Abstract

The invention discloses an air compressor thrust bearing arrangement structure, and relates to the technical field of thrust bearings, the air compressor thrust bearing arrangement structure cancels a thrust plate, and comprises a motor, a rotating shaft, a thrust bearing and an impeller; the rotating shaft is arranged at the output end of the motor, the impellers are arranged at the two ends of the rotating shaft, and the thrust bearings are arranged on the back faces of the impellers. Thrust plates are omitted, the thrust bearings are arranged at the two ends, thrust is formed by the thrust bearings and the back faces of the impellers at the two ends, the axial occupied space is reduced, the structure is simplified, and meanwhile the stability of the rotor assembly is improved.

Description

technical field [0001] The invention relates to the field of thrust bearings, in particular to an arrangement structure of thrust bearings of an air compressor. Background technique [0002] The proton exchange membrane fuel cell system is an efficient and clean new energy power system. The air compressor compresses the air into high-pressure air, and then sends it to the cathode of the fuel cell. The oxygen in the air reacts electrochemically with the hydrogen in the anode to generate The products produced are electricity and water, and part of the heat is discharged into the atmosphere along with the excess air. There are no other products that pollute the environment, so the fuel cell power system is very clean and environmentally friendly, and there are many production methods for hydrogen. Clean and renewable energy, countries around the world are vigorously promoting the development and promotion of hydrogen fuel cell power systems. The air compressor dedicated to the...
