To a solution of the resulting movements in the bearings center of the planet gear system with four satellites and their stopped carrier
 Hortel, Milan ; Škuderová, Alena
The presented research report deals with examples of the numerical solution of the influence of some parameters on the internal dynamics of a pseudoplanetary transmission system with four single spur toothed satellites and a stopped carrier of satellites of the Wikov PP type, mainly focusing on the solution of the resulting movements in the bearings of the centers of the satellites. The analysis of the dynamic phenomena in the quasi-state is performed for two selected rotations of the central wheel for one period of the resulting stiffness functions in the gear meshes and the assumed error functions in the gear meshes. Attention is paid to the trajectories of the resulting motion of the center of the satellite positioning in the branch, and to the horizontal (tangential) and vertical (radial) resulting movement of the center of the satellite position, and to the relative movement in meshes of all wheel gears.

The refined model of dynamics of planetary gearbox
 Hortel, Milan ; Škuderová, Alena
The study continues the research report Z 1521/14, which describes the first version of the simulation model of system 42 weakly and strongly nonlinear parametric differential equations, solving motions in individual gear meshes, their bearing including moving the carrier satellites in Matlab / Simulink. The study complements and refines the simulation model of the transmission system by the physical description and modelling of time-varying values and geometric parameters occuring in the motion equations of mathematical and physical model of the planetary differential gear system with three double satellites with straight teeth.
