The screw hole corresponds to the position of the through hole, and the connecting part is closely attached to the motor casing. On the outer wall of the motor, the external bolts pass through the corresponding screw holes and through holes on the ends of the two adjacent connecting parts to lock the mounting brackets together, so that the mounting brackets tightly hold the motor casing.

The above-mentioned connecting portion is an arc-shaped body, which is closely attached to the outer wall of the motor casing.

The above-mentioned connecting portion and the mounting portion are spaced apart from each other and are in a vertical relationship.

An installation hole is opened on the above-mentioned installation part.

The above-mentioned mounting brackets are evenly distributed on the outer wall of the motor casing.

The above-mentioned mounting bracket is integrally formed by low-carbon steel.

The above-mentioned mounting bracket is also suitable for being installed on the motor shaft.

The connecting part of the above-mentioned mounting bracket is directly welded on the motor shaft or welded on the bushing on the outer wall of the motor shaft, or is locked together by bolts and then tightly hoops the motor shaft.

The beneficial effects of the utility model are: 1) the support part on the mounting bracket is designed as a sheet-shaped twisted body structure, the manufacturing process is simple, the toughness and connection strength of the support part are increased, and there is no need to increase the material thickness of the mounting bracket itself or Adding reinforcing ribs can increase the structural strength of the entire motor mounting bracket, reduce the amount of consumables for the mounting bracket, and reduce the structural cost; 2) There are various installation and connection methods between the mounting bracket and the motor casing or the motor shaft, which is conducive to the installation of the mounting bracket. Diversified use; 3) The mounting bracket is integrally made of low-carbon steel, which is energy-saving and environmentally friendly.
