The load distributions along the line of obtained the tooth modifications (tip relief) based action, the elastic deflections and transmission errors of gear pairs are on the deflection results found using the combined obtained by solving the equations of compatibility of displacement approach of 3-D elastic theory and a mapping and equilibrium of forces. This paper discusses the influence of tooth flank corrections (tip function. The tooth proportions that
