Question

The shaft in the figure below is part of a drive for an automated transfer system in a metal stamping plant. Gear Q delivers 30 hp to gear B. Sheave D delivers the power to its mating sheave as shown. The shaft carrying B and D rotates at 550 rpm. Use SAE1040 cold drawn steel.

Note: Torque on gear at B and the torque on sheave at D are equal.

Gear Data:

- NB= 96 (Number of teeth on gear B)

- Pd= 6 (Diametral pitch for gear B)

- Spur gears Gear pressure angle =20o

- Shaft at B and D rotate at 550 rpm.

Use the following assumptions:

- Bearing seats have sharp fillets. Kt=2.5

- Design factor (Factor of Safety) = 3

- Pinion Q is rotating in CCW direction.

- Cs= Size factor = 0.80

a) Determine the magnitude of the torque in the shaft at all points

b) Compute the forces acting on the shaft at all power-transmitting elements

c) Compute the reactions at the bearings
