Transmission of point-line meshing gear

Point-line meshing gear is a new type of meshing transmission. It possesses the merit of involute gear that can be manufactured easily and separately. And it possesses the feature of high contact strength of arc gear wheel. Thus it has greater power, lower noise, and higher efficiency to bear the weigh. It has developed not only single point - line meshing gear (similar to single arc gear wheel), double point-line meshing gear (similar to double arc gear wheel), but also little tooth number of point-line meshing gear can be only 2 or 3. In this article, the meshing theory, design calculation, the sealing graph of the parameter selection, manufacturing, the bearing ability test and the example of its applications in various places are introduced. The point-line meshing gear can be processed in common works, which process the ordinary involute gears, such as rolling tooth processing and milling tooth processing.
