正齿椭圆齿轮的实体建模及其运动特性分析

Solid Modeling and Meshing Motion Characteristic Analysis of Elliptical Gear

针对椭圆齿轮齿廓生成复杂且造型困难的问题,本文依据齿条刀具范成法加工非圆齿轮的原理,建立了计算机仿真加工中刀具与椭圆齿坯间的运动学模型;由此根据齿条刀具加工中齿廓形成的规律,编写出椭圆齿轮齿廓的计算程序,该程序可方便地计算出椭圆齿轮齿廓曲线数据;最后将该齿廓曲线数据导入实体造型软件完成实体建模,并运用Adam s软件分析了椭圆齿轮的啮合及运动特性。

Kinematic model of simulated motion of cutter between elliptical gear blanks is established based on the theory of envelope cutting non-cylindrical gear of rack cutter. Calculation program on tooth curves of elliptic gear is written to calculate and obtain the curve data based on constructing principle of elliptic gear tooth profile during the process of cutting rack cutter. Furthermore the introduction of curve data to a solid modeling system can help solid modeling and meshing motion analysis of elliptical gear in the Adams software.
