On the Bending Stress of Spur Gear : (3rd Report, On the Calculation Results of Bending Stress of Gear Tooth)

Abstract

For the purpose of calculating the bending strength of the gear tooth in general use, the authors studied theoretically the position of the weakest section of gear tooth and the point of the worst loading, and consequently definited the calculating method of nominal stress. Then by using the calculating equation of bending stress reduced above, authors calculated bending stress and stress concentration factor of gear teeth of various shapes in general use at present, and studied these relations.
