Abstract

A compressor is provided and may include a shell having an inner surface and an outer surface and a bearing housing disposed within the shell and having an engagement surface opposing the inner surface. The engagement surface may include a first channel formed substantially perpendicular to a longitudinal axis of the shell and a second channel formed substantially parallel to the longitudinal axis of the shell and in communication with the first channel. The first channel and the second channel may receive a deformed portion of the shell therein to fix a position of the bearing housing relative to the shell.

First claim

What is claimed is:

1. A compressor comprising:
a shell having an inner surface and an outer surface; and
a bearing housing disposed within said shell and including an engagement surface opposing said inner surface, said engagement surface including a first channel and a second channel in communication with said first channel, said first channel extending further in a first direction than in a second direction such that a longitudinal axis of said first channel extends in said first direction without intersecting a longitudinal axis of said shell, said second channel extends from said first channel in said second direction, said first direction is substantially perpendicular to said longitudinal axis of said shell, said second direction is substantially parallel to said longitudinal axis of said shell, said first channel and said second channel receiving a deformed portion of said shell therein to fix a position of said bearing housing relative to said shell, wherein a maximum span of said first channel in said first direction is greater than a maximum span of said second channel in said first direction.

2. The compressor of claim 1 , wherein said second channel extends into and terminates at said first channel.

3. The compressor of claim 1 , wherein said second channel extends into and crosses said first channel.

4. The compressor of claim 1 , wherein said first channel and said second channel cooperate to form a substantially “T” shape.

5. The compressor of claim 1 , wherein said bearing housing includes at least two engagement surfaces opposing said inner surface, said at least two engagement surfaces each including said first channel and said second channel.

6. The compressor of claim 1 , wherein at least one of said first channel and said second channel are cast into said bearing housing.

7. The compressor of claim 1 , wherein both of said first channel and said second channel are cast into said bearing housing.

8. The compressor claim 1 , wherein said bearing housing includes at least two arms extending from a hub.

9. The compressor of claim 8 , wherein said first channel and said second channel are formed into a distal end of said at least two arms.

10. The compressor of claim 8 , wherein one of said at least two arms includes a different shape than the other of said at least two arms.

11. The compressor of claim 8 , wherein one of said at least two arms includes a projection extending from said one of said at least two arms toward an adjacent one of said at least two arms.

12. The compressor of claim 11 , wherein said projection includes a bore extending along a length of said projection.

13. The compressor of claim 12 , wherein said one arm of said at least two arms includes a support rib having a first width and the other of said at leasttwo arms includes a support rib having a second width, said first width being smaller than said second width.

14. The compressor of claim 12 , wherein said bore is an oil-drain hole.

15. The compressor of claim 12 , wherein said bore extends substantially parallel to a longitudinal axis of said projection and substantially perpendicular to said longitudinal axis of said shell.

16. A method comprising:
receiving a bearing housing inside of a compressor shell; and
deforming a portion of said compressor shell, after receiving said bearing housing inside of said compressor shell, to cause material from said compressor shell to flow into a first groove and into a second groove formed in said bearing housing,
wherein said first groove extends further in a first direction than in a second direction such that a longitudinal axis of said first groove extends in said first direction without intersecting a longitudinal axis of said compressor shell, said second groove extends from said first groove in said second direction, said first direction is substantially perpendicular to said longitudinal axis of said compressor shell, said second direction is substantially parallel to said longitudinal axis of said compressor shell.

17. The method of claim 16 , wherein said deforming said portion of said compressor shell causes said material of said compressor shell to simultaneously flow in opposite directions.

18. The method of claim 16 , wherein deforming said portion of said compressor shell forms a substantially T-shaped stake that fixes a position of said bearing housing relative to said compressor shell.

19. A compressor comprising:
a shell having an inner surface and an outer surface; and
a bearing housing disposed within said shell and including an engagement surface opposing said inner surface, said engagement surface including a first channel and a second channel in communication with said first channel, said first channel extending further in a circumferential direction than in an axial direction, said second channel extends from said first channel in said axial direction, said first channel and said second channel receiving a deformed portion of said shell therein to fix a position of said bearing housing relative to said shell, wherein a maximum span of said first channel in said circumferential direction is greater than a maximum span of said second channel in said circumferential direction, wherein said circumferential direction extends around a longitudinal axis of said shell, and wherein said axial direction extends parallel to said longitudinal axis of said shell.
