11 3 A Shaft Running At 900 R Min Is Supported In A Bear Ing Of Heavy Construction Which Is 50 Mm In Diameter And 75 Mm 1 (28.95 KiB) Viewed 15 times

11.3 A shaft running at 900 r/min is supported in a bear- ing of heavy construction which is 50 mm in diameter and 75 mm long. The bearing surface temperature is to be limited to 55°C, whilst the ambient temperature is 25°C. The oil has a kinematic viscosity of 12 mm²/s at the ope- rating temperature. The diametral clearance is 0,055 mm and the bearing is to operate without artificial cooling. Determine the permissible load and the power loss for the bearing. [3 996 N;43 W]
