Problems solved by technology

In the prior art, no reliable fixing measures are taken in the axial direction of the crankshaft, so that the movement of the crankshaft in the axial direction cannot be well suppressed, resulting in poor stability of the rotor compressor during operation, and exacerbating zero Wear between parts, while creating noise problems

Abstract

The invention provides a compressor and an air conditioner. The compressor comprises a rotating shaft and an air cylinder. The rotating shaft penetrates through the air cylinder, the rotating shaft issleeved with a first flange, a second flange and a roller, the roller is located in the air cylinder, the first flange is arranged at the first end of the air cylinder in a covering manner, the second flange is arranged on the second end of the air cylinder in a covering manner, the roller is limited inside through the air cylinder, the first flange and the second flange, the roller is provided with a first limiting part, a crankshaft is provided with a second limiting part, the first limiting part and the second limiting part are matched, and a rotating shaft and the roller are fixed in theaxis direction of the rotating shaft. According to the compressor, moving of the crankshaft during work in the axial direction can be reduced, the compressor can more stably work, friction between parts can be reduced, and meanwhile, noise generated during work of the compressor can be reduced.

Description

technical field [0001] The application belongs to the technical field of air conditioning, and in particular relates to a compressor and an air conditioner. Background technique [0002] Existing rotary compressors include a driving power device and a compression device that lifts the refrigerant into high-pressure gas. The power device and the compression device are connected through the interference fit between the crankshaft and the motor rotor. The motor rotor drives the crankshaft to rotate, and then drives the roller to rotate in the cylinder to realize the work of the rotor compressor. [0003] When the compressor runs at high speed, the rotor of the motor is affected by the pressure pulsation, and it is easy to move in the axial direction, which in turn drives the crankshaft to move in the axial direction. In the prior art, no reliable fixing measures are taken in the axial direction of the crankshaft, so that the movement of the crankshaft in the axial direction ca...
