| 摘 要： | 采煤机的牵引部不但负担采煤机工作时的移动和非工作时的调动,而且牵引速度的大小直接影响工作机构的效率和质量,并对整机的生产率和工作性能产生很大影响。电牵引采煤机的速度调节和方向控制均由牵引电动机的控制来完成;所以研究电牵引调速原理和牵引特性有很大的意义。

| Abstract: | Haulage unit is an important component of shearer,it drives the machine in work time and it redeploy the work in other time.Haulage speed has a great effect upon the efficiency and the quality and quantity of working body,productivity and working capacity depend on haulage speed.Speed control and direction control of electrical shearer are decided by haulage motor's control.So it is important to study the speed regulation principles and the haulage properties of electrical shearer. |
