This paper presents a method of evaluating the effect of micro-geometric or micro-topographic variation on various gear performance parameters, such as noise excitations, gear contact and root stresses, film thickness, and surface temperature under loaded conditions. Micro geometries that are considered are profile crown, profile slope, lead crown, lead slope, and bias modifications variations. Various combinations of these micro geometries are considered in analytical simulations in which respective gear design metrics are evaluated based on the calculated load distributions. This paper will provide a walk through analysis for a helical gear design in order to describe the procedure.
