Dynamic balancer for revolved body

Abstract

The invention relates to a dynamic balancer for a revolved body, which is characterized in that the dynamic balancer comprises a speed regulation alternating current motor, a transmission disk driven by the speed regulation alternating current motor, a support component fixedly connected with the transmission disk, a revolved body, a displacement signal generator, a control box and a grinding mechanism, wherein the revolved body is positioned and clamped by the support component; the transmission disk is arranged on a workbench; the transmission disk and the support component are driven by the alternating current motor to provide a torque for the revolved body to drive the revolved body to rotate; the displacement signal generator reflects an eccentric displacement signal of the revolved body revolving at a high speed on an X-Y plane to a position that can be detected by a sensor; the eccentric displacement signal of the revolved body is detected and output to a controller by the sensor; and a control system controls the rotating speed of the revolved body, grinding position depth and feedback signal treating. The measuring and processing principle of the dynamic balancer is that a centrifugal force has an effect on the revolved body with eccentric mass in a rotating motion; with the adoption of a uniform measuring reference, a uniform processing reference and a man-machine interaction type closed-loop feedback control mode; and requirements on the measuring and processing of different accuracies can be met.

Description

technical field [0001] The invention relates to an instrument for dynamic balance testing of rotary parts or mechanisms, which can be applied to the fields of precision measurement and precision processing. Background technique [0002] Rotary components with uneven mass distribution and variable speed movement of the center of mass are common in various types of machinery. Centrifugal force is generated when this type of component moves, and the centrifugal force of the component will cause additional stress in the kinematic pair, increase friction, accelerate component wear, reduce effective bearing capacity, and shorten component life. The magnitude and direction of the centrifugal force change periodically. Under the action of the inertial force, the moving components will vibrate and generate noise, which limits the improvement of speed and work efficiency. Therefore, eliminating and reducing the centrifugal force of the rotary moving parts is the key to improving the m...
