Description

Yaw brake oil discharging structure Technical Field The utility model relates to the technical field of wind power generation accessories, in particular to an oil discharging structure of a yaw brake. Background The yaw brake is an important component in the wind generating set, and is a braking device for controlling a yaw system of a nacelle of the wind generating set, and the yaw brake mainly aims to enable the nacelle to accurately stop at a preset position in the yaw process, keep the nacelle stable in the running process and prevent the nacelle from unnecessarily rotating due to factors such as wind direction change and the like. In the prior art, when the device is used, under the driving of hydraulic pressure, the piston acts, the ejection friction plate clamps the yaw brake disc, the rotation of the damping brake disc is achieved (the hydraulic pressure of the hydraulic driving piston is 5-25 bar unequal at the moment) or the yaw brake disc is prevented (the hydraulic pressure of the hydraulic driving piston is 160bar at the moment), the rotation of the damping driving piston is stopped for a long time from 5-25 bar to 160bar, the rotation is alternately operated, oil exuded from the sealing ring can be increased, the trapped pressure between the sealing ring and the dust ring is increased, the oil can leak out from the lip of the dust ring when not being discharged in time, the friction plate is polluted, and the friction plate needs to be replaced in the long-term use process of the device, so that the replacement is inconvenient. Disclosure of utility model The utility model aims to provide an oil discharging structure of a yaw brake, which solves the problems in the prior art. In order to achieve the above purpose, the yaw brake oil discharging structure comprises two cylinders, grooves are formed in two sides of the surface of each cylinder, a piston body is mounted on the inner wall of each groove, an oil discharging port is formed in each cylinder, an oil discharging groove is formed in each cylinder, a mounting plate is mounted at one end of each piston body, and a friction plate body is mounted at the other end of each mounting plate. As a preferred embodiment, one end of the oil drain port is communicated with the groove, and the other end of the oil drain port is communicated with the oil drain groove. As a preferable implementation mode, the top fixing sleeve on the surface of the piston body is provided with a dust-proof ring body, and the surface of the piston body is fixedly sleeved with a sealing ring body at equal distance.
