Abstract:

A simple and convenient correction formula is presented in this paper by using calculated value and permissible value of contact stress and flexural stress obtained through the corrected calculation of strength under initial definite geometric parameters of the gear. The complicated and long process of approximation calculation of many times of combinations of geometric parameters and corresponding calculation can be avoided and an accurate enough result can be obtained by using this formula. The formula may be regarded as the important complementation for ISO calculating standard of gear strength.
