摘要： A stern tube sealing assembly and a seal ring thereof has a key part having an inverted V-shape, a front step part on the front side, and a back step part on the back side thereof. The seal ring width in a propulsion-shaft axis direction becomes thinner in the transition area from the key part toward a heel part. The inner diameter of the key part at the back step part is greater than that of the key part at the front step part. The ring has a lip part having a V-shaped lip tip protruding inwardly in the radial direction and a spring groove having a semicircular cross-section. The center of the spring groove is nearer to the inboard side than the lip tip, by an offset in the axis direction, the offset being within approximately 10% of the orthogonal projection length of the width of the lip back.

摘要： The invention provides a stern tube sealing apparatus which prevents an abrasion by cooling and lubricating a sliding contact surface of a first seal ring, prevents a foreign substance and a seawater from entering so as to further improve a durability of a seal ring and a liner, intends to make the sealing apparatus compact and reduce a cost by using no pressurizing apparatus, and has a high reliability of a seal system. In order to achieve the stern tube sealing apparatus, the structure is made such that the stern tube sealing apparatus is constituted by a plurality of seal rings slidably brought into contact with a liner of a propeller shaft, piping communicating with one of a liquid reservoir tank arranged so that a liquid pressure within the stern annular space is lower than a draft pressure on shaft center line is provided in a stern annular space defined by a first seal ring arranged on a stern side and a second seal ring adjacent to the first seal ring, and a feeding device for forcibly feeding the liquid in the stern annular space to the outside of a vessel having a higher pressure at a time of shaft rotation is provided on a sliding contact surface of the first seal ring and/or a sliding contact surface of the liner where the first seal ring and the liner are slidably brought into contact with each other.

摘要： (Means) A seal ring in which an apex part of the key part is formed so that the cross-section profile regarding the apex part forms a reversed V-shape toward the outside in the radial direction; the summit T of the reversed V-shape is formed as the middle center T of the apex part; a step part on the front surface side of the key part and a step part on the back surface side of the key part are formed so that the width of the seal ring in the axis direction of the ship propulsion shaft becomes thinner in the transition area from the key part toward the heel part; the inner diameter of the key part at the step part on the back surface side of the key part is greater than the inner diameter of the key part at the step part on the front surface side of the key part; a lip tip of the lip part forms a V-shape protruding inward in the radial direction and a spring groove having a semicircular cross-section in which a ringed spring is formed in the lip part; the center regarding the spring groove is arranged so as to be nearer to the inboard side than the position of the lip tip, by an offset in the ship propulsion shaft axis direction, the offset being within approximately 10% of the orthogonal projection length of the lip back width.
