摘要： A sealing system includes a first gland in a cone and a second gland in a shaft region. A first ring is mounted in the first gland, a second ring is mounted in the second gland and a third ring is positioned between the first and second rings. The first and third rings present a pair of opposed metal seal faces. A biasing spring is configured to exert an axial force against the third ring so as to keep the metal seal faces in sealing contact. A third gland is formed between the second and third rings, with an o-ring sealing member installed within the third gland and compressed in a sealing relationship between the second and third rings. The third ring includes a sealing region supporting the metal seal face and a body region supporting the third gland, with the sealing region pivotally coupled to the body region.

摘要： A drill tool includes a cone mounted for rotation on a bearing shaft that extends from a bit head. The cone has a first planar base surface opposed to a second planar base surface of the bit head. A first annular groove is formed in the first planar base surface, and a second annular groove is formed in the second planar base surface. The first and second annular grooves are at least partially aligned with each other. The combination of the first and second annular grooves form a first annular gland. A protector ring is inserted into the first annular gland, and functions to divide a fluid path between the bearing shaft of the drill tool and an external environment into a plurality of parallel fluid paths that pass around the protector ring. Each parallel fluid path includes a convolution defined by a plurality of fluid direction changing corners.

摘要： A drill tool includes a bit body, at least one bearing shaft extending from the bit body and a cone mounted for rotation on the bearing shaft. An outer bearing surface of the bearing shaft includes a non-loading zone. A first groove and a second groove are formed in the outer bearing surface at the non-loading zone. The first and second grooves are both circumferentially offset from each other and axially offset from each other. One or more of the grooves includes an opening for making a fluid connection to an internal lubricant channel within this bearing shaft. The circumferential and axial offsetting of the first and second grooves define a plurality of attenuation zones that function to restrict propagation of a cone pumping pressure pulse towards a sealing system of the drill tool.

摘要： A drill tool comprises includes a bit body, at least one bearing shaft extending from the bit body and a cone mounted for rotation on the bearing shaft. The bearing system for the tool includes a radial thrust bearing from which cone pumping pressure pulsation originates. A lubricant sealing system including an annular seal gland and a seal ring retained within the annular seal gland functions to retain lubricant in the bearing system. The tool further includes a lubricant cone pumping pressure restrictor system formed by an annular gland (separate from the annular seal gland) and a pressure restricting ring retained within the annular gland. The lubricant cone pumping pressure restrictor system is positioned between the radial thrust bearing system and the lubricant sealing system and is adapted to attenuate cone pumping lubricant pressure pulsation from acting on the seal ring retained within the annular seal gland.
