Abstract
The present invention provides a kind of Vertical Mill load cylinder piston rod packing mechanism, and its main points is：It is made up of successively dust ring, the first copper sheathing, a V shape sealing rings group, main copper sheathing, the 2nd V shape sealing rings group and the second copper sheathing from outside to inside from piston rod upper end；The main copper sheathing is, its expanded view is in horizontal banding, uniform several holes with band, the rule in uniform several holes is with band, all well is divided into two kinds of row, and one is classified as three holes of genesis analysis, another to be classified as four holes of genesis analysis, two arrange alternate arrangement from left to right, and graphite is filled in each hole.The positive effect of the present invention is：Initial lubricity is good.After main copper sheathing is filled with kollag, the surface of main copper sheathing can form relatively low friction pair under initial operating mode, reduce its abrasion with piston rod.
Description
Technical field
The present invention relates to a kind of Vertical Mill load cylinder, specifically Vertical Mill load cylinder piston rod packing mechanism.
Background technology
Vertical Mill load cylinder is most important execution unit in the hydraulic system of vertical mill for manufacture cement, and its tiltably-mounted is in machine
In frame, power is finally transmitted to main frame grinding roller with rocking arm hinge-coupled and by rocking arm.Vertical Mill load cylinder is in outdoor operation work
Make and use environment is severe, major influence factors include:Low frequency, high intensity vibrations, high-impact and dust etc., so oil cylinder is lived
The sealing structure of stopper rod has significant impact to the oil cylinder life-span, sealing structure need to have bearing capacity high, impact resistance, high temperature resistant,
The features such as self-lubricating capacities are strong.
Current oil cylinder piston rod seal structure is from outside to inside by dust ring, the first copper sheathing, a V shape sealing ring groups（See CN
202867846 U）, the copper sheathing with oil groove, the 2nd V shape sealing rings group and the second copper sheathing constitute successively.Its defect is：1. it is initial
Poor lubricity.Under initial operating mode, the copper sheathing abrasion of band oil groove is heavier, and the dirt in fluid is easily saved bit by bit after abrasion, and then aggravates
The abrasion of piston rod；2. in dry-type encapsulated environment, it is close that load cylinder epicoele fluid flow to a V shapes by band oil groove copper sheathing
The fluid of seal group is less, therefore reduces the using effect of a V shape sealing ring groups；3. axial thrust is big.In axial unbalance loading
In the case of, band oil groove copper bush lubrication is uneven, there is the situation with piston rod locking, and then occur what shaft end gland was ejected
Phenomenon；4. stain resistance is poor.By long-term use, external dust can penetrate into band oil groove copper sheathing by piston rod, deposit copper sheathing
The abrasion of piston rod can be aggravated behind surface；5. use cost is high.It is close with V shapes when piston rod can be aggravated after the abrasion of band oil groove copper sheathing
The abrasion of seal group, causes part life to reduce, and increases frequency of maintenance and use cost.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of Vertical Mill load cylinder piston rod packing mechanism.
The object of the present invention is achieved like this：From piston rod upper end from outside to inside by dust ring, the first copper sheathing, first
V shape sealing rings group, main copper sheathing, the 2nd V shape sealing rings group and the second copper sheathing are constituted successively；The main copper sheathing is, its expansion
Figure is in horizontal banding, uniform several holes, the filled solid lubricant in each hole with band.
Compared with prior art, the positive effect of the present invention is：
1st, initial lubricity is good.After main copper sheathing is filled with kollag, the surface of main copper sheathing can be formed under initial operating mode
Relatively low friction pair, reduces its abrasion with piston rod；
2nd, under wet-sealed environment, the fluid of load cylinder epicoele can on a small quantity infiltrate into a V shapes close by main copper sheathing
Seal group, therefore improve the using effect of sealing group；
3rd, axial thrust is small.In the case of axial unbalance loading, because the kollag of main copper sheathing insertion possesses self-lubricating property, keep away
Exempt from because of its situation with piston rod locking when oil lubrication is uneven；
4th, stain resistance is strong.The kollag of main copper sheathing insertion possesses certain adsorptivity, can absorb part from load cylinder
The dust that outside is penetrated into, reduces friction；
5th, use cost is low.The increase of main copper sheathing service life can simultaneously improve the service life of piston rod v-seal part.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is schematic diagram of the invention.
Fig. 2 is the expanded view of main copper sheathing.
Specific embodiment
Referring to Fig. 1, from the upper end of piston rod 1 from outside to inside by dust ring 2, the first copper sheathing 3, a V shape sealing rings group 4,
Main copper sheathing 5, the 2nd V shape sealing rings group 6 and the second copper sheathing 7 are constituted successively；Referring to Fig. 2, the main copper sheathing is, its expanded view
In horizontal banding, uniform several holes 52 on band body 51, the rule of whole pore size distributions is that all well is divided into two kinds of row, a row
It is three holes of genesis analysis, another to be classified as four holes of genesis analysis, two arrange alternate arrangement, the filled stone in each hole from left to right
Ink.
Claims (2)
1. a kind of Vertical Mill load cylinder piston rod packing mechanism, it is characterized in that：From piston rod upper end from outside to inside by dust-proof
Circle, the first copper sheathing, a V shape sealing rings group, main copper sheathing, the 2nd V shape sealing rings group and the second copper sheathing are constituted successively；The master
Copper sheathing is that its expanded view is in horizontal banding, uniform several holes, the filled solid lubricant in each hole with band.
2. according to the Vertical Mill load cylinder piston rod packing mechanism described in claim 1, it is characterized in that：It is uniform some with band
