Abstract
A sliding surface bearings for heavy loads comprises a backing shell and a bearing metal layer provided on said backing shell and formed with axially spaced apart grooves, which extend at an acute angle of at most 15 degrees to the peripheral direction substantially around the axis of the bearing and contain a bearing which is softer than said bearing layer. In order to ensure that the bearing will have a long life, the axial center spacing of the grooves does not exceed an upper limit a.sub.o =250+0.5d+001 d.sup.2 where a.sub.o is expressed in micrometers and d is the diameter of the bearing surface in millimeters, and said center spacing in any case does not exceed 10 mm.
Claims8
In a sliding surface bearing for heavy loads, comprising
- a backing and
- a bearing metal layer carried by said backing and formed with a plurality of grooves, which contain a bearing material that is softer than said bearing metal layer and together with said bearing metal layer constitutes a bearing surface which is centered on an axis, wherein said grooves are spaced transversely to a peripheral direction related to said axis and substantially surround said axis and include with said peripheral direction an acute angle of up to 15 degrees,
- the improvement residing in that
- the center spacing of said grooves measured at right angles to said peripheral direction is not in exces of 10 millimeters and not in excess of an upper limit
- a.sub.o =250+0.5d+0.01d.sup.2
- where a.sub.o is expressed in micrometers and d is the effective diameter of said bearing surface in millimeters.
