As shown in Figure 1 to Figure 2, Fig. 1 is the structural representation according to the special installation tool of one embodiment of the utility model
Figure.Fig. 2 is the structural schematic diagram according to the bushing of the special installation tool of one embodiment of the utility model.It is practical new according to this
A kind of special installation tool of motor radiating fan of type preferred embodiment, motor radiating fan 3 are installed in the non-of motor shaft 4
It drives on end 41, one end of motor radiating fan 3 has fan shoulder 31, and special installation tool includes sleeve body 1 and lining
Set 2.
In some embodiments, sleeve body 1 is closed at one end, and the other end has along its axially extending counterbore 11
Tubular structure；The end of the counterbore 11 of sleeve body 1 has stepped hole 12.The other end of sleeve body 1 has radially
The flange 13 of protrusion.The outer diameter D 4 of flange is substantially not more than the diameter phi 2 of electric fan front end root, that is to say, that works as flange
When pushing the end face of fan shoulder 31, the outer circle of flange 13 cannot encounter the front end root of flabellum, fan of damaging on one side for 13 end faces
Leaf causes fan dynamic balancing bad.In addition, the thickness L2 of flange is generally 10mm or so, too thin intensity is inadequate.
In some embodiments, bushing 2 is embedded in the stepped hole 12 of 11 end of counterbore of sleeve body 1.Stepped hole
Internal diameter D3 and the outer diameter D 3 ' of bushing be gap-matched.The internal diameter D5 of bushing and the outer diameter φ 1 of motor shaft are matched using gap
It closes, the outer diameter φ 1 about 2mm or so of the internal diameter D5 of bushing than motor shaft.The outer diameter D 3 ' of bushing is generally than the internal diameter D5 of bushing
About 5~6mm.The length L3 ' of bushing is substantially not more than the length L3 of stepped hole, and the length L3 ' of bushing is slightly less than stepped hole
Length L3 about 0~0.5mm.The internal diameter D5 that the diameter D1 of counterbore is greater than bushing can be kept away in this way less than the outer diameter D 3 ' of bushing
The inner wall for exempting from the counterbore 11 when assembling fan does not scrape the surface of motor shaft 4 as far as possible, avoids the occurrence of scuffing phenomenon.
In some embodiments, the outer diameter D 2 of sleeve body is generally greater than diameter D1 about 9~15mm of counterbore, in this way
It can guarantee that sleeve body 1 has certain wall thickness, the needs of proof strength.The effective length L1 of counterbore is greater than the non-of motor shaft 4
The distance L4 of end face to the end face of fan shoulder at end is driven, it is electric when design is also not mounted in this way in order to avoid fan
The bottom surface that the anti-drive end 41 of arbor 4 bumps against counterbore 11 causes the anti-drive end 41 of motor shaft 4 to occur scratching phenomenon.
In some embodiments, the material of sleeve body 1 uses metal material, such as with 35#Production or use
The production of Q235 steel plate fission welding form.The material of bushing 2 can use the metal material relatively softer than steel, e.g. silicon
Brass etc. can also use nonmetallic materials, and e.g. vulcanie, nylon material etc. makes, mainly in order that soft material
It is not easy to scratch the surface of motor shaft 4.
In some embodiments, one section of the closing of sleeve body 1 chamfering with 5mm, flange 13 has R2 fillet, convex
The outer wall junction of edge 13 and sleeve body 1 is generally the fillet of R3~5mm, the inside and outside wall of bushing 2 and the inner wall of stepped hole
Finish control in 6.3 microns, the finish of remaining position is generally 12.5 microns.
As shown in figure 3, Fig. 3 is the operation schematic diagram according to the special installation tool of one embodiment of the utility model.?
In the installation process of actual motor radiating fan 3, the mounting hole of motor radiating fan 3 is gently set in motor shaft 4 first
Anti-drive end 41, the end of fan shoulder 31 is then touched with the end face of the flange 13 of the sleeve body of this special installation tool 1
Face, and make the center of bushing 2 and the central alignment of mounting hole as far as possible, the closed end of sleeve body 1 is gently tapped with tool hammer,
It is slowly slided inwards along motor shaft 4 with making 3 uniform force of motor radiating fan, until motor radiating fan 3 is installed in place,
Pay attention to ensuring that the anti-drive end 41 of motor shaft 4 is successfully nested within bushing 2 in the process, motor shaft can be prevented plowing from this way
4 surface.
The various sizes of the special installation tool of the motor radiating fan 3 of the utility model above-mentioned are only schematical,
The utility model is not limited thereto, these sizes can change, the motor of the utility model according to the model of different motors
The special installation tool of radiator fan 3 has plurality of specifications, and various types of motors can be used and use, be common ten below
Kind specification, as shown in the table:
In conclusion the special installation tool of the motor radiating fan of the utility model has the advantage that with a variety of
Model may adapt to the installment work of different sizes, unlike material, different structure fan；Bushing uses soft metal or non-
Metal material can prevent the colliding with and scraping to the motor diameter of axle when installing fan；Structure is simple, easy to operate.Length sleeve
Suitable operator grasps.Meanwhile using the tool can to avoid in fan installation process because tool is not applicable, unbalance stress
The case where damage of fan caused by even or motor other component damage, greatly improves the efficiency of motor solution body running；Reduce wind
Fan the expense of spare parts purchasing and the maintenance cost of motor；Reduce the buying expense of the general utility tools such as copper rod, rubber hammer, wrench set
With；Necessary labor time required for fan is installed is shortened, improves work efficiency, reduces man hour of labour, saved people
Work cost.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
And its practical application, so that those skilled in the art can be realized and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
Formula is limited.
