Abstract
The utility model discloses a false twisting friction plate for a terylene fibre processing false twisting machine, which comprises an aluminium alloy round plate body provided with a center hole, and a ceramic friction ring which adopts the differential of arc oxidation technique to integrally fix on the outer circumference of the plate body. The false twisting friction plate has the advantages of good wearing resistance, high rigidity, light weight, long service life and wear resistant material conservation.
Description
Technical field
The utility model relates to a kind of terylene thread processing false twister, the special-purpose navel of especially a kind of false twister.
Background technology
It is knitting and woven for terylene be can be used for, must improve the material property of terylene thread, make terylene be deformed into the low textured yarn that plays, method commonly used has false twisting method, stuffer box method, the method for nuzzling up, moulding method etc. several, wherein based on the false twisting method, it is to adopt false twister that the two ends of polyester filament are fixed, and realizes distortion and drive the rotation of terylene tow at the middle part with the false twisting frictional disk.Because the high speed rotating of false twisting frictional disk, so frictional disk very easily weares and teares.
Using comparatively widely at present, the false twisting frictional disk can be divided into this several classes: the one, constitute by homogenous material, the disk of the band centre bore that constitutes as single ceramic material, this false twisting frictional disk is heavier, what be not in the friction position all is the material with higher frictional behaviour, has caused the waste of material; Another kind is the disk of the band centre bore that is made of single polyurethane, and the hardness of this false twisting frictional disk is low, wear no resistance, and service life is short; The 2nd, disc surfaces compound the friction material formation, Hardmetal materials as spraying abrasion-proof on the disk body of synthetic resin or aluminium alloy, but it is not tight that the sprayed coating of the false twisting frictional disk of this structure combines with disk body, when friction, come off easily, reduced service life, and owing to adopted carbide alloy, on the high side.
Therefore, up to now, find that a kind of ABRASION RESISTANCE is good, hardness is high, the false twisting frictional disk of in light weight, long service life and saving high-abrasive material becomes the current problem of needing solution badly.
The utility model content
The shortcoming that the purpose of this utility model is to overcome above-mentioned prior art provides that a kind of mill property is good, hardness is high, the false twisting frictional disk of in light weight, long service life and saving high-abrasive material.
The purpose of this utility model is achieved in that
A kind of false twisting frictional disk comprises the disk body and the drag ring that contain centre bore, and this drag ring integrally is fixed on the excircle of disk body;
Wherein drag ring is to be made of ceramic material, and it is to adopt differential arc oxidization technique integrally to be fixed on the excircle of disk body.
Differential arc oxidization technique, be meant on the basis of common anode oxidation, utilize the reaction that arc discharge strengthens and activation takes place on anode, thereby form the method for the intensified ceramic film of high-quality at the surface of the work that with aluminium, titanium, magnesium metal and alloy thereof is material, be by on workpiece, applying voltage with special-purpose mao power source, the metal and the electrolyte solution of surface of the work are interacted, form micro-arc discharge at surface of the work, under the effect of factors such as high temperature, electric field, the metal surface forms ceramic membrane, reaches the purpose that surface of the work is strengthened.
The utility model has following advantage than prior art:
The utility model makes the material lighting effectively that is not in the friction position because adopted the less aluminium alloy stock of density as the disk disk body, has also reduced the utilization of high-abrasive material; In addition, adopt differential arc oxidization technique integrally to be solidificated on the excircle of disk body the drag ring of ceramic material, promptly guaranteed original anti-wear performance, also have following advantage:
(1) improved the case hardness of material significantly, microhardness reaches as high as 3000HV 1000 to 2000HV, can compare favourably with carbide alloy, substantially exceeds the hardness of high-carbon steel, high-alloy steel and high-speed tool steel after the heat treatment;
(2) good heat resistance and corrosion resistance.This has fundamentally overcome the shortcoming of aluminum alloy materials in application;
(3) the good insulation performance performance is arranged, insulaion resistance can reach 100M Ω;
(4) matrix growth in situ ceramic membrane, in conjunction with firm, ceramic membrane is evenly fine and close, the service life that can effectively improve the false twisting frictional disk.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.Among the figure, centre bore 1, aluminium alloy disk disk body 2, ceramic drag ring 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further details.
Embodiment: a kind of false twisting frictional disk, comprise the aluminium alloy disk body 2 and the ceramic drag ring 3 that contain centre bore 1, this pottery drag ring 3 is to adopt differential arc oxidization technique integrally to be fixed on the excircle of disk body.
Wherein differential arc oxidization technique by deoil, steps such as cleaning, differential arc oxidation, cleaning, sealing realize, applying high voltage specifically in the alkalescent electrolyte solution makes it produce the process of potteryization drag ring 3 on the surface of aluminium alloy disk disk body 2, its potteryization drag ring 3 hardness height can reach 1000 to 2000HV.
Claims (2)
1, a kind of false twisting frictional disk comprises the disk body that contains centre bore, it is characterized in that also comprising drag ring, and this drag ring integrally is fixed on the excircle of disk body.
2, false twisting frictional disk according to claim 1 is characterized in that drag ring is to be made of ceramic material.
