Smart Machine Elements - Sensor-integrated Elastomer Couplings

Year: 2023
Type: conference-paper
Abstract: The available computational performance is steadily increasing.On this basis, digital twins become possible, but the need for data increases.In mechanical engineering, research in recent decades has focused on providing data based on external sensors, e.g.accelerometers.In contrast, in recent years, effort have been made to provide data directly from a machine element itself.The aim of this work is to outline the concept of a sensor integrated machine element (SiME), using the example of a sensor-integrated jaw coupling for "in situ" data acquisition and transmission.Elastic couplings are an integral component of the drive train and hold vast development potential.The jaw coupling will be able to measure the transferred torque.The determination of the torque is based on the measurement of capacity changes resulting from the deformation of the elastic teeth of the gear rim.Based on the high deformations of the tooth, a soft strain sensor made of dielectric elastomer material (DES) is integrated.Furthermore, it can be shown that the rotational speed and shaft misalignments can be evaluated based on the same data.In order to evaluate the sensor-integrated coupling both a static and a dynamic test bench are described.Therefore, different load cases are defined to evaluate the performance of the jaw coupling.They are focused on the visco-elastic behaviour of the materials used for the elastic gear rim.
