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 design criteria.

Do you agree with your colleague that you can state that the 0.75 inch wide journal bearing would exceed Trumplers Design criteria and that no additional analysis is required? Justify your answer.

A shaft cycles such that each bearing undergoes the radial loads of 30% of the time at 20kN, 50% of the time at 25kN, and 20% of the time at 30kN. If the design life of a bearing is to be at least 5e6 revolutions, select the smallest 03 series cylindrical roller bearing that will accomplish this.

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...

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,...
