Chapter 11, Problem 11.32(choose chapter or problem)
The figure shown is a geared countershaft with an overhanging pinion at C. Select an angularcontact ball bearing from Table 112 for mounting at O and an 02-series cylindrical roller bearing from Table 113 for mounting at B. The force on gear A is FA 5 600 lbf, and the shaft is to run at a speed of 420 rev/min. Solution of the statics problem gives force of bearings against the shaft at O as RO 5 2387j 1 467k lbf, and at B as RB 5 316j 2 1615k lbf. Specify the bearings required, using an application factor of 1.2, a desired life of 40 kh, and a combined reliability goal of 0.95, assuming distribution data from manufacturer 2 in Table 116.
