Self-adaptive dynamic vortex plate eccentric mechanism

Abstract

The invention relates to a self-adaptive dynamic vortex plate eccentric mechanism comprising a transmission shaft assembly, a dynamic vortex plate and a static vortex plate. When a transmission shaftis in the static state, a slider is located at a first eccentric position; when the transmission shaft is in the rotating state, the centrifugal effect enables the slider to overcome spring force to slide outward in the radial direction to a second eccentric position; the first eccentric position is closer to the rotation center of the transmission shaft than the second eccentric position. The outer end of the slider is the drive end of the dynamic vortex plate. Eccentric radial sliding of the slider can cause the relative position between the dynamic vortex plate and the static vortex plate to change, and in other words, eccentric radial sliding of the slider enables the dynamic vortex plate to conduct synchronous radial and eccentric movement. The self-adaptive dynamic vortex plate eccentric mechanism adopts the mechanical self-adaption manner, ingeniously achieves unloading of the starting load feature of a scroll compressor, effectively lowers the starting load and achieving a goodeffect on the starting performance of the compressor.

Description

technical field [0001] The invention relates to the field of compressors, in particular to an adaptive movable scroll eccentric mechanism, in particular to an adaptive movable scroll eccentric mechanism for a fixed-frequency scroll compressor. Background technique [0002] The compressor is a fluid machine. In the refrigeration system, the compressor realizes the refrigeration function of the refrigeration system by compressing the low-pressure gas into a high-pressure gas to promote the circulation of the refrigerant. A scroll compressor is a type of positive displacement compressor. In a hermetic compressor, the motor, as a part of the compressor, is coupled with the pump body through a drive shaft and integrated inside the casing. It mainly consists of motor assembly (1), housing assembly (2), drive shaft assembly (3), support frame assembly (4), movable scroll (5), fixed scroll assembly (6), end cover assembly ( 7), bearings (8, 12, 13), anti-rotation ring (9), friction...
