Abstract
The invention discloses a kind of stretch-proof wind-powered electricity generation revolving support rubber seal, which includes fiber skeleton and rubber body, and the fiber skeleton, which runs through, to be arranged in rubber body, and fiber skeleton is one of aramid line, vinylon thread, polyester line；The rubber body is made of nitrile rubber.The present invention uses preforming process, and fiber skeleton is fixed on specific position in rubber, fixes frame position；It, by the way that fiber skeleton is added, improves product and resists the extraneous performance stretched, reduce the stress in installation process, improve the service life of sealing ring under the premise of not changing product size.
Description
Technical field
The invention belongs to rubber seal fields, and in particular to a kind of stretch-proof wind-powered electricity generation revolving support rubber seal.
Background technique
In wind-powered electricity generation industry, the service life of yaw and pitch variable bearings directly influences the generating efficiency of complete machine, due to yaw
And pitch variable bearings, all in high-altitude, scene replacement difficulty is big, and high labor cost, leakage rouge caused by the failure of sealing ring greatly increases
Blower O&M cost.
In order to improve the service life of bearing, reduce the frequency of replacement sealing ring, sealing producer to the material of sealing ring into
It has gone research, has improved the performances such as the resistance to ozone of material, resistance to ultraviolet, 100% stretching strength, hardness, and specific by being added
Material reduces the coefficient of friction of rubber.Bearing producer also attempts the service life that bearing is improved by change bearing arrangement,
Corresponding ring structure is also required to change, but this method higher cost.
In addition, becoming MW class by original multikilowatt, bearing size is increasing, right with the development of wind-powered electricity generation industry
The bearing capacity requirement of sealing ring is higher and higher, since yaw bearing and pitch variable bearings rubber seal are all pure plastic structures,
Exoskeletal enhancing, rubber belong to elastomer, and can be stretched 30%-200%, there is the phenomenon that stretching, peace during the installation process
It being not easy to find after dress, if being in stress after sealing ring installation, it will the service life for substantially reducing sealing ring causes to leak rouge,
The problems such as bearing wear.
Summary of the invention
The object of the present invention is to provide a kind of stretch-proof wind-powered electricity generation revolving support rubber seal, reduce in installation process
Stress improves the service life of sealing ring.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of stretch-proof wind-powered electricity generation revolving support rubber seal, the rubber seal include fiber skeleton and rubber sheet
Body, the fiber skeleton, which runs through, to be arranged in rubber body, and fiber skeleton is one of aramid line, vinylon thread, polyester line.
Further, the rubber body is made of nitrile rubber.
Further, the fiber skeleton uses polyester line, and the line footpath of polyester line is 0.38-0.42mm.
Further, the fiber skeleton uses polyester line, and the line footpath of polyester line is 0.4-0.45mm.
Further, the fiber skeleton uses vinylon thread, and the line footpath of vinylon thread is 0.58-0.60mm.
Further, the fiber skeleton uses aramid line, and the line footpath of aramid line is 0.5-0.52mm.
Compared with prior art, beneficial effects of the present invention: preforming process is used, fiber is fixed on specific in rubber
Position fixes fiber line position.Under the premise of not changing product size, by the way that fiber skeleton is added, improves product and support
The anti-extraneous performance stretched, reduces the stress in installation process, improves the service life of sealing ring.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of rubber seal in the present invention.
Fig. 2 is to squeeze out external mold schematic diagram.
In figure: 1 is fiber skeleton (one of aramid line, vinylon thread, polyester line), and 2 be rubber.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of stretch-proof wind-powered electricity generation revolving support rubber seal, which includes fiber skeleton
And rubber body, the fiber skeleton, which runs through, to be arranged in rubber body, and fiber skeleton is aramid line, vinylon thread, polyester line
One of, rubber body is nitrile rubber.
The performance indicator of several fiber lines is listed in table 1
1 fiber skeleton performance indicator of table
The application performance index of several fiber lines is listed in table 2
2 embodiment of table
The production method of this rubber seal are as follows: extruder usesIt squeezes out, it is long through than for 1:20, extruder temperature 55
DEG C, 1 temperature of machine barrel is 60 DEG C, and machine barrel 2 is 70 DEG C, and head temperature is 70 DEG C.The hole of one diameter 1mm of processing, fine among machine core
Dimension skeleton is combined to together by the hole of machine core with rubber, finally by squeezing out external mold, is finally combined to and is made preforming together
Adhesive tape, fiber skeleton be it is single, squeeze out external mold shape be Y shape (see Fig. 2), position of the fiber skeleton in rubber compound is fixed
's.Preforming adhesive tape is put into 2 meters of long sulfurizing moulds and is vulcanized, stretch-proof rubber is made using continuous mould pressing vulcanization
Glue sealing ring.
The basic principles, main features and advantages of the invention have been shown and described above.Those skilled in the art
It should be appreciated that the protection scope that the above embodiments do not limit the invention in any form, all to be obtained using modes such as equivalent replacements
The technical solution obtained, falls in protection scope of the present invention.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
