Abstract
Abstract This invention relates to a transmission coupling with a spherical roller. The spherical roller is pivotally mounted on a spindle with or without the interposition of pins for rolling movement in two opposed grooves formed in a jaw. The roller includes two half rollers symmetrical about a plane perpendicular to the spindle and including a great circle of the sphere formed by the roller. A resilient member which may be a Belleville washer or a ring of elastomeric material is interposed between the planar and parallel surfaces of the half rollers facing each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
A transmission coupling, comprising a spherically shaped roller mounted for rotation on a spindle, two opposed part cylindrical elongated grooves for receiving the roller for rolling movement therein, said roller including two half rollers arranged substantially symmetrical about a plane perpendicular to the spindle containing a great circle of the sphere and formed by the roller, said half rollers having spaced opposed surfaces and a resilient member interposed between said opposed surfaces of said half rollers and urging said half rollers apart.
Claim 2
Dependent Claim
82 words
A transmission coupling, comprising a spherically shaped roller mounted for rotation on a spindle, two opposed part cylindrical elongated grooves for receiving the roller for rolling movement therein, said roller including two half rollers arranged substantially symmetrical about a plane perpendicular to the spindle containing a great circle of the sphere and formed by the roller, said half rollers having spaced opposed surfaces and a resilient member interposed between said opposed surfaces of said half rollers and urging said half rollers apart.
Claim 3
Dependent Claim
58 words
A transmission coupling according to claim 1, wherein said opposed surfaces of the half rollers are planar and parallel to each other, and wherein the resilient member is of the type which becomes substantially nondeformable upon the apPlication of a predetermined compression force, thereby assuring a solid connection between the two half rollers in their torque transmitting position.
Claim 4
Dependent Claim
17 words
A transmission coupling according to claim 2, wherein the resilient member comprises at least one Belleville washer.
Claim 5
Dependent Claim
17 words
A transmission coupling according to claim 2, wherein the resilient member comprises at least one corrugated washer.
Claim 6
Dependent Claim
55 words
A transmission coupling according to claim 1, wherein the resilient member is received in two circular grooves formed in said opposed surfaces of the two half rollers, said resilient member being fully seatable in said circular grooves and allowing said half rollers to come into direct contact with each other in their torque transmitting position.
Claim 7
Dependent Claim
17 words
A transmission coupling according to claim 5, wherein the resilient member comprises a ring of elastomeric material.
