Bearing assembly

Abstract

The invention discloses a bearing assembly, and belongs to the technical field of bearing structures. The bearing assembly comprises an upper ring, a lower ring and cages, wherein the cages are located between an outer ring and an inner ring, and the upper ring and the lower ring correspond to each other in size and are arranged in a vertical coaxial mode. The bearing assembly is characterized in that an annular upper slide way is arranged on the lower end surface of the upper ring in the circumferential direction of the upper ring; an annular lower slide way is arranged on the upper end surface of the lower ring in the circumferential direction of the lower ring; a sliding body is arranged between the upper slide way and the lower slide way and comprises a plurality of sliding blocks which are of arc-shaped structures; upper curved surface parts which are correspondingly attached to the upper slide way surface and lower curved surface parts which are correspondingly attached to the lower slide way surface are arranged on the sliding blocks; and the cages are provided with placement positions for sleeving of the corresponding sliding blocks, and a lubricating chamber is arranged between every two adjacent sliding blocks. According to the bearing assembly, the sliding body capable of sliding is arranged and replaces a rolling body in the prior art, so that the bearing capacity of a bearing adopting the sliding body is large, and the bearing is suitable for slow running and capable of meeting the working condition with large bearing capacity change.

Description

technical field [0001] The invention relates to the technical field of bearing structures, in particular to a bearing assembly. Background technique [0002] Thrust bearing is an essential component in the engineering field, which is mainly composed of upper ring, lower ring, cage and rollers. With the rapid development of the country, the application of thrust bearings is becoming more and more extensive. The existing thrust bearings basically have the problems of high processing cost, complex structure and small axial bearing capacity. [0003] Thrust bearings are special bearings used to bear axial force, that is, bearings that bear force in a direction parallel to the shaft. Thrust bearings can only bear axial loads, and one-way thrust bearings can only bear axial loads in one direction. Two-way thrust ball bearings can bear axial loads in two directions; thrust bearings cannot limit the radial displacement of the shaft, and the limit speed is very low, one-way thrust ...
