Title:
SCROLL COMPRESSOR AND POSITIONING METHOD FOR USE IN STATIC SCROLL COMPONENT OF SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/108232
Kind Code:
A1
Abstract:
A scroll compressor and a positioning method for use in a static scroll component of the scroll compressor. The scroll compressor comprises: a housing (13), a compressing mechanism, and a main bearing base (14, 24, and 34). The compressing mechanism comprises the static scroll component (12, 22, and 32). The static scroll component (12, 22, and 32) comprises a substrate and a circumferential wall extending downwards from the substrate. The circumferential wall of the static scroll component (12, 22, and 32) is provided on the periphery of a scroll of the static scroll component (12, 22, and 32). The main bearing base (14, 24, and 34) is adapted to support the compressing mechanism. Either a circumferential annular groove (145, 245, and 345) or a protruding part is provided at where an inner circumferential wall of the housing (13) is located, at where the inner circumferential surface of the main bearing base (14, 24, and 34) is located, or at where the housing (13) and/or the main bearing base (14, 24, and 34) is fixedly connected to the inner circumferential surface of a fixing component; moreover, the other of the circumferential annular groove (145, 245, and 345) and the protruding part is provided at where an outer circumferential wall of the static spiral component (12, 22, and 32) is located. The protruding part is interference fitted in the axial direction into the circumferential annular groove (145, 245, and 345). The employment of the compressor and of the positioning method reduces the number of components, saves space in the radial direction, favors the control of the axial floatation of the static scroll component, and makes the assembly and disassembly of the compressor easy and reliable.
