Abstract

The utility model relates to a universal self-adjustable centering high-speed spindle with three damping, wherein the spindle is used for a spinning frame of a textile machinery. The utility model comprises a spindle blade disk, a spindle lining, a spindle footstep, damping rings, an upper rolling bearing and a lower rolling bearing, wherein the spindle blade disk is inserted on the spindle lining; the spindle lining end is provided with the upper rolling bearing; the spindle lining is tightly matched in the spindle footstep; an inner cavity of the spindle footstep is filled with spindle oil. The utility model is characterized in that the lower end of the spindle lining and the upper part of a coil spring are provided with the damping rings, and the damping rings are sheathed between the spindle footstep and an elastic tube; the center of the bottom face of a spindle bottom is arranged on a convex tail coiling pad ring. Compared with the prior art, the utility model has the advantages that the three-damping form of three tubes causes the resonance and the self-excited vibration of the spindle to vanish, the spindle can normally spin in the rotating speed range of 2000 circles per minute to 23000 circles per minute, the running of the spindle is more steady, particularly, the amplitude of the spindle is largely less than the amplitude of the common spindle during high speed spinning and the utility model is adapted to the production of a plurality of breeds because the utility model has superstrength carrying capacity.

Description

Three damping self-regulated center hi-speed spindles

Technical field

The utility model belongs to technical field of textile machine, is specifically related to a kind of three general damping self-regulated center hi-speed spindles of textile machine spinning frame that are used for.

Background technology

Textile industry development in recent years is swift and violent, require high speed, efficient, high-quality, many kind, and the existing spindle range of speeds in market can not satisfy the demand in market fully at 8000～18000 rev/mins; Market to the requirement of the spindle range of speeds at 18000～22000 rev/mins.In addition, the needs of many kinds also require spindle speed very low, as: about 6000 rev/mins, the slow-speed of revolution also is a difficult problem to spindle, because the first critical speed district just at this moment, spindle produces resonance, vibrate greatly especially, is not suitable for spinning.Present employed spindle lower support all is to adopt single ring spring with being damping element, and damping intensity is not enough, during first critical speed, covibration is arranged, when reaching more than 18000 rev/mins, rotating speed often occurs unusually, as: spindle is play up and down, phenomenons such as vibration amplitude of spindle.

Summary of the invention,

The utility model is at the deficiencies in the prior art part, provide a kind of range of speeds from 2000 rev/mins～23000 rev/mins, vibrate little, can satisfy existing market at a high speed, three damping self-regulated center hi-speed spindles of the demand of efficient, high-quality, many kinds.

The utility model is to adopt following scheme to realize, three damping self-regulated center hi-speed spindles, include spindle shaft disk, bolster, bolster, damped ring, go up rolling bearing and following rolling bearing, spindle shaft disk inserts the bolster upper end, the bolster end is equipped with rolling bearing, and the bolster close-fitting is in bolster, and the inner chamber of bolster is full of bobbin oil, it is characterized in that: damped ring is equipped with on the lower end of bolster and the top of ring spring, is enclosed between bolster and the elastic tube.Bolster of the present utility model applies three dampings by the rubber-like lower support, and the one, damped ring is to make with nylon material, makes it possess little elasticity and strong damping capacity; The 2nd, ring spring is to make with metal, and the oil film between the circle of ring spring and circle produces strong damping capacity; The 3rd, at the bottom of the ingot and between the elastic tube design gapped, the oil film in the gap also can produce certain damping action.Owing to work on the three areas simultaneously, make the covibration of spindle the time and complete damped the sponging of self-excited vibration of spindle, and show superpower carrying energy through critical speed; In addition, at the bottom of the ingot and between elastic tube design gapped, the center of bottom surface is shelved on lifting up on the tail packing ring of convex at the bottom of the ingot.Lift up the tail packing ring by wrapping in the elastic tube tightly, " lifting up tail " then is stuck in the groove at the bottom of the ingot, rotates at the bottom of the ingot in order to preventing.When spindle shaft disk during at high speed rotary, owing at the bottom of the ingot level of freedom is arranged, can play the effect of the self-regulated centre of gyration, make the spindle shaft disk revolution more steady, especially the common spindle of amplitude ratio is much smaller when high-speed spinning.

The utility model compared with prior art has the following advantages: 1, adopt three-pronged three damping forms that the resonance of spindle and self-excited vibration are disappeared, spindle all can normally spin in 2000 rev/mins～23000 rev/mins the range of speeds; 2, owing to adopt three dampings and self-regulated center structure combining, the spindle running more becomes steadily, and especially the common spindle of amplitude ratio of spindle is much smaller during high-speed spinning; 3, because superpower bearing capacity is arranged, can adapt to many variety production.

The specific embodiment

With reference to the accompanying drawings embodiment is further described, present embodiment is to be used for illustrating of the present utility model, rather than the utility model is carried out any restriction.

Three damping self-regulated center hi-speed spindles are to be used for the general hi-speed spindles of textile machine spinning frame, and " three dampings " promptly adopts three kinds of damping forms, realized by damped ring 4, ring spring 5 and bobbin oil.Spindle shaft disk 1 (spindle shaft disk polished rod or aluminum casing is all applicable) inserts in the bolster 2, and damped ring 4 is equipped with on the top of the lower end of bolster 2 and ring spring 5, is enclosed between bolster 3 and the elastic tube 8, does high speed rotary by the last rolling bearing and the following roller bearings of bolster 2.Bolster 2 close-fittings are full of bobbin oil in the inner chamber of bolster 3 in bolster 3.Damped ring 4 usefulness nylon materials are made, and make it possess little elasticity and strong damping capacity; Ring spring 5 is to make with metal, at the circle of ring spring and the oil film between circle, can produce strong damping capacity; At the bottom of the ingot 6 and 8 designs of elastic tube gapped, the oil film in the gap also produces certain damping action, makes spindle in the covibration when the critical speed, as complete damped the sponging of the self-excited vibration of spindle.The center of bottom surface is shelved on lifting up on the tail packing ring 7 of convex at the bottom of the ingot.Lift up the tail packing ring and wrapped in tightly in the elastic tube 8, lift up tail and then be stuck at the bottom of the ingot in 6 the groove, rotate to prevent at the bottom of the ingot 6.
