摘要
详细分析了电牵引采煤机摇臂发热的各种原因,介绍了摇臂采用的常规冷却方式;并就大功率和极薄煤层电牵引采煤机高功率密度摇臂的发热问题提出了增加强迫润滑装置、增加冷却水管组件及冷却器等方案。
The paper minutely analyzes several causes of temperature-rising for the running ranging arm of electric haulage shearers, introduces several traditional cooling ways, and finally puts forward some practical cooling proposals for lessening temperature of running ranging arms with high-power den- sity, for example, by increasing forced lubrication device, increasing the cooling pipes and cooler etc.
