In the rotating machineries such as aeroengine, use rolling bearing as supporting, because the damping that self can provide is very little, be unfavorable for vibration damping.For ensureing the safe and stable operation of the rotary machine rotor systems such as aeroengine, widely use squeeze film damping SFD (Squeeze Film Damper) bearing technology vibration damping at present.Because the dynamic property of SFD can not carry out ACTIVE CONTROL, and under design or mis-machined situation, there will be the nonlinearity of oil film rigidity, cause bistable state, locked and non-coordinating precession phenomenon, cause vibration of rotor system excessive even touch rub, tired, limit the Applicable scope of SFD.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Summary of the invention:
The invention provides a kind of novel mixed damper, carry out the vibration control of the rotary machine rotor systems such as aeroengine, this kind of type hybrid damper can make up the deficiency of squeeze film damper, improves the reliability of the vibration control of the rotary machine rotors such as aeroengine.
The present invention adopts following technological scheme: a kind of type hybrid damper, it includes support, rotor, support the rolling bearing of described rotor and support the rotor cage type elastic support of described rolling bearing, wherein rotor cage type elastic support adopts returning type structure, and be directly fixed on support, type hybrid damper also includes and is arranged in rotor cage type elastic support, metal-rubber ring between outer shroud, and the electromagnetic damper be arranged between described rotor cage type elastic support and support, described electromagnetic damper includes electromagnetic damper silicon steel plate stator, be around in the electromagnetic damper coil on electromagnetic damper silicon steel plate stator, electromagnetic damper silicon steel plate group, described electromagnetic damper silicon steel plate group is set on described rotor cage type elastic support, and the side of described electromagnetic damper silicon steel plate group is fixed by the copper ring with rotor cage type elastic support interference fit.
Described type hybrid damper also includes sensor stand and described sensor stand is fixed on the sensor gland on the left of described electromagnetic damper, and described electromagnetic damper is fixed between described support and sensor stand.
Described electromagnetic damper adopts 8 pole formulas, and 8 magnetic poles are arranged along described periphery of rotor.
Uniformly along horizontal and vertical direction on described sensor stand be provided with 4 in order to detect the rotor cage type elastic support that causes due to the vibration of the rotor radial displacement transducer along the change of horizontal and vertical direction vibration displacement.
Described rolling bearing is supported on described rotor cage type elastic support.
The arranged outside of described rolling bearing has bearing (ball) cover, is provided with the pad of the axial internal clearance for adjusting described rolling bearing between described bearing (ball) cover and sensor gland.
Described rotor is located by rolling bearing inner ring.
The present invention has following beneficial effect:
(1). overcome that rigidity when being used alone rolling bearing is large, damping is little, rotor is difficult to cross over critical speed of rotation and vibrate violent shortcoming;
(2). avoid there is oil degradation, the shortcoming that working state is relevant with temperature and frequency when using squeeze film damper;
(3). make up rigidity, underdamping when electromagnetic damper acts directly on rotor-support-foundation system, the problems such as uncontrollable large impact shock;
(4). provide main damping by metal-rubber ring, electromagnetic damper only needs to provide adjustable damping, is conducive to the overall dimensions reducing damper, is applicable to the needs of lightweight, high speed rotor;
(5). can work under particular job environment such as high temperature, high pressure, high vacuum, ultralow temperature or condition.
