Title:
METHOD FOR MANUFACTURING SCROLL COMPRESSOR AND SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/145185
Kind Code:
A1
Abstract:
This method is for manufacturing a scroll compressor (101) provided with: a compression mechanism part (3) having a fixed scroll (31) and an oscillation scroll (32); and a main frame (2) that slidably holds the oscillation scroll (32). The method includes: a step for inserting the main frame (2) along an inner wall of a tubular molded main shell (11) and performing positioning by bringing a positioning part (protrusion (216)) of the outer circumference of the main frame 2 into contact with a second positioning surface (116) of a stepped part annularly provided to the inner wall; and a step for fixing the main frame (2) by input of heat while cooling a power supply part (8) provided to the outer circumference of the main shell (11). By performing local cooling, restrictions on distances between components are eased and cost is reduced.
