As a kind of preferred version of the present utility model, a kind of slow-speed of revolution rotary seal structure also includes auxiliary seal ring I and auxiliary seal ring II；Arranging groove near inner face in the inner circle of described fixing axle, the inwall of described groove is coordinated with the cylindrical sealing of rotating shaft by auxiliary seal ring I；Boss II in described shell is coordinated with the cylindrical sealing of rotating shaft by auxiliary seal ring II。
As another kind of preferred version of the present utility model, a kind of slow-speed of revolution rotary seal structure also includes annular gasket, and the inner face of described end cap is pressed on the end face of the boss I that rotating shaft cylindrical is arranged by annular gasket。
As a kind of improvement project of the present utility model, a kind of slow-speed of revolution rotary seal structure also includes O, and the inwall of described shell is coordinated with the cylindrical sealing of fixing axle by O。
Of the present utility model have the technical effect that this utility model is provided with thick seal washer, auxiliary seal ring and primary seal circle three seals according to applying working condition, thick seal washer is had in the Position Design communicated with the external world, mainly block extraneous particulate matter entrance primary seal circle it is damaged, the design of primary seal circle two ends has auxiliary seal ring, can effectively reduce internal high pressure liquid infiltration out after pressure, thus increasing the sealing effectiveness of primary seal circle；Primary seal circle can be adjusted pretension amount by the gap between flange and the end face of shell on fixing axle, after using the abrasion of a period of time primary seal circle, only need to reduce the gap between flange and the end face of shell further can increase the magnitude of interference of primary seal circle, strengthen sealing effectiveness。
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of slow-speed of revolution rotary seal structure。
In accompanying drawing: 1 shell；2 rotating shafts；3 auxiliary seal rings I；4 auxiliary seal rings II；5 fixing axles；6 annular gaskets；7 bolts；10 primary seal circles；11 O；12 end caps；13 bolts；15 thick seal washers；16 boss I；17 boss II。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail。
As it is shown in figure 1, a kind of slow-speed of revolution rotary seal structure, including shell 1, the rotating shaft 2 of hollow structure, the fixing axle 5 of hollow structure, end cap 12, thick seal washer 15 and primary seal circle 10。Rotating shaft 2 and fixing axle 5 are coaxially set。Shell 1 is enclosed within outside rotating shaft 2 and fixing axle 5, and end cap 12 is enclosed within outside rotating shaft 2, and the inner face of end cap 12 is pressed on the end face of the boss I 16 that rotating shaft 2 cylindrical is arranged and is connected by bolt 13 with the end face of shell 1。Arranging ring flange on the cylindrical of fixing axle 5, fixing axle 5 is connected with the other end of shell 1 by ring flange and bolt 7。The inner circle of shell 1 arranges boss II 17, the end face of the boss II 17 in shell 1 by thick seal washer 15 with rotating shaft 2 outside boss I 16 other end sealing coordinate。Primary seal circle 10 is enclosed within outside rotating shaft 2 and is crushed between rotating shaft 2 and shell 1, and one end of primary seal circle 10 is corresponding with the other end of the boss II 17 in shell 1, and the other end of primary seal circle 10 is corresponding with the inner face of fixing axle 5。
Slow-speed of revolution rotary seal structure also includes auxiliary seal ring I 3, auxiliary seal ring II 4, annular gasket 6 and O 11。Arranging groove near inner face in the inner circle of fixing axle 5, the inwall of groove is coordinated with the cylindrical sealing of rotating shaft 2 by auxiliary seal ring I 3。Boss II 17 in shell 1 is coordinated with the cylindrical sealing of rotating shaft 2 by auxiliary seal ring II 4。The inner face of end cap 12 is pressed on the end face of the boss I 16 that rotating shaft 2 cylindrical is arranged by annular gasket 6。The inwall of shell 1 is coordinated with the cylindrical sealing of fixing axle 5 by O 11。
