Final Exam, Spring 2oTg Grade: Student Name: Problem #1 (50 point): An SKF ball bearing has an axial load F. of 500 Ibr and a radial load F, of 600 Ibr applied with inner ring rotating. The basic...
Problem #2 (50 point): A certain application requires a ball bearing with the inner ring rotating, with a design life of 40000 hr at a speed of 350 rev/min. The radial load is 2.15 kN and an application factor of 1.3 is appropriate. The reliability goal is 0.90. Find the multiple of rating life required, Xo, and the catalog rating Cio with which to enter a bearing table. Choose a 02-series deep-groove ball bearing from Table 11-2, and estimate the...
A 02-series angular contact ball bearing with a 10-mm bore is
loaded with a 0.3604 kN axial load and 100 kN radial load. The
inner ring rotates at 8000 rev/min and working 2000-hour service.
For Rd = 93% and af = 1.
(a) Determine the equivalent radial load that will be
experienced by the bearing.
(b) Consider a rating rated life of 10^6 revolutions find C10
load experienced by bearing and calculate the factor of safety in
carrying the load...
