Abstract
A gear pair and nutation reducer are provided. The gear pair is formed by a pin gear and a non-instantaneous-pole enveloping gear in meshing engagement with each other, the effective tooth surface of the pin gear being constructed of an elliptical cone segment that is outwardly convex, and the distance between the highest and lowest points on the elliptical cone segment in the same cross-section gradually decreases inwardly along the generatrix of the reference cone of the pin gear.
