摘　　要：惯性圆锥破碎机是一种高效的细碎设备。在设备稳定工作时,动锥会绕其自身的中心旋转,旋转方向与激振器转子的旋转方向相反,动锥上相应结构的设计需要考虑并利用这一效应。本文利用内行星转子—振动机体系统解释了发生这一现象的原因。分析表明动锥产生反向旋转的运动状态是由于动锥与定锥之间的摩擦力与振动力矩共同作用的结果;当动锥的相关参数与摩擦系数符合一定关系时,动锥就会沿着定锥滚动。动锥绕其自身中心旋转的角速度与激振器转子转速、动锥半径以及排料间隙大小有关。Inertial cone crusher is high-efficient crushing equipment. When the machine is working under stable condition, the moving cone will rotate in the opposite direction to the exciter about its center. This coupling effect should be taken consideration as design the moving cone. This paper explains the reason for this effect by the intemal planetary roller-vibrating frame system. Analysis shows that the opposite rotation of the moving cone is determined by the correlation of vibrating torque and the friction force between the moving cone and the fixed cone; when certain relationship between related parameters of the moving cone and friction coefficient is meted, moving cone will roll along velocity of exciter, the fixed cone. The angular velocity of the moving cone about its center relates to the angular radius of the moving cone and the discharge gap.
