Abstract

Textbooks such as Norton[l], Juvinall[2], and Shigley[3]and design criteria such as The American Gear Manufacturers' Association (AGMA)[4][5][6] present detailed methodology for determining maximum bending or contact stresses in gears and allowable stresses for the gears. The methods are based upon type of gear (spur, helical, etc.), loading conditions, quality conditions, and so on. Such references do not provide detailed information for determination of stress distribution or deformations. This is particularly true where fail-safe considerations are required in the design and analysis. The finite element method (FEM) has been used to evaluate stresses and deflections in gears. [7] [8] [9] Such modeling can require large models, models so large they exceed the capacity of the system or p
