Abstract

A winding spindle comprises a spindle housing, a spindle shaft, two rolling bearings, a fixed screw and a spindle shaft handle, wherein the spindle housing is provided with a snap tube rubber ring, the spindle shaft passes through the spindle housing, the two rolling bearings are arranged at the two ends of the spindle shaft, the fined screw is mounted at the front end of the spindle shaft and the spindle shaft handle is provided at the rear end of the spindle shaft. An oil cover is placed on the outer side of the bearing and a bearing cover is used to push against the inner ring of the bearing. The utility model is characterized in that the winding spindle further consists of an elastic body and a metallic covering layer. The elastic body can produce axial force and the metallic covering layer is provided on the conic surface of the spindle housing. The inner wall of the spindle housing forms a special-typed cavity in the position of the outer side of the bearing. The oil cover and the bearing cover form a dust-proof engagement body of labyrinth type inside the special-typed cavity. The elastic body pushes against the position between the bearing cover and the spindle shaft handle after being compressed to prevent the bearing and the spindle body from moving freely. The utility model adds the anti-abrasive metallic covering layer on the conic surface of the spindle housing, thereby avoiding the winding position of yarn arranged on a yarn tube departures the fixed range and guaranteeing the quality. In addition, the oil cover and the bearing cover form a dust-proof engagement body of labyrinth type inside the special-typed cavity, thereby increasing the oil tight and dust-proof effect of the rolling bearing.

Description

A kind of Winding spindle

(1) technical field

The utility model relates to a kind of doff spindle.

(2) background technology

As shown in Figure 1, the patent No. is that 902070370.1 disclosed a kind of utility model names are called " with the circular cone paper tube type spindle of rolling bearing supporting ", it comprises that rolling bearing 4 and that spindle blade 1, two that a spindle shell 6, with button pipe rubber circle 5 passes described spindle shell is installed in described spindle blade 1 two ends respectively is arranged on the hold-down screw 12 of described spindle blade 1 front end, it is conical 15 that the inwall of described spindle shell 6 is made in described bearing outside, is placed with an oil cap 3 in the described bearing outside and props up the inner ring of described bearing 4 with a bearing cap 2.Though the spindle of said structure has its advantage, that is: use rolling bearing, once the lubricating grease of Jia Ruing can use one, two year continuously, when saving the oil supplier; In addition, because the inside and outside circle of rolling bearing axially obtains the location, make can not produce between spindle blade and spindle shell to give birth to move axially, prevented to climb the generation of the bad tube of head yarn, reduction is weaved, the end breakage rate in the preparation, twisting operation.

But, the plastics conical surface of above-mentioned spindle shell in use with fixed cover paper tube thereon in wall friction and cause outer through dwindling gradually, paper tube is moved at the big extreme direction of ingot body, especially obvious especially in the little model of cone angle, make the winding position of yarn on spool depart from fixed range gradually.In addition, because paper tube in use has a large amount of suede dirt to produce, grease can be blotted after entering bearing bore, especially after in a single day spindle stops using one period date, because of ambient humidity is very high, the very fast generation corrosion in bearing periphery is after re-using, brown iron oxide will roll bad bearing, thereby causes the spindle cisco unity malfunction.

(3) summary of the invention

Of the present utility modelly be to provide a kind of Winding spindle, it can not only avoid the winding position of yarn on spool to depart from fixed range, and can improve the oil seal of rolling bearing and the improvement of dustproof effect.

It comprises that the rolling bearing and that ingot axle, two that a spindle shell, with button pipe rubber circle passes described spindle shell is installed in described ingot axle two ends respectively is arranged on the hold-down screw of described ingot axle front end and the ingot footstalk of rear end a kind of Winding spindle provided by the utility model, be placed with an oil cap in the described bearing outside, and be the inner ring that props up described bearing with a bearing cap, be characterized in: it comprises that also one produces the elastomer of axial force and the cover layer on the spindle shell conical surface; The cavity that the inwall of described spindle shell is made in described bearing outside is special-shaped cavity; Described oil cap and bearing cap form mazy dustproof ligand in this abnormal shape cavity, that is: described oil cap is by being formed around body of oil cap body and oil cap body periphery, and its cross section is Shape, and it embeds in the wall of shell respectively around body; The cross section that described bearing cap is made up of large and small cylinder is Shape, the paxilla of bearing cap closely passes the oil cap body, and makes the big cylinder of bearing cap prop up the inner ring of described bearing; Contact is between bearing cap and ingot footstalk behind the described elastomer pressurized.

Above-mentioned Winding spindle, wherein, the cover layer on the conical surface of spindle shell is a metal cladding.

Owing to adopted above-mentioned technical solution, on the spindle shell conical surface, increase anti abrasive metal cladding, thereby avoided the winding position of yarn on spool to depart from fixed range, guarantee in the operating period, no longer to need repairing or adjust.In addition, the cavity of making in described bearing outside at the inwall of described spindle shell is special-shaped cavity, makes being engaged in of bearing cap and oil cap form mazy dust seal in this abnormal shape cavity, thereby has improved the oil seal and the dustproof effect of rolling bearing.

(4) description of drawings

Fig. 1 is the structural representation of existing circular cone paper tube type spindle with rolling bearing supporting;

Fig. 2 is a structural representation of the present utility model.

(5) specific embodiment

See also Fig. 2, the utility model, that is: a kind of Winding spindle, the utility model comprises ingot axle 1, spindle shell 6.Embed one in the middle part of spindle shell 6 and buckle pipe rubber circle 5, certain button pipe rubber circle 5 also can have a plurality of, in order to the paper tube (in figure do not draw) of fixed cover on spindle shell 6; Spindle shell 6 central shafts are slightly larger than the straight hole of ingot axle 1 to having the aperture, and the both sides of straight hole respectively have a profiled holes 10.Spindle shell 6 is enclosed within on the ingot axle 1.Between the ingot axle 1 of the rear end of ingot axle 1 (from figure, being seen as left end) and spindle shell 6, be with successively from left to right rear bearing cover 2 ', back oil cap 3 ' and rolling bearing 4, wherein rear bearing cover 2 ' one ends prop up on the ingot footstalk 9 by elastomer 7, the other end props up on the rolling bearing 4, back oil cap 3 ' with spindle shell 6 tight fits.The outer ring of rolling bearing 4 props up the inwall end face of special-shaped cavity 10.

Between the ingot axle 1 of the front end of ingot axle and spindle shell 6, be with successively from left to right rolling bearing 4 ', preceding oil cap 3 ", front bearing retainer 2 " and gland 11, with screw 12 above-mentioned part is located; Even housing washer props up the inwall end face of special-shaped cavity, front bearing retainer 2 " prop up rolling bearing 4 ' inner ring, preceding oil cap 3 " with spindle shell 6 be tight fit.

Above-mentioned oil cap and bearing cap form mazy dustproof ligand, that is: oil cap is by being formed around body 22 of oil cap body and oil cap body 21 peripheries, and its cross section is

Shape, and it embeds in the wall of shell respectively around body 22; The cross section that bearing cap is made up of large and small cylinder 31,32 is

Shape, the paxilla 32 of bearing cap closely passes the oil cap body, and makes the big cylinder 31 of bearing cap prop up the inner ring of described bearing.

Spindle shell 6 is to be made of plastics, and its conical surface is provided with the metal tapered sleeve.

Behind elastomer 7 pressurizeds contact bearing cap 2 ' and ingot footstalk 9 between, make spindle on the ingot axle, guarantee not produce axially to move freely, this is significant to producing the tube yarn quality.
