Abstract
Die Erfindung betrifft einen Elektromotor mit einem Gehäuse und einem Rotor, der in dem Gehäuse über eine Fest-/Loslagerung gelagert ist, wobei als Festlager ein Rillenkugellager mit einem Innenring und einem Außenring vorgesehen ist, der Außenring des Festlagers mittels einer Federstahlscheibe im Gehäuse elastisch eingespannt ist. Aufgabe der Erfindung ist es ein Rillenkugellager mit einfachen Mitteln, mit möglichst wenigen Verfahrensschritten und wenigen Bauteilen sicher und dauerhaft in einem tiefgezogenen Stahlgehäuse festzulegen. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The invention relates to an electric motor having a housing and a rotor which is mounted in the housing via a fixed / floating bearing, wherein a deep groove ball bearing with an inner ring and an outer ring is provided as a fixed bearing, the outer ring of the fixed bearing by means of a spring steel disc in the housing elastically clamped is. The object of the invention is to define a deep groove ball bearings with simple means, with as few process steps and few components safely and permanently in a deep-drawn steel housing. This object is achieved by the features of claim 1.
Description
Die Erfindung betrifft einen Elektromotor mit einem Gehäuse und einem Rotor, der in dem Gehäuse über eine Fest-/Loslagerung gelagert ist, wobei als Festlager ein Rillenkugellager mit einem Innenring und einem Außenring vorgesehen ist und der Außenring des Festlagers mittels einer Federstahlscheibe im Gehäuse elastisch eingespannt ist. The invention relates to an electric motor having a housing and a rotor which is mounted in the housing via a fixed / floating bearing, wherein a deep groove ball bearing with an inner ring and an outer ring is provided as a fixed bearing and the outer ring of the fixed bearing by means of a spring steel disc in the housing elastically clamped is.
Die Form der erfindungsgemäßen Federstahlscheibe ist an sich bekannt, insbesondere bei Kalottenlagern werden derartige Bauelemente regelmäßig eingesetzt. Ein wesentlicher Unterschied zur Gattung der Erfindung besteht darin, dass bei Kalottenlagern die Welle axial kein Moment auf das Lager ausübt. Hingegen kann bei einem fest mit der Welle verpressten Innenring eines Rillenkugellagers eine große axiale Last auf das Lager übertragen werden, insbesondere bei Vibrations- und Stoßbelastung. The shape of the spring steel disc according to the invention is known per se, especially in spherical bearings such components are used regularly. An essential difference to the genus of the invention is that with spherical bearings, the shaft exerts no axial moment on the bearing. By contrast, a large axial load can be transmitted to the bearing in a firmly pressed with the shaft inner ring of a deep groove ball bearing, especially in vibration and shock load.
