Load Distribution Model for Involute Internal Gear Sets

This paper presents a new model of load distribution for involute, internal gear drives, which takes into account the changing rigidity of the pair of teeth along the path of contact. The model has been obtained from the minimum elastic potential criterion, resulting in a non-uniform load distribution along the line of contact (for helical gears), as well as among several pairs in simultaneous contact. A study of the nominal contact stress, including the calculation of the determinant load conditions, is also presented.Copyright © 2007 by ASME
