摘　　要：采煤机截割部传动系统多采用"三相异步电机+直齿轮减速器+行星齿轮减速器"的结构,该结构具有传动链长、可靠性低、振动大、机械设备寿命短等问题。针对这些问题,设计出结构为"永磁同步电机+四级行星齿轮减速器"的传动系统。采用低速大扭矩永磁同步电机替代传统的三相异步电动机,有效减少传动环节和故障率。为提高系统的快速性与稳定性,传动系统采用基于自适应非奇异快速终端滑模控制。最后,实验验证所提出方法不仅具有较高的响应速度而且具有较强的控制精度和鲁棒性能。设计的采煤机截割部传动系统运行良好,解决了原有系统存在的问题。The transmission system of shearer cutting part mostly adopts the structure of "three-phase asynchronous motor + spur gear reducer + planetary gear reducer". The structure has the problems of long transmission chain, low reliability, large vibration, and short life of mechanical equipment. In response to these problems, a transmission system with a structure of "permanent magnet synchronous motor + four-stage planetary gear reducer" is designed.Using low-speed and large-torque permanent magnet synchronous motors to replace traditional three-phase asynchronous motors, effectively reduces the transmission links and failure rate of the transmission system. The transmission system adopts adaptive non-singular fast terminal sliding mode control to improve the speed and stability. Finally,experiments verify that the method not only has a higher response speed, but also has a strong control accuracy and robust performance.The cutting part transmission system of the shearer works well, which solves the problems of the original system.
