Description
技术领域
本发明涉及一种合金铸造产品技术领域，特别是一种基于固体润滑剂的锌基合金轴承。
背景技术
自润滑轴承是通过在轴承基体上加工若干排列有序、大小适当的孔穴，再向孔穴中嵌入固体润滑材料，从而代替传统依靠油膜润滑轴承的一种新型轴承；其具有摩擦系数低、使用寿命长、便于维护以及在低速重载下耐磨性能好的优点。现有技术中的自润滑轴承中所采用的固体润滑剂在湿度较大的环境中劣化较快，使用寿命较干燥环境中严重缩短，即抗水性较差，给实际生产作业带来较多的不确定性。
锌基合金是在纯锌中加入合金元素后制成的一种高强度耐磨材料，其主要由铝元素、铜元素、硅元素、镁元素、钛元素、硼元素以及稀土元素等构成；由于合金元素的固溶强化以及第二相强化作用，使得锌基合金既提高了强度，又因为各种元素的结构不同而产生硬质特点，从而形成独特的既耐磨又亲油的特性，从而在机械工业中可以被广泛地应用，可以用于制造轴瓦、轴套、滑块以及涡轮等耐磨器件；其优点在于：可以提高机械传动零部件的使用寿命，保持机械加工的精度；可以延长机械维护的周期，提高生产效率；对润滑油的亲和性好，且导热率高、散热快、抗咬合性好。
发明内容
为了克服现有技术的不足，本发明提供了一种基于固体润滑剂的锌基合金轴承，具有较好的抗水性，且具有组装方便、机械强度高、润滑效果好的特点，满足实际使用要求。
本发明解决其技术问题所采用的技术方案是：

与现有技术相比较，本发明的有益效果是：
本发明所提供的一种基于固体润滑剂的锌基合金轴承，结合所采用的固体润滑剂可以在-20℃～80℃的条件下使用，且在潮湿环境中具有一定的抗水性；此外，本发明提供的轴承有组装方便、机械强度高、润滑效果好的特点，且摩擦系数低、使用寿命长、便于维护、在低速重载下耐磨性能好，能够满足实际使用要求。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明所述的一种基于固体润滑剂的锌基合金轴承的结构示意图。
具体实施方式
参照图1，图1是本发明一个具体实施例的结构示意图。
如图1所示，一种基于固体润滑剂的锌基合金轴承，包括自润滑轴承外圈10和自润滑轴承内圈20，所述自润滑轴承外圈10和所述自润滑轴承内圈20同轴套装设置，且所述自润滑轴承外圈10和所述自润滑轴承内圈20之间设置有自润滑轴承滚珠30，所述自润滑轴承外圈10和所述自润滑轴承内圈20的轴向两端还分别设置有第一自润滑轴承封装盖40和第二自润滑轴承封装盖50；所述自润滑轴承外圈10的内侧面设置有配合所述自润滑轴承滚珠30的外圈滚珠限位安装槽11，所述自润滑轴承内圈20的外侧面设置有配合所述自润滑轴承滚珠30的内圈滚珠限位安装槽21；所述自润滑轴承外圈10和所述自润滑轴承内圈20上均设置有若干固体润滑剂嵌入孔12，每个所述固体润滑剂嵌入孔12中均填充有固体润滑剂，所述固体润滑剂包括以下质量百分数的组分：石墨41.0～43.0%、二硫化钼1.7～1.9%、钙钠基润滑脂7.5～10.0%、和余量的黏度指数为115～125的高密度矿物基础油；若干所述固体润滑剂嵌入孔12的轴线均沿所述自润滑轴承外圈10和所述自润滑轴承内圈20的径向设置，所述自润滑轴承外圈10上的所述固体润滑剂嵌入孔12围绕所述外圈滚珠限位安装槽11设置，且所述自润滑轴承外圈10上的所述固体润滑剂嵌入孔12连接所述外圈滚珠限位安装槽11；所述自润滑轴承内圈20上的所述固体润滑剂嵌入孔12围绕所述内圈滚珠限位安装槽21设置，且所述自润滑轴承内圈20上的所述固体润滑剂嵌入孔12连接所述内圈滚珠限位安装槽21。

具体地，所述自润滑轴承外圈10的内侧面沿轴向分布设置有两组所述外圈滚珠限位安装槽11，所述自润滑轴承外圈10的内侧面在两组所述外圈滚珠限位安装槽11之间还设置有外圈滚珠限位凸起13；所述自润滑轴承内圈20的外侧面沿轴向分布设置有两组所述内圈滚珠限位安装槽21，所述自润滑轴承内圈20的外侧面在两组所述内圈滚珠限位安装槽21之间还设置有内圈滚珠限位凸起22。所述第一自润滑轴承封装盖40和所述第二自润滑轴承封装盖50均设置有滚珠限位固定支撑柱41，所述滚珠限位固定支撑柱41沿所述自润滑轴承外圈10和所述自润滑轴承内圈20的轴向设置，且所述滚珠限位固定支撑柱41设置于所述自润滑轴承外圈10和所述自润滑轴承内圈20之间。上述结构便于两组所述自润滑轴承滚珠30的安装。
以上对本发明的较佳实施进行了具体说明，当然，本发明还可以采用与上述实施方式不同的形式，熟悉本领域的技术人员在不违背本发明精神的前提下所作的等同的变换或相应的改动，都应该属于本发明的保护范围内。
