摘要: 针对成形磨削斜齿轮中接触线对磨削不平衡力、磨削加工效率以及导程修整的影响,根据成形磨削啮合原理求出砂轮与齿面之间的接触线,通过对接触线性质的分析,得到砂轮安装偏转角的变化对接触线的影响规律。基于加权平方和的优化方法,对影响接触线变化的砂轮参数进行了优化,并设计出模拟仿真程序,可用于对接触线的优化调整。较传统的砂轮安装偏转角经验取值法,本文优化结果更加精确可靠。Abstract: Considering the effect of contact line on grinding unbalanced force, grinding efficiency and lead modification, the contact line between grinding wheel and tooth face was drawn based on the principle of form grinding. By analyzing the nature of contact line, the impact of wheel inclination angle changing for contact line was obtained. At the same time, the inclination angle has been optimized by weighted sum-squared method, and the designed simulation program can be used to optimize adjustment of contact line. Compared with the traditional empiri-cal method to determine the inclination angle, the optimized inclination angle were more accurate and reliable.
