Mechanical Engineering

A gearbox is to be designed with a compound reverted gear trainthat transmits 25 horsepower

with an input speed of 2500 rev/min. The output should deliverthe power at a rotational speed in

the range of 280 to 300 rev/min. Spur gears with 20? pressureangle are to be used. Assuming a diametral pitch of 6 teeth/in.Please show all steps.

(a) Determine pitch diameters for each of thegears.

(b) Determine the pitch line velocities (in ft/min) foreach set of gears.

(c) Determine the magnitudes of the tangential, radial,and total forces transmitted between each

set of gears.

(d) Determine the input torque.

(e) Determine the output torque, neglecting frictionallosses.
