Description
Technical field
The present invention relates to the hydraulic loaded break, particularly a kind of off-course brake for the MW class wind turbine group.
Background technique
Traditional break, the base of its fixed friction sheet and break main body are connected as a single entity, when needs are followed renewal of facing renewal, its operation is trouble very, often need whole break is carried out dismounting, and friction plate easily generation lateral movement when off-course brake is braked, oil leakage phenomenon caused.
In order to overcome above-mentioned technical problem, the claimant has applied for " a kind of off-course brake ", and application number is 201020666189.5 Chinese invention patent, and making friction plate assembly and off-course brake main body is detachable structure.But find in actual use, although friction plate assembly and off-course brake main body are two detachable component, but because in use, friction plate assembly and off-course brake main body need to be closely cooperated, be about to that friction plate assembly is stuck in the off-course brake main body closely, piston one side, connect by link again, like this when changing friction plate assembly, just taken down at last link, also very bothered but friction plate assembly will be taken out the off-course brake main body, wasted time and energy.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of wind power generating set off-course brake that can change quickly and easily friction plate assembly.
Technological scheme of the present invention is achieved in that a kind of wind power generating set off-course brake, comprise the symmetrical off-course brake main body that connects, correspondence is provided with piston respectively in described off-course brake main body, oil feed line in described piston and the off-course brake main body is connected, described oil feed line is connected with hydraulic station, it is characterized in that: on described off-course brake main body, the piston corresponding part is connected with respectively block by removable fasteners, described block one end cooperates with the off-course brake main body, form respectively a mounting groove in the mutual close side of piston, be respectively arranged with friction plate assembly in described mounting groove, described friction plate assembly connects with corresponding piston and closely cooperates with described mounting groove.
Wind power generating set off-course brake of the present invention, its described friction plate assembly comprises friction plate substrate and friction plate, and described friction plate is bonded on the friction plate substrate, and described friction plate substrate and piston fit tightly.
Wind power generating set off-course brake of the present invention, it is provided with for the dismounting tapped hole at described friction plate substrate, and described friction plate is connected with the friction plate substrate by screw.
Wind power generating set off-course brake of the present invention, it is provided with wear detector in described off-course brake main body, and the contact of described wear detector is close on the friction plate.
Wind power generating set off-course brake of the present invention, it is provided with Sealing between described piston and off-course brake main body.
Wind power generating set off-course brake of the present invention, its described Sealing adopts U-shaped seal ring and y-type seal ring to combine.
The mounting groove of the present invention by friction plate assembly being placed block and off-course brake main body form when needs are changed friction plate assembly, only needs block is unclamped, and just can easily and fast the friction plate assembly in the mounting groove be taken out; And friction plate assembly places in the mounting groove and precision-fit with it, and when off-course brake was braked, friction plate assembly did not have Side movement, had guaranteed the reliability of piston seal; Simultaneously, the wear detector that is installed on the off-course brake body can carry out on-line monitoring and with the wear signal output that detects to the wear extent of friction plate.
Description of drawings
Fig. 1 is cross-sectional view of the present invention.
Mark among the figure: 1 is the off-course brake main body, and 2 is piston, and 3 is oil feed line,, 4 is block, and 5 is the friction plate substrate, and 6 is friction plate, and 7 is wear detector, 8 is Sealing.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make purpose of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of wind power generating set off-course brake comprises by the symmetrical off-course brake main body 1 that connects of screw rod, be provided with piston 2 in described off-course brake main body 1 interior correspondence, described piston adopts the special steel material, chrome-faced polishing, protection sealing in the time of antirust; Oil feed line 3 in described piston 2 and the off-course brake main body 1 is connected, described oil feed line 3 is connected with hydraulic station, between described piston 2 and off-course brake main body 1, be provided with Sealing 8, described Sealing 7 adopts U-shaped seal ring and y-type seal ring to combine, and has good low pressure seal performance.
On described off-course brake main body 1, piston 2 corresponding parts are connected with respectively block 4 by removable fasteners, described block 4 one ends cooperate with off-course brake main body 1, form respectively a mounting groove in piston 2 mutual close sides, be respectively arranged with friction plate assembly in described mounting groove, described friction plate assembly connects with corresponding piston 2 and closely cooperates with described mounting groove; Described friction plate assembly comprises friction plate substrate 5 and friction plate 6, described friction plate 6 is bonded on the friction plate substrate 5, described friction plate substrate 5 fits tightly with piston 2, described friction plate adopts organic material, have good wearability can, operating noise is low, is provided with threaded removal hole at described friction plate substrate 5, described friction plate 6 is connected with friction plate substrate 5 by screw, is convenient to friction plate replacing and connection.
Wherein, be provided with wear detector 7 in described off-course brake main body 1, the contact of described wear detector 7 is close on the friction plate 6, can carry out on-line monitoring and with the wear signal output that detects to the wear extent of friction plate.
This off-course brake adopts high-strength bolt according to being fixed on the frame in cabin through the enough moment of calculating.When wind power generating set need to be gone off course braking, oil pressure loads, the pressure oil pushing piston, friction plate is pressed on the brake disc, thereby produces clamping force, this break has six oil pockets, (16MPa) can produce approximately 500KN of clamping force during high oil pressure, wherein a plurality of pressure oil pipe interfaces can be conducive to different oil pipe connections, and the drain line inside of the drain line of each braking body and two braking bodies all communicates; After the hydraulic circuit pressure release, braking force is eliminated, and friction plate unclamps, and brake disc can rotate freely again.When yaw system drove the engine rooms of wind power generators rotation, off-course brake provided damping torque under low oil pressure, eliminated backkick backlash, realized that driftage turns to, and (3MPa) can produce approximately 100KN of clamping force during low oil pressure.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
