Shafting dynamic balance experimental bench

The present invention discloses a shafting dynamic balance experiment table which comprises a base and an electric motor whereon, a rotor, a coupling, a bearing base, a sensor base and a weighting disc installed on the rotor, the invention is characterized in that the bearing base and sensor base and three locating surfaces on the base frames are provided with corresponding matching surfaces in order to guarantee the radial matching among the bearing base and the sensor base and base frame, the shafting dynamic balancing experimental table can analog the unbalanced constrained oscillation of the flexible rotor shafting, and effectively reproduce the unbalanced phenomenon generated by the large-scale rotating machinery, and the invention is used for the researching of the rotor dynamic balance and the method. The rotary spped of the experiment table, the shafting hardness, the style of the electric vortex sensor and the style of the coupling are all adjustable. The experiment table has the advantages of reasonable designing, convenient and accurate locating, small and beautiful external appearance, and the invention provides an effective and convenient experiment facility for vibration testing and balance researcher.
