Abstract
Die vorliegende Erfindung stellt ein Haltegestell (1) für Wellenlager bereit, welches mit Öffnungen (10) ausgestattet ist, welche der Anzahl der Walzenkörper (20) entsprechen, um für die zwischen den inneren und äußeren Scheiben bewegten Walzenkörper (20) Verwendung zu finden. An der Innenfläche mit Kontakt zu den Walzenkörpern (20) ist an jeder Öffnung (10) des vorstehend bezeichneten Haltegestells (1) eine Einbuchtungsrille oder Höhle (13) zur Speicherung von Schmierfett ausgebildet. Dieses Haltegestell vermag zu gewährleisten, dass zumindest ein Teil des Schmierfetts ständig in dessen Einbuchtungsrille oder Höhle verbleibt, was sich positiv bezüglich des Problems einer nicht ausreichenden Schmierung zwischen den Walzenkörpern und dem Haltegestell in der Startphase des Elektromotors auswirkt. Auf der Basis des vorstehend bezeichneten Haltegestells stellt die vorliegende Erfindung außerdem verschiedene übliche Walzenwellenlager mit Verwendung des betreffenden Wellenlagers bereit.The present invention provides a shaft bearing support frame (1) provided with openings (10) corresponding to the number of roller bodies (20) for use with the roller bodies (20) moved between the inner and outer disks. On the inner surface in contact with the roller bodies (20), a recessed groove or cavity (13) for storing grease is formed on each opening (10) of the above-described support frame (1). This support frame is able to ensure that at least a portion of the grease constantly remains in the indentation groove or cavity, which has a positive effect on the problem of insufficient lubrication between the roller bodies and the support frame in the starting phase of the electric motor. On the basis of the above-described support frame, the present invention also provides various conventional roller shaft bearings using the respective shaft bearing.
Description
Technisches Gebiet Technical area
Die vorliegende Erfindung betrifft ein Haltegestell für Wellenlager zur Verwendung für Walzenwellenlager verschiedener konventioneller Arten. The present invention relates to a shaft bearing support frame for use with roller shaft bearings of various conventional types.
Stand der Technik State of the art
Bei Anwendungen für Hochgeschwindigkeitszüge besteht für die Wellenlager der Zugelektromotoren eine Tendenz zur Verwendung von Fettschmierung. Der Grund hierfür ist, dass in schwieriger Anwendungsumgebung im Falle der Verwendung eines Systems mit Ölschmierung sehr leicht Fremdmaterialien eindringen können, was zu einer signifikanten Verkürzung der Lebensdauer der Wellenlager führt. Allerdings weist die Fettschmierung an sich ebenfalls Probleme auf, beispielsweise die relativ hohe Viskosität, was eine Einführung in die Öffnungen (cage pockets) der Haltegestelle schwierig gestaltet. Daher führt eine Umrüstung auf Fettschmierung in der Startphase leicht zu einer nicht ausreichenden Schmierung zwischen den Walzenantriebskörpern und der Halterung mit der Folge von Verschleiß der Teile und einer Verkürzung der Lebensdauer der Wellenlager. In high speed train applications, the shaft bearings of traction electric motors tend to use grease lubrication. The reason for this is that, in a difficult application environment, when using a system with oil lubrication, foreign matters can easily penetrate, resulting in a significant shortening of the life of the shaft bearings. However, the grease lubrication itself also has problems, such as the relatively high viscosity, which makes it difficult to introduce into the cage pockets of the holding racks. Therefore, conversion to grease lubrication in the starting phase easily leads to insufficient lubrication between the roller drive bodies and the holder, resulting in wear of the parts and a shortening of the life of the shaft bearings.
Inhalt der Erfindung Content of the invention
Zwecks Lösung der vorstehend aufgeführten Probleme stellt die vorliegende Erfindung ein Haltegestell für Wellenlager bereit. Das betreffende Wellenlager ist mit Öffnungen ausgestattet, welche der Anzahl der Walzenkörper entsprechen, um für zwischen den inneren und äußeren Scheiben bewegte Walzenkörper Verwendung zu finden. An der Innenfläche mit Kontakt zu den Walzenkörpern ist an jeder Öffnung eine Einbuchtungsrille oder Höhle zur Speicherung von Schmierfett ausgebildet. Auf der Basis des vorstehend bezeichneten Haltegestells stellt die vorliegende Erfindung außerdem verschiedene konventionelle Walzenwellenlager mit Verwendung des betreffenden Wellenlagers bereit. In order to solve the above problems, the present invention provides a shaft bearing support frame. The shaft bearing concerned is provided with openings which correspond to the number of roller bodies in order to find use for roller bodies moved between the inner and outer disks. On the inner surface in contact with the roll bodies, a recessed groove or cavity for storing grease is formed at each opening. On the basis of the above-described support frame, the present invention also provides various conventional roller shaft bearings using the shaft bearing concerned.
Das vorstehend bezeichnete Haltegestell kann gewährleisten, dass zumindest ein Teil des Schmierfetts ständig in dessen Einbuchtungsrille oder Höhle verbleibt, was sich positiv bezüglich des Problems einer nicht ausreichenden Schmierung zwischen den Walzenkörpern und dem Haltegestell in der Startphase des Elektromotors auswirkt. The above-described support frame can ensure that at least a portion of the grease remains permanently in the indentation groove or cavity, which has a positive effect on the problem of insufficient lubrication between the roller bodies and the support frame in the starting phase of the electric motor.
