摘要
针对采煤机调高机构截煤时的推进速度和推进力大小方向进行分析，给出了其主要参数的具体计算方法。这种方法克服以往用类比、估算和经验所带来的盲目性。
The paper analyzes the direction and size of driving speed and force of shearer height-regulating mechanism and offers a practical calculation of main parameters. The method can serve to overcome the blindness resulting from analogy, estimation and experiences.
