一、前言 4000KW大型双圆弧齿轮减速器在国内首次研制成功,国外的文献中尚未发现这样的先例,并且在18时连轧机组主传动上已经成功地运转了五年多的时间,目前仍然在正常地运转。该大型双圆弧齿轮减速器是在原设备的基础和各轴的位置均已固定的情况下,代替了原渐开线齿轮减速器。运转的实践充分证明了该大型双圆弧齿轮减速器远优于原渐开线齿轮减速器,事实已经完全说明了设计研究,参数选择以及双圆弧齿轮技术等方面获得了成功,并得到了国内同行的承
I. Introduction 4000KW large double arc gear reducer was successfully developed in China for the first time. No such precedent has been found in the foreign literature, and it has been successfully operated for more than five years at the main drive of the continuous rolling mill at 18:00. At present, In normal operation. The large double arc gear reducer is the original equipment in the base and the position of each axis have been fixed, instead of the original involute gear reducer. The practice proved that the large double-arc gear reducer is far superior to the original involute gear reducer, the fact has been fully demonstrated the design and research, parameter selection and double arc gear technology has been successful and obtained Domestic counterparts bearing
