Dynamic Characteristic Analysis Device Of Superspeed Air Bearing Spindle

摘要

The present invention relates to a dynamic characteristic analysis device for high-speed air bearing spindle, more particularly, the nozzle is formed, and the shaft is supported by air bearings, and the motor driving the BLDC motor as controlled by 10 to rotate the shaft 20, the housing 30 and surrounding the shaft, the supply of high pressure air from the air compressor 40, In the dynamic characteristic analysis device used in the high speed air bearing spindle unit that is configured to include an air supply unit 50 is supplied to the nozzle by, is provided in the housing 30 to measure the true agree portion against radial shaft vibration (60); Amplified by removing the noise of the electric signals generated by the binary agree portion 60 and the signal processor 70 for converting an analog signal into a digital signal; And a display unit 80 for displaying data on the vibration acquired by the signal processing unit 70; Once the dynamic characteristic relates to an analysis apparatus for a high speed air bearing spindle, characterized in that is comprises a load applying device 100 that can apply a load in the horizontal direction and in the axial direction of the shaft.
