我厂缺乏大型齿轮加工设备,但出于生产任务的不断增长,需要加工为数甚多的大形齿轮,一般模数达到18—28公厘,而现有设备只能加工模数8公里的齿轮。为此,我们曾试图改装了一台滚齿机,但由于滚齿机设备有限,这种拆东墙补西墙的方法,仍然不是解决根本问题的好方法。在生产任务要求 I plant the lack of large-scale gear processing equipment, but due to the growing production tasks, the need to process a large number of large gear, the general modulus of 18-28 mm, and the existing equipment can only be processed gear 8 km gear . To this end, we have attempted to retrofit a hobbing machine, but because of the limited number of gear hobbing machines, this method of dismantling the western wall is still not a good solution to the fundamental problem.
