摘要： An elastomeric seal ring is located between each bearing pin and each cone of an earth-boring bit. An excluder ring or band is imbedded within the inner diameter of the seal ring. A portion of the inner diameter of the seal ring as well as the excluder ring are in dynamic sealing contact with the bearing pin. The excluder ring may be harder and more wear resistant than the seal ring. The excluder ring may have lubricating properties. An outer excluder ring may be located on the outer diameter of the seal ring for engaging the cone to resist rotation.
摘要翻译：每个轴承销与钻地钻头的每个锥体之间都有一个弹性密封圈。排阻环或带嵌入在密封环的内径内。密封环的内径的一部分以及排阻环与轴承销动态密封接触。排除环可能比密封环更坚硬并且更耐磨。排除环可以具有润滑特性。外密封环可以位于密封环的外径上以接合锥体以抵抗旋转。

摘要： A roller cone bit having an elastomeric seal (50) with a self break-in property is disclosed. The elastomeric seal includes abrasive material (54) on a sliding surface (53) for facilitating break-in. During break-in the abrasive particles smooth -the sliding surface on the bit leg by removing protrusions or surface roughness that results from machining the sliding surface and which may damage the seal's elastomeric body.

摘要： An earth boring bit has a bit body (13) with at least one bearing pin (15). A cone (16) is rotatably mounted on the bearing pin (15). A seal assembly (19) is located between the cone (16) and the bearing pin (15), the seal assembly (19) having at least one flexible seal member (25,31). A flexible pressure compensating diaphragm (17) is mounted in the body (13). The diaphragm (17) has one side adapted to be exposed to borehole fluids and another side in contact with lubricant contained in bearing spaces between the cone (16) and the bearing pin (15). The flexible seal member (25,31) and the diaphragm (17) are, formed of a fluprinated elastomer. The elastomer is either a perf luoroelastomer (FFKM) or a f luoroelastomer (FKM).
摘要翻译：钻地钻头具有带有至少一个轴承销（15）的钻头本体（13）。锥体（16）可旋转地安装在轴承销（15）上。密封组件（19）位于锥体（16）和轴承销（15）之间，密封组件（19）具有至少一个柔性密封构件（25,31）。柔性压力补偿膜片（17）安装在主体（13）中。隔膜（17）具有适于暴露于钻孔流体的一侧和与容纳在锥体（16）和轴承销（15）之间的轴承空间中的润滑剂接触的另一侧。柔性密封件（25,31）和隔膜（17）由氟化弹性体形成。弹性体是全氟弹性体（FFKM）或氟弹性体（FKM）。

摘要： A roller cone bit is provided that includes a wear resistant diamond-like carbon coating applied to a bearing shaft, where it is in sliding contact with the bearing seal. The wear resistant diamond-like carbon coating reduces wear and corrosion of the head bearing shaft sealing surface and provides extended life to the bearing seal.
