Description
Technical field
The utility model is related to a kind of wind wheel of cooking-fume exhauster axle sleeve, particularly a kind of fume exhauster for exempting from rivet installation
Wheel axle sleeve.
Background technology
Referring to Fig. 9 to Figure 11, current wind wheel of cooking-fume exhauster generally comprises blade assembly 7, wheel hub 5 and axle sleeve 20, blade
Component 7 is connected to the periphery of wheel hub 5, and axle sleeve 20 is arranged on the center of wheel hub 5.Axle sleeve 20 includes the disk for being used to be connected with wind wheel hub 5
Body 8 and it is used for and drive shaft（Motor shaft）The cylinder 9 of socket, cylinder 9 is with disk body 8 by aluminium integrally casting shaping.Cylinder 9 is located at
On the center of disk body 8, the center of cylinder 9 is provided with axis hole 91, and axis hole 91 coordinates with driving shaft clearance.Due to the wall thickness about 5mm of cylinder 9, and
And be straight-tube shape；Drive shaft is provided with spacing lateral pin, and driveshaft end is passed provided with connection thread, drive shaft from the bottom of axis hole 91
It is connected afterwards with locking nut, axle sleeve 20 is pressed between spacing lateral pin and locking nut.The disk body 8 is provided with connecting hole 82,
Connecting hole 82 is riveted by rivet 6 and wheel hub 5 and fixed, and because rivet 6 is also one of cost of product, therefore, is connected by rivet 6
Connect, also cause product cost to improve.
Further, since the casting of axle sleeve 20, easily there are sand holes in it, if sand holes appear in internal or fail to be found
When, it will its structural strength is had influence on, is easily broken off.Moreover, the rough surface of axle sleeve 20 come is cast out, and axis hole 91 is smooth
Degree is not enough, therefore, it is also desirable in mechanical process, machining process, it is impossible at the position of the surface indentation 81 of disk body 8
Reason, so that the position of the surface indentation 81 of disk body 8 is coarse unglazed, influences the overall appearance of product, simultaneously as aluminium price compared with
Height, and manufacturing procedure is various, so that its cost is greatly improved, is unfavorable for market competition.
Further, because the bottom of cylinder 9 is externally provided with the spacing lateral pin two ends in one group of locating slot 83 diametrically, drive shaft
It is undertaken on respectively on this group of locating slot 83.Because locating slot 83 only has one group, so, the spacing lateral pin of drive shaft is aligned therewith
It is cumbersome.
Further, due to there is gap between axis hole 91 and drive shaft, so, the center of axis hole 91 can not be weighed with shaft center
It is folded, thus it is uneven during wind wheel rotation, therefore, after wind wheel is connected with drive shaft, need to set counterweight block thereon.But it is above-mentioned
The installation of counterweight block is completed before product export, after wind wheel comes into operation, if because of smoke exhaust ventilator maintenance, cleaning etc.
In the case of wind wheel is dismantled after and when installing again, because the differential location of the center of axis hole 91 and shaft center is not each
Install all, so, very high probability causes wind wheel loss of equilibrium again（Or balance more serious）, so that reduce its effect and
Service life.
In summary, the deficiency of current axle sleeve is summarized as follows：1st, aluminum：Material cost is high；2nd, Vehicle Processing is needed：Precision
It is difficult to control, uniformity is not good, and is easy to scrap；3rd, extrusion process：The process characteristic of casting is exactly that density is not uniform enough, right
For needing to do dynamically balanced revolving parts in one, inherently defect；4th, intensity：The hiding gas hole defect due to having,
It is difficult to ensure that very reaching intensity；5th, surface：Because Vehicle Processing will not carry out secondary operation, and die casting to each face of part
The reason for release agent residue, cause the uniformity for being surface-treated difficulty very big and outward appearance not good；6th, yield：The limitation of technique is led
It is difficult lifting to cause production capacity；7th, connect：Need rivet.
