A kind of wind driven generation set main shaft by gears meshing and gear-box linkage structure, be on main shaft and gearbox input shaft, process straight-tooth internal tooth and cydariform external tooth respectively, main shaft and gear-box are engaged completely by described straight-tooth internal tooth and described cydariform external tooth and realize moment of torsion transmission.Described straight-tooth internal tooth and cydariform external tooth interchanging positions, and can replace directly carrying out Gear Processing by installing respective gears.By adopting this flexible connection mode, main-shaft axis and gearbox input shaft axis allow a small amount of radial and axial skew and certain augular offset, main shaft, gear-box, the stressed equal relative simplicity of main bearing between main shaft and mainframe, the corresponding minimizing of dynamic additional load between several parts, reduce the Design and manufacture requirement of main shaft, machine's drive chain structure is compacter, improves the designed reliability of blower fan.Gear-box and main bearing rate of fault can be reduced simultaneously, extend its working life.And this structure is for convenience detach, effectively maintenance efficiency can be improved.
Description
Technical field
The utility model relates to a kind of wind driven generation set main shaft by gears meshing and gear-box linkage structure.
Background technique
At present, the connection of domestic and international horizontal axis wind-driven generator group main shaft and gear-box adopts rigid construction, and common form comprises and connects main shaft and gearbox input shaft by locking plate or be directly connected main shaft and gearbox input shaft and other structure by bolt.
Connect main shaft and gearbox input shaft structure by locking plate, need longer main shaft, whole cabin lengthens; Main axe intensity require and manufacture requirements high; The stressed complexity of main bearing, the impact of gear-box acceptor bearing structure need bear larger additional load, and stressing conditions is complicated.
Directly connect main shaft and gearbox input shaft by bolt, main bearing is greatly stressed, and gear-box need bear the additional load because deadweight and stand stretch cause, and stressing conditions is complicated.
Larger load-bearing and the stressing conditions of complexity easily cause gearbox fault, the corresponding increase of dynamic additional load of simultaneously bearing to the generator that gear-box connects, improve the rate of fault of wind-driven generator group wheel box and generator, cause high maintenance and repair cost, and reduce equipment service life.
Summary of the invention
In order to improve the deficiency of existing Placement, the utility model provides a kind of wind driven generation set main shaft by gears meshing and gear-box linkage structure, this structure adopts straight-tooth internal tooth and cydariform external tooth to engage this flexible connecting structure, effectively can reduce the additional load that main shaft is delivered to gear-box, reduce the stressed complexity of gear-box.
The utility model is by the following technical solutions: on main shaft, process straight-tooth internal tooth, gearbox input shaft processes cydariform external tooth, main shaft realizes moment of torsion transmission with gear-box by described straight-tooth internal tooth and engaging completely of cydariform external tooth.
Wherein, described straight-tooth internal tooth and cydariform external tooth interchanging positions, namely process cydariform external tooth, gearbox input shaft process straight-tooth internal tooth on main shaft.
Described straight-tooth internal tooth can replace directly on main shaft or gearbox input shaft, processing straight-tooth internal tooth by installing straight-tooth internal-gear on main shaft or gearbox input shaft.
Described cydariform external tooth can replace directly on main shaft or gearbox input shaft, processing cydariform external tooth by installing cydariform external tooth gear on main shaft or gearbox input shaft.
Adopt a kind of wind driven generation set main shaft by gears meshing described in the utility model and gear-box linkage structure, engaged completely by straight-tooth internal tooth and cydariform external tooth and realize flexibly connecting of main shaft and gear-box, main-shaft axis and gearbox input shaft axis allow a small amount of radial and axial skew and certain augular offset, the moment of flexure that main shaft is subject to and be subject to mainframe distortion impact can not pass to gear-box, additional load to gear-box transmission obviously reduces, main shaft, gear-box, the stressed equal relative simplicity of main bearing between main shaft and mainframe, the corresponding minimizing of dynamic additional load between gear-box and generator.Reduce the Design and manufacture requirement of blower fan to main shaft, machine's drive chain structure can be compacter, and the design of blower fan is more reliable.Gear-box and main bearing rate of fault can be reduced simultaneously, extend its working life.Jointly realize the reduction of blower fan cost, improve blower fan stability and reliability.Even if when gear-box breaks down, the more convenient dismounting of linkage structure of this flexibility, effectively can improve maintenance efficiency.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of wind driven generation set main shaft by gears meshing and gear-box linkage structure is shown in figure, this structure processes straight-tooth internal tooth 3 on main shaft 1, gearbox input shaft 4 processes cydariform external tooth 2, and main shaft 1 realizes moment of torsion transmission with gear-box 5 by described straight-tooth internal tooth 3 and engaging completely of cydariform external tooth 2.
Wherein, described straight-tooth internal tooth 3 and cydariform external tooth 2 interchanging positions, namely process cydariform external tooth 2, gearbox input shaft 4 process straight-tooth internal tooth 3 on main shaft 1.
Described straight-tooth internal tooth 3 can replace directly on main shaft 1, processing straight-tooth internal tooth 3 by installing straight-tooth internal-gear on main shaft 1.
Described cydariform external tooth 2 can replace directly on gearbox input shaft 4, processing cydariform external tooth 2 by installing cydariform external tooth gear on gearbox input shaft 4.
This flexible connecting structure is engaged by straight-tooth internal tooth 3 and cydariform external tooth 2 by adopting, main shaft 1 axis and gearbox input shaft 4 axis allow a small amount of radial and axial skew and certain augular offset, the moment of flexure that main shaft 1 is subject to and be subject to mainframe distortion impact can not pass to gear-box 5, the additional load transmitted to gear-box 5 obviously reduces, main shaft 1, gear-box 5, the stressed equal relative simplicity of main bearing between main shaft 1 and mainframe, the corresponding minimizing of dynamic additional load between gear-box 5 and generator.Reduce the Design and manufacture requirement of blower fan to main shaft 1, machine's drive chain structure can be compacter, and the design of blower fan is more reliable.Gear-box 5 and main bearing rate of fault can be reduced simultaneously, extend its working life.Jointly realize the reduction of blower fan cost, improve blower fan stability and reliability.Even if when gear-box 5 breaks down, the more convenient dismounting of this linkage structure, effectively can improve maintenance efficiency.
