Abstract

本发明公开一种特大型推力圆锥滚子轴承保持架体，通过采用保持架的新结构解决存在的问题。本发明采用以下技术方案：特大型推力圆锥滚子轴承由轴圈⑴、滚动体⑵、保持架体、连接铆钉⑷、座圈⑹组成；其中保持架体分为保持架体上部⑶和保持架体下部⑸两部分，采用冲压钢板成型，通过连接铆钉⑷将保持架体上部⑶和保持架体下部⑸牢固结合形成一个整体。本发明具有以下优点：由于保持架采用冲压钢板加铆钉组合结构，大大降低了保持架组件的整体重量，同时克服了现有保持架结构磨损大，轴承整体寿命低的缺点；增大了保持架组件与滚动体内部的空间，给润滑剂留出更大的存储空间；通过现场实际运行，轴承整体寿命增加30%以上。

Description

特大型推力圆锥滚子轴承保持架体
技术领域
本发明涉及推力圆锥滚子轴承保持架，具体涉及一种特大型推力圆锥滚子轴承保持架体。
背景技术
现有特大型推力圆锥滚子轴承，由轴圈、滚动体、保持架、座圈组成，其中保持架是由保持架盖和保持架座合并而成，形成对滚动体的维持和引导；现有的保持架盖和保持架座都采用浇注铜合金或者锻钢、经过机加工制造而成。特大型推力圆锥滚子轴承的保持架随着轴承尺寸的增加而增加，重量的大增不仅浪费稀有金属，增加成本，而且保持架重量过大也会加大其与座圈和滚动体的磨损，导致轴承提前损坏。
发明内容
本发明公开一种特大型推力圆锥滚子轴承保持架体，通过采用保持架的新结构解决了上述问题。
为实现上述目的本发明采用以下技术方案：特大型推力圆锥滚子轴承由轴圈⑴、滚动体⑵、保持架体、连接铆钉⑷、座圈⑹组成；其中保持架体分为保持架体上部⑶和保持架体下部⑸两部分，采用冲压钢板成型，通过连接铆钉⑷将保持架体上部⑶和保持架体下部⑸牢固结合形成一个整体。
本发明具有以下优点：由于保持架采用冲压钢板加铆钉组合结构，大大降低了保持架组件的整体重量，大量节约铜、锌等稀有金属，同时降低了现有保持架结构磨损大，轴承整体寿命低的缺点；也增大了保持架组件与滚动体内部的空间，给润滑剂留出更大的存储空间，通过现场实际运行，轴承整体寿命增加30%以上。
附图说明   
下面结合附图和具体实施方式对本发明作进一步描述。
图1为特大型推力圆锥滚子轴承轴向剖视图示意图；
图2为特大型推力圆锥滚子轴承保持架体横向剖视图示意图。
图中标注说明：轴圈1、滚动体2、保持架体上部3、连接铆钉4、保持架体下部5、座圈6、兜孔7。
具体实施方式
如图1所示，特大型推力圆锥滚子轴承由轴圈1、滚动体2、保持架体、连接铆钉4、座圈6组成；其中保持架体由保持架体上部3和保持架体下部5两块冲压钢板两部分构成。组装时，先将连接铆钉4全部安装到保持架体下部5钢板上，然后将所有滚动体2装入保持架体下部5钢板上冲压形成的兜孔7内，再将保持架体上部3钢板对准连接铆钉4，最后对全部连接铆钉4进行热铆接。此时，滚动体2与保持架体已经形成组件，最后再放入轴圈1和座圈6滚道内。
