Abstract
Nowadays, a special attention is focused on the development of modern devices and methods for monitoring condition changes of tribomehanical characteristics in systems. There are different physical and chemical methods and tribology methods for tribomehanical system diagnosis. Experience in technical systems exploitation showed that the most effective failure prognosis is based on particles created as a result of wear. The analysis of oil samples containing particles-products of wear, enables the evaluation of system tribology conditions in different phases of system exploitation. The paper presents the tribological tests in the analysis of oils used for the assessment of its condition. The paper also deals with the results of the experimental research of tribological characteristics of motor and power transmitter oils sampled from engines and power transmitters of the Mercedes O 345, PUCH 300GD and PINZGAUER 710M vehicles in exploitation. The investigations showed that there is a change of tribological characteristics of lubrication oils in the vehicle engine and power transmitters. These changes are in a direct dependence of the state of all elements of the tribomechanical engine and power transmitters system, and they depend on their functional characteristics. The conclusion is based on the realized testing.
