Transmission of point-line meshing gear

Abstract

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. It also possesses the feature of high contact strength of arc gear wheel. Thus it has greater power, lower noise, and higher efficiency to bear the weight. Not only has single point-line meshing gear (similar to single arc gear wheel) and double point-line meshing gear (similar to double arc gear wheel) been developed, but also a small tooth number of point-line meshing gear which can be only two or three. In this article, the meshing theory, design calculation, sealing graph of the parameter selection, manufacturing, 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.
