Abstract

Герметизированная опора шарошки бурового долота, включающая лапу, шарошку, подшипниковую опору и уплотнение между лапой и шарошкой, состоящее из торцовой пары металлических колец, из которых неподвижное соединено с лапой, а подвижное связано с шарошкой, и амортизатора в виде металлической мембраны, которая соединена с указанным подвижным кольцом и связана с шарошкой, отличающаяся тем, что указанная мембрана связана с шарошкой через посредство осевого эластомерного уплотнительного кольца, которое радиально дистанцировано от указанной торцовой пары к периферии мембраны.A pressurized cone of the drill bit cone, including a paw, cone, bearing support and a seal between the paw and cone, consisting of an end pair of metal rings, of which the fixed is connected to the paw, and the movable is connected to the cone, and a shock absorber in the form of a metal membrane that is connected to said movable ring and connected with a cone, characterized in that said membrane is connected with a cone through an axial elastomeric sealing ring that is radially spaced from said ortsovoy pair to the periphery of the membrane.
