摘要/Abstract

摘要：

针对目前准双曲面齿轮冷摆辗技术存在模具结构复杂、摆辗力相对较大等问题,提出了一种新型的冷摆辗方法。该方法简化了模具结构,采用局部线接触连续塑性成形。基于刚塑性有限元法基本理论,借助通用三维有限元软件DEFORM-3D对准双曲齿轮摆辗成形全过程进行了三维动态分析,研究了速度场量、接触区以及模具受力的分布和变化规律。研究结果揭示了准双曲面齿轮冷摆辗的变形规律。

Abstract:

At present, the cold rotary forging technology of hypoid gears existed problems such as very complex die structure and bigger rotary forging force, therefor the authors put forward a new type cold rotary forging technology. The method simplified the die structure, adopted the local line contact continuous plastic forming. Based on the basic theory of rigid-plastic finite element(FE) method, a three-dimensional dynamic FE simulation model of the whole process of hypoid gear cold rotary forming was analyzed by means of a common three-dimensional finite element software Deform-3D V6.0. The distribution and variation laws of velocity field, contact zone and die stress were investigated. The results of this research reveal the deformation mechanism of cold rotary forging for hypoid gears.

Key words: camion driving axle gear;cold rotary forging, numerical simulation;anti-fatigue manufacturing;hypoid gear
