Abstract

The mechanical behaviour of the chain drive transmissions is influenced of the contacts between elements being in relative motions, as: sprockets and links, links and pins and links and tensioning guides. These contacts have a complex behaviour and due to that it is required to be analysed separately, in order to find out their influences on the dynamical behaviour and on the tribological properties of the entire transmission. The article presents the analysis of the influence in the case of silent chain link geometry on the link/chain guide contact. It is studied the variation of the local normal maximum pressures and the variation of the contact area’s width with the main radius of the chain link and with the normal applied force. The analysis is based on the finite element modelling. Finally there are given conclusions regarding the practical applications of the obtained results.
