Dynamics study and diagnostics with vibration analysis from worm gear manufactured by reverse engineering techniques

The study of the wheels and worm systems has been the subject of several studies. An important parameter that is not mentioned is the method and the means of manufacture of the wheels and worm to answer a problem of maintaining machinery. We use reverse engineering techniques in order to create a CAD model of non-standard worm and wheel. The paper is concerned with the dynamic study of worm and wheels. Based dynamic model a test stand is developed in order to achieve diagnostics with vibration analysis. We present our results in this article regarding the acquisition and processing of vibratory signals from accelerometers placed on a test stand for worm and wheels. We use signal treatment techniques in order to extract statistical indicators that indicate the quality of the gears.
