Problems solved by technology
[0004] Due to the limited pressure of the O-ring 1' and the bonding surface of this end face seal structure, the ability to withstand oil pressure is limited, and because the material of the O-ring 1' has a lifespan, if the material of the O-ring 1' ages, the elasticity will deteriorate , the pressure oil may leak from the joint surface of the box body 2' and the ring gear 3', resulting in oil leakage from the wind power gearbox
In addition, since the box body 2' and the ring gear 3' are key structural parts, if they cannot be replaced on the tower, the wind power gearbox must be taken off the shelf for maintenance, which increases the maintenance cost in the later period

The invention relates to the technical field of sealing, and discloses a novel oil way sealing structure. The novel oil way sealing structure is used for sealing an oil way at the junction surface ofa first structural member and a second structural member, and comprises a first counter bore, a second counter bore, and a sealing connector, wherein the first counter bore is formed in the junction surface of the first structural member and communicates with a first oil hole in the first structural member, the second counter bore is formed in the junction surface of the second structural member,the second counter bore communicates with a second oil hole in the second structural member, and one end of the sealing connector is inserted into the first counter bore in a sealed mode, the other end of the sealing connector is inserted into the second counter bore in a sealed mode, a communicating hole is formed in the sealing connector, and the first counter bore and the second counter bore communicate through the communicating hole. By means of the structure, the novel oil way sealing structure is good in sealing effect, free of service life limitation and failure risks and capable of avoiding maintenance.
Description
technical field [0001] The invention relates to the technical field of sealing, in particular to a novel oil passage sealing structure. Background technique [0002] In wind turbines, since the speed of the wind rotor is very low, it is far below the speed required by the generator for power generation. It is necessary to increase the speed of the wind power gearbox to make the generator obtain the corresponding speed. The wind power gearbox is an important Core components play a vital role in wind power equipment. [0003] The wind turbine gearbox is located inside the nacelle of the wind turbine. Its working environment is special and maintenance is inconvenient. Therefore, the wind turbine gearbox generally adopts an internal oil circuit design to avoid pipeline maintenance problems caused by external pipeline oil leakage. At present, in the oil circuit of the wind power gearbox, the joint between the first structural part and the second structural part generally adopts ...
