Description

Изобретение относитс  к вооружению шарошки бурового долота.This invention relates to the armament of a drill bit.

Вооружение шарошки бурового долота, состо щее из твердосплавных стержней, заделанных в тело шарошкн, известно.The armament of a drill bit cone, consisting of carbide rods embedded in the body of a drill bit, is well known.

Описываема  шарошка отличаетс  тем, что, с це,дью увеличени  ее стойкости , зубь  выполнены шаровидной формы.The described roller cutter is characterized in that, with a price, due to an increase in its durability, the tooth is made spherical in shape.

На чертеже изображено крепление зубьев шаровидной формы в теле шарои ки. В шарошке высверлены гнезда диаметра, соответствующего размеру шара.The drawing shows the attachment of spherical teeth in the body of a sharoki. In the roller cutter drilled diameter socket corresponding to the size of the ball.

Глубина гнезда меньше диаметра шара. В нижней части гнезда уложен пластичный материал (металлическа  стружка, спирально свита  проволока). Шар запрессован вThe depth of the nest is less than the diameter of the ball. Plastic material is laid at the bottom of the nest (metal chips, spiral wire). The ball is pressed into

гнездо, а кромка отверсти  зачеканена в такой степени, чтобы образовавшийс  валик плотно прилегал к поверхности шара, но позвол л ему проворачиватьс .the nest, and the edge of the hole is stamped to such an extent that the resulting roller fits tightly against the surface of the ball, but allows it to turn.

Эти два обсто тельства: пластична  подушка под шаром и возможность шара проворачиватьс -должны содействовать более равномерному износу шара и стойкости шарошки долота.These two circumstances: plastic cushion under the ball and the ability of the ball to turn - should promote more uniform ball wear and durability of the bit cone.

Предмет изобретени Subject invention

Шарошка бурового долота с зубь ми из твердого сплава, отличаюш , а   с   тем, что, с целью увеличени  стойкости шарошки, ее зубь  выполнены шаровидной формы.The cone of a drill bit with carbide teeth is different, and with the fact that, in order to increase the stability of the cone, its teeth are spherical in shape.
