Function-oriented Tolerancing of Tooth Flank Modifications of Beveloid Gears
Abstract Today, designing the microgeometry of gears is often based on experience. Usually, objective values (Hertzian pressure, …) from a tooth contact analysis are evaluated. In many cases the manufacturing tolerances are not fully considered in...
