Description
Wälzlagerung Bisher bekannte Kegeltriebe, bestehend aus zwei winkelig zueinander angeordneten Wellen und zwei miteinander im Eingriff befindlichen Ritzeln müssen axial eingestellt und fixiert werden. Zur Aufnahme von Axial.- und Radialkräften sind die beiden Wellen in jeweils einem Fest- und einem Ioslager gelagert, damit Fertigungstoleranzen und Wärmedehnung ausgeglichen werden können. Der Außenring des Festlagersist mit zwei Sprengringen im Gehäuse gesichert, während sich der Innenring einerseits an einem Wellenbund abstützt und andererseits mittels Paßscheiben und Nutmutter gehalten ist. Das Einstellen der Kegelritzel erfolgt'durch Hinzufügen oder Wegnehmen von Paßseheiben.Rolling bearings Previously known bevel drives, consisting of two angled mutually arranged shafts and two mutually engaged pinions must be adjusted and fixed axially. For absorbing axial and radial forces the two shafts are each stored in a fixed and an Ioslager, so Manufacturing tolerances and thermal expansion can be compensated. The outer ring of the fixed bearing is secured with two snap rings in the housing, while the inner ring supported on the one hand on a shaft collar and on the other hand by means of shims and Locknut is held. The bevel pinions are set by adding or removing passports.
Der Erfindung liegt die Aufgabe zugrunde die axiale Einstellbarkeit der Wälzlager so zu verbessern, dafl die Kegelritzel einfach und genau und ohne Verwendung-von Paßscheiben verschiedener Dicke festgelegt werden können.The invention is based on the object of axial adjustability To improve the rolling bearings so that the bevel pinions are simple and precise and without Use-of shims of different thicknesses can be set.
Nach der Erfindung ist zum axialen Einstellen und Fixieren des Wälzlagers ein mit Gewinde versehner Laufring vorgesehen.-Ein weiteres Merkmal der Erfindung besteht darin,. daß der, mit Gewinde versehene und eingestellte Laufring durch ein aushärtendes Bindemittel gesichert ist.According to the invention is for the axial setting and fixing of the roller bearing a threaded raceway is provided. Another feature of the invention consists in. that the, threaded and adjusted race through a hardening Binder is secured.
Das Wälzlager nach der Erfindung ermöglicht eine sehr feine,-stufenlose Axialeinstellung, die schnell und sicher vorgenommen werden kann Die Zeichnung stellt im Schnitt einen Kegeltrieb als Ausführungsbeispiel der Erfindung dar.The roller bearing according to the invention enables a very fine, stepless Axial adjustment that can be made quickly and safely The drawing represents shows in section a bevel drive as an embodiment of the invention.
Dei beiden Wellen 1 und 2 sind mit den Kegelritzeln 3 bzw- 4 fest verbunden Die Welle 1 stützt sich über ein Loslager 5 und ein Festlager 6, die Welle 2 über ein Ioslager 7 und ein Festlager 8 im Gehäuse ab. Der Außen-Laufring 9'des Wälzlagers 6 ist mit Gewinde 10 versehen und in ein entsprechendes Gegenges winde des Gehäuses 11 eingeschraubt. Der Innen-Laufring 12 stützt sich einerseits an einer Buchse 13 und andererseits an einem Bund 14 der Welle 1 ab Das Festlager B der Welle 2 weist am Innen-Laufring 15 Gewinde 16 auf, mit dem der Innen-Laufring 15 auf das Gegengewinde der Welle 2 aufgeschraubt ist. Der Außen-Iaufring 17 wird durch Abstandsringe.18, 19 und einen Sprengring 20 im Gehäuse festgehalten Der jeweils mit Gewinde- versehene Außen- oder Innen-Laufring 9 bzwo 15 weist zum Einschrauben Nuten 21 bzwe 22 auf. Die Sicherung gegen Verdrehen des mit Gewinde versehenen Innen- oder Außen-Laufringes kann mechanisch oder durch ein aushärtendes Bindemittel vorgenommen werden.The two shafts 1 and 2 are firmly connected to the bevel pinions 3 and 4, respectively. The shaft 1 is supported by a floating bearing 5 and a fixed bearing 6, while the shaft 2 is supported by a floating bearing 7 and a fixed bearing 8 in the housing. The outer race 9 ′ of the roller bearing 6 is provided with a thread 10 and screwed into a corresponding mating thread of the housing 11. The inner race 12 is supported on the one hand on a bush 13 and on the other hand on a collar 14 of the shaft 1. The fixed bearing B of the shaft 2 has threads 16 on the inner race 15, with which the inner race 15 fits onto the mating thread of the shaft 2 is screwed on. The outer running ring 17 is held in place in the housing by spacer rings 18, 19 and a snap ring 20. The outer or inner running ring 9 or 15 , which is provided with a thread, has grooves 21 or 22 for screwing in. Securing against twisting of the threaded inner or outer race can be done mechanically or by a hardening binding agent.
Aus Gründen der einfacheren Herstellung und Lagerhaltung, können auch nur die Außen-Laufringe der beiden Festlager 6, 8 mit Gewinde versehen sein.For the sake of easier manufacture and storage, you can also only the outer races of the two fixed bearings 6, 8 can be provided with threads.
Durch-Verdrehen der Gewinde-Laufringe mit einem Spezial-Schlüssel, wird das gewünschte Verzahnungsspiel zwischen-den Kegelritzeln eingestellt.By turning the thread race rings with a special key, the desired backlash between the bevel pinions is set.
