Description

A kind of spinning spindle

Affiliated technical field

The present invention relates to the bolster structure of a kind of spinning spindle, particularly spinning spindle.

Background technology

Existing spinning spindle mainly is made up of bar dish conjunction, top chock conjunction, bolster conjunction and bolster.Bar dish conjunction is the yarn twisting parts of rotation at a high speed; Top chock conjunction and bolster conjunction are upper and lower two supports of bar dish conjunction, to guarantee the normal operation of bar dish conjunction; The function of bolster is the housing that miscellaneous part is installed body and splendid attire spindle lubricant.Lubricating oil is used for lubricated upper and lower two bearing pairs in the ingot.According to the range of spindle types difference, added once oil in 5 ~ 15 days during use, be called a filling cycle.

Since the elastic ring separated type spindle was finalized the design from about 1830, simple in structure with it, with low cost, easy maintenance had good performance under the situation of low speed underloading, be widely used.But its radial support rigidity is little, can not bear high-speed overload, and when ingot speed 〉=16000 rev/min, the remarkable variation of spindle behavior in service numb hand occurs, shakes the head, phenomenon such as end breakage rate sharp increase.For addressing the above problem, China begins to promote and uses metallic elastic pipe interconnection system spindle in the eighties of last century the eighties, and this type spindle has solved the shortcoming of elastic ring separate type, and ingot speed can reach≤and 18000 rev/mins.

Elastic ring separate type and metallic elastic pipe interconnection system pluses and minuses are respectively arranged: elastic ring separate type radial rigidity is less, but the space is big in the ingot, can hold more lubricating oil, and filling cycle is longer, general 10 ~ 15 days.Metallic elastic pipe interconnection system radial rigidity is bigger, but this structure has occupied in the ingot very large space, and it is less to hold lubricating oil in the ingot, and filling cycle is short, is generally 5 ~ 8 days.Along with the textile industry intensified competition, require the high rotating speed of spindle, big load, little amplitude, low use cost.Therefore, the spindle that uses at present can not satisfy fast-developing textile industry requirement.

In order to prolong filling cycle, the scheme that patent 200420116769.1 proposes can overcome the above problems preferably, but at the elastic ring separated type spindle.

Patent 200510099787.2 also preferably resolves the filling cycle problem at the outer attached oil container scheme that metallic elastic pipe interconnection system spindle proposes.But the sealing of oil container is difficulty comparatively, and be easy to adhere dust and flower hair influence spinning quality and workshop condition; Oil container has occupied the space between the spindle, is unfavorable for cleaning operation; The loading and unloading of oil container are also inconvenient, and saving personnel from damage has bigger suggestion.

For head it off, the invention provides a kind of: radial rigidity is big, can adapt to the high-speed overload spinning requirement; Oil storage space is big in the ingot, can prolong filling cycle greatly; Keep external dimensions constant, help the cotton mill production operation; Axial buffer reduces the spindle of big yarn breakage.

The technical scheme that the present invention is adopted for its technical problem of solution is: a kind of spinning spindle comprises bar dish conjunction 1, top chock conjunction 2, bolster conjunction 3 and bolster 4, it is characterized in that:

33 close-fittings are contained in the center sleeve 32 at the bottom of the ingot, and a flexible member 31 is installed at center sleeve 32 two ends respectively, between the two elastic elements 31, center sleeve 32 outsides are equipped with absorbing wind spring 37 and constitute bolster conjunction 3.

Above-mentioned spinning spindle is characterized in that two flexible members, 31 endoporus and center sleeve 32 two ends cylindricals closely cooperate, and external diameter and bolster 4 endoporus closely cooperate.

Above-mentioned spinning spindle is characterized in that center sleeve 32 upper ends are provided with radial protrusion thing 34, stops flexible member 31 to break away from center sleeve 32 from top.

Above-mentioned spinning spindle is characterized in that flexible member 31 radial elastic coefficients 0.6≤Kz≤1.8mm/kg.

Above-mentioned spinning spindle is characterized in that flexible member 31 axial elasticity coefficients 0.6≤Kj≤1.8mm/kg.

Above-mentioned spinning spindle is characterized in that 33 endoporus tips at the bottom of the ingot are 1.5～2.5 to the ratio of upper and lower flexible member 31 central point distances.

The invention has the beneficial effects as follows: improved the radial rigidity of bolster, spindle is reached more than 18000 rev/mins, spun big yarn and no longer shake the head; The spindle filling cycle can reach 90～120 days, prolongs 8～15 times of filling cycles, has saved lot of manpower and material resources; The effect of flexible member axial buffer has improved the spindle operating condition, 20000 rev/mins of full packages, ingot speed, spool upper end amplitude≤0.30mm; Ingot does not have adjunct outward, more helps the operation of spinning.

Compare with existing spindle:

Working speed can reach 20000 rev/mins;

Filling cycle can reach 3～4 months.
