arranged perpendicular to the longitudinal axis of the screw Has grease nipple. In this way, the procedure before the Operate easily with grease, this being relatively easy can.

Die Erfindung wird nachfolgend anhand der Zeichnung (1 bis 3) näher und beispielhaft erläutert.The invention will be described below with reference to the drawing (in which 1 to 3 ) explained in greater detail and by way of example.

1 zeigt die Schraubradgetriebeeinheit dreidimensional ohne Deckelteil. 1 shows the Schraubradgetriebeeinheit three-dimensional without cover part.

2 zeigt die Schraubradgetriebeeinheit dreidimensional mit Deckelteil. 2 shows the Schraubradgetriebeeinheit three-dimensional with lid part.

3 zeigt die Fettkammer mit Decketeil in dreidimensionaler Form. 3 shows the fat chamber with cover part in three-dimensional form.

In 1 ist die Schraubradgetriebeeinheit dreidimensional dargestellt. Sie besteht aus einer Schnecke 1 und einem Schraubrad 2, die miteinander im Eingriff stehen, wobei die Schnecke 1 im Bereich des Eingriffes von einer Fettkammer 3 umgeben ist. Die Fettkammer 3 weist einen senkrecht zur Längsachse der Schnecke 1 angeordneten Schmiernippel 3a auf und lässt sich durch ein Deckelteil (nicht dargestellt) im Bereich des Eingriffes verschließen. Im dargestellten Zustand kann das Schraubrad 2 von oben direkt in die Schnecke 1 eingeschoben werden. Danach erfolgt das Verschließen mit dem lösbaren Deckelteil (nicht dargestellt). Abschließend schließt sich vor der Inbetriebnahme die nahezu einmalige Schmierung an, die mittels des Schmiermittels 3a erfolgt.In 1 the Schraubradgetriebeeinheit is shown in three dimensions. It consists of a snail 1 and a helical wheel 2 which are engaged with each other, the snail 1 in the area of the intervention of a fat chamber 3 is surrounded. The fat chamber 3 has a direction perpendicular to the longitudinal axis of the screw 1 arranged grease nipple 3a and can be closed by a cover part (not shown) in the region of the procedure. In the illustrated state, the helical gear 2 from the top directly into the snail 1 be inserted. Thereafter, the closure with the detachable cover part (not shown). Finally, close to commissioning, the almost unique lubrication, the means of the lubricant 3a he follows.

In 2 ist die Schraubradgetriebeeinheit dreidimensional mit dem lösbaren Deckelteil 3b der Fettkammer 3 dargestellt. In diesem Zustand ist es nicht möglich, dass Fett aus der Schraubradgetriebeeinheit in größerer Menge austreten kann.In 2 the helical gear unit is three-dimensional with the detachable lid part 3b the fat chamber 3 shown. In this state, it is not possible for grease to leak out of the helical gear unit in a larger amount.

In 3 ist die Fettkammer 3 zusammen mit dem lösbaren Deckelteil 3b dreidimensional dargestellt. In diesem Zustand ist sie zur Aufnahme der Schnecke (nicht dargestellt) bereit.In 3 is the fat chamber 3 together with the detachable lid part 3b shown in three dimensions. In this condition it is ready to receive the worm (not shown).
