ABSTRACT:
In a traction roller transmission in which traction rollers are rotatably supported in the annular space between concentric sun roller and traction ring structures, at least one of said sun roller and traction ring structures has a tapered support surface with a tightly wound coil spring having a tapered surface supported on said tapered support surface and an opposite cylindrical surface in engagement with said traction rollers and means are associated with said transmission for forcing the coil spring onto said tapered surface so as to cause firm engagement of the traction rollers with the sun roller and traction ring structures.
