摘　　要：从点啮合原理出发,对圆弧齿轮传动的运动学和动力学问题进行理论分析。论证了圆弧齿轮传动中螺旋角β、相对曲率半径ρH与圆弧齿轮齿面接触强度的关系,讨论了当螺旋角β=0时,圆弧齿轮齿面丧失接触强度和导致齿面点蚀、剥落和磨损破坏的原因;论证了圆弧齿轮的滑比Vh/V2K、Vh/V1K、螺旋角β及圆弧齿轮啮合齿面形成油膜的条件与圆弧齿轮耐磨损性能的关系,讨论了当螺旋角β=0时,发生大齿轮齿顶和小齿轮齿面严重磨损的原因。Based on the point meshing principle, the article carries out theoretical analysis of kinematics and dynamics problems of circular arc gear transmission, demonstrates the relationships among helix angle β, relative radius of curvature Ps and tooth surface contact strength of circular arc gear,discusses reasons for losing contact strength on tooth surface of circular arc gear and causing pitting, spalling and wear damage on tooth surface when helix angle β = 0, expounds the relationships among slip ratio of circular arc gear Vh/V2k, Vh/V1k, helix angle β, oil-forming condition on tooth surface of circular arc gear meshing and abrasion resisting performance of circular arc gear, discusses the reasons for severe wear appearing in addendum of bull gear and tooth surface of pinion when helix angle β = 0.
