Description
Technical field
The utility model belongs to Fan Equipment technical field, relates to a kind of fan blade for blower.
Background technique
High pressure blower, also be high pressure positive blower, its inside is provided with fan blade, when fan blade rotates, effect due to centrifugal force, wind vane impels gas outwards motion forward, thereby form a series of spiral helicine motions, air between fan blade blade accelerates in the shape of a spiral rotation and the gas outside the pump housing is clamp-oned to side channel, after its approaching side passage, gas is compressed, then be returned to again between impeller blade and again accelerate to rotate, the degree that each impeller blade has increased compression and accelerated, carrying out along with rotation, the kinetic energy of gas increases, the gas pressure passing through along side canal is further increased, final gas is extruded blade and discharges the pump housing by outlet.Current high pressure blower, except impeller outer, does not have other moving parts, and the direct connecting motor of impeller, and small-sized being easy to carry about with one is widely used in cooling etc. the general suction air-supply of printing machinery, burning machine, woodworking machinery, dryer, incinerator, machinery.
As Chinese invention patent application (application number: 201210505691.1) disclose a kind of impeller of electric blower, this impeller comprises: upper plate; Lower plate; And be arranged on the wheel blade between upper plate and lower plate, wherein, lower plate comprises flange part, this turn-up portion divide be formed on lower plate with axle plug-in type the inner-diameter portion whose that is connected.In addition, also disclose a kind of impeller of electric blower, this impeller comprises: upper plate; Lower plate; And be arranged on the wheel blade between upper plate and lower plate, wherein, lower plate comprises flange part and packing ring part, described turn-up portion divide be formed on lower plate with axle plug-in type the inner-diameter portion whose that is connected, described packing ring part is along the direction extension perpendicular to flange part.Yet above-mentioned impeller is all to adopt metallic material to make, and its weight is larger, and inertia is larger in the running, and larger weight also can affect the whole work efficiency of blower.
Summary of the invention
There are the problems referred to above for existing technology in the utility model, has proposed a kind of fan blade for blower, should be light for the fan blade quality of blower, can effectively improve the working life of fan blade and the efficiency that fan blade rotates.
The purpose of this utility model can realize by following technical proposal: a kind of fan blade for blower, comprise outer ring and joint, on the outer side wall outer side wall of described outer ring, be circumferentially evenly equipped with blade, it is characterized in that, described joint is plate-like, and described outer ring sleeve is located on the periphery wall of joint, and both are connected mutually, described joint offers center hole at home position, is fixed with the connecting sleeve for being connected with rotating shaft in described center hole, and described joint adopts carbon fibre material to make.
Outer ring and joint and connecting sleeve are fixed together and form a complete fan blade, but separate machined while producing, make processing technology simpler, joint is the main carrying position of fan blade, occupy larger weight and volume, therefore adopt carbon fibre material to make, carbon fiber is that a kind of carbon content is in more than 95% high strength, the tencel material of high modulus fibre, axial strength and modulus are high, density is low, higher than performance, without creep, superhigh temperature resistant under non-oxidizing atmosphere, fatigue resistance is good, be widely used in mechanical manufacturing field, adopting metallic material to make with whole joint compares, its longer service life, and weight is significantly reduced, the total quality of blower is reduced, reduce the inertia of fan blade simultaneously, improve rotational efficienty, moulding process restriction due to carbon fiber, therefore it is connected with rotating shaft by connecting sleeve.
At the above-mentioned fan blade for blower, on the madial wall of described outer ring, circumferentially offer annular connecting groove, described connecting groove is positioned at the width center of connecting groove, and the outer edge of described joint is connected in connecting groove, and described joint periphery wall and connecting groove inwall are connected by bonding.Connecting groove is positioned at the width center of connecting groove, makes integral body more symmetrical, and connecting groove is for being connected mutually with joint, both are bonding by glue, and such glue is more, as epoxy resin glue, thermal structure glue etc., are all comparatively existing binders, its join strength is higher.
At the above-mentioned fan blade for blower, described connecting sleeve adopts stainless steel material to make, and offers vertically a v notch v on connecting sleeve, and the periphery wall of connecting sleeve and the center bore inner wall of joint are connected by bonding.Because connecting sleeve need to be connected with rotating shaft, this structure is not suitable for adopting carbon fibre material to make, therefore adopt stainless steel material to make, stainless steel material mechanical strength is high, and it adopts Steel material to have larger intensity, can not get rusty, therefore can be good at coordinating carbon fiber to use, the bar v notch v of offering is for connecting locating stud etc., and then is connected with rotating shaft, and integral body can adopt impact briquetting.
At the above-mentioned fan blade for blower, the two ends of described connecting sleeve all circumferentially have annular against convex edge, the described sidewall against convex edge compresses mutually with joint sidewall, described one-body molded against convex edge and connecting sleeve.Against convex edge, for the miscellaneous part with the blower such as wind bucket and wind lid, act on mutually and coordinating, against convex edge, also joint is played to location fixation, make joint more stable with being connected of connecting sleeve simultaneously.
At the above-mentioned fan blade for blower, on described joint, circumferentially evenly offer some through holes.Through hole can reduce the use of carbon fibre material, also can alleviate the weight of fan blade.
Compared with prior art, this fan blade for blower has the following advantages:
1, because joint adopts carbon fibre material, make, adopt metallic material to make with whole joint and compare, its longer service life, and weight is significantly reduced, the total quality of blower is reduced, reduces the inertia of fan blade simultaneously, improve rotational efficienty.
2, can separate machined due to outer ring and joint and connecting sleeve, make processing technology simpler.
3, because joint is to be fixed in the connecting groove of outer ring, externally enclose axially locating, join strength is also higher simultaneously.
