Vibration monitoring of gear transmission

The paper shows an analysis carry out on a gear transmission through the test-rig. Our attention will be focused on the duration test and how to stop it if an unexpected event occurs. In the first part it is described the duration test assessment performed on the gear transmission. In the second part it is showed the set up of the gear transmission test and the selection of the right points for the measurement and the equipment used for the assessment. In the third part it is showed the algorithm for monitoring the test. The aim of the algorithm is to assure the test will be stopped if the gear transmission will be damaged for any reason. This algorithm, by detecting early the gear crack, gives us the advantage of assuring the integrity of the gear transmission and consequently the possibility of inspecting it.
