齿顶修缘是将轮齿靠近齿顶的齿面适当加工掉一部分,以消除由于轮齿弹性变形和制造误差引起的啮合干涉,降低齿轮的啮合噪声,提高齿轮啮合性能和承载能力。许多齿轮的设计图纸要求齿顶修缘,修缘的数据取决于产品的使用工况[1-2]。某回转窑部件中有1件模数为50 mm、齿数为144、压力角为20°、齿顶圆直径为7 300 mm的标准直齿大齿圈,齿顶部的修缘需按BS2062-1标准加 Tooth top repair edge gear teeth near the tooth surface properly machined away part to eliminate due to gear tooth deformation and manufacturing errors caused by meshing interference to reduce the gear meshing noise and improve gear meshing performance and carrying capacity. Many gear designs require addendum edge repair, repair data depends on the use of the product conditions [1-2]. In a rotary kiln assembly there is a standard straight toothed ring with a modulus of 50 mm, a number of teeth of 144, a pressure angle of 20 ° and a tip circle diameter of 7 300 mm. Standard plus
