The opening portion 22 that beam 36 cooperates, during actual assembled, by the effect of crossbeam 36 and opening portion 22, and under fan blade 10
End limited, limited convenient for the lower end to the fan blade 10 and axle sleeve 20 that fit together, can prevent embedded component 30 with
Relative displacement occurs for axle sleeve 20, and convenient for screwing knob 60, and then knob 60 is quickly tightened to the top of embedded component 30.
As shown in Fig. 3,4,5, when actual assembled, axle sleeve 20 is bonded in the mounting hole 11 on fan blade 10 first, then will
Embedded component 30 is assembled on output shaft 41, and the axial limiting of embedded component 30 is realized by the step of the protrusion 413 on output shaft 41,
It is inserted into positioning pin 50, realizes limit completely.Then fan blade 10 is assembled on embedded component 30, lower end passes through 30 lower end of embedded component
36 structure of crossbeam limit, upper end screw knob 60 limit.
Embedded component 30 and 20 mating part of axle sleeve are the cone inclined-plane 321 at both ends, are first conical surface, i.e. circular arc inside axle sleeve 20
The gradient on shape inclined-plane, two inclined-planes is equal.Embedded component 30 and axle sleeve 20 form inclined-plane cooperation, and this cooperation is matched relative to existing
Conjunction is compared, and is guaranteed that fit-up gap is smaller and reduces the cooperation of axis hole 21 and is assembled eccentric situation, reduces unbalance mass, effectively
Reduce the amplitude of handpiece vibration.
Intermediate part diagonal bar 34 does not connect with first conical surface on the inner wall of axle sleeve 20 between two cooperation cone inclined-planes 321
Touching primarily serves the effect of assembly guiding, in place and prevents the first taper-face contact too big convenient for user assembled, caused stuck
The problem of.And this structure, the lower end of axis hole 21 are provided with reamer 211, are convenient in assembling process user assembled.Embedded component
The crossbeam 36 of 30 lower ends, can play the role of limit, so that being not in pressure between contact surface when user installation fan blade 10
It is excessive, it is difficult to the problem of dismantling.
As it can be seen that the present invention is straight instead of original axle sleeve and output shaft by way of first conical surface and the second cone match
The form of face cooperation can effectively avoid assembling not positive problem, and the increase of unbalance mass, leads to asking for head shake
Topic.In addition, solve the problems, such as that inclined-plane is processed directly on output shaft to be difficult to by way of increasing embedded component, and
It can prevent output shaft surface oxidisation.And first conical surface and the second taper-face contact are relative to contact is faced directly, and user installation is more
It is easy.Embedded component and output shaft use part interference fit, ensure that the assembly gapless of embedded component and output shaft.Embedded component
When cooperating with fan blade axle sleeve, using the contact on part inclined-plane, contact area reduces, so that being not easy in disassembly process stuck.
Structure and existing structure are verified on identical model machine after improvement, and there is 120RPM in existing structure vibration section, are improved
There is 80RPM in structural vibration section, and effect is obvious, as shown in table 1.
Table 1:
According to another aspect of the present invention, a kind of electric fan, including nose assembly are provided, nose assembly is above-mentioned implementation
Electric fan head component in example.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
The present invention, which is faced directly by way of first conical surface and the second cone match instead of original axle sleeve and output shaft, to be matched
The problem of form of conjunction, can effectively avoid assembling not positive problem, the increase of unbalance mass, and head is caused to be shaken.Separately
Outside, by way of increasing embedded component, solve the problems, such as that inclined-plane is processed directly on output shaft to be difficult to, and can be to prevent
Only output shaft surface oxidisation.And first conical surface and the second taper-face contact are more easier relative to contact, user installation is faced directly.It is interior
Inserts and output shaft use part interference fit, ensure that the assembly gapless of embedded component and output shaft.Embedded component and fan blade
When axle sleeve cooperates, using the contact on part inclined-plane, contact area reduces, so that being not easy in disassembly process stuck.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
