Service behaviour and service life.Balance is exactly to improve the Mass Distribution of rotor, to ensure that gear shaft rotor revolves in its bearing
Vibration or vibration force are reduced to the technical process of allowed band because of caused by imbalance when turning.
Reducing sizing mill (FRS) is supporting equipment for high-quality wire production, and main function is the quality of lifting product,
With the amount of rolling of higher rotating speed and very little, the higher surface quality of product is obtained.Reducing sizing mill includes multiple high speed teeth
Roller box, using current dynamic balancing machine, help the imbalance of wherein gear shaft rotor being reduced in corresponding scope, but work as
Gear is assembled in use, being acted on using process axis by big temporary impact load, generation bending, permanent deformation or long
Phase works under larger unbalance loading operating mode, can all make the axle generation in gear-box more serious because fatigue effect produces permanent deformation
Imbalance problem, particularly axially vibrate larger.How to realize that spot dynamic balance turns into industry all the time in the direction of research.
Through retrieval, a large amount of patents disclose the research on spot dynamic balance, such as Chinese Patent Application No.：

Coordinate installation and pick and place, solve the problems, such as that test mass block M is difficult to placement on major axis, while it also avoid test mass block M and got rid of
Potential safety hazard.
Step 4: dynamic balance instrument 7 is again started up, by being exported after key phase 5 and the measurement additional examination weight of vibrating sensor 6
The Vibration Condition of axle 3, the rotating speed n1 of additional examination weight rear output shaft 3 is read on dynamic balance instrument 7, turns frequency amplitude alpha 1 and phase value β 1；
Step 5: turn frequency amplitude alpha, initial phase value β according to initial, test mass M, test mass M phase betas+γ, turn the and of frequency amplitude alpha 1
Phase value β 1, which is calculated, should aggravate m1 and the phase delta β that need to be adjusted, and aggravate m1 in correspondence position；Specifically initially it will turn frequency vibration width
α, initial phase value β, test mass M, test mass M phase betas+γ, turn frequency amplitude alpha 1 and phase value β 1 and input dynamic balancing to aggravate software for calculation
(row calculation procedure commonly used in the trade) is directly calculated, and weight m1 size and location, such as Fig. 4 are adjusted according to result of calculation
Shown, C points are weight m1 position.
Step 6: being again started up dynamic balance instrument 7 measures Vibration Condition, read rotating speed n2, turn frequency amplitude alpha 2 and phase value β 2,
It is confirmed whether to need static balance according to counterbalance effect, if desired, then repeat step five to six, i.e., according to the initial frequency amplitude alpha, just of turning
Beginning phase value β, m1 is aggravated, aggravates m1 phase betas+γ+Δ β, turns frequency amplitude alpha 2 and phase value β 2 continues calculating and should aggravate m2 and tune
Whole phase delta β 1, test mass size and location are adjusted according to result of calculation, then open machine measurement Vibration Condition again.Similarly, Δ β and
Δ β 1 phase directional is also identical with the direction of rotation of output shaft 3, as Fig. 4 shows.Through practical proof, using the side of the present embodiment
Method, it is that excellent dynamic balancing effect can be achieved typically once to aggravate m1, seldom occurs needing situation about aggravating twice, execute-in-place
Effect is extremely prominent.
For the present embodiment during whole regulation, the rotating speed of output shaft 3 is always consistent, i.e. rotating speed n=n1=n2, keeps away
Exempt from the vibration values to measuring and phase value impacts, ensure the Stability and veracity of measurement result.
One kind of the present embodiment subtracts sizing gearbox high-speed output shaft spot dynamic balance method, can fast and effeciently reduce defeated
