Since the late 1960s, China has carried out in-depth and systematic research on technology from theory to application. In 1972, the former Ministry of machinery industry of China listed “Research on Gleason complete technology” as a key scientific research project, and organized a number of scientific research institutions and factories to tackle Gleason technology. Among them, Professor Wu Daren, Professor Yan Zhida and Professor Chen Zhixin systematically studied the gear Whistler theory and deduced the calculation formula of the induced normal curvature of the conjugate surface, which laid a foundation for solving the calculation principle of technical tooth cutting. Subsequently, Professor Zheng Changqi of Chongqing University, Professor Zeng Tao of Central South University, Professor Wu Xutang of Xi’an Jiaotong University, Professor Dong Xuezhu of China Agricultural University and others carried out a comprehensive study on this basis, and successfully decoded the Gleason tooth cutting calculation card, revealed its theoretical basis and processing principle, and made corresponding improvement and development, The industrial and technical system of spiral bevel gear and hypoid gear has been established.
Because the local synthesis method does not consider the tooth surface characteristics far away from the reference point and the pre control of the third-order contact parameters, the gear pair may have third-order contact defects such as prismatic, fishtail contact and S-shaped transmission. Wu Xutang, Wang Xiaochun, etc. improved the local synthesis method, established a relatively complete third-order contact analysis system by using curvature tensor and movable frame method, and optimized the third-order contact parameters by using the redundant optional parameters of the machining machine tool, so as to have better compatibility in the transmission process.
For Cycloid Bevel Gear and hypoid gear, domestic scholars are relatively few. Among them, Professor dongxuezhu of China Agricultural University has studied the calculation method of gear cutting adjustment, the geometric parameter method of indexing cone and the tooth surface correction. His book “design and manufacture of Cycloid Bevel Gears and hypoid gears” has conducted a more in-depth study on the design and adjustment calculation of Cycloid Bevel Gears and hypoid gears, which has certain guiding significance for the design and processing of Cycloid Bevel Gears and hypoid gears. In addition, liuzhifeng of Northeastern University studied the tooth surface contact analysis, edge contact analysis and dynamic loading tooth surface contact analysis method based on error. Professor Zhang Wenxiang of Anhui University of science and technology studied the oil film characteristics of Cycloid Bevel Gear by using the elastohydrodynamic lubrication theory. Feng Yihan, Zou min, Li Wei, Cao Yi, etc. studied the induced normal curvature, sentinel line, tooth surface contact analysis, strength analysis, machining simulation and computer-aided design analysis system of Cycloid Bevel gear. Wang Zhiyong studied the NC machining equipment and the key technology of digital manufacturing of Cycloid Bevel Gears. Li Haitao and Wei Wenjun proposed a new method to predict the contact quality of the tooth surface and reduce the design and processing cost of the Oricon bevel gear.
