Description
В известных шарошечных долотах толщина зубьев шарошек иепропорциональна .их высоте , что приводит к притуплению резцов и снижению скорости бурени .In the known roller bits, the thickness of the teeth of the roller cutters is proportional to their height, which leads to blunting of the incisors and a decrease in the drilling rate.
В долоте согласно изобретению зубь шарашек выполнены с вогнутыми гран ми; этим обеспечиваетс посто нство сечени зубьев. При работе они притупл ютс меньше, чем уIn the chisel according to the invention, the teeth of the sharashkas are made with concave edges; this ensures the constancy of the tooth section. During operation, they are dulled less than that of
обычных долот, следовательно, возмож-но увеличить скорость бурени .conventional bits, therefore, it is possible to increase the speed of drilling.
Предмет изобретени Subject invention
Шарошечное буровое долото, отличающеес тем, что, с целью увеличени скорости бурени , боковые грани зубьев шарошек выполнены вогнутыми.Roller drill bit, characterized in that, in order to increase the speed of drilling, the lateral faces of the teeth of the rollers are made concave.
