Abstract: The generating and kinematical analysis of the gear pair profiles in contact with internal trochoidal gearing from tribological aspect is considered in this paper. By the working elements of the rotational machines is used trochoidal gearing, as for an example, at gerotor pumps and hydro motors. In this paper are analysed the geometrical and kinematical relations of the trochoidal gearing the specific sliding in the meshing profiles process and the numerical examples of the influence of the different construction parameters on the kinematical characteristics of the trochoidal gearing in contact. By them are taken the different coordinate systems and with the application of coordinates transformation is possibly to realise the most simple equations. The moving of the contact point of two profiles is considered in the kinematical analysis as complex because during the contact period the profiles are rolling and sliding in the same time in relation ones to other. Using geometrical and kinematical models of the trochoidal gearing, we provide detailed analysis of specific sliding at the contact points of the profiles, as well as the relations for its determination. To the analysis of the wear phenomenon except of the sliding velocity is important also the size of the summary rolling velocity. Based on the graphical interpretation of kinematical parameters profiles in contact of trochoidal gear pair can be concluded about the influence of geometrical parameters on the size of sliding and also on the wear intensity of the teeth profile.
