Ovchinnikov O. Resource increase of underrail bearing plates, in curved underground railway track sections, by means of consistent lubricants

Object - process of wear of rail pad bearing flanges of "Subway" type in curvelinear areas of subway railway lines; aim - increase of assigned rail pad resource of "Subway" type in curvelinear areas of subway railway lines by means of applying grease lubricantion; techniques - study of influence of grease lubrication on rail fastening resource of "Subway" type has been carried out by means of theory of reliability, systems analysis methods, modern provisions in physics, triboengineering and mechanics. Experimental studies used mathematical statistics techniques and elements of and theory of planning of experimental studies, contemporary techniques and means of engineering measurements; novelty - generality of process of lining wear in coupling " rail base edge - rail pad flange" while using grease lubricantion has been established; theoretical foundations of processes of wear applicable to coupling " rail base edge - rail pad flange" while using grease lubricantion have been further developed; rational periodicity of injecting greas lubricant into coupling " rail base edge - rail pad flange" have been established; results - means of increasing fastening resource of "Subway" type in curvelinear areas of subway railway lines by means of applying grease lubrication, techniques of injecting lubricant between friction surfaces in fastening of "Subway" type, as well as determination of greasing interval under service conditions; sphere of application - curvelinear areas of subway railway lines.
