Title:
軸受の検出装置及び方法
Document Type and Number:
Japanese Patent JP6888083
Kind Code:
B2
Abstract:
A bearing detecting device and method. The detecting device comprises a micro vibration sensor and a processor embedded into the same part of a bearing; the processor is connected to the micro vibration sensor; the detecting device further comprises transmitting and receiving antennas, the transmitting antenna is embedded into the part where the micro vibration sensor is positioned, and the receiving antenna is provided outside the bearing. The detecting method comprises: using the micro vibration sensor embedded in the bearing to detect an acceleration signal of the bearing; carrying out Fourier transform on the acceleration signal to obtain a characteristic frequency spectrum of the bearing; and performing matching between the characteristic frequency of the bearing and known fault characteristic frequencies of the bearing to obtain fault information of the bearing. The detecting method allows a sensor to be positioned close to a bearing as possible, thereby reducing attenuation of a fault signal of the bearing.
