Abstract
La presente se refiere a mejoras en una cortadora rotatoria para barrenas de perforación, caracterizadas en que incluyen: un núcleo tenaz, metálico, cónico, resistente a la fractura con interior hueco y el cono define un eje geométrico; una capa radial de cojinete, anular, metálica, lleva en el interior del núcleo para soportar el núcleo para rotación y la capa de cojinete se extiende en torno al eje; una capa metálica externa resistente al desgaste en el exterior del núcleo; dientes metálicos integrales con el núcleo y que sobresalen del mismo y cuando menos algunos de los dientes están espaciados en torno al eje; una capa resistente a los impactos y al desgaste en cada diente para proveer filos duros cuando se hace girar la barrena en torno al eje.The present refers to improvements in a rotary cutter for drill bits, characterized in that they include: a tough, metallic, conical, fracture resistant core with a hollow interior and the cone defines a geometric axis; a metallic, annular radial bearing layer carries within the core to support the core for rotation and the bearing layer extends around the axis; a wear resistant outer metal layer on the outside of the core; metal teeth integral with and protruding from the nucleus and at least some of the teeth are spaced around the axis; an impact and wear resistant layer on each tooth to provide hard edges when the bit is rotated around the shaft.
