Abstract :
In industry, especially car maintenance is essential. Agricultural machinery due to the high load, terrain, environments contaminated with dust and other unfavorable climatic conditions the accurate maintenance programs, regular, good quality consumer materials and components need to be. Otherwise, the cost will be very high maintenance machines specified in cultivation calendar, will not be accessible and usable. Therefore, applying a monitoring program to predict the exact time of the failure, reduce the intervals in the operation of agricultural machinery, Increased safety, efficiency, financial savings and overall increase in the harvest of the unit creates. Vibration analysis is the most powerful and most used method for identifying defects is gearing systems. The use of the frequency spectrum of the vibration machine components in order to determine the extent and location of the fault components of modern methods is in the process of electronic measuringvibrations. The aim of this study was to determine the defects associated with major components such as gears tractor hydraulic pump vibration frequency spectrum obtained by analysis by electronic measurement system was Vibrations. In order to measure the vibrations of a lab bench design and components of the measurement system, hydraulic pump MF399 tractor, electric motor was installed on it. Tests at two levels of 350 and 700 rpm for input shaft rotational speed hydraulic pump was. Including corrosion defects on the gear wheel pinion gears 25 and 50 percent on the first pump and the second pump corrosion was freewheeling gear. The operation was carried out by Vibrotest VT60 model. (The analysis of the data shown in the time and frequency domains The frequency of 5 to HZ105 at all speeds time with increased corrosion in gear, vibration in a higher frequency and amplitude less
