Embodiment 1,
Fig. 4 is this example structure schematic representation, and it is to adopt example of the present invention in small-sized or table top centrifuge.As seen from the figure, the flexible shaft 2 of high speed rotating is rotating shaft unique in this structure, and its top is equipped with the rotary head or the rotary drum 1 that are used to hold separated object, and this rotation system adopts motor direct-drive.Between rotary head or rotary drum 1 bottom and motor, be provided with black box 8,, prevent that extraneous harmful gas and liquid from entering motor cavity to realize motive sealing.Motor is energy-efficient asynchronous motor, and its rotor 3 is cup type rotors, and this rotor is fixed on the Flexible Rotating 2.Upper bearing (metal) 5 is positioned on the cylindrical sleeve above the motor lower end cap, and in the inner chamber of the rotor cup 3 of motor supporting shaft 2.Lower bearing 7 is contained in rotating shaft 2 bottom, and be fixed in the damper 10 interior covers, should interiorly overlap the double greaser of making lower bearing 7, damper 10 is made of interior cover, overcoat and elastic supporting element 6, inside and outside cover is hollow cylindrical shell, between cover and the overcoat plurality of elastic supporting element 6 is housed in the damper 10, when stressed, produces elastic displacement in both having allowed between the overcoat, guarantee that again they can recover concentric position.In above-mentioned damper 10, between cover and the overcoat viscous damping fluid is housed also, makes the squeeze film that forms one deck annular, so that the vibration of damping rotor-support-foundation system and precession.Damper 10 overcoats are fixed on the lower end surface of motor lower cover, and in the present embodiment, upper and lower bearing 5 and 7 all adopts the spiral grooved bearing of full-film lubrication.Experimental result proves, under operating conditions, She Ji high speed rotating system like this, the high pressure oil film that whole rotor-support-foundation system can be produced by spiral grooved bearing fully floats, thereby avoided direct contact between bearing and the axle, improved the stability and the reliability of whole rotation system.The novel high speed rotation system that present embodiment provides has advantages such as running is reliable and stable, power consumption is low, the life-span long, simple in structure, easily manufactured and with low cost.
Fig. 5 is that the present invention is applied to compact centrifuge or is applied to adopt the embodiment of the centrifugal spindle of wet spinning technology.Owing to want continuous drain in the solid-liquid separation process, these liquid properly must be collected, especially adopt the centrifugal spindle of acid wet spinning technology, discharge very strong acid solution and the gas of corrosivity in the spinning process continuously, for preventing to corrode motor component and befouling environment, must increase the distance between centrifugal reel and the rotor so that the motive sealing of structure more complicated is set, thereby increase bearing greatly--the design difficulty of rotor dynamics.The present invention has solved this problem well.The present embodiment upper bearing (metal) adopts rolling bearing, and lower bearing adopts spiral grooved bearing, and other structure characteristic is with embodiment 1.Experiment showed, that present embodiment has good run stability and reliability, and have remarkable energy saving effect.
As shown in Figure 6, this embodiment is the application of the present invention on disk centrifugal separator.According to varying in size of installed power, present embodiment both can adopt independent motor driven (adopting cup type motor rotor 3), also can adopt belt drives (adopting cup type belt pulley 30).Upper bearing (metal) 5 can adopt rolling bearing, also can adopt spiral grooved bearing, and 7 of lower bearings are preferentially selected spiral grooved bearing for use, and makes the float element of it and damper 10 be bonded into an integral body.Adopt the large-scale disk centrifugal separator of present embodiment, the same with compact centrifuge, can obtain the reliable and stable effect that turns round equally.
Fig. 7, Fig. 8 are that the present invention is applied to the directly embodiment of the ring ingot formula spindle of driving of independent motor.Fig. 7 scheme metal (upper adopts spiral grooved bearing entirely, and they can make axle float fully.In Fig. 8 scheme then metal (upper adopt conventional spindle bearing entirely--be the roller bearing that upper bearing (metal) adopts no inner ring, lower bearing adopts top formula sliding bearing.In these two kinds of schemes, all adopted the damper of particular design of the present invention.Can adjust quality and the elasticity and the damping parameter of damper easily by physical dimension and material composition that changes elastic element 6 and the further feature size that changes damper, thereby its performance is optimized.Adopt the ring frame spinning spindle of present embodiment under per minute 10000-40000 commentaries on classics condition, long-term stability to turn round reliably, vibrate very little.
Fig. 9, Figure 10 are the embodiments that the present invention is applied to bel-drivenn ring ingot formula spindle.Fig. 9 scheme metal (upper adopts spiral grooved bearing entirely.Figure 10 scheme then adopts conventional spindle bearing--and be that upper bearing (metal) adopts inner ringless roller bearing, lower bearing adopts top formula sliding bearing.Two kinds of schemes have all adopted the damper of particular design of the present invention, thereby have the premium properties identical with embodiment 4.Such spinning spindle can long-term stability turn round under per minute 10000-40000 commentaries on classics condition reliably.
