Ex: The second shaft on a parallel-shaft 25-hp foundry crane speed reducer contains a helical gear with a pitch diameter of S.08 in. Helical gears transmit components of force in the tangential, radial, and axial directions. The components of the gear force transmitted to the second shaft are shown in Fig. (8) at point A. The bearing reactions at C and D, assuming simple- supports, are also shown. A ball bearing is to be selected for location C to accept the thrust, and a cylindrical roller bearing is to be utilized at location D. The life goal of the speed reducer is 10 kh, with a reliability factor for the ensemble of all four bearings (both shafts) to equal 1 (90% reliability) with light to moderate impact. (a) Select the roller bearing for location D. (b) Select the ball bearing (angular contact) for location C, assuming the inner ring rotates. *- 20 Fig (8)

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 T of 1000 N 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 3200 N for bearing A and 2400 N for bearing B. The desired life for each bearing is 100 kh at a speed of 180 rev/min with a 90 percent reliability. The first iteration of the shaft design indicates approximate diameters of 30 mm at A and at B.
