Description

轧机用长寿命新型双列圆锥滚子轴承
(一)技术领域：一种双列圆锥滚子轴承,属大型轴承。主要用于钢铁及有色冶金行业轧钢机上作支撑辊和工作辊专用轴承。属工程元件轴承类(F16C)、金属的轧制类(B21B)。
(二)背景技术：
现有冶金钢铁、有色行业轧机支撑辊或工作辊装用的双列圆锥滚子轴承，因轴承工况条件恶劣，转速高，承受的冲击载荷大，因而轴承的使用寿命较短，换辊消耗累积辅助时间长，用户为降低使用成本，要求轴承具备长寿命。
(三)发明内容：本实用新型提出的轧机用长寿命新型双列圆锥滚子轴承，其目的就是为用户提供长寿命的双列圆锥滚子轴承。提供了两种新型号的双列圆锥滚子轴承的结构要素数值。
轧机用长寿命新型双列圆锥滚子轴承，具有由内隔圈3隔开的两个单列内圈2和一个双列外圈4；内、外圈内设多个滚子1，并由保持架5支撑，其特征是：两种型号轴承的轴承内径d、轴承外径D、轴承内圈组件宽度T、轴承外圈组件宽度C、滚子直径Dw、滚子长度L、每列数量Z以及滚子半锥角度ψ取值范围分别为表1序号1－2的一种，即取值为序号1或2的数值范围。 表1
为获取双列圆锥滚子轴承的最佳效果，表1中两种型号轴承的轴承内径d、轴承外径D、轴承内圈组件宽度T、轴承外圈组件宽度C、滚子直径Dw、滚子长度L、每列数量Z以及滚子半锥角度ψ取值分别为表2中序号1－2的一种取值。即为表1中删去公差只有公称尺寸的数值。
表2
本实用新型有益效果：本轧机用长寿命新型双列圆锥滚子轴承，采用公司独创的“滚动轴承极限设计方法”，确定了上述两种型号双列圆锥轴承的结构要素数值，本设计实现了在满足设计强度及工艺加工要求条件下，设计的滚动体直径最大，长度最长，轴承的额定动载荷值最高，轴承的计算寿命最长，满足了客户的长寿命要求，降低了客户的使用成本。
