| Abstract | ||
| This paper investigates the effect of bearing shell elastic deformation on the steady state behavior of misaligned journal bearings. Performance trends of elastic and rigid bearings with different degree of misalignment (Dm) have been compared. Bearing shell elastic deformation, thermal effects, pressure and temperature variation for a bearing working under turbulent lubrication have been taken into consideration. It is found that misaligned bearings working at higher misalignment coefficients have higher load carrying capacity since the oil film thickness approaches to zero in this case. Considering the effect of bearing shell elastic deformation with the effect of oil film temperature causes lower values of bearing load. Some of the results obtained in this paper have been compared with that published by other workers and found to be in a good agreement. | ||
