The spindle bottom comprises a radial spindle bottom and an axial spindle bottom, the spindle bearing components and the spindle bottoms are connected into an integral whole through the metal elastic tube, and the spindle insert also comprises a shim, a bearing spring and a bearing bottom positioned below the axial spindle bottom in sequence. The bearing spring is a ring spring; the bearing bottom comprises three sections of columns with different diameters, wherein the diameter of one section is matched with the internal diameter of the bearing spring and is positioned in the bearing spring, the diameter of the second section is matched with the internal diameter of the mental elastic tube and leans close to the inner wall of the mental elastic tube, the diameter of the other section is positioned at the lower end opening of the mental elastic tube. The spindle insert can return to the original position after the spindle is impacted by the external force or the overall height is decreased, the spindle insert is provided with more strong vibration absorbing performance and vibration resistance performance, which can ensure the dynamic balance and the stability when the spindle runs at a high speed, and the requirements of the high-speed spinning machine to the spindle can be met.

Description

A kind of bolster of cotton spinning ring throstle hi-speed spindles

Technical field

The utility model relates to the bolster of textile machine equipment middle cotton spinning ring hi-speed spindles, and it is applicable to high-quality spinning equipments such as closely spinning fine spining machine, collective's doffing spinning machine.

Background technology

Closely spin, high-quality spinning equipment such as collective's doffer is the R﹠D direction of following fabric machinery.Spindle is the critical component of all kinds of fine spining machine yarn qualities of influence as one of important components in the Textile Machinery.Bolster is the important supporting member of spindle, and its structural behaviour directly has influence on the spinning quality of spindle.Its supporting form roughly has two kinds at present, and a kind of is the interconnection system bolster that adopts the metallic elastic pipe, and its basic structure is to adopt the metallic elastic pipe to add lower support as flexible member, is called at the bottom of the awl nest formula ingot; The spindle that adopts this form bolster because of its " awl nest formula " ingot at the bottom of in radial clearance bigger, the taper seat of ingot point at the bottom of the ingot of the effect lower edge of out-of-balance force climb, cause the spindle play, and the effect of absorbing wind spring lags behind, influence the vibration performance of spindle, so rotating speed is lower,, the needs of present high-speed spinning have not been fitted into generally at 8000 rev/mins～18000 rev/mins.Another kind of supporting form is the bolster of form at the bottom of the divergence type ingot, adopt the spindle of this kind bolster on rotating speed, can reach 10000 rev/mins～22000 rev/mins, reach as high as 25000 rev/mins, though the spindle of this form bolster can overcome the defective of spindle at the bottom of " awl nest formula " ingot, but the spindle of this divergence type ingot bottom structure form is not owing to there is buffer unit, can not bear the moment impulse force of collective's doffing spinning machine when last pipe, so do not fit into the application of collective's doffing spinning machine.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of bolster of cotton spinning ring throstle hi-speed spindles, it is applicable to collective's doffing spinning machine, guarantee that spindle is being subjected to can quickly recovering to original position after external impacts, the whole height decline, has very strong absorbing, resistance to shock and spindle and keep good dynamic balancing and stability when rotating at a high speed.

For solving the problems of the technologies described above, the bolster of the utility model cotton spinning ring throstle hi-speed spindles comprises and having at the bottom of spiral fluted metallic elastic pipe, spindle axis bearing assembly and the ingot, at the bottom of the described ingot by forming at the bottom of the ingot at the bottom of the ingot radially and axially, described metallic elastic pipe fuses at the bottom of with spindle axis bearing assembly and ingot, also comprise pad, bearing spring and backing, described pad, bearing spring and backing are positioned at the metallic elastic pipe of the beneath face of described axial ingot successively.

Above-mentioned bearing spring is a ring spring.Above-mentioned backing is three sections reducing cylinders, one section diameter and bearing spring internal diameter coupling also are positioned at described bearing spring, another section diameter and described metallic elastic bore mate and press close to the inwall of metallic elastic pipe, and one section diameter is positioned at described metallic elastic pipe lower ending opening place again.

Because the bolster of cotton spinning ring throstle hi-speed spindles of the present utility model has adopted technique scheme, promptly axially increasing pad, bearing spring and backing under the ingot, make spindle be subjected to quickly recover to original position after external impacts or whole height descend, it has stronger absorbing, resistance to shock, guaranteed dynamic balancing and the stability of spindle when rotating at a high speed, satisfied of the requirement of high speed frame spindle.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is the structural representation of the bolster of the utility model cotton spinning ring throstle hi-speed spindles.

The specific embodiment

As shown in Figure 1, the bolster of the utility model cotton spinning ring throstle hi-speed spindles comprises at the bottom of metallic elastic pipe 5, spindle axis bearing assembly and the ingot that has helicla flute 51, described spindle axis bearing assembly comprises bearing washer 1, wave-shaped ring 2, spindle bearing 3 and top chock 4, at the bottom of the described ingot by at the bottom of the ingot radially 6 and axially 7 form at the bottom of the ingot, described metallic elastic pipe 5 fuses at the bottom of with spindle axis bearing assembly and ingot, also comprise pad 8, bearing spring 9 and backing 10, described pad 8, bearing spring 9 and backing 10 are positioned at the metallic elastic pipe 5 below 7 at the bottom of the described axial ingot successively.

But 9 one ring springs of above-mentioned bearing spring.Above-mentioned backing 10 is three sections reducing cylinders, one section diameter and bearing spring 9 internal diameters coupling also are positioned at described bearing spring 9, another section diameter and described metallic elastic pipe 5 internal diameters mate and press close to the inwall of metallic elastic pipe 5, and one section diameter is positioned at described metallic elastic pipe 5 lower ending opening places again.

For present novel high-performance frame, as collective's doffing spinning machine, it is high automation and novel spinning equipment at a high speed, the form that adopts similar mechanical arm is to the spindle of ingot more than 1,000 while tube drawing, go up pipe simultaneously, this just requires spindle promptly to want to bear the instant impact of pipe on the mechanical arm, requires spindle again after bearing longitudinal impact force, can return to original state immediately when next spinning.The bolster of this cotton spinning ring throstle hi-speed spindles is exactly the special above spindle design that is, its adopt bearing spring alleviated spindle tube drawing and on suffered various impulsive forces during pipe, stability when having guaranteed the spindle spinning, through facts have proved that the spindle of using this kind bolster can bear the instant impact of pipe on the mechanical arm, and after bearing longitudinal impact force, can return to original state at once, and this kind bolster spindle also can adapt to following frame also can keep its stability under high rotation speed operation, i.e. short arc and long service life.
