Abstract

The motor housing, of sheet metal contains two diametrically-opposed permanent magnets (3, 4). At the top of the housing and on its circumference two lugs (5, 6) are formed with holes (7, 8) for fixing a bearing shield. The housing is formed inwards (10, 11), possibly along its whole length, at the positions of the lugs. ADVANTAGE - Fixings for bearing shield produce no appreciable increase in motor housing.

Description

Die Erfindung betrifft einen Elektromotor mit einem Gehäuse, das insbesondere aus einem Blech tiefgezogen ist und an der einen Stirnseite nach außen abstehende Laschen mit Mitteln für die Befestigung eines Lagerschildes vorgesehen sind und zwei sich einander gegenüberliegende Permanentmagnete aufweist.The invention relates to an electric motor with a housing, the is particularly deep drawn from a sheet and on one end outwardly projecting tabs with means for attaching a End shield are provided and two opposite one another Has permanent magnets.

Es sind Gehäuse für Elektromotoren bekannt, die topfförmig sind und einen Rand für die Auflage des Lagerschildes haben. Der Rand hat im Bereich der Polschuhe an zwei Stellen nach außen gerichtete Laschen, die Augen für die Befestigungsschrauben des Lagerschildes aufweisen.Housings for electric motors are known which are cup-shaped and have one Have an edge for supporting the end shield. The edge has in the range of Pole shoes have tabs facing outwards in two places, eyes for the Have mounting screws on the end shield.

Diese nach außen gerichteten Laschen stören in den Fällen, in denen der Platz für den Einbau der Motoren begrenzt ist.These outward-facing tabs interfere in cases where the Space for installing the motors is limited.

Aufgabe der Erfindung ist es, die Befestigung des Lagerschildes am Gehäuse zu ermöglichen, ohne daß der Durchmesser des Randes an den Befestigungsstellen wesentlich vergrößert werden muß.The object of the invention is to attach the end shield to the housing to allow without the diameter of the edge to the Attachment points must be increased significantly.

Erfindungsgemäß wird das dadurch erreicht, daß sich die Laschen in Umfangsrichtung zwischenden Permanentmagneten befinden und das Gehäuse im Bereich der Laschen nach innen verformt ist. Gegenüber der bisherigen Lösung sind also die Laschen um 90° versetzt und nach innen verschoben angeordnet. Dadurch kann die Vergrößerung des Randdurchmessers an dieser Stelle verringert bzw. vermieden werden. Die Mittel für die Befestigung des Lagerschildes können Bohrungen an der Lasche sein.According to the invention this is achieved in that the tabs in Circumferential direction between the permanent magnets and the housing in Area of the tabs is deformed inwards. Compared to the previous solution the tabs are offset by 90 ° and shifted inwards. This can increase the edge diameter at this point be reduced or avoided. The means for attaching the End shield can be holes on the tab.

Sofern die Bohrungen Gewindebohrungen sind, ist die Verformung des Gehäuses nur im Bereich der Stirnseite erforderlich. Insbesondere wenn die Bohrungen als glatte Bohrungen, also als Auge, ausgebildet sind, ist es zweckmäßig, das Gehäuse auf der ganzen Länge nach innen zu verformen, um von dieser Seite die Befestigungsschrauben durch die Augen in Gewindebohrungen des Lagerschildes einführen zu können. If the holes are threaded holes, the deformation of the housing only required in the area of the front. Especially when the holes are designed as smooth bores, i.e. as an eye, it is expedient to deform the case all the way in to get away from this Page the fastening screws through the eyes in threaded holes of the To be able to insert end shield.  

Neben dem genannten Vorteil kann mit der erfindungsgemäßen Lösung auch die Stabilität des Gehäusetopfes und überraschenderweise auch die Geräuscharmut verbessert werden.In addition to the advantage mentioned, the solution according to the invention can also be used Stability of the housing pot and surprisingly also the low noise level be improved.

Die Erfindung soll in einem Ausführungsbeispiel anhand von Zeichnungen erläutert werden. Es zeigen:In one exemplary embodiment, the invention is intended to be based on drawings are explained. Show it:

Fig. 1 den Längsschnitt durch ein Motorengehäuse und Fig. 1 shows the longitudinal section through a motor housing and

Fig. 2 eine Draufsicht auf das Motorengehäuse in axialer Richtung. Fig. 2 is a plan view of the motor housing in the axial direction.

Ein topfförmiges Gehäuse 1 hat einen flanschartigen Rand 2 für die Auflage eines nicht dargestellten Lagerschildes. Im Gehäuse 1 sind Permanentmagnete 3, 4 des Elektromotors angeordnet. Zwischen den Permanentmagneten ist das Gehäuse auf der gesamten Länge nach innen verformt, so daß Einbuchtungen 10, 11 entstanden sind. Im Bereich jeder Einbuchtung 10, 11 befindet sich eine Lasche 5 bzw. 6, die in der Ebene des Randes 2 liegt, eine Verbreiterung des Randes 2 darstellt und eine Durchgangsbohrung 7 bzw. 8 aufweist. Infolge der Einbuchtungen können die Laschen 5, 6 und auch die Bohrungen weiter nach innen verlegt werden, so daß der Flansch an dieser Stelle je nach Stärke der Einbuchtung radial nur geringförmig über die Bereiche seitlich der Laschen vorsteht.A pot-shaped housing 1 has a flange-like edge 2 for supporting a bearing plate, not shown. Permanent magnets 3 , 4 of the electric motor are arranged in the housing 1 . Between the permanent magnets, the housing is deformed inwards over the entire length, so that indentations 10 , 11 have formed. In the area of each indentation 10 , 11 there is a tab 5 or 6 , which lies in the plane of the edge 2 , represents a widening of the edge 2 and has a through hole 7 or 8 . As a result of the indentations, the tabs 5 , 6 and also the bores can be moved further inward, so that the flange at this point, depending on the strength of the indentation, protrudes radially only slightly beyond the areas to the side of the tabs.
