Chapter 13, Problem 20P

A compound reverted gear trains are to be designed as a speed increaser to provide a total increase of speed of exactly 45 to 1. With a 20° pressure angle, specify appropriate numbers of teeth to minimize the gearbox size while avoiding the interference problem in the teeth. Assume all gears will have the same diameter pitch.

Design a two-stage compound spur gear train for an overall ratio of approximately17+01:1. Specify tooth numbers for each gear in the train.
The parallel shafts are connected with two full depth spur gears, with a pinion module of 4 mm. The pressure angle is 25 degree. The number of teeth of the gear is 52. The angular speed ratio is desired as 2,6. Calculate the pitch line velocity (m/s) where the angular speed of the pinion is 2600 rev/min.
A 4 module, 20◦ pinion of 36 teeth drives a gear of 72 teeth. a. Calculate the length of action and contact ratio if the gears in mesh with zero backlash.b. If the center distance is increased 0.8mm,calculate the radii of the operating circles, operating pressure angles and backlash produced.c. Check if interference occurs
