COMPARING EMBEDDED SOLUTIONS FOR MECHANICAL VIBRATION ANALYSIS OF A 3D-PRINTED CYCLOIDAL GEARBOX

Abstract

The vibration study of the cycloidal gear and the prevention of vibrations are important issues in the field of mechanical engineering. Cycloidal gears are used in many different applications, including industrial machinery, industrial robots and medical devices. Vibration tests of the cycloidal gear consist in identifying the sources of vibrations and determining their characteristics. As a result of the conducted research, the sources of vibrations can be identified and strategies for their reduction can be developed. Vibration studies of the cycloidal gear include spectral analysis, time-frequency analysis, vibration analysis, as well as verification of the impact of using other control methods (e.g. microstep control) on the generation of vibrations. A cycloidal gear made in 3D printing technology was used in the research. Ultimately, the gearing is to be used to move the robot's arm. The purpose of the research is to analyze vibrations, which will be used to control the robot to minimize vibrations, which will positively affect its accuracy and life. Ultimately, an active vibration monitoring system will be developed, where an Arduinotype microcontroller will be used. This system will monitor and warn against vibrations of dangerous amplitude. For the correct implementation of this system, tests will be carried out to compare the accuracy of the measurement using the developed system based on Arduino and the professional Digiducer 333d01 sensor.
