Description
Technical field
The utility model relates to a kind of for the statically balanced device of rotor.
Background technology
The rotary part (as rotor, fan etc.) of motor due to structure asymmetric (as keyway, magnetic pole size deviation) and component part quality is inhomogeneous or manufacture add man-hour error (as hole drill partially or other) etc. reason, and cause rotor imbalance mechanically, will make the center of gravity of this rotor produce skew to axis, when rotation due to eccentric effect of inertia, to produce unbalanced centrifugal force or centrifugal couple, motor will produce vibration under the effect of centrifugal force.Vibrate very greatly to the harm of motor, its consumed energy, makes the Efficiency Decreasing of motor; The directly bearing of injury motor, accelerates its wearing and tearing, reduction of service life, and the serious generation that also may cause rotating shaft and the tired breach of installing component thereof, and then cause fracture, crisis personal safety; Vibration also can have influence on basis or the running with the miscellaneous equipment of electric drilling match, makes some part loosening, in addition, and because imbalance mechanically also can produce electromechanics noise.
Therefore rotor all needs to do the balance of revolving body, the existing checkout gear for electric machinery rotator balance has closed slide static balancing apparatus, rolling bearing static balancing apparatus, ball support static balancing apparatus etc. several.

2, rolling bearing static balancing apparatus:
Rotor has assembled, and whole rotor is put on the support of bearing, conducts oneself with dignity by rotor, repeatedly adjusts, and by counterweight, makes rotor static balancing reach designing requirement, and its advantage: balance quality is high is simple to operate; Shortcoming: rotor weight can not be too heavy, and before and after requiring, the main shaft diameter of placement position is consistent; Versatility is not high; Maintenance cost is large;
3, closed slide static balancing apparatus;
Large for rotor weight excursion, before and after rotating shaft, placing position diameter can be inconsistent; Using method: rotor has assembled, whole rotor is put on the support of adjusting, and conducts oneself with dignity by rotor, repeatedly adjusts, by duplicate removal or weighting procedure, make rotor static balancing reach designing requirement, its advantage: highly sensitive, simple in structure, balance quality is high, simple to operate, and versatility is high; Shortcoming: when the diameter of placement position is inconsistent before and after rotor main shaft, adjust calibration cycle long, adjust Accuracy calibration balance precision;
Existing these several bascules, based on above-mentioned shortcoming, are not suitable for the static balance requirement of big-and-middle-sized rotor.
