ABSTRACT
In this chapter the subject of the design of the gear tooth shape is covered. To the casual observer, some gear teeth appear tall and slim while others appear short and fat. Gear specialists talk about things like the “pressure angle,” long and short addendum, root —llet design, and the like. Obviously, there is some well-developed logic in the gear trade with regard to how to choose and specify factors related to the shape of gear teeth. This chapter presents the basic data that are needed to exercise good judgment in gear tooth design.
