Question
A full journal bearing has a nominal diameter of 60.0 mm, a bearing length of 30.0 mm and
supports a load of 3200 N when running at the design speed of 3200 rpm. The radial clearance
has been specified as 0.04 mm. An SAE 20 oil has been chosen and the lubricant supply
system is capable of delivering the lubricant to the bearing at 60oC. Using the Raimondi and
Body design charts;
1.1 find the temperature rise of the lubricant, (19)
1.2 the total flow rate required, (1)
1.3 the torque required to overcome friction (3)
1.4 and the power dissipated in the bearing.
