In reviewing various industrial software modules used by bearing suppliers and engine companies, we have found a fair level of agreement between them in the final results. We also discovered, however, some unresolved areas which merit further discussion. This paper will focus primarily on those unresolved areas:
the treatment of partial groove bearings
calculation of oil flow quantity and its associated temperature rise and friction
selection of the bearing clearance
the optimal location of the journal oil hole in the main bearing
prediction of the fatigue endurance life
minimum oil thickness allowable
the prediction of the wear pattern.
Our approach in these areas will be described and then compared with that taken in other industrial softwares.
