采煤机的实际生产能力、使用时的可靠性和安全性,主要取决于其割煤时的稳定性、牵引力和对底托架上的负荷。按稳定性而言,采煤机割煤滚筒位置及其转向的配合方式具有重要意义。所谓合理配合是指底托架、牵引部和截割部的相互位置及割煤滚筒转向间的配合,从而使采煤机能保持正常位置、降低牵引力並减小采煤机、输送机和支架部件上的负载。为选择回采缓斜和倾斜煤层通用采煤机的合理配合,顿涅茨煤矿机械设计院根据编制通用系列采煤机技术设计时所取得的数据,研究了8～35型标准尺寸采煤机的平衡。用EC—1020型电子数字计算机验算了采煤机在不同煤层采高,倾角和煤的截割阻力等条件下
The actual production capacity of a shearer, the reliability and safety when it is used, depends mainly on its stability when cutting coal, on its traction and on the load on the undercarriage. According to the stability, the position of coal cutter drum and its steering with the coordination of great significance. The so-called rational cooperation refers to the bottom bracket, traction and cutting the mutual position of the cutting drum and the drum between the steering, so that shearer can maintain normal position, reduce traction and reduce shearer, conveyor and bracket components On the load. In order to select the reasonable coal mining machine for gently pitching inclined and inclined coal seams, Donets Coal Mine Machinery Design Institute, based on the data obtained when compiling the universal serial shearer technology design, studied the characteristics of 8 ~ 35 standard shearer balance. With the EC-1020 electronic digital computer mining shearer mining in different seams, inclination and cutting resistance of coal and other conditions
