An integrated ventilated tooth pressure plate

Abstract

The invention discloses an integrated ventilating type tooth support. The integrated ventilating type tooth support comprises an annular pressing ring, and a tooth support body which is prepared from metal material or nonmetal material; a plurality of screw mounting holes are formed in the pressing plate; the pressing ring and the tooth support body are integrally structured; a plurality of tooth support plates are arranged on the tooth support body; bulges are arranged at one of the sides of the tooth support plates, close to a stator / rotor punch; the height of each bulge is gradually increased from inside to outside; a closing groove corresponding to a stator / rotor punching groove is formed between every two tooth support plates. According to the integrated ventilating type tooth support, the integrated processing structure is adopted, thus the inaccurate deformation and positioning caused by welding can be avoided, and the processing quality can be improved; various ventilating channels can be formed through the structure as requirement, thus the air channels can be flexibly designed, and the problem of dispersing of teeth of the motor can be solved.

Description

technical field [0001] The invention belongs to the technical field of motor ventilation, and in particular relates to a novel integrated ventilation tooth pressure plate, which is suitable for motors with accurate size requirements, reliable structure, high adaptability to the air path structure of the tooth pressure plate, and easy installation. Background technique [0002] In the motor, the iron core of the stator and rotor is formed by laminating silicon steel sheets of about 0.5mm. The whole iron core forms a solid whole by tightening the screw. The two axial end faces of the rotor iron core cooperate with the pressure ring to tighten the laminated iron core; one is to lead out a special air path to cool the end of the stator and rotor of the motor. [0003] Under the current trend of compact and high-efficiency motor design, the tooth pressure plate structure must have the characteristics of high reliability and easy installation. At the same time, the structure of t...

Problems solved by technology

[0005] This structure has the following disadvantages: the welding workload is large; the size is difficult to guarantee due to large welding deformation, and the installation deviation is large; the contact surface between the pressure ring and the tooth pressure plate is difficult to ensure flatness, resulting in uneven pressing force; the pressure ring presses the yoke of the tooth pressure plate Causes the inter-teeth to scatter; the match between the tooth pressure plate and the overall air path is basically not considered, and even some structures increase the height of the brace to prevent the inter-tooth scatter, resulting in a short circuit of the air path
