A kind of fixed support for Axial-flow fan motor
Technical field
the present invention relates to a kind of fixed support for Axial-flow fan motor.
Background technique
the fixation method of existing Axial-flow fan motor mainly by Flange joint on the fitting seat of motor housing or motor end face, the cost of this method is higher.Because the seismism produced during vane rotary is also very serious, thus cause the shake of fitting seat to produce very large noise, shake frequently can cause contact segment to rupture, and affects working life.
the guide plate be generally used on axial-flow blower is fixed guide plate, and the distance between guide plate and impeller is non-adjustable, cannot form best fit with impeller, can not make the optimized performance of axial-flow blower.
Summary of the invention
the object of this invention is to provide the fixed support for Axial-flow fan motor that a kind of structure is simple, with low cost, position is adjustable.
for achieving the above object, the technical solution used in the present invention is:
a kind of fixed support for Axial-flow fan motor, described axial-flow blower comprises outer surface and offers the motor of T-slot, the impeller be connected on described motor output shaft vertically, described fixed support comprises dismountable fixing part be connected in described T-slot, for supporting the supporting portion of described motor, one end of described supporting portion is fixedly connected on described fixing part, and described fixed support also comprises the pedestal be fixedly arranged on the other end of described supporting portion.
preferably, the bolt that what the described fixed support length direction also comprised along described T-slot slided be arranged in described T-slot, the nut matched with described bolt, what described bolt comprised cooperation snaps in the bolt head in described T-slot, the stud be connected on described bolt head, described fixing part offers the through hole coordinating described stud to pass, the setting that described fixed support and described motor are interfixed by described bolt and described nut.
preferably, described fixed support is also provided with guide plate.
preferably, described supporting portion is provided with the first stiffening rib along its length.
preferably, the joint of described supporting portion and described fixing part is provided with the second stiffening rib.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: a kind of fixed support for Axial-flow fan motor of the present invention, fixing rack structure is simple, with low cost, by bolts and nuts, fixed support is fixed in the T-slot on motor surface, adjusting the fixed position of fixed support in T-slot as required, because guide plate is arranged on fixed support, impeller can being coordinated to make fan performance optimization by regulating support bracket fastened position.

Embodiment
below in conjunction with accompanying drawing, technological scheme of the present invention is further elaborated.
shown in Fig. 1-4, above-mentioned a kind of fixed support 1 for Axial-flow fan motor, this axial-flow blower comprises outer surface and offers the motor 2 of T-slot 21, the impeller 3 be connected on motor output shaft vertically, this fixed support 1 comprises dismountable fixing part 11 be connected in T-slot 21, supporting portion 12 for support motor, one end of this supporting portion 12 is fixedly connected on fixing part 11, this fixed support 1 also comprises the pedestal 13 be fixedly arranged on the other end of supporting portion 12, this pedestal 13 can be shelved on the ground, also can be arranged on the position of needs installation.
in the present embodiment, fixed support 1 also comprises the bolt 14 be arranged in above-mentioned T-slot 21 of slip, the nut 15 matched with this bolt 14, this bolt 14 comprises the bolt head 141 snapped in T-slot 21 of cooperation, be connected to the stud 142 on bolt head 141, can slide along the length direction of T-slot 21 in the horizontal edge that this bolt head 141 is stuck in T-slot 21, the length of this stud 142 is longer than the vertical edge length of T-slot 21, this fixing part 11 offers the through hole 111 coordinating stud 142 to pass, when fixed support 1 interfixes with motor by needs, only need correct position bolt 14 being put into T-slot 21, then fixing part 11 is adjacent to along through hole 111 in T-slot 21 through stud 142, finally nut 15 is tightened on bolt 14.
in order to ensure the firm of connection, fixing part 11 can offer multiple through hole 111, in T-slot 21, putting into the identical bolt of quantity 14 simultaneously, making it be fixed together one to one by multiple nut 15.
in the present embodiment, this fixed support 1 is also provided with guide plate 4, by the adjustment fixed position of fixed support 1 in T-slot 21, the distance of the relative impeller 3 of guide plate 4 can be regulated to make the optimized performance of axial-flow blower.
the frequent shake produced when rotating to prevent impeller 3 causes contact segment to rupture, thus affects its working life, is provided with many second stiffening ribs 122 at the fixing part 11 of fixed support 1 with the attachment portion of supporting portion 12.
in order to make fixed support 1 better support motor, supporting portion 12 along its length on be provided with the first stiffening rib 121, this first stiffening rib 121 can have many.
the concrete working procedure setting forth lower the present embodiment below:
when needing fixed electrical machinery, first the two ends of bolt 14 on T-slot 21 length direction are slipped in T-slot 21, then suitable position is slid into, the through hole 111 of fixing part 11 is inserted in the stud 142 of bolt 14, then nut 15 is screwed into along stud 142, fixing part 11 is tightened in T-slot 21, is fixed on motor by fixed support 1.
above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
