Description

一种轧机四列圆锥滚子双侧密封轴承
技术领域
本发明涉及一种轧机四列圆锥滚子双侧密封轴承，更具体来说涉及一种轧机上使用的圆锥滚子轴承，属于四列圆锥滚子轴承技术领域。
背景技术
四列圆锥滚子轴承结构由外圈、双滚道外圈、内隔圈、双滚道内圈、保持架、滚子和外隔圈组成，四列圆锥滚子轴承使用在各轧钢厂的轧机上，轴承工作在冲击、高温、高速、重载、润滑不良、高压水冲刷等恶劣工况条件下。轴承箱端部设计有密封件，主要是防止外界异物进入轴承中，如杂质、冷却水、氧化铁皮等。
当刚使用新密封件时，密封效果良好，但使用一段时间后，密封效果变差，此时如不及时更换密封件，则密封效果很差，再加上轴承装拆频繁影响密封等原因，在轧制过程中产生的氧化铁皮、冷却水等异物就会进入轴承中，而润滑油脂也会外泄，这样将会引起轴承的非疲劳破坏，降低轴承的使用寿命，也会增加工人经常加油脂的工作量，及油脂的使用量和排放量，造成对环境的污染。
发明内容
本发明为解决以上的技术问题上，提供了一种轧机四列圆锥滚子双侧密封轴承，解决了外界异物进入轴承以及润滑油脂外泄等问题。
本发明的一种轧机四列圆锥滚子双侧密封轴承，外圈、双滚道外圈、双滚道内圈、保持架、滚子、O形密封圈和外隔圈；外圈呈内锥环形，外圈的外径两边和内孔两边均倒圆角；双滚道外圈呈倒V环形，双滚道外圈的外径和内孔两边均倒圆角；双滚道外圈和O形密封圈之间有密封组件；密封组件呈偏U环形，U环开口指向轴承的外侧；双滚道内圈之间有密封组件，密封组件呈圆环形。内圈是由两个双滚道内圈分体安装组成的；双滚道内圈外景上有两个滚子滚道，滚子滚道中有两个圆弧槽；双滚道内圈内孔均有一段螺旋注油槽，螺旋注油槽不超出内壁；双滚道内圈内孔上的螺旋注油槽截面为半圆形。
本发明与现有技术相比，具有以下优点：大大减少了摩擦、改善了润滑条件、提高了润滑的质量、降低摩擦发热和能耗损失，从而大大提高了轴承寿命。
附图说明
图1是本发明轴承的剖面结构图；
具体实施方式
本发明由图1可知：一种轧机四列圆锥滚子双侧密封轴承，包括外圈1、双滚道外圈2、双滚道内圈3、保持架5、滚子6、O形密封圈8和外隔圈9；外圈1呈内锥环形，外圈1的外径两边和内孔两边均倒圆角；双滚道外圈2呈倒V环形，双滚道外圈2的外径和内孔两边均倒圆角；双滚道外圈2和O形密封圈8之间有密封组件4；密封组件4呈偏U环形，U环开口指向轴承的外侧；双滚道内圈3之间有密封组件7，密封组件7呈圆环形。
一种优选实施例：以公称外径为311.15mm的轧机双列圆锥滚子轴承为例：外圈的公称宽度为200mm。有了这些密封组件有利于润滑剂的洁净，避免在轧制过程中产生的氧化铁皮、冷却水等异物就会进入轴承中，这样不仅减少了摩擦同时也改善了润滑，有利于降低摩擦发热和能耗损失。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
