China’s research on spiral bevel gear is relatively backward. In order to change the monopoly of foreign technology, the former Ministry of machinery industry called on Chinese scholars and research institutions to systematically study Gleason processing technology, successfully realized the solution analysis, and further expanded and developed. Based on the pitch of spiral bevel gear, Professor Zeng Tao transformed the solution of spiral bevel gear machining into the solution of pitch parameters of spiral bevel gear, and successfully deduced the calculation formula in Gleason adjustment card. Professor Zheng Changqi studied the local conjugate characteristics of spiral bevel gears and put forward the theoretical formula of contact analysis of spiral bevel gears.
The deduction of the principle of gear forming, the deduction of the principle of gear forming, the analysis of the calculation results of the full tool development, the semi tool development, and the adjustment of the hypoid are roughly the same as those of Professor Wu. Aiming at the deficiency that the local synthesis method can not effectively control the second-order parameters, Professor Wang Xiaochun proposed the third-order contact analysis theory of tooth surface, so as to solve the problem of third-order contact defects of tooth surface. The results obtained still play a long-term role in the design and processing of spiral bevel gears in China.
Chinese experts and scholars studied the equal high tooth bevel gear according to the technical data attached to the machine tool imported by Chinese manufacturers from Klingeinberg company, combined with the research results of gear meshing theory and spiral bevel gear in China. Professor Dong Xuezhu of Beijing Agricultural University has systematically studied the meshing theory of cycloidal bevel gear and hypoid gear, gear milling principle, gear blank geometric design, strength calculation, gear cutting machine tool, milling tool, milling adjustment calculation method and tooth surface contact analysis.
According to the undercut limit curve of cycloidal bevel gear, Professor Zhang Wenxiang of Anhui University of technology solved the minimum number of teeth without undercutting. According to the elastohydrodynamic lubrication theory, the oil film characteristics of cycloidal bevel gear were studied. Yang Weiyin needle studied the method of machining cycloidal bevel gear with integral cutter head, and established a method to determine the radius correction of integral cutter head by iterative calculation according to the tooth length curvature relationship between meshing tooth surfaces. It provides a certain reference basis for gear structure design and optimization. Ma Junfang pre corrected the contact area of tooth surface based on kimos by exploring the deformation law of heat treatment for ouruikang profile bevel gear pair, and achieved good results. Zhang Hua analyzed the local meshing principle of gear, tooth surface contact analysis (TCA) technology and bearing tooth surface contact analysis (LTCA) technology, and analyzed the actual contact area, load, stress and strain of equal height gear design and conventional gear design under the same conditions.
Liu Zhifeng studied the frequency response characteristics of a heavy-duty equal height bevel gear in a certain operating speed and torque range, solved the dynamic transmission error in equal height bevel gear transmission by using a new joint solution method of surface integral and local finite element, and revealed the nonlinear characteristics of transmission system vibration. A new method is given for better analysis of equal height gear transmission system.
