Description

Примен емые шарошечные долота, у которых затылочна  часть перифврийных зубьев ар мирована твердым сплавом, не обеспечивают сохранение посто нного диаметра скважины из-за быстрого износа зубьев.The roller cone bits used, in which the occipital part of peripheral teeth is reinforced with a hard alloy, do not ensure the preservation of a constant bore diameter due to the rapid wear of the teeth.

Пре)длагаемое шарошечное долото отл1ичабтс  от известных тем, что имеет следуюш.ие особенности- Внешние трехгранные углы зубцов нериферийного ржда скруглены по радиусу и -имеют в сечении скругленной части двухгранный угол, вершина -чоторого образует рабочее ребро, служащее продолжением ребра основной части зуба. Эатылочна  часть зубьев периферийпого р ;да дл  устойч1:вости от износа армирована пласт1инка ш твердого сплава.The preliminary roller cone bit differs from the known ones that have the following features: The external triangular angles of the teeth of the non-peripheral horn are rounded along the radius and have a double angle in the cross section of the rounded part, the top of which forms the working edge serving as an extension of the rib of the main part. The peripheral part of the teeth of the periphery; for stability: wear is reinforced with a hard alloy plate.

Долото с предлагаемой «он.л-рухцие зубцов периферийного р да и армировкой затылочной части обеспечивает лучшие показатели работы при сохранении диаметров долота и, следовательно, скважины.The chisel with the proposed “on-liter teeth of the peripheral row and the reinforcement of the back of the head provides better performance while maintaining the diameters of the bit and, therefore, the well.
