双圆弧齿轮传动是近几年来世界上发展较快的一利机械传动,由于它具有齿面承载能力高、良好的跑合性能以及工艺性比单圆弧齿好等特点,我国在冶金、石油化工、轻工等机械设备中,已破广泛采用。但由于双圆弧齿轮滚刀制造精度要求高、周期长,且生产批量不可能很大,而经使用磨损后,难以铲磨修复。为了延长双圆弧齿轮滚刀的寿命,保证轮齿的热处理要求,我厂对调质前的双圆弧齿轮,采用普通渐开线圆柱齿轮滚刀以正变位移距方法粗滚齿形,这对于模数 m 较大(m≥7mm)的双圆弧齿轮滚刀提高寿命尤为显著,经济效益较大.这种加工方法的特点是:
Double circular arc gear transmission is one of the fastest growing mechanical transmission in the world in recent years. Because of its characteristics of high load carrying capacity, good run-in performance and better technological than single-arc tooth, Petrochemical, light industry and other machinery and equipment, has been widely used broken. However, due to double arc gear hob manufacturing precision requirements, long cycle, and the production volume is not very large, and after the use of wear and tear, hard to repair shovel. In order to extend the life of dual-arc gear hob to ensure that the gear tooth heat treatment requirements, I quenched and tempered plant before the double-arc gear, the use of ordinary involute cylindrical gear hobbing to positive displacement displacement method of coarse hobbing, which For the larger modulus (m ≥ 7mm) double arc gear hob to improve life expectancy is particularly significant, greater economic benefits.This processing method is characterized by:
