Abstract
The utility model discloses a primary cup relates to cylinder sealing technical field, including the skin bowl body who is the round, this skin bowl body's sealing edge locates to closed angle or fillet, skin bowl body is equipped with the wear -resisting sealing washer of multichannel with cylinder internal contact department, is equipped with a plurality of fixed orificess with hinge joint on this skin bowl body. This primary cup can improve the life of product greatly, has increased the availability factor that overturns certainly, has reduced the manufacturing cost of mining company.
Description
Technical field
This utility model is related to cylinder seal technical field, more particularly to a kind of sealing cup.
Background technology
KF60 tons, from track transport vehicle is turned in the large-scale mining site such as colliery iron mine using very wide, are earliest to produce for 1964, existing
It is being widely used in mining transport.The pattern of side dump wagon cylinder seal is also used till today always at that time certainly,
Far behind existing service condition, current service life is short, and universal is accomplished by replacing less than half a year.
The content of the invention
In place of in order to overcome the above-mentioned deficiencies of the prior art, this utility model provides a kind of sealing cup, the sealing cup
The service life of product can be greatly improved, the service efficiency of side dump wagon is increased, the production cost of mining company is reduced.
For achieving the above object, this utility model is adopted the following technical scheme that：A kind of sealing cup, including the skin in round
Bowl body, is wedge angle or fillet at the seal lip of the leather cup body, and the leather cup body is provided with multiple tracks with cylinder inner joint
Wear-resistant seal circle, the leather cup body is provided with the multiple fixing holes being connected with piston.
In above-mentioned technical proposal, the wear-resistant seal circle is at least together, and the wear-resistant seal circle protrusion leather cup body
2-4mm。
In above-mentioned technical proposal, the fixing hole is circular or oval.
In above-mentioned technical proposal, the leather cup is originally provided with vivo reinforcement compensation cloth, and the reinforcement compensation cloth is resistance to from highest
Fixing hole midline is extended at mill sealing ring, the reinforcement compensation cloth is at least one layer.
In above-mentioned technical proposal, the reinforcement compensation cloth of the leather cup body root is compensated than the reinforcement at wear-resistant seal circle
At least two-layer more than cloth.
The beneficial effects of the utility model are：Wear-resistant seal circle loads and formed after cylinder depression, and seal lip is close with wear-resisting
Oil storage tank is formed between seal, extends lubricant effect, reduce abrasion, greatly improve the service life of product, it is not necessary to which Jing is often more
Sealing cup is changed, production cost is reduced；Wear-resistant seal circle can play effect of the absorption on cylinder inner wall, good sealing effect, and
And the abrasion of the 2-4mm of cylinder inner wall can be compensated, improve the service efficiency of side dump wagon；Reinforcement compensation cloth is increased, is improve close
Envelope lip and the elasticity of wear-resistant seal circle, strengthen sealing effectiveness.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A views in Fig. 1.
Wherein：1. leather cup body, 2. seal lip, 3. wear-resistant seal circle, 4. strengthens compensation cloth, 5. fixing hole.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of sealing cup as depicted in figs. 1 and 2, including the leather cup body 1 in round, the sealing of the leather cup body 1
It is wedge angle or fillet at lip 2, the leather cup body 1 is provided with multiple tracks wear-resistant seal circle 3 with cylinder inner joint, the leather cup body
1 is provided with the multiple fixing holes 5 being connected with piston.
In above-mentioned technical proposal, the wear-resistant seal circle 3 is at least together, and the protrusion leather cup sheet of wear-resistant seal circle 3
Body 2-4mm.
In above-mentioned technical proposal, the fixing hole 5 is circular or oval.
In above-mentioned technical proposal, reinforcement compensation cloth 4 is provided with the leather cup body 1, the reinforcement compensates cloth 4 from highest
The midline of fixing hole 5 is extended at wear-resistant seal circle 3, the reinforcement compensation cloth 4 is at least one layer.
In above-mentioned technical proposal, the reinforcement compensation cloth 4 of the root of leather cup body 1 is than the reinforcement at wear-resistant seal circle 3
Compensation cloth more than 4 at least two-layer.It is softer when temperature influence, sealing cup body summer, it is harder when winter, because
This, increases the number of plies of the reinforcement compensation cloth 4 of the root of leather cup body 1 so that the shore hardness of the root of leather cup body 1 is more than leather cup sheet
Hardness at the wear-resistant seal circle 3 of body 1, is unlikely to deform so as to sealing cup is assemblied on piston bush, prevents eccentric phenomena,
A lateral wearing is prevented, the service life of leather cup is extended.
3 times of product before the sealing cup use time substantially thing, use time was more than 18 months.Avoid Jing normal
Sealing cup is changed, the labor intensity of workman is reduced.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
This is confined to, any those familiar with the art can readily occur in the technical scope that this utility model is disclosed
Change or replacement, all should cover within protection domain of the present utility model.
