Figure P14.28 shows two bearings supporting a 1000-rpm shaft and gear. The bearing on the left carries a 5-kN radial load and 1-KN thrust load. The loading is borderline between "light" and "moderate" impact. The required life is 5000 hours with only 2% probability of failure.

QUESTION-3 Shaft shown in the figure is supported by A and C bearings. Bearing A has 4300 N radial and 1400 N axial force due to the tooth force of the gear wheel on the shaft. Only a radial force of 3100 N acts on bearing C. The shaft diameters are the same in the region where the A and C bearings are located and dA = dC = 35 mm The rotation speed of the spindle is...

(5) The gear reduction unit shown has a gear that is press fit onto a cylindrical sleeve that rotates around a stationary shaft. The helical gear transmits an axial thrust load of 300 Ibf as shown in the figure. Tangential and radial loads (not shown) are also transmitted through the gear, producing radial ground reaction forces at the bearings of 900 lbf for bearing A and 650 lbf for bearing B. The desired life for each bearing is 90 kh...
