【摘要】：摆动活齿传动是一种用于传递两同轴间运动和动力的活齿传动机构,其特点是多齿啮合、承载能力强、传动效率高、传动比大等,具有很好的应用前景。随着科学技术的高速发展,工程设计人员利用参数化技术,可以大大提高只有几何尺寸发生变化的零件的设计效率,避免繁琐的重复性工作。因此,参数化技术已成为机械CAD中重要的研究内容。 本文应用摆动活齿传动的等效机构,对摆动活齿传动的结构组成、工作原理进行分析;建立了摆动活齿传动的力学分析模型,推导出摆动活齿传动啮合副受力计算公式;利用复数矢量法综合出摆动活齿中心轮的理论齿廓方程和实际齿廓方程,分析了中心轮齿廓不顶切的条件;分析了摆动活齿传动的运动状况以及结构参数对中心轮齿廓的影响。 根据开发软件和编程语言的特点,确定二次开发的平台和工具;分析主要用到的SolidWorks接口对象的功能和用户界面设计的一般原则;利用Visual Basic编程实现摆动活齿传动机构关键件的参数化设计并设计输出工程图。 建立了摆动活齿传动机构动态实体模型,分析并完成了SolidWorks和ADAMS/View之间接口文件的转换,成功转换了两者之间的几何模型;定义构件之间的运动副,施加约束和载荷,对摆动活齿传动机构进行运动仿真;通过对摆动活齿传动机构实体模型的运动仿真,分析了关键件的运动状况及啮合副受力情况。
[Abstract]:Oscillating movable teeth transmission is a kind of movable tooth transmission mechanism used to transfer motion and power between two coaxial. Its characteristics are multi-tooth meshing, strong bearing capacity, high transmission efficiency and high transmission ratio. It has a good application prospect. With the rapid development of science and technology, engineering designers can greatly improve the design efficiency of parts with only geometric changes by using parameterized technology, and avoid tedious and repetitive work. Therefore, parameterization technology has become an important research content in mechanical CAD. In this paper, the equivalent mechanism of swing movable tooth transmission is used to analyze the structure and working principle of oscillating movable tooth transmission, the mechanical analysis model of swing movable tooth transmission is established, and the formula for calculating the force on the meshing pair of swing movable tooth transmission is deduced. By using complex vector method, the theoretical and practical tooth profile equations of the oscillating tooth centerwheel are synthesized, the conditions under which the tooth profile of the oscillating tooth is not top tangent is analyzed, and the movement state of the oscillating tooth transmission and the influence of structural parameters on the tooth profile of the center wheel are analyzed. According to the characteristics of the development software and programming language, the platform and tools for secondary development are determined, and the functions of the main SolidWorks interface objects and the general principles of user interface design are analyzed. The parametric design of the key parts of oscillating movable teeth transmission mechanism is realized by Visual Basic programming and the output engineering drawing is designed. The dynamic entity model of oscillating movable tooth drive mechanism is established, the interface file conversion between SolidWorks and ADAMS/View is analyzed and completed, the geometric model between them is successfully transformed, the moving pair between components is defined, and the constraint and load are applied. The kinematic simulation of oscillating movable tooth transmission mechanism is carried out, and the motion state of key parts and the force of meshing pair are analyzed through the motion simulation of the solid model of oscillating movable teeth transmission mechanism.
