摘要

通过齿面方程精确计算齿面网格节点坐标，根据网格节点密度要求，均匀划分网格节点，对齿根过渡曲线网格进行加密处理，直接导入有限元软件生成精确的弧齿锥齿轮啮合传动的有限元模型。设计了具有不同几何传动误差的齿面，利用有限元软件进行轮齿承载接触分析，分析了不同几何传动误差的齿轮副的接触应力、承载传动误差；基于模态叠加法对弧齿锥齿轮进行振动响应分析，得到振动位移、速度、加速度。对比结果表明，在载荷200 N·m的工况下，随着几何传动误差的增大，边缘接触程度减小，承载传动误差上下幅值波动减小44%，且对应的振动位移、速度和加速度减小，有效减小了变形和振动。

Abstract

The tooth surface grid node coordinates are accurately calculated by the tooth surface equation. According to the density requirements of the grid nodes， the grid nodes are evenly divided， the tooth root transition curve mesh is encrypted， and the finite element software is directly imported to generate an accurate finite element model of the spiral bevel gear meshing transmission. Tooth surfaces with different geometric transmission errors are designed， and the loaded tooth contact analysis is performed by using finite element software，and the contact stress and loaded transmission error of gear pairs with different geometric transmission errors are analyzed. Based on the modal superposition method， the vibration response analysis of the spiral bevel gear is used to obtain the vibration displacement， velocity， acceleration. The comparison results show that under the load of 200 N·m， as the geometric transmission error increases， the degree of edge contact decreases， the fluctuation of the upper and lower amplitudes of the loaded transmission error decreases by 44%， and the corresponding vibration displacement， speed and acceleration decrease， effectively reduce deformation and vibration.
