Abstract

A bearing shell for a sliding bearing may include a body having a convex outer surface and an alignment feature projecting from the outer surface. The alignment feature may be arranged at an end face of the body. The alignment feature may include a first tapered portion having an axial width that reduces in a direction away from the end face. The first tapered portion may include at least two axial sides extending circumferentially and angled away from parallel with respect to a corresponding axial end face of the body by an angle of 2° to 10°.

First claim

The invention claimed is:

1. A bearing shell for a sliding bearing, comprising: a body having a convex outer surface and an alignment feature projecting from the outer surface, the alignment feature arranged at an end face of the body, wherein the alignment feature includes a first tapered portion having an axial width that reduces in a direction away from the end face, and wherein the first tapered portion includes at least two axial sides extending circumferentially and angled away from parallel with respect to a corresponding axial end face of the body by an angle of 2° to 10°.

2. The bearing shell according to claim 1 , wherein the angle of at least one of the at least two axial sides of the first tapered portion is from 3° to 7°.

3. The bearing shell according to claim 1 , wherein the alignment feature further includes:
a further portion proximal to the end face, and
wherein the first tapered portion is distal to the end face in relation to the further portion.

4. The bearing shell according to claim 3 , wherein the further portion is a second tapered portion, the second tapered portion having an axial width that reduces in a direction away from the end face of the body, and wherein the first tapered portion has a greater taper in an axial direction than the second tapered portion.

5. The bearing shell according to claim 3 , wherein the further portion has a constant axial width.

6. The bearing shell according to claim 1 , wherein the first tapered portion tapers in the direction away from the end face such that the at least two axial sides of the first tapered portion are axially spaced from one another.

7. The bearing shell according to claim 1 , wherein the first tapered portion has a circumferential length corresponding to at least half of a mean axial width defined by the first tapered portion.

8. The bearing shell according to claim 1 , wherein the alignment feature projects from the outer surface an extent that reduces along a circumferential length of the alignment feature in the direction away from the end face.

9. The bearing shell according to claim 1 , wherein the alignment feature extends circumferentially and defines an end face disposed substantially planar with the end face of the body.

10. The bearing shell according to claim 1 , wherein the alignment feature is spaced apart circumferentially from the end face of the body.

11. An engine, comprising: a housing and a bearing shell disposed in a recess defined by the housing, wherein the bearing shell includes:
a convex outer surface defined between at least two axial end faces and terminating at an end face;
an alignment feature projecting from the outer surface at the end face and disposed axially spaced from the at least two axial end faces, wherein the alignment feature includes a first tapered portion defining an axial extent that reduces in a direction away from the end face, the first tapered portion including two converging axial sides that are angled away from parallel with respect to the at least two corresponding axial end faces by an angle of 2° to 10°.

12. A method of manufacturing a bearing shell for a sliding bearing, comprising:
providing a body having a convex outer surface; and
forming an alignment feature projecting from the outer surface at an end face of the body, wherein the alignment feature includes a first tapered portion having an axial width that reduces in a direction away from the end face, and wherein the first tapered portion includes at least two axial sides extending circumferentially and angled away from parallel with respect to a corresponding axial end face of the body by an angle of 2° to 10°.

13. The method according to claim 12 , wherein forming the alignment feature includes at least one of a coining process, an embossing process, and a punching process.

14. The engine according to claim 11 , wherein the alignment feature further includes a second tapered portion proximate to the end face in relation to the first tapered portion, the second tapered portion defining an axial extent that reduces in the direction away from the end face, and wherein the first tapered portion defines a greater taper in an axial direction than the second tapered portion.

15. The engine according to claim 11 , wherein the alignment feature further includes a second portion proximate to the end face in relation to the first tapered portion, and wherein the second portion defines a constant axial extent.

16. The engine according to claim 11 , wherein the first tapered portion defines a circumferential extent corresponding to at least half of a mean axial extent of the first tapered portion.

17. The engine according to claim 11 , wherein the alignment feature projects a radial extent from the outer surface, wherein the radial extent reduces along a circumferential length in a direction away from the end face.

18. The engine according to claim 11 , wherein the alignment feature is circumferentially spaced from the end face of the body.

19. The engine according to claim 11 , wherein the angle of at least one of the axial sides of the first tapered portion is between 3° to 7°.

20. The engine according to claim 11 , wherein the alignment feature extends circumferentially and defines an end face disposed substantially planar with the end face of the body.
