渐开线变位齿轮的参数化建模及分析

Parameterized Modeling and Analysis of Involute Profile Shifted Gear

渐开线变位斜齿轮的建模过程复杂,特别是端面渐开线齿廓的准确绘制和螺旋扫掠线的精确控制,可以用编程方法来实现,但要求相关专业知识做支撑。本文采用的另一方法是利用UG软件的表达式和规律曲线设计功能,根据齿轮的设计原理对渐开线变位斜齿轮精确建模,并且可以实现参数化控制。在此基础上,针对变位齿轮几何模型进行了有限元分析。

It is complex on the modeling process of oblique profile shifted gear in implementation of its terminal face in-volute profile and manipulation of its tooth spiral sweeping centerline,in which it must demands specialized knowledge to designers by procedural programming method.Another concern on the subject in this paper is the utilization of curve formula function on UG,in which precision modeling of the oblique profile shifted gear and the parameterized control-ling can be realized on the principle of gear design,and numerical analysis of the oblique profile shifted gear model was examined by finite element method.
