Accompanying drawing explanation
Fig. 1 is the schematic diagram of the hollow axle sealing structure of traditional wind turbine gearbox;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings with the utility model is described in further detail.
See Fig. 2, the hollow axle sealing structure of wind turbine gearbox of the present utility model, including;Electric pipeline, the hollow axle sleeve pipe 3 comprising endoporus A being positioned in the casing oil sump B of casing 1, one end of described hollow axle sleeve pipe 3 uses O-ring seals 9 to be tightly connected with entering spindle 2, and the other end is connected with hollow axle main body 4 integral hermetic.As seen from Figure 2, this utility model also includes inner sleeve 12, described inner sleeve 12 is positioned in the endoporus A of hollow axle sleeve pipe 3, its left end stretches out in the left end of the endoporus A of hollow axle sleeve pipe 3 and O-ring seals 9 and is tightly connected with entering spindle 2, its right-hand member stretches out in the right-hand member of the endoporus A of hollow axle sleeve pipe 3 and penetrates the right-hand member of hollow axle main body 4 and hollow axle main body 4 from a left side and be tightly connected, and described electric pipeline is assemblied in inner sleeve 12.So, after O-ring seals 9 life-time service is damaged inefficacy, when lubricating oil in casing oil sump B leaks into from this place of being tightly connected in the endoporus A of hollow axle sleeve pipe 3, owing to electric pipeline is assemblied in inner sleeve 12, leak into the lubricating oil in the endoporus A of hollow axle sleeve pipe 3 and can not pollute and damage the electric pipeline in inner sleeve 12, also would not cause wind turbine gearbox cisco unity malfunction.Then, the maintenance cost of wind turbine gearbox is reduced, it is to avoid cause economic loss.
Seeing Fig. 2, described inner sleeve 12 is Split type structure, and each split part uses attaching nut 13 to be tightly connected, and the most described inner sleeve 12 can be used attaching nut 13 to be tightly connected by multiple split parts and form.Such as, from Figure 2 it can be seen that described inner sleeve 12 includes left and right two parts, the most two-part right left end uses attaching nut 13 to be tightly connected.So can more easily inner sleeve 12 be installed in hollow axle sleeve pipe 3, thus will not be limited by cabin space, as required left-right parts or the more part employing attaching nut 13 of inner sleeve 12 are tightly connected and form, and more easily inner sleeve 12 is connected and installed in hollow axle sleeve pipe 3 between wind turbine gearbox and motor again.
Seeing Fig. 2, the left end of described inner sleeve 12 stretches out in the left end of the endoporus A of hollow axle sleeve pipe 3 and O-ring seals 9 and uses supported joint 14 to be tightly connected with entering spindle 2.So can raise the inner sleeve 12 position in hollow axle sleeve pipe 3, when preventing wind turbine gearbox from working, inner sleeve 12 swings in hollow axle sleeve pipe 3 and collides with hollow axle sleeve pipe 3, produces abnormal sound, reducing service life.
See Fig. 2, the right-hand member of described inner sleeve 12 stretch out in the endoporus A of hollow axle sleeve pipe 3 right-hand member and from a left side penetrate hollow axle main body 4 use about the right-hand member of plug 15 arranged side by side and hollow axle joint 11 and hollow axle main body 4 be tightly connected.So, when in interlayer long-pending have lubricating oil to need periodic maintenance time, it is possible to back out plug 15, get rid of long-pending oil so that periodic maintenance is more convenient easily.Inner sleeve 12 uses hollow axle joint 11 to be connected with hollow axle main body 4 and ensure that inner sleeve 12 and hollow axle main body 4 synchronous axial system.
Seeing Fig. 2, described hollow axle main body 4 is provided with spill port D at inner sleeve 12 with plug 15 place of being tightly connected.So, after endoporus A inner product has lubricating oil, lubricating oil therein can be released when safeguarding by this spill port D, make lubricating oil pass back in casing oil sump B, it is to avoid inner sleeve 12 is polluted, damaged.
See Fig. 2, between described plug 15 and hollow axle main body 4, be provided with the gasket seal 16 being assemblied on inner sleeve 12.Gasket seal 16 can play preferable sealing function, prevents oil from oozing out from binding face.
Seeing Fig. 2, described hollow axle joint 11 uses bolt group 17 to be connected with hollow axle main body 4.This makes hollow axle joint 11 can rotate with leading axle with hollow axle main body 4.
