Abstract
Electrical spindle for centrifugal spinning is a kind of centrifugal spindle that is directly driven by single-motor, and it is to use in textile industry, especially one of key equipment in the viscose long fiber spinning process.The characteristics of novel centrifugal spinning electric ingot are to utilize single axle to substitute the hollow shaft one solid shafting twin shaft cone match location and the torsion pass structure of former electrical spindle for centrifugal spinning; Upper bearing (metal) is hidden among the cup type rotor of motor; Lower bearing can adopt common rolling bearing, also can adopt the helicla flute sliding bearing of full-film lubrication; Drive motors both can adopt energy-efficient asynchronous machine, also can adopt the novel synchronous motor.
Description
The present invention relates to a kind of electrical spindle for centrifugal spinning, belong to textile machine.
Electrical spindle for centrifugal spinning is a kind of centrifugal spindle that is directly driven by single-motor, and it is the key equipment that uses in the viscose long fiber spinning.The structure of original electrical spindle for centrifugal spinning as shown in Figure 1, it mainly is made up of tophan box (1), wool felt collar (2), solid shafting (3), hollow shaft (9), drive motors rotor (4), stator (5), lower bearing (6), upper bearing (metal) (10), lubricating cup (7), bracing frame (8) etc.Though this electrical spindle for centrifugal spinning has experienced the test of many decades production practices, because some the intrinsic weakness in the itself design cause the breakdown rate height, motor, damage of bearings are serious, big energy-consuming.As, original spinning electric ingot adopts hollow shaft-solid shafting twin shaft cone match location and transmits moment of torsion, when electric ingot starts (or braking), the hollow shaft that is fitted in together with drive motors is under acceleration (or deceleration) state, the solid shafting that is assembled together with tophan box then has an inertia that keeps former static (or uniform rotation) situation, this very easily causes the cone match of bearing moment of torsion impaired, thereby causes whole electric ingot to damage.For another example, the wool felt collar of original spinning electric ingot had both played the seal protection effect that prevents that corrosive water, vapour, gas enter electric ingot inside in the external environment condition, was again an aiding support, was a vitals in original electric ingot.When but electric ingot is worked, because the long-term contact friction of the solid shafting of high speed rotating and static wool felt collar has caused bigger energy consumption, and because the wearing and tearing and the distortion of wool felt collar, cause system vibration progressively to strengthen again, and then cause the damage of motor and bearing.
The investigation of the chemical fibre factory of domestic several employing electrical spindle for centrifugal spinning is shown that the fault rate of original electric ingot is about 0.003/ day according to us, service worker labour intensity is big, and maintenance cost is surprising.
Characteristics of the present invention are original electrical spindle for centrifugal spinning has been done following important improvement:
The structure of former hollow shaft-solid shafting twin shaft cone match location and transmission moment of torsion is substituted with single axle, owing to saved high hollow shaft of processing request and cone match between hollow shaft-solid shafting, thereby improved the axiality of rotation system, avoided damaging the fault that causes owing to hollow shaft and solid shafting mating surface.
The lower bearing of novel spinning electricity ingot can be rolling bearing, also can be sliding bearing, particularly can adopt the spiral grooved bearing of full-film lubrication.When adopting the helicla flute lower bearing, electric ingot has been avoided direct contact the between axle and the bearing at work fully, thereby has improved bearing life, has reduced energy consumption.
The drive motors of novel spinning electricity ingot adopts energy-efficient asynchronous machine or synchronous motor, compares with the drive motors of original electric ingot, and electric efficiency has had raising.
The viscous damper of novel spinning electricity ingot employing elastic construction has substituted the wool felt collar in original electric ingot.Test is fixed factually, nearly tens watts to tens watts of the energy consumptions that causes owing to the wool felt collar in original electric ingot.Therefore this improvement reduces the power consumption of novel spinning electricity ingot, and has improved the stability and the reliability of whole rotation system.
Novel spinning electricity ingot has also increased the precision between two bearings, makes upper bearing (metal) as far as possible near tophan box and be hidden among the cup type rotor of drive motors.Experiment showed, that such structure for the running accuracy that improves rotation system, reduces the load of upper bearing (metal), the possibility that the minimizing motor " is swept thorax " is useful.And in original electric ingot, because integrally-built restriction, such improvement is impossible.
One of embodiments of the invention as shown in Figure 2.It mainly is made up of with supporting system (10), bracing frame institutes such as (11) tophan box (1), rotating shaft (2), drive motors rotor (3), stator (4), upper bearing (metal) (5), supporting diaphragm (6), lower bearing (7), labyrinth-type excluder (8), outer containment vessel (9), following damping.Wherein lower bearing (7) has adopted the spiral grooved bearing of full-film lubrication, and upper bearing (metal) (5) adopts rolling bearing.Because the damping action of damping oil has absorbed, has reduced the vibration of rotation system, thereby guaranteed the stable operation of system in the elastic return effect of supporting diaphragm (6) and following damping and the supporting system (10).For preventing that harmful water, vapour, gas etc. in the external environment condition from entering electric ingot inside, designed labyrinth-type excluder simple in structure, easy to process (8) in the tophan box bottom.Preliminary experiment is the result show, the fault rate of new electric ingot can drop to original electric ingot fault rate 1/5 or lower, the original electric ingot of energy consuming ratio reduces about 5%.
Electrical spindle for centrifugal spinning of the present invention has reliable and stable, the failure rate is low of running, the life-span is long, power consumption economizes, simple in structure, make the advantages such as convenient.
