Pit and lubricating cup installation screwed hole, the sealing frame include upper sealing frame and lower sealing frame, upper sealing frame and lower sealing frame difference
It is welded on the steel plate at bearing cap and bearing block；The regulation retaining mechanism includes regulating bolt, locking nut and top plate, pushes up
Successively in the seal groove of indentation sealing frame, top plate and sealing strip open the light in the corresponding position of lubricating cup installation screwed hole for plate and sealing strip
Hole, lubricating cup are installed screwed hole by lubricating cup and fixed；The regulating bolt and locking nut are arranged in the screwed hole of sealing frame, are led to
The position for being threaded in or out adjusting top plate to regulating bolt is crossed so as to be adjusted to the position of sealing strip；The sealing strip
Lubricating grease is full of in bar seam.
Described regulating bolt is screw bolt.
The top plate is made up of sheet metal.
Beneficial effect：The utility model is simple in construction, easy to process, easy to adjust, and long-term use can also keep good
Sealing state, equipment operational reliability is improved, reduce maintenance cost, improve product competitiveness.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is diagrammatic cross-section at lubricating cup of the present utility model；
Fig. 3 is diagrammatic cross-section at regulation locking mechanism of the present utility model.
In figure：1 sealing strip, 2 sealing frames, 3 top plates, 4 lubricating cups, 5 regulating bolts, 6 locking nuts, 7 steel plates, 8 diameters of axle.
Embodiment
Below in conjunction with the accompanying drawings and embodiment specifically describes to the utility model.
Fig. 1 show structural representation of the present utility model.
The utility model includes sealing strip 1, sealing frame 2, top plate 3, lubricating cup 4 and regulation retaining mechanism.
The sealing frame 2 includes upper sealing frame and lower sealing frame, and upper sealing frame and lower sealing frame are respectively welded at bearing cap
On the steel plate 7 at bearing block.
The sealing frame 2 is provided with seal groove and multiple equally distributed screwed holes and lubricating cup installation screwed hole, its quantity
Depending on journal diameter Ф.
The regulation retaining mechanism includes regulating bolt 5, locking nut 6 and top plate 3.
Described regulating bolt 5 is screw bolt.
The top plate 3 is made up of sheet metal.
Fig. 2 show diagrammatic cross-section at lubricating cup of the present utility model.
Successively in the seal groove of indentation sealing frame 2, top plate 3 and sealing strip 1 are installed in lubricating cup for shown top plate 3 and sealing strip 1
The corresponding position of screwed hole is opened the light hole, and lubricating cup 4 is installed screwed hole by lubricating cup and fixed.
The lubricating cup 4 uses national standard part, can be to dress by lubricating cup 4 when lubricating grease, which consumes, influences sealing effectiveness
The sealing adjustment structure injection lubricating grease prepared.
Fig. 3 show diagrammatic cross-section at regulation locking mechanism of the present utility model.
The regulating bolt 5 and locking nut 6 are arranged in the screwed hole of sealing frame 2, pass through being screwed into regulating bolt 5
Or back-out the position of adjustment top plate 3 so as to be adjusted to the position of sealing strip 1.
Regulating bolt 5 can be screwed into when the contact surface of sealing strip 1 and axle journal wears, and influences sealing effectiveness.
Caused vibrations, which loosen regulating bolt 5, in equipment running process influences sealing effectiveness, tightens locking nut 6, can
To play locking effect.
Process and application method of the present utility model：
First, upper sealing frame and lower sealing frame are welded on the steel plate 7 of bearing cap and bearing block, according still further to drawing
Seal groove, screwed hole and lubricating cup installation screwed hole are processed to sealing frame 2, screwed hole and lubricating cup installation screwed hole are uniformly arranged, welded
Post-processing is to prevent from deforming；
Secondly, sealing strip 1 opens the light hole relevant position at the lubricating cup installation screwed hole of sealing frame 2, and in the installation diameter of axle 8
During bearing portion, lubricating grease is filled up in the bar seam of sealing strip 1；
Again, by the seal groove of 3 indentation sealing frame of top plate 2, then the sealing strip 1 for filling up lubricating grease is pressed into the seal groove
It is interior, pay attention to the lubricating cup installation screwed hole of sealing frame 2 and top plate 3 and the unthreaded hole of sealing strip 1 when top plate 3 and sealing strip 1 are installed
Place is corresponding；
Finally, sealing strip 1 is adjusted to by correct position by regulating bolt 5, plays good sealing state, and tighten lock
Tight nut 6 is locked.
When sealing strip 1 wears, when influenceing sealing effectiveness, regulating bolt 5 is adjusted, sealing effectiveness is transferred to optimal shape
State.
The utility model is simple in construction, easy to process, easy to adjust, and long-term use can also keep good sealing state,
Equipment operational reliability is improved, reduces maintenance cost, improves product competitiveness.
The utility model the embodiment above, is merely illustrative, be not it is only, it is all in the scope of the utility model
Or the change in equivalent the scope of the utility model is surrounded by the utility model.
