Technological Providing of Surface Layer Wear Resistance of Machine Components
(UDJG, 2011)The article describes the problem of assuring the wear resistance of the friction surface layers based on the control of the geometrical, physical and mechanical properties to be formed after the machining process. -
The Application of CRN Coating in Sliding Pairs under Lubrication Conditions
(UDJG, 2011)This work revealed the results of the impact of the formed surface layer CrN and the surfaces layer CrN-steel 46Cr2 “ring” structure. The sliding pairs worked under conditions of lubricating the friction area with Lotos ... -
The Dynamic Behavoir of the Sliding Tribosystem in Cyclical Translation Motion in Unsteady Duty
(UDJG, 2011)The present paper deals with certain methodological aspects of researching the behaviour of the sliding tribosystem in cyclical translation motion from the point of view of the dynamics of contact processes. The dynamic ... -
The Influence of Nano-Particle Additive to Lubricating Oils on the Structure and Properties of Friction Surfaces
(UDJG, 2011)The article considers the influence of the additive in the lubricating oils Cermet, on tribological properties of a friction pair «cast iron – chrome», which is typical for the cylinder-piston unit of engines. It is shown ... -
The Influence of the Thermomagnetic Treatments on the Nitrided Superficial Layers Evolution after Wear Process (III)
(UDJG, 2011)Two types of steel grades were subjected to a nitriding thermo-chemical treatment after the thermo-magnetic treatments. The structural aspects of the superficial layers of these steels are studied after the friction process ... -
The Screw Fastening Order in Slewing Rings
(UDJG, 2011)The slewing rings are composed of two rings, an inner one and an outer one, in which raceways are obtained that, contains the rolling elements on which the working loads are transmitted from the moving ring to the fixed ... -
Theoretical Evaluation and Experimental Measuring of the Friction Forces from the Sealing of the Rod for the Hydraulic Cylinders
(UDJG, 2011)The paper presents some technical problems specific to the mobile sealing, used in the construction of hydraulic cylinders, and the theoretical and experimental methods which allow to determine the friction forces which ...
