Abstract
A rack and pinion gearing comprising a helical rack and a spiral pinion. The rack has a structure defined by a radius, a distance from the axis to tooth crest, a helix angle, and a pressure angle determined from the viewpoint of applied kinematics so as to produce a balancing moment of rotation. The structure keeps the rack free from inclination and rocking about the axis which would otherwise result in a biting effect.
