Abstract
Изобретение относитс к технике и технологии бурени нефт ных, газовых и других скважин и может быть использовано при проектировании, изготовлении и эксплуатации буровых шарошечных долот дл повышени долговечности шарошки за счет равностойкости зубьев на изгиб. Шарошка состоит из корпуса 1 с венцами, на которых расположены твердосплавные вставные зубь 2. На каждом венце шарошки геометрически параметры зубьев 2 и их угловой шаг св заны следующим соотношением: (hn Sn ) : (0,1 dn3) const, где hn - высота зуба n- го венца; Sn - площадь поверхности притуплени вершины зуба n-ro- венца; - угловой шаг зубьев n -го ве нца; dn - диаметр основани зуба п-, го венца. При работе шарошки зубь , выполненные по указанному соотношению, нагружаютс с одинаковой интенсивностью, а их равностойкость предупреждает преждевременное разрушение зубьев. 3 ил.The invention relates to the technique and technology of drilling oil, gas and other wells and can be used in the design, manufacture and operation of roller cone bits to increase the durability of the roller cone due to the equal stability of the teeth for bending. The roller cutter consists of a housing 1 with crowns, on which carbide false teeth 2 are located. At each rim of the roller cutter, geometrically, the parameters of the teeth 2 and their angular pitch are related by the following relationship: (hn Sn): (0.1 dn3) const, where hn is the height the tooth of the nth crown; Sn is the surface area of the bluntness of the tooth tip of the n-ro- ring; - the angular pitch of the teeth of the nth century; dn is the diameter of the base of the tooth of the p-, th crown. During operation, the tooth cone made at the specified ratio is loaded with the same intensity, and their equal stability prevents premature destruction of the teeth. 3 il.
