Abstract
Изобретение относитс к породоразру- шающему инструменту. Цель - повышение механической скорости бурени за счет большей интенсивности разрушени рейки за оборот шарошки. Шарошка 1 бурового долота включает венцы с группами фрезерованных зубьев 2, 3, 4 и 5, по-разному ориентированных относительно образующей. Зубь в одной из групп 3 выполнены с углом наклона 15-75° к образующей шарошки на длине окружности венца от 1/2 до 2/3 Зубь другой группы 2 выполнены ориентированными вдоль образующей шарошки. При перекрывании шарошек по забою более короткие зубь 2 и 4 создают максимальное удельное давление на породу, накатыва рейку, а зубь 3 и 5 обеспечиваю- ускоренное разрушение выступов рейки. 1 ил.The invention relates to a rock cutting tool. The goal is to increase the mechanical drilling speed due to the greater intensity of the destruction of the rails per revolution of the cone. The cutter 1 of the drill bit includes crowns with groups of milled teeth 2, 3, 4 and 5, differently oriented relative to the generatrix. The tooth in one of groups 3 is made with an inclination angle of 15-75 °; to the forming cone on the circumference of the crown from 1/2 to 2/3 the Tooth of another group 2 is made oriented along the forming cone. When overlapping cones along the face, shorter teeth 2 and 4 create maximum specific pressure on the rock, rolling the staff, and tooth 3 and 5 provide accelerated destruction of the projections of the staff. 1 ill.
