MECHANISM AND METHOD FOR ALIGNING A FIXED SCROLL IN A SCROLLCOMPRESSOR

摘要

A method and mechanism for aligning a fixed scroll member relative to a main bearing member in a scroll compressor. A shoulder is machined on the ou ter perimeter of a main bearing member and interfits with an arcuate lip on the fixed scroll member to thereby center the fixed scroll member. A notch is machined into the arcuate lip of the fixed scroll member and receives a projecting pin dis posed on the main bearing member when the fixed scroll is assembled to the main beari ng member. Relative rotation of the fixed scroll member and main bearing member brings one edge of the projecting pin into engagement with an abutment surfa ce defining one end of the notch and thereby properly rotationally positioning the fixed scroll member. The fixed scroll member is subsequently axially secured to th e main bearing member with a plurality of bolts.
