Abstract:

Learning Machine "Sign Language" by learning how vibration signals   reveal problems from planetary gear it is important from reliability point of view, as we know the bath curve also can give us a sign about the health of system. The topic of this chapter is to show that a solution for my improvement quality can be the following idea:  Unlike people who have verbal skills, machines use "sign language" to communicate what hurts or what has invaded their system. Recognizing the "signs" or symptoms that the machine conveys is a required skill for those who work with machines and are responsible for their care and feeding. This involves training, practice and motivation, but not at last give to the engineer the opportunity to design from the beginning the product by using the mathematical model of the planetary gear, more useful in improving the quality of the system and not waiting until the product will be failed and establish the cause.
