Description

Bei elektrischen Maschinen für geräuscharmen Lauf )jerden Gleitlager benötigt. Um zu vermeiden, daß bei dem Aufbau der Maschine eine sehr große Arbeitsgenauigkeit erforderlich ist, ist es auch bereits bekannt, sich selbständig einstellende Gleitlager, sogenanrite Pendelgleitlager, anzuwenden.In electrical machines for low-noise operation) every slide bearing needed. In order to avoid a very high level of working accuracy when building the machine is required, it is already known to use self-adjusting plain bearings, so-called self-aligning plain bearings.

Gegenstand der Erfindung ist ein solches Pendelgleitlager, das sich durch seinen einfachen Aufbau auszeichnet. Gemäß der Erfindung sitzt die mit einer Kugeloberfläche versehene Gleitlagerbuchse in einem Spritzgußteil und wird durch eine in dem Spritzgußteil eingerollte Scheibe gehalten.The invention is such a self-aligning plain bearing that characterized by its simple structure. According to the invention sits with a Ball-surface bearing bushing in an injection-molded part and is made by held a rolled in the injection molded disc.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Fig. i zeigt das Spritzgußteil vor dem Zusammenbau, Fig. 2 das zusammengebaute Lager und die Fig. 3 und 4 die Scheibe.Fig. I shows the injection molded part before assembly, Fig. 2 the assembled Bearings and Figs. 3 and 4 the disc.

Mit i ist das Spritzgußteil bezeichnet, in welches die kugelige Lagerbuchse 3 eingesetzt wird. Die Haltescheibe ist mit 2 bezeichnet. Das Lager wird in der Weise zusammengesetzt, daß in das Spritzgußteil i die Lagerbuchse 3 eingesetzt wird. Dann wird die Schmierscheibe4 eingefügt und hierauf die Haltescheibe 2 angebracht, die durch Umrollen des Vorsprungs 5 des Spritzgußteils i in dieses eingerollt wird. Dadurch wird in einfacher Weise die Befestigung der Lagerbuchse finit der kugeligen Oberfläche erreicht. Das Spritzgußteil ist an seinem äußeren Umfang zylindrisch, so daß es mit jedem Kugellager austauschbar ist. DieLagerschale 3 wird man aus einem Metall, z. B. aus Sintermetall, pressen. Der Vorteil der Anordnung nach der Erfindung besteht darin, daß trotz kugeliger Einsteilbarkeit des Lagers keine kugelige Bearbeitung notwendig ist.With i the injection molded part is referred to, in which the spherical bearing bush 3 is used. The retaining disk is designated by 2. The warehouse is in the Assembled way that the bearing bush 3 is used in the injection molded part i. Then the lubricating disk 4 is inserted and the retaining disk 2 is attached to it, which is rolled into this by rolling around the projection 5 of the injection molded part i. This makes the fastening of the bearing bush finite to the spherical in a simple manner Surface reached. The injection molded part is cylindrical on its outer circumference, so that it is interchangeable with every ball bearing. The bearing shell 3 is made from a Metal, e.g. B. from sintered metal, press. The advantage of the arrangement according to the invention is that despite spherical adjustability of the bearing no spherical machining necessary is.
