Description

Verfahren zur Herstellung von nahtlosen Lagerbuchsen aus mit Kunstharz getränktem Gewebe Nach dem Patent 88z 579 werden nahtlose,B'uchsen aus mit Kunstharz getränktem Gewebe dadurch hergestellt, daß ein vorgewickelter Rohrabschnitt unter Wärme durch einen sich erweiternden und mit einem die Teilungsfugen überdeckenden federnden Stahlmantel versehenen inneren Dorn gegen die ungeteilte Außenform gepreßt wird. Bei dieser Art der Buchsenherstellung werden. die in, die Preßform einzulegenden Rohrwickel in bekannter Weise hergestellt, und zwar wird auf einen eisernen Dorn die mit Kunstharz getränkte Gewebebahn unter Druck aufgewickelt. Dann werden die Rohre in einzelne Rohrabschnitte zerteilt. Gemäß der Erfindung werden zur Buchsenfertigung nicht in üblicher Weise vorgewickelte Rohrabschnitte in die Preßform eingelegt, sondern das mit Kunstharz getränkte und- in entsprechend breite Streifen geschnittene Gewebe auf den federndem Metallmantel aufgewickelt. Durch diese Art der Herstellung lassen sich im Gefüge gleichmäßigere Buchsen erzielen. Ein weiterer Vorteil liegt aber darin, daß nunmehr in besonders einfacher Weise Buchsen mit Schmiernuten hergestellt werden können. Dazu werden auf den federnden Metallmantel mehrere entsprechende Vorsprünge angebracht, die z. B. in Richtung der Lagerachse verlaufen und über den Umfang des federnden Metallmantels verteilt sind. Das Gewebe wird beim Aufwickeln mit einer elastischen Walze festgedrückt. Zum Verpressen wird der zum Aufwickeln dienende Metallmantel durch einen anderen glatten, d. h. also ohne Vorsprünge gemäß Patent 881 579 ersetzt und die vorgewickelten Nuten im Rohrwinkel durch Nutkeile ausgefüllt. Nach dem Verpre.ssen lassen sich diese Nutkeile leicht entfernen. Die Schmiernuten können in die Lagerbuchse beidseitig oder einseitig offen. oder auch an beiden Seiten geschlossen eingepreßt werden.Process for the production of seamless bearing bushings made with synthetic resin soaked fabric According to the patent 88z 579 seamless bushings made of synthetic resin Soaked fabric produced by a pre-wound tube section under Warmth through a widening and with a covering the dividing joints resilient steel jacket provided inner mandrel pressed against the undivided outer form will. With this type of socket production. those to be inserted into the mold Pipe winding made in a known manner, namely on an iron mandrel the synthetic resin-soaked fabric web is wound up under pressure. Then the Pipes divided into individual pipe sections. According to the invention for socket production Pipe sections that are not pre-wound in the usual way are placed in the mold, but the one soaked with synthetic resin and cut into correspondingly wide strips Tissue wound onto the resilient metal jacket. By this type of manufacture more uniform bushings can be achieved in the structure. Another benefit lies but in the fact that now sockets with lubricating grooves are made in a particularly simple manner can be. For this purpose, several corresponding ones are placed on the resilient metal jacket Projections attached, the z. B. extend in the direction of the bearing axis and over the Perimeter of the resilient metal jacket are distributed. The fabric is being wound up pressed with an elastic roller. For pressing, that is used for winding serving metal jacket by another smooth, d. H. so without projections according to Patent 881 579 replaced and the pre-wound grooves in the pipe angle with groove wedges filled out. After grouting, these slot wedges can be easily removed. the Lubrication grooves can be open on both sides or on one side in the bearing bush. or be pressed in closed on both sides.
