Abstract
The utility model discloses a yaw brake for a wind generating set. The yaw brake for the wind generating set comprises a yaw brake main body which is symmetrically connected, and pistons are correspondingly arranged inside the yaw brake main body and are connected with an oil supply pipeline inside the yaw brake main body. The oil supply pipeline is connected with a hydraulic station, and blocks are respectively connected with the yaw brake main body and the corresponding position of the piston through a detachable screw. One end of each of the blocks is matched with the yaw brake main body, and installation grooves are respectively formed at one side where the pistons are close to each other. Friction plate assemblies are respectively arranged inside the installation grooves and are connected with corresponding pistons and are closely matched with the installation grooves. According to the yaw brake for the wind generating set, the friction plate assemblies are arranged in the installation grooves which are formed by the blocks and the yaw brake main body. When the friction plates are needed to be replaced, the friction plate assemblies can be rapidly taken out from the installation grooves with the blocks being loosed so that the detachment and the replacement of the friction plate assemblies are convenient.

The technical solution of the utility model 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 described in the utility model, 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 described in the utility model, 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 described in the utility model, 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 described in the utility model, it is provided with Sealing between described piston and off-course brake main body.
Wind power generating set off-course brake described in the utility model, its described Sealing adopts U-shaped seal ring and y-type seal ring to combine.
The mounting groove of the utility model 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 utility model.
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 utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
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.
