The research has deepened the domestic understanding of the end face hobbing processing method, but these studies rarely mention the calculation method of cutting adjustment parameters, which is the core technology of end face hobbing processing and the basis of studying its complete set of technologies, such as tooth surface contact performance analysis technology, machine tool motion control technology, tool design and manufacturing technology, tooth measurement and error correction technology.
There are many technical theories involved in the design and manufacturing technology of face hobbing spiral bevel gear. For a long time, few people have carried out systematic research, and only a few universities have carried out relevant research in some aspects. In the early promotion of machine tools, Oricon company once published some manual adjustment cards, but it relied too much on empirical data and formulas, and the mathematical model used was very old.
With the help of these materials, Dong Xuezhu systematically studied the tooth surface formation principle of bevel gear end face hobbing and the calculation method of cutting adjustment. Xuan Jiamin studied the pre control method of meshing characteristics of Cycloid Bevel Gear and hypoid gear pair, and proposed a tool inclined semi generative machining method based on large wheel plastic forming. However, this method can only designate the tooth surface node as the contact reference point, and can not accurately control all the contact characteristic parameters such as impression length, diagonal direction of contact area, transmission error and so on.
Wang Yongzhi studied the NC machining equipment and key technologies of digital manufacturing of Klingenberg Cycloid Bevel gear, and improved the shortcomings of the existing tooth cutting adjustment algorithm using eccentric cutter head to control the contact area of Cycloid Bevel gear. Nie Shaowu studied the tooth surface design and tooth surface correction theory of Cycloid Bevel gear, established a tooth surface mismatch design method of Cycloid Bevel gear, and proposed a tooth surface correction theory based on tooth surface mismatch pre control, which provides theoretical guidance for tooth surface design and contact area correction of Cycloid Bevel gear.
Gleason and Klingenberg have their own mature theoretical basis in the design and cutting adjustment calculation of end face hobbing spiral bevel gear. The developed calculation software systems cage and kimos can well control the contact characteristic parameters of end face hobbing spiral bevel gear during cutting adjustment calculation, but their specific theoretical methods are not disclosed.
