ABSTRACT:
Basic pitch curves of a ball nut rack and sector gear of a recirculating ball type steering gear have basic pitch curves which provide a gear ratio which is a desired function of the degree of turn of the steering wheel. The teeth of the rack are formed on a stepped reference line which is different from its basic pitch curve.
