| Abstract | ||
| An investigation to the turbulent lubrication performance of journal bearing considering journal misalignment and bearing elastic deformation has been established and validated through this work. Oil film pressure, side leakage flow rate, friction coefficient and misalignment moments at variant journal misalignment and bearing elastic deformation are calculated based on the modified Reynolds equation to include the effect of turbulent flow of oil due to high speeds of journal .Suitable models for journal misalignment and bearing elastic deformation have been used and included to the oil film thickness. Some of the results obtaind through this work have been compared with that obtained by the other workers and found to be in agood agreemnt. It has been shown that the combined effect of the bearing shell elastic deformation and the journal misalignment has a considerable effect on the bearing parametres and can not be neglected. | ||
