Abstract

The invention discloses an air compressor, a motor and an aerodynamic thrust bearing. The aerodynamic thrust bearing comprises a bearing seat, a bottom foil, a split type corrugated foil and a split type top foil, wherein rivets are arranged on the bottom foil, rivet holes matched with the rivets are formed in the split type corrugated foil and the split type top foil, and the split type corrugated foil and the split type top foil sequentially penetrate through the rivets of the bottom foil to achieve riveting connection of the split type corrugated foil, the split type top foil and the bottomfoil. The above connection mode relative to a coupling connection mode has the advantage that the machining difficulty of the rivets and the rivet holes is relatively low, so that the machining difficulty of the aerodynamic thrust bearing is reduced to a certain degree.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an air compressor, a motor and a gas dynamic pressure thrust bearing. Background technique [0002] A gas bearing is a sliding bearing that uses gas as a lubricant. [0003] Foil type gas dynamic pressure thrust bearing is a kind of gas bearing, including top foil, corrugated foil, bottom foil and bearing seat. The bearing seat is a cylindrical annular bearing seat, and the top foil and corrugated foil are generally split Type structure, the bottom foil is a whole piece structure, and there are mounting holes on the bottom foil to cooperate with the rotor. Specifically, the outer periphery of the bottom foil is connected to the inner wall of the bearing seat, and the bottom foil, the corrugated foil and the top foil are stacked sequentially from bottom to top. The corrugated foil is an elastic foil. During the operation of the bearing, the corrugated foil can be slightl...
