Abstract
The utility model discloses a yaw brake which comprises a symmetrically-connected yaw brake main body, wherein the yaw brake main body is internally and correspondingly provided with a piston, the piston is connected with an oil supply pipeline in the yaw brake main body, the oil supply pipeline is connected with a hydraulic station, a friction plate component is tightly fit in the yaw brake main body and on the piston, and the friction plate component is tightly matched with the yaw brake main body. The friction plate component is tightly adhered on the piston and is integrally connected with the piston, and a disassembly hole with a screw thread is arranged on a base plate of the friction plate, so that the friction plate component is fast to disassemble and change; the friction plate component is arranged in the yaw brake main body and is precisely matched with the yaw brake main body, so that that the friction plate can not laterally move when the yaw brake is used for braking, and the seal reliability of the piston is guaranteed; and two seals are formed between the piston and the yaw brake main body due to a sealing piece and a dust-proof ring, so that the hydraulic oil can not be leaked effectively.
Description
Technical field
The utility model relates to the hydraulic loaded break, particularly a kind of off-course brake that is used for wind power generating set.
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.
The model utility content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of friction plate easy to loading and unloading, friction plate does not have Side movement when off-course brake is braked, and can effectively guarantee the wind power generating set off-course brake of piston seal reliability.
The technical solution of the utility model is achieved in that a kind of off-course brake, comprise the off-course brake main body that symmetry connects, correspondence is provided with piston in described off-course brake main body, it is characterized in that: the oil feed line in described piston and the off-course brake main body is connected, described oil feed line is connected with hydraulic station, in described off-course brake main body, be closely fitted with friction plate assembly on the piston, described friction plate assembly and off-course brake main body closely cooperate.
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 in friction plate substrate top, and the bottom and the piston of described friction plate substrate fit tightly.
Off-course brake described in the utility model, its described friction plate substrate are provided with for the dismounting tapped hole.
Off-course brake described in the utility model, it is provided with Sealing between described piston and off-course brake main body.
Off-course brake described in the utility model, its described Sealing adopts U RunddichtringO and O RunddichtringO to combine.
Off-course brake described in the utility model, it also is provided with dust ring between described piston and off-course brake main body.
Friction plate assembly of the present utility model is close on the piston, be not connected as a single entity with piston body, and the friction plate substrate is provided with threaded removal hole, is convenient to friction plate assembly dismounting and change fast like this; And friction plate assembly places in the off-course brake main body and precision-fit with it, makes friction plate not have Side movement when off-course brake is braked, and has guaranteed the reliability of piston seal; The setting of Sealing and dust ring makes between piston and the off-course brake main body and forms two seals, and dust ring can also effectively prevent hydraulic oil pollution simultaneously, improves the working life of break, prolongs its turn(a)round.
Description of drawings
