Device to retain lubricant in a lubricating assembly and implementation thereof
View Patent ↗A lubricating assembly that is configured as part of a lubricating system that flings, or slings, fluid lubricants about the interior of rotating machinery. In one embodiment, the lubricating assembly includes a bearing clamp member with a clamp body having an outer peripheral edge that has an annular profile that partially circumscribes a longitudinal axis. The annular profile can have first annular section with a first clamp surface and a second clamp surface disposed in opposing relation about a centerline and spaced apart from one another to form a first annular gap. At the bottom of the clamp body, the bearing clamp member is configured with a peripheral wall that bounds a reservoir region. This configuration allows the fluid lubricants to gravity feed through the first annular gap into the reservoir region to retain a volume of the captured lubricant to lubricate moving parts of the lubricating system.
1. A lubricant reservoir component for a splash lubrication oil system, said lubricant reservoir component comprising:
a bearing clamp member having a clamp body with a top, a bottom, and an outer peripheral edge that forms an annular profile that circumscribes a central longitudinal axis, the clamp body having a first annular section forming a first opening in the annular profile at the top of the clamp body, the clamp body further having a first bore and a second bore aligned on the central longitudinal axis, the first bore forming an opening in the clamp body, wherein the first bore and the second bore have, respectively, a first diameter and a second diameter that is larger than the first diameter so as to form a first peripheral wall that bounds a reservoir region at the bottom of the clam body.
2. The lubricant reservoir component of claim 1 , wherein the clamp body has a first clamp surface and an opposing second clamp surface in the first annular section that are annularly spaced apart from one another to form the first opening at the top of the clamp body, wherein the first clamp surface and the second clamp surface taper downwardly in a direction from the outer peripheral edge toward the reservoir region.
3. The lubricant reservoir component of claim 1 , wherein the clamp body has a second annular section that is longitudinally adjacent to the first annular section along the central longitudinal axis, and wherein the second annular section forms a second opening in the annular profile.
4. The lubricant reservoir component of claim 3 , wherein the clamp body has a third clamp surface and an opposing fourth clamp surface in the second annular section that are annularly spaced apart from one another to form the second opening, and wherein the third clamp surface and the fourth clamp surface taper downwardly in a direction from the outer peripheral edge toward the reservoir region.
5. The lubricant reservoir component of claim 3 , wherein a linear distance between edges defining the second opening is larger than a linear distance between edges defining the first opening.
6. The lubricant reservoir component of claim 1 , further comprising a lubricant guide member that is configured to couple at the top of the bearing clamp member, wherein the lubricant guide member is configured to direct lubricant toward the reservoir region at the bottom of the clamp body.
7. The lubricant reservoir component of claim 6 , wherein the lubricant guide member comprises a body member and a pair of side members disposed on either side of a centerline, the side members forming a lubricant flow surface that tapers downwardly toward the bottom of the clamp body.
8. A compressor, comprising:
a splash lubricating system with a shaft member with a central longitudinal axis and a lubricant reservoir component configured to fit onto the shaft member, the lubricant reservoir component comprising a clamp body with a top, a bottom, and an outer peripheral edge that forms an annular profile that at least partially circumscribes the central longitudinal axis of the shaft member, the clamp body having a first bore with a first diameter and a second bore concentric with the first bore, the second bore having a second diameter, wherein the first diameter is less than the second diameter so as to from a first peripheral wall that bounds a reservoir region disposed at the bottom of the clamp body and at least partially below the shaft member and wherein the clamp body has a first clamp surface and an opposing second clamp surface that are annularly spaced apart from one another to form the first annular gap in the annular profile at the top of the clamp body.
9. The compressor of claim 8 , wherein the first clamp surface and the second clamp surface taper downwardly in a direction from the outer peripheral edge toward the reservoir region.
10. The compressor of claim 8 , wherein the clamp body has a third clamp surface and an opposing fourth clamp surface that are annularly spaced apart from one another to form a second annular gap in the annular profile.
11. The compressor of claim 10 , wherein the third clamp surface and the fourth clamp surface taper downwardly toward the reservoir region in a direction from the outer peripheral edge to the centerline.
12. The compressor of claim 10 , wherein a linear distance between edges defining the second opening is larger than a linear distance between edges defining the first opening.
13. The compressor of claim 8 , further comprising a bearing assembly with a bearing carrier member, wherein the clamp body is configured to couple with the bearing carrier member to position the bottom of the clamp body proximate the bearing carrier member, and wherein the bearing carrier member is configured to form a second peripheral wall that is spaced part from the first peripheral wall by the reservoir region.
14. The compressor of claim 13 , wherein the clamp body has one or more access holes that are configured to align with corresponding holes on the bearing clamp member.
15. The compressor of claim 14 , wherein the clamp body has a first side and a second side, wherein the second side is configured to reside proximate the bearing carrier member, wherein the first side has a least one relief that penetrates into the clamp body to a depth as measured from a first surface of the clamp body on the first side, and wherein the depth is configured to prevent a fastener disposed in the one or more access holes from protruding beyond the first surface of the clamp body on the first side.
16. The compressor of claim 8 , further comprising a lubricant guide member that is configured to couple at the top of the clamp body at points on each side of the first annular gap in the annular profile, the lubricant guide member configured to direct lubricant toward the reservoir region at the bottom of the clamp body.
17. The compressor of claim 16 , wherein the lubricant guide member comprises a body member and a part of side members disposed on either side of the centerline, the side members forming a lubricant flow surface that tapers downwardly towards the reservoir region at the bottom of the clamp body.
