Abstract
The disclosure of this method is intended for the predictive maintenance market, presenting an innovative method for detecting faults in hydraulic couplings, crucial components in power transmission systems across various industrial sectors. Slippage in hydraulic couplings, which is a loss of efficiency in torque transmission, can indicate wear, insufficient / excessive lubricant, or other problems, resulting in unplanned downtime and maintenance costs. The method uses metrics extracted from vibration signals to identify slippage, such as SFI (Slipping Frequency Indicator) and SNR (Signal-to-Noise Ratio). The combination of these metrics and other signal processing allows for accurate and reliable slippage detection, preventing catastrophic failures in industrial systems.
