Zusammenfassung:In this paper, the authors analyze the elliptical gears from the kinematic, dynamic, and of the inlaid torsional vibrations points of view. They study the uni-lobe and bi-lobe elliptical gears. To be out to determine the mechanical parameters for the dynamical calculation, one obtains, using AutoCAD, the solids that materialize the gears, by an algorithm, similar to the practical procedure to obtain the gears using a basic rack-type cutter. Thus one accurately obtains the masses and moments of inertia of the gears. To obtain the equation of motion, they used a dynamical model of a bar in rotational motion that replaces the mechanism consisting in driving motor, elastic linkage, fly wheel, and the gear of two elliptical gears. The integration of the equation of motion is numerically realized using the fourth order Runge-Kutta method, and a calculation program written in Turbo Pascal. They present the obtained frequency diagrams. Finally, the conclusions end this.
