Question

A full journal bearing has a journal diameter of 34 mm, with a unilateral tolerance of -0.012 mm. The bushing bore has a diameter of34.05 mm and a unilateral tolerance

of 0.032 mm. The bearing is 68 mm long. The journal load is 1 kN, and the journal runs at403.7907 rev/min. Using an average viscosity of 55.6 mPa-s, find the minimum film thickness, the maximum film pressure, and the total oil-flow rate for the minimum clearance assembly. The minimum film thickness ismm. The maximum film pressure is___Mpa. The total oil-flow rate for the minimum clearance assembly is___mm3/s.
