Abstract

This paper presents a model of load sharing for high contact ratio internal spur gears, which takes into account the changing rigidity of the pair of teeth along the path of contact. It has been obtained from the minimum elastic potential energy criterion, resulting in a non-uniform load distribution among several tooth-pairs in simultaneous contact. This model has been used for the calculation of the determinant load conditions for pitting calculations, providing the theoretical values of the pitting nominal stresses. As no proposals of load sharing for this kind of internal spur gear transmissions can be found in literature, the proposed model can be used for strength calculations which may be suitable for standardization purposes.
