Description

轧机主传动装置
技术领域
本实用新型涉及金属轧机的驱动装置，用于薄带连铸连轧生产线上，传递轧制扭矩。
背景技术
目前薄带连铸连轧生产线在我国还属首创。由于薄带连铸连轧是一种短流程工艺，不同于传统的热连轧机。根据扭矩大，工作辊直径小，轧辊开口度大的特点，为了保证足够大的传动轴回转直径，主传动系统中的传动轴采用十字接轴，并且是上下交错布置。以往设计的传统精轧机中的传动轴均为鼓形齿接轴，已经不能满足现在薄带的轧制要求。因此开发一种新的主传动技术，来满足现在薄带的传递扭矩要求已势在必行。
发明内容
本实用新型的目的在于提供一种采用十字接轴，且上下交错布置的新型轧机主传动装置。
本实用新型的技术解决方案是这样实现的：
一种轧机主传动装置，包括主电机、主联轴节、复合减速机和工作辊，其特征在于还包括十字万向接轴I和十字万向接轴II；所述接轴I和接轴II采用上下交错布置，且在所述接轴I和接轴II的内部安装弹簧。
与现有技术相比较，本实用新型的优点是显而易见的，主要表现在采用十字万向接轴，上下交错布置，保证了传动轴的回转直径，适应了传递大扭矩、轧辊开口度大的需要。
附图说明
本实用新型有附图2幅，其中：
图1主传动装置主视图；
图2主传动装置平面图。
在图中：1、主电机，2、主联轴节，3、复合减速机，4、十字万向接轴I，5、十字万向接轴II，6、工作辊，7、强力弹簧。
具体实施方式
如图1-图2所示的轧机主传动装置，由主联轴节、复合减速机、上、下2根十字万向接轴等组成。电动机通过主联轴节、复合减速机、万向接轴传动工作辊。其中，十字万向接轴采用上下两根接轴交错布置，这样就可以加大轴头直径，可传递较大的扭矩，使接轴的安全性大大提高。另外，由于考虑工作辊窜辊需要，在接轴内部增加强力弹簧，一方面增加窜辊空间，另一方面考虑换辊时靠弹簧的弹力作用，压紧在接轴提升装置上，保持换辊时接轴的水平。主电机1通过主联轴节2、复合减速机3、十字万向接轴4、5传动工作辊6进行轧制。十字万向接轴4、5内部安装弹簧7，在工作辊6窜辊时，由于有弹簧7的存在，保证了需要的窜辊空间。当需要换辊时，由于工作辊6撤出，十字万向接轴4、5在弹簧7的作用下，压紧在接轴提升装置上，保持换辊时接轴的水平。
