Maintenance Dortmund 2017: Predictive maintenance for gearboxes

At Maintenance Dortmund 2017, GfM is once again presenting systems and services for online condition monitoring and offline machine diagnostics for mechanical drives. These are used for predictive maintenance and thus help to minimize standstill due to unexpected machine failures.
 
An absolutely new feature is the offline vibration diagnosis system PeakStore5xx. The "xx" stands for the possible number of vibration channels: 04, 08 or 12. In addition, a maximum of two speed channels are recorded. The system can be remotely controlled via an app on a smartphone. So, no staff needs to be directly near the machine during the measurement.
 
Diagnosis is done preferably by order analysis. So, speed ripples have no influence and the
measuring results are absolutely reliable.
 
The operation is realized by a full-fledged integrated tablet PC and the software PAM. There
you can directly look at the data and analyze it locally. But you can also store additional information such as photographs and measurement protocols. Or you can send all data directly to a service provider like GfM, which creates an independent diagnostic report.
 
The PeakStore5xx itself has the dimensions 272 mm x 198 mm x 45 mm and thus a smaller base area than a DIN A4 page. The housing is designed for industrial use. Measurement times of 1.5 s up to 164 s as well as indeterminate can be set. During the indetermined measurement time, approximately 4 hours of measurement data can be recorded with 12 channels, each with a sampling rate of 51.4 kHz.
 
Acceleration sensors with IEPE coupling are used, typically. These are digitized with a sampling rate of 51.4 kHz and an amplitude resolution of 24 bits. However, other sensors (for example, displacement sensors) with AC or DC coupling and individually adjustable sampling rates can be measured by each channel.
