【摘要】 文章通过对矿用牵引链扁平接链环常见失效形式进行分析,提出了接链环齿根部的应力集中及齿向载荷分布不均匀,是造成牵引链疲劳失效的主要原因。并给出了经实际检验后的改进方案,提高了牵引链的使用寿命。更多还原

【Abstract】 With the analysis on the comment failure types of the flat connecting ring for the mine haulage chain,the paper pointed that the stress concentration on the tooth root part of the connecting ring and the uneven distribution of the load along the tooth direction shall be the main causes to occur the fatigue failure of the haulage chain.After the actual inspection,the paper provided the improved plan,which had improved the service life of the haulage chain.更多还原
