Analysis of reliability of cardan shafts based on condition diagnostics of bearing assembly in cardan joints

Abstract

This paper describes the reliability research of agricultural cardan shafts in laboratory and service test conditions. Reliability research is primarily focused on needle bearings resp. the bearing assemblies in joints of cardan shafts in agricultural machines. Using methods of technical diagnostics (temperature and vibration) we determined the influence of some operational parameters on the reliability of cardan shaft. For the purposes of testing the reliability of cardan shaft, we designed and manufactured a laboratory table for testing the reliability of cardan shafts, which can be also used for testing of other mechanical power transmitters.
