Influence Functions of Bending Moment of Bevel Gear and Approximate Equations.

Abstract

Before the calculation of the load distribution on the line of contact and the tooth root stress of a bevel gear under tooth end bearing, the tooth root stress due to the concentrated load was calculated by means of the three-dimensional finite-element method (FEM). With the results by FEM, the approximate equations for the influence functions for bending moment of bevel gear tooth were derived. Furthermore, the effects of the number of teeth and the gear ratio on the characteristics of bending moment were clarified.
