STUDIES ON THE DEVELOPMENT OF A RELIABILITY DIAGNOSIS FOR AGRICULTURAL TRACTORS GEARBOXES
STUDII PRIVIND DEZVOLTAREA UNUI DIAGNOSTIC DE MENTENANȚĂ LA CUTIILE DE VITEZE A TRACTOARELOR AGRICOLE
Faults and failures analyses consist of a very varied field of technique, so concepts and reliability indicators help us to determine the types of faults easier, their appearance in functioning and mathematical relations for determining the types of failures. Regarding to, the test stands help us to identify accelerated of noises, vibration and serious faults that occur in use and can lead to disposal of equipment, helping engineers quickly find the optimal solutions for most cases. Current methods used to determine agricultural tractors gearboxes reliability are those in open energy flow, they better simulate the real working conditions. We design a gearbox test stand for a rapid noise and vibration reliability diagnoses and tests. Considering the gearbox work conditions and its random possible failures, the stand will be equipped with transducers and a data acquisition system for data collection.
