Description
Art
It the utility model is related to a kind of crusher shaft bearing sealing device, the crushing teeth that the kibbler roll that is particularly suitable for use in uses
Roller, belong to disintegrating apparatus technical field.
Background technology
Toothed roll crusher is a kind of important coal separation, preparation equipment, and the throat in process system is therein broken
Broken discaling roll is in the course of the work, severe by strong shock loading, working environment；Often there is broken material dust and enter axle
Inner chamber is held, pollutes the grease of intracavitary, shortens the service life of bearing, while ring wear is serious, short life.
The sealing of discaling roll bearing is dynamic sealing, and working environment dust is more, and sealing difficulty is big；Existing bearing seal structure
Have：Hair felt-ring seal, skeleton oil seal, packing seal, labyrinth seal, O-ring sealing etc., some is using the double of combining form
Sealing structure；Existing subject matter：Sealing effectiveness is poor, sealing ring short life.In the prior art, the use that bearing seal has compared with
Complicated structure, its replacing are extremely difficult.There is presently no paired outwardly using bag skeleton rotary shaft lip seal in secondary lip
Installation, while the three seal structures combined with labyrinth shaped seal；Particularly apply in toothed roll crusher, it is special to play
Sealing function.
The content of the invention
The purpose of this utility model is in place of overcome the deficiencies in the prior art, there is provided a kind of good seal performance, is easy to more
The roll breaker fluted roller associated sealing arrangement for bearings changed.
Roll crushing discaling roll associated sealing arrangement for bearings described in the utility model, mainly by discaling roll axle 1, axle sleeve 2, sealing ring 3,
Seal the compositions such as transparent cover I 4, screw 5, bearing holder (housing, cover) 6, bearing 7, sealing transparent cover II 8, labyrinth 9.
It is characterized in that：The outer ring of bearing 7 is wrapped up by bearing holder (housing, cover) 6, and bearing inner race is positioned at the shaft shoulder of discaling roll axle 1 by axle sleeve 2, and two
Side is provided with sealing transparent cover I 4, sealing transparent cover II 8, is fixed as one respectively with bearing holder (housing, cover) 6 by screw 5, together with bearing outer ring
Rotate, and protect bearing；Sealing transparent cover I 4, the sealing center portion of transparent cover II 8 are provided with paired sealing ring 3, by its auxiliary lip and axle sleeve 2,
Labyrinth 9 forms dynamic sealing, prevents dust from entering bearing cavity；(working end) is in crusher body inner chamber on the right side of bearing, makees
Industry environment is more severe, sets up labyrinth 9, is coordinated by three bow-shaped recess and realize labyrinth seal, the axial direction of bow-shaped recess installation
Gap b is 1~2.5mm, and radially unilateral gap c is 0.5~2mm；And groove cavities are full of lubricating grease.
Described bearing holder (housing, cover) 6 is connected separable assembled with sealing transparent cover I, sealing transparent cover II by screw 5, simple in construction, is easy to
Change.
For described sealing ring 3 using there is bag skeleton rotary shaft lip seal in secondary lip, its material uses nitrile rubber.
The lip set direction of sealing ring 3：Oil-leakage-prevention, just inwardly；Dust protection, just outwardly.With reference to disintegrating machine use environment, lip
Mouth direction outwardly, prevents material dust from entering bearing bore in pairs, avoids grease pollution, improves sealing property, extending sealing ring makes
With the life-span, bearing service life also ensure that.
This is using new innovative technology：Arch labyrinth seal is set up in the lip direction of sealing ring 3 outwardly using paired,
Labyrinth inner chamber is full of grease simultaneously, and three seals effectively combine, and realizes the sealing property under special operation condition, extends sealing ring 3
Service life.
The beneficial effects of the utility model：Good seal performance, sealing ring long lifespan；It is simple in construction, it is conveniently replaceable.
