This paper presents a scheme of calculating the dynamic behavior of dual-path gearbox with non-symmetric position of two pinions in regard to gear. The influence of mesh phase and time-varying mesh stiffness of the two spur pinions and one gear was presented. General model with mathematical equations for dual-path gearbox were described. According to Lagrange theorem, the dynamic differential equations were obtained. Based on these equations results of torsional oscillations, internal dynamic meshing forces were calculated as well as dynamic coefficient Kv. Conclusions were made.

In this paper, the method of determination of dynamic forces generated in two-stage dualpath gearbox is presented. These forces were evaluated based upon the complex physical 6-DoF-model of the cylindrical two-stage dual-path gearbox. Value of the dynamical factor adequate for the determined loading was calculated.
