In the process of gear hobbing, the machined materials and cutting conditions affect the unit cutting force of the hob, and the cutting thickness and width of the top edge and side edge of the hob are different in machining. Therefore, it can be considered that the unit cutting...
The research on gear hobbing process in foreign countries was carried out earlier. Germany and Japan began to carry out simulation research on gear hobbing process as early as the 1970s, and Russia also published articles in this regard after 1984. The research on gear hobbing process abroad is...
Gear modification is an important technology to reduce gear vibration noise and prolong its service life. Because of the variety of gears, the complexity of working conditions, and the different gear modification parameters under different working conditions, it is difficult to form a complete gear modification system. Under ideal...
With the wide application of gear measurement center in bevel gear tooth profile measurement, it is possible to reverse the adjustment parameters of spiral bevel gear cutting and correct the tooth profile error. Scholars at home and abroad have done some research in this field. T.J. krenzer proposed a...
The application of fully NC spiral bevel gear machining equipment greatly improves the machining accuracy of spiral bevel gear, and makes it possible to change the traditional matching machining process of spiral bevel gear. In order to achieve this goal, in the actual production, first, the theoretical tooth surface...
In terms of the basic theory of spiral bevel gear, the French geometer T. Olivier proposed the envelope method for solving conjugate gear and the concept of spiral bevel gear in 1820. Different from the traditional analytical principle, he used the pure geometric principle to solve the conjugate surface....
There are three companies that provide spiral bevel gear design, manufacturing, testing technology and equipment with great influence in the world, namely Gleason in the United States, Oerlikon in Switzerland and Klingelnberg in Germany. In terms of design, they have their own mature theoretical basis, and have developed corresponding...
The numerical simulation of hypoid gear tooth surface, that is, the simulation of tooth surface machining, is the basis of subsequent tooth contact analysis, stress calculation, tooth surface design and dynamic characteristic analysis. There are many mathematical models to study the tooth surface generation of circular arc involute hypoid...
The active design technology of gear tooth surface designs the shape of gear tooth surface according to the functional requirements of gear transmission. First, the meshing performance of mating gear tooth surface is preset, that is, the transmission error curve and the best contact mark, and then the gear...
Due to the inevitable machining error and heat treatment deformation, the actually processed gear tooth surface often deviates from the theoretical design tooth surface or the standard gear tooth surface, and due to the general backwardness of domestic heat treatment technology, this deviation will be larger, sometimes up to...
