Abstract

A lubricant assembly that is configured as part of a lubricating system that flings, or slings, fluid lubricants about the interior of compressors. In one embodiment, the lubricant assembly includes a lubricant guide member with a body member that has a pair of peripheral side members with angled surfaces. The construction is amenable to more consistent fabrication constraints (e.g., tolerances), as well as to offer features that can improve operation of the lubricating system, e.g., as operative in the compressors. In use, the lubricant guide member is disposed transverse to a longitudinal axis of a shaft that is configured to rotate a slinger member to fling the lubricant. This configuration captures lubricant that falls downwardly from other parts of the compressors. The angled surfaces of the side members direct this captured lubricant toward the shaft, and other rotating components, of the lubricating system.

Claims (23)

1. A lubricant guide member for a splash lubrication oil system, said lubricant guide member comprising:

a body member having a first side, a second side, a longitudinal axis, and a centerline extending radially from the longitudinal axis, the body member comprising a primary attachment feature that forms openings disposed in a direction of the longitudinal axis; and

side members comprising a first side member and a second side member coupled with the body member and disposed on either side of the centerline, the first side member and the second side member comprising a first member and a second member, the first member coupled with the body member and extending transversely away from the body member on the second side along the longitudinal axis, the second member coupled with the first member and spaced apart from the body member along the longitudinal axis, the second member extending in a direction along the centerline toward the longitudinal axis, wherein the first member comprises a lubricant flow surface disposed at an angle with respect to each of the longitudinal axis and the centerline such that the lubricant flow surface defines a substantially straight linear slope extending inwardly towards the centerline and downwardly towards a bottom of the body member.

2. The lubricant guide member of claim 1 , wherein the first member is formed integrally with the body member.

3. The lubricant guide member of claim 2 , wherein the second member is formed integrally with the first member.

4. The lubricant guide member of claim 1 , further comprising one or more stress relief features at a corner at which the first member couples with the body member.

5. The lubricant guide member of claim 4 , further comprising a tab member adjacent the stress relief feature, wherein the tab member extends from the first member towards the centerline.

6. The lubricant guide member of claim 5 , wherein the tab member extends toward the centerline at an angle away from the longitudinal axis.

7. The lubricant guide member of claim 5 , wherein the tab member is disposed on the first side of the body member.

8. The lubricant guide member of claim 1 , wherein the first side member and the second side member are disposed symmetrically about the centerline.

9. The lubricant guide member of claim 1 , wherein the primary attachment feature comprises a pair of thru-holes spaced from the centerline.

10. The lubricant guide member of claim 1 , wherein the second member of the side members defines a secondary attachment feature that forms openings disposed in the direction of the longitudinal axis.

11. The lubricant guide member of claim 10 , wherein the secondary attachment feature comprises a pair of thru-holes spaced from the centerline.

12. A compressor, comprising:

a splash lubricant oil system comprising a shaft member and a lubricant guide member extending circumferentially over at least part of the shaft member, the lubricant guide member comprising a body member having a top and a bottom proximate the shaft member, the body member comprising a central portion with a first side, a second side, and side members comprising a first side member and a second side member disposed on either side of a centerline bisecting the central portion, each side member having a first member and a second member, the first member coupled with the central portion and comprising a first part extending perpendicularly away from the second side of the central portion, the second member coupled with and extending downwardly from the first member along the centerline toward the bottom of the body member, wherein the first member comprises a lubricant flow surface disposed at a first angle with respect to each of the longitudinal axis and the centerline that configures the lubricant flow surface to direct lubricant towards the shaft member, wherein the lubricant flow surface defines a substantially straight linear slope extending inwardly towards the centerline and downwardly towards a bottom of the body member.

13. The compressor of claim 12 , wherein the first member is formed integrally with the body member.

14. The compressor of claim 13 , wherein the second member is formed integrally with the first member.

15. The compressor of claim 12 , wherein the first member has a second part that extends perpendicularly away from the central portion in a direction towards the first side, the second part forming a tab member proximate the corner, and wherein the tab member extends from the second part towards the centerline at a second angle away from the longitudinal axis.

16. The compressor of claim 15 , wherein the body member incorporates a fillet with a radius forming a corner at which the first member adjoins the central portion in each of the first side member and the second side member.

17. The compressor of claim 12 , wherein the second member is spaced apart from the central portion as measured between a first plane that is tangent to at least two points on the first side of the second member and a second plane tangent to at least two points on the first side of the central portion.

18. The compressor of claim 17 , wherein the first plane is parallel to the second plane.

19. The compressor of claim 12 , wherein the body member is configured with a plurality of through-holes comprising a first set of through-holes disposed in the central portion proximate the bottom of the body member and a second set disposed in the second member.

20. The compressor of claim 19 , wherein the splash lubricant oil system comprises a bearing assembly with a bearing carrier member, and wherein the first set of through holes are configured to align with holes on the bearing carrier member.
