摘要
针对MG2×250/1200-WD系列采煤机在使用过程中出现的问题,通过有限元仿真技术优化摇臂壳体结构,减小应力集中现象,提高摇臂整体强度;利用温度场数值模拟技术优化减速箱传动比和空间结构,降低减速箱温度;通过优化结构和布局形式,提高过煤空间;改善开式行走轮及轴承润滑问题;提高自动化元器件的可靠性,保证工作面少人开采。通过以上优化改进,提高了整机可靠性和适应性,使其充分发挥出高产高效的能力。
Aiming at the problems occurred in the use of MG2×250/1200-WD series shearer, the shell structure of rocker arm was optimized by finite element simulation technology to reduce stress concentration and improve the overall strength of rocker arm. The temperature field numerical simulation technology was used to optimize the transmission ratio and spatial structure of the gearbox,so as to reduce the temperature of the gearbox. Through optimizing the structure and layout form, improved the coal space. Improved the lubrication problem of open travelling wheel and bearing. Improved the reliability of automatic components to ensure less mining of working face. Through the above optimization and improvement, the reliability and adaptability of the whole machine are improved, making it give full play to the capacity of high yield and high efficiency.
