Abstract
This disclosure relates to a gear pair for power transmission in a speed increaser or reducer and its tooth profile forming method. The tooth profiles of driving gear and driven gear are separately designed from reference points. The upper tooth profiles are composed of conjugate curves, while the lower tooth profiles are composed of smooth convex analytic curves. The reference point of the driven gear is located adjacent the middle of the working depth. The reference point on the tooth profile of the driving gear and the reference point on the driven gear tooth flank are a pair of conjugate points.
