This paper presents a study on the bending fatigue strength and the effects of addendum modification on bending fatigue strength of spur gears with a higher pressure angle made of normalized steel, cast iron and cast steel. The analysis is made regarding the effects of addendum modification on the true stresses at the root fillet in connection with the worst loading point and also on the bending fatigue strength of gear teeth. Bending fatigue strength of normalized steel, cast iron and cast steel gears can be improved by adopting a higher pressure angle and selecting a proper amount of addendum modification. Addendum modification factor B_x for bending strength is derived from the analytical and experimental results, and the bending fatigue strength of profile shifted gears can be estimated with fairly high accuracy, by introducing this factor into the strength design of gears.
