Description
The utility model belongs to field of textile machinery, and particularly the improvement to the electrical spindle for centrifugal spinning structure designs.
Traditional electrical spindle for centrifugal spinning mainly is made up of parts such as tophan box, wharve, solid shafting, hollow shaft, rotor, motor stator, upper bearing (metal), lower bearing and flyer and bearings.Though this electric ingot compact conformation, the maintenance also more convenient, the serious problems that energy consumption is big, spoilage is high, maintenance cost is high are arranged.This is because the defective on its structural design causes.For example, for supplying lubricant just, its upper bearing (metal) and lower bearing all are biased in the below of rotor, barycenter away from tophan box, and the span between two bearings is very little again, because the quality and the mass eccentricity of tophan box and spinning cake are all bigger, cause bearing load excessive, thereby damage of bearings " is swept thorax " with motor, and (rotor and stator grazing mutually) phenomenon are all very serious; For another example, its solid shafting and hollow shaft adopt a less cone match location and transmit moment of torsion, because the rotary inertia of tophan box and spinning cake is very big, in startup and reversing braking process, very easily cause the conical surface to bite, cause solid shafting and tophan box to depart from pivot more, and cause vicious circle.ZL92230934.5, patents such as ZL95240538.5 and ZL95240539.3 are improved above-mentioned electrical spindle for centrifugal spinning, and the upper bearing (metal) of the centrifugal electric ingot of tradition is displaced to the rotor top by the below of rotor.Undoubtedly, this is useful to improving the shaft strength state.But also have aspect the master-plan following not enough: for example power saving is not considered in the design of patent 92230934.5, though and 95240538.5 paid attention to economize on electricity, sacrificed startup and braking ability to cause a process excessively to prolong the waste silk increase; In addition, tophan box and solid shafting adopt feather key to connect, and, might occur " flying jar " phenomenon sometimes though mounting or dismounting are convenient, and promptly when field management was not good enough, tophan box caused major accident because of unbalance flying out automatically; In addition, this design directly matches upper bearing (metal) with flyer, though this simplifies the structure, cause flyer to wear and tear too early easily, has shortened the service life of flyer.
The purpose of this utility model is, under the prerequisite of the advantage that fully keeps existing all types of centrifugal electric ingots, overcome the existing shortcoming of prior art to greatest extent, make electric ingot have excellent comprehensive performances, so that provide another kind of economical and practical electric ingot for the technological transformation of viscose filament yarn industry equipment at aspects such as manufacturing cost, economize on electricity, startup and braking, run stability, reliability, maintenanceabilities.
