Abstract
Изобретение относитс к буровой технике, м.б. использовано дл бурени скважин в породах различной крепости малых диаметров и позвол ет повысить ресурс долота. Зубок бурового шарошечного долота содержит цилиндрический хвостовшч 4 и рабочую головку 1 сфернческон; конической или клиновидной ftopbi, пересекаемую с одной стороны от оси зубка сферической наклонной рабочей поверхностью (П) 2. При этом П головки 1 сопр гаютс линией пересечени (ЛП) 3 с цилиндрической П хвог.товика 4. Направленна к наружной поверхности долота П 2 выполнена с радиусом, равнътм радиусу долота, и пересекаетс с П головки 1 по ЛП 5, ас ци,пиндрической П хвостовика 4 - по ЛП 6. ЛП 5 и 6 образуют острые грани. При работе долота шарошка перекатываетс по поверхности забо . Зубки с Л 2, расположенные на периферю1 ньп венцах, нанос т удары по забою рабочей частью и производ т разрушение поверхности забо и калибрование стенок скважины. 2 п. (ОThe invention relates to drilling equipment, m. used for drilling wells in rocks of various strengths of small diameters and allows to increase bit life. The clove of a roller bit contains a cylindrical shank 4 and a working head 1 of spherical balls; conical or wedge-shaped ftopbi, intersected on one side of the axis of the clove by a spherical inclined working surface (P) 2. At the same time, P of head 1 is mated by intersection line (LP) 3 with cylindrical P x2 of bead 4. Directed to the outer surface of the bit P 2 with a radius equal to the radius of the bit, and intersects with the P of the head 1 through the LP 5, ac chi, the pindric P of the shank 4 through the LP 6. The LP 5 and 6 form sharp edges. When the bit is operating, the roller cutter rolls over the bottom surface. The teeth with L 2 located on the periphery of the rims strike the bottom of the working part and destroy the surface of the bottom and calibrate the borehole walls. 2 n. (O
