Problems solved by technology

Because this solution is grooved on the inner peripheral surface of the rotor center shaft hole, the force arm relative to the rotation center is too small, and its effect of replacing the rotor balance weight is very limited (the rotor balance weight is usually arranged on the outer peripheral side of the rotor, and the force arm is larger. When overcoming the same centrifugal force, the required mass is smaller), thinking about the balance effect of the equivalent balance weight means that a larger gap volume needs to be set, which will affect energy efficiency, and because it runs through the central axis of the rotor, There is a tendency to deteriorate the fixing strength of the rotor and the crankshaft

Abstract

The invention discloses a compressor which comprises a shell, a pump body and a driving motor. The pump body is arranged in the shell, the pump body is provided with a crankshaft, and the crankshaft is provided with an eccentric part; the driving motor is arranged in the shell and used for driving the pump body, and comprises a stator and a rotor, wherein the rotor is provided with a rotor outer peripheral surface and a rotor end surface, and a notch part is formed at the junction of the rotor outer peripheral surface and the rotor end surface, so that the rotor can balance the eccentric partby the notch part. According to the compressor, the wind friction loss is small, the system efficiency is high, the production process is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a high-speed compressor. Background technique [0002] The eccentricity of the eccentric part on the compressor crankshaft determines the volume of the compressor. When the compressor is running, the centrifugally rotating eccentric part will significantly increase the vibration and noise of the compressor. In order to balance the eccentricity of this part during operation, the The vibration and noise of the rotor are usually equipped with balance blocks on the upper and lower end faces of the rotor to balance the rotation of the mechanical part. In the existing known technology, counterbore holes are set inside the rotor to realize the self-balancing of the rotor, so as to reduce the amount of corresponding balance blocks. The latest prior art "rotary compressor and its motor assembly CN201520288984", which is provided with a central shaft hole axially penetrating the rotor ...
