控制铰接轴间隙延长液压支架使用寿命

 介绍了几种控制液压支架铰接孔增大的措施，以避免液压支架因铰接销孔增大，而使部件受力状况恶化，导致支架过早报废。

Fitting Clearance Control of Articulated Shaft to Prolong Service Life of Hydraulic Powered Support

The paper introduced an important factor to cause a completed set hydraulic powered support and hydraulic powered supports in batches to be scrapped is the hole diameter generally increased of each articulated hole.The paper analyzed the dangers caused by the articulated hole diameter increased of the hydraulic powered support.According to the conditions,several measures to control the diameter increasing of the articulated hole in the hydraulic powered support were introduced in order to eliminate the diameter increased of the articulated hole in the hydraulic powered support.The diameter increased would cause the stress condition getting worse and would cause the hydraulic powered support to be scrapped early.Those measures could provide the references to the maintenance personnel in the industrial site.
