Abstract
The synthesis of gear transmissions with arbitrary n-pair tooth contact is considered (n is any integer greater than two). Multipair engagement is the result of height and profile modification of the teeth, by adjustment and shift of the initial contour. Formulas for force and strength analysis of multipair transmissions are presented. Examples outline the synthesis of transmissions with engagement at three, four, or more pairs, in any working range of the number of teeth. The benefits of multipair engagement are illustrated by sample calculations of a tooth pair in single-pair and multipair engagement.
