You are asked to design a plain surface journal bearing to carry a steady radial load of 5.25 kN while the shaft rotates at 1080 rpm. The shaft stress analysis determines that an acceptable diameter of the journal is ds = 62.5±0.008 mm, a %| bushing with a diameter dn = 62.6±0:308 mm, and an l/d ratio is 1.. We shall use %3D SAE 40 oil as a lubricant, at an inlet temperature of 45 °C. The shaft is part of a machine requiring good precision, so for a minimum radial clearance (Cmin) analyze the hypothetical bearing,

Question
You are asked to design a plain surface journal bearing to carry a steady radial load of 5.25 kN while the shaft rotates at 1080 rpm. The shaft stress analysis +0.000 determines that an acceptable diameter of the journal is ds 62.5* -0.050 mm, a bushing with a diameter dn = 62.6+0.100 -0.000 mm, and an l/d ratio is 1.. We shall use SAE 40 oil as a lubricant, at an inlet temperature of 45 °C. The shaft is part of a machine requiring good precision, so for a minimum radial clearance (Cmin) analyze the hypothetical bearing, c) Determine the power loss, Hloss in [W], friction torque, Trin [N-m] d) For minimum radial clearances, perform a design assessment using Trumpler's
