3a). For a bevel gear all the calculations are based on the number of teeth in the pinion and the gear. The shaft angle, reference cone angles are calculated based on the number of tooths as given below,
Let  and  be pinion and gear tooth numbers, shaft angle, and reference cone angle and , then:
Generally, a shaft angle is 90 degrees for most cases.
