Description

高端百米轨梁立辊圆锥滚子轴承
技术领域
本发明涉及一种双列圆锥滚子轴承，特别是关于一种高端百米轨梁立辊圆锥滚子轴承
背景技术
百米轨梁立辊轧机对轧制的H型钢质量较高，这一要求主要取决于轴承的刚度，轴承是百米轨梁轧制生产线的关键部件，直接决定轧制H 型钢的轧制质量。轧钢时，钢坯的冲击力，使滚道与滚子处于正平接触状态；当不轧制钢材时，立辊因自重处于下沉状态，滚道与滚子处于非正平接触状态，因为轴承工作游隙及其他间隙(包括滚子与内滚道和保持架兜孔之间形成的轴向间隙、轴承装配保持架收缩后形成的径向窜动量)的存在，滚子与保持架及内圈挡边之间将产生-定冲击力，游隙与间隙越大，冲击力越大，使得保持架梁频繁产生塑性变形，并最终出现断裂，造成轴承早期失效，为了提高轴承使用寿命，必须减小双向间隙。
发明内容
为克服现有技术的缺点，本发明的目的是提供一种高端百米轨梁立辊双列圆锥滚子轴承。
本发明目的技术解决方案为：一种高端百米轨梁立辊圆锥滚子轴承，由双列圆锥滚子轴承构成，其特征在于：两个内圈小端面相抵，所述的内圈外弧面设有滚道，滚道两端设有挡边，挡边根部设有凹穴，所述的滚道内装有滚子，所述的滚子之间装有保持架，最外侧设有外圈。
本发明同现有技术相比具有以下优点：1、润滑好。2、使用寿命长。
附图说明
图1为发明的示意图。
图中：1、外圈，2、内圈，3、滚子，4、保持架。
具体实施方式
下面结合附图说明实施例:
两个内圈2小端面通过销钉连接并相抵，内圈2外弧面设有滚道，滚道两端设有挡边，加强挡边的强度，增大挡边的承载能力；挡边根部凹穴5，适当加大凹穴5，加强润滑；滚道内装有滚子3，滚子3之间装有保持架4，最外侧设有外圈1。
本发明取消传统双列圆锥滚子轴承无外隔圈，必须严格控制两外圈之间的距离，通过与轴承座的轴肩进行合理的匹配，进行游隙的自调整，精准的控制轴承的工作游隙，大大增加轴承的使用寿命；
严格控制保持架4的径向串动量，减小保持架4径向串动量，提高轴承的旋转精度。
