摘　　要：我国出版的圆弧齿轮权威著作中对圆弧齿轮传动中心距误差敏感的解释存在重大缺陷,误导了设计者。如果按照这种解释并进行数字验证的话,所谓的圆弧齿轮传动中心距误差敏感则是一个伪命题。文中根据作者对圆弧齿轮啮合原理、设计方法的重新诠释,推导出中心距误差对圆弧齿轮传动比以及压力角的影响。找出了圆弧齿轮对中心距误差敏感的真正原因,对克服圆弧齿轮的这一弊端有重要意义。In Chinese gearology circle, there is a widely accepted statement that the arc-gear mechanism is sensitive to center distance error. However the authors mathematically and logically prove that it is not true. This paper re-explain the impact of center distance on arc-gear system from the angle of arc-gear engagement, design approach, ratio and pressure angle respectively. And finally the significant reason of this sensitivity is found that is definitely meaningful to take all advantages of the arc-gear as many as possible.
