F-0335 Equivalent Error of Tooth Surface by Bending and Twisting Deformation of Gear Shafts

Abstract

A generalized method to calculate axis displacements of gear pairs caused by bending and twisting deflections of gear shafts is proposed, and also a calculation method of equivalent tooth surface errors based on the axis displacement is proposed. Through a couple of calculation examples, it is shown that there is a combination of gear dimensions and gear drive structure to minimize the equivalent surface errors.
