Keywords:
tribosystem of sliding, coefficient of friction, angle of deviation, balanced state.Abstract
In this paper, we propose ways to determine the static and dynamic coefficients of slip friction based on the results of calculating the corresponding friction angles of a cylindrical tribosystem of the type "shaft - sleeve" and a device for implementing such a method. The determination was carried out by measuring the angle of deviation of the ring from the balanced state. For static coefficient of friction under the influence of friction in the area of real contact after stopping the movement pre-biased ring toward a balanced state. For a dynamic friction coefficient for measuring the angle of deviation of a ring from a balanced state, which was installed and maintained under the action of the force of the reaction of the rough surface of the frictional force in the zone of the moving contact.
