Abstract
A scroll type machine is disclosed which is designed to enable it to be fully assembled prior to being installed in a hermetic shell and incorporates an improved mounting arrangement for the non-orbiting scroll member. This design enables the compressor to be tested without the need to first install it in the outer shell. This feature in combination with the mounting arrangement greatly facilitates manufacturing, assembly, testing, 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. A method of assembling and/or testing the compressor is a…
