Abstract

The shaft (8) is located between two shaft bearings (10) and has a brake ring (5) rotating with the shaft. The brake ring is attached to the shaft by a spring layer (7) and is located inside a brake housing. The brake ring (4) has a multilayer construction with a brake layer (3) pressed against the brake ring (5) by a hydraulic chamber between two hydraulic seals (6) and mounted in a support ring (2). The brake system is located in the brake housing by pins (11,12). A variation in the design has the hydraulic brake pressure applied via hydraulic ducts through the shaft, and with the brake ring (5) pressed against outwards against the brake layer.

Description

In üblicher Weise wird eine Wälzlagerung durch einen inneren und äußeren Distanzring, die entsprechend aufeinander abgestimmt wurden, vorgespannt. Als Klemmung der Wellen dienen mechanische, pneumatische und elektromagnetische Bauelemente unabhängig der Lagerung. Diese Lösungen sind einerseits sehr kosteninten­ siv, andererseits nur mit höherem Platzbedarf und Aufwand zu realisieren.In the usual way, a roller bearing is made up of an inner and outer spacer ring, which have been coordinated accordingly. Mechanical, pneumatic and electromagnetic are used to clamp the shafts Components regardless of storage. On the one hand, these solutions are very expensive siv, on the other hand, can only be realized with a higher space requirement and effort.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine hy­ draulische Klemmeinrichtung 13 für walzgelagerte Wellen 8 zu schaffen, die es ermöglicht mit dem äußeren Distanzring 4, der in seiner Bauart als hydraulische Einheit ausgebildet ist, Wellen 8 radial und axial zu klemmen.The invention specified in protection claim 1 is based on the problem of creating a hy draulic clamping device 13 for roller-mounted shafts 8 , which makes it possible to clamp shafts 8 radially and axially with the outer spacer ring 4 , which is designed as a hydraulic unit.

Diese Bauweise erlaubt eine platzsparende kompakte Konstruktion von Maschinenelemen­ ten.This design allows a space-saving, compact construction of machine elements ten.

Einrichtung einer Welle 8 mit vorgespannten Wälzlagern 10 und eingebauter hydraulischer Klemmeinrichtung 13:
Je nach Bedürfnisse und Einsatzfall können mehrere Bauvarianten, wie in den Schutzan­ sprüchen 1, 2, 3 und 4 unterschieden, realisiert werden.Setting up a shaft 8 with preloaded roller bearings 10 and built-in hydraulic clamping device 13 :
Depending on needs and application, several construction variants, as distinguished in protection claims 1, 2, 3 and 4, can be implemented.

Zur Vereinfachung ist im weiteren Typ 1 beschrieben, Typ 2 und 3 systemlogisch gleich­ zusetzen und funktionsmäßig identisch. To simplify matters, type 1 is described below, types 2 and 3 are logically the same add and functionally identical.  

Die hydraulische Klemmeinrichtung 13, wird im Lagerblock 1 zwischen zwei Wälzlager 10 eingebaut und ist durch zwei Zylinderstifte 11 formschlüssig mit dem Lagerblock 1 verbunden.The hydraulic clamping device 13 is installed in the bearing block 1 between two rolling bearings 10 and is positively connected to the bearing block 1 by two cylindrical pins 11 .

Die hydraulische Klemmeinrichtung 13, besteht aus dem äußeren Distanzring 4, der als hy­ draulische Einheit ausgebildet ist und zusätzlich aus dem inneren Distanzring 5.The hydraulic clamping device 13 consists of the outer spacer ring 4 , which is designed as a hy draulic unit, and additionally of the inner spacer ring 5 .

Durch entsprechendes Aufeinanderabstimmen von innerem Distanzring 5 und äußerem Distanzring 4, bzw. durch Anziehen der Vorspannmutter 14 wird die Wälzlagerung in übli­ cher Weise vorgespannt.By correspondingly coordinating the inner spacer ring 5 and outer spacer ring 4 , or by tightening the preload nut 14 , the rolling bearing is preloaded in the usual manner.

Bei der hydraulischen Klemmeinrichtung 13 wirkt der innere Distanzring 5 als Bremsring der Welle 8, welcher über die Paßfeder 7 mit der Welle 8 formschlüssig verbunden ist. Der äußere Distanzring 4 ist eine hydraulische Einheit bestehend aus Außenring 2, Klem­ mring 3 und Dichtungen 6 sowie den Zylinderstiften 12.In the hydraulic clamping device 13, the inner spacer ring 5 acts as a brake ring of the shaft 8 , which is positively connected to the shaft 8 via the parallel key 7 . The outer spacer ring 4 is a hydraulic unit consisting of an outer ring 2 , a clamping ring 3 and seals 6 and the cylinder pins 12 .

Der Außenring 2 und der Klemmring 3 sind durch Zylinderstifte 12 formschlüssig verbun­ den.The outer ring 2 and the clamping ring 3 are positively connected by cylinder pins 12 .

Die hydraulische Klemmeinrichtung 13 ist über den äußeren Distanzring 4 durch zwei Zylinderstifte 11, formschlüssig mit dem Lagerblock 1 verbunden.The hydraulic clamping device 13 is positively connected to the bearing block 1 via the outer spacer ring 4 by two cylindrical pins 11 .

Bei Druckbeaufschlagung verformt sich im äußeren Distanzring 4, der als hydraulische Einheit ausgebildet ist, der Klemmring 3.When pressure is applied, the clamping ring 3 is deformed in the outer spacer ring 4 , which is designed as a hydraulic unit.

Dies führt zu einer kraftschlüssigen Verbindung zwischen dem Klemmring 3 und dem inneren Distanzring 5. Da der innere Distanzring 5 über die Paßfeder 7 mit der Welle 8 fest verbunden ist und somit als Bremsring wirkt, wird diese radial und axial reibschlüssig geklemmt.This leads to a non-positive connection between the clamping ring 3 and the inner spacer ring 5 . Since the inner spacer ring 5 is firmly connected to the shaft 8 via the parallel key 7 and thus acts as a brake ring, the latter is clamped radially and axially by friction.
