摘要： A rotary cone drill bit is provided with at least one cutter cone assembly having a machined cutting structure which will maintain an effective cutting profile despite abrasion, erosion and/or wear of the associated cutting elements. The machined cutting structure may be formed on a generally cone shaped blank by a series of lathe turns and/or plunge cuts. The cutting elements may be formed with an aggressive cutting profile. For one application, the crest of each cutting element has the general configuration of an ogee curve. A layer of hardfacing material may be applied over all or selected portions of the machined cutting structure.

摘要： The body of a raise boring head is produced from a truncated cone. A variety of efficient and economical methods such as spin-forming, casting, rolling, etc. may be used in producing the truncated cone body. A multiplicity of rolling cutters positioned in cutter saddles are mounted on the truncated cone body. The mounting surfaces for the cutter saddles are on a continuous plane. The continuous plane can be produced on the truncated cone body in one turning operation. The raise boring head is self-cleaning due to the natural tendency of the cuttings to slide toward the periphery of the truncated cone body surface. The overall gross weight of the raise boring head is reduced and the strength-to-weight ratio is increased. The structural rigidity of the raise boring head is improved even though many of the structural components used in prior art raise boring heads have been eliminated.
摘要翻译：镗孔的头部由截锥制成。可以使用各种有效和经济的方法，例如旋转成型，铸造，轧制等，以生产截头锥体。定位在切割器鞍座中的多个滚动切割机安装在截锥体上。刀座的安装表面在连续的平面上。在一个车削操作中，可以在截头锥体上产生连续平面。由于切屑向截头锥体表面的周边滑动的自然倾向，起毛钻头是自清洁的。升高镗头的总体毛重减少，强度重量比增加。即使已经消除了现有技术中使用的许多结构部件，提高了镗头的结构刚度也得以改善。

摘要： A roller cone drill bit having a bit body with at least one support arm extending therefrom. Each support arm may have an interior surface and an exterior surface with an associated spindle extending inwardly from the interior surface. A respective cone assembly may be rotatably disposed on each spindle. A gap may be formed between interior portions of each cone assembly and exterior portions of the associated spindle with a fluid seal disposed in the gap to block fluid flow therethrough. Each cone assembly may include a generally circular backface disposed adjacent to the interior surface of the associated support arm. At least one fluid passageway may extend through each support arm to allow communication of fluid from the interior surface to an exterior surface of the support arm. A debris diverter insert having a generally hollow bore may be disposed within each fluid passageway.

摘要： A cutter assembly for rotary boring of earth. The assembly comprises a rotating cutter having a shaft protruding from the ends of the cutter; and a mounting member for the rotating cutter. The mounting member comprises two legs the ends of which are provided with counter surfaces for the ends portions of the shaft. The assembly further comprises fastening elements provided with a counter surface, the fastening elements being fitted at the ends of the legs for fastening the shaft to the mounting member. In order to provide a self-adjusting and reliable assembly which prevents the turning movement of the shaft, the curvature of the middle portion of the counter surface of the fastening element is so formed that a gap narrowing in the direction of the periphery of the shaft is defined between the shaft and the middle portion of the counter surface of the fastening element. A clutching part extending in the radial direction is arranged at the end of the shaft. When the shaft turns, the clutching part is pressed against the counter surface, thus preventing the turning of the shaft in this direction.

摘要： A raise head having a multiplicity of cutters for enlarging a pilot hole into a larger diameter hole by disintegrating the earth formations that surround the pilot hole is provided that will require lower cutter loads to penetrate the formations being bored by directing the rock fracture planes toward the pilot hole forcing the rock to yield with less input energy. The cutters are positioned on the raise head to provide an earth formation contact profile with a major portion of said earth formation contact profile extending outward and upward from said pilot hole. The included angle between the major portion of the earth formation contact profile and the axis of the pilot hole is less than 90.degree..

摘要： A roller cone drill bit having a bit body with at least one support arm extending from the bit body. Each support arm may have an associated spindle extending inwardly. A respective cone assembly may be rotatably disposed on each spindle. At least one diverter plug may be disposed in a hole formed in each support arm. A void space may be formed between one end of each diverter plug and the bottom of the associated hole. At least one fluid flow passageway may extend from the surface of the associated support arm to the void space to allow communication of fluid containing debris with the void space. Rotating action of the roller cone drill bit and associated cone assemblies may force packing of debris into the void space which results in biasing the diverter plug outwardly from the associated hole to contact adjacent portions of the associated cone assembly.
