摘要

基于空间齿轮啮合理论

建立了平行轴渐开线变厚齿轮传动的节圆锥设计模型

提出了平行轴渐开线变厚齿轮传动的几何设计方法。考虑安装误差与变形

建立了平行轴渐开线变厚齿轮啮合分析模型

研究了节锥角、载荷与安装误差对啮合特性的影响规律。结果表明:节锥角增加使接触压力减小、齿轮副传动精度降低

但啮合刚度波动更为平缓; 载荷增加使角度传递误差均值与峰峰值均增加

但对啮合刚度均值的影响不大; 安装误差中

轴线平行度安装误差对齿轮副的啮合特性影响较大

将导致齿轮副产生边缘接触

而对于相同的轴线平行度误差量

y方向的轴线平行度误差产生的边缘接触更加严重。研究结果可望为平行轴渐开线变厚齿轮传动的工业化推广提供理论依据。

Abstract

Based on spatial gearing theory

a pitch cone design model of beveloid gear transmission with parallel axes was developed

and the geometric design method of beveloid gear transmission with parallel axes was proposed. Considering the installation errors and deformation

a meshing model of beveloid gear transmission with parallel axes was developed to investigate the influences of the cone angle and load as well as installation errors on the meshing characteristics. The results show that the increasing of the cone angle can decrease the contact force and reduce the transmission precision of the gear pair

but suppress the fluctuation of meshing stiffness; the increasing of torque load can increase both the mean value and peak to peak value of transmission error

but has only small influence on the mean value of meshing stiffness. However

the installation error in axis parallelism has a strong effect on the meshing characteristics and it will cause edge contact in gear transmission. This edge contact caused by the axis parallelism installation error in y direction is more serious under the same error condition. The research results are expected to provide a theoretical basis for industrial popularization of the beveloid gear transmission with parallel axes.
