Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-2, a shaft disc includes a shaft sleeve 1 matched with an external motor shaft, a horn-shaped disc body 2 is fixed on the shaft sleeve 1, and the disc body 2 is a stamping part.

In practical application, the disc body 2 is produced in a stamping mode, and then the disc body 2 is fixed on the shaft sleeve 1 to realize the production of the shaft disc, so that the traditional casting production mode is replaced, and the production cost is reduced.

Preferably, the tray body 2 comprises a first connecting part 21 connected with the shaft sleeve 1, a second connecting part 22 used for being connected with an external fan wheel tray, and a horn part 23 connected between the first connecting part 21 and the second connecting part 22; the second connecting portion 22 is connected to the thick end of the horn portion 23.

In this embodiment, the first connecting portion 21 and the shaft sleeve 1 are connected by welding, so that the connecting performance is good, the structural rigidity is high, and the reliability of the shaft disc is ensured.

In this embodiment, the second connecting portion 22 is an annular body connected to the edge of the thick end of the horn portion 23, and the annular body is provided with a plurality of connecting holes 25;

specifically, the fan wheel disc is provided with a mounting hole adapted to the connecting hole 25, the external fan wheel disc is fixed to the second connecting portion 22 through a bolt connection, the number of the connecting holes 25 may be 4, 6 or more, and this embodiment does not limit this.

In this embodiment, the horn portion 23 is provided with a plurality of through holes 24 for passing an external puller;
