摘　　要：针对传统的齿面接触分析技术存在机床调整参数繁多、控制目标不明确和不包含传动误差优化等问题,提出以瞬时接触椭圆长半轴、接触迹线方向角及传动误差曲线交叉点纵坐标为优化目标,沿齿高方向的法曲率、沿齿长方向的法曲率以及短程挠率为控制参数,基于遗传算法的弧齿锥齿轮齿面接触区和传动误差曲线的全局优化算法具有良好的收敛性。分析了扭矩载荷对齿面接触区和传动误差的影响,用优化后的弧齿锥齿轮副有限元模型对其啮合特性进行分析,其结果验证优化方法的正确性。The traditional tooth surface contact analysis technology has many disadvantages such as numerous adjustment parameters of the machine tool, unclear control objectives and no transmission error optimization. Aiming at the above problems, a global optimization algorithm based on genetic algorithm for the contact area of the spiral bevel gear tooth surface and transmission error curve is proposed, in which taking the instantaneous contact ellipse semi-major axis, the contact trace direction angle and the ordinate of the transmission error curve intersection point as the optimization targets, the normal curvature along the tooth height direction, the normal curvature along the tooth length direction and the short-range deflection as control parameters. The optimization result can reach the expected optimization goal, and the algorithm has good convergence. In addition, the optimized finite element model of the spiral bevel gear pair is established, and its meshing characteristics are analyzed. The results again verify the correctness of the optimization method, and the influence of the torque load on the tooth surface contact area and transmission error is analyzed.
