Question

A gear and sleeve rotate at 1500 RPM around a stationay shaft The gear generates an axial thrust force of 400 Ibf The radial reactions produced on the left and right bearings are 1050 and 500 Ibf respectively An engineer picked these single-row tapered roller bearing part numbers (PN) from Figure 11-15 in your textbeok a) left bearing cone 15101 and cup 15244 and b) right bearing cone 07100 and cup 07204 Bearings are oriented in indirect mounting style as shown Beanng seals are know to be in bad conditions For 99% reliability, calculate the expected life in hours of each bearing, Weibull parameters for this bearing manufacturer are: Xo = 0, theta = 4.48 and b = 1.5,
