Abstract
The utility model discloses an industrial fan, which comprises a motor and vanes. The motor comprises a shell, a stator, a rotor and a motor shaft connected with vanes; the shell of the motor comprises an outer front shell of the motor and a stator installation back shell. The stator is mounted on the inner wall of the motor outer front shell; a port of the stator installation back shell is provided with a rolled edge; an end surface of the stator is provided with a step matching the rolled edge of the stator installation back shell. The utility model greatly saves the manufacture materials of the stator and the rotor installation back shells and reduces production cost of product. The installation of the product is convenient and simple, which is helpful to improve the overall accuracy of the products.
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, the industrial fan that the outer fore shell of a kind of motor is stamping part has appearred in the improvement technology, the basic structure of its motor comprises outer fore shell of motor and stator installation back cover, stator is realized being fixedly mounted in the cavity of two housings formation by the positioning convex thing on the two housings inwall, and more traditional to a certain extent industrial fan has alleviated weight.But the stator of this kind fan is a column structure, and its external diameter is everywhere all with suitable with the inner diameter of two housings.Yet, the motor of this structure, its stator and stator are installed back cover and are still existed the space that can save material, and, for guaranteeing the installation precision of stator, outer fore shell of motor and stator install back cover must on lathe, process with guarantee two-port etc. in through requiring and the circularity requirement, manufacturing procedure bothers, and has increased the manufacture cost of product, and, slippage appears in the craft port place of two housings easily after the connection, the installation precision that influence is actual.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of material, cost industrial fan low and easy for installation saved 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 outer fore shell of motor and stator installation back cover, stator is installed on the inwall of the outer fore shell of motor, and the port that stator is installed back cover is provided with the flange outer, it is characterized in that: have on the end face of described stator with stator the step that the flange outer of back cover matches is installed.
Described stator is installed to have on the flange outer of back cover and is used for the mounting hole that is connected with the outer fore shell of motor.
The outer fore shell of described motor bottom is provided with stator installs the screw hole that the mounting hole on the back cover flange outer matches.
The utility model improves the industrial fan of prior art, on the end face of stator, have with stator the step that the flange outer of back cover matches is installed, the diameter that the stator that matches is with it installed back cover also can dwindle, save stator and stator the manufactured materials of back cover has been installed, reduced the manufacture cost of product.In addition, when stator is installed the back cover installation, can realize relative positioning by flange outer on it and the step on the stator, product is easy for installation simple, the precision height.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is the structural representation of the utility model stator.
Accompanying drawing 3 is the structural drawing of the outer fore shell of the utility model motor.
Accompanying drawing 4 has the structural representation of back cover for the shell of the utility model motor.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
To shown in Figure 4, the industrial fan of the utility model comprises motor and flabellum according to Fig. 1, and motor is fixed on the base with a supporting rod usually.Wherein, motor comprises shell, stator 1, rotor and motor shaft, and an end of motor shaft is connected with rotor, and its other end stretches out the shell of motor and is connected with flabellum.And the shell of motor comprises the outer fore shell 2 of motor and with the stator that the outer fore shell 2 of motor matches back cover 3 is installed, for alleviating the overall weight of fan, outer fore shell 2 of motor and stator are installed back cover 3 and all be can be the impact briquetting part, and have corresponding radiation hole in bottom separately, simultaneously, it all be semiclosed shape structure that outer fore shell 2 of motor and stator are installed back cover 3, and both openings are installed relatively, and forming one can ccontaining stator 1 and the space of rotor.The inwall that outer fore shell 2 of motor and stator are installed back cover 3 is provided with the small lugs that is used for stator 1 location, stator 1 is installed in by small lugs on the inwall of the outer fore shell 2 of motor, and its extension is positioned at stator by corresponding small lugs equally and installs on the inwall of back cover 3.The port that stator is installed back cover 3 is provided with flange outer 31.Have on the end face of stator 1 of the present utility model with stator the step 11 that the flange outer 31 of back cover 3 matches is installed, as shown in Figure 2, the top external diameter of step 11 cooperatively interacts with the internal diameter of stator installation back cover 3.Stator is installed to have on the flange outer 31 of back cover 3 and is used for the mounting hole 311 that is connected with the outer fore shell 2 of motor, and outer fore shell 2 bottoms of motor are provided with stator the screw hole 21 that the mounting hole 311 on the back cover 3 flange outers 31 matches are installed, with screw connection hole 311 and screw hole 21, just can realize the installation of motor housing, as shown in Figure 1.For this reason, the diameter that stator is installed back cover 3 just can dwindle, and has saved the manufactured materials of stator 1 with stator installation back cover 3, has reduced the manufacture cost of product.During the fan assembling, only need earlier stator 1, rotor and motor shaft predetermined fixed fore shell 21 and stator outside motor are installed in the back cover 3 formed cavitys, with outer fore shell 2 of fastening piece fixed electrical machinery and stator back cover 3 is installed then, and outside motor, be equipped with back cover 4 on the fore shell 2, constitute the shell of the motor of band back cover 4, as shown in Figure 4.During this time, when stator is installed back cover 3 installations, can realize relative positionings by flange outer on it 31 and the step 11 on the stator 1, product is easy for installation simple, is beneficial to the overall precision of raising product.
