双列剖分圆柱滚子轴承优化设计

Optimal Design of Double Row Split Cylindrical Roller Bearings

针对双列剖分圆柱滚子轴承套圈剖分难度大,滚子通过剖切口时会产生冲击和振动,剖分外圈易轴向错位,内圈与轴易发生相对移动的问题,提出改进措施:将两外圈设计为无挡边结构,外隔圈设计为凸形结构,外圈剖切方式设计为V形,紧固圈设计为4个,改进后的轴承能够满足使用需求。

In view of the difficulty in splitting of double row split cylindrical roller bearing rings,the impact and vibration caused by the roller passing through the cutting,the split outer ring axial misalignment,and the inner ring and shaft relative movement,the improvement measures are put forward:designing two outer rings as a ribless structure,the outer spacer ring as a convex structure,the outer ring section as a V shape,and the fastening ring as four.The improved bearings meet the use requirements.
