Abstract


In this paper, a finite elements model of a gear system composed of external and internal gear is developed. The gearmesh stiffness which is the main excitation source of the system is computed for various cases of the internal gear design. The rim thickness, the shape and the fixing mode are varied. It is shown that this design affects considerably the evolution of the gearmesh stiffness which will certainly affect the dynamic behaviour of the internal gear system.
