Essay

The thesis is devoted to the reduction of dynamic loads sharoshechnogo drilling machines by selecting and substantiation of rational parameters of the dynamics of the rotation of drilling puts roller cone drilling machines. Mathematical modeling of the drilling rod vibrations. A physical modeling of the drilling rod with the help of software package SolidWorks. It has been established that the cause of the extreme dynamic loads nodes roller cone drilling machines are resonant oscillations drilling rod. Implemented to provide a device with cover sliding support between the upper and lower ends of the drilling rod (NSP). To test the effectiveness of designed working model of drilling rod to meet the geometric and kinematic similarity conditions. Industries - mining (technical sciences)
