Problems solved by technology

[0002] Because face gears can be processed by gear shaping, hobbing and grinding, and the processing technology of face gears abroad is strictly kept secret, so the processing technology has not been mastered in China. The advantages and wide application of face gear transmission have been recognized in China However, the in-depth research on face gear transmission has been severely limited due to the lack of domestic face gear processing capabilities, and the progress of face gear transmission tests and applications has been hindered. There is no systematic research on gear hobbing
The gear shaping processing method of facing gears in China is relatively deep. Both China Southern Airlines and Beihang Airlines have improved the traditional gear shaping machines and realized the gear shaping processing of face gears. And the precision is not high, and the research on the face gear hobbing technology can not only improve the face gear processing accuracy, but also improve the face gear processing efficiency, but there is no special equipment for face gear hobbing processing in China
[0003] Therefore, there is still a lack of a face gear hobbing method and a corresponding control device to process high-precision face gears. The present invention provides a set of more specific structural design methods for the development of special equipment for face gear hobbing.

Embodiment Construction

[0034] like figure 1 As shown in the figure, according to the hobbing principle of face gears, the multi-axis linkage machine tool must be able to realize the four movements of main motion, tooth division motion, vertical feeding motion and horizontal feeding motion of face gear CNC hobbing. At the same time, due to the existence of the helix angle of the hob, the axis of the hob must rotate around the surface gear section by an angle of the helix angle, such as figure 2 However, due to the limitation of the machine tool structure, the spindle tool cannot complete the rotation of a helix angle, which brings inconvenience to the processing. In order to solve this problem, the tool is not moved, and the workpiece is offset by a distance relative to the original position. Equivalently complete the rotation of the helix angle of the face gear hob, such as image 3 shown. n w Represents the rotational speed of the hob, n 2 Represents the rotational speed of the workpiece, f 1...
