At present, gear processing is still mainly gear hobbing and gear shaping. Different processing technologies have different characteristics. In actual processing, the most suitable processing technology is often selected according to the characteristics of parts; Choosing different processing technology affects or even determines the quality and level of machining. At present, there are still many problems in gear processing technology in China, which need process designers to think about and constantly put forward new methods to optimize, so as to improve the level of gear processing technology.
1. Overview
Gear hobbing process with high efficiency is generally adopted for gear parts; Compared with the gear hobbing process, although the efficiency of gear shaping process is low, its accuracy is better than that of gear hobbing. In addition, gear shaping can process internal teeth and gears close to the shaft shoulder. For example, for some long shaft gear parts, due to the limitatio
