Description
Technical field
The present invention relates to a kind of rotor-support-foundation system test unit, the especially a kind of device of steam turbine, the hydraulic turbine and the three big power system rotor dynamic performance tests of large centrifugal compressor and device that the gear train assembly medium power is learned performance test of being used for.
Background technology
At present, in this three big power system of steam turbine, the hydraulic turbine and large centrifugal compressor, in the high speed and precision cogwheel gearing, all have rotor-plain bearing unit, its dynamics has decisive influence to running status, the stability of unit; In centrifugal compressor, two or three rotor-sliding bearing subsystems link together by gearing mesh, form new dynamical system.Because first three type systematic belongs to the large-sized power equipment, in operational process, even very little fault also can cause great economic loss, therefore, its dynamics research is had main meaning.
Dynamics research be unable to do without test, because the singularity of this type systematic, it is impossible carrying out various dynamic tests on actual set, and therefore, foundation can accurately reflect the test unit of its dynamic performance, has just become inevitable choice.Yet, also do not have similar testing equipment and device at present.
Summary of the invention
Characteristics such as the present invention will provide a kind of multifunctional gear rotor bearing system testing apparatus, and it has simple in structure, and is easy for installation, and array configuration is various, and the test application is wide.
Technical scheme of the present invention is achieved in that a kind of multifunctional gear rotor bearing system testing apparatus, comprises transmission shaft, quality dish or gear, bearing, bearing seat or frame.On transmission shaft, by fixedly connected quality dish of expansion set or gear, be provided with block bearing in the bearing seat at transmission shaft two ends, constitute single span rotor-bearing subsystem; At least two single span rotor-bearing subsystems are serially connected by shaft coupling, constitute multi-bearing rotor-bearing arrangement; At least two single span rotor-bearing subsystems are arranged in parallel, and substitute the quality dish with gear, and the gear installation site on each single span rotor-bearing subsystem is identical, and gear is meshing with each other, and constitute the parallel rotor-bearing arrangement of gears; At least three single span rotor-bearing subsystems are arranged in parallel, substitute the quality dish with gear, the gear of two different numbers of teeth is installed on the transmission shaft of one of them single span rotor-bearing subsystem, and the gearing mesh on adjacent with other the respectively single span rotor-bearing subsystem transmission shaft, constitute speed reduction unit or speed-increasing gear.
Transmission shaft two supports bearing is sliding bearing or rolling bearing.
The present invention adopts single span rotor-bearing subsystem as test unit, by different permutation and combination, can form multi-bearing rotor-bearing arrangement, the parallel rotor-bearing arrangement of gears, speed reduction unit or speed-increasing gear.Can be used for studying steam turbine, the hydraulic turbine dynamics, dynamic performance influence unbalance mass, on rule, the subsystem to problems such as the dynamics problem of the regularity of distribution of the influence of other subsystem unbalance response, system's critical rotary speed, high speed and precision gear train, research gearing mesh, dynamic load, twisting vibration, meshing efficiencies.Characteristics such as therefore, it has simple in structure, and is easy for installation, and array configuration is various, and the test application is wide.
