As a new type gear transmission , double circular arc profile bevel gearing carries out its transmission by means of meshing between convex - concave tooth profile in both of the direction of tooth trace and the direction of tooth depth , so it has advantage of high load capacity , long service life , easy forming hydrodynamic oil film between teeth as well as high quality of running - in etc . therefore , more attention has been paid to its application and research in recent years 作为一种新型齿轮传动方式,双圆弧弧齿锥齿轮传动不论在齿线方向、还是在齿高方向,均为凸、凹齿廓相啮合,因而它比一般的弧齿锥齿轮传动的承载能力高,使用寿命长;并且在啮合过程中两齿面间容易形成润滑油膜,具有良好的跑合性能,所以对它的应用和研究日益受到人们的重视。
