Q2. For the shaft of a gearbox, 2-D views for which are shown in fig. 2, find the internal forces and moments in the shaft at the mating region for gear C for the three locations specified below. Both gears are to be assembled from the right end of the shaft due to sensor requirements and retained axially using retaining rings. Brg. A (Roller Bearing) Z y 1500 lbf Notes: Width of each bearing = 1" : Width of each gear = 2". 8" Gear B y A 2000 lbf Gear B Electromagnetic Axial Load varying cyclically from 4 to 6 kips, acting on the shaft. Figure 2a. Shaft layout. See fig. 2 for additional loading information. R=4" 10" Cyclic Axial Load not shown (a) Gear C Z F 6" R=6" 1000 lbf Gear C Brg. D (Ball Bearing) (b) Figure 2b. Forces on both gears in the vertical plane looking from right end of the shaft). Axial loading not shown. Internal forces and moments are needed at the following locations: 1. Step region for gear C 2. Mid-plane of the key-way region for gear C. To ensure the adequacy of design, consider section planes just to the right and just to the left of the mid-plane. Take the section plane that has the higher internal torque. 3. Retaining-ring groove region for gear C. Expect the groove to be narrow. Q2.
