| To R.{Sir Henry Royce} (Contd). -2- Hs{Lord Ernest Hives - Chair}/Rml/T12.11.26. We have also carried out tests running bearings with a mean oil entering temperature of 100°C. The average load at which failure occurs under these conditions is no higher than when oil is supplied to the bearing at 30°C though the mean running temperature of the bearing is increased by about 20°C. We have also been conducting some tests to determine the effect of reduced oil pressure on bearing life. Our tests so far shew that oil pressure can be reduced from 25lbs/sq.in. to 5 lbs/sq.in. without appreciably affecting the life of the bearings. Hs{Lord Ernest Hives - Chair}/W.A.Robotham. | ||
