Abstract

Шарошечное долото, включающее шарошки со ступенчатым периферийным вооружением, отличающееся тем, что, с целью повышения показателей эффективности работы долота, соотношение размеров ступеньки и долота определяется какa/b=0,60-0,70, при/D=0,023-0,032,где- ширина ступеньки;b - высота ступеньки;D - диаметр долота. Roller cone bit, including cone with step peripheral armament, characterized in that, in order to increase the performance of the bit, the ratio of the size of the step and the bit is defined as a / b = 0.60-0.70, with / D = 0.023-0.032, where - step width; b - step height; D - bit diameter.
