Introduction
Vibration caused by the rotor unbalance is one of the most critical issues in the design and maintenance of the machine. It produces dynamic forces of the state machine
And adversely affect human health. This standard is intended to provide a common framework for rotor balancing, in order to choose the appropriate method. The standard
Associate principal balance as other relevant standard usage guidelines, it is unbalanced machine classification. Thus, it can be regarded as SAC/TC53 release
A series of standards on balance a guiding standard.
In general explanation, balance and rotor imbalance is the same. This imbalance represents a specific recommendation is to make it easier to understand Required
To correct the imbalance.

4 basic principles of balance
4.1 General
Balance is a check of the rotor (part or assembly) mass distribution, and make adjustments when necessary, to ensure that the process of balancing tolerance.
Rotor imbalance may be caused by a number of factors that include materials, manufacturing and assembly, running wear, debris or operating events. important
It is to understand that even in mass production, each rotor has its own distribution imbalance.
The new rotor usually prior to installation to their operating environment, balanced by a manufacturer on a specially designed balancing machine. Modify or repair
Later, the rotor can be re-balanced on a balancing machine, or if there is no adequate facilities, the rotor can be balanced in the field (see GB/T 28785).
In the latter case, the rotor is supported on bearings and support structure for its normal use and connect it to run the drive chain.
When the rotor is in the balance or imbalance of the rotor rotary field on the centrifugal force generated. These forces can be installed in the support bearing structure
Load on the meter measured directly, or indirectly measured by measuring the vibration or bearing shaft. By these measurements, unbalance can be calculated, and through
By adding, removing, moving the rotor corrected mass balance. Depending on the task of balancing, in a correction, two or more positive school
get on.
4.2 unbalanced distribution
In fact, the imbalance is an infinite number of vectors by the unbalanced composition distribution along the rotor axis. If lumped mass model to represent the rotor,
Imbalance can be limited by sizes, different directions of imbalance vector representation, as shown in FIG.
If all unbalance vectors are corrected on their respective planes, the rotor will be perfectly balanced. In fact, these measurements
The respective imbalance is impossible, and also unnecessary. Guidance actual balancing process, the need for a more simplified representation.
