Model and Application of the Dispsersional aAnalysis for a Wear Study

Abstract

This paper shows a coherent calculation model of the unifactorial dispsersional statistic analysis applied for the experimental data study obtained on samples of different volumes, drawn out from a researched statistical population, on statistical principles. Based on the calculation model it was conceived an algorithm, that was applied in the study of wear dependence upon the characteristics of the grease lubrication of the researched coupling. The model and the algorithm have been applied for the qualitative and quantitative determination of the influence of the antiwear characteristic of the lubricating grease on the wear level of the rolling tracks of the “tulip-shaped shaft” semi-coupling from the structure of the angular joint with tripod from the Dacia passenger cars transmission.
