Roller bearing defect is a major factor of failure in rotating machinery that affects its proper functioning which results in substantial time and economic losses. Therefore, condition monitoring of roller bearing is important and the study of severity of defects are necessarily required in order to avoid catastrophic consequences. The analysis of signal resulting from measurements taken from outer machineries has proven to be effective, by detection of failure in bearings over rotating shaft. The authors have used a method based on the vibration analysis for detection of defects in rolling element bearings with single or multiple defects on different components of the bearing structure using the time and frequency domain parameters. A dynamic loading model is used in order to create the rotary motion of bearings. A vibration analyser is used for vibration diagnosis and on-sit...

Systems can scavenge power from human activity or derive limited energy from ambient heat, light, radio, or vibrations. Ongoing power management developments enable battery-powered electronics to live longer. Such advances include dynamic optimization of voltage and clock rate, hybrid analog-digital designs, and clever wake-up procedures that keep the electronics mostly inactive. Applying suck techniques to larger machines such as treadmill and bicycle, by using various dynamometers in a gym facility or at home can also produce renewable energy in large amount. Humans release a lot of energy from their everyday activities, such as simple breathing and walking. Energy harvesting's true legacy dates to the water wheel and windmill, and credible approaches that scavenge energy ...

Therefore, condition monitoring of roller bearing is important and the study of severity of defects are necessarily required in order to avoid catastrophic consequences. Defects monitoring during dynamic loading conditions of rotational machineries with the use of contactless, non-destructive infrared thermographic method is proposed. By using a rotating ball bearing, passive thermographic experiment was performed as an alternative technique to proceed the condition monitoring. Based on the results, the temperature characteristics of the ball bearing under dynamic loading conditions were analyzed thoroughly. Also, a comparison of these results was done for different bearings with characteristic defects. As a result, it was confirmed that infrared thermography method could be adopted to monitor and diagnose the faults by evaluating quantitatively and qualitatively the temperature characteristics according to the condition of the ball bearing.
