An analytical approach towards EHD analysis of connecting-rod bearing

Elastohydrodynamic (EHD) journal bearings in rotating machine parts are subjected to very severe operating conditions, leading to a reduction in the minimal thickness of the lubricating film which can generate premature wear of the contact. In this work, an analytical method of calculating the minim...

Summary:Elastohydrodynamic (EHD) journal bearings in rotating machine parts are subjected to very severe operating conditions, leading to a reduction in the minimal thickness of the lubricating film which can generate premature wear of the contact. In this work, an analytical method of calculating the minimal thickness of the oil film was proposed. It takes into account the effect of the elastic deformations due to both hydrodynamic pressure and inertia. The elastic deformations are calculated analytically and simultaneously. The connecting - rod bearing body defor sub(:) mations was predicted under low and moderate engine regimes. The correction produced by the introduction of the effect of inertia, have shown a clear difference for the global behaviour. The method was applied for analysis of a General Motors connecting - rod bearing engine.Original Abstract: Elastohidrodinaminiai guolio kakliukai besisukanciose masinu dalyse veikiami labai sunkiu, sukelianciu tepalo sluoksnio pleveles suplonejima, darbo salygu gali issaukti prieslaikini kontaktini dilima. Siame darbe pasiulytas analitinis minimalaus tepalo pleveles storio skaiciavimo metodas. Jame ivertintas tampriuju deformaciju poveikis atsirandantis del hidrodinaminio slegio ir inercijos. Tampriosios deformacijos paskaiciuotos analiniu ir skaitiniu metodu. Jungiamosios traukes-guolio deformacijos buvo ivertintos esant vidutinems ir mazoms variklio apkrovoms. Analize atlikta ivertinus inercijos efekto itaka guolio funkcionavimui stipriai skyresi nuo iprastines. Metodas buvo pritaikytas General Motors variklio jungiamosios traukesguolio analizei
