RADIAL-AXIAL SLIDING BEARING

摘要

FIELD: machine building.SUBSTANCE: invention refers to machine building and can be used in different friction assemblies. A radial-axial sliding bearing includes a sleeve from antifriction material with an external cylindrical mounting surface and working surfaces. A working surface for taking a two-sided axial load is made in the form of several annular grooves with a triangular equilateral profile. The sleeve can be of split type and can have the possibility of mounting a counterbody on annular grooves. Annular grooves are arranged on inner surface of split-type rings mounting as to sliding fit into the sleeve. Outer surface of split-type rings is connected to the sleeve by means of elastic annular elements. Elastic annular elements are made in the form of springs. Split-type rings are made from antifriction material, for example fluoroplastic.EFFECT: increasing durability of a sliding bearing and its use at operation with dynamic loads and temperature drops.3 cl, 1 dwg
