Abstract
The utility model relates to a taper sleeve fixing structure and a material conveying fan, wherein the taper sleeve fixing structure comprises a taper sleeve (1) with a convex ring or a convex lug and a taper shaft disk (2) corresponding to the taper sleeve (1), as well as a tightening bolt (4); furthermore, tightening bolt through holes are arranged on the convex ring or the convex lug of the taper sleeve (1) and the taper shaft disk (2) respectively. By using the taper sleeve fixing structure, an impeller of the fan can be arranged into or detached from a fan shaft in an easy, reliable and time-saving manner, and the interference fit between the impeller of the fan and the fan shaft is unnecessary during the mounting process, so that knocking is not required and the possibility of damages to a bearing is low.
Description
Technical field
The utility model relates to the blower fan technical field, relates in particular to a kind of impeller of material handling fan and the fixed structure and the material handling fan of axle.
Background technique
In blast system, material handling fan is essential as the capital equipment of air-transport system, when wind wheel damages, former wind wheel must be pulled down maintenance or changes, and because of the workload of dismounting fan blade is big, length consuming time influences the Homes Using TV of whole air-transport system.
Shown in Fig. 1-2, the fixation method of blower fan routine is draught fan impeller and blower fan axle interference fit at present.Draught fan impeller is packed into for this and to split out workload big, and length consuming time influences the Homes Using TV of whole system operation, damages bearing simultaneously when installation is knocked easily.
Summary of the invention
(1) technical problem that will solve
Technical problem to be solved in the utility model is: how to make the draught fan impeller blower fan axle of packing into very easily; Draught fan impeller can be removed from the blower fan axle easily, further, the utilization rate of material handling fan is improved, improve the manufacturing efficiency of man-made board.
(2) technological scheme
For achieving the above object, the utility model adopts following technological scheme.
The utility model provides a kind of tapered sleeve fixed structure, comprises tapered sleeve and its corresponding tapering reel and tight fixed bolt with bulge loop or lug, and is provided with the tight fixed bolt through hole respectively on the bulge loop of described tapered sleeve or lug and tapering reel.
Preferably, described tapered sleeve fixed structure also comprises liftout bolt, and is provided with the liftout bolt through hole at described tapered sleeve or tapering reel.
Preferably, described tight fixed bolt and liftout bolt are respectively two of equally spaced distributing or more than two.
The utility model also provides a kind of material handling fan, has as any the tapered sleeve fixed structure in the above-mentioned tapered sleeve fixed structure.
(3) beneficial effect
Use tapered sleeve fixed structure of the present utility model can be very light, reliable, draught fan impeller is packed into with saving time or splits out the blower fan axle, and in installation process, do not need interference fit between draught fan impeller and the blower fan axle, thereby do not need to knock and then be not easy to damage bearing.
Description of drawings
Fig. 1 is the draught fan impeller of prior art and the fixed structure side view of blower fan axle;
Fig. 2 is the draught fan impeller of prior art and the fixed structure plan view of blower fan axle;
Fig. 3 is the tapered sleeve fixed structure side view according to a kind of mode of execution of the utility model;
Fig. 4 is the tapered sleeve fixed structure plan view according to a kind of mode of execution of the utility model.
Embodiment
The tapered sleeve fixed structure that the utility model proposes is described in detail as follows in conjunction with the accompanying drawings and embodiments.
As shown in Figure 3-4, tapered sleeve fixed structure according to a kind of mode of execution of the utility model, comprise tapered sleeve 1, tapering reel 2, liftout bolt 3 and tight fixed bolt 4, wherein, tapering reel 2 endoporus are made internal taper hole, and cooperate with the external cone of tapered sleeve 1, cooperating between tapered sleeve internal diameter and the blower fan main shaft external diameter is Spielpassung.Tapered sleeve 1 is installed on the blower fan axle after being nested together with tapering reel 2 again, be provided with two or more tight fixed bolt through holes on tapered sleeve 1 and the tapering reel 2 respectively accordingly, on tapered sleeve 1 or tapering reel 2, be provided with the through hole that two or more liftout bolts 3 are passed with internal thread.
When draught fan impeller being packed into the blower fan between centers, owing to certain interval is arranged, the blower fan axle of can very like a cork draught fan impeller being packed between the tapered sleeve 1 of the hole of the tapering reel 2 of draught fan impeller and blower fan axle.After draught fan impeller arrives the mounting point, tighten tight fixed bolt 4, divide the tapered sleeve 1 on the arbor to move to draught fan impeller, the endoporus of tapering reel 2 shrinks on the draught fan impeller, reaches fastening purpose.Whole loading procedure easily, reliable, save time.
Similarly, with draught fan impeller when the blower fan axle splits out, earlier loosening tight fixed bolt 4 is screwed into liftout bolt 3 in the screw hole on branch arbor epicone cover 1 or the tapering reel 2 then, with the former tapering reel 2 top pines that are fastened on the tapered sleeve 1, draught fan impeller just can easily take out.Whole split out process easily, reliable, save time.
Above mode of execution only is used to illustrate the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technological schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
Claims (5)
