摘　　要：简要论述了渐开线弧齿圆柱齿轮的主要几何参数,从其齿面方程出发,分析渐开线弧齿圆柱齿轮副齿面接触线与啮合重合度。在此基础上推导出渐开线弧齿圆柱齿轮副齿面接触应力计算公式,并通过有限元分析软件比较直齿、斜齿、弧齿齿轮副齿面接触应力。与直齿、斜齿齿轮副相比弧齿齿轮副具有更低的齿面接触应力、更好的传动特性。Puts forward the geometrical parameters of the involute arc cylindrical gear.Starting from their tooth flank equations,it analyses the equations of the lines of contact and the calculation of their su-perposition degree.On this basis,it deduces the formula for calculating the contact stress of the involute arc cylindrical gear pair and compares the tooth surface contact stress of spur gear pair,skew gear pair and the involute arc cylindrical gear pair using the FE method.Compared with spur gear pair and skew gear pair,the involute arc cylindrical gear pair has lower contact strength and better transmission characteristics.
