Fig. 2A and 2B shows the supporting system 10 being mounted in motor 2, which is integrated into supercharging device 1
In.But supporting system 10 or motor 2 can also be used in other devices different from supercharging device.It can see herein, diameter
To bearing 200 radially 24 stator 100 is formed between 2 rotor 400 of motor that is loaded into stator 100.That is, bearing system
System 10 further includes axis 500 together with the rotor 400 being mounted on an axle.Rotor 400 and axis 500 system in the example shown in attached drawing
At, but can also be made separated from each other in the alternative design.Rotor 400 is a part of axis 500 herein, on axial 22
It is predominantly located in stator 100.This external enwergy sees that transverse bearing 200 is not arranged in stator 100 on axial 22 herein
Right side or left side.In other words, transverse bearing 200 does not protrude past the length of stator 100 on axial 22.That is, radial axle
200 are held to be arranged in stator 100 on axial 22.It is possible thereby to save structure space and weight.Finally, this may cause structure
More compact device.
Similar to the transverse bearing 2000 of the known supporting system 1010 of Fig. 1, supporting system according to the present utility model
10 transverse bearing 200 includes at least one undulating membrane 210 and at least one smooth film 220 (see Fig. 2A and 2B).Therefore, radial
Bearing 200 can also be referred to as foil bearing or (as described above) air bearing.Undulating membrane 210 and smooth film 220 can also be total
Body is referred to as bearing film 210,220.Undulating membrane 210 and smooth film 220 (are especially shown in along the arrangement of inner peripheral surface 170 of stator 100
Fig. 3 B).In other words, undulating membrane 210 and smooth film 220 are placed in the clamshell of stator 100 in inner peripheral surface 170 radially
On inner surface 150.Here, smooth film 220 inwardly (is especially shown in figure close to the undulating membrane arrangement that reclines of undulating membrane 210 on radial 24
3C).Smooth film 220 is arranged close to rotor 400 or axis 500 outward on radial 24.In addition, undulating membrane 210 is tightened radial 24
It adjacent stator 100 and radially 24 arranges with reclining stator.Undulating membrane 210 is designed radially herein 24 by 220 bias of smooth film
To 2 rotor 400 of motor being mounted in stator 100.It, can be in quilt in the work of supporting system 10 by this expedients
Very narrow air gap is generated between 2 rotor 400 of motor being fitted into stator 100 and smooth film 220, it is possible thereby in rotor
Supporting role is generated between 400 and stator 100 or between rotor 400 and smooth film 220.Therefore, rotor 400, smooth film
220, undulating membrane 210 and stator 100 are directly abreast adjacently positioned on radial 24 respectively.Rotor 400, smooth film 220, wave
Therefore transverse bearing 200 (especially seeing Fig. 2A, 2B and 3D) is collectively formed in shape film 210 and stator 100.Undulating membrane 210 is designed to lead to
Radial 24 movement for crossing smooth film 220 can be elastically compressed between smooth film 220 and stator 100, thus at work can be
Narrow air gap is formed on radial 24 between the rotor 400 being mounted in stator 100 and smooth film 220.
Therefore, rotor 400 or axis 500 form the first bearing surface of transverse bearing 200, on the direction of smooth film 220
Orientation, and smooth film 220 forms the second bearing surface of transverse bearing 200, is upwardly oriented in the side of rotor 400.Work as bearing
When system 10 or motor 2 or supercharging device 1 do not work, i.e., when rotor 400 or axis 500 do not rotate, smooth film 220, which reclines, to be turned
Sub 400 (such as seeing Fig. 2A and 2B).In other words, the first bearing surface of transverse bearing 200 reclines second of transverse bearing 200
Bearing surface.When motor 2 or supercharging device 1 are transferred to working condition, rotor 400 or axis 500 itself are rotated and in 400 He of rotor
Occurs circumferentially 26 relative motion between smooth film 220.As a result, air radially smooth film 220 and rotor 400 it
Between flow through and apply radial force to rotor 400 and smooth film 220.Thus there is air gap between rotor 400 and smooth film 220,
Thus to obtain supporting role.The air gap is shown schematically in fig. 3d.That is, in the first bearing surface and diameter of transverse bearing 200
To radially 24 there is air gap between the second bearing surface of bearing 200.By the compressibility of undulating membrane 210, smooth film 220 can
It moves and would be pressed against on stator 100 relative to undulating membrane 210 with radially 24.Therefore stator 100 is especially used as fixing axle
It holds.Therefore, undulating membrane 210 (elasticity) is compressed between smooth film 220 and stator 100.Especially therefore reason, undulating membrane 210
Elastic component 210 or elastic membrane 210 can also be referred to as, and smooth film 220 also referred to as supports facial mask 220.In other words, this
Meaning the smooth film 220 can directly recline rotor 400 when supporting system 10 or motor 2 or supercharging device 1 do not work
It arranges (such as seeing Fig. 2A and 2B).That is, at work, by smooth film 220 radially 24 relative to undulating membrane 210 until
The radially movement of 24 stators 100 of adjacent undulating membranes 210 outward, can be radially 24 between smooth film 220 and rotor 400
Form air gap.The air gap generates supporting role and smooth film 220 compared to the rotor 400 that reclines or rolling bearing lead to very little
Friction.
Herein it should be noted that schematically showing for the supporting system 10 of the utility model is only presented in attached drawing.Such as transverse bearing
The waveform trend of 200 undulating membrane 210 is preferably designed to circumferentially 26 in fig. 2, rather than as shown in figure along axial 22.
Fig. 3 A to 3D shows the variant installation condition of the supporting system 10 of the utility model.In all four width views
It can be clearly seen, stator 100 is designed to can be fixed bearing film 210,220 on or in stator.Fig. 3 A is shown
Stator 100 with multiple winding ribs 110, in figure 3b, multiple windings 140 are wound around winding rib.Also in Fig. 3 B
See that filler 130, filler are arranged between winding rib 110 on circumferential 26 and are respectively formed filler rib 132 there.Such as
Shown in Fig. 2A and 2B, filler can also surround winding rib 110 on axial 22.That is, 142 He of first axis end of stator 100
Second axial end 144 of stator 100 can be made of filler 130.Fig. 3 C is also shown other than the stator 100 of Fig. 3 C to be loaded into
Bearing film 210,220 in stator 100.Here, supporting system 10 is for example comprising each three undulating membranes 210 and three smooth films
220.In other embodiments, undulating membrane 210 and the quantity of smooth film 220 can also be with more than three or less than three.Wave
The quantity of shape film 210 and the quantity of smooth film 220 are also possible to different from each other.Undulating membrane 210 and smooth film 220 are set at this time
