A journal bearing has a shaft diameter of 75.00 mm with a unilateral tolerance of −0.02 mm. The bushing bore has a diameter of 75.10 mm with a unilateral tolerance of 0.06 mm. The bushing is 36 mm long and supports a load of 2 kN. The journal speed is 700 rev/min. For the minimum clearance assembly find the minimum film thickness, the heat loss rate, and the maximum lubricant pressure for SAE 30

QUESTION 2 A pressure-fed bearing has a joumal diameter of 55.00 mm with a umilateral tolerance of -0.05 mm. The bushing bore diameter is 50.084 mm with a unilateral tolerance of 0.10 mm. The length of the bushmg is 55 mm. Its central annular groove is 5 mm wide and is fed by SAE 30 oil is 55°C at 200 kPa supply gauge pressure. The journal speed is 2880 rev/min carrying a load of 10 EN. The sump ca dissipate 300 watts per bearing if necessary. For minimum radial clearances, find the minimum film thickness and average temperature. Given the film temperature is 85° c Attach File Browse My Computer QUE STION 3
