Question 3 The design of journal bearings usually involves two suitable combinations of variables: variables under control and dependent variables or performance factors. As such, a full journal bearing has a shaft journal diameter of 27 mm with a unilateral tolerance of 20.01 mm. The bushing bore has a diameter of 27.04 mm with a unilateral tolerance of 0.03 mm. The //d ratio is unity. The bushing load is 1.03 kN, and the journal rotates at 1153 rev/min. You are required to analyze the minimum clearance assembly if the average viscosity is 50 mPa.s to find the minimum oil film thickness, the power loss, and the percentage of side flow.

Another very common mode of failure of gear teeth is that due to surface damage or pitting, which can eventually result in extensive cratering and loss of the load bearing surface of the tooth. Which of the following best describes the causes, and some of the measures that can be taken to prevent this form of failure. a. Maximum compressive stresses occur at the root of the tooth; - Stress concentrations due to cracks in the tooth flank can increase these stresses; - Failure is due to fatigue loading, and is worse because of shock loads: -Asperity to asperity contact, and hence high surface roughness or poor lubrication can make this failure worse; - Surface load capacity can be improved by selecting materials with high surface hardness values, such as carburised steels; - Once pitting has occurred over more than 10 % of the surface, gears are no longer serviceable. b. Maximum tensile stresses occur at the point of contact between the teeth; - Stress concentrations due to pits or small…
