摘　　要：在数值计算平台上对复摆颚式破碎机特定机型破碎腔宽度的变化进行了研究。研究表明:复摆颚式破碎机工作时破碎腔宽度是在最大值和最小值之间交替变化的,其破碎比和生产能力也是变化的,成品颗粒尺寸在理论上都是不稳定的,破碎腔任一点宽度的最大值和最小值出现的位置是不同的,它随研究点位置的下移分别向右移和左移,随动颚顶端距离的增加破碎腔宽度极值单调减小。The crushing chamber width changes of the specific typed single toggle jaw crusher have been studied with numerical computation method. It shows that the width changes range from maximum to minimum with varying reduction ratio and productivity, and the production grain size is unsteady theoretically. At the same time, the width of any point of the crushing chamber has different positions for its extreme values, which moves left or right with the descending of the studied point. The extremes will have monotonic decreasing with the distance between the point and the top of movable jaw increasing.
