Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a rotating ring for a spinning machine.
It is configured to rotate extremely smoothly during spinning and to minimize floating.

Conventionally, there have been belts to speed up the spindle rotation of spinning machines, rotary rings in which the ring is directly driven by a drive wheel to rotate, rotary links in which the periphery of the ring is held by bearings, and Various rotating rings have been proposed in which a sliding body is provided between a ring holder and a ring so that the rings can rotate together. However, all of the above-mentioned rotating links have the drawback that, compared to fixed rings, the links float unevenly and vibrate more frequently, resulting in thread breakage, which limits the number of revolutions of the spindle, making it impossible to improve productivity.

In addition, since the rotating ring is directly fixed to the ring rail, the rotational vibration that changes over thousands of cycles generated in the rotating body due to the rotation of the trapeller suspended on the ring 7 lunge is transmitted to the sliding part. is transmitted to the fixed part via.

For this reason, an irregular and excessive bearing reaction force is generated along with vibration on the sliding surface of the rotating ring, and the rotation of the rotating part becomes unstable, sometimes pulsating, or stopping. In extreme cases, the traveler may rotate in the opposite direction to the traveling direction of the traveler.

As shown in q), when the rotation of the rotating part of the rotary link becomes unstable, yarn breakage occurs frequently, yarn splicing becomes difficult, and the operability is greatly reduced.

Furthermore, due to the unstable rotation of the rotating ring and the running condition of the traveler, the swivel becomes unstable, leading to a decrease in yarn quality such as an increase in L1 yarn play, a decrease in yarn strength, and an increase in yarn unevenness, resulting in excessive bearing reaction. The generation of force causes abnormal shore wear of sliding + IIJs,
This caused a significant drop in the time of the rotating ring.

The present invention has been made to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

Embodiment 1 A ring co-rotating body 1 having a sliding collar on the upper outer peripheral surface, a ring fixing part 4 and a stopper 6 that are fitted and placed in a ring fitting hole of a ring rail 1. A rotating ring 6 is configured.

The above-mentioned rotating ring @ is a ring fixed 841 formed of polytetrafluoroethylene resin, and is rotatably loosely fitted so as to be in sliding contact with the outer periphery of one part of the ring rotating body 1onl and the bottom fiK of the sliding collar. A retaining ring b [removable Kl] having two notches in a groove provided all around the lower end is inserted to prevent the ring rotating body l from being pulled out from the ring fixing part 42P. I'm doing something like that.

The rotating ring 6 formed as described above is the ring rotating body 1
A sliding part tube is formed between the lower surface of the sliding collar and the upper part of the ring fixing part s4, and between the outer circumferential surface of the body part 8 of the link rotating body l and the inner circumferential surface of the ring fixing part 4. However, a sliding portion may be formed between the lower surface of the ring fixing portion 4 and the retaining ring.

Embodiment 2 As shown in FIG. 2, in the same manner as in Embodiment 1, an annular vibration absorbing member 10 made of silicone rubber is arranged in a hole to form a rotating ring.

Embodiment 8 As shown in No. 11iN, in the rotary ring 6 configured similarly to Embodiment 1, a concave #l11 t is formed over the entire circumference on the outer circumferential surface of the link fixing section 4 where it is inserted into the link rail 8.
An annular vibration absorbing member 1 (1) made of silicone rubber is arranged so as to be in contact with the lower surface of the flange part and fit into the groove 11. A well-circular vibration absorbing member 11 made of silicone rubber having an outer diameter slightly smaller than the inner diameter of the ring rail 8 fitting hole is fitted in contact with the vibration absorbing member 10 to form a rotating ring. Form.

Embodiment 4 As shown in FIG. 4, in a rotary ring 6 constructed in the same manner as in Embodiment 1, silicone rubber is applied to the lower surface of the flange 9 of the link fixing section 4 that is fitted and placed on the ring rail 1. The formed annular vibration absorbing member 1ot is disposed, and furthermore, a recess at sr having an upper surface that substantially coincides with the lower surface of the vibration absorbing member 10 described above is disposed on the outer surface of the ring fixing portion 4 that fits into the ring rail S. A rotary ring is formed by disposing a circular m-shaped vibration absorbing member 14t made of silicone rubber and having an outer diameter slightly larger than the inner diameter of the ring fitting hole in the recess 1111.

Similarly, the sliding movement in the thrust direction in the above embodiment is larger than that of the sliding surface in the first embodiment.

By the way, in each of the above embodiments, reference numeral 16 is a set spring, which is used to softly fix the rotary ring 6 and the link rail ridge. In addition, the wire diameter of the set spring 16 is 0.1-0.6.
m phosphor bronze wire or hard steel wire tube with an outer diameter of 1. Wrap the tightly coiled spring and Ll so that they are b to low f and both 11i! The springs are connected to each other to form a ring-shaped spring, and are provided so as to extend by approximately a teal with respect to the free length and be tightened.

In addition, in each of the above-mentioned streams, the body 8 of the ring rotating body 1
The height h of the sliding surface of the sliding portion that receives the radial force formed between the outer cylindrical surface of and the inner circumferential surface of the link fixing portion 4 is:
The rotation ring 6 is formed so as to have a total H of ~%.

In addition, the ring fixing part is formed using a 4ri 47 fluoroethylene resin pipe, but it is also possible to use an alloy with J11 abrasion resistance and a low shore friction coefficient pipe, a material obtained by coating gold maple with the above alloy or 47 fluoroethylene resin, or aluminum laminated resin. It is also possible to form a porous type alumite film on an aluminum alloy or by using a material such as a material in which the fine pores of the alumite film are impregnated with molybdenum disulfide by an electrochemical method.

Further, although silicone rubber was used as the vibration absorbing member 10, 12, and 14, a rubber-like elastic member such as a rubber-like elastic material having a Shore hardness of 5f-TO'' plain can also be used.

The rotating ring for a spinning machine according to the present invention is formed so that the height of the sliding movement that receives the force in the radial direction in the sliding part is ~% of the total height of the rotating ring, as described above, so that the clearance of the sliding part is Even if the ring is large, floating during spinning is extremely reduced and stable rotation of the ring can be maintained.

Therefore, the spindle can be rotated at high speed, and high production can be achieved, and high-quality yarn with less yarn breakage and yarn fuzz can be produced.

In addition, a vibration absorbing member tube is placed in the part where the rotating ring is attached to the link rail. Since this is absorbed, the bearing reaction force at each sliding portion is stabilized and does not become excessive. Therefore,
The rotating part rotates extremely smoothly and maintains stable rotation by gently changing the rotation only due to fluctuations in the spinning force of one spinning unit.By stabilizing the rotation of the rotating unit, fluctuations in the spinning force are controlled by the rotating part. It is absorbed by the rotation of the thread and becomes smaller, greatly reducing thread breakage, making it easier to splice one thread, and improving operability.

In addition, if the rotation of the rotating part (b) is stabilized, the running posture of the traveler suspended on the ring 7 lunge will be stabilized, and the yarn fuzz will be greatly reduced, and the yarn quality will also be greatly improved by increasing the yarn strength. Furthermore, it has many effects such as stabilizing the bearing reaction force of the sliding part, preventing real wear of the sliding part, and greatly extending the life of the rotating ring. be.
