ABSTRACT:
A ring roller is mounted on an input shaft by a left-hand thread so that when the shaft is rotated in the clockwise direction the sun roller tends to unscrew along the shaft. The sun roller thus drives planet rollers axially along the shafts on which they are rotatably supported into a ring roller which is mounted on an output shaft by a left-hand thread so that it tends, upon being driven in a counter-clockwise direction by the planet rollers, to screw onto the output shaft. The axial movement of the sun roller ceases upon a suitable preloading between the sun, planet and ring rollers' being established.
