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.

Claims20

Dependent claims

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.
