Title:
MAIN BEARING SEAT FOR SCROLL COMPRESSOR, AND SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/215724
Kind Code:
A1
Abstract:
Disclosed are a main bearing seat (100) for a scroll compressor (10), and a scroll compressor (10). The main bearing seat (100) comprises substantially ring-shaped thrust parts (120A, 120B, 120C) for supporting a compressing mechanism of the scroll compressor (10), and a main part body (140) provided with a bearing to support a driving shaft (50) of the scroll compressor (10), wherein multiple suspension parts extending in a radial direction of the scroll compressor (10) are provided in the thrust parts (120A, 120B, 120C), and the suspension parts are arranged in an axial direction (L) of the scroll compressor (10). The main bearing seat (100) can adjust the stiffness of the thrust parts (120A, 120B, 120C) to better achieve stiffness matching and deformation coordination with a bottom face of a movable vortex (200), thereby increasing the effective contact area on a contact side of a thrust surface to achieve more uniform contact stress distribution and reduce the wear, and providing an appropriate gap on a non-contact side to facilitate lubrication.
