ABSTRACT

The rewritten Design Manual for Fine--Pitch Parallel Shaft Gearing is a cookbook style manual on how to design

fine--pitch spur and helical gears.

All work has been done with an eye towards computerization of the equations and the graphs.

In addition, the manual contains such specialized subjects as inspection, lubrication, gear load calculation

methods, materials, including a wide variety of plastics.
