Abstract

Буровое долото, содержащее корпус и породоразрушающие органы с вооружением, которые с помощью подшипниковых опор смонтированы на корпусе один внутри другого, внутренний из которых установлен с угловым наклоном относительно оси долота, а наружный - с угловым наклоном в противоположную сторону относительно оси долота, отличающееся тем, что вооружение породоразрушающих органов выполнено в виде съемных концевых насадок (матриц) из износостойкого материала и армировано вставками (зубками) из твердого материала, при этом подшипниковая опора каждого породоразрушающего органа оснащена устройством для регулирования величины осевой игры (или предварительного натяга).A drill bit containing a body and rock cutting bodies with armament, which are mounted on bearings inside one another using bearing bearings, the inside of which is installed with an angular inclination relative to the axis of the bit, and the external one with an angular inclination in the opposite direction relative to the axis of the bit, characterized in that the weapons of rock cutting bodies are made in the form of removable end nozzles (matrices) of wear-resistant material and reinforced with inserts (teeth) of solid material, while the bearing support each rock-destroying organ is equipped with a device for regulating the magnitude of the axial play (or preload).
