Abstract
The utility model discloses a kind of novel axial flow impellers, the several blades including wheel hub and being circumferentially evenly arranged on the outside of wheel hub, wherein blade are detachably connected with wheel hub, and axis hole is equipped at the center of wheel hub, the outside of wheel hub is spherical surface, and bottom end and the wheel hub of blade fit.The utility model is designed reasonably, simple in structure, easy for assemble or unload, blade is completely embedded with wheel hub, is not in deflection distortion during use, is prolonged the service life, and ensures normal production.
Description
Technical field
The utility model is specifically related to a kind of novel axial flow impeller.
Background technology
The blade of commercially available axial wheel is connected with wheel hub generally use taper mode, and stress compares upon the rotation of the blade
Greatly, blade angle is easily deformed, and is reduced the service life, and injury device is also easy to.
Utility model content
The purpose of this utility model is to provide a kind of novel axial flow impellers, to solve proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of novel axial flow impeller, including wheel hub and
The several blades being circumferentially evenly arranged on the outside of wheel hub, wherein blade is detachably connected with wheel hub, and is set at the center of wheel hub
There are axis hole, structural feature to be：The outside of wheel hub is spherical surface, and bottom end and the wheel hub of blade fit.
Preferably, the bottom end of blade is detachably connected by connecting screw and locking nut with wheel hub, wherein connecting
Screw is wholely set with blade, and connecting screw runs through the side wall of wheel hub.
Preferably, blade is made of PVC or fiberglass.
Compared with prior art, the utility model is designed reasonably, simple in structure, easy for assemble or unload, blade connects with wheel hub
It connects closely, is not in deflection distortion during use, prolongs the service life, ensure normal production.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1- wheel hubs, 2- blades, 3- axis holes, 4- connecting screws, 5- locking nuts.
Specific implementation mode
Explanation is further explained to the utility model below in conjunction with the accompanying drawings, but does not limit the protection model of the utility model
It encloses.
In the description of the present invention, it should be noted that term "upper", "lower", "left", "right", "inner", "outside" etc.
The orientation or positional relationship of instruction is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model
It is described with simplifying, does not indicate or imply the indicated device or element must have a particular orientation, with specific orientation structure
It makes and operates, therefore should not be understood as limiting the present invention.
Referring to Fig. 1, the utility model provided a kind of technical solution, a kind of novel axial flow impeller, including wheel hub 1 and along week
To the several blades 2 for being evenly arranged in 1 outside of wheel hub, wherein blade 2 is detachably connected with wheel hub 1, and is set at the center of wheel hub 1
There is axis hole 3, the outside of the wheel hub 1 is spherical surface, and bottom end and the wheel hub 1 of blade 2 fit.
Wherein, in the present embodiment, the bottom end of the blade 2 can with wheel hub 1 by connecting screw 4 and locking nut 5
Dismantling connection, wherein connecting screw 4 are wholely set with blade 2, and connecting screw 4 runs through the side wall of wheel hub 1.
Wherein, in the present embodiment, the blade 2 is made of PVC or fiberglass.
The operation principle of the utility model：Wheel hub 1 uses spherical design, belongs to positive spherical surface, bottom end and the wheel hub 1 of blade 2
It fitting and spherical design, belongs to cloudy spherical surface, the positive spherical surface of the cloudy spherical surface and wheel hub 1 of blade 2 fits like a glove when assembling,
360 ° any one angle is entirely to fit like a glove, and blade 2 and 1 contact area of wheel hub are big, and frictional force is also big, and blade 2 is pre-
The connecting screw 4 buried is connect with wheel hub 1, and after fastening, blade 2, which rotates, will not change angle.
The utility model is designed reasonably, simple in structure, easy for assemble or unload, blade 2 is completely embedded with wheel hub 1, is used
Be not in deflection distortion in journey, prolong the service life, ensures normal production.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen
All changes in justice and range are embraced therein, and should not any reference numeral in claim be considered as limitation
Involved claim.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiment being appreciated that.
