Description
Technical field
The utility model relates to a kind of industrial fan.
Background technique
Traditional industrial fan, its motor housing and stator holder all are to adopt cast iron to process, and the weight of complete machine is big, and materials demand is more, and, the complicated trouble of manufacturing procedure, the processing cost height, precision is low, is difficult to satisfy requirements of mass production.For this reason, Chinese patent ZL200420093711.X discloses a kind of industrial fan, the fan of this structure, the outer fore shell of motor, the stator that its motor housing is formed by metal plate punching is installed by fore shell and stator installation back cover is formed, stator installation fore shell is arranged in the motor installation fore shell and with stator back cover is installed and is connected, and constitutes the space of a ccontaining motor stator and rotor.Yet, the described industrial fan of this patent, three motor housings that combine, complex structure, and also installation procedure is more, and processing cost is higher; Simultaneously, the bearing support of conventional motors shell is a through hole, must realize axially locating with bearing (ball) cover during Bearing Installation, but the end cap mounting hole adds the opening end of the clamping motor housing that must commutate man-hour, the manufacturing procedure trouble, and cause stator that the distortion of fore shell is installed easily, influence the installation precision of stator, be unfavorable for the overall appearance of product.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is low and firm industrial fan easy for installation.
Goal of the invention of the present utility model is achieved in that a kind of industrial fan, comprise motor and flabellum, wherein, motor comprises shell, stator, rotor and the motor shaft that is connected with flabellum, the shell of motor comprises the outer fore shell of motor and with the stator that the outer fore shell of motor matches back cover is installed, it is characterized in that: the outer fore shell of described motor is provided with the supporting element with the outer fore shell integrated punching moulding of motor, supporting element is provided with the annular slot that is used for the stator location, and the outer fore shell of motor bottom is provided with the bottom that tape spool holds installation cavity.
Described supporting element is provided with stator the corresponding screw of attachment hole on the back cover edge is installed.
The utility model improves the industrial fan of prior art, outer fore shell of motor and the supporting element integrated punching moulding that is used for the stator location, the bottom of the outer fore shell of motor then is provided with the bottom in Bearing Installation chamber, has simplified the structure of product greatly, has reduced the manufacture cost of product.And, bottom be welded on the outer fore shell of the motor of supporting element integrated molding on, easy for installation firmly, the manufacturing efficiency height has effectively guaranteed the installation precision of stator and the overall appearance of product.
