Compressor

Abstract

The invention provides a compressor, which comprises a spindle (15), wherein a gravity center adjusting mechanism (7) is arranged on the spindle (15); the gravity center adjusting mechanism (7) can rotate along with the spindle (15); and the center of gravity of the gravity center adjusting mechanism (7) can generate movement in the axial direction of the spindle during rotation. According to thecompressor, the center of gravity can be automatically adjusted along with the rotation of the spindle, the self-adaptive dynamic adjustment effect can be generated along with the change of the operating frequency of the compressor, the vibration of the compressor during operation is effectively reduced, and the center of gravity of a compressor shaft system is adaptively reduced, so that the compressor runs at high frequency more stably, the vibration is small and the noise is low; the center of gravity of the compressor shaft system is reduced and the stress on the upper part of the compressor is indirectly reduced, so that the vibration of a suction and exhaust pipe is reduced, and a problem that the vibration of the shaft system is large during operation of the compressor is solved; and furthermore, a problem that the vibration of the compressor during operation is greatly increased along with the increase of the frequency is solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor. Background technique [0002] Scroll compressors are widely used in the fields of refrigeration, air conditioning and heat pumps because of their high efficiency, small size, light weight, and stable operation. Generally speaking, a scroll compressor is composed of a closed shell, a fixed scroll, a movable scroll, a bracket, a main shaft, an oil supply device for an anti-rotation mechanism, and a motor. The profiles of the movable and static scrolls are both spiral , The movable scroll is installed eccentrically with respect to the static scroll with a difference of 180°, so multiple crescent-shaped spaces are formed between the movable and static scrolls. When the movable scroll takes the center of the static scroll as the center of rotation and performs non-rotation-translational motion with a certain radius of rotation, the crescent-shaped space of the outer...

Problems solved by technology

[0011] Therefore, the technical problem to be solved by the present invention is to overcome the structure such as the compressor balance block in the prior art that cannot realize the self-adaptive dynamic adjustment effect with the change of the operating frequency of the compressor, resulting in the large vibration of the compressor during operation defects, thus providing a compressor
