In this paper based on a gearbox model a suitable simplified model of the gear was built and analysed. The main focus of interest in this study was to determine the basic parameters affecting the gear rattle generation. The problem of meshing gear wheels with spur teeth which can be in mesh on the second line of action with taking into account random deviations of base pitches were taken into consideration. The deterministic model of the gear for idle running was examined by a given form of viscous damping. The type of vibrations was specified for different parameters and their levels as well as the search for the symptoms of chaotic motion for low levels of damping were also within our scope of interest. For the suitable combination of external forces, backlash, varying meshing stiffness as well as low damping, it appears that the contact of the driving flank of the tooth of the pinion and the opposite flank to the driven one of the tooth of the driven gear takes place.
