You are asked to design a plain surface journal bearing to carry a steady radial load of 5.75 kN while the shaft rotates at 950 rpm. The shaft stress analysis determines that an acceptable nominal diameter of the journal is 62.5-mm and an l/d ratio is 1. The shaft is part of a machine requiring good precision. So a minimum radial clearance cmin= 0.040 mm seems appropriate. We shall use SAE 30 oil as a lubricant, at an inlet temperature of 45 oC. Analyze the hypothetical bearing,a) Determine the operating temperature Tave, and operating viscosity μave. b) Determine the minimum film thickness, ho, temperature rise of the lubricant, ΔTC, the total oil flow, Q, and side flow Qs in [mm3/s], the maximum film pressure Pmaxdeveloped in [MPa]. c) Determine the power loss, Hloss in [W], friction torque, Tf in [N-m] d) For minimum radial clearances, perform a design assessment using Trumpler’s criteria.

An multi axial plate clutch used in injection molding machine consist of a three pairs of contact surfaces for engaging and disengaging power from the engine. The engine used for power has a maximum torque capacity of 120 N-m and is transmitted to machine without losses. The permissible intensity of pressure is 350 kPa and the coefficient of friction is 0.35 for the clutch system used in the machine. It was determined that the machine will operate on maximum capacity of torque if the ratio of inner diameter to outside diameter of the axial clutch is 0.577.
