The crown wheel resembles a ring-shaped curved rack. The pressure angle decreases continuously from the outer to the inner diameter. Thus, the variable peripheral speed at the crown wheel is compensated against the constant peripheral speed of the pinion. The pointed outer teeth and the steep tooth flanks on the inner diameter limit the usable tooth width. Crown gears achieve similar efficiencies as spur gears. One crown gear can drive several pinions.
