Scroll compressor lower bearing supporting structure

Abstract

The invention relates to a scroll compressor lower bearing supporting structure comprising a low-pressure chamber and a high-pressure chamber arranged in the compressor. A motor is arranged in the middle of the low-pressure chamber. The motor is connected with an eccentric crankshaft. The upper end and the lower end of the eccentric crankshaft are respectively supported by an upper bearing and a lower bearing. The lower bearing is connected with a lower bearing support. The lower bearing and the lower bearing support are connected through the interference fit of the outer circumference of the lower bearing and the inner circumference of the lower bearing support. According to the scroll compressor lower bearing supporting structure, the lower bearing is directly pressed into the lower bearing support. When the lower bearing and the lower bearing support are assembled, a special fixture necessary for ensuring the concentricity of the two is eliminated, and the diameter and end face height of the lower bearing can be greatly reduced. According to the invention, assembly time is reduced, the cost for manufacturing the special fixture is saved, material for the lower bearing is saved, and the manufacturing cost of the scroll compressor is greatly reduced.

Description

technical field [0001] The invention relates to a supporting structure of a compressor, in particular to a lower bearing supporting structure of a scroll compressor. [0002] The invention relates to an assembly method of compressor components, in particular to an assembly method of a lower bearing support structure of a scroll compressor. Background technique [0003] Generally speaking, a compressor is a part of a refrigeration cycle device, and it is a device that pressurizes a refrigerant to make the pressure and temperature of the refrigerant suitable for a specific purpose. The refrigeration cycle device consists of a compressor, a condenser, an expansion device, and an evaporator, and all components are connected to each other to form a closed circulation system. [0004] This refrigeration cycle device compresses the low-temperature and low-pressure refrigerant gas sucked into the compressor, and discharges it in a high-temperature and high-pressure state. When the ...

Problems solved by technology

[0010] The present invention is to solve the problem of the prior art that the assembly process of the lower bearing and the lower bearing bracket of the scroll compressor is complex; the technical level of the assembly workers is high; the assembly process needs to be specially manufactured to ensure the concentricity of the lower bearing and the lower bearing bracket The special fixture, and the concentricity is still difficult to guarantee, the assembly work efficiency is low and other technical problems, but to provide a scroll compressor lower bearing support structure that simply and quickly assembles the lower bearing and the lower bearing bracket together
