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.
