Early detection of gearbox failure
Its Automatic Mode Identification found a new operational mode in the equipment, caused by inner raceway failure in the high-speed shaft bearing, which ultimately led to the replacement of the entire gearbox.
The Mode Identification feature is powered by Viking Analytics' AMI unsupervised algorithm for multivariate time series. It performs multidimensional time series data segmentation and clustering in vibration data, detecting time periods in which the data exhibits a similar structure and reflecting them into operational modes.
MultiViz Vibration first detected an operational mode at the beginning of the life of the machine, identified as a normal operational mode. However, after 11 months, a new operational mode emerged, lasting for three months. The new mode was caused by a high-speed shaft bearing fault, which had only been caught by traditional maintenance techniques two months after the data first identified it.
