ABSTRACT:
A gear assembly has a driving pinion, a rack and an intermediate gear coupling the pinion and rack. The teeth of the pinion, gear and rack are of the same pitch, the teeth of the intermediate gear being separated into one sector of teeth which engage the pinion and another sector of teeth which engage the rack. The axis of the intermediate gear is off-center, the radii of curvature of the pitched circles of the two sectors of the intermediate gear are different, and the teeth of the two different sectors of the intermediate gear are not integrally related to the circumference of the respective pitched circles.
