Abstract
Изобретение относитс к горной промышленности и предназначено дл бурени скважин. Цель - повышение эффективности бурени . Долото содержит корпус и зубчатые шарошки 1-3, периферийные венцы 5-7. Венец 7 имеет наибольшую длину зубьев и разделен на две части, выполненные с разным числом зубьев. Часть венца с большим числом зубьев расположена со стороны оси долота. Такое выполнение долота позвол ет исключить преждевременный износ части с большим числом зубьев, что повышает проходку на долото за счет более равномерного распределени вооружени по радиусу долота . 2 ил.The invention relates to the mining industry and is intended for drilling wells. The goal is to increase the drilling efficiency. The chisel includes a housing and a gear roller cutter 1-3, peripheral rims 5-7. Crown 7 has the greatest length of the teeth and is divided into two parts, made with a different number of teeth. Part of the crown with a large number of teeth located on the side of the axis of the bit. Such an embodiment of the bit makes it possible to eliminate the premature wear of the part with a large number of teeth, which increases the penetration rate of the bit due to a more even distribution of the weapon along the bit radius. 2 Il.
