To issue of impact effects in planetary transmission systems with spur gears
 Hortel, Milan ; Škuderová, Alena
The designing of gear systems with split power flow needs to be based on the perfect knowledge of dynamic phenomena in these light weekly and strongly nonlinear parametric systems. One in the notable dangerous effects of internal dynamics of such systems are impact effects due to tooth backlash existence in gear mesh. The contribution deals with simulation analysis of dynamic properties of impact effects in damping dependence for special case of system with split power flow.

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 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.

K vlivu zubové vůle a tlumení v zubové mezeře na dynamiku nelineárních parametrických soustav s kinematickými vazbami
 Hortel, Milan ; Škuderová, Alena
World state of the art of high-parametric light transmission systems with gear wheels of minimum dimensions of aeronautical and automotive industry leads to constructions with direct and split power flow. The gear backlash in spur gears and damping in tooth spaces significantly influences dynamic properties of such high-speed systems with kinematic couplings.
