Abstract A transmission has an input shaft, a fixed ring, a rotatably mounted driven ring, one ring being smaller than the other by a given amount, at least one roller having longitudinally displaced portions, one portion being smaller than the other by the same amount as the rings, and means enabling the input shaft to revolve the at least one roller within the rings with the smaller diameter portion rolling in the smaller ring and the larger diameter portion rolling with the larger ring to drive the rotatably mounted ring as an output. Modifications of the transmission provide conical rollers and corresponding conical rings, rollers and rings having surfaces which provide point contact therebetween, and a plurality of longitudinally displaced portions of rollers with a plurality of driven output rings.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
170 words
A roller transmission comprising, in combination, an input shaft, a fixed ring disposed about said shaft, a rotatably mounted ring disposed about said shaft, said rings having larger and smaller cylindrical inner surfaces, rollers each having larger and smaller cylindrical portions, said larger and smaller cylindrical portions of said rollers differing in diameter the same amount as the larger and smaller cylindrical inner surfaces of said rings, and a spider mounted on said shaft, said spider having pairs of arms containing radial slots receiving said axles, each pair of said arms mounting one of said rollers therebetween, said spider revolving said rollers with said shaft so that on rotation of said shaft centrifugal force urges said rollers outward moving said axles in said slots, said larger cylindrical portion of each roller rolling against said larger cylindrical inner surface of a ring and said smaller cylindrical portion of each roller rolling against said smaller cylindrical inner surface of a ring driving said rotatably mounted ring as an output of said transmission.
