[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] As Figure 1-2 shown, a special flange for a permanent magnet motor with a worm and worm gear reducer includes:

[0019] The flange body 1, the flange body 1 is in a horn shape, a circular boss 2 is fixedly provided at the center of the flange body 1, a through bearing mounting hole 3 is provided at the center of the circular boss 2, the inner side of the bearing mounting hole 3 is in a stepped shape, a plurality of through reducer fixing holes 4 are provided on the flange body 1, a plurality of uniformly distributed connecting ears 5 are provided at the lower edge of the flange body 1, motor fixing holes 6 are provided on the connecting ears 5, a plurality of reinforcing ribs 7 are provided inside the flange body 1, and at least one reinforcing rib 7 is located between two adjacent reducer fixing holes 4; the horn-shaped flange body 1 and the connecting ears 5 are arranged, which can make the insertion and screwing process of the bolts more convenient, and can effectively reduce the installation difficulty caused by the proximity of the motor or the reducer. Optionally, one reinforcing rib 7 is arranged between two adjacent reducer fixing holes 4, so as to effectively improve the strength of the connection part.

[0020] In this embodiment, specifically, the circular boss 2 penetrates the flange body 1, one side of the reinforcing rib 7 is connected to the inner side wall of the flange body 1, the other side of the reinforcing rib 7 is connected to the outer side wall of the circular boss 2, and the horizontal sides of all the reinforcing ribs 7 are located on the same horizontal plane.
