Abstract
The invention discloses a kind of lightweight, the manufacturing process of the wind-force off-course brake with noise abatement comprising following steps：S1, cylinder body inserts outer surface is handled, keeps its coarse；S2, Sandwich materials are engraved as predetermined shape using engraving machine；S3, epoxy glue, the unidirectional basalt fibre prepreg of package are coated in insert surface；S4, Sandwich materials are laid in the cylinder body insert surface for being wrapped basalt fibre prepreg；S5, in the Sandwich materials surface unidirectional basalt fibre prepreg of laying again, then in surface laying twill formula basalt fibre prepreg cloth, form precast body；S6, step S5 precast body is put into mold, molding was placed in press in 2-5 hour of 120-200 DEG C of pressing.The present invention uses mould pressing process：With PVC, PET, PMI, PU etc. for Sandwich materials, basalt fibre is reinforcement, is embedded in cylinder body.Light weight is prepared, with the off-course brake of noise-absorbing function through mould pressing process.
Description
Technical field
A kind of wind-force off-course brake the present invention relates to lightweight, with noise abatement.
Background technique
With the progress and development of economic society, wind-power electricity generation is endless with its resource, low in cost, convenient for utilizing, becomes
Technology is most mature in renewable new energy source utilization at present, exploit condition on the largest scale, the good generation mode of development prospect.Wind-force hair
Electricity, which has begun from " the supplement energy " to " the strategy alternatives energy " direction, to be changed.
With the wind direction in the Variable Wind Field of season or weather be it is continually changing, in order to effectively utilize wind energy, wind
The blade of machine needs the moment to be directed at wind direction, specially devises yawing brake system in wind-driven generator thus.Yawing brake system
Main function there are two：One of them is the variation for making wind power generating set box haul, always in state windward, sufficiently benefit
With wind energy, generating efficiency is improved；The other is necessary braking moment is provided, to ensure the safe operation of wind power generating set.
The off-course brake installed on blower at present is all metal material, and weight reaches several hundred kilograms, with more than ten of bolt, each bolt
Screw-down torque is up to thousands of NM, and space very little in the cabin of blower, it is difficult to replace.
Wind-driven generator degree domestic constantly expanded in recent years, but since there are also a spacings with advanced international standard
From domestic wind-driven generator noise problem gradually displays.Nearby resident generates noise to generating set for wind power plant
It complains more and more.It is generated when a part of fan noise is just worked by off-course brake.Therefore off-course brake work is solved
Noise when making is also the technical issues of wind-powered electricity generation industry development must solve.
Summary of the invention
To solve defect of the existing technology, the present invention provides a kind of by basalt continuous fiber prepreg, sandwich material
Material and brake cylinder casing inserts are compound, are prepared into high-strength light using mould pressing process, the high-performance with excellent noise-absorbing function yaws
Brake,.
A kind of lightweight, wind-force off-course brake with noise abatement manufacturing process comprising following steps：
S1, cylinder body inserts outer surface is handled, keeps its coarse；
S2, Sandwich materials are engraved as predetermined shape using engraving machine；
S3, epoxy glue, the unidirectional basalt fibre prepreg of package are coated in insert surface；
S4, Sandwich materials are laid in the cylinder body insert surface for being wrapped basalt fibre prepreg；
S5, in the Sandwich materials surface unidirectional basalt fibre prepreg of laying again, then in surface laying twill formula basalt
Fiber prepreg forms precast body；
S6, step S5 precast body is put into mold, molding was placed in press in 2-5 hour of 120-200 DEG C of pressing.
Further, in step S3, the angle of unidirectional basalt fibre prepreg is wrapped up as one in 0 °, 45 ° or 90 °
Kind is several.
Further, in step S5, the unidirectional basalt fibre prepreg of laying, angle is one in 0 °, 45 ° or 90 °
Kind is several.
Further, the Sandwich materials are one or more of PVC, PET, PMI, PU.
Further, the thickness of basalt fibre prepreg is between 0.05-5mm.
Beneficial effect：
The present invention is difficult to installation and replacement for existing metal off-course brake quality again, and noise is larger when brake operation
The defects of.The present invention uses mould pressing process：With PVC, PET, PMI, PU etc. for Sandwich materials, basalt fibre is reinforcement, embedding
Enter cylinder body.Light weight is prepared, with the off-course brake of noise-absorbing function through mould pressing process.
Sandwich materials are that the foams such as PVC, PET, PMI, PU mitigate the quality of brake significantly, and the gap in foam has
Good noise-absorbing function.
The present invention uses green material basalt fibre, which melted at high temperature by single basalt ore
Wire drawing produces after change, and product and production process are all nontoxic, are real green product, China's basalt ore
It is abundant, lower cost for material.
Specific embodiment
