Description
Technical field
The present invention relates to wind turbine gearboxes, and in particular to a kind of wind turbine gearbox output shaft oil-returning structure.
Background technique
Wind turbine gearbox is the critical component of wind power generating set, and the output shaft of gear-box is connected to by flexible clutch
The rotation speed of the rotor of generator, working condition lower tooth roller box output shaft is higher, and bearing heating amount is larger.Therefore, for defeated
The cooling and lubricating oil stream amount of axle bearing is usually maximum out.In actual operation, often occur setting due to lubricating oil return structure
It counts unreasonable, causes lubricating oil to have little time to return to oil sump and assemble here, finally, extra lubricating oil is between labyrinth seal
It is leaked out in gap, polluted gear-box external environment.The maintenance cost and wind turbine of bring gear-box due to leakage of oil
The economic loss that group stops power generation may be up to millions of members.
As shown in Figure 1, common a kind of wind turbine gearbox output shaft oil-returning structure in the market, including output shaft 1, end cap 2,

Oil return line 3-4 and the first oil return line 3-1, the second oil return line 2-2 being respectively provided on end cap 2 and third oil return line 2-3, Yi Jishe
It sets on end cap 2 and first oil pocket 2- corresponding with the first oil return line 3-1, the second oil return line 2-2 and third oil return line 2-3 respectively
4, the second oil pocket 2-5 and third oil pocket 2-6；Wherein, the left side of the right end of end cap 2 and cabinet 3 is tightly connected, the second labyrinth seal
8 and first labyrinth seal 7 or so be assemblied between output shaft 1 and end cap 2 side by side, with being sealed against and the second labyrinth seal 8 with
Third oil pocket 2-6 is corresponding, and the first labyrinth seal 7 is corresponding with the first oil pocket 2-4, the second oil pocket 2-5, and left bearing 4 and right bearing 5 are left
The right side is arranged side by side, be loaded between the output shaft 1 and cabinet 3 and left end of left bearing 4 with being sealed against and the right end of the first labyrinth seal 7 is close
The left end for sealing right end and the extension 3-5 of 3 right end of cabinet against, right bearing 5 is sealed against, and clearance adjustment ring 6 is loaded on cabinet 3
Between the outer ring of 5 left end of outer ring and right bearing of 4 right end of left bearing, oil input channel 11 is located at the outer ring and the right side of 4 right end of left bearing
Be connected at the outer ring of 5 left end of bearing and with the oilhole 6-1 in clearance adjustment ring 6, the first oil return line 3-1, the second oil return line 2-2 and
It is mutually communicated between third oil return line 2-3, plug 9 is removably installed on end cap 2 and corresponding with third oil pocket 2-6, work
Under state, the horizontal plane of input shaft 1 and cabinet 3 forms 5 ° of angle or so of operating angle a.The wind turbine gearbox of this structure exports
Axis oil-returning structure, since the shafting and horizontal plane of working condition lower tooth roller box are at one 5 ° or so of inclination angle a, the first oil return line
3-1, the second oil return line 2-2 and third oil return line 2-3 respectively with 2-6 pairs of the first oil pocket 2-4, the second oil pocket 2-5 and third oil pocket
Answer and between the first oil return line 3-1, the second oil return line 2-2 and third oil return line 2-3 be it is interconnected, then, work as gear-box
When work, lubricating oil passes throughOil input channel 11Enter inside gear-box from the oilhole 6-1 in clearance adjustment ring 6 to output shaft 1, end cap
2, when cabinet 3, the second labyrinth seal 8, the first labyrinth seal 7, left bearing 4, clearance adjustment ring 6 and right bearing 5 etc. are lubricated,
A part of lubricating oil returns to the oil sump (arrow in oil sump i.e. Fig. 1 downwards and to the right from the 4th oil return line 4 by the right end of right bearing 5
The pointed place of head, similarly hereinafter), a part of lubricating oil flows into the first oil pocket 2-4 by the left end of left bearing 4, in the parts of lubricating oil
Some lubricating oil oil sump can be entered by the first oil return line 3-1, other then can second time through being connected to the first oil return line 3-1
Oil circuit 2-2 flows backward into the second oil pocket 2-5.Similarly, the lubricating oil in the second oil pocket 2-5 again some can by with second time
The third oil return line 2-3 of oil circuit 2-2 connection flows backward into third oil pocket 2-6, so that the lubricating oil meeting gathered in third oil pocket 2-6
It gradually increases and more than the gear oil ability of the second labyrinth seal 8, causes 8 seal failure of the second labyrinth seal and lead to leakage and dirty
Contaminate environment.Thus, leakproofness and the feature of environmental protection are poor.
