Interlocking bearing
A modular plain bearing is provided. The modular plain bearing includes a first end portion having a terminal edge with a plurality of first fingers and a second end portion having a terminal edge with a plurality of second fingers. The plurality of fingers cooperatively engage to provide a snap fit connection between the parts. For longer plain bearings, a bearing extender is provided. The bearing extender includes at least a first connector having a plurality of first connector fingers. The bearing extender may include either a second connector opposite the first connector having a plurality of second connector fingers.
1. A flanged modular plain bearing, comprising:
a first end portion having a longitudinal axis and a transverse axis, the first end portion comprising a radially extending flange with an external surface, an internal surface, and a circular opening, and a straight cylindrical bearing wall that extends from the internal surface to a first end portion edge, the first end portion having a plurality of first fingers proximate the first end portion edge, and wherein the internal surface of the straight cylindrical bearing wall is flush with the opening in the flange; and
a second end portion releasably coupled to the first end portion, the second end portion having a longitudinal axis and a transverse axis, the second end portion comprising a bearing wall that extends from a first end to a second end portion edge, the second end portion having a plurality of second fingers proximate the second end portion edge, wherein
the plurality of first and second fingers extend along the longitudinal axis and are chamfered at the first and second end portion edges, such that when pushed together during assembly, the first and second fingers are flexed and moved over one another in transverse direction to cooperatively engage in a snap fit.
2. The flanged modular plain bearing of claim 1 , wherein the second end portion further comprises a radially extending flange at said first end.
3. The flanged modular plain bearing of claim 1 , wherein the second end portion further comprises a terminal wall.
4. The flanged modular plain bearing of claim 1 , wherein the first end portion and the second end portion are identical.
5. The flanged modular plain bearing of claim 1 , wherein the first end portion and the second end portion are non-identical.
6. The flanged modular plain bearing of claim 1 , wherein the first end portion comprises a bore.
7. The flanged modular plain bearing of claim 1 , wherein the plurality of first fingers and the plurality of second fingers are evenly spaced around the bearing wall.
8. The flanged modular plain bearing of claim 1 , wherein the plurality of first fingers and the plurality of second fingers are unevenly spaced around the bearing wall.
9. The flanged modular plain bearing of claim 1 , wherein the first end portion and the second end portion are formed from a polymer.
10. The flanged modular plain bearing of claim 9 , wherein the first end portion and the second end portion are formed by injection molding.
