diagnostics of roller bearing
combustion engine fittings - Opis:
- The roller-bearings are the most widely used appliances of the engine's fittings. The regular use of the roller-bearings leads to their degradation and subsequently to their damage. In extreme situations, the damaged roller-bearing can come to a standstill leading to the engine's failure. As for the maintenance of the engine, it would be crucial to work out the methods of supporting the diagnosis of the engine's fittings and its elements. The methods would enable to determine the condition of measure without the need ofthe disassembly. The vibroacoustic methods present the greatest possibilities in that field. The authors attempted to realize that task for a chosen element of the combustion engine's fittings in a car. The article presents the results ofthe conducted research and the study concerning the diagnosis of the bearing's timing belt tensioner pulley. The investigation was conducted for new roller-bearings as well as damaged. Different values of tension in investigations were applied by timing belt, which were placed for help of instrument PR-20. The accelerations of radial vibrations of screw fixing the tensioner pulley were measured during experiments. The recording of accelerations of vibrations was done for different constant engine speeds. The results ofthe research were analyzed by using software MatLab. The study indicated the measure sensitive to the changes of the technical condition of the tested element. The findings obtained confirm the usefulness of the presented method which in the form of a suitable algorithm may use as the basis for creating a diagnostic device.
