摘　　要：采煤机摇臂壳体是传动系统的支撑骨架,壳体强度对采煤机传动系统的可靠性影响重大,目前国内采煤机摇臂壳体抗拉和屈服强度不高,易发生质量问题。对采煤机壳体的材料、铸造工艺、壳体加工工艺等做了一系列改进并加强了过程检验,提高了摇臂壳体的机械性能。The ranging arm shell is the supporting skeleton for the shearer drive system, it has a great impact on the shearer drive system. Currently the domestic ranging arm shell ＇s tensile and yield strength are not very high, so it＇s easy to have quality problems. This paper emphasizes on improving the material, casting and processing technique, and pay more attention to process inspection, and finally improves the shell＇s mechanical properties.
