Abstract
The utility model relates to a steel wire circle used for cotton and wool spinning industries. An opening elastic ring can be a symmetrical steel wire circle with two contact points, wherein, D is equal to 3 to 8 mm, H/ D is less than 0.65, beta is equal to 5 to 25DEG, R is bigger than 1.6, r <2> is equal to 0.9 mm, and r <2> is equal to 0.6 to 1.5 mm. The opening elastic ring can also be an unsymmetrical steel wire circle with two contact points, wherein, D is equal to 3 to 8 mm, H is equal to (0.6 to 1.2) times of the D, beta is equal to 5 to 25DEG, R is equal to 1.5 to 6.5, r is equal to 0.3 to 0.6 times of the R, and r <2> is equal ro 0.3 to 0.6 times of the R. The opening elastic ring can also be an unsymmetrical steel wire circle with a plurality of contact points, wherein, D is equal to 3 to 8 mm, H is equal to 4 to 12 mm, h is equal to (0.5 to 0.8) times of the H, beta angle is 0 to 35DEG, R is equal to 1.5 to 6.5, r <1> is equal to (0.3 to 0.6) times of the R, r <2> is equal to (0.3 to 0.6) times of the R, and r <3> is equal to (0.1 to 0.4) times of the R. The utility model has the advantages of long service life and lower end-breakage rate.
Description
The utility model relates to a kind of steel traveler of using on cotton spinning and woolen industry ring spinning frame and the twisting machine of being used for.
At present employed steel traveler mainly is that geometric parameters such as size according to the cooperating of height of C.G. (or the height at inertial force system center) and runway radius of curvature, yarn path and base angle design in the textile industry, but because its structure is not pressed the operation principle design of rings runway curve, therefore not only service life is low but also end breakage rate is high when spinning.
In view of above-mentioned weak point the purpose of this utility model of the prior art is to provide a kind of its geometry is the steel traveler that designs according to spinning tension characteristic principle.
The purpose of this utility model mainly realizes by following measure: a kind of steel traveler of using on cotton spinning and woolen industry ring spinning frame and the twisting machine of being used for, it is an open elastic ring, it is characterized in that: 2 contact symmetric figure steel travelers, D=3～8 millimeter wherein, H/D＜0.65, β=5～25 °, R＞1.6, r
1=0.9 millimeter, r
2=0.6～1.5 millimeters; Perhaps 2 the asymmetric shape steel travelers of contact, wherein D=3～8 millimeter, H=(0.6～1.2) D, β=5～25 °, R=1.5～6.5, r=(0.3～0.6) R, r
2=(0.3～.6) R; Perhaps multiple spot contact steel traveler, wherein D=3～8 millimeter, H=4～12 millimeter, h=(0.5～0.8) H, β angle be 0～35 °, R=1.5～6.5, r
1=(0.3～0.6) R, r
2=(0.2～0.6) R, r
3=(0.1～0.4) R.
The geometry of its open elastic ring of steel traveler of the present utility model can be divided into three parts, i.e. outer rings
Collar
And inner ring
Can be positioned at the steel traveler inner ring of rings inner track one side
Then have and rings primary runway curve and the similar curve of easement curve, like this it can fully contact with rings so that rings to its supporting.This inner ring can be the two circular curves of defg that interior pin is arranged, and also can be the def semi arch curve of pin in not having.The steel traveler outer ring abc that can be positioned at rings outer track one side can be corresponding with rings outer track curve with the geometry of collar cd.Preferably, this part also to make the horizontal level of steel traveler in the revolution inertial force system the spacious yarn path in selected interval range except that being had.The size of steel traveler and angular range are as follows for this reason: 2 of a contact symmetric figure steel traveler, one of footing β=5～25 of pin ° in overall width D=3～8 of steel traveler millimeter, H/D＜0.65, the steel traveler, radius of curvature of cooperating with the rings runway R＞1.6, yarn pass through the radius of curvature r that locates
1＜0.9, two r of the radius of curvature that cooperates with the rings runway
2=0.6～1.5; The asymmetric shape steel travelers of 2 of b contact, overall height H=(0.6～1.2) D of D=3～8 millimeter, steel traveler, β=5～25 °, R=1.5～6.5, r
1=(0.3～0.6) R, r
2=(0.3～0.6) R; C multiple spot contact steel traveler is in cast height h=(0.5～0.8 in the rings runway outside when D=3～8 millimeter, H=4～12 millimeter, a kind of specific asymmetric shape steel traveler operation) H, β angle be 0～35 °, R=1.5～6.5, r
1=(0.3～0.6) R, r
2Three r of=(0.3～0.6) R, the radius of curvature that cooperates with the rings runway
3=(0.1～0.4) R.
