SUBSTANTIATION OF REQUIREMENTS FOR LUBRICANTS OF AUTOMATIC LUBRICATION SYSTEMS OF RAILS

Abstract
The article deals with the question of substantiation of requirements for lubricants for automatic lubrication of rails and crests of rolling stock wheels. The mechanism of two-layer placement of the surfaces of the contact between the rail and the wheel is proposed, with the application of automatic lubrication, which corresponds to the maximum of the actual contact area and the minimum stress in contact, the friction and wear of the rails and crests of the wheels. The obtained dependences for determining the minimum of sufficient concentrations of solid antifriction dopants and surfactants in the lubricant. Such dependencies are the basis for substantiating the composition and structure of the lubricant when applying automatic lubrication of rails and rims of wheels from the point of view of realization in the contact of two-layered lubrication. They take into account the nominal area of friction, the microheometry of contacting surfaces, the shape and size of alloying particles, the thickness of the polymolecular boundary layer of surfactants.
