Unformatted text preview: ME 3365 Introduction to Design Homework 5 (Due: March 15, 2008) l. A 2 1/2 X 2 V2 -in sleeve bearing uses grade 20 lubricant. The axial-groove sump has a steady state temperature of HOT. The shaft journal has a diameter of 2.5 in with a unilateral tolerance of -0.001 in. The bushing bore has a diameter of 2.504 in with a unilateral tolerance of 0.001 in. The journal speed is 1120 revfmin and the radial load is 13 00 lbf. Estimate (a) The magnitude and location of the minimum oil-film thickness. (b) The eccentricity. (e) The coefficient of friction. (d) The power loss rate. (e) Both the total and side oil-flow rates. (f) The maximum oil—film pressure and its angular location. (g) The terminating position of the oil film (h) The average temperature of the side flow. (i) The oil temperature at the terminating position of the oil film. 2. A compound gear train as shown in the following figure, Gear 1 has 24 teeth and Gear 2 has 7’0 teeth of diametral pitch of 4. Gear 3 has 30 teeth and Gear 4 has 50 teeth of diamerral pitch of 3. Gear 1 turns 12 rpm in clockwise direction. (a) Computer the speed and direction of the shaft carrying Gear 4. (b) Find the torque at Shaft c if the input horsepower at Shaft a is 50?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
