In a specific embodiment, rotor assembly provided by the present invention, including bent axle 11 and set
The rotor 12 being loaded on the eccentric part 111 of bent axle 11, eccentric part 111 outer peripheral face of bent axle 11
On there is fitting recess 112, be provided with inner ring surface with rotor 12 in fitting recess 112 and roll and coordinate
Rolling member 13.
During assembling uses, by the rolling member 13 being arranged in fitting recess 112 and rotor
In rolling cooperation replacement prior art between 12 inner ring surfaces between crankshaft eccentric portion 111 and rotor 12
Be slidably matched, make in equipment running process the slip between crankshaft eccentric portion 111 and rotor 12 rub
Wiping becomes rolling friction, thus greatly reduces the compressor power consumption caused because of sliding friction,
Improve whole work efficiency and the operational reliability thereof of compressor.
Further, fitting recess 112 is the axially arranged elongated slot along bent axle 11, rolling member
13 is the roller bearing suitable with elongated slot.The rolling matching structure of this kind of roller bearing and elongated slot adaptation can
