D Question 6 2 pts Estimate the minimum oil film thickness (m) in a sleeve bearing (B- 360°) carrying a design load of 3 kN at a rotational speed of 600 rev/min. The bearing diameter is d 44 mm, the bearing length is I 0.6d and the diametral clearance is 1 um per mm of the bearing diameter d. The bearing operates at a Sommerfeld number of S-0.2

5) [10] A journal bearing has a journal diameter of 75 mm with a unilateral tolerance of - 0.075 mm. The bushing bore has a diameter of 75.15 mm and a unilateral tolerance of 0.1 mm. The busing is 75 mm long and supports a 2585 N load. The journal speed is 750 rev/min. Find the minimum oil film thickness and the maximum film pressure for SAE 20W lubricant at an operating temperature of 65 °C for the minimum clearance...

PROBLEM 2 and 3 (journal bearing) A gear-reduction unit uses the countershaft depicted in the figurel. The reactions at bearing positions and C, are shown in figure 2. Note that only bearing position take the axial load. The bearing at position is to be angular-contact ball bearings, having a desired life of 50 kh when used at 300 rev/min. Use 1.2 for the application factor and a reliability goal for the bearing pair of 0.96, assuming distribution data from manufacturer...

A journal bearing 4 inches in diameter and 4 inches long has a
radial clearance of 0.002 inches. It rotates at 2000 rpm and is
lubricated is SAE 10 oil at 200F. In the following, use an applied
load of 225 lbs and neglect temperature rise.
a. Estimate the power loss and the friction torque using the
Petrov equation. Calculate the coefficient of friction.
b. Calculate the minimum clearance, the power loss, friction torque
and the coefficient of friction using...
