Embodiment Construction
[0012] The tooth pressure plate for pressing the stator and rotor iron core of a large motor includes a tooth pressure plate body, the pressure plate body 1 of the tooth pressure plate body is provided with a side facing the opposite side of the tooth bead 2, and a lamination groove 4 penetrating with this side; The connecting hole 3 is located in the laminated groove 4 .
[0013] The tooth pressure plate is a high-strength alloy steel tooth pressure plate. The root of the lamination groove 4 is arc-shaped chamfered. The thickness of the tooth bead 2 is the sum of the thickness of the pressing plate body 1 and the deformation of the lamination groove 4 under the lamination pressure (ie the depth of the lamination groove 4), and the depth of the lamination groove 4 ranges from 1 to 6 mm.
[0014] When in use, two tooth pressing plates 7 are respectively placed on both ends of the laminated silicon steel sheet 6, and the lamination groove 4 is arranged inwardly facing each othe...
