Abstract
The utility model discloses a driving device of a wind turbine using a built-in main shaft type gear box, comprising a gear case body, a main shaft and a gear driving system. The device is characterized in that: the main shaft is position at the inner part of the gear case body by a main bearing, wherein, a flange at only one end of the main shaft extends outside of the gear case; the flange is directly connected with the impeller of a hub; and the main shaft is positioned at one end in the gear case body and is connected with a first class planet pinion shaft of the gear driving system. The gear case arranges the main shaft in the gear case body; and the flange which only extends outside of the case body is directly connected with the impeller, therefore, the device has the advantages of compact structure, smaller mechanical area of the engine room, shorter length of the main stander on the axis direction, light weight, low cost and good lubrication effect for forced lubrication and centralized lubrication.
Description
Technical field
The utility model relates to wind power generating set, more particularly, relates to the transmission device of the built-in king post system gear-box of tool in a kind of wind power generating set.
Background technique
Existing wind power generating set all is to utilize main shaft that wheel hub is supported, and various loads such as the end thrust that wheel hub is passed over, when pneumatic moment of flexure passes to frame moment of torsion is passed to gear-box.And existing main shaft all is located at outside the gear-box, and the Placement between itself and wheel hub, the gear-box has two kinds:
A kind of is two point-supported schemes, and promptly respectively there is a main bearing at the two ends of main shaft, support impeller and gear-box respectively.Wherein main shaft is connected with the shrink disk of gear-box by spherical bearing and thrust bearing for forging main shaft, be connected with the impeller of wheel hub by spline, thus transmitted load, impeller driftage and heeling moment are delivered on the mainframe by main shaft and bearing.
Another kind is the scheme of supported at three point, and promptly Bearing Installation as a strong point, is rigid support in a side of wheel hub impeller, and two strong points are arranged on the gear-box in addition, are elastic support, can absorb the sudden change load from blade.
The transmission scheme of above-mentioned two kinds of external main shafts has the following disadvantages:
1, the drive train size is big, and main shaft is external, and axis is long, directly influences the length and the weight of mainframe simultaneously;
2, transmission part weight increases, and cost increases, and the centering problem of impeller and main shaft and gear-box and main shaft highlights;
3, because main shaft places the gear-box outside, need the configuration lubrication system, increased the lubricated link of complete machine, thereby increased the link of safeguarding of complete machine, and the workload of safeguarding is big;
The model utility content
The purpose of this utility model is to provide the wind power generating set transmission device of a kind of compact structure, the built-in king post system gear-box of employing in light weight, that cost is low, reliability is high.
Adopt the wind power generating set transmission device of built-in king post system gear-box to include gear case body, main shaft and pinion unit in the utility model, described main shaft is positioned at the inside of described gear case body by main bearing, wherein only the flange of an end extends outside the described gear case body, described flange directly is connected with the impeller of wheel hub, and the end that described main shaft is positioned at described gear case body inside is connected with the first order planet axis of described pinion unit.
Be connected by spline between described main shaft and the described first order planet axis.
Described flange is close to described gear case body outer wall.
Adopting the wind power generating set transmission device of built-in king post system gear-box in the utility model is that main shaft is placed gear case body inside, only there is the flange that extends outside the casing directly to be connected with impeller, has compact structure, reduce the advantage of the mainframe length on Arrangement of Engine-room space and the axial direction, have in light weight simultaneously, save corresponding expense and adopt pressure centralized lubrication, advantages such as high lubricating effect.
Description of drawings
Fig. 1 is the cross-sectional schematic of wind power generating set transmission device in the utility model;
Fig. 2 is the structural representation that utilizes the wind power generating set behind the transmission device in the utility model.
Embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, adopt the wind power generating set transmission device of built-in king post system gear-box to include casing 1, main shaft 2, main bearing 3 and transfer gear train in the utility model, wherein:
Main shaft 2 is for forging main shaft, be located at gear case body 1 inside by main bearing 3, the flange 5 of the end outside of extending gear case body 1 wherein, directly directly be connected with impeller 4, the end that main shaft 2 is positioned at gear case body 1 inside is connected with the first order planet axis 7 of pinion unit by spline, and then be connected with the second level, third level planet axis 8,9, because gear transmission is a prior art, explanation no longer separately.
Main bearing 3 is respectively two-sided ball bearing and thrust bearing, adopts the pressure centralized lubrication in the lump with bearing, the gear of gear-box inside, thereby can reduce the setting of lubrication system.The load of wheel hub is delivered on the gear case body 1 by main bearing 3, finally is delivered on the mainframe 6.
In sum, adopt the transmission gear of wind generating set of built-in main shaft type gear box after use, to have following advantage in the utility model:
1, compact conformation reduces the mainframe length on Arrangement of Engine-room space and the axis direction;
2, in light weight, save corresponding expense;
3, in the built-in gear-box of base bearing, adopt and force centralized lubrication, high lubricating effect;
4, on-the-spot installation and maintenance workload is little;
5, impeller and built-in spindle mounted and on-the-spot centering are convenient.
