2. Ball Bearing Design & Analysis (40 points) A shaft is to be used to support a ball bearing idler pulley, as shown in the following figure. Radial load F, Bearing. Nonrotating shaft of circular cross section RL RR 8 in. 16 in. The bearing is single-row 02-series deep-groove. The inner race of the ball bearing is attached to the shaft. The rotating pulley is attached to the outer race of the ball bearing. The Weibull parameters are xo=0.020, 0 = 4.459, and b = 1.483. T he following information is given for your calculation. Rotation speed of the Radial Load on the pulley, Fr Design life of the ball bearing Reliability of the ball bearing Application factor, af pulley 1,500 lbf 1,725 rpm 1,800 hours 92% 1.0 a) Calculate the catalog rating Cio for the ball bearing (15 points) b) Select the smallest acceptable bearing (bore) from Table 11-2 (10 points) c) If the selected ball bearing in b) is used for this application, estimate the reliability of the selected ball bearing.
