Title:
ROTOR ASSEMBLY, COMPRESSOR AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2022/179133
Kind Code:
A1
Abstract:
The present disclosure provides a rotor assembly (100), comprising: a first shaft (111), a second shaft (121), a first rotor portion (112) and a second rotor portion (122); the first rotor portion (112) is arranged on the first shaft (111), the second rotor portion (122) is arranged on the second shaft (121), the second rotor portion (122) and the first rotor portion (112) are engaged with each other, and the first rotor portion (112) is configured to rotate along with the first shaft (111), so as to drive the second rotor portion (122) to rotate around the second shaft (121). In the present disclosure, the second rotor portion is connected to the second shaft in a rolling manner, so that rolling friction is formed between the second rotor portion and the second shaft during operation, thereby reducing the amount of lubricating oil required, and increasing the efficiency of separation of lubricating oil. In addition, the rotor assembly does not need external stable oil supply during startup, and thus an oil pump or a complex oil sac structure does not need to be additionally configured for a compressor, so that the compressor has a simpler and more compact structure.
