Abstract
Official abstract text for this publication.
A plain bearing comprising a generally cylindrical sidewall having a first axial end and a second axial end; and a curved portion disposed at the first axial end, wherein the generally cylindrical sidewall has a thickness, wherein the curved portion has an effective material thickness, wherein the effective material thickness of the curved portion is n-times thicker than the thickness of the generally cylindrical sidewall, and wherein n equals 2, 3, 4, or even 5.
First claim
Opening claim text (preview).
The invention claimed is: 1. A plain bearing comprising: a cylindrical sidewall having a first axial end and a second axial end; and a curved portion disposed at the first axial end, wherein the cylindrical sidewall has a thickness, wherein the curved portion has an effective material thickness, wherein the effective material thickness of the curved portion is n-times thicker than the thickness of the cylindrical sidewall, and wherein n equals 2, 3, 4, or 5, wherein the curved portion comprises a substrate and a low friction material, wherein the curved portion defines a cavity extending at least partially around the circumference of the plain bearing, and wherein the cavity is fully bounded by the substrate. 2. The plain bearing of claim 1 , wherein the cylindrical sidewall comprises a gap extending at least partially between the first and second axial ends. 3. The plain bearing of claim 1 , wherein the curved portion has a plurality of rolls, and wherein at least two of the plurality of rolls are coaxial with respect to one another. 4. The plain bearing of claim 1 , wherein the curved portion has at least two tangent lines, when viewed in cross section, parallel to the cylindrical sidewall. 5. The plain bearing of claim 1 , wherein the cavity has an assembled shape after assembly. 6. The plain bearing of claim 1 , wherein the cavity defines a second volume after assembly. 7. The plain bearing of claim 1 , wherein the cylindrical sidewall comprises a substrate and a low friction material. 8. A plain bearing comprising: a cylindrical sidewall; and a curved portion contiguous with an extending from an axial end of the cylindrical sidewall, wherein: the bearing comprises a low friction material and a substrate, the substrate is exposed along a radially outer surface of the cylindrical sidewall, and the substrate is not visible along the curved portion, wherein the curved portion has an effective material thickness, wherein the effective material thickness of the curved portion is n-times thicker than the thickness of the cylindrical sidewall, and wherein n equals 2, 3, 4, or 5, wherein the curved portion comprises the substrate and the low friction material, wherein the curved portion defines a cavity extending at least partially around the circumference of the plain bearing, and wherein the cavity is fully bounded by the substrate. 9. The plain bearing of claim 8 , wherein the cylindrical sidewall comprises a gap extending at least partially between the first and second axial ends. 10. The plain bearing of claim 8 , wherein, as viewed in a cross-sectional elevation view, the curved portion has a arcuate innermost surface. 11. The plain bearing of claim 8 , wherein the curved portion has at least 3 rolls. 12. The plain bearing of claim 8 , wherein the curved portion has a plurality of rolls, and wherein at least two of the plurality of rolls are coaxial with respect to one another. 13. The plain bearing of claim 8 , wherein the curved portion has at least two tangent lines, when viewed in cross section, parallel to the cylindrical sidewall.
