ABSTRACT:
A traction roller transmission having a number of planetary type rollers disposed in an annular spaced formed between a sun roller rotatable with one shaft and a traction ring surrounding the sun roller. The traction ring, the planetary rollers and the sun roller all have annular projections and recesses with inclined hard metallic lubricated side surfaces by which the planetary rollers are in engagement with the sun roller and the traction ring for the transmission of motion therebetween. Preferably, means are provided for forcing planetary rollers into engagement with the traction ring and the sun roller with forces which depend on the torque transmitted through the transmission.
