Abstract
The utility model provides an angle that wind turbine generator system friction disc of yawing, characterized by goes up the dust exhaust groove of shearing of leaving the wide 5mm of dark 3mm according to the steel backing size at the plain noodles of the original friction disc steel backing face of bonding, and circular motion is followed to this groove and friction disk tangential direction chooses 30 <= alpha <= 60 according to the brake disc diameter. This kind of wind turbine generator system friction disc of yawing has guaranteed the shear strength of brake block steel backing with friction material, the steel backing intensity of brake block can not be consequently influenced, experimental identification improves more than the shear strength 40% of wind -powered electricity generation driftage friction disc, and yaw the friction disc at the during operation, the dust is discharged with the help of the rotation of friction disk along the fluting direction smoothly, thereby the vibration of driftage system has been reduced, the noise, messenger's friction surface is brought in constant renewal in, and then improvement driftage braking efficiency, can ensure the safety of the generator set, extension mechanical durability.
Description
Technical field
This utility model relates to new energy technology, particularly to new energy field wind generating set yaw friction plate.
Background technology
Wind-power electricity generation quickly grew in recent years as a kind of new forms of energy industry, the power of electromotor promotes to 3MW, 5MW, 8MW from 0.75MW, 1.5MW, the requirement of friction plate in wind power generating set has just been had higher standard by this, not only need possess good braking effect, with greater need for higher shearing strength. Current industry there is employing increase punching design on friction plate steel back and increase shear strength, as shown in Figure 1, the shear resistance of this kind of steel backing increases limited, increasing punching on steel backing, steel backing damage is relatively big, and steel backing is easily deformed, the flatness of steel backing cannot ensure, and it being unfavorable for the eliminating of friction dust so that dust is easily piled up, and overstocks in Friction Disk Surface always. The deficiency of friction plate shear resistance, light then braking effect lost efficacy, can cause time serious that blower fan frictional disk damages, and it is very high in the expense of wind field replacing frictional disk, up to units tens of or up to a million, and the problems such as the vibration of wind power generation yaw system, noise, mechanical system life-span and reliability are also produced certain impact by dust accumulation, not only affect properly functioning, the life and reliability of Wind turbines, and cause environmental pollution.
Summary of the invention
For solving the problems referred to above, this utility model provides a kind of Wind turbines driftage friction plate, the shear resistance of this driftage friction plate significantly improves, adapt to the brake request of high-power wind-driven generator group yaw system, avoid the major accident because friction plate shearing force deficiency causes, the dust of friction plate grinding simultaneously can pass through dust discharging grooves and discharge, and improves its mechanical life and performance.
The purpose of this utility model is achieved through the following technical solutions: a kind of Wind turbines driftage friction plate, it is characterized in that outputing according to steel backing size the shearing resistance dust discharging grooves of deep 3mm width 5mm on the bright finish steel backing bonding plane of original friction plate, the tangential direction that this groove and frictional disk circumferentially move chooses the angle of 30 ��ܦ���60 �� according to braking dish diameter.
This Wind turbines driftage friction plate ensure that the shear strength of brake block steel back and friction material, the steel backing intensity of brake block will not be therefore impacted, it have been experienced that improve the shear strength more than 40% of wind power yaw friction sheet, and driftage friction plate is operationally, dust is discharged along fluting direction smoothly by the rotation of frictional disk, thus reducing the vibration of yaw system, noise, rubbing surface is made to constantly update, and then improve yaw brake efficiency, it is ensured that the safety of unit, prolonged mechanical life-span.
Accompanying drawing explanationFig. 1 is original Wind turbines driftage friction plate steel back schematic diagram (front elevation).
Fig. 2 is this utility model Wind turbines driftage friction plate steel back schematic diagram (front elevation).
Fig. 3 is this utility model Wind turbines driftage friction plate steel back schematic diagram (side view).
Wherein: (1), friction plate steel back; (2) punching; (3) shearing resistance dust discharging grooves.
Detailed description of the inventionBelow in conjunction with drawings and Examples, the utility model is described in further detail.
In the present embodiment, take and carry out contrast test with a collection of friction plate finished product, Fig. 1 friction plate steel back (1) holes punched on surface (2), Fig. 2 steel backing (1) surface increase shearing resistance dust discharging grooves (3), by wind power yaw friction sheet by omnipotent experiment puller system carry out equal conditions under shearing test verify.
Test result indicate that: friction plate steel back friction plate shear strength��3.5Mpa with punching in Fig. 1; In Fig. 2 friction plate bonding plane surface fluting shear strength >=5Mpa, and enable to driftage friction plate grinding dust get rid of smoothly.
