Abstract
The invention relates to an adjusting method of a rotor mass center. Through adding pre-balance before a whole processing technology process, according to a result lapelled after static balance, during a lathe outer circle, a rotor is translated towards a heavy side by a certain distance, during a lathe inner circle, the rotor is translated to a light side by a certain distance, after eccentricity, a lathe tool still walks a complete circle, after single-piece processing is finished, assemblies are assembled for carrying out moving balance again, and a balance is removed at a weight removing area to enable the rotor to finally satisfy a moving balance requirement. According to the invention, statistic imbalance can be reduced to 500 mg below during a single-piece processing process, then through the moving balance after assembling of assemblies, after a small amount of reconditioning, the moving balance can be reduced to 2 gmm, a balance precision requirement is met, application in reality is realized, and a good effect is achieved.
Description
Technical field
The present invention relates to a kind of method of adjustment of barycenter, especially a kind of method of adjustment of rotor centroid.
Background technology
Rotor is parts conventional in mechanical system, and in the time that mechanical system is worked, rotor is realized the functions such as power transmission, Conversion of Energy, mechanical movement by rotation.For the higher rotor of some rotating speeds, as essence casting impeller in aero-engine, be the moving component of the core of aero-engine, this part shape complexity, balance accuracy grade require high, in the time that engine moves, working speed reach 20,000 to 30,000 turn between, rotating speed is very high, if the amount of unbalance of this part is excessive, in running, inhomogeneous to the pressure of bearing, cause vibration aggravation, the runnability on engine, safety and life-span are caused to very serious impact.Therefore the processing of rotor element, requires very high to amount of unbalance.Traditional machining process is the most of surplus of first rough turn removal, then boring, tapping, processing technology supporting clamping part; Next repaiies benchmark, fine finishining, final size and the shape need of guarantee part.After the assay was approved, load module, does dynamic balancing.For essence casting impeller, because the initial amount of unbalance of mo(u)lded piece is larger, according to method processing in the past, be not enough to amount of unbalance to drop to by rubbing down in duplicate removal district the 2mg of requirement, and do not allow to adopt the method for punching on web to remove amount of unbalance based on security consideration yet, cannot ensure part requirement for dynamic balance.
Summary of the invention
The object of this invention is to provide a kind of method of adjustment of rotor centroid, can ensure the laggard action balance of rotor assembling time, in duplicate removal district, rubbing down just can make amount of unbalance drop to 2mg, to meet the requirement for dynamic balance of rotor when the high speed rotating.
Technical scheme of the present invention is, rotor, after casting completes, increases pre-equilibration, record the good amount of unbalance of mark before rough turn, half finish turning of whole machining process and finish turning, in postorder operation, by rotor outer circle centering, then according to the result of mark after static balance, when turning by rotor to the heavy certain distance of square translation, after eccentric, lathe tool is still walked complete circle, will remove surplus at the heavy position of rotor, surplus is removed at light position less more, thereby reduces amount of unbalance; When boring, adopt rotor to the certain distance of light direction translation; Rotor for diameter at 100-200mm, the distance of every 100mg amount of unbalance translation is 0.01mm; Single-piece work completes late assembly components and again carries out dynamic balancing, removes surplus make the final capable of satisfying dynamic equilibrium requirement of rotor in duplicate removal district.
The present invention eliminates amount of unbalance step by step by the method for centering bias, different diameters can draw according to test the distance of different translations, thereby in the process of single-piece work, the final static balance amount of rotor is reduced, then after assembled, again carry out dynamic balancing, remove small part surplus in duplicate removal district and just can meet the final requirement for dynamic balance of rotor.The present invention can reduce static-unbalance below 500mg in single-piece work process, by the dynamic balancing after assembled, after a small amount of reconditioning, computing ballance correction can be reduced to 2gmm, meets balance quality requirement again, and obtained in practice application, obtain good effect.
Brief description of the drawings
Fig. 1 is method of adjustment schematic diagram of the present invention.
Embodiment
As shown in the figure, a kind of method of adjustment of rotor centroid, rotor 1 is after casting completes, before rough turn, half finish turning of whole machining process and finish turning, increase pre-equilibration, record the good amount of unbalance of mark, in postorder operation, by rotor 1 cylindrical centering, then according to the result of mark after static balance, when turning by rotor 1 to the heavy certain distance B of square translation, eccentric after lathe tool still walk complete circle, will remove surplus at rotor 1 heavy position more, surplus is removed at light position less, thereby reduces amount of unbalance; When boring adopt by rotor 1 to the certain distance B of light direction translation; Rotor for diameter at 100-200mm, the distance B of every 100mg amount of unbalance translation is 0.01mm; Single-piece work completes late assembly components and again carries out dynamic balancing, removes surplus make the final capable of satisfying dynamic equilibrium requirement of rotor in duplicate removal district.
Claims (2)
