根据渐开线齿轮的形成原理和齿轮啮合原理推导出包含齿根过度曲线的齿轮齿廓曲线的参数化数学模型,在MATLAB中分模块编写精确齿廓曲线、轴孔曲线的程序,根据输入不同的齿轮参数自动生成多种齿轮的两端面轮廓、引导线、齿轮轴孔轮廓和键槽轮廓的数据点并存储在ibl格式文件中,将ibl格式文件修改后导入Pro/E,通过简单处理便可生成全参数化精确直齿圆柱齿轮或斜齿圆柱齿轮的三维模型,从而大大提高了齿轮设计的精度和效率,并为后续的齿轮仿真分析奠定基础. 相似文献

根据弧齿圆柱齿轮加工原理及其齿面方程,利用UG/Open Grip二次开发语言在UG中完成齿轮的参数化建模,并实现齿轮副的装配。应用ADAMS对齿轮副进行动力学仿真,得到其在传动过程中部分参数特性曲线并对其进行分析。鉴于目前关于弧齿圆柱齿轮的研究没有成熟的动力学分析成果及计算理论,故将分析结果与同样参数的直齿、斜齿圆柱齿轮的理论计算值进行对比。结果表明:三者周向力、径向力及法向力比较接近,弧齿轮副的轴向力呈对称分布,虽然瞬时值较大但其平均值接近于零。研究结果为弧齿圆柱齿轮的动态特性研究和参数优化提供了技术支撑和理论指导。 相似文献

This paper describes an interactive program to design internal gear pairs. From a specification, the program first performs a kinematic analysis to determine tooth numbers and to satisfy centre distance requirements, and then proceeds to calculate the facewidth. It is possible to call up any design standard in order to stress the gears; that used here is the British standard. Calculated facewidths are compared with design practice and, if outside accepted bounds, the program will after tooth numbers, or module or request a change in gear material. A complete design is provided, which includes all the necessary information for manufacture. Where the design specification places tight tolerances on centre distances and/or gear ratios, the program automatically makes the required centre distance and tooth profile corrections. On every occasion the program will find a satisfactory solution, or guide the user towards one. The program is flexible and allows the experienced designer maximum freedom to direct the design. The program contains many built-in databases, such as standard tooth cutters and material properties, and will draw the gear pair if required.
The paper describes the design method and the structure of the program and a sample design is given and compared with a manual design to the same requirement. 相似文献

A mathematical model for a ZE-type worm gear set is proposed. The characteristics of a ZE-type worm gear cut with an oversize hob cutter are investigated. Bearing contacts and kinematic errors in the ZE-type worm gear set due to regrinding of oversize hob cutters are also studied. Bearing contacts in the worm gear set were obtained using surface separation topology techniques and tooth contact analysis. It was found that bearing contact locations are sensitive to the hob cutter setting angle and setting distance. Kinematic error minimization was achieved modifying worm normal tooth angle. By applying the optimization theorem and computer simulation programs, optimum hob cutter settings and worm normal tooth angle were determined to improve bearing contact location and minimize the worm gear set kinematic errors. A numerical example is given to demonstrate the results of the investigation. The developed computer-aided manufacture program has successfully been applied to the worm gear manufacture and hob cutter design. 相似文献
