Main bearing pedestal for scroll compressor, and scroll compressor

Abstract

The invention relates to a main bearing pedestal for a scroll compressor, and the scroll compressor. On one hand, a main bearing pedestal (100) for the scroll compressor (10) is disclosed, the main bearing pedestal comprises thrust parts (120A, 120B, 120C) which are used for supporting a compression mechanism of the scroll compressor and are in the shape of a roughly circular ring, and a main bodypart (140) which is provided with a bearing so as to support a driving shaft of the scroll compressor, wherein a plurality of suspension parts extending along a radial direction of the scroll compressor are arranged in the thrust parts (120A, 120B, 120C), and moreover, the suspension parts are arranged along an axial direction (L) of the scroll compressor. The main bearing pedestal provided by the invention can adjust the rigidity of the thrust parts so as to realize rigidity match and deformation coordination with a bottom surface of a dynamic vortex better, consequently, increases an effective contact area at a contact side of a thrust surface to obtain more uniform contact stress distribution and reduce abrasion, and moreover, provides a proper gap at a non-contact side so as to facilitate lubrication.

Description

technical field [0001] The present invention relates to a main bearing housing for a scroll compressor and a scroll compressor including the main bearing housing. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] A scroll compressor generally includes a compression mechanism composed of a fixed scroll component and a movable scroll component to achieve fluid compression. The orbiting scroll is supported by a main bearing housing or a thrust plate to provide axial restraint. The thrust design of the existing orbiting scroll part and main bearing seat or thrust plate is especially suitable for the heavy-duty working condition of the scroll compressor, for example, in the operating condition "60 / 150 / 20 / 15-60Hz ( Among them, 60 is the evaporating temperature, 150 is the condensation temperature, 20 is the degree of superheat, and 15 is the degree of sub...

AI Technical Summary

Problems solved by technology

When using a special refrigerant such as R32, the temperature of the thrust surface will reach, for example, 160 degrees Fahrenheit or even higher, which is much higher than the temperature using common refrigerants, resulting in the thrust surface of the orbiting scroll part and the thrust plate Deterioration of lubrication between the orbiting scroll and the thrust surface of the thrust plate
