    Coupling balancing factor analysis:

      Couplings for various reasons it centroid or inertia spindle rotation axis does not coincide with its plus, when in operation will generate unbalanced centrifugal force, centrifugal force and even dynamic deflection (vibration type) phenomenon, known as rotor imbalance phenomenon, this imbalance would inevitably lead to vibration shaft, thus affecting the normal work and life of the machine. Factors causing the rotor unbalance is nothing more than a rotor body asymmetry, manufacture and installation errors, uneven and other materials in three areas. It should be resolved by calculating the increase with the mass balance in the first design phase. After the two only through the balancing machine or balancing the scene to determine the size and orientation of rotor imbalance, thus should be added to determine the size of the radius of the mass balance and orientation, add, subtract the mass balance for balance. Coupling may be corrected imbalances in the following areas 1, balance correction tolerance specification. 2, error balance correction equipment, instruments and calibration mandrel assembly. 3, after the coupling balance correction reassembled and installed two-axis errors generated when connected. 4, significant changes caused by the temperature change of the rotor imbalance. 1, the coupling body parts (half couplings, etc.) design specification to manufacturing tolerances resulting imbalance. 2, the surface of the eccentric and shaft couplings (cylindrical axis of the bore and the outer edge and coaxial) arising imbalance. 3, couplings with the gap between the parts. 4, (threaded connections, keys, shaft end plate) coupling attachment uneven distribution caused by unbalanced or asymmetrical. 5, the material of each part of the coupling uneven or unbalanced due to uneven wear.
