Abstract

To promote the engineering application of composite transmission of high speed curve face gear, which consists of a cylindrical gear and a high speed curve face gear, the analysis of tooth bending stress should be taken into consideration. High speed curve face gear pair is a new type of curve face gear pair. Combined with the principle of high speed cam and curve face gear pair transmission, it can transfer the axial/rotation composite motion and power between two intersecting shafts. Based on the gear engagement principle, the gear meshing coordinate system was established and the fundamental of the high speed composite transmission was expounded. Combined with the tooth profile equation of generating gear, the tooth surface equation of high speed curve face gear was gained. Tooth force, contact ratio and normal load distribution were calculated. Then the tooth bending stress of high speed curve face gear during the transmission was calculated and analyzed in detail. Influence of basic parameters on tooth bending stress was discussed. Finally, the simulation and measurement experiment of tooth bending stress was carried out. By the comparison analysis of simulation, experiment and theory, the correctness of tooth bending stress calculation method was verified, which has important guiding significance for the further research of high speed curve face gear of composite transmission.

复合材料传动高速曲面齿轮齿面弯曲应力分析

为促进由圆柱齿轮和高速曲线齿轮组成的高速曲线齿轮复合传动的工程应用，应考虑齿的弯曲应力分析。高速曲线面齿轮副是一种新型的曲线面齿轮副。结合高速凸轮和曲线面齿轮副传动的原理，可以在相交的两轴之间传递轴向/旋转复合运动和动力。基于齿轮啮合原理，建立了齿轮啮合坐标系，阐述了高速复合传动的基本原理。结合生成齿轮的齿形方程，得到了高速曲线面齿轮的齿面方程。计算了齿力、接触比和法向载荷分布。然后对高速曲线面齿轮在传动过程中的齿弯应力进行了详细的计算和分析。讨论了基本参数对齿面弯曲应力的影响。最后，进行了齿面弯曲应力的仿真与测量实验。通过仿真、实验和理论对比分析，验证了齿面弯曲应力计算方法的正确性，对复合传动高速曲线面齿轮的进一步研究具有重要的指导意义。
