Micropitting is an area of gear failure that influences gear noise and transmission error. This paper outlines an approach to analysing micropitting by looking at the critical factors for a given gear design. A practical procedure, which incorporates a three-dimensional spring model, was used to predict the micropitting wear rate and the position that wear would take place on test gear pairs. Case studies have been included that directly compare the predicted levels of micropitting with those actually measured. A simplified formulation suitable for manual calculations are also discussed.
