ROLLING CONTACT FATIGUE FAILURE OF BEARING STEELS, WHEEL STEELS AND CARBURIZED GEAR STEELS

An optimum heat treatment was developed for load-bearing steels. Friction quenching was used for studying the effect of heat damage of wheel treads on rolling contact fatigue strength. It was shown that no significant change in fatigue strength resulted in the friction quenched specimen. The effective depth of the case of carburized gear steels on rolling contact fatigue strength was also investigated; fatigue strength was raised significantly when case depth exceeded a certain minimum value.
