Abstract
Abstract A resilient bearing bushing or insert intended for use between a rotatingly or slidingly operating cylindrical shaft and a housing for the shaft, the bearing having a body structure particularly constructed to hold the shaft resiliently in the housing by way of point, linear or partial surface contact therewith. The bearing comprising alternately in the circumferential direction a smaller radius point circumscribing the shaft and radially inwardly spaced from the inner cylindrical wall of the housing and a larger radius point inscribing the inner cylindrical wall of the housing and radially outwardly spaced from the circumference of the shaft, said larger radius point forming axially extending longitudinal outer projections along the entire length of the bearing body.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
205 words
A resilient bearing bushing for use between a rotatingly or slidingly operating cylindrical shaft and a cylindrical housing for said shaft, said resilient bearing bushing comprising a generally tubular body having three arcuate side walls and three arcuate vertices, said side walls each having inner surfaces which are arcuate along their entire circumferential extent, each of said inner arcuate surfaces having a central, circumferential portion constituting a major portion of said arcuate inner surface, said central, circumferential portion resiliently pressed against a corresponding circumferential portion of said shaft, said side walls each having outer surfaces which are arcuate along their entire circumferential extent and which are radially spaced from the inner periphery of said cylindrical housing, said vertices having outer surfaces resiliently pressed against the inner periphery of said cylindrical housing and inner surfaces spaced from the circumference of said shaft, said tubular body having three recesses formed on the inner surface of said tubular body in positions corresponding to said vertices, said recesses having a wall thickness smaller than the thickness of the remaining portions of the tubular body such that the thickness of said tubular body at said vertices is less than the thickness of said tubular body at the remaining portions thereof.
Claim 2
Dependent Claim
205 words
A resilient bearing bushing for use between a rotatingly or slidingly operating cylindrical shaft and a cylindrical housing for said shaft, said resilient bearing bushing comprising a generally tubular body having three arcuate side walls and three arcuate vertices, said side walls each having inner surfaces which are arcuate along their entire circumferential extent, each of said inner arcuate surfaces having a central, circumferential portion constituting a major portion of said arcuate inner surface, said central, circumferential portion resiliently pressed against a corresponding circumferential portion of said shaft, said side walls each having outer surfaces which are arcuate along their entire circumferential extent and which are radially spaced from the inner periphery of said cylindrical housing, said vertices having outer surfaces resiliently pressed against the inner periphery of said cylindrical housing and inner surfaces spaced from the circumference of said shaft, said tubular body having three recesses formed on the inner surface of said tubular body in positions corresponding to said vertices, said recesses having a wall thickness smaller than the thickness of the remaining portions of the tubular body such that the thickness of said tubular body at said vertices is less than the thickness of said tubular body at the remaining portions thereof.
Claim 3
Dependent Claim
20 words
A resilient bearing bushing as claimed in claim 1, further including a longitudinal slit formed along one of said vertices.
