A journal and bearing are to be designed for a shaft that turns at 250 rpm. Suppose
ISO VG100 (SAE Engine 30) is to be used as lubricant and the bearing length is to be equal to
1.2 times the diameter. If the no-load power loss is not to exceed 2.5 x 10-4 horsepower and the
diametral clearance is 0.0045 times the diameter, estimate the maximum diameter that can be
used for the journal, and the allowable temperature limit.

A shaft inside the sleeve of a journal bearing is being rotated at 1500 rpm. The shaft is 6.00 cm in diameter and is rotating in a bearing sleeve that is 6.02 cm in diameter and 40 cm long. The clearance is filled with oil having properties of ?=0.003 m2 /s and SG=0.88. a. Find the torque required to rotate the shaft. b. Find the power required to rotate the shaft. (Answer: 44.1 kW) c. Discussion: How do the torque...

all journal bearing has a shaft diameter=1.25in and suppports a load of 1200lbf. the bushing is 1.25-in long and has a bore diameter=1.25in. shfat speed=1500 rev/min. average film temperature=115.4oF and SAE grade 30 lubricant is used. average clearance =0.001125 in. Find a) magnitud and location of min oil-film thickness b) total lubricant volumetric flow rate c) max oil-folm pressure and its angular location d) power loss

A .05 wide journal bearing supporting the loads on a 1 inch shaft just meets the Trumpler’s design criteria for a FACTOR OF SAFTY OF 2.05. The bearing satisfies all the other Trumpler’s design criteria by much larger margin. Your colleague suggests that increasing the bushing width to 0.75 inches would be an adequate design and you would not need to conduct another journal bearing analysis because the greater width would result in a bearing which satisfy all of Trumpler’s...

For a marine diesel engine application, a fluid-film journal bearing has a shaft diameter of 32 mm and the length of the bearing is 24 mm. The bearing uses SAE grade 20 oil as lubricant and operates under a radial load. The inlet and outlet temperatures of oil are 50oC and 110oC respectively. It is assumed that because of the shearing action there is a uniformly distributed energy release in the lubricant that heats the lubricant film. During run-in operation,...

The J-shaped member shown in the figure is supported by a cable DE and a single journal bearing with a square shaft at A. Determine the reaction forces A_y and A_z at support A required to keep the system in equilibrium. The cylinder has a weight W_B = 5.30 lb, and F = 1.20 lb is a vertical force applied to the member at C. The dimensions of the member are w = 1.50 ft, l = 6.00 ft, and...

A horizontal shaft of 75mm diameter projects from a bearing and, in addition to the torque transmitted, the shaft carries a vertical load of 8 kN at 300 mm from the bearing. If the safe stress for the material, as determined in a simple tension test, is 135 MN/m2 find the safe torque to which the shaft may be subjected using as a criterion (a) The maximum shearing, stress, (b) The maximum strain energy per unit volume. Poisson’s ratio ?...
