I Just Changed My Motor Bearings and They’re Bad Again!
When performing vibration analysis, it is observed that machines with VFD drives have a more frequent occurrence for changing motor bearings. If you’ve been diligent in the installation and maintenance of these machines, ensuring the alignment and balance are within specification and the bearings are properly lubricated, but still have frequent bearing failures, it may…Read More
Using Bearing Defect Factor for Gear Defect Detection
Bearing defect factor is a culmination of two technologies used for shock detection. DEF is designed as an indicator for bearing defect detection, but can also be valuable in the detection of gear defects. Why is DEF significant? In the following data set are displayed Overall Vibration Velocity, Overall Acceleration, and Defect Factor. The Overall…Read More
