Control system of spiral bevel gear machining machine tool

In view of the above problems existing in the current spiral bevel gear machining and manufacturing, a new theory and method of spiral bevel gear tooth surface machining by using NC system is proposed to realize tooth surface machining without principle error. This paper tries to realize the high-efficiency and high-precision machining of spiral bevel gear with simple machine tool and tool structure, motion relationship and control system, and greatly reduce the equipment cost. The spiral bevel gear processed and manufactured has no principle error, so the instantaneous speed ratio of gear transmission is constant, which can be used for precision transmission; The tooth profile can be actively controlled, and it is easy to obtain the ideal tooth surface contact area; Gears are interchangeable.

The successful research of the project will greatly improve the accuracy and finishing efficiency of spiral bevel gears, and significantly reduce the cost of machine tools and gear processing. The machine tools, cutting tools and processed gears studied will have strong product competitiveness and broad market prospects.
