Abstract

本实用新型提供一种水平式轧辊，采用辊身与喇 叭圈合为一体的结构，减少了辊身与辊颈之间的应力 集中，提高了轧辊辊颈的强度，减少了断辊率。

Description

本实用新型提供一种水平式轧辊，可直接适用在中、小型及线材轧机的粗、中轧及成品轧机上。
目前使用的普通水平式轧辊，其轴承结构采用通用的四列短圆柱滚子轴承，主要承受大的径向负荷，轴向力由非传动端的双列向心推力球轴承和传动端的单列向心推力球轴承承担，其辊身与轴承内圈的端面放置喇叭圈及密封件。使用过程中存在以下缺点：一、当轴承运转产生较大轴向力时，喇叭圈易产生位移，挤压轴承内圈使之产生松动甚至掉块，密封件易损坏，影响轴承正常接触，使轴承载荷不均匀，易磨损发热，以致破坏。二、喇叭圈与辊颈为挤压配合，拆装困难，并且加工工艺复杂，消耗量大。三、当轧制负荷增大时，辊身与辊颈过渡的圆角面处产生应力集中，易断裂，造成故障停机，影响产量。
本实用新型的目的是提供一种水平式轧辊，使用该轧辊可减少断辊率，减少故障停机次数。
本实用新型的目的是这样实现的：水平式轧辊由辊身与辊颈组成，其特征在于：辊身与喇叭圈合为一体。
由于辊身与喇叭圈合为一体，减少了辊身与辊颈过渡的圆角面的应力集中，减少了断辊率。
下面结合具体实施例对本发明作进一步详细的说明：图1是本实用新型一种水平式轧辊的结构简图。
如图1所示：轧辊由辊身（1）与辊颈（3）组成，喇叭圈（2）与辊身合为一体。由于辊身（1）与喇叭圈（2）合为一体，两者之间不以圆角面过渡，消除了喇叭圈（2）位移造成的影响。另外，辊身（1）与辊颈（3）连接部位外径尺寸增大，减少了应力集中，提高了轧辊辊颈的强度，防止断辊事故的发生。
