蜗轮加工,如需获得正确的齿形,严格地讲,应采用专用蜗轮滚刀在滚齿机上以展成法加工,但在一些中、小型机械厂中,因受到设备及专用刀具等条件的限制,对于一些精度较低、螺旋角不太大的蜗轮,迄今为止,仍然采用在万能铣床上以标准齿轮盘铣刀加工蜗轮的工艺。根据本人多年来在铣床上加工各种齿轮的经验,则认为在不具备万能铣床的条件下,用齿轮盘铣刀同样可以在立铣上,甚至在平铣上加工蜗轮,下面就谈谈这方面的几点体会,便中也把盘铣刀加工蜗轮的质量作一简单分析: 一、在立铣上加工蜗轮 Strictly speaking, a special worm gear hob should be used on the gear hobbing machine to develop the processing method. However, in some medium and small-sized machinery factories, due to the restriction of equipment and special tools, , For some low precision, helix angle is not too large worm, so far, still using a universal milling machine with a standard gear cutter milling process worm. According to my many years experience in processing all kinds of gears on the milling machine, it is considered that in the condition of not having a universal milling machine, it is also possible to mill a worm gear with a gear plate cutter even on a plain milling machine. In a few aspects of experience, they also disc cutter machining worm gear for a simple analysis of the quality: First, the mill on the milling process
