Description

圆柱滚子轴承用凹字型一体保持架
技术领域
本发明涉及一种轴承保持架，特别是关于一种圆柱滚子轴承用凹字型一体保持架。
背景技术
圆柱滚子轴承通常采用两种结构的保持架，一种是用直铆钉将保持架和挡盖铆合在一起；另一种保持架靠保持架梁上的凸台与挡盖铆合在一起。这两种保持架存在以下缺点：1.滚子与保持架全接触，轴承旋转时噪声大，2.兜孔较深，挡盖轻薄易变形，加工难度大。3.较为费料，材料利用率低，4.保持架梁与滚子接触面积大，摩擦磨损较大，磨损脱落的铜屑有可能进入接触区，引起轴承早期失效。
发明内容
针对现有技术中的不足，本发明旨在提供一种圆柱滚子轴承用凹字型一体保持架。
为了解决上述问题，本发明的技术解决方案是：一种圆柱滚子轴承用凹字型一体保持架，架体外径的圆周方向为凹槽型，兜孔靠近内圈方向近2/3处为直孔并带有锁量，靠近根部近1/3处为圆柱面不带锁量，内径两侧端面处带有倾角。
本发明的有益效果是：
1、保持架采用凹字型一体架体，由于结构的完全对称性，保证了保持架运转的平稳性，提高了轴承的旋转精度，并克服了传统设计中挡盖轻薄易变形的缺点；
2.材料选用黄铜，可以满足轴承在重载工况下对保持架的强度要求，凹形结构设计，在保持架外径的圆周方向加工出了凹槽，大大的减轻了保持架重量，不仅有利于轴承平稳有效的运转，降低了轴承动能损耗，而且提高了材料利用率，并降低了生产成本；
3.保持架兜孔部位采用分段式设计，靠近内圈方向近2/3处为直孔并带有锁量，靠近根部近1/3处设计成圆柱面且不带锁量，避免了滚子与保持架全接触，降低了摩擦磨损率，并避免轴承早期失效率，而且也克服了轴承低速运转时涡动，高速旋转时噪声大的缺点；
4.由于兜孔的特殊结构，使保持架储油空间更大，更有利于轴承的润滑，提高了轴承的使用寿命；
5.内径两侧端面处倾角的端面，减小保持架的应力集中，防止保持架在工作中出现疲劳断裂。
附图说明
附图1为本发明实施例的主视图；
附图2为本发明实施例的主视图的A-A视图；
附图3为本发明实施例的主视图A部局部放大图。
图中：1、架体，2、兜孔。
具体实施方式
下面结合附图对本发明做进一步地说明。
架体1材料选用黄铜加工而成，在架体1外径的圆周方向加工出了凹槽，兜孔2靠近内圈方向近2/3处为直孔并带有锁量，靠近根部近1/3处为圆柱面带锁量，内径两侧端面处带有倾角。
