Abstract

In order to meet the needs of special structural gears in the development of aviation, aerospace and automobile industries, the existing gear processing methods can not meet the processing precision. If it is necessary to pay a large cost to meet the processing precision, a new Processing method hobbing processing method of spiral face gear. On the basis of a large number of previous studies, based on the differential geometry and spatial meshing principle, the tooth surface equation of the helical face gear is derived and the threedimensional model is simulated by coordinate transformation and meshing relationship; considering the assembly mode and motion of the hob and the helical face gear Relationship, the machining coordinate system is established, and the helical face gear tooth surface and meshing equation are obtained from the hob-based worm tooth surface equation and the Archimedes worm hob is designed. Finally, the conclusion is given and the research work that needs further development is proposed. Keywords-Spiral Face Gear; Hobbing Machining

螺旋面齿轮复杂齿面成形技术研究

为了满足航空、航天和汽车工业发展中对特殊结构齿轮的需要，现有的齿轮加工方法已不能满足加工精度。若要满足加工精度需要付出较大的成本，一种新的加工方法是螺旋面齿轮的滚齿加工方法。在前人大量研究的基础上，基于微分几何和空间啮合原理，推导了斜齿面齿轮的齿面方程，并通过坐标变换和啮合关系对其三维模型进行了仿真;考虑滚刀的装配方式和运动与斜齿面齿轮的关系，建立了加工坐标系，由基于滚刀的蜗轮齿面方程得到斜齿面齿轮齿面和啮合方程，设计了阿基米德蜗轮滚刀。最后，对本文的研究工作进行了总结和展望。关键词:螺旋齿轮;滚齿机加工
