摘要： A drill bit is disclosed for maintaining a desired direction of drilling or to reduce the deviation already established. The drill bit includes a plurality of legs with each leg having a cone cutter rotatively supported thereon. A plurality of annular rows of cutting inserts are circumferentially mounted on the conical surface of each cutter. Each cone cutter further includes a heel portion adjacent the base of the conical surface. The heel portion is of sufficient mass to support the gage row of cutting elements. The gage row of each cone extends further out from the cone axis than any of the intermediate adjacent rows in such a manner that the annular area of the hole bottom cut by the gage inserts is lower than any other area cut by the intermediate rows of cutting inserts. This extended gage row construction enables the gage inserts to cut into any sloping wall to produce a sharp corner and bring the hole back into line with the drill string. The cutting inserts of each gage row include relatively large cutting faces in the direction of the sidewalls of the bore hole in order to have substantial surface contact with the gage of the bore hole.
摘要翻译：公开了一种用于保持所需钻孔方向或减少已经建立的偏差的钻头。钻头包括多个腿部，每个腿部具有可旋转地支撑在其上的锥形切割器。多个环形排的切削刀片周向地安装在每个刀具的锥形表面上。每个锥形切割器还包括邻近锥形表面的基部的跟部。脚跟部分具有足够的质量以支撑切割元件的量规排。每个锥体的规格行比锥形轴线进一步从任何中间相邻的行延伸出来，使得由量规插入件切割的孔底部的环形区域低于由中间切割行切割的任何其它区域插入。这种扩展的规格行结构使得计量插入件能够切割成任何倾斜的壁以产生尖锐的拐角并使孔返回与钻柱成一直线。每个规格行的切削刀片在钻孔的侧壁的方向上包括相对大的切削面，以便与钻孔的表面具有实质的表面接触。

摘要： A drill tool for drilling earth, rock, and the like in oil industry operations includes a body member having a passage in a pin portion thereof and extending longitudinally of the body member and between an open or fluid receiving end and a closed end and a plurality of circumferentially spaced arms or lugs extending generally longitudinally from the closed end of the passage in the body member and each having an axle portion thereon for rotatably mounting a respective one of a plurality of cutting cones each rotating about a respective axis intersecting with a longitudinal axis of the body member to define a respective acute angle therebetween. The drill tool has at least one flow passage through one of the arms or lugs for directing drilling fluid from the passage in the body member into the drill hole for sweeping the drill hole and removing drilling debris therefrom. Exterior surfaces of the axle portions each have a reservoir and at least one passage communicating therewith and extending to the respective exterior surface for circulating lubrication material within a cavity in the respective cutting cones and having seals thereby providing lubrication of engaging surfaces of the axle portions and cutting cones.

摘要： A lubricant reservoir is positioned in each arm of a three cone rotary rock bit to provide lubricant to bearings located between the bit''s rotary cone cutters and the bearing shafts upon which the cutters rotate. A seal is positioned between the cutters and the bearing shafts to retain lubricant in the bearing area and to prevent borehole fluids and debris from entering the bearing area. A pressure equalizing passage provides communication between the lubricant reservoir and the outside of the bit. A two-way valve is positioned in the pressure equalizing passage to prevent excessive pressure differentials from building up between lubricant in the lubricant reservoir and fluid outside of the bit by allowing lubricant from the lubricant reservoir to escape to the outside of the bit and allowing fluid outside of the bit to enter the lubricant reservoir.
摘要翻译：润滑剂储存器位于三锥形旋转岩石钻头的每个臂中，以向位于钻头旋转锥形切割器和切割器旋转的轴承轴之间的轴承提供润滑剂。密封件位于切割器和轴承轴之间，以将润滑剂保持在轴承区域中并防止钻孔流体和碎屑进入轴承区域。压力平衡通道提供润滑剂储存器和钻头外部之间的连通。二通阀定位在均压通道中，以防止润滑剂储存器中的润滑剂和钻头外部的流体之间的过大的压差被允许来自润滑剂储存器的润滑剂逸出到钻头的外部并且允许流体在钻头外面进入润滑油库。

摘要： An improved large diameter hole drilling bit consisting of a cutter head with a plurality of yokes fixedly mounted on the cutter head and a like plurality of roller cutters each rotatably mounted on a yoke. The drilling bit is adapted to be supported by a drilling rod which is rotated by a power unit of the drilling machine. During drilling operation, the cutter head is rotated about the axis of the drilling bit and at the same time the roller cutters are rotated about their own axes with respect to the yokes by contact to the rock or the like. Each roller cutter includes a load pin supported by the yoke fixed on the cutter head, a cutter cone having cutting teeth or individually replaceable tips thereon and bearing balls and/or rollers interposed between the cutter cone and the load pin so that the cutter cone is supported for free rotation on the load pin. Pressure-responsive seals and dust filters prevent foreign material from passing into the bearings. The load pin, cutter cone and bearing are preferably held in permanent assembly.

摘要： A rock cutter formed of a stack of juxtapositioned cutter discs, said discs each having projecting carbide bits and being mounted on a rotatable shaft for rotation therewith. All bits have a common mounting plane, but extend therefrom in a graduated progression- from disc to disc. Also, each disc has its own distinct proportions, being of only a graduated different size compared to a disc to either side thereof.
