Abstract

A compressor assembly comprising a housing having a shaft bore therein, a main shaft positioned for rotation within the shaft bore, at least one roller thrust bearing and a thurst surface bearing clip. The thrust surface bearing clip comprises a first position configured for fixed engagement with the housing and a second portion extending from the first portion and configured for supporting a thurst surface in a position spaced from the rotating shaft, the thrust surface providing a bearing surface for the roller thrust bearing.

Claims (20)

1. A compressor assembly comprising:

a housing having at least one bore therein;

a main shaft positioned for rotation within the bore;

at least one roller thrust bearing;

a thrust surface bearing clip comprising:

a first portion configured for fixed engagement with the housing; and

a second portion extending from the first portion and configured for supporting a thrust surface in a position spaced from the shaft, the thrust surface providing a bearing surface for the roller thrust bearing; and

a radial bearing positioned in the shaft bore between the shaft and the housing wherein the radial bearing includes a bearing race with an axial lip extending therefrom, the bearing race defining the first portion and the axial lip defining the second portion.

2. The compressor of claim 1 wherein the lip is an annular lip.

3. The compressor of claim 1 wherein the lip is defined by a plurality of spaced tabs.

4. A compressor assembly comprising:

a housing having at least one bore therein;

a main shaft positioned for rotation within the bore;

at least one roller thrust bearing; and

a thrust surface bearing clip comprising:

a first portion configured for fixed engagement with the housing; and

a second portion extending from the first portion and configured for supporting a thrust surface in a position spaced from the shaft, the thrust surface providing a bearing surface for the roller thrust bearing;

wherein the first portion is defined by a cup body press fit in the shaft bore and the second portion is defined by a lip extending from the body.

5. The compressor of claim 4 wherein the lip is an annular lip.

6. The compressor of claim 4 wherein the lip is defined by a plurality of spaced tabs.
