Description

Известны шарошечные долота, у которых все венцы выполнены либо с фрезерованными зубь ми, либо сплошными.Roller bits are known, in which all the rims are made with either milled teeth or solid ones.

Однако долота с фрезерованными зубь ми на периферии имеют недостаточную стойкость в процессе бурени  твердых и абразивных пород , а долота со сплошными венцами малоэффективны при бурении перемежающихс  в зких пород.However, chisels with milled teeth on the periphery have insufficient stability in the process of drilling hard and abrasive rocks, while chisels with solid rims are ineffective when drilling intermittent viscous rocks.

С целью повышени  эффективности бурени  3 предлагаемом изобретении только периферийные венцы одной или нескольких шарошек выполнены сплошными, а остальные - зубчатыми .In order to increase the drilling efficiency of the present invention, only the peripheral rims of one or several cones are made solid, and the rest are serrated.

На чертеже показано предлагаемое шарошечное долото.The drawing shows the proposed roller bit.

На лапах долота смонтированы шарошки 2 с фрезерованными зубь ми 3. Периферийные венцы 4 выполнены сплошными.On the paws of the bit, the cutters 2 are mounted with milled teeth 3. The peripheral rims 4 are solid.

Предмет изобретени Subject invention

Шарошечное долото с шарошками, снабженными основными и калибруюш,ими венцами, отличающеес  тем, что, с целью повышени  эффективности бурени , его калибруюш,ие венцы выполнены сплошными.A cone bit with cones, equipped with basic and calibrated bits, characterized by the fact that, in order to increase the drilling efficiency, its gauge, and the rims are made solid.
