The shaft in Figure 1-2 is a part of a drive for an automated transfer system in a metal stamping plant. The shaft rotating at 402.62 rpm carries a spur gear B having 96 teeth with a diametral pitch of 6. The teeth are of the 20, full-depth, involute form. Gear Q delivers 15.262kW to gear B, Sheave D

The shaft in Figure 1-2 is a part of a drive for an automated transfer system in a metal stamping plant. The shaft rotating at 402.62 rpm carries a spur gear B having 96 teeth with a diametral pitch of 6. The teeth are of the 20°, full-depth, involute form. Gear Q delivers 15.262kW to gear B, Sheave D delivers the power to its mating sheave as shown. Use AISI 1040 cold drawn steel. You are required to: a) Draw the shaft with your dimensions b) Carry out a force analysis to determine the forces including acting on the shaft at all power transmitting elements c) Compute reactions at the bearings d) Draw the complete torque, shear, and bending moment diagrams e) Give a suggested geometry at point C of the shaft and specify the minimum acceptable diameter for the shaft at this point with implementing a design factor of 2.762 Neglect the weight of the elements on the shafts, unless otherwise noted. 256.62 mm Q- B- B 256.62 mm C 406.4 mm dia. spur gear 20°FD Qdrives B B D D 155.02 mm 254 mmdia.
