山东大学硕士学付论文摘要 山东大学硕士学付论文 摘要 本文在详尽总结ZK蜗杆研究现状的基础上，抓住“其齿形不仅与蜗杆参 数(m，乙西)有关，而且还与刀具的参数有关”这一有别于其他圆柱蜗杆参数的 显著特点，采用计算机仿真技术模拟ZK蜗杆实际加工过程。根据仿真加工结果， 来分析ZK蜗杆齿廓形状随蜗杆参数(m，z’dJ)和砂轮半径变化的规律，从而为 实际生产加工ZK蜗杆提供参照。论文主要包括以下几个方面的内容： (1)基于锥面砂轮包络加工ZK蜗杆的原理，推导出了ZK蜗杆的齿廓方 程，编写了ZK蜗杆理论齿形的生成程序。 (2)基于ActiveX Automation技术，利用Visual Basic对AutoCAD进行二 次开发，通过布尔运算实现了ZK蜗杆的三维加工仿真。 (3)将ZK蜗杆的理论齿形与三维仿真加工齿形进行比较，得出了误差分 布规律，并分析了误差形成的原因。 本文的研究成果对ZK蜗杆的生产加工具有较大的实践价值。另外本文还对 AutoCAD三维造型平台的误差进行了研究，这对于仿真加工的精度控制十分关 键。 关键词：ZK蜗杆齿形误差布尔运算仿真加工 Ⅲ 山东大学硕士学竹论文ABSTRACT 山东大学硕士学竹论文 ABSTRACT In this dissertation．on the basis of the full and accura把summing-up of the research status quo of the ZK_type worln，and∽cofding to its larruping砌t_一its tooth profile not only bears on wornl parameters(m，z√幽)but also tool parameters， using computer technology simulated the real machining process of the ZKJype worm．According to the results of the simulation，it is analysed that the change trend of the ZK_type worm tooth profile follows both worm parameters(m，二dd and tool parameters．Consequently,references to the real machining process of the ZK_type worm is put forward．The main contents as follows was presented： (1)Based 011 the principle that the cone grinding wheel process the ZK type worm，the equation of the tooth profile was gained and the theoretic programme of the tooth profile creation was writexl． (2)Based on the technology of the ActiveX Automation,AutoCAD was exploited secondly by Visual Basic and the three—dimensional simulation of the ZK_type worm machining was realized by boolean operation．一 (3)Compared the the theoretic tooth profile with the shape of the simulation profile，the distributing law of errors was drew on and the reasons was analysed． The conclusions in this thesis is valuable for the manufacture of ZK_type wornl． In addition，the errors of the AutoCAD design system was studied，which was pivotal to the control of m∽Mning simulation precision． keywords：ZK_type woHn tooth profile elTor boolean operation machining simuhtion IV 原创性声明本
