Determine an appropriate combination of materials, hardnesses, and manufacturing precision for the gears in Problem 16.22. (State any necessary decisions and assumptions. Refer to Figure P16.25D.)
Problem 16.22
A pair of straight-tooth bevel gears mounted on perpendicular shafts transmits 50 hp and 1500 rpm of the 30-tooth pinion. The gear has 60 teeth. Face width is 3.0 in., P = 6, and φ = 20°. The gear is mounted in the center of a simply supported shaft with a 6-in. span between bearings. Thrust is taken by the bearing having the lighter radial load. Output torque is taken by a flexible coupling connected to a driven machine. Make a sketch of the gear and shaft assembly as a free body in equilibrium.
