ABSTRACT:
A planetary type traction roller transmission includes first and second sun roller structures and traction rings with first and second motion transmitting traction rollers disposed in the annular spaces between, respectively, the first and second sun roller structures and traction rings. The axis of the sun roller structures is spaced from the axis of the traction ring so that an annular space of varying width is formed between the sun roller structures and the respective traction rings and the first and second traction rollers are supported in the respective annular spaces by support means permitting movement of one, either the first or second traction rollers, into a narrowing area of respective annular space while the others are moved into a widening area of their respective annular space for engagement of the one set of traction rollers with, and disengagement of the other set of traction rollers from, the respective traction rings and sun roller structures.
