To some dynamic phenomena in strongly nonlinear parametric systems with split power flow
Hortel, Milan ; Škuderová, Alena
Planetary gear differential systems constitute the basic structureof gearing systems in aircraft and automobile industry. Theinternal dynamic forces can have important signification foroperating safety and reliability in kind of such high powersystems with minimum dimensions. The important function here havee.g. the impact effects in gear mesh, caused by greater dynamicthan static and elastic deformations of gear tooth in mesh and dampinginfluence in all phases of gear mesh.

To modelling of phenomenons of internal dynamics of systems with strong non-analytical nonlinearities
Škuderová, Alena
The creation of model of two spur gears with elastic supports so, in order that to waht mostly approximate real fact, was the aim of this work. This model considers the influence of motion in bearings not only at direction of line of mesh, but and at al direction, the damping and periodically variable stiffness into the gear mesh, frictional forces, possibly eccentricity of gears or manufacturing inaccuracy of teeth profile and influences of impacts, caused by existence of backlash.

To issue of tooth backlash in dynamics of aeronautical and mobil gear systems with split power flow
Hortel, Milan ; Škuderová, Alena
In framework of internal dynamics of highparametric gear systems with split power flow the impact effects caused by greater dynamic than static-elastic deformations in the gear mesh have important role. They cause not only the additional dynamic load of gear pairs, but also violation of existence conditions of continuous carrier layer of lubrication. This make possible creation of dry friction in gear mesh with eventuality of self-excited vibrations rise and consequently decrease of gearing service life.
