Abstract
Abstract The rocker arm bearing assembly has a rocker arm which oscillates on a bearing support member and an associated pair of bearings. The bearings are self-contained units with an outer race, an inner race, and multiple rollers positioned between the two races. Full-complement radial bearings are preferably utilized. The bearings are supported on the bearing support member to form an integral unit which can be dropped into the rocker arm. This allows for speedy assembly of the rocker arm with the bearing and support member unit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
A rocker arm bearing assembly comprising: an immovable support stud; a bearing support member immovably affixed to said stud, said member being configured so as to support and retain two coaxial bearings; a rocker arm having a generally cup-shaped configuration, said arm having a lower portion with an arcuate shape, said arm also having at least two side walls upwardly-extending from said lower portion, and said lower portion having an elongate aperture formed therethrough so as to accommodate said stud and said support member; and means for supporting said support member within said rocker arm so as to provide for oscillating movement of said rocker arm on said two bearings, wherein said means comprises two horizontally-extending arms integrally attached to said support member, each of said arms having an end surface; and a convex protuberance projecting outwardly from each of said end surfaces of said support member arms.
Claim 2
Dependent Claim
148 words
A rocker arm bearing assembly comprising: an immovable support stud; a bearing support member immovably affixed to said stud, said member being configured so as to support and retain two coaxial bearings; a rocker arm having a generally cup-shaped configuration, said arm having a lower portion with an arcuate shape, said arm also having at least two side walls upwardly-extending from said lower portion, and said lower portion having an elongate aperture formed therethrough so as to accommodate said stud and said support member; and means for supporting said support member within said rocker arm so as to provide for oscillating movement of said rocker arm on said two bearings, wherein said means comprises two horizontally-extending arms integrally attached to said support member, each of said arms having an end surface; and a convex protuberance projecting outwardly from each of said end surfaces of said support member arms.
Claim 3
Dependent Claim
191 words
A rocker arm bearing assembly comprising: an immovable support stud; a bearing support member immovably affixed to said stud, said member being configured so as to support and retain two coaxial bearings; a rocker arm having a generally cup-shaped configuration, said arm having a lower portion with an arcuate shape, said arm also having at least two side walls upwardly-extending from said lower portion, and said lower portion having an elongate aperture formed therethrough so as to accommodate said stud and said support member; and means for supporting said bearing support member within said rocker arm so as to provide for oscillating movement of said rocker arm on said two bearings, wherein said means comprises two horizontally-extending arms integrally attached to said support member, each of said arms having an end surface; and an indent formed in each of said two rocker arm side walls so as to form convex surfaces inside each of said side walls, said two convex surfaces being positioned so as to mate with said support member arm end surfaces and thereby allow said rocker arm to oscillate on said two convex surfaces and said two bearings.
Claim 4
Dependent Claim
191 words
A rocker arm bearing assembly comprising: an immovable support stud; a bearing support member immovably affixed to said stud, said member being configured so as to support and retain two coaxial bearings; a rocker arm having a generally cup-shaped configuration, said arm having a lower portion with an arcuate shape, said arm also having at least two side walls upwardly-extending from said lower portion, and said lower portion having an elongate aperture formed therethrough so as to accommodate said stud and said support member; and means for supporting said bearing support member within said rocker arm so as to provide for oscillating movement of said rocker arm on said two bearings, wherein said means comprises two horizontally-extending arms integrally attached to said support member, each of said arms having an end surface; and an indent formed in each of said two rocker arm side walls so as to form convex surfaces inside each of said side walls, said two convex surfaces being positioned so as to mate with said support member arm end surfaces and thereby allow said rocker arm to oscillate on said two convex surfaces and said two bearings.
Claim 5
Dependent Claim
77 words
A rocker arm bearing assembly according to claim 1, wherein said means for supporting said bearing support member within said rocker arm further comprises an indent formed in each of said two rocker arm side walls so as to form convex surfaces inside each of said side walls, said two convex areas being positioned so as to mate with said protuberances and thereby allow said rocker arm to oscillate on said two protuberances and said two bearings.
