Method and apparatus for the dynamic balancing of a rotating structure
First Claim
1. A method for the dynamic balancing of a rotatable structure rotating about a longitudinal axis, by means of an apparatus including two vibration-detecting sensors, two associated balancing devices, and processing and control means adapted for processing signals output from said two vibration-detecting sensors and for controlling said balancing devices, the method including the steps of:
- arranging each vibration-detecting sensor and its associated balancing device near a checking section, the two checking sections being spaced apart along said longitudinal axis, and controlling the operation of the balancing devices on the basis of the signals of the two vibration-detecting sensors, wherein the signals of the two vibration-detecting sensors are processed together for achieving one or more combined signals, and operation of said two balancing devices is controlled on the basis of values of said one or more combined signals.

Abstract
A method and an apparatus for balancing an elongate structure (1) rotating about an axis, like a spindle (3) carrying two grinding wheels (5, 6), wherein two vibration-detecting sensors (7, 8) and associated balancing devices (9, 10) with movable masses (11-14) are arranged at two checking sections (S1, S2) spaced out along the axis of rotation. Processing and control means (20) control the balancing devices on the basis of one or more signals (VC; VC1, VC2) achieved as combination(s) of the vibrations, in module, detected by both the sensors.
