Kraus, C E

This patent describes a traction roller transmission. It comprises a housing, two planetary type transmission structures arranged in tandem in the housing, each including a sun roller, a traction ring having a traction surface spaced from the sun roller and planetary traction rollers disposed in the space between, and in engagement with, the sun roller and traction ring, and a planetary traction roller support member rotatably supporting the traction rollers, the planetary traction roller support member of one of the planetary type transmission structures having the sun roller of the other planetary type transmission structure associated for rotation therewith, an input shaft connected to or forming the sun roller of the one planetary type transmission structure, and an output shaft associated with the planetary traction roller support structure of the other planetary type transmission structure, means for forcing the traction rings toward one another with a force which depends on a torque transmitted through the transmission.
