Abstract
Изобретение относитс к бурению скважин . Цель - повышение надежности опоры путем исключени нагружени замкового элемента. На цапфе 2 опоры смонтирована шарошка 3 с отверсти ми, в которых установлены замковые элементы в виде паль цев 5. Между шарошкой 3 и цапфой 2 установлен опорный подшипник 4. В цапфе 2 выполнена уширенна кольцева проточка 6. Уширение направлено в сторону, противоположную торцу долота. Величина ушире- ни в 1,5-2,0 раза больше диаметра пальца 5. Шарошку 3 от схода с цапфы 2 удерживают пальцы 5. В процессе работы долота износ пальцев 5 и поверхности проточки 6 не происходит из-за отсутстви между ними контакта. 2 ил. (ОThe invention relates to the drilling of wells. The goal is to increase the reliability of the support by eliminating the loading of the locking element. Trunnion 2 supports are mounted with a roller cutter 3 with holes in which the locking elements in the form of fingers 5 are installed. A thrust bearing 4 is mounted between the cone 3 and trunnion 2. The broadened annular groove 6 is made in the trunnion 2. . The magnitude of the broadening is 1.5-2.0 times the diameter of the finger 5. The fingers 5 and the surface of the groove 6 do not wear out of the descent from pin 2 and hold the fingers 5 and the surface of the groove 6 because of the absence of contact between them. 2 Il. (ABOUT
