摘　　要：链条作为链传动系统中非常重要的组成部分,在工作时销轴和套筒会发生滑动摩擦从而产生磨损,达一定程度就会导致链条伸长失效。针对失效形式,将销轴表面进行铬钒共渗处理,提高其表面硬度,进而提高销轴的耐磨性,并通过试验研究不同温度以及时间对渗层的影响,提高渗层的质量,从而大大提高链条的耐磨性能。As a very important part of the chain drive system,the sliding friction between the pin shaft and the sleeve will produce wear and tear during the operation,which will lead to the chain elongation failure to a certain extent.In view of this failure form,the surface of the pin shaft is treated with chromvanadizing to improve its surface hardness and then improve the wear resistance of the pin shaft.Through experiments,the influence of different temperatures and time on the penetration layer is studied to improve the quality of the infiltration layer,thus greatly improving the wear resistance of the chain.
