EXPERIMENTAL DETERMINATION OF FRICTION COEfFICIENT AT GEAR DRIVES

Abstract

Procedure of tribological investigation for identification of the dependence between coefficient of friction from sliding velocity and contact pressure is defined in this paper. Sliding speed and contact pressure are changing during the gear pair teeth conjugate action. Thereby and coefficient of friction has variable values. Experimental determination of the friction coefficient is performed on pinon-disk tribometer. Thanks to regular election pins and discs, there is implemented contact on line what corresponds to the real conditions in the gear pair teeth conjugate action. Dependencies of the friction coefficient on sliding speed and contact pressure were predicted, based on the data obtained by measurement.
