【摘要】：基于一种改进的切片法,实现了含齿面误差时圆柱齿轮副静态传递误差的快速计算。将传递误差分离为齿轮综合变形及综合啮合误差两部分,研究了理想齿轮和含误差齿轮传递误差的变化规律。分析结果表明,理想齿轮副的传递误差与载荷和理论接触线长度相关。在相同载荷条件下,当轴向(或端面)重合度在整数附近时,传递误差波动量最小;而当斜齿轮总重合度在整数附近时,传递误差波动量最大。对有误差齿轮副,不同载荷时的啮合刚度和综合啮合误差曲线均与实际接触线长度曲线基本一致;轻载时影响传递误差的主要因素为齿轮误差,而重载时的主要影响因素为齿轮变形。研究结论可为齿轮系统传递误差及减振设计提供一定的理论指导。
[Abstract]:Based on an improved slicing method, the fast calculation of the static transfer error of cylindrical gear pair with tooth surface error is realized. The transfer error is divided into two parts: the comprehensive deformation and the meshing error of the gear, and the variation of the transmission error of the ideal gear and the gear with error is studied. The results show that the transfer error of the ideal gear pair is related to the load and the length of the theoretical contact line. Under the same load condition, when the axial (or end) coincidence degree is near the integer, the transfer error fluctuation is the smallest, and when the total coincidence degree of the helical gear is near the integer, the transfer error fluctuation is the largest. For the gear pair with errors, the meshing stiffness and the comprehensive meshing error curve under different loads are basically the same as the actual contact line length curves, and the main factors affecting the transmission error in light load are gear errors. The main influence factor of heavy load is gear deformation. The conclusion can provide some theoretical guidance for transmission error and vibration absorption design of gear system.
