Finite element analysis of cylindrical gears. (English) Zbl 0913.73067
Summary: We propose a method, namely the normal stiffness matrix along contact line method, for analysing gears. Three-dimensional finite element solid models have been established. Cylindrical gears – spur and helical, external and internal, hobbling and slotting, different parameters and materials – can be analysed using these models. Result such as load distribution along the contact lines, deformations and stiffness at any contact position, and contact stresses are given which show that gear tooth deformations coincides with tested ones using the dynamic speckle photography method.
