ABSTRACT:
A traction roller transmission having a number of traction rollers disposed in an annular space formed between a sun roller structure rotatable with one shaft and a traction ring structure surrounding the sun roller. The traction rollers are rotatably supported and the traction rollers or the traction ring structures are mounted for movement with another shaft. At least one of the traction surfaces of the sun roller and the traction ring structures is formed by a sleeve and radially slotted spring washers are disposed behind the sleeve. Cam structures are arranged axially adjacent the spring washers such that a torque transmitted through the transmission forces the spring rings onto said sleeve and said sleeve toward said traction rollers for firm engagement of the traction rollers with the traction ring and the sun roller structures.
