Description
Technical Field
The utility model relates to an axial compressor fan blade field especially relates to an assemble axial compressor fan blade subassembly.
Background
The axial flow fan can generate airflow in the same direction as the axis of the fan blade, and the common blade type electric fan is a typical axial flow fan. Unlike centrifugal fans which focus on air pressure, axial fans are commonly used in applications where the requirement for air flow is high, such as pneumatic textile product conveying equipment.
One of the main components of the axial flow fan is an axial flow fan blade, the blade is fixed on a hub, and the hub and the blade are driven to rotate by a motor. The blade can weld on wheel hub or adopt the screw fixation on wheel hub, and the welding mode is although firm, but is difficult to dismantle the maintenance, has certain requirement to the material moreover, and needs the blade to have certain thickness when adopting the screw fixation, and the effort of blade can give the screw moreover, and the screw atress is great, and the reliability is difficult to guarantee.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an assemble axial compressor fan blade subassembly promotes to dismantle and maintains the convenience, ensures to assemble structural reliability.
To achieve the purpose, the utility model adopts the following technical proposal:
an assembled axial flow fan blade assembly, comprising: wheel hub, fan blade, axle sleeve, first fixed disk and second fixed disk, the concentric cover of wheel hub is established on the excircle of first fixed disk, the axle sleeve sets up in the hole of first fixed disk with one heart, the interval is provided with the several jack on the wheel hub, the fan blade distribute on the wheel hub excircle and with the jack one-to-one, be provided with on the fan blade and extend to the inboard inserted bar of wheel hub through the jack, the second fixed disk cover is established on the axle sleeve and is located the rear of inserted bar, be provided with the screw that is connected with the inserted bar on the second fixed disk.
Wherein, the jack is the shoulder hole, the inserted bar is the step shaft.
And a square groove is concavely arranged on the part of the side surface of the inserted bar, which is contacted with the second fixed disc.
And the hub and the shaft sleeve are respectively welded and fixed with the first fixed disc.
The second fixed disk is located behind the first fixed disk, and the inserted bar is located between the first fixed disk and the second fixed disk.
The fan blades are welded and fixed with the inserted rods.
The utility model has the advantages that: the utility model provides an assemble axial compressor fan blade subassembly, carries out the location of fan blade through the cooperation of inserted bar and jack, assembles the facility to utilize the contact of square groove and second fixed disk to avoid the torsion of the relative second fixed disk of inserted bar, reduced the atress of screw, promoted structural reliability.

Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1 to 3.
As shown in fig. 1, the assembled axial-flow fan blade assembly includes: wheel hub 1, fan blade 2, axle sleeve 4, first fixed disk 6 and second fixed disk 5, 1 concentric cover of wheel hub is established on the excircle of first fixed disk 6, axle sleeve 4 sets up in the hole of first fixed disk 6 with one heart, in this embodiment, wheel hub 1 and axle sleeve 4 respectively with 6 welded fastening of first fixed disk, the sound construction. The shaft sleeve 4 is connected with a rotating shaft of a motor, and the shaft sleeve 4 and the hub 1 are driven to rotate by the motor.
The fan blades 2 are distributed on the outer circle of the hub 1 and correspond to the jacks one by one, 3-12 fan blades 2 need to be installed, and 3-12 jacks are correspondingly processed. The fan blade 2 is provided with an inserted rod 3 extending to the inner side of the hub 1 through an insertion hole, in the embodiment, the fan blade 2 and the inserted rod 3 are welded and fixed, and the connection strength of the fan blade 2 and the inserted rod 3 is ensured. As shown in fig. 3, in the present embodiment, the insertion hole is a stepped hole, the insertion rod 3 is a stepped shaft, and the insertion rod 3 is positioned through the insertion hole, so that the insertion is convenient.
The second fixed disk 5 is sleeved on the shaft sleeve 4 and is located behind the insertion rod 3, and in the embodiment, the second fixed disk 5 is welded and fixed with the shaft sleeve 4, so that the structure is firm. And a screw 8 connected with the inserting rod 3 is arranged on the second fixing disc 5, so that the assembly and disassembly are convenient.
As shown in fig. 2, the second fixed disk 5 is located behind the first fixed disk 6, and the insertion rod 3 is located between the first fixed disk 6 and the second fixed disk 5, so that partial hiding of the insertion rod 3 is realized, and the integrity of the fan blade assembly is improved by matching the second fixed disk 5 with the insertion rod 3.
In order to avoid the torsion of the inserted bar 3, the part of the side surface of the inserted bar 3 contacting with the second fixed disk 5 is concavely provided with a square groove 7, and the inserted bar 3 is limited by the fit of the square groove 7 and the second fixed disk 5, so that the stress of the screw 8 is reduced, and the structural reliability is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention, and it is to be understood that the present invention is not limited to the above embodiments, but may be modified within the scope of the present invention.
