THEORETICAL EVALUATION OF SERVICE LIFE OF ROLLER CUTTER DRILL BIT BEARING ASSEMBLY, BASED ON FIELD TESTS<\/strong><\/p>\n

Rodion M. Bogomolov \u2013 PhD in Engineering, professor, director for advanced research, OJSC \u201cVolgaburmash\u201d, bogomolov@vbm.ru bogomolov@vbm.ru<\/a>;

Nikolay I. Dedov \u2013 PhD in Engineering, professor of SamGTU, press@samgtu.ru press@samgtu.ru<\/a>.<\/strong><\/em><\/p>\n

Key words:<\/strong> total service life of bearing assembly, empirical models, service life evaluation algorithm, probability of trouble-free operation.<\/p>\n

Absence of domestic methods of evaluation of total service life of drill bit bearing assembly TBR has long been a serious obstacle to foreign sales of drill bits supplied by OJSC \u201cVolgaburmash\u201d. The author proposes a mathematical model to evaluate TBR for custom conditions and drilling modes on the basis actual conditions, drilling modes and bit wear data.<\/p>\n
