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

一种加强型圆柱滚子轴承保持架
技术领域
本发明涉及圆柱滚子轴承保持架，具体涉及一种加强型圆柱滚子轴承保持架。
背景技术
现有加强型圆柱滚子轴承，由外圈、内圈、保持架、滚动体组成。为了增强轴承的负荷能力，在设计时增加了滚动体的数量；由于滚动体的数量增加，为了保证保持架的强度，将保持架设计为实体的一体结构，兜孔采用拉削机床或线切割机床加工，装入滚动体后再进行凿印锁紧，形成组件。一体结构的缺点是，拉削或者线切割加工兜孔效率低且成本高，凿印锁紧容易造成滚动体磕碰伤及保持架开裂，导致缩短轴承整体使用寿命，提前报废。
发明内容
本发明公开一种加强型圆柱滚子轴承保持架，通过采用新的保持架结构，解决上述问题。
为实现上述目的本发明采用以下技术方案：加强型圆柱滚子轴承由外圈⑴、内圈⑵、保持架、滚动体⑶组成；所述保持架采取由保持架座⑷和保持架盖⑸两体组合结构；所述保持架座⑷和保持架盖⑸碾压铆合结合形成组件。
本发明具有以下优点：由于保持架依然设计成实体结构，可以提供与现有加强型圆柱滚子轴承保持架同等的强度；由于保持架座和保持架盖采用两体分开结构，所以可以采用镗削或钻削加工兜孔，提高生产效率和降低加工成本40%以上；由于后期不需要凿印锁紧，完全避免滚动体磕碰伤、保持架开裂，使轴承负荷能力、使用寿命完全达到设计要求。
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2是加强型圆柱滚子轴承保持架座横向解剖示意图；
图3是加强型圆柱滚子轴承保持架座轴向解剖示意图；
图4是加强型圆柱滚子轴承保持架盖横向解剖示意图；
图5是加强型圆柱滚子轴承保持架盖轴向解剖示意图。
图中标注说明：外圈1、内圈2、滚动体3、保持架座4、保持架盖5、兜孔6。
具体实施方式
如图1所示，加强型圆柱滚子轴承保持架由保持架座4（见图2、图3）和保持架盖5（见图4、图5）两部分组成，保持架座4的兜孔6采用镗削机床或钻削机床加工；滚动体3装入外圈1后，将保持架座4的兜孔6对准滚动体3后装入，再将保持架盖5安装到保持架座4上面，然后用碾压机对保持架座4和保持架盖5进行碾压铆合、结合形成外组件；最后再将内圈2装入成型的外组件内，装配成整套轴承。
