介绍了集圆筛与直线筛优点于一身,并克服了圆锥与直线筛各自缺陷的平动椭圆惯性振动筛。着重介绍了无传动、无精加工的双轴自同步惯性平动椭圆振动筛,并对其激振器的追随自同步原理、自同步条件和同步状态稳定条件作了简要阐述,同时介绍了激振电机自同步节能控制器。 This paper introduces the advantages of round screen and linear screen, and overcomes the translational elliptical inertial vibrating screen which overcomes the defects of cone and linear screen respectively. In this paper, the non-driven and non-finishing biaxial self-synchronous inertial oscillating oval vibrating screen is introduced emphatically. The follow-up self-synchronizing principle of the exciter is introduced. The conditions of self-synchronization and steady-state are introduced briefly. Vibration motor self-synchronization energy-saving controller.
