A method that utilizes signals from an accelerometer in resonant frequency bands or high frequency bands to, in a cost-effective manner, measure wear particle penetration of lubricant and lubricant degradation, both of which greatly affect prediction of residual service life; and, using as a basis these measurements of wear particle penetration and lubricant degradation, enables accurate estimation of residual service life for rolling bearings in the early stages.

Method of predicting residual service life for rolling bearings and a device for predicting residual service life for rolling bearings

Degradation of the lubricant due to contamination of the lubricant with wear particles or moisture, which greatly affects the service life of rolling bearings, can be detected in a cost-effective manner through the use of a resonance frequency band signal or high-frequency signal of an accelerometer, and the service life of a rolling bearing can be estimated with high precision at an early stage on the basis of the detected state of the wear particles and lubricant.

Method and device for assessing residual service life of rolling bearing

A vibration information transmission apparatus for improving efficiency of field wiring of a vibration monitoring/analyzing system includes transmitters (-to n) for converting vibration information from vibration sensors (-to n) for detecting vibration of an object to be measured, into an electric signal and outputting the electric signal to a digital network (DN). The transmitters (-to n) includes in the same casing, a transducer circuit () for converting the vibration information from the vibration sensors (-to n) into an analog electric signal, an A/D conversion circuit () for converting the analog electric signal from the transducer circuit () into a digital signal, and a network interface () for outputting the digital signal from the A/D conversion circuit () to the digital network (DN).
