Description

Die Erfindung betrifft eine Bürstenführung, die aus einer Bürstenführungsbuchse und einem diese umfassenden Preßstoffmantel besteht und die in einem Tragkörper, z. B. einem Lagerschild, eingesetzt wird.The invention relates to a brush guide which consists of a brush guide bush and a pressed material jacket comprising these and which is in a support body, z. B. a bearing plate is used.

Nach einem älteren Vorschlag erhalten Bürstenführungen .der vorerwähnten Art am Umfang des Preßstoffmantels Anschwellungen in Gestalt von Stegen, Wülsten :od. d:gl., :die nach Einschieben der Bürstenführung .in den Tragkörper die Bürstenführung im Tragkörper festhalten, ohne daß durch die Anschwellungen auf dem Preßstoffm.antel ein den Tragkörper dehnender Druck auftritt. Solche Bürstenführungen werden gemäß der Erfindung namentlich bei mehreckigen, insbesondere viereckigen Querschnitten der Bürstenführungsbuchse in der Weise weiter ausgestaltet, daß die Anschwellungen am Umfang des Preßstoffmantels in den Diagonalebenen der Bürstenführungsbuchse vorgesehen werden.According to an older proposal, brush guides are given the aforementioned Type of swellings on the circumference of the pressed material jacket in the form of webs, beads : od. d: gl.,: the brush guide after pushing the brush guide into the support body Hold tight in the support body without swelling on the Preßstoffm.antel a pressure which expands the support body occurs. Such brush guides are according to of the invention in particular in the case of polygonal, in particular square, cross-sections the brush guide bushing further designed in such a way that the swellings provided on the circumference of the pressed material jacket in the diagonal planes of the brush guide bushing will.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Bürstenführung i besteht aus der metallenen Bürstenführungsbuchse 2, die beispielsweise aus einem gezogenen Rohr hergestellt und in den Preßstoffrnantel 3 eingebettet ist. Mit diesem Preßstoffmantel 3 wird die Bürstenführung in den Tragkörper 4, beispielsweise: ein Auge, eingesetzt, wobei sich die Anschwellungen 5 in der gegebenenfalls geriffelten Innenwand des Auges 4 festsetzen. Wie man aus der Zeichnung ersieht, sind die Anschwellungen 5 so, angeordnet, daß sie auf den Verlängerungen der Diagonalebenen 6 und 7 der Bürstenführüngsbuchse 2 liegen.An exemplary embodiment of the invention is shown in the drawing. The brush guide i consists of the metal brush guide bushing 2, for example made of a drawn tube and embedded in the Preßstoffrnantel 3 is. With this pressed material jacket 3, the brush guide is in the support body 4, for example: one eye, inserted, the swellings 5 in the possibly corrugated Fix the inner wall of the eye 4. As can be seen from the drawing, the swellings are 5 so arranged that they are on the extensions of the diagonal planes 6 and 7 of the Brush guide bush 2 lie.

Es ist naturgemäß nicht nötig, daß der Preßstoffmantel zylindrischen Querschnitt hat; es ist auch möglich"daß die Preßstoffmäntel kantig ausgeführt sind. In diesem Fall empfiehlt es sich, darauf zu achten, daß die Kanten des Preßstoffmantels, ,die naturgemäß die Anschwellungen zu ersetzen haben, so liegen, daß die Verlängerungen .der Diagonalebenen .der metallenen Bürstenführungsbuchse ebenfalls durch sie gehen.It is of course not necessary for the molded material jacket to be cylindrical Cross-section has; it is also possible that the pressed material jackets are edged. In this case it is advisable to make sure that the edges of the pressed material jacket, , which naturally have to replace the swellings, lie so that the extensions .the diagonal planes .the metal brush guide bushing also go through them.
