In this paper, one dynamic model of a real gear set has been presented. In this case, the simplified model contains two discreet masses with elastic and damped connections. The basic principles of mechanics, with the initial and boundary conditions taken into account, were applied in establishing a system of differential equations describing the physicality of motion. Such system of differential equations represents a mathematical model at dynamical behaviour of gear transmission. The established system of differential equations has been solved in a numerical way. The paper presents the solution of the main form of oscillating and stress condition, using the finite element  method.

Key words: gear, gear set, dynamic behaviour, dynamic load, own oscillations, mathematical modelling, numerical analysis, system of differential equations, finite element method.
