Miter bevel gears are a special class of bevel gear, where the gear shafts intersect at 90° (each of the two gears has a 45° pitch angle) and both gears have the same number of teeth i.e., the gear ratio is 1:1. Fig. 1.10 depicts a typical miter gear arrangement. Miter gears may be of straight or spiral tooth profile.
