Research methods - the analysis, statistics, generalization. Parameters of rational schemes of arrangement of cutters and ways of decrease in dynamic loading on screw executive bodies are developed. It will allow to lower breakdown susceptibility, to increase speed of giving of a combine and, hence, to raise efficiency of its work at working off of layers with difficult conditions of dredging of coal. Introduction of the offered technical decisions will allow to increase an operation reserve of screw maintenance period in 1,5-2 times, to lower equipment downtimes, to raise a coal mining, to reduce quantity of a coal trifle. Scope - collieries of Ukraine irrespective of patterns of ownership. Product Description popup.authors Іванчишин С.Я. Антіпова Н.П. Лелека В.І. Шведик П.П. popup.nrat_date 2020-04-02 Close
