目前在齿轮制齿工艺中,滚齿加工仍占着很大的比重,而且是应用最广泛、最主要的切齿方法。据估计,全世界约有75％的圆柱齿轮用滚齿法加工的。几个主要工业国家的滾齿机的拥有量约占其齿轮加工机床的1/2以上;而它与揷齿机的拥有量之比又大于1/2。多年来如何提高滾齿效率,降低滾齿成本,就一直成为各国齿轮研究工作者的努力方向。下面为滾齿机动时间(T)的计算式:
At present gear hobbing process, hobbing still occupy a large proportion, but also the most widely used, the most important method of gear cutting. It is estimated that about 75% of the world’s spur gears are hobbed. Gear hobbing machines in some of the major industrialized countries account for more than a half of their gear-processing machine tools; and the ratio of their ownership to gear machines is greater than one-half. How to improve the hobbing efficiency and reduce the hobbing cost over the years has always been the direction of the researchers in all countries. The following is the hobbing motor time (T) of the formula:
