Abstract
Sliding-type bearings are locally welded along only edge regions of the backing to the components in which they are installed. Welding is controlled to isolate the bearing layer from the heat effected zone of welding.
Claims20
A combination of a component and a sliding bearing for supporting a member for movement relative to said component, said combination comprising:
- a metal backing of the bearing having a convex outer surface and a concave inner surface extending longitudinally between opposite ends and laterally between opposite edge regions of said backing;
- at least one layer of a relatively softer bearing material applied to said concave inner surface of said backing;
- a concave seat of said component supporting said convex outer surface of said metal backing;
- said backing being edge welded only along said edge regions to said component for securing said bearing to said component, and said edge regions of said backing extending laterally beyond said bearing material.
1 more element
A method of joining a sliding bearing to a component, comprising:
- providing a concave bearing seat in the component;
- positioning a convex outer surface of a metal backing of the sliding bearing against the concave bearing seat of the component with at least one layer of bearing material being bonded to a concave inner surface of the backing;
- and
- welding only lateral edge portions of the backing to the component defining edge welds which are spaced across a central region of the backing between the edge welds, and isolating the bearing metal from any heat affected zone resulting from welding.
