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
作為一種新型齒輪傳動方式,雙圓弧弧齒錐齒輪傳動不論在齒線方向、還是在齒高方向,均為凸、凹齒廓相嚙合,因而它比一般的弧齒錐齒輪傳動的承載能力高,使用壽命長;並且在嚙合過程中兩齒面間容易形成潤滑油膜,具有良好的跑合性能,所以對它的應用和研究日益受到人們的重視。 -
