双电动机驱动直线振动三级筛分机械的工作原理图，两台规格型号相同的电动机

The working principle diagram of the dual-motor driven linear vibration three-stage screening machine. Two motors with the same specifications and models are the source of power for the motion of the vibrating body. The two motors perform synchronous reverse motion. Because the eccentric block in the motor works, the eccentricity and its mass are equal, and pass the y-y axis, the y-y axis as the axis passes through the center of mass of the vibrating screen, so the instantaneous centrifugal inertial force generated in the eccentric block In the x-x direction, the forces in all directions cancel each other, and in the y-y direction, the forces from all directions will superimpose each other to synthesize a single direction of excitation force. When the eccentric block of the exciter moves to the figure (a) and (c), the excitation force at this time is the maximum value, because the centrifugal inertial force generated on the y-axis is completely superimposed, when the eccentric block moves to the position of (b) and (d) , The excitation force at this time is the minimum value, which is 0, because the centrifugal inertial force generated on the y-axis is completely cancelled,

Double motor drive linear vibration three-stage screening machinery working principle diagram, two models of the same type of motor is the power source of vibration body motion, two electric motors do synchronous reverse motion. Because the eccentric block in the motor is equal in its mass when it is working, and through the y-y axis, as the y-y axis of the axis, through the center of the vibration screen, the transient centrifugal inertial force generated by the eccentric block is in the x-x direction. All directional forces cancel each other out, and in the direction of y-y, all directional forces are superimposed on each other, synthesizing the shock force in a single direction, and when the eccentric block of the shocker moves to the positionofs of Figure (a) and Figure (c), the vibration force is the maximum, Because the centrifugal inertial force spawned on the y axis is completely superimposed, when the eccentric block moves to the figure (b) and figure (d) positions, the momentum force at this time is the minimum, 0, because the centrifugal inertial force generated on the y axis is completely offset.

The working principle diagram of the three-stage screening machine driven by two motors with the same specification and model is the power source of the vibration body movement, and the two motors do synchronous reverse movement. Because the eccentricity of the eccentric block in the motor is equal to its mass when it works, and the Y-Y axis, as the balance axis, passes through the mass center of the vibrating screen, so the instantaneous centrifugal inertia force generated by the eccentric block will cancel each other in all directions along the x-x direction, while in the Y-Y direction, the forces from all directions will overlap each other, resulting in a single synthesis When the eccentric block of the exciter moves to the position in figure (a) and figure (c), the exciting force is the maximum value, because the centrifugal inertia force generated on the y-axis is completely superposed, when the eccentric block moves to the position in figure (b) and figure (d), the exciting force is the minimum value, which is 0, because the centrifugal inertia force generated on the y-axis is completely offset,
