Abstract
The utility model is related to a kind of graphite grazing structures, including rotor, sealed track, graphite annulus, seal assembly, shell, sealed track be mounted on the rotor and with rotor synchronous rotary, rotor is mounted on by bearing on shell, seal assembly includes graphite annulus mounting base, bushing, waveform spring, and bushing is mounted on shell, and graphite annulus is mounted in graphite annulus mounting base, and contacted with sealed track end, it is provided with waveform spring between graphite annulus mounting base and bushing.The utility model ensure that the reliability of dynamic sealing, avoid the oil leakage fault caused by the abrasion of sealing element by the way that waveform spring is arranged.
Description
Technical field
The utility model is related to a kind of sealing structure, especially a kind of graphite grazing structure is realized and is realized in high speed shaft end
Sealing lubricating-oil prevents lubricating oil from leaking.
Background technology
In transmission mechanism operation process, lubricating oil effect is important, can both lubricate revolute pair, avoid the unlubricated friction of revolute pair
It wipes；Most of heat can be taken away in cyclic process again, parts is avoided to lead to burn or locking etc. since heat is excessively high
Situation.But oil leakage fault frequent occurrence in transmission mechanism, situations such as causing transmission mechanism to fail, prevent lubricating oil leakage from becoming
The key that solves the problems, such as.Seal type type is various, and by between sealing surface, whether relative motion is divided into static seal and dynamic sealing.It is dynamic
In sealing, it is divided into rotary seal and reciprocation sealing by the relative motion mode of containment member, wherein dynamic sealing is due to being in sound
It is sealed between component, the abrasion that can cause obturator is used for a long time, to make the gap between sound component become larger, from
And generate oil leakage fault.
Invention content
The purpose of this utility model is to provide a kind of graphite grazing structure, may be implemented movable sealing structure be sealed into,
Will not because can sealing element abrasion caused by oil leakage fault.
The specific technical solution of the utility model is that graphite grazing structure includes rotor, sealed track, graphite annulus, sealing
Component, shell, sealed track be mounted on the rotor and with rotor synchronous rotary, rotor by bearing be mounted on shell on, sealing
Component includes graphite annulus mounting base, bushing, waveform spring, and bushing is mounted on shell, and graphite annulus is mounted on graphite annulus mounting base
On, and contacted with sealed track end, it is provided with waveform spring between graphite annulus mounting base and bushing.The sealed track with
Sealing ring is both provided between rotor and between bushing and shell.
The graphite annulus of the utility model uses integral form, is contacted with the sealed track end being mounted on the rotor, and constitutes
Primary seal Interface limits are axially revealed；Graphite annulus is pushed against sealed track end by the waveform spring being compressed axially being arranged, when
When mechanism is run, sealed track makes graphite main loop be pressed against always close with graphite annulus long term wear due to the effect of waveform spring
It seals on runway, to compensate for wear extent, ensure that the gap between sound.The utility model is protected by the way that waveform spring is arranged
The reliability for having demonstrate,proved dynamic sealing avoids the oil leakage fault caused by the abrasion of sealing element.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown, graphite grazing structure includes rotor 1, sealed track 2, graphite annulus 3, seal assembly, shell 4, sealing
Runway 2 be mounted on rotor 1 on and with 1 synchronous rotary of rotor, rotor 1 by bearing be mounted on shell 4 on, seal assembly includes stone
Black ring mounting base 5, bushing 6, waveform spring 7, bushing 6 are mounted on shell 4, and graphite annulus 3 is mounted in graphite annulus mounting base 5,
And contacted with 2 end of sealed track, waveform spring 7 is provided between graphite annulus mounting base 5 and bushing 6.The sealed track 2
It is both provided with sealing ring between rotor 1 and between bushing 6 and shell 4.
