Specific implementation mode
In the following, elaborating to the preferred embodiment of the present invention in conjunction with attached drawing.
Referring to Fig. 2 to Fig. 5, wind turbine gearbox of the invention guides axle sealing structure, including gear box casing 11, right end
The planet carrier left bearing 12 and planet carrier right bearing 13 arranged by spacing are assemblied in the planet in the left end of gear box casing 11
Frame 9, left end are assemblied in planet carrier 9 and longer guiding shaft body by using the guiding hubcap 6 of bolt 8 and planet carrier 9
1, left end is connect with the right end of guiding shaft body 1, passes on left guiding axle bearing 14 and right end cap 15 is assemblied in gearhousing
Guiding pipe spreader 2 in the right end of body 11 is assemblied in respectively in the left end of guiding shaft body 1 and the right end of guiding pipe spreader 2
Two cable fixing sleeves 5 are partly located among axially directed shaft body 1 and guiding pipe spreader 2 and both ends are respectively by two electricity
Cable fixing sleeve 5 stretches out in the cable 4 except the left end of axially directed shaft body 1 and the right end of guiding pipe spreader 2, is set in row
In carrier 9 and with the left end of gear box casing 11 it is radial and axial against left end cap 10 and axial be assemblied in guiding hubcap 6
O-ring seal I 7 between planet carrier 9 and two O-ring seals II 3.By Fig. 2 to Fig. 5 as it can be seen that the guiding shaft body
It is equipped with the gap axis sealing surface 1-1 and sealing face 1-2 that outer diameter changes from small to big on 1 periphery successively by right end to left side, it is corresponding
Ground, the guiding pipe spreader 2 by left end to right side be equipped with aperture sealing hole 2-2 from large to small and clearance seal hole 2-1 and
It is set on the clearance seal hole 2-1 there are two the annular seal groove 2-4 of spacing arrangement, described two O-ring seals II 3 are assemblied in
In described two annular seal groove 2-4 and it is set on the gap axis sealing surface 1-1 of guiding shaft body 1, the guiding pipe spreader 2
Left end pass through sealing hole 2-2, clearance seal hole 2-1, sealing face 1-2, gap axis sealing surface 1-1 and guiding shaft body 1
Right end be removably tightly connected and sealing hole 2-2 and sealing face 1-2 be interference fit connect, the guiding shaft body 1 and
Hubcap 6 is guided 16 to be welded to connect at the left end that they are located in gear box casing 11.Then, through long-term running two O
Type sealing ring II 3 fails, and lubricating oil penetrates into guiding shaft body 1 and guides the inside of pipe spreader 2 and carried out to cable 4 therein
It impregnates, leads to 4 cisco unity malfunction of cable, and then cause wind turbine gearbox cisco unity malfunction, it is necessary to O-shaped to two of failure
When sealing ring II 3 is changed or is repaired.Obviously, as long as by the guiding axle sleeve detachably connected with guiding shaft body 1
Pipe 2 is dismantled, so that it may will be assemblied in described two annular seal groove 2-4 and be set in the gap axis sealing surface of guiding shaft body 1
Two O-ring seals II 3 on 1-1 remove replacement or repair.And guiding pipe spreader 2 is dismantled, only relate to dismounting leading axle
Bearing 14 and right end cap 15.It is once oozed inside the leading axle of axle sealing structure in particular, being guided there is no traditional wind turbine gearbox
Oil can not independent disassembling repair, the problem of getting only integral replacing wind turbine gearbox.As it can be seen that the present invention repair be easy and cost compared with
It is low.
Referring to Fig. 2 to Fig. 5, in the present invention, the right end of the sealing face 1-2 in the guiding shaft body 1 is equipped at least
Two circumferentially spacing arrangement interconnecting piece 1-3, accordingly, it is described guiding pipe spreader 2 on sealing hole 2-2 left end be equipped with
The mating connection portion 2-3 of interconnecting piece 1-3 connections.This to guide shaft body 1 and guide the assembly of pipe spreader 2 more secured and tear open
Unload still more convenient be easy.
Referring to Fig. 2 to Fig. 5, in the present invention, it is described guiding shaft body 1 on sealing face 1-2 right end be equipped with to
The few two interconnecting piece 1-3 that circumferentially spacing is arranged are the protrusion to extend radially outwardly, accordingly, on the guiding pipe spreader 2
Sealing hole 2-2 the notches that extend radially outwardly of the mating connection portion 2-3 being connect with interconnecting piece 1-3 that is equipped with of left end.This makes
Interconnecting piece 1-3 connections mating connection portion 2-3 it is relatively simple for structure, manufacture be easier.
Referring to Fig. 4 and Fig. 5, in the present invention, the radial cross-sectional shape of the interconnecting piece 1-3 is rectangle, accordingly, described
The radial cross-sectional shape of mating connection portion 2-3 is rectangle.This makes the mating connection portion 2-3 structures of interconnecting piece 1-3 connections more
Simply, manufacture is more prone to.Certainly, the radial cross-sectional shape of the socket part 1-3 may be trapezoidal either semicircle or three
Angular or sawtooth projection, accordingly, the radial cross-sectional shape of the mating connection portion 2-3 are that rectangle is either trapezoidal or half
Round either triangle or indentation.This keeps the same mating connection portion 2-3 structures for obtaining interconnecting piece 1-3 connections simpler
Single, manufacture is more prone to.
In fact, in the present invention, guide the right end of the sealing face 1-2 in shaft body 1 to be equipped at least two
Circumferentially the interconnecting piece 1-3 of spacing arrangement can also be the notch extended radially inwardly, accordingly, on the guiding pipe spreader 2
Sealing hole 2-2 the protrusions that extend radially inwardly of the mating connection portion 2-3 being connect with interconnecting piece 1-3 that is equipped with of left end.This is same
Sample make the mating connection portion 2-3 of interconnecting piece 1-3 connections it is relatively simple for structure, manufacture be easier.
In fact, in the present invention, the radial cross-sectional shape of the interconnecting piece 1-3 may be rectangle, accordingly, described
The radial cross-sectional shape of mating connection portion 2-3 is rectangular preiection.This again such that interconnecting piece 1-3 connections mating connection portion 2-3
Structure is simpler, manufacture is more prone to.
In fact, in the present invention, the radial cross-sectional shape of the interconnecting piece 1-3 can with trapezoidal either semicircle or
Triangle or indentation, accordingly, the radial cross-sectional shape of the mating connection portion 2-3 be it is trapezoidal or semicircle or
Person's triangle or sawtooth projection.This is again such that the mating connection portion 2-3 structures of interconnecting piece 1-3 connections are simpler, make
It makes and is more prone to.
The operation principle of the present invention is to guide the sealing face 1-1 in shaft body 1 and the transition on guiding pipe spreader 2 close
Interference fit connection between cover hole 2-1, future bootstrap shaft body 1 and leading axle jacket exterior 2 a large amount of oil isolation
It opens.The O-ring seal II 3 of 2-4 in seal groove will be oozed between axis transition seal face 1-1 and hole transition seal face 2-1
The a small amount of oil leaked out is kept apart, and prevents it from entering inside leading axle, and guides shaft body 1 with guiding hubcap 6 in their positions
16 are welded to connect at the left end in gear box casing 11, then can ensure to be not in oil seepage phenomena herein.
The preferred embodiment of the present invention is elaborated above in conjunction with attached drawing, but the present invention is not limited to above-mentioned
Embodiment, skilled artisan within the scope of knowledge, present inventive concept can also not departed from
Under the premise of various changes can be made.
