Description

Pendelgleitlager für Elektrokleinmotoren Die Erfindung betrifft ein Pendelgleitlager für Elektrokleinmotoren, bei dem eine aus Sintermetall bestehende Kalotte durch einen aus Blech bestehenden, topfförmigen Lagerkörper federnd gehalten wird.Self-aligning plain bearings for small electric motors The invention relates to a Self-aligning plain bearings for small electric motors, one of which is made of sintered metal The spherical cap is resiliently held by a cup-shaped bearing body made of sheet metal will.

Die bekanten Ausführungsformen dieser Art lösen nicht die Aufgabe, ein schnelles Einsetzen und Herausnehmen des gesamten Lagers- zu ermöglichen; sie lösen auch nicht die Aufgabe, einen sicheren Sitz des Lagers in der zugehörigen Lagerschildbohrung ohne zusätzliche Befestigungsmittel zu gewährleisten; ferner ist der genau richtige Sitz des Gleitlagers im Lagerschild nicht unbedingt gewährleistet.The known embodiments of this type do not solve the problem to enable quick insertion and removal of the entire bearing; she also do not solve the problem of a secure fit of the bearing in the associated To ensure end shield drilling without additional fasteners; further the correct seating of the plain bearing in the end shield is not guaranteed.

Diese Aufgabe erfüllt die Erfindung dadurch, daß der topfförmige Lagerkörper leicht kegelig gestaltet und mit einem ringflanschartigen Anschlag versehen ist, in dem die federnde Abschlußscheibe eingebördelt ist.This object is achieved by the invention in that the cup-shaped bearing body is slightly conical in shape and provided with an annular flange-like stop, in which the resilient cover plate is crimped.

Ferner schlägt die Erfindung vor, das Lagergehäuse bzw. den Lagerkörper als radial federnden Körper auszubilden.The invention also proposes the bearing housing or the bearing body to be designed as a radially resilient body.

Erfindungsgemäß kann der Abschlußscheibe eine Vorspannung zwecks Erzielung einer Flächenpressung zwischen Kalotte und den Halterungsflächen gegeben werden.According to the invention, the cover plate can be pretensioned in order to achieve this a surface pressure between the dome and the mounting surfaces are given.

Erfindungsgemäß kann ferner um die Kalotte herum ein abgeschlossener hohler Ringraum als Schmierraum vorgesehen sein.According to the invention, there can also be a closed one around the dome hollow annular space can be provided as a lubricating space.

Für die Unteransprüche wird Schutz nur im Zusammenhang mit dem Hauptpatent begehrt.For the subclaims, protection is only given in connection with the main patent desired.

Die Erfindung ist an Hand eines Ausführungsbeispiels in der Zeichnung dargestellt, und zwar zeigt Fig. 1 ein Pendelgleitlager gemäß der Erfindung im Axialschnitt, Fig. 2 einen Axialschnitt mit Vergleich des erfindungsgemäßen Lagers gegenüber einem üblichen Kugellager.The invention is based on an exemplary embodiment in the drawing shown, namely Fig. 1 shows a self-aligning plain bearing according to the invention in axial section, 2 shows an axial section with a comparison of the bearing according to the invention with respect to one usual ball bearings.

Der Lagerkörper 1 ist topfartig ausgebildet und hält die Abschlußscheibe 2 vermittels einer Umbördelung 6. Der Lagerkörper 1 besitzt eine Kalottenfläche 4, die Abschlußscheibe 2 besitzt ebenfalls eine Kalottenfläche 5. Diese Kalottenflächen 4, 5 dienen als Lagerflächen für die im Lagerkörper 1 gefaßte Sintermetallkalotte 3, welche die zur Aufnahme der Motorwelle dienende Lagerbohrung 7 besitzt.The bearing body 1 is cup-shaped and holds the cover plate 2 by means of a flange 6. The bearing body 1 has a spherical cap surface 4, the cover plate 2 also has a cap surface 5. These cap surfaces 4, 5 serve as bearing surfaces for the sintered metal dome held in the bearing body 1 3, which has the bearing bore 7 serving to accommodate the motor shaft.

Wichtig ist, daß der Umfangsbereich 8 des Lagerkörpers 1 leicht kegelig ausgestaltet ist. Wenn nämlich das Pendelgleitlager gemäß Fig.1 von rechts nach links in die Bohrung des Lagerschildes 9 eingedrückt wird, dann federt der Lagerkörper 1 in radialer Richtung etwas ein, und es ergibt sich ein guter Festsitz; hierbei wirkt die ringflanschartige Umbördelung 6 als Anschlag zwecks genauer axialer Fixierung.It is important that the peripheral area 8 of the bearing body 1 is slightly conical is designed. If namely the self-aligning plain bearing according to Figure 1 from right to is pressed left into the bore of the end shield 9, then the bearing body springs 1 a little in the radial direction, and there is a good tight fit; here the ring flange-like bead 6 acts as a stop for the purpose of more precise axial fixation.

Um die Kalotte 3 herum befindet sich der bei eingesetztem Zustand des Lagers völlig abgeschlossene Hohlraum 10 als Schmierraum zur Aufnahme von Reservefett od. dgl.Around the spherical cap 3 is the one when it is in the inserted state of the bearing completely closed cavity 10 as a lubricating space for receiving reserve grease or the like

Es ist noch zu bemerken, daß es vorteilhaft ist, der Abschlußscheibe 2 eine Vorspannung von der Art zu geben, daß die Flächen 4, 5 stets mit genügendem Anpressungsdruck an der balligen Umfläche der Kalotte 3 anliegen, und zwar gleichgültig, welche momentane Winkellage die Kalotte besitzt.It should also be noted that it is advantageous to use the lens 2 to give a bias of the kind that the surfaces 4, 5 always with sufficient Contact pressure on the spherical surface of the spherical cap 3, regardless of whether which current angular position the dome has.

Fig. 2 zeigt, daß ein übliches Kugellager K durch ein mit entsprechend gleichen Abmessungen versehenes erfindungsgemäßes Pendelgleitlager G in einfachster Weise ersetzt werden kann. Die Möglichkeit der Umrüstung vorhandener Kleinmotoren ist also ohne weiteres gegeben.Fig. 2 shows that a conventional ball bearing K by a correspondingly Self-aligning plain bearing G according to the invention provided with the same dimensions in the simplest form Way can be replaced. The possibility of retrofitting existing small motors is therefore given without further ado.

Das Lager gemäß der Erfindung besteht nur aus sehr wenigen einfach zu fertigenden Teilen, ist also im Vergleich zu anderen, ähnlichen Zwecken dienenden Lagern besonders wirtschaftlich. Es kann jederzeit ohne Lösen besonderer Festhalteeinrichtungen entnommen oder eingesetzt werden. Irgendwelche Abänderungen von Kleinmotoren, die an Stelle von Kugellagern oder anderen Lagern mit dem erfindungsgemäßen Lager ausgerüstet werden sollen, sind nicht notwendig.The camp according to the invention consists of very few simple parts to be manufactured, is therefore in comparison to other, similar purposes Storage particularly economical. It can be used at any time without releasing special retaining devices removed or inserted. Any modifications of small engines that equipped with the bearing according to the invention instead of ball bearings or other bearings are not necessary.
