Position is in most narrow and small place in air-conditioning box, and maintainer can only enter two people reluctantly, and impeller itself is very big very heavy, limited
Small space in, when maintainer taps impeller using the general purpose tool such as copper rod and iron hammer from impeller side, one can only be given
The stress surface of very little for impeller, because impeller is engaged too tight with axle sleeve, impeller can not be separated with axle sleeve, and copper rod
It is a contact surface, so easily making fan blade unilateral stress during percussion, also impeller can may be caused to damage.
Utility model content
The purpose of this utility model is to provide a kind of draught fan impeller tool special for dismounting, and circular axle sleeve is bypassed using one
The sleeve directly contacted with impeller, can thus become a circular stress surface from stress surface, so increase and leaf
The contact area of wheel, makes its uniform force during percussion, and impeller entirety stress, such impeller just can easily take off with axle sleeve
From；Overcome the defect of prior art, solve the above problems.
The utility model provides a kind of draught fan impeller tool special for dismounting, sleeve body and bearing assembly；Sleeve body
One end has removal hole；The diameter of removal hole is more than the diameter of impeller axle bearing sleeve；The depth of removal hole is more than impeller axle bearing sleeve
Thickness；Bearing assembly is arranged in sleeve body, the position of fixes sleeve body.
Further, the utility model provides a kind of draught fan impeller tool special for dismounting, also with following characteristics：Bearing assembly
Including several handles, it is fixed in sleeve body.
Further, the utility model provides a kind of draught fan impeller tool special for dismounting, also with following characteristics：Handle circumference
It is distributed on the circumference of sleeve body.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one
Fig. 1 is the semi-cutaway of blower fan impeller demolition specific purpose tool in embodiment one.
Fig. 2 is the left view of blower fan impeller demolition specific purpose tool in embodiment one.
As depicted in figs. 1 and 2, draught fan impeller tool special for dismounting, including：Sleeve body 100, bearing assembly 200 and bullet
Property pad 500.
One end of sleeve body 100 has removal hole 110.The diameter of removal hole 110 is straight slightly larger than impeller axle bearing sleeve 10
Footpath.The depth L2 of removal hole 110 is more than the thickness L1 of impeller axle bearing sleeve 10.
Bearing assembly 200 includes 2 handles.2 handles 200 are in circumference of the 180 degree circumference uniform distribution in sleeve body 100
On.The handle of bearing assembly 200 holds up sleeve body 100 for user.
Sleeve body 100 has the end face of the side of removal hole 110, sets cushion 500.The thickness of cushion 500 is little
In 2 millimeters.General cushion plays a part of the effect of the cushion in damping, the utility model, is to prevent sleeve sheet
Rigid contact between body 100 and impeller 20, deformation damage is caused during percussion to impeller.
The course of work of draught fan impeller tool special for dismounting：
One staff's both hands holds handle 200, and the removal hole 110 of sleeve body 100 is aligned into impeller 20, leaf is avoided
Wheel shaft bearing sleeve 10；Keep lifting the state of sleeve body 100.Another staff taps the opposite side of sleeve body 100, directly
Depart from impeller axle bearing sleeve 10 to impeller 20, so that impeller 10 be unloaded.Draught fan impeller tool special for dismounting structure in this implementation
Simply, it is easy to carry, but need two staff to carry out execute-in-place.
Embodiment two
Fig. 3 is the semi-cutaway of blower fan impeller demolition specific purpose tool in embodiment two.
Fig. 4 is the left view of blower fan impeller demolition specific purpose tool in embodiment two.
As shown in Figure 3 and Figure 4, draught fan impeller tool special for dismounting, including：Sleeve body 100, bearing assembly 300 and bullet
Property pad 500.Sleeve body 100 and cushion 500 in the present embodiment is identical with the structure of embodiment one, not in repeated description.This
