For power transmission gears, the tooth form most commonly used today is the involute profile. Involute gears can be manufactured easily, and the gearing has a feature that enables smooth meshing despite the misalignment of center distance to some degree.. 3.1 Module Sizes and Standards. Fig. 3.1 shows the tooth profile of a gear rack, which is the standard involute gear profile.
