Abstract
A motor shell assembly of industrial fans comprises a pressed front motor cover, a rear motor cover, a motor shell and a fixed support shaft. The motor shell is in the shape of a high ball glass and a bearing hole is arranged at the bottom of the glass. The diameter of the glass opening of the motor shell is bigger than that of the glass bottom. The edge of the glass opening extends to form a convex edge to be fixed with the front motor cover, and the middle of the motor shell is provided with a supporting and fixing portion of a stator. The supporting and fixing portion comprises ribs disposed at the jointing position of bigger and smaller diameters of the motor shell and one end of the stator supports the ribs. By the adoption of the supporting and fixing portion added on the motor shell, the motor shell assembly achieves the purpose of speedy assembly of a stator and realizes the fixing of a stator without using other parts and components, thereby saving materials. Meanwhile the motor shell ensures the compactness of connection between a stator and a motor shell, thereby effectively avoiding eccentricity during assembly process, reducing shock, noise and abrasion. Therefore, manufacturing process is simplified and reject rate of products is lowered. The motor shell assembly has the advantages of being simple in structure, low in cost and easy to process and manufacture.
