Hakan ADATEPE [1]


In this study, the performance of the connecting rod bearing of the one cylinder 4-stroke diesel Ricardo Hydra Engine was investigated at different oil supply pressure (3 bar, 5 bar, 7 bar) by examining the performance of the selected connecting rod bearing as an example; radial journal bearing users and bearing designers. Width the change of the oil supply pressure  at the dynamically loaded connecting rod bearing; how the minimum bearing clearance, the maximum oil film pressure, the friction torque, the shaft orbit in connecting rod bearing and the hydrodynamic power losses that occur in the journal bearing have been theoretically investigated. Using the Ricardo ORBIT V1.2 software analysis were performed using the Finite Volume Method which provides a fast and accurate solution commonly used in the literature. At the different connecting rod bearing width; how it affected the performance of the journal bearing under dynamic load was carefully examined. From the results of the research; increased oil supply pressure; It has been determined that the bearing clearance, the maximum oil film pressure is increased, the friction torque and hydrodynamic power losses increase. The orbit drawn by the shaft orbit in connecting rod bearing is stable. The results of this research showed that the different oil supply pressure plays an important role in minimum bearing clearance, the maximum oil film pressure, the friction torque, the shaft orbit in connecting rod bearing and the hydrodynamic power losses under the dynamic load.

Bu çalışmada, tek silindirli 4 zamanlı dizel Ricardo Hydra motorunun biyel kolu yatağının performansı farklı yağ besleme basıncında (3 bar, 5 bar, 7 bar) incelenmiştir. Dinamik olarak yüklenen biyel kolu yatağındaki yağ besleme basıncı değişiminin; minimum yatak boşluğuna, maksimum yağ filmi basıncına, sürtünme torkuna, mil merkezinin çizdiği yörüngeye ve yatak yuvasında meydana gelen hidrodinamik güç kayıplarına nasıl tesir ettiği teorik olarak incelenmiştir. Ricardo ORBIT V1.2 yazılımı kullanılarak, literatürde yaygın olarak kullanılan hızlı ve doğru bir çözüm sunan Sonlu Hacim Yöntemi ile analizler gerçekleştirilmiştir. Farklı yağ besleme basınçlarında; biyel kolu yatağının dinamik yük altındaki performansını nasıl etkilediği dikkatlice incelenmiştir. Araştırma sonuçlarından; artan yağ besleme basıncı; Yatak boşluğunun, maksimum yağ filmi basıncının arttırıldığı, sürtünme momentinin ve hidrodinamik güç kayıplarının arttığı belirlenmiştir. Mil merkezinin çizdiği yörüngesinde hemen hemen sabit olduğu görülmüştür. Bu araştırmanın sonuçlarırnda, farklı yağ besleme basıncılarının yatağın minimum yatak boşluğuna, maksimum yağ filmi basıncına, sürtünme torkuna, biyel kolu yatağındaki mil merkezi yörüngesine ve dinamik yük altındaki hidrodinamik güç kayıplarına tesir ettiğini göstermiştir
