Abstract

The invention discloses a thrust ball bearing, belonging to the field of bearings. The thrust ball bearing disclosed by the invention comprises a shaft ring, a seat ring, a steel ball and a retainer, wherein the seat ring and the shaft ring are sheets; the steel ball is supported between the shaft ring and the seat ring by virtue of the retainer; annular grooves which correspond to the steel ball are respectively formed in the inner side end surfaces opposite to the seat ring and the shaft ring; the upper end surface of the retainer correspondingly faces the shaft ring; the lower end surface of the retainer correspondingly faces the seat ring; an upper annular cover which extends upwards along the axial direction is arranged on the upper end surface of the retainer; a lower annular cover which extends downwards along the axial direction is arranged on the lower end surface of the retainer; and pressing surfaces which are correspondingly pressed on the outer side end surfaces opposite to the shaft ring and the seat ring are respectively formed in the upper annular cover and the lower annular cover. The upper annular cover and the lower annular cover are connected and pressed, so that the shaft ring, the seat ring, the retainer and the steel ball form a connected combination. According to the thrust ball bearing disclosed by the invention, the noise is reduced, and the stability is improved.

Description

technical field [0001] The invention belongs to the field of bearings, and in particular relates to a thrust ball bearing. Background technique [0002] Components such as refrigeration compressors usually use thrust ball bearings to support the rotation of the shaft. The existing thrust ball bearings are composed of a seat ring, a shaft ring and a cage, and the steel balls installed between the seat ring and the shaft ring are supported by the cage. The ring, shaft ring and cage are all flat-plate type. Generally, there is no groove on the seat ring and shaft ring, and the seat ring, shaft ring and cage are separated in three pieces. When the speed is high, the noise generated is relatively large. The energy consumption is large, and the position of the steel ball is prone to misalignment when the axial movement occurs, resulting in a sudden increase in noise at a certain moment. Contents of the invention [0003] The purpose of the present invention is to overcome the...
