Description
Technical field
The present invention relates to the rotor casing in rotor dynamics touches technical field of rubbing, more particularly to a kind of rotor casing is separated
Device.
Background technology
The distance between tumbler and quiet part in rotating machinery, that is, the rotating-static clearance that we generally say is to whirler
The efficiency of tool has important impact.In the fuel consumption of aircraft, waste because ring wear gap increases leakage
Fuel accounts for the 1% of total amount.It is appropriate to reduce rotating-static clearance, the Internal flow loss that electromotor air leakage causes can be reduced, also allow for
The efficiency of electromotor is improved.Typically take different seal means to realize this target at present, such as brush seal and honeycomb is close
Envelope etc..Data shows that these seal forms can reduce rate of fuel consumption 1%-2%.However, with the continuous reduction of rotating-static clearance,
The chance for colliding between tumbler and quiet part and rubbing also is greatly increased.Under actual working state, due to inevitable
Rotor machining it is uneven, situations such as be heated uneven, in fact it could happen that the relative displacement of rotor and stator exceedes between the two
Gap is installed, can be come in contact, collide and be rubbed between rotor and stator, here it is our usually said rotor-stator rubbings show
As.In general, rotor misalignment, imbalance, generation；The common situations such as crackle, uneven temperature field and flow induced vibrations effect
Rotor excessive vibration may be all caused to rub so as to cause to touch.
Used as a kind of most common failure of rotating machinery, serious rotor-stator rubbing has very big hazardness.Touch when rubbing,
Turn Jing Jiechuweizhichu often produce it is substantial amounts of heat cause rotor deformation is worse off, its result be probably system vibration increase,
Touch the intensity raising that rubs.The serious possible initiation multiple failure that rubs that touches intercouples, and the safety generation to system has a strong impact on, such as
The catastrophic effects such as leaf destruction, rotor unstability, engine fires.Harrier the second frame prototype P1127 takes a flight test within 1962
When, flying horse engine compressor rotor blade causes titanium to catch fire with the mutual friction of casing phase, air crash.On the other hand, it is nearest
Research shows that the different types of consequence for touching the generation that rubs has larger difference.The experiment of Padova etc. gives different leaves-casing
Blade casing under the conditions of intrusion volume is touched and rubbed, and its conclusion shows that in check touching is rubbed and may not produce destructiveness to rotor-support-foundation system
Affect.And in the research of Black and Yu etc., a kind of self-excitation for being referred to as repercussion whirling motion is touched to rub and had made intensive studies.He
Conclusion show that this repercussion whirling motion belongs to a kind of strong self-excited vibration, once and rotor-support-foundation system enter this kind of self-excited vibration
To there is lasting touching for larger intrusion volume with casing and rub in state, rotor, only by reduce rotating speed also can not cause rotor with
Casing departs from.For vane rotor system, there is this kind of touching and rub and will produce destructive effects to system.Therefore, prior art
Also without it is a kind of can quickly, steady, completely rotor casing segregation apparatuss to be avoiding touching the destructive effects to system of rubbing.

One has contact with 211 and second has contact with 212 for L-type structure, and first has contact with 211 vertical edges connects first pair of extension set casket 101, and second takes
The vertical edges of hook 212 are located in the lower half of the groove of vertical guide rail 210 of the second locating support, and it is spacing by vertical guide rail 210,
Can only move in the vertical direction.First has contact with the second hook-like configuration 216 for having contact with horizontal sides with second mutually fastens, and second has contact with
212 vertical edges tops are stuck in the hook and slot of the first hook-like configuration 208 of horizontal sliding bar one end of the second locating support, by first pair
Extension set casket 101 and second pair of sealing docking of extension set casket 102.
Second the second hook-like configuration 216 for having contact with horizontal sides connects second hook by a connecting spring 213 being disposed vertically
Ground is fixed in lever 214 immediately below type structure, one end of lever 214 by articulated elements 215.
When rotor casing normal work, first has contact with the second hook-like configuration 216 mutually button for having contact with horizontal sides with second
Close, second have contact with 212 vertical edges tops be stuck in the second locating support horizontal sliding bar one end the first hook-like configuration 208 hook and slot
It is interior, first pair of extension set casket 101 and the sealing docking of the second pair of extension set casket 102.When rotor casing is touched to rub, to lever 214
The other end applies a downward power, and lever 214 has contact with the second hook-like configuration 216 of horizontal sides by connecting spring 213 pair second
Apply a downward pulling force, in the presence of the pulling force, second has contact with 212 along the slide downward of vertical guide rail 210, and second has contact with
212 vertical edges tops skid off from the hook and slot of first hook-like configuration 208 of horizontal sliding bar one end of the second locating support, while the
One has contact with the second hook-like configuration 216 for having contact with mutual fastening with second breaks off relations, and first pair of extension set casket 101 is in the first locating support
Recall backward in the horizontal direction under the pulling force effect of spring 209, second pair of extension set casket 102 draws in the spring 209 of the second locating support
Recall backward in the horizontal direction under power effect so that first pair of extension set casket 101 and second pair of extension set casket 102 are separated, and to dividing
Casing is separated with rotor 103, it is achieved thereby that rotor 103 and casing it is quick, steady, be totally separated from, effectively prevent strong
The strong destruction for touching the effect of rubbing to rotor-support-foundation system.
