Background technique
One research contents of rotor dynamics refers to amount of unbalance (centrifugal force and the centrifugation generated when the rotation of determining rotor
Couple) position and size and the operation eliminated.Amount of unbalance can cause the oscillation crosswise of rotor, and make rotor by not
Necessary dynamic loading, this is unfavorable for rotor normal operation.So most of rotors should carry out dynamic balancing detection.In machine system
In making or repairing, dynamic balance calibration becomes a procedure.
Important component of the rotor as mechanical system, its amount of unbalance vibrate caused by often, will lead to equipment vibration
Dynamic, noise and mechanism collapse, especially for high-speed rotating flex rotor, the mechanical accident of generation be will be apparent from, and rotor is not
Failure caused by balancing accounts for about 60% or more of mechanical whole failures.With the development of current accurate digital control processing technology, high speed
The dynamic equilibrium problems that rotor generated during processing seriously affect its machining accuracy are particularly important, dynamic balance instrument
It can effectively ensure equipment reliability of operation and safety, good economic benefit and social benefit can be obtained, there is weight
Big practical significance.
The amount of unbalance that rotor generates when rotating is because each micro- section of mass center of rotor does not cause on axis of rotation strictly
's.Each micro- section centrifugal force generated because mass center 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 transversal with being respectively acting on two
Two concentrated forces on face could represent original centrifugal force system.If the two concentrated forces just form couple, originally not
Aequum 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 to carry out dynamic balancing.With this
Opposite static balance refers to when the quality of rotor is concentrated very much so that the thickness of disregarding for being considered as one perpendicular to axis of rotation
When thin disk, it is not required to the balance that rotation just can be carried out.Its practice is to be horizontally arranged rotor, and weighting can be hung down by gravity on one side
To lower section, tries the position for adjusting rotor centroid, be allowed to be located at turn around on axis.After measuring unbalanced position and size,
Or directly remove it, or added in its symmetry direction and its corresponding quality balances its effect, i.e., by going
Weight or counterweight complete dynamic balancing.
Duplicate removal completes dynamic balance method generally using techniques such as polishing, drilling or cuttings, since it can destroy rotor
Structure and appearance, so the method for not using duplicate removal generally adjusts dynamic balancing, adjusting the most common method of dynamic balancing at present is to match
Weight method.Existing dynamic balance calibration machine generally passes through the size and angle for the vibration that measurement 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, due to be used to counterweight dynamic balance weight to produce in batches, generally make
A kind of dynamic balance weight of specification is all produced used in same position, for example the dynamic balance weight that certain rotor front end uses is 10g.
Since the mass difference that quality and the counterweight of dynamic balance weight need is too big, so the counterweight angle that dynamic balancing machine is shown cannot function as
The setting angle of dynamic balance weight generally can only just can determine that the installation site of dynamic balance weight by test of many times, this just directly makes
At the time-consuming too long, inefficiency of dynamic balance running.

Machine rotor generally in the dynamic balance weight mounting groove of the side of rotor body and cooling fan setting circumference type, put down by the dynamic of automotive hub
Inside or two side positions of wheel hub are arranged in weighing apparatus block some, and the installation site of dynamic balance weight is also circle-shaped.When using dynamic flat
When testing machine measurement of weighing carries out dynamic balance running, dynamic balance running chance reflects the size of amount of unbalance with angle.It is false
If 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 installation
The radius of a circle of slot is R, and the revolving speed of dynamic balance running is V, then uneven volume production circumference type dynamic balance weight mounting groove on produce
Raw centrifugal force is：
F=M1V2/ R (formula one)
The direction of its centrifugal force is that the radial direction at the center of circle to the angle α can be by the centrifugal force according to the principle of vector machines
It is split, formula is as follows：
F=F1sin β+F2sin θ (formula two)
Angle of the β between F1 and F in above-mentioned formula, angle of the θ between F2 and F；
It is mounted in dynamic balance weight mounting groove with dynamic balance weight now, generates two when rotation using dynamic balance weight
Centrifugal force is as the F1 and F2 in above-mentioned formula, the formula of centrifugal force：
F1=xM2V2/ R (formula three)
F2=yM2V2/ R (formula four)
X in above-mentioned formula, y respectively represent the number of dynamic balance weight；
There is above-mentioned formula one to four that can derive：
M1·V2/ R=xM2V2/R·sinβ+y·M2·V2/ Rsin θ (formula five)
And it can be concluded that：
M1=xM2sin β+yM2sin θ (formula six)
It just can be seen that from formula six, amount of unbalance follows parallel four side between addition dynamic balance weight quality as mechanics
Shape rule, the present invention are namely based on a kind of slide block type rotor dynamic balancing correction auxiliary tools of parallelogram rule.
Use condition and method of the invention：For example, the amount of unbalance measured is 8g, angle is 180 °, existing dynamic flat
The quality of weighing apparatus block is 10g, when desired minimum amount of unbalance is when being less than 2g, so that it may use this slide block type rotor dynamic balancing school
Positive auxiliary tool.
There can be different adjusting methods for the same amount of unbalance M1, that is, x and y is allowed to take different values respectively, x and y's
Value will affect the size of β and θ angle.In order to save material, generally as M1 < 2M2, our preferred taking x and y
Value is all 1, i.e., goes to make up amount of unbalance using two dynamic balance weights, as M1 > 2M2, or need to add dynamic balance weight
When position is already installed with dynamic balance weight, then increase the value of x or y, that is, increases the quantity of dynamic balance weight.It should be noted that working as
When the quality of dynamic balance weight is a variety of, when single dynamic balance weight can not be used to eliminate amount of unbalance, this tool can also be used, only
The dynamic balance weight quality of the addition is weighed up respectively, yes or no skateboard component is adjusted to corresponding position.
In use, the first slide block assembly 4 to be adjusted to the quality position of dynamic balance weight first, i.e. then 10g is tightened elastic
Knob is fixed, then two auxiliary scales 3 are adjusted to 10g in the position of spill spin block 13 respectively, by the first scale 1 and the second scale 2
Hinge joint, i.e., the zero graduation point center that is placed on the circumference of dynamic balance weight mounting groove, the direction of the second scale 2 are amount of unbalance
Direction, be herein 180 °, be herein 8g, at this point, two first at mobile second slide block assembly 5 to the scale of amount of unbalance
Two intersection points of scale 1 and dynamic balance weight mounting groove, the installation site of as two dynamic balance weights distinguish two dynamic balance weights
Installation is in 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 x
Or the value of y, and then change the setting angle of dynamic balance weight, that is, change the angle of β or θ, to avoid mounted dynamic balance weight.
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 balancing
Block 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 present invention carries out the installation site of remaining dynamic balance weight.
In conclusion the logical structure of the present invention is simple, it is easy to use, can quickly determines 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 are also answered
It is considered as protection scope of the present invention.
