Embodiment Construction

[0034] exist Figures 1A-1B Axial-radial sliding bearings are generally marked with 10 in the middle. It comprises a first bearing ring 11 and a second bearing ring 12 , which are produced in a known manner, typically both from metal, for example from aluminium. One or both of the two bearing rings 11, 12 can be made of a suitable plastic. The second bearing ring 12 is embodied as an inner ring in the example shown and has a substantially U-shaped cross-section. The second bearing ring 12 thus forms a receptacle in which the radially inner region of the first bearing ring 11 is received over its entire surface. The second bearing ring 12 as from Figure 1A As can be seen most clearly, it consists of two parts that are flanged against each other by a screwed connection. In the example shown, the first bearing ring 11 is embodied as an outer ring and in one piece. Due to the corresponding play or gap between the two bearing rings 11 , 12 they can rotate about the bearing axi...

Abstract

The invention relates to an axial-radial plain bearing (10) with polymer sliding elements (20). Comprising a first bearing ring (11) and a second bearing ring (12) rotatable relative to each other about a bearing axis (A), the second bearing ring (12) forming a substantially U-shaped cross-section to at least partially receive the first Bearing ring (11). A sliding element (20) is made of a friction polymer and is arranged between the first bearing ring and the second bearing ring in order to decouple these bearing rings axially and radially. The sliding element (20) has a substantially L-shaped cross-section with an axial region (21) with an axial sliding surface and a radial region (22) with a radial sliding surface. According to the invention, the radial region ( 22 ) of the slide bearing ( 20 ) has at least one joint connection ( 23 ), which connects the two sections ( 24 ) of the radial region in a flexible and movable manner relative to each other. Thereby, the sliding element (20) can be adapted to a corresponding diameter (D) of the axial-radial sliding bearing (20). The invention also relates to a sliding element (20) having at least one such hinge connection (23) in a radial region (22) of the sliding element (20).

Description

technical field [0001] The invention relates generally to a combined axial / radial plain bearing with polymer sliding elements and to a polymer sliding element developed especially for such a plain bearing. Background technique [0002] A combined axial / radial plain bearing of composite construction is known from US Pat. No. 5,509,738. In this case, a sliding element made of a polymer, in particular polyimide, is attached to a bearing half made of metal. To form the disk-shaped axial sliding surface, a plurality of segments made of polyimide are applied by gluing. In order to provide a cylindrical radial sliding surface, a plurality of curved strips made of polyimide are glued onto the inner circumference of the bearing shell. A disadvantage is, for example, that the segments and the curved strips have to be adapted to the dimensions of the corresponding bearing shell. Furthermore, such a composite plain bearing according to US Pat. No. 5,509,738 is expensive to manufactur...
