采煤机截割部与牵引部铰接处转动异响分析

Analysis of the Abnormal Noise of Rotation at the Joint of Cutting Part and Traction Part of the Shearer

基于采煤机截割部与牵引部铰接处的结构配合情况,分析了异常声响产生的原因,并提出了一系列改进消除异常声响的措施。经实际应用验证,通过综合应用这些消异响措施,可有效消除截割部与牵引部铰接处在转动时产生的异响,这些消除异响措施的应用,一方面有助于更好地保障采煤机的安全生产,另一方面可达到进一步延长采煤机运行寿命的目的。

Based on the structure fit of shearer’s cutting part and tra ction part, the causes of abnormal noise are analyzed, and a series of measures are put forward to improve the elimination of abnormal noise. The application of these measures can effectively eliminate the abnormal noise in the hinge of cutting part and traction part.The application of these measures can effectively eliminate the abnormal noise in the joint between the cutting part and the traction part. On the one hand, the application of these measures can better ensure the safety of shearer production, on the other hand, it can further prolong the operation life of shearer.
