Stresses in Helical Gear Teeth

抄録

In the present paper, the author has derived a method for calculating the stresses in herical gear teeth by applying the solution for the moments induced in a cantilever plate with infinite length subjected to a concentrated load. That is, the helical gear tooth was regarded as a cantilever plate with finite length and the distributed load on the contact line of tooth was considered as a group of concentrated loads per unit length. And then, from the further investigation for this calculating method, a simplified formula for the calculation of stresses in helical gear teeth has been developed. The stresses in gear teeth calculated by these methods are shown to be in good agreement with those measured by wire resistance strain gauges cemented in the actual gear teeth.
