用质量矩平衡法进行了并联振动筛主机构四杆机构的惯性力平衡,可达到质心稳定、减小惯性力的平衡效果,进一步用水平实验法对其平衡配重的方位进行了优化设计,优化后不仅质心稳定,惯性力更小,且曲柄上的驱动扭矩峰值大幅度降低,波动更加平缓,实现了较为理想的并联运动振动筛平衡效果。 The mass moment balance method was used to balance the inertial force of the four-bar mechanism of the parallel vibrating screen mainframe, which could stabilize the centroid and reduce the balance effect of the inertia force. The horizontal experiment method was used to optimize the orientation of the counterweight. After optimization, not only the center of mass is stable, the inertial force is smaller, but also the peak value of driving torque on the crankshaft is greatly reduced and the fluctuation is more gentle, so that the ideal balance effect of the parallel kinetic vibrating screen is achieved.
