Dignosis of Pulley-Belt System Faults Using Vibration Analysis Technique

Abstract

This work presents the pulley-belt system faults like unbalance, misalignment, belt worm and resonance. Which dedicated by vibration analysis technique, this system built and an experimental results had been obtained to find out the types of faults that appeared in the manufactured system. A selected faults have been created where the resulted dynamic response has been analyzed. The vibration results obtained by manufactured system by sensors ADXL335 (3-axis accelerometer) mounted on bearing brackets of drive and driven shafts. These sensors connected to Arduino type mega 2560 (microcontroller) which sending the data of vibration to the laptop in order to display it in Sigview software as a time and frequency domain band by FFT (fast Fourier transform).The results of FFT explained the effect of each type of faults comparing with the optimum condition FFT of the system.
