Abstract
The invention relates to a method for integrally and dynamically balancing a cantilever rotor with an impeller. By the design of a pneumatic driving device, a dynamic balance tool, a stator support and an air pressure control device, the dynamic balance tool is mounted by simulating a mounting mode of a rotor on an engine, a vibration value transmitted by a mounting supporting point of the rotor on the engine is really measured, a high-pressure air source is led in through the pneumatic driving device, and driving accuracy and stability are improved. The influence of uncertain factors such as belt transmission elasticity unstable tension and irregular change of dynamic balance magnitude caused by repeated disassemble and assembly of the rotor is eliminated, the whole unbalance magnitude of the rotor is directly used for assembly without decomposition after meeting design requirements, and use stability and reliability of products are improved.
Description
Technical field
The present invention relates to a kind of dynamic balance method, especially a kind of cantilever rotor whole dynamic balance method with impeller.
Background technology
Cantilever rotor refers to that one end is suspended state, passes through to rotate to produce or the parts of transmission power at work.At work, because bracketed part is long, weight is large, the rotating speed of rotor is high, therefore also higher to its requirement for dynamic balance for some cantilever rotor.As in certain aeromotor, belonging to it, core engine working rotor state is cantilever position, the weight of cantilever and length are than large, maximum core engine rotor bracketed part is 203mm and 96mm with the length of support mounting portion, weight is 13.5Kg and 1.5Kg, and namely length ratio is about 2.1, weight ratio is about 9, and its dynamic balance accuracy requires high, maximum computing ballance correction requires within 10.8gmm, close to the limit of the dynamic balance accuracy grade of rotor own.At the enterprising action balance of existing belt drives dynamic balancing machine, there is the cantilevered weights of slow-speed of revolution lower rotor part, distal support reaction force multiple labile factor such as bearing clearance, belt tension in addition, irregular combined influence cannot overcome, and makes stability of equilibrium poor, poor repeatability; Again due to the restriction of core engine rotor structure, lack for belt drives position, therefore whole dynamic balance cannot be carried out, first to carry out transient equilibrium to rotatable parts, need after rotor dynamic balancing is qualified to decompose and carry out entirety assembling again, after assembling, cannot transient equilibrium be measured, facts have proved, decompose and reassemble in process, there is end tooth repetition dismounting and cause irregular transient equilibrium value at double to become large impact, cause multiple stage complete machine oscillation large and cannot use.
Summary of the invention
The object of this invention is to provide a kind of cantilever rotor whole dynamic balance method with impeller, realize the transient equilibrium of cantilever rotor.
Concrete technical scheme of the present invention is, the cantilever rotor whole dynamic balance method of described band impeller comprises the following steps:
1. prepare testpieces: cantilever rotor is assembled, comprises all rotatable parts and stator part, comprise impeller, bearing, bearing seat, bearing outside, wheel space hot plate assembly;
2. design and manufacture dynamic balancing tooling, described balance tooling is provided with installation seam, for fixing and installation cantilever rotor, described fixing when working with cantilever rotor with mounting means fix identical with mounting means, frock is also provided with stator support, for supporting stator part to ensure that dynamic component and stator part keep a safe distance when transient equilibrium;
3. design and manufacture pneumatic driving arrangement, described pneumatic drive unit comprises the exhaust apparatus be connected with high-pressure air source, described exhaust apparatus is provided with the air outlet blowing to cantilever rotor blade, air outlet is for being axially arranged symmetrically with, be at least two, between described exhaust apparatus and high-pressure air source, be provided with air pressure control device;
4. cantilever rotor is arranged on balance tooling, balance tooling is arranged on the rocker of dynamic balancing machine, pneumatic driving arrangement is installed;
5. throw off the motor on dynamic balancing machine and belt, start pneumatic driving arrangement, drive cantilever rotor to rotate, by air pressure control device regulating rotary quantum balancing rotating speed to setting, carry out conventional dynamic balance running and correct.
The air outlet direction of described pneumatic driving arrangement is perpendicular to cantilever rotor blade, and for being circular layout, quantity is identical with arm spinner blade quantity; Air pressure control device comprises solenoid valve, reduction valve, tensimeter.
The present invention is by the design of pneumatic driving arrangement, dynamic balancing tooling, stator support and air pressure control device, and dynamic balancing tooling model rotor mounting means is on the engine installed, the vibration values that true measurement rotor installation fulcrum on the engine transmits, change outer for the cantilever of relative equilibrium machine barycenter into interior barycenter, reduce cantilever to the de-stabilising effect of equilibrator test macro; By stator support, stator part and rotor element are effectively isolated, realize that core engine rotor turns, stator whole dynamic balance, do not need after transient equilibrium is qualified to decompose, retain the equilibrium state that rotor is good, use of directly installing; By pneumatic driving arrangement, high-pressure air source is introduced, the actual wind-power of model rotor drives principle of work to drive, improve and drive precision and stability, blade is driven one to one, rotor smooth running when ensureing to drive, the de-stabilising effect factor that elastic instability tension force when eliminating original belt gear with this produces.The present invention eliminates the impact of the uncertain factors such as belt gear elastic instability tension force and rotor and repeats the irregular variable effect of transient equilibrium value that dismounting causes, ensure not decompose after the overall uneven value of rotor reaches designing requirement to be directly used in installation, improve stability in use and the reliability of product.
