Introduction
The standard profile form in cylindrical
gears is an involute. Involutes are
generated with a trapezoidal rack — the
basis for easy and production-stable
manufacturing (Fig. 1).
At the dawn of the Industrial
Revolution, so-called mechanics
were tasked with devising the precise methods that would make mass production possible. The result was the first generation of machine tools, which in turn required improved tooling and production methods.
The name Gleason is practically synonymous with gear manufacturing. Since the company was founded in 1865, the technology of gear manufacturing has
been its focus, its core and its competitive advantage.
