Abstract

In order to obtain the desired hardness and strength properties of gear teeth, gears designed for relatively large load-carrying capabilities are heat treated after the teeth have been cut. If maximum precision is not required, no finishing operation is carried out after heat treatment. During the heating and cooling cycles of the heat-treatment operation, both volumetric and shape distortions can occur that are caused by thermal gradients within the part, changes in metallurgical structure, material inhomogeneities, etc. The resulting dimensional changes are of sufficient magnitude to seriously affect the performance of gears.
