磨损是指彼此触摸的外表物质不断损耗的现象。机械作业中，磨损很难根绝，在一定周期内，机械的磨损量不高于设定值，就是正常磨损。刮板输送机在作业中，脉动冲击载荷会长时刻的施加在刮板链条上，使刮板链条发作疲惫损坏。刮板链周期作业，会发生循环载荷，跟着循环载荷的不断进即将发生以下问题:资料磨损严峻、杰出的资料功能逐渐失掉、资料强度不断下降、刮板链的承载功能变差。这些问题会使刮板链上发生细微的裂纹，严峻时导致刮板链条失效开裂。刮板输送机最简单损坏的就是刮板链
Wear refers to the phenomenon of continuous loss of surface materials touching each other. In mechanical operation, wear is hard to be eliminated. In a certain period, if the wear amount of the machine is not higher than the set value, it is normal wear. In the operation of scraper conveyor, pulsating impact load is applied to scraper chain for a long time, which makes scraper chain fatigue and damage. With the development of cyclic load, the following problems will occur: severe data wear, gradual loss of outstanding data function, continuous decline of data strength, and poor bearing function of scraper chain. These problems will cause fine cracks on the scraper chain, which will lead to failure and cracking of the scraper chain when it is severe. The simplest damage of scraper conveyor is scraper chain
