GEAR SYSTEM

摘要

In a conventional internal gear pair system such as a planetary gear system with a small gear ratio of the internal gear to the driving pinion, common problems include tip interference and limited contact between the teeth of the gears. An internal gear pair system which avoids these problems includes a pinion meshing with an internal gear, the pinion having as few as one tooth less than the internal gear, the only contact between the pinion and the internal gear being on at least one side of a line extending diametrically through the centers of the pinion and the internal gear, and the teeth of the pinion being conjugate to the internal gear teeth.
