Sistema remoto para sensoriamento de torque em eixos rotativos

Abstract

Industries are constantly looking to improve the efficiency of their processes. An excellent option to improve operations, stay ahead of mechanical failures, save employee time, and reduce company costs is to measure and control torque on rotating equipment. This type of measurement makes it possible to perform preventive maintenance before major failures occur due to excessive torque, extending the life of the equipment. However, performing this measurement while the machine or system is in full operation is not an easy task, mainly due to the need to feed and transfer data while the system is rotating. In this paper, we propose a method for measuring torque data remotely on rotating shafts, using strain gauges, which are strain gauges that convert deformations into equivalent variations in their electrical resistance, together with a data acquisition and wireless communication system. After gluing the sensors and assembling the system, static and dynamic tests were carried out in order to calibrate and evaluate the developed system, as well as the performance test of the battery built into the system. The results of the static test allowed the calibration of the system, and the dynamic tests showed a good functioning of the proposed system. The battery performance test, on the other hand, showed a high consumption of the system, making it necessary to seek improvements.
