Description

[Detailed description of the invention] This invention is a conical type ring, a vertical ring, etc. (hereinafter referred to as a vertical ring) used for spinning cotton, worsted, synthetic fibers, etc., and for stretching, twisting, and plying yarns or filaments. This invention relates to the structure of an oil-supplied rotating ring for a passive drive type spinning machine that provides extremely smooth rotation.

Conventionally, the rotation mechanism of a passive drive type rotating ring has been considered to be one in which ball bearings are placed around the outer circumference of the ring, but since the ring itself is thin and has a large diameter, it is difficult to obtain a perfect circle, so the rotational resistance of the ball bearing is This has disadvantages, such as the inconsistency and instability, which can lead to thread breakage, and the fact that fluff adheres to the ball bearing, hindering rotation, causing thread breakage and traveler burn.

The present invention solves the above-mentioned drawbacks, and provides an oil-supplied rotary ring for a spinning machine, which allows the oil supply ring to be converted into a rotary ring by integrally incorporating an oil supply device into the rotary ring.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

As shown in the drawing, a concave oil supply groove 2 is provided around the entire circumference of the holder ring body 1 , and the upper end of the inner peripheral wall 3 of the oil supply groove is subjected to wear-resistant, low-friction nitriding treatment or soft nitriding treatment. An annular sliding member 4 made of steel or a low-friction wear-resistant synthetic resin such as polyamide, polyacetal, Teflon, etc. is press-fitted and fixed. On this sliding member 4, a sliding ring 5 made of high-carbon steel material that has been hardened by heat treatment and subjected to high-precision grinding to a required roundness of 0.05 mm or less is rotatably fitted. A vertical oil supply ring 6 is press-fitted into the inner circumference of the ring, and a retaining ring 7 is attached to the outer circumference to prevent the sliding ring from coming off. Furthermore, an annular lid 9 is fitted to the upper end of the outer peripheral wall 8 of the oil supply groove 3 and fixed to a part of the holder with screws, covering the retaining ring attached to the sliding ring, and covering the inner peripheral part thereof. Bring them into contact and lightly press the retaining ring to form a cover for the oil supply groove.

Further, a fuel tank 10 is integrally provided on the peripheral edge of the holder ring adjacent to the outer peripheral wall of the oil groove of the holder ring, and a communication hole 11 that communicates with the oil groove is provided in the outer peripheral wall of the oil groove. Further, the upper surface of the oil supply tank is covered with a cover plate 12 having an oil supply hole to constitute an oil supply type rotary ring for a spinning machine.

The oil guide thread 13 of the vertical ring has one end hanging down into the oil supply groove 2 of the holder ring body through the oil guide thread hole 14 provided in the sliding ring 5, and the oil supply groove is supplied with oil from the oil supply tank 10. This is done through the hole 11.

In the oil-supplied rotary ring for a spinning machine of the present invention, the vertical ring 6 and the sliding ring 5 slide and rotate together on the sliding member 4 as a unit due to the rotational force generated by the contact between the traveler and the vertical ring during spinning, At this time, the end of the oil guide thread is immersed in the oil supplied to the oil supply groove 2 while supplying oil to the vertical ring.

Further, the sliding portion is supplied with the amount of oil necessary for lubrication by raising the oil level or scattering the oil in the oil supply groove due to the stirring action of the oil guiding thread. In addition, the sliding ring and sliding member are combined in a convex-concave relationship, reducing the load in the thrust direction and radial direction.
The gap between these is preferably 0.05 to 0.1 mm.

Since the present invention has the above structure, the frictional resistance between the sliding ring and the sliding member is extremely low, the rotation of the vertical ring is extremely smooth, the occurrence of thread breakage is extremely low, and the ring can be smoothly rotated. As it rotates, the relative speed between the ring and the traveler decreases,
Furthermore, the automatic lubrication system eliminates traveler burn, allowing high-speed spindle rotation and large packages.

Furthermore, by press-fitting the vertical ring into the sliding ring, it is possible to improve the roundness, equalize the sliding resistance, and help smooth the rotation of the ring.

Furthermore, it is a device that has excellent effects such as simultaneous oil supply to the vertical ring and the sliding part with a simple structure and ease of handling.
