GB2520322A

A process for monitoring for the presence of fretting and/or smearing with false brinelling potential in a non-rotating hearing comprises the steps of acquiring acoustic emission data emanating from the non-rotating bearing under an alternating load and comparing the acoustic emission data with a threshold indicative of fretting and/or smearing

Accelerated Bearing Life

For bearing condition monitoring the vibration signal is broadly accepted as a reliable data source When a roller hits a fault the impact energy causes the bearing to vibrate at its resonance frequency This vibration is measured using an accelerometer and is analyzed to determine the bearing condition

Machines

This paper presents an empirical study of feature extraction methods for the application of low-speed slew bearing condition monitoring The aim of the study is to find the proper features that represent the degradation condition of slew bearing rotating at very low speed (≈ 1 r/min) with naturally defect The literature study of existing research related to feature extraction methods or

Integrated Condition Monitoring and Prognosis

The bearing was naturally degraded during the experiment with rotational speed of 1800 rpm The prognosis of low speed bearings with naturally induced defects has not been explored Prognosis method has not been applied in the study of low rotational speed slew bearing [4 10 11] This paper present both condition monitoring and prognosis method
