Fillet Stress Related to Non-Uniformly Loaded Gear Tooth Geometry

The influence of non-uniform load distribution along spur gear tooth facewidth, upon the fillet stresses, has been investigated by means of the Finite Element Method p-version. There have been taken into consideration different load distribution cases corresponding to the contact without errors, the possible alignment error in fitting the gear, and the effect of gear crowning. The results of the investigation performed by 3D numerical approach, have enabled the determination of spur tooth stress maximum value and its position both, along the tooth fillet and facewidth, for complex combined influence of gear geometrical parameters and non-uniform load distribution. The obtained maximum equivalent von Mises stress and axial stress that arises in the direction of gear axis, were compared for different load distribution acting along the tooth facewidth.
