Abstract
The invention provides a method for preparing a yawing friction plate of a wind turbine generator by using aramid fiber, and the following raw materials in parts by weight are adopted in the method: 5-8 parts of bonding agent, 15-30 parts of reinforcing fiber, 12-18 parts of grinding agent, 10-23 parts of lubricant and 20-33 parts of regulating agent, wherein the bonding agent comprises one or combination of plural of phenolic resin, butyronitrile-modified phenolic resin and silicon-modified phenolic resin; the reinforcing fiber comprises one or the combination of the plural of copper cotton fiber, the aramid fiber and mineral fiber; the grinding agent comprises one or the combination of the plural of zirconium silicate, iron black, barium sulfate and calcium carbonate; the lubricant comprises one or the combination of the plural of inorganic lubricant, organic lubricant and metal sulfide; and the regulating agent comprises one or the combination of the plural of aluminum oxide and friction powder. In the method, the aramid fiber which is high in tensile strength and very good in flexibility is utilized for improving the wear resistance of friction material and the compressive strength of the material. Further, the good braking performance of the friction plate during the using process can be ensured, the service life is prolonged, and the friction noise can be eliminated.
Description
Technical field the present invention relates to new energy field, particularly the preparation method of wind driven generator yaw friction plate.
Background technology is along with development of global economy, also develop rapidly of new forms of energy industry, and wherein wind energy more and more is subjected to the attention of countries in the world as a kind of renewable energy source of cleaning, and wind energy market also develops rapidly.Aerogenerator is the power machine that wind energy is converted to mechanical energy, and what it utilized is natural energy resources, does not have fuel problem, also can not produce radiation or atmospheric pollution, has now become the emphasis of new forms of energy development.
During wind turbine power generation, need adjust the direction of blade, with the vanes fixed of aerogenerator direction, so that wind wheel obtains maximum wind energy towards the wind-force maximum because of the change of wind-force direction.Yaw system plays a part to adjust the blade of wind-driven generator direction, and the driftage friction plate is a main accessory of yaw system.Because wind-power electricity generation developed rapidly in recent years in China, the power of generator promotes to 3MW, 5MW from 0.75MW, 1.5MW, and this friction plate that just requires to go off course not only has good braking effect, and also will be arranged long work-ing life, high compression strength, no friction noise.The primary structure of driftage friction plate is cakingagent, fortifying fibre, abrasive, lubricant and necessary conditioning agent at present, the ubiquitous problem of this friction plate is that the product abrasion loss is excessive, friction noise is serious, so be not very desirable in the complete machine use.
Summary of the invention the purpose of this invention is to provide the method that a kind of aramid fiber prepares the wind driven generator yaw friction plate, the driftage friction plate of this method preparation has high strength, high-wearing feature, effectively eliminate friction noise, improve aerogenerator reliability of operation and security.
Material used in the present invention is formed as following weight percent: tackiness agent 5-8, fortifying fibre 15-30, abrasive 12-18, lubricant 10-23, conditioning agent 20-33, tackiness agent wherein comprise the one or more combination of resol, nbr modified phenolic resins, silicon modified phenolic resins; Fortifying fibre comprises the one or more combination of copper cotton fibre, aramid fiber, mineral fibre; Abrasive comprises the one or more combination of zirconium silicate, iron oxide black, barium sulfate, lime carbonate; Lubricant comprises the one or more combination of inorganic lubricant, organic lubricant, metallic sulfide; Conditioning agent is the one or more combination of aluminium sesquioxide, friction powder.
The present invention compared with prior art, its advantage is: utilize tensile strength height, the extraordinary aramid fiber of snappiness to improve the ultimate compression strength of the wear resisting property and the material of friction materials.Make friction plate in use guarantee good braking ability, improve work-ing life, eliminate friction noise.
