Description
Technical field
The utility model relates to the experiment table of overall machine vibration monitoring and control field, be specifically related to a kind of rotor balancing experiment table, can simulate the unbalance forced vibration of flexible rotor axle system, effectively reproduce the energy imbalance that rotating machinery produces, for the research of rotor theory of dynamic and method.
Background technology
Unbalance is the modal fault of rotating machinery, and its processing procedure is also complicated in all faults.For the balance method of flex rotor spot dynamic balance, can be summarized as modal balance method and the large class of influence coefficient method two, from counterbalance effect, although said method can be realized the desirable balance of rotor, but due to the diversity of flex rotor structure and the complicacy of actual unbalance situation, simultaneously, due to the strict restriction of the factors such as the dynamic performance of the position of cycling start number of times, rotor balancing face and vibration measuring point and number, position, axle be spot dynamic balance up to the present still still a kind of examination under theoretical direction survey process.
At present, Bently company of the U.S. has produced the dynamic balance experimental bench of single shaft, but does not connect into the balance test setting of axle system.Rotor oscillation simulated experiment platform bearing seat and base that domestic Dong great vibration measuring instrument plant produces are fixed by slide block guide rail, and sensor stand and base are fixed by monolateral screw, and positioning precision is lower, easily introduces non-power frequency fault, obscures the research to balancing fault.
For these problems, application number is that 200820028419.8 utility model patent discloses a kind of shafting dynamic balance experimental bench, comprises base, is furnished with at least two roots rotors on base, every roots rotor is supported by two oiliness bearings, and oiliness bearing is arranged in bearing seat; Between rotor and rotor directly by rigidity, do elasticity or spring coupling is connected, rotor by shaft coupling by direct motor drive; Every roots rotor is provided with and increases the weight of dish, increase the weight of to coil equal intervals and be distributed with 16 threaded holes, to simulate unbalance amount by mounting screw, every roots rotor is also furnished with two sensor support bases, be used for installing current vortex sensor, between rotor and rotor, be directly connected by rigidity, half elasticity or spring coupling; Three locating surfaces on bearing seat and sensor support base and base have corresponding mating surface, to ensure the radial fit between bearing seat and sensor support base and base, and ensure the axial restraint between bearing seat and sensor support base and base by screw.
Although this balance test platform can be simulated the unbalance forced vibration of flexible rotor axle system easily, effectively reproduces the energy imbalance that large rotating machinery produces, for the research of rotor theory of dynamic method.
But rotor connects by rigidity, half elasticity or spring coupling, and shaft coupling because material structure is inhomogeneous, foozle, alignment error, make not overlap with rotation by the principal axis of inertia of shaft coupling barycenter, shaft coupling has small bias will produce larger centrifugal intertia force, will produce larger annex dynamic pressure to bearing, thereby affect the experiment of dynamic balancing of axle system.
In simulating unbalance experiment, due to bearing seat, the impact of bearing on rotor restriction, make the current vortex sensor of sensor support seat can not obtain accurately and effectively unbalance experimental data, this just causes slewing effectively correspondingly to adjust, thereby causes slewing vibration large.
By adding screw and simulate unbalance amount on dish increasing the weight of, because screw hole location is fixed, make the unbalance amount data area of simulation narrower, the unbalance situation of model rotor in real work effectively simultaneously.
