Leveling plate for dynamic pressure gas thrust bearing, distance adjusting top foil and thrust bearing

Abstract

The invention discloses a leveling plate for a dynamic pressure gas thrust bearing, a distance adjusting top foil and a thrust bearing, belonging to the field of new energy automobile electric air compressors. The technical points are as follows: the leveling plate for the dynamic pressure gas thrust bearing is arranged between a bump foil and the top foil; the leveling plate comprises a second plate and a plurality of leveling function pressing strip groups; a hole is arranged in the second plate; the leveling function pressing strip groups correspond to foil sheets of the bump foil and is incontact with the top of the bump foil; and the leveling function pressing strip groups are arranged in the second plate along the circumferential direction. The invention aims to provide the levelingplate for the dynamic pressure gas thrust bearing, the distance adjusting top foil and the thrust bearing, so as to improve the working performance of the thrust bearing.

Description

technical field [0001] The present invention relates to the field of electric air compressors for new energy vehicles, and more specifically, relates to a leveling plate for a dynamic pressure gas thrust bearing, a distance-adjustable top foil, and a thrust bearing. Background technique [0002] F16C17 / 04 is a sliding contact bearing used only for axial loads; F16C17 / 08 is used to support the end faces of shafts or other components, such as thrust bearings. [0003] Compared with traditional rolling bearings or oil-lubricated sliding bearings, gas dynamic pressure thrust bearings have many advantages such as small mass, low wear resistance, long maintenance cycle, low operating cost, high operating speed, and wide operating temperature range. The core component of machinery; it is the core component of electric air compressors for new energy vehicles. Therefore, it has been the focus of research and development.

Problems solved by technology

[0015] However, if image 3 As shown, when the inventor team tried integral molding (that is, the second method), they found that there was a new problem in this method: the warping problem of the corrugated foil, that is, there was a serious warping problem at the end of the corrugated foil, so that As a result, the shape of the corrugated foil cannot meet the design requirements

This solution does partially improve the warpage, but it cannot really eliminate the warpage problem

[0019] However, if the warpage problem cannot be truly eliminated, the design similar to CN106763151A cannot be applied to actual
