1、简介 随着采煤机械化及自动化的增长和生产效率的提高,电力驱动的采煤机变得越来越重要了。因为无论气动透平还是液压马达,实际上都不可能带动性能优良的采煤机,所以,不使用电子技术就不可能实现对采煤机必要的控制和调节。 2、采煤机的结构 (1)中心驱动 艾柯夫(Eickhoff)公司研制的采煤机的电机标称功率为170、200和300千瓦。使用双机驱动时,采煤机功率为340和600千瓦。各种类型采煤机的电机都是和机身结为一体的。电机轴一端伸出带动齿轮箱,另一端伸出带动液压牵引部,在双摇臂采
1. Introduction With the mechanization and automation of coal mining increasing and production efficiency increasing, electric powered shearers have become more and more important. Because neither the pneumatic turbine nor the hydraulic motor is in fact capable of driving a shearer with superior performance, it is not possible to achieve the necessary control and regulation of the shearer without the use of electronic technology. Shearer Structure (1) Center-driven Eickhoff's shearers have nominal motor powers of 170, 200 and 300 kW. Shearer power is 340 and 600 kilowatts when using dual-drive. All types of shearer motor and the fuselage is one. One end of the motor shaft extends to drive the gear box, and the other end extends out to drive the hydraulic traction part,
