ABSTRACT:
A steplessly settable gear box provided with a slidable head coupled to an output shaft is disclosed. The slidable head is slidably mounted on a first spur gear coupled to an input shaft and in mesh with an internally toothed fixed annular gear. A second spur gear is in mesh with an internally toothed angularly settable annular gear and the head is so coupled to the second spur gear as to be slidably deplaceable relative to the axis of rotation of the first spur gear in dependence on the angular setting of the last mentioned annular gear.
