Abstract


Internal dynamic forces and displacements along the anticipated degreeses of freedom in the planetary gear trains are consequence of coupled teeth elastic deformations, vibrations of train parts and gear geometries changes due to tooth wearing and cutting errors.

In this paper are considered influence of time-varying mesh stiffnesses to practicable displacements and forces in tooth contacts. This function was useful as nonlinear coefficients gear mesh stiffness in system of diferential equations for equivalent gear train model in determination of nature displacements and internal dynamic forces. Numeric results of dynamic analysis of diferential equations who dynamic behaviour was described are time-varying functions of displacements points of the system and dynamic forces in tooth meshes of the sun-planet and ring-planet.
