Summary

Oil inlet distribution (5 methods were investigated) and oil inlet temperature (100 to 205 degrees F) were found to be significant factors in the cooling effectiveness of a given quantity of oil. Dimensional analysis was used to generalize the test-rig results so that it is possible to predict the inner- or outer-race temperatures above the oil inlet temperature from a single curve regardlesss of whether speed, load, oil flow, oil inlet temperature, oil-jet diameter or any combination of the parameters is varied.
