Various combinations.For example, according to the arrangement form of the Anti-inclining block 13 on stator 12, corresponding position setting on rotor 11 with
The Anti-inclining block 13 matched.For example, Anti-inclining block 13 is arranged in the front side edge edge on stator 12 in overlapping region 14
When, Anti-inclining block 13 can be set in the back side edge edge of overlapping region 14 on rotor 11, or opposite.In another example stator 12
On only when Anti-inclining block 13 is arranged in one of the front side edge edge of overlapping region 14 and back side edge edge, can on rotor 11
It is respectively provided with Anti-inclining block 13 in the front side edge edge of overlapping region 14 and back side edge edge, or opposite.In another example stator 12
Arrangement can be interted with the Anti-inclining block 13 for being located at the same side on rotor 11, for later lateral edge portion, the anti-dumping on rotor 11
Anti-inclining block 13 on oblique block 13 and stator 12 can be circumferentially alternately arranged.
Obviously, including rotor 11, stator 12 can also use arrangement above-mentioned when outer.
It prevents rotor 11 and stator 12 from contacting, the winding of the two is mainly prevented to be in contact.For this purpose, when being set on stator 12
When setting Anti-inclining block 13, Anti-inclining block 13 can be set in the stator core of stator 12.When anti-dumping is arranged on rotor 11
When oblique block 13, Anti-inclining block 13 can be set in the rotor rim of rotor 11.
The shape of Anti-inclining block 13 be not limited to it is shown in FIG. 1 towards radial outside extend shape, relative stator 12 or
Rotor 11 is prominent.Hereinafter, illustrating several variations of Anti-inclining block 13 in conjunction with Fig. 3 A to Fig. 3 D.
As shown in Figure 3A, the Anti-inclining block 131 of crotch form can be set on stator 12.
As shown in Figure 3B, can 12 on stator on the block being laterally extended is set, setting tilts down and prolongs on rotor 11
The block stretched, to constitute Anti-inclining block 132.

As shown in Figure 3D, Anti-inclining block 134 can be for from stator 12 towards the convex block outstanding of rotor 11.
The shape and construction of Anti-inclining block 13 are not limited to aforementioned forms.Moreover, the specific size of Anti-inclining block 13 can
According to physical fault situation and simulation scenarios, determined.In brief, Anti-inclining block 13 should be located at rotor 11 and occur partially
When turning on mobile path, 11 further occurrence of rotor can be stopped to tilt.Under the premise of herein, shape, construction and size etc.
It can carry out various selections.
Anti-inclining block 13 preferably uses wear-resistant vibration-damping material, such as rubber.
Anti-inclining block 13 can be integrally formed with rotor 11 or stator 12, separately fabricated can also be installed to later rotor
11 or stator 12.
The shaft 3 of the embodiment of the present invention can be connected to dead axle 4 by sliding bearing.Sliding bearing be mainly used in high speed,
Precision machinery and the biggish machinery of low-speed heave-load, shock loading.The technical characterstic of sliding bearing is highly suitable to be applied for wind-force hair
The base bearing of motor group.Also, it is long to design good sliding bearing life, can break through common rolling bearing to wind power generating set
The limitation in service life.However, when using sliding bearing in the past, the meeting Shortcomings in terms of air gap control, the reason is as follows that：
(1) sliding bearing inherently needs gap and oil film, therefore the variation of oil film thickness can also draw in operational process
Play the variation of air gap.
(2) there are radial internal clearances and end-play for sliding bearing, under different load, since there are radial internal clearances and axis
To clearance, the deflection of shaft 3 will cause, as shown in Figure 2.The deflection of shaft 3 can greatly cause the variation of air gap, or even cause
The danger that rotor 11 and stator 12 contact.
But according to an embodiment of the invention, when shaft 3 is due to sliding bearing clearance run-off the straight, Anti-inclining block
13 can prevent the over-tilting of rotor 11, keep the air gap of generator in a certain range.Therefore, sliding axle can be utilized
The advantages of holding, and the adverse effect that sliding bearing generates power generator air gap can be eliminated.
