Dynamic balancing process and device for a rotating body

摘要

Provided is a balancing device for a rotating body defining a rotation axis and including a plurality of balancing heads aligned along the rotation axis, each balancing head including, balancing masses configured to be moved at least along a movement circumference to cancel out the unbalance of the rotating body; at least one motor configured to move said balancing masses independently of each other, the balancing masses belonging to different balancing heads being reciprocally distanced along the rotation axis; and unbalance detectors including a plurality of vibration detectors configured to measure the vibrations caused by the unbalances of the rotating body.

1. A balancing device for a rotating body, said rotating body defining a rotation axis, said balancing device, comprising:
a rotating portion configured to be integrally connected, to the said rotating body, said rotating portion, comprising
balancing masses configured to be moved relative to said rotating body along a movement circumference to cancel out said unbalances of rotating body;a plurality of motors one for each of said balancing masses configured to move said balancing masses;a plurality of electric lines, comprising electric wires and a data line, each serving one of said electric motors,
each of said motors being associated to an electronic control card, placed at each of said motors and configured to convert analogue signals received into digital signals, and associated control electronics, wherein at least some of said electric lines comprising said data line associated with said plurality of motors, said electronic control card and said control electronics are arranged in a network, so that a reduced quantity of electric wires are positioned inside said rotating portion.
