Embodiment Construction

[0056] The present invention will be more clearly and completely described below by way of a preferred embodiment with reference to the accompanying drawings, but the present invention is not limited to the scope of the described embodiment.

[0057] Such as Figure 1-5 As shown, this embodiment provides a fixed shaft of a generator and a wind power generator including the same. The fixed shaft 1 includes a shaft body 11 and an intermediate flange 12 arranged on the outer wall of the shaft body 11. The intermediate flange 12 is used for Attach stator support 2. One end of the middle flange 12 away from the shaft body 11 is provided with a fixing part 13, at least one end of the fixing part 13 protrudes from the surface of the middle flange 12 along the axial direction of the fixed shaft 1 and extends towards the end of the shaft body 11, the stator The support 2 abuts against and connects to the fixing portion 13 .

[0058] By providing a fixing part 13 at the end of the mid...

Abstract

The invention discloses a fixing shaft of a generator and a wind driven generator comprising the same. The fixing shaft comprises a shaft body and a middle flange arranged on the outer side wall of the shaft body, the middle flange is used for being connected with a stator support, and a fixing part is arranged at the end, away from the shaft body, of the middle flange. At least one end of the fixing part protrudes out of the surface of the middle flange in the axis direction of the fixing shaft and extends in the direction of the end of the shaft body, and the stator supports abut against and is connected to the fixing part. According to the fixing shaft of the generator and the wind driven generator comprising the same, the fixing part is arranged at the end part of the middle flange of the fixing shaft, so that the supporting platform used for supporting and fixing the stator is provided, and the supporting platform protrudes out of the middle flange along the axial direction; the structure rigidity of the connecting end of the middle flange and the stator support is enhanced, and a larger area is provided for fixing the stator support, so that the fixing effect of the stator support is ensured, and the supporting effect is better.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a fixed shaft of a generator and a wind power generator including the same. Background technique [0002] For direct-drive wind turbines, there are generally two ways to set up the bearing structure: a single large bearing structure direct drive generator and two small bearing support structure generators. The large bearing structure is mainly supported by a large main bearing, and the wind wheel load of the wind turbine is transmitted from the main bearing to the fixed shaft. The structure supported by two small bearings is that one is arranged between the front end of the rotating shaft and the front end of the fixed shaft, and the other is arranged between the rear end of the rotating shaft and the fixed shaft. Compared with a single large bearing, the support method of two small bearings distributes the load to the two bearings, so that the two bearings share the load, s...
