CHE857焊条在链轮轴花键修复中的应用研究

Research on Application of CHE857 Welding Rod in Repair of Sprocket Shaft Spline

链轮轴组是矿用刮板输送机、刮板转载机的关键传动部件,由于工作时间长,传递扭矩大,使用频繁造成链轮轴组的输出花键磨损尤为严重,维修时必须按要求要进行更换,现对磨损花键表面使用CHE857焊条实施堆焊,再进行热处理淬火,经检测硬度均满足图纸技术要求。

The sprocket shaft assembly is the key transmission component of the mining scraper conveyor and the scraper transfer machine.Due to the long working time,large transmission torque and frequent use,the output spline wear of the sprocket shaft assembly is particularly serious,and must be replaced as required in maintenance.The surface of the worn spline is now surfacing with CHE857 electrode,and then heat treated and quenched.The tested hardness meets the technical requirements of the drawing.
