Description

一种带皇冠型保持架的轧机四点接触球轴承
技术领域
本发明涉及一种轧机四点接触球轴承，更具体来说涉及球轴承技术领域。
背景技术
轧机四点接触球轴承结构由外圈、内圈、滚子和保持架组成，单列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。
轴承保持架起到引导和隔离滚子的作用，轴承在运转时滚子在内外圈的滚道上滚动，滚子的运转又驱动轴承保持架转动，从而导致滚子与保持架产生摩擦，当轴承转速较高时由于离心力的作用会产生更大的摩擦，从而降低轴承的传动效率和寿命，球轴承的承载能力差是其突出的缺点。
发明内容
本发明为解决以上的技术问题上，提供了一种轧机四点接触球轴承的保持架，解决了承载能力差等问题。
本发明的带皇冠型保持架的轧机四点接触球轴承，包括外圈、内圈、滚子和保持架；所述保持架呈皇冠状，保持架上均匀分布着圆形滚子孔；保持架外径上有一圆弧凹槽；圆形滚子孔的一侧为完整的保持架体、另一侧为齿牙；所述外圈外径两边倒圆角；外圈内孔中间有一圆弧滚子滚道，圆弧滚子滚道一侧为环形内径、另一侧为锥形内径；外圈内孔两边均倒圆角；所述内圈外径中部有一圆弧滚子滚道，内圈外径两边倒角；内圈内孔两边倒角。
本发明与现有技术相比，具有以下优点：大大减少了摩擦，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；
图2是本发明保持架的结构图；
图3是本发明外圈的结构图；
图4是本发明内圈的结构图。
具体实施方式
本发明由图1、图2、图3和图4可知：四点接触球轴承，包括外圈1、内圈2、滚子3和保持架4；所述保持架4呈皇冠状，保持架4上均匀分布着圆形滚子孔；保持架4外径上有一圆弧凹槽；圆形滚子孔的一侧为完整的保持架体、另一侧为齿牙；所述外圈1外径两边倒圆角；外圈1内孔中间有一圆弧滚子滚道，圆弧滚子滚道一侧为环形内径、另一侧为锥形内径；外圈1内孔两边均倒圆角；所述内圈2外径中部有一圆弧滚子滚道，内圈2外径两边倒角；内圈2内孔两边倒角。
一种优选实施例：以公称外径为520mm的轧机四点接触球轴承，外圈的宽度为80mm；球滚子孔的个数为12个，球滚子孔的直径是27.2mm。
