Stresses in Helical Gear Teeth
Transactions of the Japan Society of Mechanical Engineers, 1966 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 ...
