摘要
为深入研究安装误差对双圆弧齿轮副啮合特性的影响,基于有限元法建立齿轮加载分析模型,研究啮合过程中单齿凸、凹齿廓的接触性能,对比分析安装误差对接触性能以及传动误差的影响规律。结果表明:啮合周期内,双圆弧齿轮的凹齿廓先接触且承担较大的法向接触力,但凸齿廓的啮入端接触应力最大,凸、凹齿面接触压力差与转矩成正比;安装误差对齿面接触性能影响较大,其中中心距误差容易引起齿轮分阶处应力集中,轴线平面的安装误差会引起齿面接触偏载,且对安装误差影响最大。
In order to investigate the influence of misalignment on the meshing characteristics of double circular arc gear pairs,a gear loading analysis model based on finite element method was established.The contact performance of single tooth convex and concave tooth profiles during the meshing process was studied,and the influence of misalignment on contact performance and transmission error was compared and analyzed.The research results show that during the meshing cycle,the concave tooth profile of the double circular arc gear first contacts and bears a large normal contact force,but the contact stress at the meshing end of the convex tooth profile is the highest,and the contact pressure difference between the convex and concave tooth surfaces is proportional to the torque;misalignment has a significant impact on the contact performance of the tooth surface,the center distance errors easily causes stress concentration at the gear step,and misalignments on the axis plane can cause tooth surface contact deflection,and it has the greatest impact on installation errors.
