Supporting bracket for reducing horizontal shaking of motor

A supporting bracket for reducing horizontal shaking of a motor disclosed by the present invention comprises an end cover, a damping ring and a supporting bracket, a groove is formed in the top of the end cover, a second convex column is vertically installed at the center of the top of the groove, a first convex column is vertically installed at the center of the top of the second convex column, and the damping ring sleeves the surface of the first convex column. The supporting support is connected to the surface of the second protruding column in a sleeving mode and rotationally connected to the surface of the second protruding column, and a limiting mechanism used for limiting the supporting support is arranged in the groove of the end cover. The connecting medium supporting bracket is additionally arranged between the damping ring and the end cover, so that the shaking of the motor in the horizontal direction can be reduced, and the bottom of the damping ring is directly matched with the upper part of the
