1. The shaft rotating at 200 rpm carries a spur gear C having 80 teeth with a diametral pitch of 8. The teeth are of the 20°, full-depth, involute form. The gear delivers 6 hp to a pinion directly below it. Pulley A receives 10 hp from below. The chain sprocket D delivers 4 hp to a shaft above. Compute the torque delivered by the shaft to gear C and the tangential and radial forces exerted on the shaft by the gear. The pitch diameters of the flat belt sheave, spur gear, and the chain sprocket are 20 in., 10 in., and 6 in., respectively. Ans: TA 3150 in-lb, To = lb, W, 137.6 lb = = TD 1890 in-lb, Tp = 1260 in-lb, W₁ = 378

Shaft Design by Code
1. The shaft rotating at 200 rpm carries a spur gear C having 80 teeth
with a diametral pitch of 8. The teeth are of the 20°, full-depth, involute
form. The gear delivers 6 hp to a pinion directly below it. Pulley A
receives 10 hp from below. The chain sprocket D delivers 4 hp to a shaft
above. Compute the torque delivered by the shaft to gear C and the
tangential and radial forces exerted on the shaft by the gear. The pitch
diameters of the flat belt sheave, spur gear, and the chain sprocket are 20
in., 10 in., and 6 in., respectively.
Ans: TA = 3150 in-lb, To = 1890 in-lb, TD= 1260 in-lb, Wt
lb, W, = 137.6 lb
= 378
