Description

高承载轧机四列圆柱滚子轴承
技术领域：
本实用新型涉及一种轧机用四列圆柱滚子轴承，尤其是一种高承载能力的轧机四列圆柱滚子轴承。
背景技术：
巳知的轧机用轴承FCD型由两个外国，两个内圈、两个梳形保持架和四列圆柱滚子构成。已有的轧机用四列圆柱轴承每个外国有两个外挡边、一个中挡边，故外国结构复杂，加工工艺性差、精度不高。又由于采用梳形保持架，圆柱滚子与保持架是沿轴向半边接触的，另外半边易沉头，这样承载能力差且不利于内圈的装配，特别在修磨轧辊时，带着轴承内圈卸轧辊，修磨后再安装时困难较大。
发明内容：
本实用新型针对现有技术的上述结构复杂，承载能力差且安装不便等不足，提供一种外国结构简单，并且安装方便的高承载轧机四列圆柱滚子轴承。
本实用新型的技术解决方案是：一种高承载轧机四列圆柱滚子轴承，并排设置有双外国及双内圈，在外国及内圈间设置有保持架，每个保持架上沿圆周方向均布安装有两列圆柱滚子，其特征在于：所述的保持架的尾端设置有弹簧钢丝。
所述的弹簧钢丝是卡接在保持架尾端的槽内，弹簧钢丝为环状并设有开口。
本实用新型改变轴承结构，外国没有中挡边，便于磨削加工并提高了精度。保持架采用尾端开槽用弹簧钢丝锁口的结构，并且消除了每两列滚子的间隙，圆柱滚子长度相对增加，两列滚子的端面靠着装在一个保持架内，增加了承载能力，提高了使用寿命。本轴承由于采用了如上所述的结构，与已知轴承相比，解决了不便装配和维修时滚子的沉头问题，并且提高了精度增加了轴承的承载能力和使用寿命，实践证明，本实用新型与同样尺寸的轴承相比，径向承载的动负荷提高了30％，使用寿命提高50倍，而轧机的线速度可提高60％以上，保持架加工过程简化、方便、易行。
附图说明：
图1为本实用新型的结构示意图。
图2为本实用新型外国的结构示意图。
图3为本实用新型保持架的结构示意图。
图4为本实用新型弹簧钢丝的结构示意图。
具体实施方式：
下面结合附图进一步说明本实用新型的具体实施方式。
如图1~4所示，一种高承载轧机四列圆柱滚子轴承，并排设置有双外国1及双内圈2，在外国1及内圈2间设置有保持架6，每个保持架6上沿圆周方向均布安装有两列圆柱滚子4，所述的保持架6的尾端设置有槽，其内卡接有弹簧钢丝5。弹簧钢丝5为环状并设有开口3。在四列圆柱滚子中，每两列滚子4的端面靠着装在一个保持架6内，由于消除了每两列滚子的间隙，相同宽度的轴承滚子的长度增加了，因而增加了与内、外国的接触面积，提高了承载能力和使用寿命。每个尾端开口的保持架6装入圆柱滚子4后，封头时是将弹簧钢丝5放入保持架的开槽处锁紧。
