How can condition monitoring be used for early detection of gearbox damage?

Continuous analysis of vibration signals enables the identification of characteristic fault patterns at an early stage. With ibaPDA, vibration and process data are captured synchronously for evaluation. In ibaAnalyzer, frequency-based analyses allow specific defect patterns to be assigned to individual components. This enables reliable condition assessment before critical failures occur.

How can vibration and process data be combined for more accurate diagnostics?

Analyzing vibration data in isolation often leads to inaccurate results and higher false alarm rates. By synchronously capturing process variables such as speed and torque with ibaPDA, operational influences can be considered. In ibaAnalyzer, these datasets can be correlated and separated. This significantly improves diagnostic accuracy and reduces misinterpretation.

How can false alarms be minimized in condition monitoring systems?

False alarms are often caused by unaccounted process conditions or varying operating states. By defining specific frequency bands and linking them with process parameters in ibaAnalyzer, relevant vibrations can be distinguished from irrelevant ones. Historical data from ibaHD-Server further supports validation of alarm thresholds. This significantly improves alarm quality and reduces unnecessary interventions.

How does condition monitoring support predictive maintenance strategies?

Continuous trend analysis of condition indicators enables early detection of wear progression. ibaHD-Server provides long-term historical data for these analyses. Maintenance activities can therefore be scheduled during planned shutdowns. This reduces unplanned downtime and optimizes the lifetime of critical components.

How can complex drive systems in rolling mills be reliably monitored?

Complex systems require a holistic view of all relevant data sources. With ibaPDA, machine, process, material, and quality data can be captured synchronously. In ibaAnalyzer, these datasets are analyzed together to identify correlations and root causes of deviations. Only this integrated approach enables reliable detection of faults in complex drive systems.

Preventing Plant Downtimes With Condition Monitoring as Early Warning System

Monitoring Gears the Intelligent Way

Significant savings can be made with preventive maintenance using sensor-based Condition Monitoring. This is why Condition Monitoring gets more and more importance in major industrial plants over the last few years.

First indications of upcoming damages can be detected by acquiring and analyzing vibrations of mechanical components, before these damages might lead to plant downtimes and related production losses.

Detecting wear on mechanical components in a rolling mill early on in the process, was the main objective of this project, as in case of an unplanned failure of a drive train, the whole production unit would be down. For predicting downtimes with a high reliability, the implemented system can perform detailed analyses of complex plants.

The Technology

Due to the implemented Condition Monitoring System (CMS), worn components can be exchanged during theregular maintenance cycles and consequential damages by defective components and unplanned plant downtimes can be prevented. For this purpose, the system analyzes vibration signals, searches for characteristic damage patterns and calculates the current damage level based on these data.

In the production plant, numbers of revolutions per second, torques and other process values of the rolling stands are acquired by means of iba components and can be set into relation to the vibration data. Thus, the predictions can be improved significantly, as process-induced vibrations can be set into relation to the production behavior.

Due to the correlation of the process data and the comparison to historical data, very informative trend views of the long-term behavior can be created. In case of a damage, every gear component generates a characteristic disturbing vibration due to its mechanical properties. This way, damages on the components can be identified by means of specifically defined frequency bands. Thus, defective components can be detected in a reliable way. Hence, false alarms are being prevented and a predictive maintenance becomes possible.
