双拖动差动调速连轧机已在国内中小轧机改造方面试用,证明是有效的。但目前差速器的寿命短,不能满足生产要求。双拖动连轧机调速主传动的基本构成如图1所示。
Double drag differential speed continuous rolling mill has been in the domestic small and medium-sized mill trial, proved to be effective. However, the current short life of the differential can not meet the production requirements. The basic structure of the main drive of double-drive continuous mill speed control is shown in Fig.1.
