Three Rollers – Cone Test. New Possibilities of Wear Calculation

Abstract

In tests presented in the paper the authors made use of M.M. Chruščov’s concept of determining linear wear intensity Ih in model systems operating under constant load in which the contact stresses decrease in the effect of wear. They elaborated the mathematical model binding vertical approach of samples in four ball apparatus equipped with the three rollers – cone couple with rollers wear trace dimension. The model was verified in the special experiment obtaining a very good convergence of results of calculations and the experiment.
