Abstract

The bracket (1) is a steel pressing with a raised central area (2) to provide rigidity; a hole (3) for the pivot bolt and a guiding slot (4). A tubular projection (7) is pressed out of the bracket and its outer surface forms a support for the inner race of a ball bearing. The outer race of the bearing serves as the tension roller. A projection (6) is formed by cutting three sides of the slot (5) and bending the tag upwards, and serves as an anchorage for the belt tension spring. The bracket is particularly useful for tensioning the toothed belts of engine cam shaft drives.

Description

Lagerplatte zur schwenkbaren Lagerung einer auf ihr befestigten Spannrolle (Zusatz zu Patent .. (Patentanmeldui P 23 43 748.1) Das Hauptpatent betrifft eine Lagerplatte aus Blech zur schwenkbaren Lagerung einer auf ihr befestigten Sparlnrolle, wobei die Lagerplatte mit einer einstückig angeformter hohlzylindrischen Ausstülpung versehen ist, die die Spannrolle trägt.Bearing plate for the swiveling mounting of a tensioning pulley attached to it (Addition to patent .. (Patentanmeldui P 23 43 748.1) The main patent concerns a Bearing plate made of sheet metal for the swiveling mounting of an economy roll attached to it, wherein the bearing plate with an integrally formed hollow cylindrical protuberance is provided that carries the tensioner pulley.

Durch diese Ausbildung einer Lagerplatte wird unter Vermeidung einer Vielzahl von Einzelteilen eine besonders ein fache und damit kostengünstige Herstellung erzielt.This formation of a bearing plate is avoided while avoiding a Large number of items a particularly simple and thus inexpensive production achieved.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine derartige Lagerplatte dadurch weiter zu vereinfachen, daß erneut ein weiteres zusätzliches Bauteil entfällt.The present invention is based on the object of such To further simplify the bearing plate that again another additional Component is omitted.

Gemäß der Erfindung liegt die Lösung dieser Aufgabe darin, in die hohlzylindrische Ausstülpung der Lagerplatte selbst eine umlaufende Nut einzuformen, in der ein Kranz von Kugeln abrollt, der den die eigentliche Rolle bildenden Außenring trägt. Durch diese Maßnahme wird erreicht, daß der bisher benötigte Innenlaufring für das die Rolle tragende Wälzlager entfallen kann.According to the invention, the solution to this problem is in the hollow cylindrical protuberance of the bearing plate itself to form a circumferential groove, in which a ring of balls rolls off the outer ring that forms the actual role wearing. This measure ensures that the previously required inner race for which the roller bearing bearing the role can be omitted.

In der Zeichnung ist ein Ausführungsbeispiel der beschriebenen Erfindung im Längsschnitt dargestellt.In the drawing is an embodiment of the invention described shown in longitudinal section.

Die Lagerplatte 1 ist im wesentlicher eben ausgebildet, weist jedoch aus Gründen der Versteifung ifl ihrem mittleren Bereich eine schalenartige Erhöhung 2 auf. Gemäß dem Hauptpatent ist die Lagerplatte 1 mit einer einstückig angeformten hohlzylindrischen Ausstülpung 7 versehen. Im Bereich dieser hohlzylindrischen Aasstülpung 7 ist eine umlaufende Nut 18 eingeformt, in aer die Kugeln 13 abrollen, die den Außenring 12 tragen, der die eigentliche Rolle bildet.The bearing plate 1 is essentially flat, but has for reasons of stiffening, a bowl-like elevation in the middle area 2 on. According to the main patent, the bearing plate 1 is integrally formed with a hollow cylindrical protuberance 7 provided. In the area of this hollow-cylindrical protrusion 7, a circumferential groove 18 is formed, in which the balls 13 roll, which the Wear outer ring 12, which forms the actual role.

Die Einformung der umlaufenden Nut 18 kann ausschließlich auf spanlosem Wege, z.B. durch Einrollen erfolgen. Wenn es für erforderlich gehalten wird, kann sich daran jedoch auch eine spanabhebende Feinbearbeitung. z.B. Schleifen anschliessen.The molding of the circumferential groove 18 can only be done without cutting Ways, e.g. by rolling up. If deemed necessary, can However, this also includes machining fine machining. e.g. connect loops.
