The figure shown is a geared countershaft with an overhanging pinion at C. The force on gear A is FA = 600 lbf, and the shaft is to run at a speed of 490 rev/min. Solution of the statics problem gives force of bearings against the shaft at O as Ro=-387j+467k lbf and at B as RB = 316j - 1615k lbf. Use 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 11-6. Gear 3 24 dia 20 Gear 4 10 dia Obtain a basic load rating for an angular-contact ball bearing at point O. The basic load rating for an angular-contact ball bearing is kips.
