Abstract
The utility model discloses a kind of hydraulic cylinder cylinder composite dust-proof circles, dirty ring is received including wiper of rubber and hard, the two constitutes a kind of composite dust-proof circle being composed of wiper of rubber and dirty ring of receiving, the composite dust-proof circle left side is wiper of rubber, and hard receives dirty ring and is embedded in wiper of rubber on the right；The composite dust-proof circle is mounted on the cylinder body outermost layer by tailpiece of the piston rod, and inner cavity coordinates with piston rod, and outer wall is embedded in cylinder body.The hydraulic cylinder cylinder composite dust-proof circle has the characteristics that simple in structure, making is low with maintenance cost, easy to use, reliable efficient.
Description
Technical field
The utility model is related to the dustbands of axially directed bar, plunger, piston rod for hydraulic cylinder and cylinder, specifically relate to
And a kind of hydraulic cylinder cylinder composite dust-proof circle.
Background technology
In the use environment of oil cylinder or cylinder difference, inevitably oil cylinder or gas are influenced by the pollution of extraneous " dirt "
The service life of cylinder, these " dirts " include dust, sand-lime, rainwater, frost, contaminated oils and corrosive particles etc..For
It prevents the external dirt especially corrosive particles object from entering inside sealing mechanism, the longevity is used with protect guide elements and sealing element
Life generally uses simple and practical dustband, can be divided into two class of single-acting and double acting by its function at present；By its dustproof element
Construction can be divided into two kinds of single lip and lips；It can be divided into homogenous material, rubber armouring, composite dust-proof circle, homogenous material master by material
There are rubber, plastics, a metal, rubber armouring is compound mainly with one or more of materials mainly based on metallic framework dustband
Two or more elements of material manufacture are composed；Dust-proof is all mainly to play dust-proof effect by lip low friction.
Invention content
The purpose of this utility model be to provide it is a kind of it is simple in structure, make it is low with maintenance cost, easy to use, reliable efficient
A kind of hydraulic cylinder cylinder composite dust-proof circle.
In order to achieve the above object, a kind of hydraulic cylinder cylinder composite dust-proof circle of the utility model includes wiper of rubber and hard
Receive dirty ring, the two constitutes a kind of composite dust-proof circle being composed of wiper of rubber and dirty ring of receiving, the composite dust-proof circle left side
It is wiper of rubber, hard receives dirty ring and is embedded in wiper of rubber on the right；The composite dust-proof circle is mounted on by tailpiece of the piston rod
Cylinder body outermost layer, inner cavity coordinate with piston rod, and outer wall is embedded in cylinder body.
Above-mentioned hydraulic cylinder cylinder composite dust-proof circle increases hard and receives under original single wiper of rubber function
Dirty ring constitutes and a kind of receiving the compound dustband that dirty ring is composed by wiper of rubber and hard.Due to the material of two elements
Material is different with hardness, also different to dust-proof effect.When wiper of rubber is damaged by hard object, it is dust-proof to depend merely on rubber material
The dust-proof effect of circle has greatly reduced, and increased hard receives dirty ring and plays the role of second class protection at this time, since this receives dirty ring material
Matter hardness plays a good role compared with wiper of rubber height to preventing the hard object of particle from entering inside cylinder seal part.
Description of the drawings
Fig. 1 is a kind of hydraulic cylinder cylinder composite dust-proof circle main cross section structure diagram of the utility model.
Fig. 2 is a kind of hydraulic cylinder cylinder composite dust-proof circle installation condition structural schematic diagram of the utility model.
Reference numeral：Wiper of rubber 1 receives dirty ring 2, primary seal 3, cylinder body 4, support ring 5, piston rod 6.
Specific implementation mode
A kind of hydraulic cylinder cylinder composite dust-proof circle of the utility model is made into one below in conjunction with the drawings and specific embodiments
Step is described in detail.
Shown in Fig. 1, a kind of hydraulic cylinder cylinder composite dust-proof circle of the utility model includes wiper of rubber 1 and hard receives dirty ring
2, a kind of composite dust-proof circle being composed of wiper of rubber 1 and dirty ring 2 of receiving is constituted, which is that rubber is anti-
Konisphere 1, dirty ring 2 of receiving are embedded in wiper of rubber 1 on the right；The composite dust-proof circle be mounted on by tailpiece of the piston rod cylinder body 4 most
Outer layer, inner cavity coordinate with piston rod 6, and outer wall is embedded in cylinder body 4.
The application method of the utility model hydraulic cylinder cylinder composite dust-proof circle is consistent with common dustband, that is, is directly loadable into oil
Cylinder outermost layer, as shown in Figure 2.In the oil cylinder or cylinder of linear motion, the place of stretching or the retraction of axis is most easy to pollute, compound
The secondary dust-proof cleaning effect to oil cylinder or cylinder inner cavity of dustband is considerably improved.When the long-term dirt product in axis extending area
Poly-, the dirt on axis becomes hard and adsorption capacity is big, when oil cylinder or Telescopic-cylinder work, pollutes hard object and easily penetrates wiper of rubber
1 and enter cylinder cavity, cause seriously to pollute, after polluting hard object and penetrating wiper of rubber 1, the utility model hydraulic cylinder cylinder
The hard of composite dust-proof circle receive dirty ring 2 just play again blocking dirt enter, play effect dust-proof again.
