Problems solved by technology

The ensuing problem is that due to the unbalanced electromagnetic tension in the motor gap, the crankshaft of the compressor is elastically deformed at the moment of starting, causing the rotor to collide with the inner diameter of the stator.
At the same time, the increase of the motor speed increases the centrifugal force of the rotor, and the end of the rotor and the inner diameter of the stator often scrape and collide, and the swing of the crankshaft will increase the wear between the crankshaft and the compression assembly, which will eventually increase the noise

Abstract

The invention discloses a rotary compressor which comprises a housing, a driving motor, a compressing mechanism and a supporting component. The driving motor is arranged inside the housing and comprises a stator and a rotor which is rotatablely arranged inside the stator. The compressing mechanism is disposed inside the housing and contains a compression component and a crankshaft. The compression component is fixed on the housing and at least comprises an air cylinder component. The supporting component is arranged inside the housing and is positioned at one side of the driving motor, far from the compression component. The supporting component is fixed on the housing and is in supporting fit with one end of the crankshaft that passes through the rotor. The rotary compressor is configured under the following condition: Q/D is less than or equal to 22 cm<2> and greater than or equal to 10 cm<2>, wherein Q is displacement of the rotary compressor, and D is shaft diameter of a main shaft section of the crankshaft positioned at one side of the air cylinder component near the driving motor. According to the rotary compressor, assembly accuracy is raised, and collision between rotor and stator bore is reduced as well as abrasion between the crankshaft and the compression component. Thereby, performance and reliability of the compressor are enhanced.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a rotary compressor. Background technique [0002] With the development of compressor technology and the improvement of high efficiency requirements, the height of the rotary compressor motor is gradually increased, the motor speed is getting higher and higher, the diameter of the crankshaft is getting smaller and smaller, the ratio of length to diameter is getting bigger, and the rigidity of the crankshaft is getting higher and higher. The worse it is, the ability to resist deformation is gradually reduced. The ensuing problem is that due to the unbalanced electromagnetic tension in the motor gap, the crankshaft of the compressor is elastically deformed at the moment of starting, causing the rotor to collide with the inner diameter of the stator. At the same time, the increase of the motor speed will increase the centrifugal force of the rotor, and the end of the rotor will often scr...
