摘要
从宏观特性、微观组织和加工工艺对链斗式卸煤机125mm链条的断裂原因进行了分析。结果表明：断裂的主要原因是技板孔的直线与圆弧段连接处存在裂纹和强度不够。据此提出了改进建议。
In this paper, the cause of fracture of the 125 chain of the chain-bucket coal drop is studled. by analyzing the rnacro character, micro structure and the processing technique. The result show: the rnain reason of the failure is the crack belonging to the liner part and the arch part joints. where the strength is not enough high also. Some suggestion is given based on the above analysis.
