The 247 6-pitch 20° pinion 2 shown in the figure rotates clockwise at 1000 rev/min and is driven at a power of 25 hp. Gears 4, 5, and 6 have 24, 36, and 144 teeth, respectively. What torque can arm 3 deliver to its output shaft? Draw free-body diagrams of the arm and of each gear and show all forces that act upon them.
The figure shows a 16T 20' straight bevel pinion driving a 32T gear, and the location of the bearing
centerlines. Pinion shaft a receives 2.5 hp at 243 rev/min. Determine the bearing reactions at A and B
if A is to take both radial and thrust loads.
