The position that the end of axle journal 11 is corresponded on 12 has a shaft shoulder；First oilhole 111A, the axle journal are set in the axle journal 11
The first oil groove 112A is offered on 11 male cone (strobilus masculinus)s 113, the first oilhole 111A connects with the first oil groove 112A；Height adjusting block 3,
It is set on the axle journal 11 and its one end offsets with the shaft shoulder on the end axle body 12 of axle journal 11；Bearing assembly 2, has
With the inner conical surface 213 of 113 identical taper of male cone (strobilus masculinus) on the axle journal 11；The bearing assembly 2 and the cone match of axle journal 11,
The other end of the end of the bearing assembly 2 and the height adjusting block 3 offsets so that the bearing assembly 2 and the axle journal 11
Between form interference connection, by adjusting the thickness of the height adjusting block 3, can control the bearing assembly 2 and the axle journal
The magnitude of interference coordinated between 11.
As shown in Fig. 2 to reach preferably dismounting effect, according to the length of axle journal 11, the oil on the male cone (strobilus masculinus) 113 of axle journal 11
Oilhole in groove and axle journal 11 can each open up it is multiple, for example, in the present embodiment, except the first oil groove 112A, the first oil
Outside the 111A of hole, the 3rd oilhole 111B, the 4th oilhole are additionally provided with（Not shown in figure）, and with the 3rd oilhole 111B, the 4th oil
3rd oil groove 112B, the 4th oil groove 112C corresponding to hole.
As shown in Fig. 3 ~ 5, in the present embodiment, the bearing assembly includes：Axle sleeve 21, it has outer ring and inner ring, and this is interior
Circle forms described inner conical surface 213；Bearing 22, it is set on the outer ring of the axle sleeve 21, the quantity of bearing 22 is set as needed
It is fixed.Bearing (ball) cover 23, it is arranged on one end away from axle body 12 on axle sleeve 21.
The second oilhole 211A is provided with described axle sleeve 21, the second oil groove 211B is offered on the outer ring of axle sleeve 21, should
Second oilhole 211A connects with the second oil groove 211B.As shown in figure 4, in the present embodiment, to reach preferably dismounting effect, axle sleeve
The 5th oilhole 211B, the 6th oilhole are additionally provided with 21（Not shown in figure）, and it is corresponding with the 5th oilhole 211B, the 6th oilhole

Preferably, circumferences of the first described oil groove 112A along the male cone (strobilus masculinus) of axle journal 11 opens up.The second described oil groove
Circumferences of the 211B along the outer ring of axle sleeve 21 opens up.
The assembly and disassembly principle of the utility model middle (center) bearing is as follows：Preferably, bearing 22 is heated using sensing heater, then will
Bearing 22 is filled on axle sleeve 21, tightens bearing (ball) cover 23, completes the assembling of bearing assembly 2.When dismantling bearing assembly 2, first by axle
Socket end lid 23 is removed, then by oilhole toward squeezing into hydraulic oil in axle sleeve 21, when forming oil film between bearing 22 and axle sleeve 21,
Bearing 22 is removed rapidly, as shown in figure 5, because bearing assembly 2 is in assembling process, bearing 22 and axle sleeve 21 will not be relative
Slide, axle sleeve 21 is not damaged, and is repeated and is utilized.
As shown in fig. 6, the dismounting principle of bearing assembly 2 is to remove the bearing (ball) cover 23 outside bearing 22, by oilhole toward top
Spiral shell rotor 1 squeezes into hydraulic oil, and pressure P1, when hydraulic oil enters 21 inner conical surface 213 of axle journal 11 and axle sleeve, hydraulic oil will force axle
The distending of 21 inner conical surface 213 is covered, meanwhile, component of the oil pressure in axial direction will release bearing assembly 2, in order to prevent that bearing assembly 2 is prominent
So ejection need to add nut 4 according into accident in shaft end.
As shown in fig. 7, the process of installation is, after bearing assembly 2 takes out first, height adjusting block 3 is taken out, is then loaded new
Height adjusting block 3 and the bearing assembly 2 that matches therewith, paste the inner conical surface 213 of axle sleeve 21 and the male cone (strobilus masculinus) 113 of gyrorotor 1
Tightly.By the oilhole of gyrorotor 1, toward oil groove in squeeze into hydraulic oil, pressure P1（The inner conical surface 213 of axle sleeve 21 is by hydraulic oil
Effect distending, the male cone (strobilus masculinus) 113 of gyrorotor 1 are reduced by the effect of hydraulic oil, and oil film will be formed between interior male cone (strobilus masculinus), coordinate cone
Coefficient of friction substantially reduces between face）, it is preferred that squeeze into hydraulic oil, pressure P2 toward hydraulic nut 5.Now, in hydraulic nut
In the presence of 5, bearing assembly 2 will move relative to gyrorotor 1.Then P1 pressure, P2 pressure are improved, bearing assembly 2 will be relative
Gyrorotor 1 continues to move to.So repeatedly, until axle sleeve 21 is adjacent to height adjusting block 3.Finally, oil pressure P1 is shed, unloads deoil again
P2 is pressed, tightens the race bearing end cap 23 of bearing 21.
Although content of the present utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as to limitation of the present utility model.After those skilled in the art have read the above, for
A variety of modifications and substitutions of the present utility model all will be apparent.Therefore, the scope of protection of the utility model should be by appended
