Title:
ROTOR ASSEMBLY, COMPRESSOR, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2022/179130
Kind Code:
A1
Abstract:
Provided is a rotor assembly (100), comprising a first rotor (12), a second rotor (13), a third rotor (22) and a fourth rotor (23); the first rotor (12) and the second rotor (13) are coaxially arranged, and the rotation directions of threads of the first rotor (12) and the second rotor (13) are opposite; the first rotor (12) comprises a first toothed surface (121), the first toothed surface (121) meshes with the third rotor (22) to drive the third rotor (22) to rotate, the second rotor (13) comprises a second toothed surface (131), the second toothed surface (131) meshes with the fourth rotor (23) to drive the fourth rotor (23) to rotate, and the surface area of the first toothed surface (121) is different from the surface area of the second toothed surface (131), so that the first rotor (12) and the second rotor (13) together form an axial force in a preset direction. In the rotor assembly, the movement of a first rotating shaft along its own axial direction can be restricted merely by providing a thrust bearing at one end of the first rotating shaft, rather than requiring to provide thrust bearings respectively at two ends of the first rotating shaft, thereby improving the stability of the rotor assembly during operation, thus improving the stability of a compressor during operation, further reducing the number of thrust bearings.
