A leveling plate for a dynamic pressure gas thrust bearing, a distance-adjustable top foil, and a thrust bearing

Abstract

The invention discloses a leveling plate, a distance-adjustable top foil, and a thrust bearing for a dynamic pressure gas thrust bearing; it belongs to the field of electric air compressors for new energy vehicles; its technical points: it is arranged between the wave foil and the top foil, The leveling plate includes: a second plate, a plurality of leveling bead groups, and holes are arranged inside the second plate; the leveling bead group corresponds to the foil of the corrugated foil, and the leveling bead The set is in contact with the top of the corrugated foil; the set of leveling bead is arranged circumferentially inside the second plate. The invention aims to provide a leveling plate, a distance-adjustable top foil and a thrust bearing for a dynamic pressure gas thrust bearing, so as to improve the working performance of the thrust bearing.

Description

technical field [0001] The 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 used in practice
