18-3 For the case study problem, use helical gears and design the intermediate shaft. Compare your
results with the spur gear design presented in this chapter.

Case Study Problem Specification:

Section 1–18, p. 34, presents the background for this case study involving a speed reducer. A two-stage, compound reverted gear train such as shown in Fig. 18–1 will be designed. In this chapter, the design of the intermediate shaft and its components is presented, taking into account the other shafts as necessary.

A subset of the pertinent design specifications that will be needed for this part of the design are given here.

-Power to be delivered: 20 hp
-Input speed: 1750 rpm
-Output speed: 82–88 rev/min
-Usually low shock levels, occasional moderate shock Input and output shafts extend 4 in outside gearbox
-Maximum gearbox size: 14-in x 14-in base, 22-in height
-Output shaft and input shaft in-line
-Gear and bearing life > 12 000 hours; infinite shaft life
