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 metal seal faces. A third ring is mounted to the second ring through a set of mounting pins which permit axial movement of the third ring. A biasing spring is mounting in the second ring and 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.

摘要： A sealing system includes a first gland in a cone and a first ring mounted in the first gland. A second ring is mounted to a shaft region. A third ring is positioned between the first and second rings. The first and third rings present a pair of metal seal faces. A second gland is formed between the second and third rings, with an o-ring sealing member installed within the third gland and radially compressed in a sealing relationship between the second and third rings. The second gland is sized to permit axial movement of the o-ring sealing member within the second gland in response to pressure changes. An energizer is configured to exert an axial force against the third ring so as to keep the metal seal faces in sealing contact. The axial force is applied at a radial position corresponding to a radial center the metal seal faces.

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.
