Abstract

The utility model discloses an unsymmetrical type steel wire ring used for a plane steel collar. The unsymmetrical type steel wire ring used for the plane steel collar is in a ring-shaped structure and provided with an opening at the lower end. The unsymmetrical type steel wire ring used for the plane steel collar comprises an ab arc line section inner track arranged on the right side and a cd arc line section outer track arranged on the left side. The lower end of the ab arc line section inner track extends towards the left lower side to be provided with an ef straight line section support leg. An included angle between the ef straight line section support leg and a vertical shaft is alpha, and the alpha is equal to 5-30 degrees. The length of the ef straight line section support leg is h, and the h is equal to 0.5-2.5 millimeters. The ef straight line section support leg and the ab arc line section inner track are transited through a round arc, wherein the radius (R) of the round arc is 0.2-0.8 millimeter. The structure enhances the contact length of the steel wire ring and the steel collar, ensures stable operation of the steel wire ring on the steel collar, prolongs service life of the steel wire ring and the steel collar, reduces broken ends, and improves spinning quality.

Description

A kind of Plane Ring asymmetrical type steel traveler

Technical field

The utility model relates to the parts on the Weaving device, is specifically related to the asymmetrical type steel traveler that a kind of Plane Ring is used.

Background technology

Rings and steel traveler are requisite parts in the cotton spinning apparatus, and rings is annulus spare, comprise Plane Ring and Conical rings.Figure 1 shows that Plane Ring, Figure 2 shows that and the matching used common symmetric form steel traveler of Plane Ring, in conjunction with Fig. 3 as can be known, yarn 3 is with steel traveler 2 high speed rotary on rings 1, the centrifugal force that produces is close on the inner track of rings 1 steel traveler 2 and moves, and steel traveler 2 is unsettled on outer track.

In the prior art, tens kinds of models such as FO type, O type, G type, 6802 types, 6903 types are arranged with the matching used steel traveler of Plane Ring, but no matter how the cast of steel traveler changes, steel traveler all adopts symmetrical structure (as shown in Figure 2), be ab section and cd section left-right symmetry, its ab section or cd section all can be used as inner track or outer track uses, and steel traveler is regardless of inside and outside in use.Main Problems is: common symmetric form steel traveler and Plane Ring are used in conjunction with when spinning, and only have the part of the ab section (or cd section) of inner track to contact with rings, and its contact length only has 1.5～2.5mm.Because contact area is less, pressure is large, and rings, steel traveler wear and tear very fast, and service life is not long.

The utility model content

The utility model aims to provide the asymmetrical type steel traveler that a kind of Plane Ring is used, and can increase the contact length of rings and steel traveler, prolongs the service life of steel traveler and rings.

For this reason, a kind of Plane Ring asymmetrical type steel traveler that the utility model provides, loop configuration for lower ending opening, comprise the ab arc inner track that is positioned at the right side and the cd arc outer track that is positioned at the left side, key is: the lower end of described ab arc inner track left downside is extended with ef straightway leg, and the angle of ef straightway leg and vertical axes is α, α=5 °～30 °, the length of ef straightway leg is h, h=0.5～2.5mm; Ef straightway leg and ab arc inner track are the arc transition of 0.2～0.8mm by R.

Be preferably, the length of described ab arc inner track is greater than the length of cd arc outer track.

The utility model is by increasing the straightway leg in inner track one side, make the contact length of steel traveler and rings increase h (h=0.5～2.5mm), the flare of steel traveler when considering spinning, therefore the straightway leg is set up a α inclination angle, make the steel traveler flare after the straightway leg can keep contacting with the rings inwall.

Beneficial effect: can greatly reduce pressure and wearing and tearing, prolong the service life of steel traveler and rings, can prolong 0.5～1 times service life; Simultaneously can increase area of dissipation, not damage fiber, improve yarn quality; Spinning tension is stable, reduces broken end.

The specific embodiment

Below by embodiment, and by reference to the accompanying drawings, the utility model is described in further detail:

The asymmetrical type steel traveler of Plane Ring as shown in Figure 4, loop configuration for lower ending opening, by the ab arc inner track that is positioned at the right side, be positioned at the left side cd arc outer track and bc linkage section consist of, wherein, ab arc inner track and cd arc outer track are requisite two parts on the steel traveler.The lower end of ab arc inner track left downside is extended with ef straightway leg, and the angle of ef straightway leg and vertical axes is α, and α=5 °～30 ° are preferably 12 °; The length of ef straightway leg is h, and h=0.5～2.5mm is preferably 1.5mm; Ef straightway leg and ab arc inner track are preferably 0.3mm by the arc transition that R is 0.2～0.8mm.

Can adopt ab arc inner track and the symmetrical structure of cd arc outer track; Consider in the spinning process, ab arc inner track, ef straightway leg contact with rings, and cd arc outer track is unsettled, when design, preferably, ab arc inner track and cd arc outer track are asymmetric, the length of ab arc inner track is greater than the length of cd arc outer track, to guarantee that in steel traveler gross weight one regularly selected steel wire diameter is larger, with the life-span of further raising steel traveler.

In conjunction with Fig. 5 as can be known, when being used for spinning after asymmetrical type steel traveler and the Plane Ring assembling, yarn 3 is with steel traveler 2 high speed rotary on rings 1, the centrifugal force that produces makes on the ab arc inner track of steel traveler 2, the inner track that ef straightway leg is close to rings 1 and moves, and the cd arc outer track of steel traveler 2 is still unsettled.

The cast of considering existing symmetric form steel traveler is varied, and for adapting to different Spinning Varieties, for the asymmetrical type steel traveler, its inner track also can be with reference to doing different designs, so that extensive use.Plane Ring is in fact the remodeling that Plane Ring is used the symmetric form steel traveler with the asymmetrical type steel traveler, Plane Ring has tens kinds of models such as FO type, O type, G type, 6802 types, 6903 types with the symmetric form steel traveler, the asymmetrical type steel traveler correspondingly can be designed to tens kinds of models so.When the design plane rings is used the asymmetrical type steel traveler, if adopt ab arc inner track and the symmetrical structure of cd arc outer track, then the inside and outside runway of ab arc inner track, cd arc outer track and symmetric form steel traveler is basically identical, and increases ef straightway leg in the lower end of ab arc inner track; If adopt the length of ab arc inner track greater than the structure of the length of cd arc outer track, its cd arc outer track is more smaller than the outer track of symmetrical shaped steel wire circle, and the inner track of ab arc inner track and symmetric form steel traveler is basically identical, and increases ef straightway leg in the lower end of ab arc inner track.
