【摘要】 螺旋锥齿轮具有传动性能优良,承载能力高的优点,克林贝格摆线锥齿轮是一种最具代表性的螺旋锥齿轮齿制,除具有一般螺旋锥齿轮的优点外还具有以下的特点:(1)采用连续分度双面法铣齿,避免了跳齿分度,有利于提高加工精度。(2)采用特殊结构的双层万能刀盘,通过调整内外刀盘的中心偏距可方便的控制齿面接触区。(3)可以进行硬齿面刮削加工,省去了复杂的磨齿工艺。(4)可在同一机床上实现粗精加工有利于减少设备投资。鉴于克林贝格摆线锥齿轮的这些优点,在重矿、冶金石油机械等大型机械中采用该种齿制的螺旋锥齿轮具有良好的技术优势和经济性。但由于克林贝格摆线锥齿轮是由国外引进的,设计计算工作主要依靠随机附带的软件进行,致使该种齿制齿轮的前期设计工有一定的局限性。所以,对克林贝格摆线锥齿轮的设计过程和加工原理进行分析,开发专门的计算机辅助设计及仿真系统,对促进其推广应用,提高设计生产效率,具有实际意义。本文通过分析克林贝格摆线锥齿轮铣齿原理和几何设计及制造的基本理论,推导验证了其几何设计算法及冠轮齿面方程。利用面向对象的Visual Basic 6.0编程语言为开发工具,编制了克林贝格摆线锥齿轮计算机辅助设计计算程序模块;再进一步以AutoCAD2004为软件图形系统开发平台,基于ActiveX Automation技术,编制了摆线锥齿轮参数化绘图及仿真程序模块,最终形成一套可靠、实用、方便的克林贝格摆线锥齿轮计算机辅助设计与仿真软件系统。主要研究工作和成果有:(1)通过分析克林贝格摆线锥齿轮铣齿原理,对其部分几何设计算法进行了推导验证,并建立了适当的坐标系推导了假想冠轮的齿面方程。(2)采用面向对象的Visual Basic 6.0编程语言编制了计算机辅助设计计算模块,程序中针对部分参数采用了相应的数值计算方法进行求解,实现了克林贝格摆线锥齿轮的计算机辅助几何设计计算、受力分析、强度校核、切齿调整计算功能,并可以将数据保存于指定路径下。(3)利用ActiveX Automation技术,在AutoCAD 2004图形平台上开发了参数化更多还原

【Abstract】 Spiral bevel gear presents serials of good performance at transimision, carrying capability etc, of which Klingelnber cycloid bevel gear is mostly widely used. It has its own characteristics:(1)The concave and convex flanks of the gear slot are cut at the same time continuously,this benefit to improve productivity.(2)Universal double cutter heads are used which make it easier to control the tooth contact area.(3)”HPG”cutting method is used to gain a high stress gear with hard tooth flank.(4)Rough cutting and accurate cutting can be completed at the same machine which saves the investment.Since Klingelnberg cycloid bevel gear has these characteristics, it has special advantages and economic benefit for machines in mine, metallurgy and petroleum.Because the design work of this kind of bevel gear mainly depends on software which is attached to the machine imported from abroad, we still have certain limits of its use. So analyze the design theory and cutting principle of this kind of spiral bevel gear and work out a specific computer aided design and modeling system to complete the design calculation and the simulation of the gear will promote the wide use and benefit to raise productivity of the cycloid bevel gears.In this paper, the machine cutting theory and design algorithm of Klingelnberg cycloid bevel gear were studied. The formula of the geometry design were deduced and given. Using object-oriented Visual Basic 6.0 program language as the implement tool, the computer aided calculation module for geometry parametr was implemented. Then based on ActiveX Automation technique, the parametric drawing and modeling module was implemented on AutoCAD2004 platform. Finally achieve a computer aided design and modeling system with comprehensive, reliable, practical and convenient characteristics. The main research work in the thesis is as follows:(1)Base on the analysis of cutting principle and tooth geometry characteristics of Klingelnberg cycloid bevel gear, the formula of tooth design calculation was verified and the equation of imaginary crown gear tooth flank was deduced by establishing appropriate coordinate system.(2)By using object-oriented Visual Basic 6.0 program language the computer aided calculation module was implemented. Numerical computation method was used in the calculation process of some parameters. The module can finish the tooth geometry parameter calculation, stress analysis calculation, stress checking calculation, cutting parameters calculation. Datas can be saved at the designated path.(3)The parametric drawing and modeling module for Klingelnberg cycloid bevel gears was implemented on AutoCAD 2004 platform based on ActiveX Automation technique. Drawings can be saved at the designated path and can be browsed.(4) The modularization, parameterization and function-opening design philosophy is proposed and make the software system easier to be expanded or transplanted.
