Abstract
The utility model discloses a kind of motor fan structure of rapid-assembling/disassembling, comprise base plate, the middle part of described base plate is provided with mounting hole, and described base plate is provided with the split die casting shaft shoulder matched with motor shaft; The described split die casting shaft shoulder is positioned on the bore edges of mounting hole; Gap is provided with between the described die casting shaft shoulder; The described die casting shaft shoulder is provided with fixed hole; The surrounding of described base plate is distributed with some fan blades; The top of described fan blade is connected with connecting plate.The utility model structure is simple, changes and easy to maintenance, and operational reliability, part processing precision is high.
Description
Technical field
The utility model relates to machine field, refers 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.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and provides a kind of structure simple, and repair and replacement are convenient, the motor fan structure of practical rapid-assembling/disassembling.
The utility model 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.
Gap between the described die casting shaft shoulder 2 is 2-3mm.
Described base plate 1 is provided with some adjusting holes 12.
The beneficial effects of the utility model are: 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. 1 the utility model structural front view;
Fig. 2 the utility model structure worm's eye view.
Embodiment
Now by reference to the accompanying drawings, the utility model embodiment 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, and 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; 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, in fan high-speed rotation, produce high-pressure air.
Gap between the utility model die casting shaft shoulder 2 is 2-3mm, is convenient to the installation and removal of fan shaft.
The utility model 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.
Fixed hole 21 on the die casting shaft shoulder 2 and fan axle journal are locked by bolt by the utility model, 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 embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification 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 utility model.
