NEW INTERNAL GEAR MACHINING SYSTEM, “SUPER SKIVING SYSTEM”

抄録

In recent years, the automotive industry has been demanding high-efficiency and high-precision processing of internal gears used for planetary gear devices in terms of improvement of fuel efficiency and reduction of noise. To achieve these, manufacturers are developing a skiving cutting system. However, the conventional skiving cutting system using gear shaper cutter has not come into practical use because tool life is shortened and production costs are increased. Against such a background, Mitsubishi Heavy Industries Machine Tool Co., Ltd. (MAT) has established a new process technology, “Super Skiving System” with similar accuracy to the skiving cutting while exceeding it in efficiency and tool life. This paper presents the machining technology of internal gears comprising of 3 elements, namely the new super skiving cutter with long tool life, the specialized super skiving machine and the skiving cutting simulation software.
