摘要： An elastomeric o-ring rock bit seal is disclosed with two or more integrally bonded elastomers or phenolic type materials joined together to form the seal. The dynamic sealing face adjacent the journal bearing is fabricated from an elastomer/phenolic engineered specifically for wear resistance The bulk of the seal adjacent the static seal retention cavity typically formed in the rotary cone is molded from an elastomer engineered specifically for precise control of the seal contact force adjacent the dynamic seal face when the seal is compressed against the dynamic face by the seal retention cavity in the cone.

摘要： A hydrostatic mechanical seal assembly includes a locally deployed pump for pressurizing a lubricant fluid between the opposing faces of a mating ring and a sealing ring. In one exemplary embodiment, such pressurization may be achieved via a device that converts the rotational motion of a drive shaft into fluid pressure. The locally deployed pump is intended to advantageously provide a stable positive pressure on the sealing interface between the mating and sealing rings, which may provide improved sealing characteristics, especially in demanding downhole environments.

摘要： A Moineau style stator includes a helical reinforcement component that provides an internal helical cavity. A resilient liner is deployed on an inner surface of the helical reinforcement component. The helical reinforcement component includes a solder or braze material and is typically metallurgically bonded to an inner wall of a stator tube. In exemplary embodiments, the helical reinforcement component includes a composite mixture of solder and aggregate. Exemplary embodiments of this invention address the heat build up and subsequent elastomer breakdown in the lobes of prior arts stators by providing a helical reinforcement component. Solder reinforced stators tend to be less expensive to fabricate than reinforced stators of the prior art.

摘要： A mechanical seal for use in a rotary rock bit comprises a leg seal ring positioned within a recessed portion of a leg forming a seal cavity. The leg seal comprises one surface partially engaged by a resilient material and an opposite surface comprising a first sealing surface. The mechanical seal also comprises cone seal ring positioned within a portion of a cone forming the seal cavity. The cone seal comprises one surface positioned within and attached to a recessed portion of the cone and another surface comprising a second sealing surface engaging the first sealing surface. The portion of the leg seal ring engaged by the resilient material engages a back face of the leg which includes a ramp, serving to urge the first sealing surface against the adjacent second sealing surface and create a sealing engagement. The first and second sealing surfaces are made from different hard materials each having a similar hardness of greater than 1000, and each material selected has a Knoop hardness difference of about 400 or less. The first and second sealing surfaces may be formed from materials the same as or different than materials forming the leg seal ring and cone seal ring, respectively.

摘要： A radially disposed thrust bearing surface formed in a rotary cone is provided with at least a pair of grooves and a ramp surface on the trailing edge of the grooves. The groove provides a lubricant reservoir and the ramp serves to generate hydrodynamic pressures during rotation of the rotary cone on the thrust surface of a journal bearing thereby distributing a film of lubricant on the opposing thrust bearing surfaces.

摘要： This invention consists of a floating spindle cap disposed between a spindle pilot bearing extending from a main journal bearing and a cone bore formed by a rotary rock bit cone secured to the journal bearing. The floating spindle cap is formed from a softer material than both the spindle bearing and the cone to accommodate for slight misalignments and edge loading between the journal bearings and the cone while working in a borehole.
