摘要： A non-collapsible flexible sealing membrane (or bellows) (100) for incorporation in a mechanical seal assembly and use in rotary shaft equipment. The sealing membrane includes a substantially radially outward extending first flange portion (102), which can be urged into an axially shiftable ring (36) by a biasing mechanism (500). The sealing membrane further includes a substantially axially outboard extending second coaxial portion (104), substantially radially inward of the balance diameter of the seal. The coaxial portion is advantageously held fixed to a stub sleeve (200) by an annular band (300). The angle between the flange portion and the coaxial portion of sealing membrane enables directional control of the forces acting on stub sleeve and first ring.

摘要： {Technical Problem} Provide a mechanical seal that allows for preassembly of its seal members on the stationary side, baffle sleeve, damper, and other related parts at a factory, service center, etc., in a reliable and controlled manner, thereby requiring fewer assembly steps during onsite engineering works. {Solution to Problem} The mechanical seal has a seal ring 9 and a mating ring 10 that faces and slides against the seal ring 9 and either the seal ring 9 or mating ring 10 is supported via a bellows 7 on the equipment interior side of a seal cover 2 installed on a housing 1, while the other rotates together with a rotational shaft 3; and a baffle sleeve 17 or 37 with a roughly L-shaped cross-section is fixed on the equipment exterior side of the seal cover 2 to guide quenching liquid to the sliding surfaces of the seal ring 9 and mating ring 10, where the baffle sleeve 17 or 37 is structurally split into a flange part 21 or 38 and cylinder part 22 or 38.

摘要： To provide a mechanical seal in which degradation or tearing of a bellows does not occur, the spring constant of the bellows is reduced, and the fluctuation in the load due to stretching and contracting of the bellows is reduced.
An inside-type mechanical seal comprising a sleeve (2, 20) fixed to a rotating shaft, and a cartridge (4, 40) fixed to a housing (3); a rotation-side sealing ring (5) being provided to the sleeve (2, 20); and a fixed-side sealing ring (6), which slides against the rotation-side sealing ring (5), and a bellows (7, 15, 30) for axially urging the fixed-side sealing ring (6), being provided to the cartridge (4, 40); the mechanical seal being characterized in that: the bellows (7, 15, 30) is made from a metal; and the metal bellows (7, 15, 30) has one end fixed to a case (8) for holding the fixed-side sealing ring (6) and another end fixed to the cartridge (4, 40), the plate thickness of the metal bellows (7, 15, 30) being set so as to be smaller than the plate thickness of the case (8) or the cartridge (4, 40).
