The new approach for calculation of total mesh stiffness and nonlinear load distribution for helical gears

Abstract

This paper described a new approach for calculation of mesh teeth stiffness and load distribution for helical gears. The mesh teeth pair stiffness is a parameter that varies both during a teeth pair mesh period and along teeth pair contact line, and can be work out only by simultaneously solving both these tasks. The Finite Element Analysis (FEA) is performed to calculate the gear teeth pair’s total deformations and normal load functions in time and along teeth pair contact lines. The specific iteration procedure is used, too. The total mesh stiffness and normal load distribution calculated with this procedure can be used for precise helical gears load capacity calculations and evaluation of nonlinear dynamic model of helical gears motion.
