Abstract
The utility model discloses a rolling rotor compressor, which comprises an upper flange, a lower flange, and a crankshaft eccentric part; wherein the upper flange and the lower flange go through a shaft neck of the crankshaft and are respectively positioned on the both sides of the crankshaft eccentric part; both end faces of the crankshaft eccentric part are respectively opposite to the inner end faces of the upper flange and the lower flange. The both end faces of the crankshaft eccentric part are provided with mounting holes; the mounting holes are internally provided with roll balls, thus leading to rolling friction fit between the both end faces of the crankshaft eccentric part and the upper flange and the lower flange. The rolling rotor compressor effectively reduces the friction among the crankshaft eccentric part and the upper flange and the lower flange, improves the performance of the compressor and prolongs the service life of the compressor.
