Chapter 11, Problem 22P

11-22 to 11-26 An 02-series single-row deep-groove ball bearing is to be selected from Table 11-2 for the application conditions specified in the table. Assume Table 11-1 is applicable if needed. Specify the smallest bore size from Table 11-2 that can satisfy these conditions.

Problem Number Radial Load Axial Load Design Life Ring Rotating Desired Reliability
11-22 8 kN 0 kN 109 rev Inner 90%
11-23 8 kN 2 kN 10 kh, 400 rev/min Inner 99%
11-24 8 kN 3 kN 108 rev Outer 90%
11-25 10 kN 5 kN 12 kh, 300 rev/min Inner 95%
11-26 9 kN 3 kN 108 rev Outer 99%

A certain application requires a ball bearing with the inner ring rotating, with a design life of 26 kh at a speed of 455 rev/min. The radial load is 2.5 kN and an application factor of 1.2 is appropriate. The reliability goal is 0.92. Find the multiple of rating life required, xD , and the catalog rating C10 with which to enter a bearing table. Choose a 02-series deep-groove ball bearing from Table 11–2 and estimate the reliability in use.
Select an angular contact ball bearing to carry a radial load of (336+ID) lb at a shaft speed of 1800 rpm for 5500 hours. An application factor of 1.2 is appropriate. Use a reliability of 96%. (ID = 007)
Consider the belt drive having a diameter of 150 mm that is mounted on the overhung end of ashaft, 30 mm from the nearest bearing. The stepped shaft is made of steel having Su = 965 MPa(140 ksi). The shaft diameter, d, is 30 mm. The bearing bore, D, is 36 mm. The fillet with amachined surface has a radius, r, of 3 mm. What is the safety factor with respect to eventualfatigue failure of the shaft?
