平面二次包络环面蜗杆传动技术研究综述

Plane double enveloping hourglass worm gearing, which is a new transmission with high intensity, high efficiency, and high life, was designed by Capital Iron and Steel Company in the early seventies. Chinese scholars and engineers researched its meshing performance and manufacturing technologies in great depth and widely, have made great achievements. However, it has not been standardized, serialized and specialized, limiting its scope of application, because of the complexities of meshing theory and process. This paper summarized the research of the plane double enveloping hourglass worm gearing from the perspectives of meshing theory and manufacturing technology, analyzed the existing problems and shortcomings, and gave the main challenges and focus direction of it in the future.
