Abstract
Abstract Constant velocity joint coupling includes one joint half-formed with a plurality of axially parallel concave race surfaces defining a number of cylindrical spaces therebetween; and another joint half-including a hub having at least three arbors extending radially in stellate form therefrom, and a spherically convex roller-shaped joint member rotatably and axially displaceably mounted on each of the arbors, the joint members being received respectively in the cylindrical spaces, the hub having a free end formed with a spherically convex axial bearing surface having a center of curvature located at the point of intersection of the longitudinal axis of the hub and the axes of the joint members, and the one joint half being formed with a support bearing surface cooperatively engaging the axial bearing surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
Constant velocity joint coupling comprising a pair of joint halves, one of said joint halves being formed with a plurality of axially parallel concave race surfaces defining a number of cylindrical spaces therebetween; and the other of said joint halves including a hub having at least three arbors extending radially in stellate form therefrom, and a spherically convex roller-shaped joint member rotatably and axially displaceably mounted on each of said arbors, said joint members being received respectively in said cylindrical spaces, said hub having a free end formed with a spherically convex axial bearing surface having a center of curvature located at the point of intersection of the longitudinal axis of said hub and the axes of said joint members, and said one joint half being formed with a support bearing surface coOperatively engaging said axial bearing surface.
Claim 2
Dependent Claim
138 words
Constant velocity joint coupling comprising a pair of joint halves, one of said joint halves being formed with a plurality of axially parallel concave race surfaces defining a number of cylindrical spaces therebetween; and the other of said joint halves including a hub having at least three arbors extending radially in stellate form therefrom, and a spherically convex roller-shaped joint member rotatably and axially displaceably mounted on each of said arbors, said joint members being received respectively in said cylindrical spaces, said hub having a free end formed with a spherically convex axial bearing surface having a center of curvature located at the point of intersection of the longitudinal axis of said hub and the axes of said joint members, and said one joint half being formed with a support bearing surface coOperatively engaging said axial bearing surface.
Claim 3
Dependent Claim
12 words
Coupling according to claim 1 wherein said support bearing surface is planar.
Claim 4
Dependent Claim
42 words
Coupling according to claim 1 wherein said support bearing surface is formed on an inner end face of a central cover sealingly secured to a side of the one joint half at which a shaft associated with said joint half is attachable.
Claim 5
Dependent Claim
83 words
Coupling according to claim 1, including an annular spherically concave axial bearing surface formed at the free end of said hub facing said center of curvature and having a radius of curvature equal to the distance from said concave axial bearing surface to said center of curvature, and further including a spherically convex support bearing surface, having substantially the same radius of curvature of said concave axial bearing surface, formed on said one joint half and cooperatively engaging said concave axial bearing surface.
Claim 6
Dependent Claim
52 words
Coupling according to claim 4, including a shaft stub member extending from said hub, said convex and concave axial bearing surfaces being formed on a bearing head secured to said shaft stub member, said bearing head being fittingly received with clearance between said support bearing surfaces formed on said one joint half.
Claim 7
Dependent Claim
58 words
Coupling according to claim 5 wherein said one joint half is formed with a cavity having an opening through which said shaft stub member extends into said cavity, and including a ring secured to a transverse wall of said one joint half and disposed coaxially to said opening, said convex support bearing surface being formed on said ring.
Claim 8
Dependent Claim
17 words
Coupling according to claim 5 wherein said bearing head is threadedly secured to said shaft stub member.
