INVESTIGATION OF 75-MILLIMETER-BORE CYLINDRICAL-ROLLER BEARINGS AT HIGH SPEEDS III – LUBRICATION AND COOLING STUDIES - OIL INLET DISTRIBUTION, OIL INLET TEMPERATURE, AND GENERALIZED SINGLE-OIL-JET COOLING-CORRELATION ANALYSIS

摘要

Oil inlet distribution was found to be an important factor in the lubrication and cooling effectiveness of a given quantity of oil.nOil supplied by multiple Jets (nonopposed) produced appreciably lower inner-race temperatures, outer-race temperatures, and outer-race circumferential temperature gradients at a given oil flow than did oil supplied by a single-jet, single-opposed-jet, multiple-opplosed-jet, or outer-race-hole distribution,,nOil supplied by single-opposed jets produced lower inner-race and outer-race bearing temperatures at a given oil flow than did oil supplied by a single jet, particularly at low oil flows.
