ABSTRACT

Chemically active components which are available both in structure of material of a blanket and in lubricant, decay under the influence of temperature, a force field of a solid body and catalytic impact of a svezheobnazhenny surface of metal, are allocated in the form of active agents who react and form the modified layer. The modified layer has smaller (in comparison with the main metal) resistance to shift owing to what decrease in coefficient of friction and replacement of intensive adhesive wear softer corrosion and mechanical is provided. The condition of details of the rolling bearing in the presence of the modified layer does not change during all service life. However in case of a leakage of lubricant or loss in it chemically active components the modified layer is not formed that leads to metal contact and failure of the bearing. Metal contact causes sharp temperature increase, and also mechanical damages to a type of zadir on bodies of swing and nicks on the rings received as a result of shock loadings. Intensity of wear of details of the rolling bearing is influenced substantially by the process temperature which depends on the relative speed of sliding and the normal squeezing force. In process of temperature increase of process the speed of education and a share of the modified layer increase. Critical value of temperature determines a lubricant scope. The concentration of an active component in lubricant is higher, the wear resistance of the rolling bearing is higher. When toughening the mode of friction there is a competition of two processes – educations and wear of the modified layer and if wear prevails, then inevitably there will be a metal contact leading to failure of the bearing.

Editor-in-Chief, editorial board chair

Editor-in-chief of the journal Bulletin of Bryansk State Technical University KHANDOZHKO ALEKSANDER VLADIMIROVICH Aleksander Vladimirovich Khandozhko is Doctor of Engineering (2002), Associate Professor (1993), Honorary Worker of Higher Professional Education of the Russian Federation, Professor of the Department of Metal-cutting Machines and Tools at Bryansk State Technical University (BSTU). He was born in Chelyabinsk in 1958. In 1980 he graduated from Bryansk Institute of Transport Engineering (BITE) (now - Bryansk State Technical University, BSTU) with a degree in Mechanical Engineering Technology, Metal-cutting Machines and Tools. From 1980 to 1983, he worked as a manufacturing engineer at an industrial enterprise. From 1983 until now he has been working at Bryansk State Technical University, having started his career at the university as a training master. In 1985 he entered the full-time postgraduate course in BITE. In 1989 he defended the thesis for the degree of Candidate of Science in the Dissertation Council of Moscow State Aviation Technological Institute (MSATI) on the specialty Heat Engines of Aircrafts. After defending his thesis, he worked as an assistant and then as an associate professor of the department of Metal-cutting Machines and Tools at BITE. In 2000 he entered the post-doctoral program and in 2002 he defended his doctoral thesis on the specialty of Technology and Equipment of Mechanical and Physical-technical Processing. After defending his thesis, he worked as a professor of the department until 2009. In 2009 he was appointed the head of the department of Metal-cutting Machines and Tools at Bryansk State Technical University. In 2016 when the laboratory of wave deformation and combined hardening in additive and subtractive technologies was founded at BSTU, he became the head of the department of modular technological equipment, continuing his teaching work as a professor of the department of Metal-cutting Machines and Tools. Khandozhko A.V. is a member of the editorial board of the journal Science Intensive Technologies in Mechanical Engineering (Bryansk). Since 2002 he has been a member of dissertation councils of several universities; currently he is a member of three dissertation councils D999. 155. 03, D999.112.02 and D212.021.03 aa well as being the Deputy Chairman of Dissertation Council D999.155.03. Topics of scientific research 1. Fundamental theoretical and applied issues of designing cutting tools. 2. Theory and practice of designing and manufacturing process equipment, including for additive-subtractive processes. 3. Issues of mechanical processing of materials. 4. Problems of providing product quality in mechanical processing and additive processes.
