Problems solved by technology

[0009] Disadvantages of all the above methods are either that the bearings are not produced with sufficient precision and therefore have unsatisfactory characteristics, or that the manufacturing methods mostly require several consecutive process steps and machining of different materials, which makes the manufacturing process lengthy and expensive and limits the Bearing Durability

Embodiment Construction

[0043] FIG. 1 shows a plastic filament 10 according to the invention as reinforcement for the outer ring sliding layer in an enlarged sectional view. The plastic filament consists of polyester filaments 12 oriented along the filaments and comprises as a second component PTFE particles 14 , which are woven into the polyester filaments 12 in a random arrangement. During the manufacturing process, there are numerous possibilities for changing the properties of the filament. For example, the number of polyester filaments 12 per filament 10 can vary depending on the application. In this connection, however, a sufficient form connection to the bonded PTFE particles 14 should be taken into account.

[0044] The weight ratio between polyester filaments 12 and PTFE particles 14 can likewise vary. However, it is particularly preferred that it proves beneficial, taking into account the adhesion, friction and sliding properties, if the percentage by weight of PTFE particles 14 in the pl...

Abstract

The invention relates to an outer ring of joint bearing with a built-in sliding layer and an exposed bearing layer, wherein the sliding layer and the bearing layer are composed of winding fiber composite material. The outer ring has only one dividing slot. The invention also relates to a joint axle with the said outer ring and manufacturing method thereof. A sliding and bearing layer formed by synthetic resin impregnation fiber are winded in turn along a winding mandrel and the winding body generated by the above step forms outer ring after hardening. The said sliding and bearing layer are winded along a cylindric winding mandrel, the outer ring has only one dividing slot and the shape of the material of sliding layer at the medial side is abraded to obtain an inner ring in which the partly spherical outline is used to house complementation.

Description

technical field [0001] The invention relates to an outer ring of a spherical plain bearing or such a spherical plain bearing, wherein the outer ring has an inner sliding layer and an outer carrier layer and wherein the sliding layer and the carrier layer consist of wound fiber composite material. The invention furthermore relates to a method for producing such an outer ring, in which a sliding layer and a carrier layer of synthetic resin-impregnated fibers are successively wound on a winding mandrel and after hardening are formed by such The resulting jellyroll forms the outer coil. Background technique [0002] Such a method is known, for example, from DE 42 20 327 . In the method disclosed there for producing spherical plain bearings, a winding core is used which consists of alternately arranged molding rings for forming the pot-shaped inner profile of the outer ring and boundary rings for forming the end flanks. Synthetic resin-impregnated PTFE and / or high-strength fibe...
