TOOTHED TOOL AND DEVICE FOR CHIPLESS GENERATION OF GEARS

摘要

A toothed tool for the chipless generation of gears of the type wherein the teeth have pressure concentrating serrations extending from at least near the addendum thereof to a point at least near the dedendum thereof. These serrations define ribs on the toothed flanks by which the pressure part of the tool is transmitted in a concentrated manner onto the workpiece. In the present invention, the tool is of generally elongated or rack-like shape and moves substantially rectilinearly with respect to the periphery and teeth of the workpiece. Any suitable means are provided to create the necessary pressure between the tool and the workpiece.
