Description
Technical field
The present invention relates to the laboratory table of overall machine vibration monitoring and control field, be specifically related to a kind of rotor balancing experiment
Platform, it is possible to the unbalance forced vibration of simulation flexible rotor shaft system, effectively reproduces energy imbalance produced by rotating machinery, is used for
Rotor theory of dynamic and the research of method.
Background technology
Unbalance is the modal fault of rotating machinery, and its processing procedure is the most complicated in institute is faulty.For flexibility
The balance method of Dynamic Balance of Rotor, can be summarized as modal balance method and the big class of influence coefficient method two, for counterbalance effect,
Although said method can realize the desirable balance of rotor, but due to the multiformity of flex rotor structure and the unbalance situation of reality
Complexity, simultaneously as the position of cycling start number of times, rotor balancing face and vibration measuring point and number, the dynamic performance etc. of position
The strict restriction of factor, process is surveyed in a kind of examination under theoretical direction of axle system spot dynamic balance.
At present, Bently company of the U.S. produces the dynamic balance experimental bench of single shaft, but does not connect into the balance of axle system
Setup Experiments.The rotor oscillation simulated experiment platform bearing block that domestic Dong great vibration measurement instrument factory produces is solid by slide block guide rail with base
Fixed, sensor stand is fixed by monolateral screw with base, and positioning precision is relatively low, is readily incorporated non-power frequency fault, obscures flat
The research of weighing apparatus fault.
For these problems, the patent of invention of Application No. 200820028419.8 discloses a kind of shafting dynamic balance experiment
Platform, including base, base is disposed with at least two roots rotors, and every roots rotor is supported by two oiliness bearings, and oiliness bearing is installed
In bearing block；Directly being connected by rigidity, semi-elastic or yielding coupling between rotor with rotor, rotor passes through shaft coupling
By motor-driven；Every roots rotor is provided with and increases the weight of dish, increases the weight of 16 screwed holes are equidistantly distributed on dish, in order to by installing
Screw simulation unbalance amount, every roots rotor is also equipped with two sensor support bases, is used for installing current vortex sensor, rotor and rotor it
Between directly connected by rigidity, semi-elastic or yielding coupling；Bearing block and sensor support base and three location on base
Mask has corresponding cooperation face, to ensure the radial fit between bearing block and sensor support base and base, and is protected by screw
Axial restraint between barrier bearing block and sensor support base and base.
Although, this balance test platform can simulate the unbalance forced vibration of flexible rotor shaft system easily, effectively reproduces big
Energy imbalance produced by type rotating machinery, for the research of rotor theory of dynamic method.
But rotor is connected by rigidity, semi-elastic or yielding coupling, and shaft coupling owing to material structure is uneven,
Foozle, alignment error so that misaligned with rotation axis by the principal axis of inertia of shaft coupling barycenter, shaft coupling has small
Bias will produce bigger centrifugal intertia force, bearing will produce bigger adnexa dynamic pressure, thus affect the dynamic of axle system
Balance test.
Being simulated unbalance experiment when, impact rotor limited due to bearing block, bearing so that sensor props up
The current vortex sensor of support seat can not obtain unbalance experimental data accurately and effectively, and this results in slewing can not be effectively
Correspondingly adjust, thus cause slewing vibration big.
Simultaneously by increase the weight of on dish add screw simulate unbalance amount, owing to screw hole location is fixed so that simulation
Unbalance amount scope of data is narrower, it is impossible to the model rotor unbalance situation in real work effectively.
Summary of the invention
The present invention is to solve the rotor imbalance data that existing balance test platform obtains to be affected by experimental provision itself and
