Abstract

Abstract A flanged bearing has a thin wall flexible bearing liner and end flanges formed as separate components. The flanges are attached to the liners by radial lugs on the inner peripheries of the flanges which engage in slots in the axial ends of the liner so that the curvature of the liner can vary with respect to the flanges. Outwardly projecting stakes are formed in the end edges of the liner to prevent the flanges disengaging axially from the liner while permitting limited axial float of the flanges with respect to the liner.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 53 words
A flanged half bearing comprising a thin wall flexible half bearing liner and a flange extending radially outwardly of at least one axial end of the liner wherein the improvement comprises attaching the flange to the liner by means which allow the circumferential shape of the liner to vary relative to the flange.
Claim 2
Dependent Claim 53 words
A flanged half bearing comprising a thin wall flexible half bearing liner and a flange extending radially outwardly of at least one axial end of the liner wherein the improvement comprises attaching the flange to the liner by means which allow the circumferential shape of the liner to vary relative to the flange.
Claim 3
Dependent Claim 53 words
A flanged half bearing comprising a thin wall flexible half bearing liner and a flange extending radially outwardly of at least one axial end of the liner wherein the improvement comprises attaching the flange to the liner by means which allow the circumferential shape of the liner to vary relative to the flange.
Claim 4
Dependent Claim 53 words
A flanged half bearing comprising a thin wall flexible half bearing liner and a flange extending radially outwardly of at least one axial end of the liner wherein the improvement comprises attaching the flange to the liner by means which allow the circumferential shape of the liner to vary relative to the flange.
Claim 5
Dependent Claim 34 words
A flanged half bearing as claimed in claim 1 wherein the attachment means permit relative movement of the flange with respect to the liner in a direction parallel to the axis of the liner.
Claim 6
Dependent Claim 24 words
A flanged half bearing as claimed in claim 1 wherein one of the said flanges is provided at both axial ends of the liner.
Claim 7
Dependent Claim 54 words
A flanged half bearing as claimed in claim 1 wherein the flange encircles said axial end of the liner and the attachment means comprise a plurality of lugs spaced apart around the inner periphery of the flange and a plurality of corresponding slots in the end of the liner in which the lugs engage.
Claim 8
Dependent Claim 29 words
A flanged half bearing as claimed in claim 4 wherein three lugs are provided at spaced locations which engage in three corresponding slots in the end of the liner.
Claim 9
Dependent Claim 46 words
A flanged half bearing as claimed in claim 4 wherein radially outwardly projecting abutment means are provided at the end of the liner to prevent the flange from disengaging axially from the liner whilst permitting limited axial movement of the flange with respect to the liner.
Claim 10
Dependent Claim 32 words
A flanged half bearing as claimed in claim 6 wherein the abutment means comprise a number of separate abutments located at the edge of the liner On either side of each slot.
Claim 11
Dependent Claim 25 words
A flanged half bearing as claimed in claim 6 wherein the abutment means comprises a lip around said end of the liner between the slots.
Claim 12
Dependent Claim 38 words
A flanged half bearing as claimed in claim 4 wherein the inner periphery of the end portion of the liner is chamfered and the sides of the lugs which face axially away from the liner are also chamfered.
Claim 13
Dependent Claim 26 words
A flanged half bearing as claimed in claim 1 wherein the liner and flange each comprise a backing and a layer or layers of bearing material.
Claim 14
Dependent Claim 19 words
A flanged half bearing as claimed in claim 10 wherein the flange and liner have backings of different thickness.
Claim 15
Dependent Claim 25 words
A flanged half bearing as claimed in claim 10 wherein the layers of bearing material on the liner and the flange are of different thickness.