Preferably, sliding bearing may include upwind thrust bearing shoe 51, lower wind direction thrust bearing shoe 52 and radial bearing shell 53.On
Wind direction thrust bearing shoe 51, lower wind direction thrust bearing shoe 52 and radial bearing shell 53 are mountable on the mounting surface of shaft 3 or dead axle 4.On
As long as wind direction thrust bearing shoe 51, lower wind direction thrust bearing shoe 52 and radial bearing shell 53 are capable of forming two work for bearing axial load
Face and a working face for bearing radial load.Circumferentially spaced it can arrange multiple upwind thrust bearing shoes 51, lower wind direction
Thrust bearing shoe 52 and radial bearing shell 53.Preferably, every piece of bearing shell is all corresponding with a retainer, which is bolted
In shaft 3 or dead axle 4, bearing shell is mounted on corresponding retainer.
It, can be and for the size of control clearance as shown in figure 4, in order to reduce the influence of sliding bearing clearance
Adjusting gasket is respectively arranged between upwind thrust bearing shoe 51, lower wind direction thrust bearing shoe 52 and radial bearing shell 53 and mounting surface
54.Adjusting gasket 54 can control the size of clearance.Adjusting gasket 54 has different grade and thickness, can control clearance
Range and precision.The rigidity of adjusting gasket 54 is very big, in the case where being subject to external force, is unlikely to deform, and is still able to maintain original thickness
Degree and precision.
Adjusting gasket 54 can be connected to shaft 3 or dead axle 4 by aforementioned retainer.
Above, it is illustrated by taking the integrally formed structure of shaft 3 and rotor 11 as an example.But not limited to this, 3 He of shaft
Rotor 11 is fixedly mounted after can also manufacturing respectively.Moreover, as shown in figure 5, can be used to eliminate the transmission effects of clearance
The rotor 11 of flexible connecting member 6 connection shaft 3 and generator.The rigidity of flexible connecting member 6 is less than shaft 3 and rotor 11
Rigidity, i.e., so-called flexibility are that in contrast, flexible connecting member 6 is still rigid member, and only its rigidity is more slightly smaller than surrounding rigidity,
Thus the vibration that can reduce influence and the shaft rotation of sliding bearing clearance influences.The variation of sliding bearing clearance is to pass through shaft
3 are transmitted to the rotor 11 of generator, to influence power generator air gap.Therefore, by assigning certain flexibility to the transmission path,
The transmitting that can reduce load reduces the influence of clearance.Meanwhile load can also weaken the variation of sliding bearing clearance.
As shown in figure 5, flexible connecting member 6 can be used section and be the annular component of T-type, and pass through for the ease of installation
Bolt is mounted between shaft 3 and rotor 11.But its specific structure is without being limited thereto.
The front end of rotor 11 can be connected to shaft 3 by flexible connecting member 6, and rear end can pass through rolling bearing or sliding axle
It holds and is connected to dead axle 4, to further decrease the influence of clearance.
Shaft may be integrally formed with wheel hub, i.e., shaft combines together with wheel hub, and blade is mounted directly in shaft.Alternatively,
Shaft and wheel hub are rigidly connected after can independently manufacturing.
Dead axle 4 can be fixed to engine room foundation, to transfer loads to tower.Stator 12 is fixed with respect to dead axle 4, can directly connect
It connects on dead axle 4.Stator 12 and the connection structure of dead axle 4 are omitted in attached drawing.
For shaft 3 and the relativeness of dead axle 4, shaft 3 can extend into the inside of dead axle 4, so as to from dead axle 4
Inside touch the sliding bearing as base bearing, realize and replaced on the tower of bearing, maintenance cost saving.
According to an embodiment of the invention, Anti-inclining block can prevent the over-tilting of rotor when rotor run-off the straight,
It prevents the air gap between rotor and stator to be less than predetermined value, and then prevents rotor and stator contact from burning.Especially for application
Blower of the sliding bearing as main shaft bearing, can be effectively prevented generator amature and stator contact is burnt.Further, pass through
Installation and adjustment gasket can control the size of clearance, reduce sliding bearing clearance to the adverse effect of air gap.Further, lead to
It crosses and flexible connecting member is set between shaft and generator amature, can reduce sliding bearing clearance to the unfavorable shadow of air gap
It rings.
