Concept of a sensor-integrating jaw coupling for measuring operating data

In recent years, industry and research (i) have driven the development and application of data-driven machines and systems and (ii) have increasingly introduced predictive maintenance. One of the main challenges is the acquisition of representative data for these applications. In the scope of mechanical systems, machine elements are the key parts for measuring process relevant data. Thereby, elastic couplings offer a considerable potential for a wide range of applications. The present work describes a novel space neutral sensor-integrating gear rim of a jaw coupling for the measurement of torque, rotational speed and temperature. The mechanical modifications on the coupling and the applied dielectric elastomer sensor are outlined. Additionally, the electrical conceptualization and the measurement chains are described. A manufactured prototype of the sensor-integrating jaw coupling and a proof of concept are presented.
