    Abstract: In this system an unbalancing force, as set by an unbalance load injection device (42) integrated into a work piece balancing machine (10) and its balance computer (60), is injected into an injection plane (IP) through an operating portion of the machine (10). This injected load is in effect transferred by computation to a calibrating plane of a known standard or a masterwork part loaded into and rotatably driven by the balancing machine (10). The values of the unbalancing force as generated by the unbalance injecting device (42) and by calculation into the rotating master are sensed by synchronizer and vibration pick-ups (62). Data reflective of the injected imbalance are furnished to the balance computer (60) for the calibration thereof. The principle of this self-calibration is to use a workpiece drive spindle (16) and unbalance injector device (42) to inject a predetermined load at a known angle into the master to effect master unbalance. This induced unbalance is picked up by synchronizer units (62) and used as the parameters in the calibration process of the balance compute. This allows the machine (10) to accurately determining the imbalance in other work pieces (12). Subsequently conventional unbalanced work parts processed by the calibrated machine can be balanced by the machine with a higher-level of accuracy in accordance with balancing data of the calibrated balance computer.

    Abstract: According to the inventive method for balancing a rotor, an initial unbalance measurement is taken first and a test run is then carried out with a test weight in a predetermined balancing plane in order to determine the influence coefficients. A balance weight is then calculated iteratively by approximation, in order to minimise the residual oscillations. The anticipated residual oscillations are then determined mathematically and compared with an optimisation condition. If the optimisation condition is not satisfied the problem is a two or more plane problem rather than a single plane problem. In this case, another balancing plane is established and another test run is carried out with a known test mass being applied to said other balancing plane in order to determine the corresponding influence coefficients. A set of two balance weights and the corresponding residual oscillations are then calculated iteratively for comparing with the optimisation condition. Different balancing planes are established and test runs are carried out until the optimisation condition is satisfied. The rotor is then balanced with the calculated balancing masses.

    Abstract: A method and system for balancing a rotating device (340) or rotating system (340) having a rotatable member (348) and a shaft (348) attached to the rotatable member (348), such that balancing is based on system response to simultaneous control actions to place mass at predetermined locations within the rotating system (340) or rotating device (340). Mass may be simultaneously placed at predetermined locations within the rotating system (340). A system model (346) of measured force and motion parameters may then be calculated in response to simultaneously placing (322) mass at predetermined locations within the rotating system (340), in order to determine a required correction necessary to place the rotating system (340) in a balanced state. Force may be measured at predetermined locations throughout the rotating system (340) or rotating device (340) in response to simultaneously placing (322) the mass at the predetermined locations within the rotating system (340) or rotating device (340). Motion may also be measured at predetermined locations throughout the rotating system (340) or rotating device (340) in response to simultaneously placing (322) the mass at predetermined locations within the rotating system (340) or rotating device (340). A matrix of measured force and motion parameters may be calculated based on independent perturbations of the rotating system (340). Additionally, an independence or rank criterion may be formulated to determine whether consecutive control actions are different enough from one another to excite the system in independent directions, thereby forming a model (346) that is sufficiently representative of the dynamics of said rotating system (340).

    Abstract: The invention relates to a method and a device for measuring imbalance in rotors (3) with an asymmetric mass distribution, in particular in asymmetric crankshafts. The system imbalance of the rotor (3) is counteracted by comparison with a compensation shaft (2) that rotates synchronously with the rotor (3). To measure the imbalance, the rotor (3) is connected to the compensation shaft (2) by means of a positive and non-positive coupling unit (14). The invention is characterised in that the coupling unit (14) is designed to be coupled to the standard connection elements (15) on the front face of the rotor (3). The reference angular position (11) of the compensation shaft (2) and the reference angular position (12) of the asymmetrical rotor (3) are detected separately and fed to an electronic evaluation device (13). A correction value for the lead imbalance (9) is calculated in the evaluation device (13) from the difference between the reference angular positions (11,12) and is combined with the measured values of the imbalance that have been calculated or electrically determined.
