Description

Zur -Zentrierung .der Lagerstellen (Lagerbügel, Lagerschilden-) bei Elektromotoren hat man bisher das Gehäuse und die Lagerstellen mit Zentrierrändern versehen, die durch- Abdrehen hergestellt wurden. Dieses Abdrehen -verursacht einen verhältnismäßig großen Arbeitsaufwand. Um diesen zu vermeiden, werden gemäß der Erfindung an Stelle yon Zentrierrändern nur einzelne Zentrierpünkte vorgesehen, indem ,der Ständer Ausnehmungen erhält, in welche. entsprechende Vorsprünge der Lagerstellen eingreifen, oder an den Lagerstellen sind einzelne Ausnehmungen vorgesehen,,. an welche Vorsprünge des Gehäuses eingreifen. Die Erstellung dieser Ausnehmungen kann z. B. durch Bohren mittels einer Bohrlehre,7durch Ausstanzen " usw. erfolgen. Die Vorsprünge kann man durch Einsetzen von Paßistiften in mittels -einer Bohrlehre hergestellten Löcheiri vornehmen oder auch beispielsweise durch Pressen. Alle diese Arbeitsvorgänge beanspruchen weniger Zeit als das Abdrehen von zylindrischen Paßrändern. Besonders zweckmäßig -ist es, dien Ständer ohne Gehäuse auszuführen. Der Ständer erhält dann verstärkte Endbleche, in welchen .durch Stanzen Aussparungen vorgesehen sind, in die entsprechende Vorsprünge der Lageretellen eingreifen.For centering the bearing points (bearing bracket, end shields) So far, electric motors have the housing and the bearings with centering edges provided that were made by turning. This twisting causes one relatively large amount of work. To avoid this, according to the Invention, instead of centering rims, only individual centering points are provided, in that the stand receives recesses in which. corresponding projections of the Intervene bearing points, or individual recesses are provided at the bearing points. which protrusions of the housing engage. The creation of these recesses can e.g. B. by drilling by means of a drilling jig, 7 by punching ", etc. take place. The projections can be made by inserting dowel pins in a drilling jig made Löcheiri or, for example, by pressing. All these Operations take less time than turning off cylindrical mating edges. It is particularly useful to design the stand without a housing. The stand then receives reinforced end plates in which cutouts are provided by punching engage in the corresponding projections of the bearing parts.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, Wie aus den Fig. i und 2 ersichtlich, besitzt das aus einzelnen Blechen geschichtete Ständerblechpaket .i verstärkte Endbleche 2. Zum Zusammenhalten des Blechpaketes dienen Rohrniete 3 und 4. Die Endbleclie werden nach denn Zusammenbau planparallel abgeschliffen: Sie besitzen Ausnelimungen die beim Stanzen dieser Bleche hergestellt werden. I.n diese Ausneliinungen passen entsprecliende Vorsprünge 7 der Lagerbügel 6, die in den Fig.3 und 4 dargestellt sind. Die Lagerbügel sind aus Blech gezogen. Die Vorsprünge werden durch Pressen in einer Form hergestellt. Durch die Rohrniete n werden Bolzen gezogen, die zur Befestigung der Lagerbügel an dein Blechpaket dienen. 3lan erhält auf diese Weise ein Ständerblechpaket mit 1:agerliiigeln, das in einfacher Weise hergestellt werden kann.An embodiment of the invention is shown in the drawing, As can be seen from FIGS. I and 2, it has the layered sheet metal Stator laminated core .i reinforced end plates 2. To hold the laminated core together are used tubular rivets 3 and 4. The end plates are plane-parallel after assembly Abraded: They have cutouts that are produced when these sheets are punched will. Corresponding projections 7 of the bearing bracket fit into these openings 6, which are shown in FIGS. The bearing brackets are drawn from sheet metal. The protrusions are made by pressing in a mold. Through the tubular rivet n bolts are pulled that are used to attach the bearing bracket to your laminated core. In this way, 3lan receives a stator core with 1: brackets, which can be done in a simple Way can be made.

Die Anordnung nach der 7?rfindung ist nicht nur anwendbar bei Elektromotoren, sondern auch bei elektrischen Generatoren, bei Drehspulen und Drehspulrelais und ähnlichen Apparaten, -also überall da, wo ein _ drehbarer Anker sich in einem Ständ,erblechpaket bewegt.The arrangement according to the invention is not only applicable to electric motors, but also with electrical generators, with moving coils and moving coil relays and Similar devices, i.e. wherever a rotatable armature is in a stator core emotional.
