WebbA pair of gears can only mesh correctly if the pitches and the pressure angle are the same. ... WebbIn involute gears, the pressure angle remains constant throughout the engagement of teeth which results in smooth running. The involute system has a standard pressure angle which is either 20° or 14½°, whereas on a cycloidal system, the pressure angle varies from zero at pitch line to a maximum at the tips of the teeth.
