Description
Mehrreihige Wälzlagerdrehverbindung mit Antriebsverzahnung Die Erfindung betrifft Wälzlagerdrehverbindungen mit mehreren Wälzkörperreihen zwischen einem einteiligen inneren oder äußeren Lagerring und einem diesen u-förmig umgreifenden, mehrteiligen äußeren oder inneren Lagerring, der mit einem Zahnkranz £tir den Eingriff eines Antriebszahnrades versehen ist.Multi-row rolling bearing rotary connection with drive toothing The invention relates to rolling bearing slewing rings with several rows of rolling elements between one one-piece inner or outer bearing ring and a U-shaped encompassing, multi-part outer or inner bearing ring, which engages with a ring gear £ tir a drive gear is provided.
Derartige Wälzlagerdrehverbindungen dienen der dreh-oder schwenkbaren Lagerung von Baggern, Kränen od. dgl., wobei sie Axialkräfte, Radialkräfte und Kippmomente aufzunehmen haben.Such rolling bearing rotary connections are used to rotate or pivot Storage of excavators, cranes or the like, where they have axial forces, radial forces and overturning moments have to include.
Es ist bekannt, den das zu drehende oder zu schwenkende Gerät tragenden Lagerring mit einem Zahnkranz zu versehen, der sich, sofern er dem mehrteiligen Lagerring zugeordnet ist, nur Jeweils über einen Ringteil dieses Lagerringes erstreckt, Das zu übertragende Drehmoment erfordert in vielen Fällen eine große Zahnbreite, die es erforderlich macht, dem betreffenden Lagerring oder Ringteil eine größere Höhe zu geben, als es von der Lagerkonstruktion her notwendig ist. Dies verursacht größeres Gewicht und höhere Kosten.It is known to carry the device to be rotated or pivoted To provide bearing ring with a ring gear, if it is the multi-part Bearing ring is assigned, extends only over a ring part of this bearing ring, In many cases, the torque to be transmitted requires a large face width, which makes it necessary to give the bearing ring or ring part in question a larger one To give height than it is necessary from the bearing construction. This causes greater weight and cost.
Aufgabe der Erfindung ist es, eine große Zahnbreite ohne größeren baulichen Aufwand zu erreichen. Die Lösung dieser Aufgabe besteht darin, daß der Zahnkranz dem ohnehin höher bauenden mehrteiligen Lagerring zugeordnet wird und ein in Umfangsrichtung geteilter Zahnkranz sich in der Höhe über mehrere Ringteile dieses Lagorrlngos erstreckt. Gemäß einer bevorzugten Ausführung besteht der Lagerring aus zwei starr miteinander verbundenen Ringen, von denen Jeder wenigstens eine Wälzkörper-Laufbahn aufweist und am Umfang mit einem Zalinkrans versehen ist.The object of the invention is to provide a large tooth width without a larger one to achieve structural effort. The solution to this problem is that the The ring gear is assigned to the multi-part bearing ring, which is already higher, and a ring gear divided in the circumferential direction extends in height over several ring parts this Lagorrlngos extends. According to a preferred embodiment, there is the bearing ring of two rigidly interconnected rings, each of which has at least one rolling element raceway and is provided with a zinc crane on the circumference.
Der mehrteilige Lagerring kann der äußere oder der innere Lagerring der vgrtikalachsigen Wälzlagerdrehverbindung sein. Eine bevorzugte Ausführung sieht vor, daß der mehrteilige Lagerring den Außenring der Wälzlagerdrehverbindung bildet und an seinem Umfang den geteilten Zahnkranz aufweist.The multi-part bearing ring can be the outer or the inner bearing ring be the vertical axis roller bearing slewing ring. A preferred embodiment sees before that the multi-part bearing ring forms the outer ring of the rolling bearing rotary connection and has the split ring gear on its circumference.
Das bevorzugte Ausführungebeispiel einer Wälzlagerdrehverbindung ist in der Zeichnung in einem Teilaxialschnitt veranschaulicht.The preferred embodiment of a rolling bearing rotary connection is illustrated in the drawing in a partial axial section.
Der innere Ring 1 des vertikalchsigen, mittenfreien Rollendrehkranzes weist zwei nach der Lagerachse hin durch Borde begrenzte Laufbahnen 2 und 3 für die beiden, die Axial- und Kippmomente aufnehmenden Zylinderrollenreihen 4 und 5 auf. Eine weitere Rollenlaufbahn 6, für eine Radialmomente aufnehmende Rollenreihe 7, befindet sich am Umfang des Ringes 1. Der Ring 1 ist mit einer Anzahl Axialbohrungen 8 für die Aufnahme von zu seiner Befestigung am Fahrgestell od. dgl. dienenden Bolzen versehen.The inner ring 1 of the vertical axis, center-free roller slewing ring has two raceways 2 and 3 for the bearing axis bounded by ribs the two rows of cylindrical rollers 4 and 5 absorbing the axial and tilting moments on. Another roller track 6, for a row of rollers absorbing radial moments 7, is located on the circumference of the ring 1. The ring 1 has a number of axial bores 8 for the inclusion of od for its attachment to the chassis. Like. Serving bolts Mistake.
Der äußere Lagerring ist in der Ebene der oberen Rollenlaufbahn 2 geteilt, d.h., er besteht aus den beiden Ringen 10 und 11, die durch mehrere, über den Umfang verteilte Schaftschrauben 12 starr miteinander sind. Der obere Ring 10 übergreift den inneren Ring 1 und trägt die Gegenlaufbahn 13 für die Rollenreihe 4, während der untere Ring 11 die Gegenlaufbahn 14 für die Rollenreih. 5 trägt. Der untere Ring 11 trägt außerdem noch die Gegenlaufbahn 15 für die Rollenreihe 7.The outer bearing ring is in the plane of the upper roller track 2 divided, i.e. it consists of the two rings 10 and 11, which are connected by several, over the circumference distributed set screws 12 are rigid with one another. The top ring 10 engages over the inner ring 1 and carries the mating track 13 for the row of rollers 4, while the lower ring 11 is the mating track 14 for the row of rollers. 5 carries. The lower ring 11 also carries the mating track 15 for the row of rollers 7th
Die beiden über die Ringflächen 16 zentrierten Ringe 10 und 11 sind mit fluchtenden Axialbohrungen 17 und 18 zur Aufnahme der Befestigungsbolzen für das zu lagernde Gerät versehen und weisen an ihrem Umfang tilungs-und zahnformmäßig übereinstimmende Zahnkränze 19 und 20 auf, die einen in Ümfangsrichtung geteilten, durchgehenden Zahnkranz für den Eingriff eines sich über beide Zahnkränze 19 und 20 erstreckenden Antriebszahnrades bilden.The two rings 10 and 11 centered over the annular surfaces 16 are with aligned axial bores 17 and 18 to accommodate the fastening bolts for the device to be stored is provided and has its circumference in terms of division and tooth shape matching sprockets 19 and 20, which have a split in the circumferential direction, continuous ring gear for the engagement of one over both ring gears 19 and Form 20 extending drive gear.
