Abstract
The invention provides a wide seal and relates to the technical field of fluid mechanical rotary seals. The wide seal comprises a carrier base (2) and a sealing ring face (1) arranged on the carrier base (2). The sealing part of the wide seal is provided with a circular wide sealing face (3). The left and right sides of the sealing ring face (1) are alternately arched or bent on the wide sealing face (3), and thus any point, corresponding to a sealing member, of the wide sealing face (3) is in intermittent contact with the sealing ring face (1). The radiating performance of the wide seal is improved.
Description
Technical field
The present invention relates to fluid machinery rotary seal technical field, especially relate to a kind of wide sealing.
Background technique
Fluid machinery rotary seal, refer to that the corresponding Sealing to having relative rotary motion seals, corresponding Sealing wherein comprises axle, hole, end face etc.In seal process, corresponding Sealing contacts and relative sliding with seal ring face (lip), and sliding process frictional heating is serious.Especially, traditional seal ring face and continuous contact between corresponding Sealing, cannot dispel the heat timely and effectively in rotary movement, and the heat continuing accumulation accelerates the aging of seal ring face, causes sealing effect premature failure.
To sum up, fluid machinery rotary seal, makes great progress in the research of technician, but need to improve in aging heat radiation.For improving the radiating effect of sealing further, the invention provides a kind of sealing of wide heat radiation.
Summary of the invention
The object of the present invention is to provide a kind of wide sealing, to solve the technical problem that seal ring face radiating effect is poor and aging speed is fast existed in prior art.
Based on above-mentioned purpose, the invention provides a kind of axle, the sealing of face width face, hole, comprise carrier pedestal and be positioned at the seal ring face on this carrier pedestal, the sealing position of described wide sealing installs wide of circle sealing in a week, alternately drawing a bow or bending at described sealing wide middle the right and left in described seal ring face, makes the feature in described seal ring face show as: described seal ring face with the wide face of described sealing together Zhou Yuanzhi be that S is curved in launching.
Present invention also offers a kind of axle, the sealing of wide of female cone inclined-plane, comprise carrier pedestal and be positioned at the seal ring face on this carrier pedestal, the sealing position of described wide sealing installs wide of circle sealing in a week, alternately drawing a bow or bending in the large footpath limit of described seal ring face in wide of described sealing and both sides, path limit, makes the feature in described seal ring face show as: described seal ring face with the wide face of described sealing together Zhou Yuanzhi to being that to look side ways S curved in launching.
Invention further provides the sealing of wide of a kind of end face, comprise carrier pedestal and be positioned at seal ring face on this carrier pedestal, the sealing position of described wide sealing installs wide of circle sealing in a week, described seal ring face is gradually opened along the minor axis limit of wide of described sealing or section is gradually opened or Duan Kaizhi major diameter limit, received to minor axis limit by the gradually closing of major diameter limit or section gradually closing or section again, alternately open receipts, make the circle in the line of apsides in described seal ring face, and the feature in described seal ring face of circle shows as in the line of apsides: described seal ring face with the wide face of described sealing together Zhou Yuanzhi be that side-looking S is curved in launching.
To sum up, wide sealing provided by the invention, is applicable to axle, face, hole, axle, female cone inclined-plane, or end face; This wide sealing comprises carrier pedestal and is positioned at the seal ring face on described carrier pedestal, and during seal ring face is together launched along Zhou Yuan with wide of the sealing of corresponding sealing station, corresponding is that S is curved, stravismus S is curved or side-looking S is curved.
Wide sealing of the present invention, the curved S of described S is a kind of bending shape, and with the increase of sealed diameter, the S of sealing is curved can be 1 to multiple, also can repeatedly draw a bow or bending.
Wide sealing of the present invention, described S is curved, stravismus S is curved and side-looking S curved be that even curved arc S is curved; Or for adapting to different sealing demands, described S is curved, stravismus S is curved and the curved special-shaped S being angle is curved, echelon is curved, irregular arc is curved or band straight line is curved of side-looking S is curved.
In the present invention, the wide face width degree of sealing of described wide sealed width=S curved seal ring face width degree=corresponding Sealing.
Above-described wide sealing, the sealing of cone wide of inclined-plane and the sealing of wide of end face, walk a bit rear of the curved seal ring face of the S that rubs with the corresponding any point sealed on wide rotated to dispel the heat, the curved seal ring face of S is walked again a bit again with low temperature of comparing, a heat that all defocuses is dispelled the heat again, so continuously.Compare and can reduce the operating temperature of sealing, corresponding linear speed, pressure, the ageing-resistant performance improving sealing.
In the present invention, the carrier pedestal in seal ring face is pedestal (skeleton) dish (ring) pedestal; Housing, putting and establish S groove, chamfered groove, indent, is also the carrier pedestal in the curved seal ring face of this S, this pedestal groove mid-soft, hard filler or shaping filler, opens lobe filler, seal ring, and its seal ring face also can form S seal ring face.The floating ring of floating-ring seal also can be set to the curved seal ring face of non-contact S.Described seal ring face is the circle face contacting with corresponding sealing surface, rub, seal.
Wide face of the present invention is sealed into soft, hard material or composite material, and it is hard material that one of the friction pair as mechanical seal is set to the curved seal ring face of S.
This wide sealing is interactive static seal with corresponding sealing surface, can set if desired and be sealed into dynamic, corresponding sealing surface as quiet.
Sealing also can establish the curved seal ring face of the many S of consubstantiality, or and with dust excluder lips circle face.
Curved wide the sealing of this S, has liquid film tiny leakage to be inclined to, and being more suitable for needs that tiny leakage seals, the intermediate seal of unlubricated sealing or combination seal.
