Abstract : The report is a survey of numerous published theoretical and experimental investigations in elastohydrodynamic lubrication with the intent of establishing their applicability to design and to lubrication investigations related to future high performance Navy gearing. While great progress in understanding the parameters of importance in elastohydrodynamic lubrication has been made, workable solutions for use in normal design are available only for limited conditions which are realized in rolling contact when little or no sliding occurs. In gearing, this condition exists only at the pitch point so that theoretical prediction of oil-film thickness becomes increasingly overly optimistic as tooth contact distance from the pitch line (and thus sliding velocity) increases.
