Rough Forming of Ring Gear by Indentation of a Rack-Shaped Punch : Experimental Investigation

概要

論文の詳細を見る
Successive indentations of ring-shaped lead specimens by a rack-shaped punch are investigated experimentally by various methods to form the teeth of ring gears. Most of the indented materials are found to flow in the circumferential direction to cause an increase in the ring diameter. In order to produce ring gears with moderate accuracy, it is most important to conform the acting surface of the work holder to the current inner surface of the ring during indentation. The roundness error and pitch error of the produced ring gears are also examined by using the approximated correction method.
