Discussion: “Evaluation of Dynamic Factors for Spur and Helical Gears” (Seireg, A., and Houser, D. R., 1970, ASME J. Eng. Ind., 92, pp. 504–514)

Abstract

fcj), = spur gear tooth stiffness along line of action, lb/in. F = face width, in. h -effective tooth height, in. I = effective tooth thickness, in. E ~ modulus of elasticity, psi k' = stiffness per in. of face (approximately = 2 X 10 6 lb/in. /in. for test gear)
