's.Each micro- section centrifugal force generated because barycenter deviates axis of rotation is all perpendicular to axis of rotation.By the synthesis of power can from
Mental and physical efforts system synthesizes a small number of concentrated forces, and direction is still perpendicular to axis.Generally, at least with being respectively acting on two cross
Two concentrated forces on section could represent original centrifugal force system.If the two concentrated forces just form couple, originally
Amount of unbalance can not be discovered and measure when rotor does not rotate；When rotation, couple just forms Horizonal Disturbing and causes rotor
Vibration.This unbalanced effect only just can be discovered and measure in the dynamic of rotation, so needing into action balance.
Static balance refers to when the quality of rotor is concentrated so that be considered as one disregards thickness perpendicular to axis of rotation very much on the other hand
The Bao Panshi of degree is not required to the balance that rotation can carry out.Its practice is to be horizontally arranged rotor, and weighting is made by gravity on one side
With lower section can be fallen to, tries the position for adjusting rotor centroid, be allowed to be located at turn around on axis.Measure unbalanced position and
After size, or directly it is removed, or is added in its symmetry direction and balance its effect with its corresponding quality,
Dynamic balancing is completed by duplicate removal or counterweight.

Structure and appearance, so the general method for not using duplicate removal adjusts dynamic balancing, it is to match to adjust the most common method of dynamic balancing at present
Weight method.Existing dynamic balance calibration machine is generally by measuring the size and angle of the vibrations that amount of unbalance generates, to determine not
The size and angle of aequum, and the size of amount of unbalance and angle are shown to by tester by software, but due to difference
Rotor amount of unbalance it is substantially different and widely different, since the dynamic balance weight for counterweight will be produced in batches, generally
A kind of dynamic balance weight of specification is all produced using in same position, for example the dynamic balance weight that certain rotor front end uses is
10g.Quality due to dynamic balance weight with match

Balance weight some is arranged in the inside of wheel hub or two side positions, and the installation site of dynamic balance weight is also circle-shaped.When using dynamic
When balancer measures progress dynamic balance running, dynamic balance running chance reflects the size of amount of unbalance with angle.
Assuming that the size of amount of unbalance is M1, the quality of dynamic balance weight is M2, and the angle of amount of unbalance is α, rotor dynamic balancing block peace
The radius of a circle of tankage is R, and the rotating speed of dynamic balance running is V, then uneven volume production circumference type dynamic balance weight mounting groove on
The centrifugal force of generation is：
F=M1V2/ R (formula one)
The direction of its centrifugal force is that the radial direction at the center of circle to the angles α can be by the centrifugation according to the principle of vector machines
Power is split, and formula is as follows：
F=F1sin β β+F2sin θ θ (formula two)
Angles of the β between F1 and F in above-mentioned formula, angles of the θ between F2 and F；
It is mounted in dynamic balance weight mounting groove with dynamic balance weight now, two is generated when rotation using dynamic balance weight

Tight knob is fixed, then two auxiliary scales 3 are adjusted to 10g respectively in the position of spill spin block 13, and the first scale 1 and second is marked
The hinge joint of ruler 2, i.e. zero graduation point are placed on the center of the circumference of dynamic balance weight mounting groove, and the direction of the second scale 2 is injustice
The direction of measurement is herein 180 °, is herein 8g, at this point, two at mobile second slide block assembly 5 to the scale of amount of unbalance
Two intersection points of the first scale 1 and dynamic balance weight mounting groove, the installation site of as two dynamic balance weights, by two dynamic balancing
Block is separately mounted to the position.
When upkeep operation does dynamic balance running, it can usually encounter the intersection point and dynamic balance weight has been installed, then need to change
The value of x or y, and then change the setting angle of dynamic balance weight, that is, change the angle of β or θ, to avoid mounted dynamic balancing
Block.
The value of x and y is typically chosen within three, when the quantity of dynamic balance weight is more, and the angle occupied is excessive,
When indicating positions adds dynamic balance weight, it can make correction that ideal effect be not achieved, at this point it is possible to rule of thumb be finely adjusted dynamic
Balance weight position first can also add multiple dynamic balance weights in the approximate angle of amount of unbalance, first preliminary to reduce amount of unbalance,
Reuse the installation site that the present invention carries out remaining dynamic balance weight.
In conclusion the present invention lead to it is simple in structure, be easy to use, can quickly determine the installation site of dynamic balance weight, substantially
The efficiency of dynamic balance running is improved ten times or more by the adjustment time for shortening dynamic balance running.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
