Abstract
The utility model relates to a wind power generation equipment field, in particular to fan gear box high-speed shaft seal structure, its seal structure includes: the oil slinger has the advantages that the oil slinger enhances the oil slinging effect through the grate tooth structure on the oil slinger, the V-shaped sealing piece prevents lubricating oil from leaking, meanwhile, the added oil slinger blocks the circulation of lubricating oil, the diameter of the oil hole on the inner side of the end cover is reduced, the oil supply quantity is reduced, and the oil leakage can be effectively reduced.
Description
Technical Field
The utility model relates to the field of wind power generation equipment, in particular to a high-speed shaft sealing structure of a fan gear box.
Background
The traditional high-speed shaft sealing structure of the fan gear box adopts non-contact labyrinth sealing, a gap is designed between the oil resistance ring and the oil retainer, certain oil gas leakage can be avoided under normal conditions, and the problem of oil leakage of the high-speed shaft of the wind turbine generator cannot be thoroughly solved. After the lubricating oil leaks, the gearbox of the wind turbine generator is damaged, serious pollution is caused to the wind turbine generator and the environment, equipment parts are damaged when the lubricating oil is light, and fire disasters are caused when the lubricating oil is heavy. In the event of a fire, wind power plants may be exposed to damage to the equipment and to significant economic losses due to interruption of the power supply.
Disclosure of Invention
In order to solve the technical problems, the technical scheme provided by the utility model is a high-speed shaft sealing structure of a fan gear box, the sealing structure comprises: the oil slinger comprises a box body, an oil slinger, a V-shaped sealing piece, an outer end cover, an inner end cover and a transmission shaft. The sealing structure is provided with an oil slinger which is mounted on the transmission shaft and synchronously rotates with the transmission shaft; a V-shaped sealing piece is arranged between the oil slinger and the outer end cover; the oil slinger is sleeved on the periphery of the oil slinger and is mounted to the box body, and the oil slinger rotates relative to the oil slinger.
As an improvement, the oil slinger is provided with grate teeth which are of groove structures, so that the oil slinger is enhanced in oil slinger effect.
As an improvement, the oil retainer is arranged between the inner end cover and the outer end cover, and is designed into a labyrinth structure to separate oil return cavities at the inner side and the outer side and block the circulation of lubricating oil.
As improvement, the diameter of the oil hole at the inner side of the end cover is reduced, and the oil supply quantity is reduced.
Compared with the prior art, the utility model has the advantages that:
this structural design is reasonable, and its beneficial lies in that through the castor structure on the oil slinger has strengthened the oil slinger effect, and V type sealing member prevents the seepage of lubricating oil, and simultaneously, the circulation of lubricating oil is blocked to the oil slinger that increases, and the inboard oilhole diameter of end cover diminishes and has reduced the oil supply volume, can effectually reduce the oil leak.
