AXIAL-RADIAL SLIDE BEARING HAVING POLYMER SLIDE ELEMENTS AND CORRESPONDING SLIDE ELEMENT

摘要

This invention relates to an axial-radial sliding bearing (10) with polymer sliding elements (20). The sliding bearing comprises a first bearing race (11) and a second bearing race (12), which are rotatable oppositely to each other about a bearing shaft (A), wherein the second bearing race defines a substantially U-shaped cross section for receiving the first bearing race at least in certain regions. The sliding elements (20) are made from tribopolymer and are arranged between the first and the second bearing races for uncoupling the bearing races axially and radially. The sliding elements each have a substantially L-shaped cross section comprising an axial region (21) having axial sliding surfaces and a radial region (22) having radial sliding surfaces. According to the invention, the radial region (22) of the sliding elements (20) includes at least one hinge connection (23), which connects two segments (24) of the radial region in a flexible manner and so as to be movable oppositely to each other. Thus the sliding elements (20) can be adapted to the respective diameter (D) of the axial-radial sliding bearing (10). The invention also relates to a sliding element (20) including at least one such hinge connection (23) in the radial region (22) of the sliding element (20).

1. Axial-radial sliding bearing with polymer sliding elements, comprising:
a first bearing race and a second bearing race which are rotatable oppositely to each other about a bearing shaft, wherein the second bearing race defines a substantially U-shaped cross section for receiving the first bearing race at least in certain regions; sliding elements made from a polymer, in particular from a tribopolymer, which are arranged between the first and the second bearing races for uncoupling the bearing races axially and radially, wherein the sliding elements each have a substantially L-shaped cross section comprising an axial region having axial sliding surfaces and a radial region having radial sliding surfaces; characterized in that the radial region of the sliding elements includes at least one hinge connection, which connects two segments of the radial region in a flexible manner and so as to be movable oppositely to each other so that the sliding elements are adapted to the respective diameter of the axial-radial sliding bearing.
