Compressor core flexible supporting structure

Abstract

The invention discloses a compressor core flexible supporting structure. The compressor core flexible supporting structure comprises a gasket, an elastic element, an upper bush, a lower bush and a convex nail; the gasket is arranged at the upper end of the upper bush, the lower bush is arranged on the convex nail in a sleeving manner, the lower portion of the elastic element is arranged on the lower bush in a sleeving manner, the upper bush is inserted in the upper portion of the elastic element, an overlapping area is arranged between the lower portion of the upper bush and the upper portionof the lower bush, and the lower portion of the upper bush and the upper portion of the lower bush have a certain gap in the overlapping area. The flexible supporting structure is adopted to reduce connection rigidity between a compressor core and a shell, the effect of reducing compressor vibration is achieved, and shell crashing during compressor starting can be avoided.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a flexible support structure used between the internal core and the shell of a hermetic refrigeration compressor. Background technique [0002] Refrigeration compressors are installed on domestic or commercial refrigerators or freezers. When working, the refrigerant enters the refrigeration system through the suction pipe, suction muffler, cylinder, exhaust chamber, inner exhaust pipe, and exhaust pipe. During this process, the piston will reciprocate, thereby causing the movement to vibrate, and the vibration is transmitted to the casing along the support structure of the movement and the inner row pipe. The existing movement support structure generally includes a gasket, an upper bush, a spring, a lower bush and a convex nail, and the vibration of the movement along the support structure is mainly damped by the spring. Usually, technicians reduce the vibration of the comp...

Problems solved by technology

However, as the spring stiffness decreases, the displacement of the movement will become larger and larger when starting, and the compressor will crash into the case in severe cases.
