When a job calls for designing nonstandard gearing, you might crunch through the AGMA or ISO calculations or turn to one of several gear-design programs. The KISSsoft 08/2005 package is a better ...

Invention of the gear-hobbing process about 150 years ago revolutionized not only gear fabrication, but also gear design. Basically, a hob or shaper cutter traverses the gear blank to generate teeth.

As one gear turns, the other gear must also turn. Where the gears meet, the teeth must both move in the same direction. In the diagram, the teeth of both gears move upwards. This means that the gears ...
