In the prior art, the support 3 and the stator housing 1 need to be provided with holes, and because the thickness of the stator housing 1 is smaller, the stress of the stator housing 1 needs to be dispersed, the diameter of the holes is limited, and the number of the holes is more. Meanwhile, the matched holes damage the tightness of the stator housing 1, and the support 3 needs to be filled and repaired after being removed.
Disclosure of Invention
The utility model aims to solve the technical problems that: how to avoid the problem of damage to the tightness of the stator housing caused by punching holes in the stator housing.
In order to solve the technical problems, the technical scheme of the utility model provides a large-scale motor integral transportation stator and rotor fixing bracket which comprises a bracket, wherein one end of the bracket is fixedly connected with a rotor.
Preferably, the wing plates and the stator casing are welded into an integral structure.
Preferably, the fastener comprises a bolt, and the other end of the bracket is connected with the wing plate through the bolt.
Preferably, the side of the bracket connected with the wing plate is provided with grooves, keys are arranged in the grooves, the centers of the keys are provided with through holes, and bolts penetrate through the through holes of the keys.
Preferably, one end of the key is in transition fit with a groove on the bracket, and the other end of the key is in transition fit with a groove on the wing plate.
Preferably, the key is of a cylindrical structure, and the bolt between the bracket and the wing plate is coaxial with the key.
The utility model is used for fixing the stator and the rotor of the large motor, so that the stator and the rotor do not generate relative displacement in the transportation process, and the tightness of the stator shell is not damaged. The utility model has the advantages that at least one of the following points is:
1. fewer fasteners can be used, so that the fixed support and the stator shell of the large motor are firmly fixed;
2. the main load is transmitted through the key, so that the connecting bolt is prevented from shearing force;
3. the key is sleeve-shaped, and the required installation space is small;
4. the fixed support is connected with the stator housing through the wing plates, and holes are not required to be directly formed in the stator housing, so that the stator housing can be prevented from being damaged.

Detailed Description
In order to make the utility model more comprehensible, preferred embodiments accompanied with figures are described in detail below.
The utility model provides a stator and rotor fixing bracket for integral transportation of a large motor, which comprises a bracket 3, a key 4 and a wing plate 5, wherein the wing plate 5 is welded with a stator shell 1 into a whole, one end of the bracket 3 is fixedly connected with a rotor 2 (in the embodiment, the embodiment is the same as the prior art, namely, a hole on a rotor coupler is used between the rotor 2 and the bracket 3, and the bracket is connected with the wing plate 5 through a bolt), and the other end of the bracket 3 is fixedly connected with the wing plate 5 through the bolt. The support 3 all opens the groove on the one side that is connected with pterygoid lamina 5, and the inslot is equipped with key 4, and key 4 is cylindric structure, and open at the center promptly has the through-hole, and the bolt passes from the through-hole of key 4, and the transition fit in the groove on the support 3 of key 4 one end, the transition fit in the groove on the pterygoid lamina 5 of key 4 other end. The bolts between the bracket 3 and the wing plate 5 are concentric with the key 4.
The principle of the utility model is as follows:
the main load (parallel to the contact surface of the bracket 3 and the wing plate 5) between the bracket 3 and the key 4 is transmitted through the key 4, and the key 4 cannot fall off, so that the connection is more reliable, and the load caused by the axial acceleration of the rotor 2 in the transportation process can be overcome by using a small number of keys 4, so that the device is simple and compact; in addition, the structure of the utility model uses the wing plate as transition, thereby avoiding damaging the tightness of the stator housing.
