Description
Известны шарошки буровьк долот с твердосплавными зубками, запрессованными в гнезда, выполненные на венцах конической формы. При сверлении гнезд на таких венцах их входна кромка получаетс седлообразной формы, что ухудшает направление зубка в начальный момент запрессовки и ослабл ет его крепление. При этом возможны лерекас и полное нарушение сопр жени «зубок- гнездо.Known cone drill bits with carbide teeth, pressed into the socket, made on the cones of the conical shape. When drilling nests on such rims, their entrance edge is saddle-shaped, which degrades the direction of the insert at the initial moment of pressing in and weakens its fastening. At the same time, lerekas and a complete mating disturbance “teeth-nest” are possible.
Дл повышени прочности креплени зубков предлагаетс шарошка, в которой профили поверхностей венцов в сечении по образующей ша,рош;ки имеют частей окружностей с центрами, расположенными па оси шарош ,ки.In order to increase the fastening strength of the teeth, a cone is proposed, in which the profiles of the surfaces of the rims in cross section along the generator shaft, the rosh ki have parts of circles with centers located on the axis of the roller cone, ki.
На чертеже .показана описываема шарошка .The drawing. Described describes a roller cutter.
.Венцы J-3 шарошкн в сечении по ее образуюндей выполнены в форме частей окружностей с соответствующими радиусами i-R, размещенными на оси шарошки. При сверлении гнезд 4 под зубки на указанных венцах их входна кромка получаетс кольцевой. Это исключает перекос зубков в начальный момент заирессавки и ловышает прочность их креплени в гнезде.. The crowns J-3 cones in cross section along its line are made in the form of parts of circles with corresponding radii i-R located on the axis of the cone. When drilling sockets 4 for teeth on the specified rims, their entrance edge is annular. This eliminates the misalignment of the teeth at the initial moment of the air press and balances the strength of their mounting in the socket.
Предмет изобретени Subject invention
Шарошка бурового долота с венцами дл твердосплавных зубков, отличающа с тем, что, с целью повышени прочности креплени зуб.ков, профили пО|ВерХностей венцов в сечении по образующей шарошки имеют форму частей окружностей с центрами, расположенными «а оси шарошки.The bit of a drill bit with crowns for carbide inserts, characterized in that, in order to increase the strength of the attachment of the tooth., The profiles of the crowns in the cross section along the forming roller cutter are shaped as parts of circles with centers located on the axis of the cutter.
