Abstract
Шарошка бурового долота, содержащая корпус и твердосплавные вставки с рабочей частью из двух поверхностей, одна из которых сферическая, установленные в корпусе со смещением вершины рабочей части в сторону, обратную вращению шарошки, отличающаяся тем, что, с целью повышения производительности бурения путем увеличения прочности и эффективности работы твердосплавных вставок, другая поверхность рабочей части выполнена в виде дополнительной сферической поверхности, сопряженной с основной сферической поверхностью, причем центры основной и дополнительной сферической поверхности расположены друг под другом и на одинаковом расстоянии от оси вставки, а их радиусы связаны соотношениемr≥ d/2 ≥ r,где r- радиус дополнительной сферической части, мм;r- радиус основной сферической части, мм;d - диаметр твердосплавной вставки, мм.A drill bit cone containing a body and carbide inserts with a working part of two surfaces, one of which is spherical, installed in the body with the top of the working part shifted to the side opposite to the rotation of the roller cutter, characterized in that, in order to increase drilling performance by increasing strength and the efficiency of carbide inserts, the other surface of the working part is made in the form of an additional spherical surface mating with the main spherical surface, with the centers of the main The additional spherical surface is located under each other and at the same distance from the axis of the insert, and their radii are related by the relation r≥ d / 2 ≥ r, where r is the radius of the additional spherical part, mm; r is the radius of the main spherical part, mm; d is the diameter of carbide inserts, mm.
