Split air foil bearing easy to disassemble and air compressor with same

Abstract

The invention discloses a split air foil bearing easy to disassemble and an air compressor with the same. The split air foil bearing mainly comprises a radial bearing and a thrust bearing. The radial bearing comprises a bearing sleeve, radial bump foil and radial top foil, wherein the bearing sleeve, the radial bump foil and the radial top foil are coaxially arranged in sequence from outside to inside. The thrust bearing comprises a thrust disc, thrust bump foil and thrust top foil, wherein the thrust disc, the thrust bump foil and the thrust top foil are arranged in sequence from left to right. The air compressor mainly comprises a turbine, a nut, a rotor sleeve, the radial bearing, the thrust bearing, a turbine end bearing body, a motor base, an impeller end bearing body and a rotor shaft. According to the air compressor, by adopting the split air foil bearing easy to disassemble for supporting, the problem that frequent disassembly of a traditional air compressor influences dynamic balance of a rotor is well solved, the maintenance cycle can be shortened, and the maintenance cost can be lowered; by adopting the air dynamic pressure bearing for supporting, compared with the traditional air compressor, no hydraulic system is needed, the system is simpler, the cost is lower, and higher stability is achieved in high-speed operation.

Description

technical field [0001] The invention relates to the installation of an air bearing in an air compressor, in particular to an easily detachable split air foil bearing and an air compressor with the bearing. Background technique [0002] Gas bearings have the advantages of high speed, high precision, high temperature resistance, small friction loss, and long life. After rapid development in recent decades, gas bearings have been widely used in high-speed bearings, high-precision bearings and other fields. At present, air compressors mainly use floating bearings. Due to the need for lubricating oil, this kind of bearings limits the working speed and temperature of the air compressor, increases the size and complexity of the system, and also has serious hidden dangers of oil leakage. The air foil bearing is a self-supporting flexible hydrodynamic bearing, which uses the surrounding air (or other gases) as the working medium and lubricant. The use of air foil bearings to replace...

AI Technical Summary

Problems solved by technology

The supporting bearings in traditional air compressors are integral, so in the maintenance process of traditional air compressors, generally only need to disassemble the machine to replace new bearings, but it is inevitable to disassemble the turbine and rotor shaft in this process, which will affect the rotor The dynamic balance of the rotor, the dynamic balance of the rotor is a key factor for the normal and stable operation of the air compressor
