Equilibrator swing frame system for measuring bidirectional vertical vibration signals

Abstract

The invention discloses an equilibrator swing frame system for measuring bidirectional vertical vibration signals. The equilibrator swing frame system comprises an M-shaped swing frame, a safety pressing plate, a roller support and a sensor bracket. The equilibrator swing frame system is characterized in that the M-shaped swing frame is in an integrated design; elastic elements are mutually vertical; when a rotor rotates in an unbalanced amount, the elastic elements of the swing frame are forced to vibrate so that the vibration of the rotor is transferred to the two mutually vertical elastic elements; and the bidirectional vertical vibration signals are extracted by using a sensor installed on the sensor bracket, and the unbalanced amount is calculated by a holobalancing technique. The swing frame system not only can measure the bidirectional vibration signals and use the holobalancing technique to improve the balance precision, but also can be closer to the actual operating conditionof the rotor and improve the reliability of balance. The swing frame system has the advantages of simple structure, convenient assembly and disassembly, low cost and plentiful display result, and provides a new exploration direction for studying the structure of the equilibrator.

Problems solved by technology

[0006] In view of the defects or deficiencies of the existing technology, that is, it is impossible to consider the working conditions on site. The structure of the balancing machine only measures the vibration signal in one direction, which reduces the availability of signal information, and artificially measures the structural parameters of the rotor to introduce certain errors. , the purpose of the present invention is to propose a new type of balance machine pendulum system that measures two-way vertical vibration signals with simple results. Based on the holographic dynamic balance theory, the information integration function of the holographic spectrum is fully utilized in order to improve the balance of the balance machine. Balance accuracy; in addition, reducing the difference between the balance machine support condition and the field support condition is expected to reduce the difference in the balance effect of the rotor in the balance machine and machine use
