GEAR SKIVING FOR MASS PRODUCTION

抄録

In recent years, gear skiving, also known as power skiving, has been drawing increased attention as a productive and precise cutting method, especially for internal gears. However, the technical problems of gear skiving have prevented its installation in mass production lines. These problems include high frequency vibrations caused by cutting power fluctuations during the cutting process, which lead to form errors in cut gear profiles and leads, and chip packing under high-speed cutting conditions. Based on the results of newly developed kinematical analysis, these problems have been addressed by modifying cutting machine structures, providing advanced cutter designs, and adjusting cutting conditions. The present paper discusses these problems and their solutions to make gear skiving applicable to the mass production of ring gears for the automatic transmissions of middle-sized commercial vehicles. In addition, this paper discusses the prospects for gear skiving.
