新型惯性圆锥破碎机的减振性能

Vibration Performance on Novel Inertia Cone Crushers

利用空间连杆机构设计了一种新型的更大破碎比、更小振幅的惯性圆锥破碎机。主副激振器在电机的驱动下同时旋转,产生圆锥摆动和相位相反、大小相等的惯性离心力,以平衡惯性圆锥破碎机工作工程中产生的不平衡惯性力,同时连杆将副激振器产生的惯性离心力反馈给破碎主轴,达到增大破碎力、提高破碎效果的目的。理论计算与样机试验验证了该设计的减振与增大破碎力效果。

A new type of inertia cone crusher with less vibration and more reduction ratio was designed by using a spatial linkage. When the main exciter and the secondary exciter were simultaneously driven by the motor, a pair of inertial force with opposite phase and same magnitude was generated to achieve the purpose of balancing the unbalanced inertial forces generated during working processes. The inertia force produced by the secondary exciter was fed back to the crushing shaft through the links to gain crushing forces and crushing effects. In order to verify the efficiency of the inertia cone crusher proposed herein, the crushing products and horizontal vibrations were compared with that from the most wildly used inertia cone crushers by experimental and theoretical analysis.
