Gear Trains and Planetary Gears
2020In this chapter, the general concepts of ordinary gear trains are first described, particularly those concerning their efficiency and the obtainable transmission ratios. The same concepts are then extended to planetary gear trains and various methods of calculating the transmissions ratios achievable with these types of gear drives are defined.

Gear Cutting II, Helical Gears
1987We showed in Chapter 14 that two helical gears mounted on parallel axes can mesh correctly together, provided their normal base pitches and transverse base pitches are equal. We can therefore use a helical pinion cutter to cut helical gears, and the normal base pitch and the transverse base pitch of the gear will then be equal to those of the cutter.

The simplest method by which a gear can be cut is to use a tool shaped exactly like the tooth space of the gear. This method of cutting gears is known as form cutting. In practice, the cutting tool is generally a milling cutter, such as the one shown in Figure 5.1. The gear blank is held stationary while the cutter is fed slowly in the direction of the
