摘　　要：以重合度为1~2之间的定轴渐开线直齿轮为研究对象,基于Archard磨损模型数值仿真齿面磨损的分布规律,研究齿轮中心距安装误差对齿轮啮合过程的影响,揭示中心距安装误差对齿面磨损的影响机理。结果表明:在0.1%的中心距误差下,中心距的增大会使齿轮的重合度下降,啮合区域变小,啮入点的位置远离齿根,从而减小齿面磨损。Taking fixed-axle involute spur gears with coincidence degree between 1~2 as the research objects,the distribution law of tooth surface wear was simulated numerically based on Archard wear model,the influence of gear center distance on gear meshing process was studied,and the influence mechanism of center distance on tooth surface wear was revealed.The results show that with 0.1% of the center distance error,the increase of the center distance will reduce the gear overlap,make the meshing area smaller and keep the rod position far away from the root,thus reducing the wear on the tooth surface.
