Description
Technical field
The present invention relates to machine field, refer more particularly to a kind of motor fan structure of rapid-assembling/disassembling.
Background technique
Motor converts electrical energy into mechanical energy or mechanical energy is converted to electric energy in running, transform portion transformation of energy along with energy in this process becomes thermal energy consumption to fall, the cumulative motor temperature that causes of heat constantly raises, but causes motor failure or life-span obviously to shorten destruction insulation or lubrication when arriving certain numerical value.Usually at motor rotating part device fan, fan drives air to brush heater in rotary course, partial heat is taken away after air and heater carry out heat exchange, thus reduce the speed that heater temperature raises or the balance reaching heat radiation and heating, finally make heater temperature stabilization, the permanent operation of favourable like this motor.
In current fan assembly process, conventional measure is for be connected fan and rotating shaft hot jacket or fan, rotating shaft, key etc., in connection procedure, the processing of countershaft cylindrical, fan endoporus is very strict, usually need to use external cylindrical grinding machine processing rotating shaft, with lathe in machining fan endoporus, to reach tolerance fit required precision, work efficiency is low; If hot jacket needs to make it to expand to fan heating in assembly process, need in process to expend the energy and many elapsed times; Also easily there is the industrial accidents such as scald.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art and provide a kind of structure simple, repair and replacement are convenient, the motor fan structure of practical rapid-assembling/disassembling.
The present invention realizes in the following way:
A motor fan structure for rapid-assembling/disassembling, is characterized in that: comprise base plate 1, and the middle part of described base plate 1 is provided with mounting hole 11, and described base plate 1 is provided with the split die casting shaft shoulder 2 matched with motor shaft; The described split die casting shaft shoulder 2 is shaping with base plate 1 integrated die-casting, and the split die casting shaft shoulder 2 is positioned on the bore edges of mounting hole 11; Gap is provided with between the described die casting shaft shoulder 2; The described die casting shaft shoulder 2 is provided with fixed hole 21; The surrounding of described base plate 1 is distributed with some fan blades 3; The top of described fan blade 3 is connected with connecting plate 4; The edge conjunction of described connecting plate 4 has some fixed plates 5; The quantity of described fixed plate 5 is identical with the quantity of fan blade 3, and position is corresponding; The top of described fan blade 3 is connected with the bottom of fixed plate 5; Described base plate 1 is provided with some adjusting holes 12.
Gap between the described die casting shaft shoulder 2 is 2-3mm.
Described fixed plate 5 is triangle.
Beneficial effect of the present invention is: structure is simple, decreases rotating shaft, fan mounting holes machining accuracy, decreases the energy consumption of heated fan, the time loss to be heated such as to decrease, can provided with fan quickly and easily; When dismounting, more simpler than the fan of hot jacket, only need to unclamp bolt and just easily can take out fan, avoid using drawbench or heating to remove fan, even scrap.
Accompanying drawing explanation

Fig. 2 structure worm's eye view of the present invention.
Embodiment
Now by reference to the accompanying drawings, the specific embodiment of the invention is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of motor fan structure of rapid-assembling/disassembling, comprises base plate 1, and the middle part of base plate 1 is provided with mounting hole 11, for the installation of fan; Base plate 1 is provided with the split die casting shaft shoulder 2 matched with motor shaft; The split die casting shaft shoulder 2 is shaping with base plate 1 integrated die-casting, and the split die casting shaft shoulder 2 is positioned on the bore edges of mounting hole 11, can improve the intensity of the split die casting shaft shoulder 2 entirety; Gap is provided with between the die casting shaft shoulder 2; The die casting shaft shoulder 2 is provided with fixed hole 21; The surrounding of base plate 1 is distributed with some fan blades 3; The top of fan blade 3 is connected with connecting plate 4; The edge conjunction of connecting plate 4 has some fixed plates 5; Fixed plate 5 is triangle, and triangular structure is convenient to the wind-guiding effect of high-pressure air; The quantity of fixed plate 5 is identical with the quantity of fan blade 3, and position is corresponding; The top of fan blade 3 is connected with the bottom of fixed plate 5, in fan high-speed rotation, produce high-pressure air; Base plate 1 is provided with some adjusting holes 12, after fan and motor assemble one, adjusts during rotor amount of unbalance use for school.
Gap between the die casting shaft shoulder 2 of the present invention is 2-3mm, is convenient to the installation and removal of fan shaft.
Fixed hole 21 on the die casting shaft shoulder 2 and fan axle journal are locked by bolt by the present invention, by bolt tension stress by fan tightly be locked in rotating shaft; Make to be tightened by bolts the swell increment that amount of deformation is far longer than hot jacket, therefore countershaft is relative with the processing of the mounting hole 11 of fan so not strict, particularly the mounting hole 11 of fan adopts the product of accurate die casting even can process and directly use, which reduce mounting hole 11 machining accuracy of rotating shaft, fan, decrease the energy consumption of heated fan, the time loss to be heated such as to decrease, can provided with fan quickly and easily; When dismounting, more simpler than the fan of hot jacket, only need to unclamp bolt and just easily can take out fan, avoid using drawbench or heating to remove fan, even scrap.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
