Abstract
The utility model relates to a wind wheel for a wind screen machine. The wind wheel is arranged at two ends of a motor. The wind wheel is characterized by comprising an impeller, a sleeve end plate, a shaft end plate and a bearing, wherein one end of the impeller is welded on the sleeve end plate and is connected with a motor shaft through the sleeve end plate and the other end of the impeller is welded on the shaft end plate and is supported on a shell of the wind screen machine through the bearing on the shaft end plate; and swing angles of blades on the impeller are unequal. The blades cannot be simultaneously stressed when pressing the air because various sections of impellers are mutually staggered during welding and the angles of the blades are changed, so that the blocking force of wind is reduced, the stability of the wind wheel and the stability of the motor are also improved, and the service life is also improved because the motor is uniformly stressed.
Description
Technical field
The utility model relates to wind wheel, particularly uses wind wheel about a kind of air curtain machine.
Background technique
Wind curtain machine also is the indispensable auxiliary products of air conditioner as a kind of modern energy-conserving product, often is installed on the doorway of market, theater, conference hall, hotel, office, factory, apotheca.The high velocity air that wind curtain machine produces is divided into two different temperature districts with indoor and outdoor, has both kept the benefit of room conditioning or warm braw, saves electric energy, can make air circulation again, effective dust, flue gas, foul smell and winged insect etc., thereby the indoor environment of Creating Comfort.
Existing air curtain machine, housing are rectangular, and are horizontal installation mostly, and wind wheel will be delivered to the exhaust outlet of housing bottom by the air-flow of housing front air intake suction, because the restriction of hull shape, the air channel is longer.While is equal angular arrangement mode because of the blade of its wind wheel again, can be simultaneously stressed when blade is pressed wind, and the resistance of wind is big, and the poor stability of wind wheel, the noise during machine operation are also big more.
Summary of the invention
To the problems referred to above, the utility model is devoted to improve the structure of wind wheel, provides a kind of air output big, and the air curtain machine that noise is low is used wind wheel.
For realizing above-mentioned purpose; The following technological scheme of the utility model: a kind of wind curtain machine is used wind wheel, is arranged on the two ends of motor, it is characterized in that: comprise impeller, cover end plate, axle head plate and bearing; Said impeller one end is welded on the cover end plate; Link to each other with motor shaft through the cover end plate, the other end is welded on the axle head plate, and passes through said bearings on the axle head plate on the wind curtain machine housing; Blade swing angle on the said impeller does not wait.
Said impeller is divided into multistage and welds together, and the several angle that misplaces mutually of the blade between each section impeller connects.
Said wind wheel is cylindric, between intake grill and exhaust outlet, makes and forms the semi-circle air channel in the Blower Housing.
The utility model is owing to adopt technique scheme; Have following effect: 1, the utility model places wind wheel at the two ends of motor; Make to form the semi-circle air channel in the housing, when wind wheel rotates, form positive negative pressuren zone preferably, the noise when reducing machine operation effectively.2, the utility model because of between each section impeller when welding mutual dislocation and blade angle thereby change can be simultaneously not stressed when making blade press wind, thereby reduce the stifled power of wind; Thereby also improve the stability of wind wheel; Thereby also improve the stability of motor; Thereby also make the stressed even raising of motor working life.
Description of drawings
Fig. 1 is a wind wheel welding erection drawing;
Fig. 2 is the blade row Butut of wind wheel.
Embodiment
Carry out detailed description below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, the utility model is arranged on the two ends of motor, comprises impeller 1, cover end plate 2, axle head plate 3 and bearing more than 4 parts.Impeller 1 one ends are welded on the cover end plate 2; Link to each other with motor shaft through cover end plate 2; The other end is welded on the axle head plate 3, and is supported on the wind curtain machine housing through the bearing of installing on the axle head plate 34, carries out dynamic balancing again after assembling, the welding well and improves the wind wheel stability of rotation.
The utility model is with the total length requirement of impeller 1 by wind wheel; Be divided into several sections, first section impeller at first pressed locating point and 2 welding of cover end plate, and later each section impeller is continuously welded to Len req by locating point position successively; Last one section impeller and 3 welding of axle head plate form wind wheel cylindraceous.
Misplace mutually several angle welding of blade between above-mentioned each section impeller makes between each section impeller the air intake angle different, and is not stressed simultaneously when making blade press wind as far as possible, thereby reduces the stifled power of wind.And each blade on each section impeller, blade angle do not wait (various angles are not as shown in Figure 2 given an example at this one by one) yet.
Can be simultaneously not stressed when thereby the variation of mutual dislocation and blade angle makes blade press wind when welding because of impeller, thus the stifled power of minimizing wind, the noise when reducing machine operation effectively; Wind wheel is evenly stressed in the time of also can making blade press wind, thereby improves the stability of wind wheel; Wind wheel is evenly stressed in the time of also can making blade press wind, thereby improves the stability of motor; Wind wheel is evenly stressed in the time of also can making blade press wind, thereby makes the stressed even raising of motor working life.
Claims (3)
1. a wind curtain machine is used wind wheel; Be arranged on the two ends of motor; It is characterized in that: comprise impeller, cover end plate, axle head plate and bearing, said impeller one end is welded on the cover end plate, links to each other with motor shaft through the cover end plate; The other end is welded on the axle head plate, and through the said bearings on the axle head plate on the wind curtain machine housing; Blade swing angle on the said impeller does not wait.
