Description

一种球环滚子自润滑柱形三球销
技术领域
本发明涉及汽车传动轴的领域，具体涉及一种球环滚子自润滑柱形三球销。
背景技术
常规柱型三球销万向节具有传递扭矩与运动的功能，是汽车传动轴的“关节”部件；一般用于汽车等速驱动轴的移动端，使主、从动轴以等角速度运转，传递力矩，带滚针的球环或轴承可在钟形壳内的三个轨道内进行滑移，实现驱动轴在汽车运动时产生的长度变化，对于三球销万向节的性能要求较高。
现有的柱型三球销万向节的三销架轴颈与球环之间使用滚针，为保证三球销在装配时和工作中不掉针、不卡针，需在球环与滚针间涂适量润滑脂，性能要求高。而且滚针在强度较高的工作环境下易碎，也会导致三球销万向节功能降低或失效。为保证不掉针，在三销架轴颈根部设计顶住滚针的斜面和防止干涉的圆角。同时，在三销架轴颈顶端装配有滚针挡圈。上述原因导致三球销万向节加工精度要求高，制造难度大，制造成本高。
发明内容
本发明的目的在于克服现有技术存在的不足，而提供一种球环滚子自润滑柱形三球销，不仅降低了制造难度和制造成本，而且提高了三球销万向节的使用寿命。
本发明的目的是通过如下技术方案来完成的：这种球环滚子自润滑柱形三球销，主要包括三销架和套设在三销架每一销架上的球环，所述的球环的内壁上均匀开设若干润滑槽用于填充固体润滑剂，所述的三销架轴颈与球环之间通过固体润滑剂直接接触并润滑；所述的三销架轴颈上部设置挡圈槽用于安装钢丝挡圈。
作为优选的技术方案，所述的润滑槽的数量和大小可根据具体工况进行调整。
本发明的有益效果为：
1、本发明是一种自润滑三球销，装配时不需在球环与滚针间涂润滑脂；
2、不使用润滑脂、滚针、滚针挡圈，不需在三销架根部设计顶住滚针的斜面和防止干涉的圆角，简化了万向节的结构，装配方便，减轻了制造难度，降低了制造成本；
3、不使用滚针，可增大十字轴的轴径，从而增加了强度，提高了三球销万向节的使用寿命。
附图说明
图1为本发明的结构示意图。
图2为图1中I区域的局部放大图。
附图标记说明：三销架1、球环2、润滑槽2-1、钢丝挡圈3、挡圈槽3-1。
具体实施方式
下面将结合附图对本发明做详细的介绍：
实施例：如附图所示，这种球环滚子自润滑柱形三球销，主要包括三销架1和套设在三销架1每一销架上的球环2，所述的球环2的内壁上均匀开设若干润滑槽2-1用于填充固体润滑剂，所述的三销架1轴颈与球环2之间通过固体润滑剂直接接触并润滑；所述的三销架1轴颈上部设置挡圈槽3-1用于安装钢丝挡圈3。
作为优选的技术方案，所述的润滑槽2-1形状可以为圆孔或槽，其数量和大小可根据具体工况和结构进行调整。
本发明的工作原理：本发明提出在球环2的内壁上打出润滑槽2-1并填充固体润滑剂的方式，有效解决了三球销万向节滚针易碎、需在装配时使用润滑脂、制造难度大的业界难题。当球环2和三销架1轴颈表面发生运动时，产生的摩擦面间由于填充的固体润滑剂，迅速形成一层薄的润滑膜，由于其剪切强度低，滑动时，黏着的剪切将发生在膜内，原本发生在金属间的摩擦(即轴颈外壁与球环内壁)将变成固体润滑剂间的摩擦，从而在不采用滚针的情况下也能起到很好的润滑作用。另外由于省去滚针，在设计时可以增大十字轴的轴径，以提高强度，从而延长了三球销万向节的使用寿命。
可以理解的是，对本领域技术人员来说，对本发明的技术方案及发明构思加以等同替换或改变都应属于本发明所附的权利要求的保护范围。
