Prediction of Deformation and Load in Gear Forging
기어단조시 변형과 하중의 예측
Abstract
As high capacity and precision forging presses have become available, it is possible to manufacture gears by forging technology. In gear manufacturing by forging, however, there are problems of designs of ides and preforms. In the present paper, two exampels are presented to show how the rigid plastic finite element method can be utilized to overcome the problems. The examples are spur gear forging and interanl-apline gear forging. Both analyses are three dimensional using eight node linear block elements with approximation that the involute curve can be represented by lines and arcs. Results of the analyses include metal flow in dies and required load during forging which aid to decide proper designs.
