Description
Technical field
The present invention relates to wind turbine gearbox, be specifically related to a kind of large-scale wind electricity gear-box planet carrier.
Background technique
The first order adopts the planetary gear train transmission usually in the wind turbine gearbox, and this grade planet carrier will be subject to the low-speed heave-load effect usually, and is therefore very high to the requirement of strength of structure.Existing large-scale wind electricity gear-box is made of adpting flange and carrier main-body with planet carrier, is generally the overall structure of integrally casting moulding.Because its global shape, complex structure, enormous size, thereby design, make, process all very difficult.Especially the planet carrier of 3MW and above large-scale wind electricity gear-box because the safety coefficient requirement is very high, must use cast steel could satisfy performance requirement; Thereby so that the casting technique difficulty of integral cast steel planet carrier is very large, yield rate is not high.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple in structure, easy processing, safe and reliable large-scale wind electricity gear-box planet carrier.
For solving the problems of the technologies described above, the present invention takes following technological scheme;
The split type planet carrier of large-scale wind electricity gear-box of the present invention comprises adpting flange and carrier main-body, it is characterized in that; Described adpting flange and carrier main-body are Split type structure, described adpting flange one end is the outwardly land of radius vector, described carrier main-body one end is to the outwardly connected unit of axle, and described adpting flange is fixedly connected with connected unit by land with carrier main-body;
Described land is provided with attachment hole, and described connected unit is provided with mounting hole, and described adpting flange and carrier main-body are with bolts by the attachment hole on the land and the mounting hole on the connected unit;
Described land is provided with attachment hole, and described connected unit is provided with mounting hole, and described adpting flange is connected the mounting hole employing link connection that the attachment hole on the land is connected with connected unit with carrier main-body;
Described link is comprised of bolt and locating stud, and described locating stud is hollow pin, is set on the described bolt, and the bolt two ends are connected with the mounting hole that the attachment hole on the land is connected with connected unit;
Described land is provided with attachment hole, and described connected unit is provided with mounting hole, and described adpting flange is connected the mounting hole that the attachment hole on the land is connected with connected unit and adopts bolt to be connected with link with carrier main-body; The quantity of described bolt and link is identical or not identical;
Described adpting flange material is cast iron;
Described carrier main-body material is cast steel.
The present invention has following beneficial effect with respect to prior art;
1, because large-scale wind electricity gear-box integral body of the present invention is Split type structure, adpting flange and carrier main-body are independent structure, thereby relatively adpting flange and carrier main-body be the structure of the large-scale wind electricity gear-box of integral body, relatively simple for structure, adpting flange and carrier main-body can be cast separately, therefore significantly reduce the parts of Casting technology difficulty, improve product percent of pass, reduce manufacture cost.
2, adpting flange is connected bolt or link and connects the moment of torsion can indirectly guarantee planet carrier integral body and transmit safe and reliable with carrier main-body.
3, adpting flange adopts cast iron materials, satisfies under the condition of safety coefficient requirement, saves cost.
4, carrier main-body adopts cast steel material, compares cast iron and has better reliability and Security.
