Forming Analysis and Design of Cold Gear Forging using 3D Finite Element Method
3차원 유한요소법을 적용한 냉간단조 기어 성형 해석 및 설계
Abstract
It is important to predict forming procedure for minimizing trial-and-error in the application of cold forging of gears. In this study, 3-dimensional simulations of cold forging processes of spur and bevel gear were carried out using finite element method to investigate the characteristics of the processes. From the simulation result it was found that incomplete teeth forming of spur gear was occurred with increase of teeth number in forging by forward extrusion. It can be reduced through division of material flows at the initial forming state using forward/backward combined extrusion.
