Practical Method for Analyzing the Three Dimensional Contact Problems of Gears

This paper describes the analytical method for calculating contact stresses in spur and helical gears using the boundary element method. Since in many old studies the effect of load distribution is not analyticaly taken into account, attention must be given to some essential and fundamental method for computing the influence of contact stresses into the analysis. The main advantage of applying the boundary element method to the contact problem of gears is to give the proper expressions for load distribution and contact width along the line of contact.
