The periphery of leading axle upwind end cap 2 between end cap 2 is equipped with the O-ring seal 11 of two spacing arrangements, its existing skill
Art problem is；Two O-ring seals 11 are located on the periphery of leading axle upwind end cap 2, and guide shaft body 1 more up to 1m.
Therefore, assemble relatively difficult and easily 11 scratch of O-ring seal, sealing effect are difficult to be guaranteed, pacified in assembling process
Full property and reliability are poor.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of higher wind turbine gearbox leading axle of safety and reliability
Sealing structure.
In order to solve the above technical problems, the present invention adopts the following technical scheme that；
A kind of wind turbine gearbox guides axle sealing structure, including O-ring seal, is supported in the interior of second level input shaft end cap
Bearing in hole, the guiding shaft body that left end is connected with leading axle upwind end cap, right end is connected with guiding pipe spreader are described to draw
Guide shaft upwind end cap is assemblied on planet carrier, is assemblied on the right side of the guiding pipe spreader under leading axle on wind direction end cap, institute
State the left end of wind direction end cap under leading axle to be connected with the right end of second level input shaft end cap, the second level input shaft end cap assembling
In on back box lid, the bearings in the endoporus of second level input shaft end cap, it is characterized in that：The O-ring seal sealing
Ground is assemblied between the periphery of leading axle upwind end cap and the endoporus of planet carrier.
Preferably, it is equipped with ring-type O-ring seal between the endoporus of the guiding shaft body and the periphery of guiding pipe spreader.
Preferably, bearings sleeve is further included, the bearings sleeve radially loading is assigned in guiding shaft body and bearing
Between and right end and guide pipe spreader left end it is detachably connected.
Preferably, under the guiding pipe spreader and leading axle contactless labyrinth sealing is equipped between wind direction end cap.
Preferably, it is equipped with the leading axle between the left side of wind direction end cap and the right side of second level input shaft end cap
Annular end face O-ring seal.
Preferably, it is equipped with drainback passage between the contactless labyrinth sealing and guiding pipe spreader.
Preferably, skeleton sealing is further included, the skeleton sealing is assemblied in periphery and the leading axle of guiding pipe spreader
Between the endoporus of lower wind direction end cap right end.
Compared with prior art, the present invention includes following beneficial effect；
Since the O-ring seal is hermetically assemblied between periphery and the planet carrier endoporus of leading axle upwind end cap.
Therefore, as long as O-ring seal is first assemblied on the periphery of leading axle upwind end cap, then at the same time by leading axle upwind end cap
On the endoporus for being installed on planet carrier and the periphery for guiding shaft body, O-ring seal is just hermetically assemblied in leading axle upwind
Between the periphery of end cap and the endoporus of planet carrier.Then, O-ring seal scratch, sealing effect will not be obtained in assembling process
To guarantee, so that safety and reliability is higher.
Brief description of the drawings
Fig. 1 is the schematic diagram of traditional wind turbine gearbox guiding axle sealing structure；
Fig. 2 is the structure diagram of the present invention.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Shown in Figure 2, wind turbine gearbox guiding axle sealing structure of the invention, including O-ring seal 11, is supported in the
Bearing 12 in the endoporus of two level input shaft end cap 6, left end is connected with leading axle upwind end cap 2, right end is with guiding pipe spreader 4
The guiding shaft body 1 of connection, the leading axle upwind end cap 2 are assemblied on planet carrier 3, the right side of the guiding pipe spreader 4
It is assemblied under leading axle on wind direction end cap 5, the right side of the left end of wind direction end cap 5 and second level input shaft end cap 6 under the leading axle
End connection, the second level input shaft end cap 6 are assemblied on back box lid 7, and the bearing 12 is supported in second level input shaft end cap 6
Endoporus in.From Figure 2 it can be seen that the O-ring seal 11 is hermetically assemblied in periphery and the planet carrier of leading axle upwind end cap 2
Between 3 endoporus.Therefore, as long as O-ring seal 11 is first assemblied on the periphery of leading axle upwind end cap 2, then at the same time will
Leading axle upwind end cap 2 is installed on 3 endoporus of planet carrier and the periphery for guiding shaft body 1, just by O-ring seal 11 hermetically
It is assemblied between 3 endoporus of periphery and planet carrier of leading axle upwind end cap 2.Then, will not be by O-shaped sealing in assembling process
11 scratches are enclosed, its sealing effect is guaranteed, so that safety and reliability is higher.
From Figure 2 it can be seen that it is O-shaped close to be equipped with ring-type between the endoporus of the guiding shaft body 1 and the periphery of guiding pipe spreader 4
Seal 14.This make it that the sealing effect of the present invention is more preferable, and safety and reliability is also more preferable.
From Figure 2 it can be seen that present invention additionally comprises bearings sleeve 8,8 radially loading of bearings sleeve is assigned in leading axle
Between main body 1 and bearing 12 and right end is with guiding the left end of pipe spreader 4 detachably connected.So, ring-type O-ring seal
When being needed replacing after 14 failures, wind direction end cap 5 under leading axle, guiding pipe spreader 4 and bearings can be more easily pulled down
Sleeve 8, carries out repair and replacement to the ring-type O-ring seal 14 after failure, makes the repair and replacement side of ring-type O-ring seal 14
Just it is easy.
From Figure 2 it can be seen that contactless labyrinth type is equipped between wind direction end cap 5 under the guiding pipe spreader 4 and leading axle
Sealing 13.This causes the sealing effect of the present invention to be further guaranteed, so that safety and reliability is also further carried
It is high.
From Figure 2 it can be seen that under the leading axle left side of wind direction end cap 5 and second level input shaft end cap 6 right side it
Between be equipped with annular end face O-ring seal 15.This make it that the sealing effect of the present invention is more preferable, so that safety and reliability is also more
It is good.
From Figure 2 it can be seen that it is equipped with drainback passage 16 between the contactless labyrinth sealing 13 and guiding pipe spreader 4.
Lubricating oil can so flowed out by drainback passage 16 between contactless labyrinth sealing 13 and guiding pipe spreader 4, is kept away
Exempt from this accumulate it is more and more, influence sealing effect.
From Figure 2 it can be seen that further include it is skeleton sealing 9, it is described it is skeleton sealing 9 be assemblied in guiding pipe spreader 4 peripheries with
Under leading axle between the endoporus of 5 right end of wind direction end cap.It can so prevent lubricating oil will not be from the periphery of guiding pipe spreader 4 with drawing
Outwards leaked out between the endoporus of 5 right end of wind direction end cap under guide shaft, make the sealing effect of the present invention more preferable.
