Abstract

The invention discloses a rotary compressor, which comprises a casing, a cylinder assembly, a crankshaft, a driving motor, a piston, and a crankshaft balance weight. The cylinder assembly is arranged in the housing and defines a compression cavity and a balance cavity in the cylinder assembly. The crankshaft runs through the cylinder assembly, and the crankshaft has a main shaft section, an eccentric shaft section, an intermediate shaft section and a countershaft section connected to each other from top to bottom, wherein the eccentric shaft section has an eccentric portion, and the eccentric portion is located in the compression chamber. The driving motor is arranged in the casing, and the driving motor includes a stator and a rotor, the rotor is fixed to the main shaft section and a rotor balance weight is arranged on the end surface of the rotor. The piston is sleeved on the outside of the eccentric part. The crankshaft balance weight is sleeved on the intermediate shaft section and is located in the balance chamber, the crankshaft balance weight and the rotor balance weight are used to balance the eccentric part and the piston, and the crankshaft balance weight is formed in a cam shape. The rotary compressor of the invention has simple structure, small vibration and small deflection of the crankshaft.

Description

[0001] This application is a divisional application with an application date of March 14, 2013, an application number of 201310082579.6, and an invention title of "rotary compressor". technical field [0002] The invention relates to the field of compressor construction, in particular to a rotary compressor.
