Abstract
A kind of cylindrical rotor with multiple-blades cross flow fan, its solid rotating shaft setting-in is fixed in ring stand or the hub of plate core with extrusion process formation, blade is inserted in the blade insertion groove on ring stand week side, the width of those grooves is slightly larger than the thickness of blade, and be provided with in the inner end of those grooves part and cut the sky part, vent is arranged between groove, after in the blade insertion groove, with the outer rim of plate roller ca(u)lk, make the insertion groove compression of interlobate vent and blade when the outer end of blade is coated and the blade crimping is fixed in the groove.Advantage is that turning axle assembling back only needs meticulous centering center, and blade inserts and makes things convenient for assembly firm, and the product homogeneous can cheap a large amount of production.
Description
The present invention is that changes in temperature gas room is used or the cross-flow type fans interior dress of office machine usefulness and other wide cuts air-supply usefulness.
This that has kind of fan earlier, be used in every profession and trade as mentioned above widely, but on producing for the blade and the relation of assembling ring stand or the plate and the blade insertion groove of this blade, and the assembling formality of the hub that is assembling the onboard turning axle that on this hub, is assembling side by side and proofread and correct with one heart etc. and can not satisfactorily carry out, this all is a shortcoming.
Set out by the above-mentioned fact, in order to obtain satisfactory cross flow fan, fasten pass between ring stand that is assembling blade or plate, there is machining clearance to reduce a little earlier in order to make, as shown in Figure 3 make the insertion groove of blade (2) (3) identical with vane thickness, insert the words of blade, blade can fully seamlessly clip in insertion groove, but on actual techniques, insert difficulty,, can obtain the result of deformable blade and so on the contrary no matter all ground are pressed into toward insertion groove, do not have uniformity concerning product, working efficiency has just reduced certainly.
Also have, concerning the relation of plate (1 ') and turning axle (7), have earlier as shown in Figure 7, assembling hub (6) onboard, in this hub bore, turning axle is being inserted, be screwed, plate is carried out the center centering of turning axle, again, make fan not produce rotary vibration and normally rotating words, need considerable manual processing.
The objective of the invention is to propose to solve the means of above-mentioned variety of problems.Below by embodiment, the present invention will be described with reference to accompanying drawing.Wherein:
Fig. 1 is the front elevation that shows cross flow fan of the present invention, and a part is cut,
The same right hand view of Fig. 2,
Fig. 3 is the explanatory drawing of prior art,
Fig. 4 is the explanatory drawing of blade of the present invention and blade insertion groove and roller ca(u)lk,
Fig. 5 A, B are the sectional views that plate 2 embodiments of turning axle are housed,
Fig. 6 is the explanatory drawing of the fan after on the body of the plate that is installing turning axle blade being packed into,
Fig. 7 shows the front elevation that concerns between the plate that has earlier and hub and the turning axle.
Ring stand as shown in Figure 4 (1) and plate (1 ') also are same, but make the insertion groove (3) of its all side upper blades (2) insertion usefulness wideer a little than the thickness of blade, and the inner end portion of insertion groove is provided with and cuts empty part (4), between insertion groove, run through again slightly rounded or rectangular vent (5) is being set near the place of an insertion groove, so that the blade that inserts to the insertion groove of this ring stand (1) inserts easily, after blade inserts, by false ca(u)lk, at first blade is clipped in insertion groove, follow the ca(u)lk of suppressing by roller R, utilize the intensity of vent (5) part to be weakened, vent and squish lip are being pressed with blade to insertion groove together to be contacted, securely vanes fixed in ring stand, constitute columnar fan F.Then, in the outside of ring stand, as Fig. 1, Fig. 2, image pattern 5A, B by hub (6) is made in the central part extrusion process of plectane, in this, turning axle (7) inserted and fixing, just finished the assembling of plate (1 ').
And, shown in Figure 6 and as described above in ring stand, blade inserted set after, the plate that turning axle is housed on ring stand again is different, on the outer circumferential face of the plate that is fixed with turning axle (7) (1 ') itself, carry out the such blade of Fig. 4 assembling processing, blade directly is assemblied in a kind of like this fan on the ring stand (1).
The present invention is as described above on the formation of fan body, as shown in Figure 3, described like that the relation of blade and ring stand or plate with the solution of reference Fig. 4, the insertion groove of blade than the thickness of blade do wide certain degree, blade is inserted easily, be provided with in the inner end of insertion groove again and cutting empty part (4), make blade insert the depths, the inside easily, in addition, during the roller ca(u)lk, establishing vent (5) at the Bian Shangzhan of blade insertion groove, this part is because compression easily, crunch by the roller ca(u)lk, vent is enlarged, and because insertion groove (3) also compresses, blade can by strong ground build-in, the effect that can obtain, simultaneously, relation for turning axle (7) and plate (1 '), as Fig. 5 and different with first anything (referring to Fig. 7) as shown in Figure 6, originally make hub (6) with the plate one by extrusion process and so on one's body at plate, in this hub,, so just finished the assembling of fan carrying out necessary center centering retrofit after turning axle (7) assembling.And have uniformity and can produce in a large number.Particularly originally directly assemble blade (2) on one's body at plate as shown in Figure 6, with the hub (6) of plate one in turning axle (7) is inserted fixing simple structure, can produce the such fan of cylindrical rotor with multiple-blades of desirable cross flow fan cheaply, particular significant effect.
Claims (3)
1, a kind of fan of cylindrical rotor with multiple-blades, it constitutes a plurality of vane group is contained on the ring stand of both sides and centre, constitute columnar multi blade fan, feature of the present invention is, blade on all sides of this ring stand is inserted the insertion groove of usefulness, make wideer than the thickness of blade, so that blade inserts easily, and be provided with in the inner end of insertion groove part and cut the sky part, and between the blade insertion groove, account for and establishing vent circular or rectangular suitable size, after blade inserted in insertion groove, make the outer rim roller ca(u)lk of ring stand, when the blade outer end is coated, make the insertion groove compression of interlobate vent and blade, each vanes fixed of inserting in insertion groove, is equipped with the plate of turning axle on the ring stand of both sides.
