The design method of double-side meshing and dual-phase driving timing silent chain system is presented. A dynamic analysis model is built, and the fluctuation of the tension sprocket, and the vibration of the system, and the rotation speed stability of exhaust camshaft sprocket, and the transmission error of the intake camshaft sprocket and exhaust camshaft sprocket, and the contact force between the link plate and other components are analysed. Furthermore, dynamic characteristics of the system are contrasted with a single-phase timing silent chain system. Analysis results show that the double-side meshing and dual-phase driving timing silent chain system has a distinct advantage in reducing vibration and enhancing driving stability. The system designed in this paper can meet the requirements of engine timing system, which further verifies the scientific validity and effectiveness of the design method of the double-side meshing and dual-phase driving timing silent chain system proposed in this paperZ namenom izboljšanja zmogljivosti sistema tihe krmilne verige sta bila zasnovana nova vrsta dvostranskega ubiranja in sistem dvofaznega pogona tihe krmilne verige. Predlagana je metoda za snovanje takšnih sistemov. V raziskavi dinamičnih lastnosti sistema dvostranskega ubiranja in dvofaznega pogona tihe krmilne verige je bila preverjena racionalnost in znanstvenost metode snovanja omenjenega sistema dvostranskega ubiranja in dvofaznega pogona tihe krmilne verige. Predstavljena je metoda snovanja sistema dvostranskega ubiranja in dvofaznega pogona tihe krmilne verige. Rezultat snovanja je geometrijski model oblike členov tihe verige in verižnikov, izračunan pa je tudi položaj skupin napenjalnih in prostih verižnikov ter dolžina tihe verige. Na ta način je vzpostavljen sistem dvostranskega ubiranja in dvofaznega pogona tihe krmilne verige. S primerjalno analizo sistema dvostranskega ubiranja in dvofaznega pogona tihe krmilne verige ter enofaznega pogona verige so bile preučene dinamične lastnosti sistema (vključno s stopnjo fluktuacij napenjalnega verižnika, vibracijami členov, vrtilno hitrostjo verižnika na izpušni odmični gredi, napakami prenosa in kontaktno silo)TEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
