Abstract
The utility model discloses an industrial fan, which is composed of a motor and a fan; wherein the motor comprises a stator, a shell, a rotor and a motor shaft connected with the fan; the shell is composed of a front shell and an installation stator shell which is corresponding to the front motor shell; the front shell is composed of three or more hollow support components with nicks used for positioning the stator; the inner wall of the front shell is provided with a stand at the bottom, and the stand is provided with a cavity used for arranging a bearing. The stand and the front shell are integrated into one entity by punching. The utility model is simple in structure, thereby greatly reducing manufacturing cost of products; meanwhile the utility model avoids an opening end which clips the front shell in an inverted way when in processing, thereby providing convenient processing and effectively ensuring installation accuracy of the stator and overall appearance of products.
Description
Technical field
The utility model relates to a kind of industrial fan.
Background technology
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 pedestal of conventional motors shell is a through hole, must realize axial location with bearing (ball) cover during Bearing Installation, but the end cap installing hole adds the openend 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 accuracy 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, and a kind of simple in structure, industrial fan that cost is low and easy to process is provided.
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 at least three hollow support, has the breach that is used for the stator location on the strutting piece.
The inwall bottom of the outer fore shell of described motor is provided with pedestal, has to be used for bearings mounted cavity the outer fore shell integrated punching moulding of pedestal and motor on the pedestal.
Described strutting piece is provided with stator the corresponding screw of location hole on the back cover flange is installed.
Described strutting piece welding is fixed on the inwall of the outer fore shell of motor.
The utility model improves the industrial fan of prior art, but outside motor, be provided with the hollow support of fixed stator on the fore shell, fore shell is installed and stator is installed the motor housing that back cover is configured for ccontaining stator and rotor with motor, simple in structure, greatly reduce the manufacturing cost of product.Meanwhile, the outer fore shell of motor bottom be used for bearings mounted cavity with motor outer before shell opener in the same way, avoided adding the openend of clamping motor housing of commutating man-hour, easy to process, effectively guaranteed the installation accuracy of stator and the overall appearance of product.
