Scroll machine having an axially compliant mounting for a scroll member

摘要

A scroll type machine is disclosed which incorporates an improved mounting arrangement for the non-orbiting scroll member which mounting arrangement greatly facilitates manufacturing and assembly, effectively prevents radial displacement of the non-orbiting scroll member, and offers the advantages of axial compliance. In one embodiment, the non-orbiting scroll is axially movably secured to a bearing housing by means of a plurality of bolts or bolts and sleeves. In another embodiment a rigid annular ring serves to axially movably secure the non-orbiting scroll to the bearing housing while in a third embodiment a stamped ring is secured to both the non-orbiting scroll and the bearing housing. In another embodiment a two piece main bearing housing includes an integral ring for radially positioning the non-orbiting scroll member and means for securing anti-rotation and axial stop means thereto. In yet another embodiment, a bayonet-type axially compliant mounting arrangement is provided for the non-orbiting scroll which provides integral stop means. Additionally, notches may be provided to isolate the mounting flanges of the two piece main bearing from the integral guide ring to avoid possible distortion thereof. A method of assembling and/or testing the compressor is also disclosed.
