Abstract

The bending stress of gearing defined by calculation and the actual values of teeth stress may be vary significantly. The stress calculated in a standard way according to available formulas is approximate because some impacts cannot be determined with sufficient accuracy. Recently, at ever faster evolving computer technology, the available literature, we can meet with modern numerical methods, such as finite element method (FEM). The article is devoted to problems determining of the stress in a dangerous section of tooth foot using FEM. The problem is solved for elliptical, eccentric gear with asymmetrical profile of tooth.
