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

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

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

(a) Determine pitch diameters for each of the gears.

(b) Determine the pitch line velocities (in ft/min) for each 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 frictional losses.

countershaft in Prob. 3–72, p. 152, is part of a speed reducing compound gear train using 20° spur gears. A gear on the input shaft drives gear A. Gear B drives a gear on the output shaft. The input shaft runs at 2400 rev/min. Each gear reduces the speed (and thus increases the torque) by a 2 to 1 ratio. All gears are to be of the same material. Since gear B is the smallest gear, transmitting the largest load,...

A power train application requires the coupling of a spur gear to a transmission shaft operating at 3600RPM. The coupling must sustain a mean torque loading of 215Nm. There is a 20% torque ripple introduced to the drive line from the load. Select and design a coupling system using either a keyed coupling or an interference coupling such that the section of the transmission shaft at that location is minimized. Assume that the gear is located at the midpoint of...
