矿山机械特定的使用条件(如井下空气潮湿、含尘、煤岩的磨蚀、井下水的化学腐蚀、岩石冒落的危险及其它矿山地质因素)往往对机器提出既复杂又相互矛盾的要求。例如,煤层厚度限制综采设备(采煤机、机械化支架和刮板运输机)的外形尺寸和重量。随着井下机械功率不断增大,这种情况决定了机器部件(传动装置、壳体、齿轮、牵引链、机械化支架的顶梁和底座、刮板运
The specific conditions of use of a mining machine, such as wet air in the well, dust, abrasion of coal and rock, chemical corrosion of downhole water, danger of rock fall and other mine geological factors, often present complex and contradictory requirements for the machine. For example, seam thickness limits the overall dimensions and weight of fully mechanized mining equipment (shearer, mechanized support, and scraper conveyors). As downhole mechanical power continues to increase, this situation determines the mechanical components (gears, housings, gears, traction chains, roof beams and mounts of mechanized supports,
