摘　　要：基于螺旋锥齿轮系统动力学、几何性质,提出了一种分析真实齿面螺旋锥齿轮传动误差的方法。该方法是基于ABAQUS软件,考虑了材料阻尼、转速、惯量等因素,进行了有弹性支撑的真实齿面的螺旋锥齿轮动传动误差分析。对比真实齿面(含齿面误差的齿面)啮合和纯理论齿面啮合的动传动误差,结果表明齿面误差对动传动误差的影响较大。改变齿轮的转速发现:转速越快,齿轮啮合初期传动误差值波动越大。加入弹性支撑系统后,动传动误差值变大且齿轮啮合前期波动更剧烈。通过研究,为螺旋锥齿轮系统的振动、噪音控制提供了一个重要的研究方法。A method to analyze transmission errors of spiral bevel gears with real tooth surfaces was proposed based on the spiral bevel gear system dynamics and geometric properties. The dynamic transmission errors considering material damping,rotational speed and inertia,etc. were analyzed based on the software of ABAQUS. By comparing the two kinds of dynamic transmission errors caused by actual tooth surfaces（ tooth surfaces with errors） meshing and theoretical tooth surfaces meshing,the results showed that tooth surface errors have a greater impact on the dynamic transmission errors. It was found that the faster the gears rotate,the greater the transmission error values fluctuate; adding an elastic support system,the transmission errors become larger and amplitudes fluctuate stronger. The results provided a significant way for control of vibration and noise of spiral bevel gear systems.
