When one drive pinion gear tooth contacts only certain ring gear teeth, the gear set is a non hunting gear set. A typical
non hunting gear set may have ten drive pinion teeth and thirty ring gear teeth. The rear-axle ratio for this combination
would be 3.00:1. For every revolution of the ring gear, each drive pinion tooth would contact the same three teeth
of the ring gear. The drive pinion gear teeth do not hunt out all ring gear teeth.
