Obtención de una base de datos de vibración, temperatura, energía y ultrasonido de la evolución del desgaste en ruedas dentadas

Abstract

The objective of this work was to obtain a database of wear in gear wheels through the analysis of vibration, temperature, energy and ultrasound. For which the gears with straight teeth were selected; the driving gear has 64 teeth while the driven gear has 24 teeth with and without lubricant. They were used in the simulation module and data collection. The selected failure mode was a broken tooth on a pair of gears. Measurements were made one minute apart, vibration data collection was performed on the electric motor by placing the accelerometer at the front of the motor (point 1) and at the rear of the motor (point 2). The thermographic analysis was carried out at one meter apart, the ultrasound analysis was carried out by placing the equipment as close to the gears in a vertical and horizontal radial direction. A database in .xlsx format with 2040 rows and 102 columns was obtained. The dispersion obtained from the data shows that as the motor works the temperature increases, while with a broken tooth the motor increases the evolution of the data taken quickly. Scatter plots were mate with the data extracted from the vibration spectra, where the study of the amplitude wave with healthy wheels and broken tooth was analyzed. The graph with healthy wheels shows a positive correlation with the data obtained, while with a broken tooth there is a dispersion of data produced by gear noise of the tooth due to the failure. It is recommended to use the database to carry out research work on gearwheels with broken tooth and healthy tooth using machine learning.
