【摘要】：微线段齿轮是一种新型齿轮,具有承载高、效率高、寿命长等特点。为弥补对内斜微线段齿轮研究理论和加工方法的不足,文章借鉴范成法加工齿轮的思想,利用微线段齿条法面齿廓方程,通过坐标变换方法推导了内斜微线段齿轮的通用齿面方程,并证明了齿面的光滑连续性;针对上述齿面方程,通过编写计算机程序实现了基本齿廓的绘制,并导入三维绘图软件中完成三维模型的创建;利用线切割方法加工出齿轮样件,并与三维模型进行对比,结果表明线性插补法获得内斜微线段齿廓的方法可行。该研究为内斜微线段齿轮应用于高精度传动系统等相关产品的设计和制造提供了一定的理论参考和应用基础。
[Abstract]:Micro-line segment gear is a new type of gear, which has the characteristics of high bearing capacity, high efficiency and long life. In order to make up for the deficiency of research theory and machining method of internal helical micro-segment gear, this paper draws lessons from the idea of machining gear by the method of fan Cheng. In this paper, the general tooth surface equation of the inner helical micro-segment gear is derived by using the tooth profile equation of the normal surface of the micro-segment rack, and the smooth continuity of the tooth surface is proved. The drawing of the basic tooth profile is realized by writing computer program, and the 3D model is created in the 3D drawing software, and the gear sample is machined by the method of wire cutting, and compared with the 3D model. The results show that the linear interpolation method is feasible to obtain the tooth profile of the inner helical micro segment, which provides a certain theoretical reference and application basis for the application of the inner helical micro segment gear in the design and manufacture of high precision transmission system and other related products.
