[Structure] A ring made of molten steel and equipped with multiple oil supply ports. A groove with a width of 10 to 100 μm and a depth of 1 to 3 μm is provided on the inner circumferential surface in a direction approximately perpendicular to the traveling direction of the traveler. It is characterized by a total surface area of 10-35%.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to an oil supply ring for spinning machines used for spinning and twisting yarn. .

0002

[Conventional technology]

Conventionally, oil rings for spinning machines were formed by turning using iron-based sintered material as the material. It is formed by carburizing and quenching as a surface hardening treatment and by turning using low carbon steel. Carburizing and quenching is applied as a surface hardening process, and a lubricating hole is provided on the inner circumferential surface of the ring. There is.

0003 However, with the conventional sintered ring mentioned above, the lubrication effect between the ring and the traveler is poor. Although it is possible to rotate at high speed, since it uses sintered material, it has low wear resistance and has a short lifespan. There is a problem of short length, and rings made by turning low carbon steel have high wear resistance. However, it is easy to run out of oil on the inner peripheral surface, and the traveler gets burnt and cannot rotate at high speed. There was a problem.

0004

[Problem that the idea aims to solve]

Therefore, in order to solve the above problems, the present invention was developed in view of the problems of the conventional technology. The purpose is to prevent oil from running out even in high-speed rotation ranges. In addition to providing stable operation, the ring has excellent wear resistance, long ring life, and trouble-free operation. To provide an oil supply ring for a spinning machine with less wear on the bellows.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the spinning machine oiling ring of the present invention is made of molten steel. At least a ring with multiple refueling ports is in contact with the traveler. A groove with a width of 10 to 100 μm and a depth of 1 to 3 μm is provided on the inner peripheral surface of the ring, and the entire area occupied by the groove is This oil supply ring for a spinning machine is characterized by having a surface area of 10 to 35%.

[0006] The width of the groove is preferably 10 to 100 μm; if it is less than 10 μm, it will be difficult for oil to stop. If it exceeds 100μm, the ring surface will become very uneven and the traveler will have trouble running. . The depth of the groove should be 1 to 3 μm; if it is less than 1 μm, it will be difficult for oil to stop; Exceeding this increases the cost of machining the grooves.

[0007] The ratio of the groove to the surface area should be 10 to 35%, and if it is less than 10%, the oil will stop flowing. If it exceeds 35%, the ring surface will become uneven. It gets so big that it makes the traveler's running difficult.

[0008]

[Effect]

Since the spinning machine oiling ring of the present invention has the above structure, water leaks from multiple oiling holes. The oil that oozes out is stretched out by the traveler and forms an oil film on the sliding surface.

[0009] In addition, even when the traveler speed increases, the above grooves are provided so that oil can stay in the grooves. This prevents the oil film from becoming thinner, making it less likely that the oil film will break.

【Example】

Hereinafter, one embodiment of the oil supply ring for a spinning machine of the present invention will be described. Cut into a specified ring shape using S15CK material, with 3 oil supply holes on the inner circumferential surface. 1, carburizing and quenching was performed. Next, the barrel was polished and the lathe marks were removed. Then, polishing marks were made on the inner peripheral surface of the ring in the perpendicular direction using a #600 SiC polishing cloth. By surface machining the surface of the ring obtained by the above method, the convex portions can be removed. It is removed by polishing, and grooves 2 as shown in Figs. 3 was formed.

[0011] Note that the above grooves can be formed by mechanical processing such as polishing or grinding, or by electrical energy such as laser or plasma. It can also be processed using gi.

0012 In addition, as a comparative example, a sintered ring (comparative product B) manufactured by a normal method and a An oil supply ring (comparative product C) without grooves was also manufactured.

[0013] A spinning test was conducted under the following conditions using ring A for spinning machines of the present invention obtained by the above method. Measure and compare the spindle rotation speed, traveler wear amount, and ring wear amount. did.

[0014] test conditions Thread: Acrylic Nm32/2 Ring: 11.1mm height φ85.0mm Ring Traveler: SBA No. 18 Spindle rotation speed: 7000r.p.m ~ 12000r.p.m Ring oil: KS160

[0015] FIG. 3 shows the wear amount of the traveler when operating under the above spinning conditions. The amount of wear on the traveler of this product A is small even during high-speed operation, and it has good lubricity. However, comparison product C runs out of oil during high-speed operation, and the amount of traveler wear decreases. Increase rapidly.

[0016] Next, Fig. 4 shows the spindle speed at 10,000 hours under the spindle rotation speed of 8,000 r.p.m. Indicates the amount of wear on the ring after long periods of operation. Traveler wear is relatively low even during high-speed operation Comparative product B, which had less wear, also had more ring wear. In addition, Comparative Product C ran out of oil, resulting in significantly increased ring wear.

[0017]

[Effect of the idea]

Since the present invention is constructed as described above, the lubricity of the ring is improved and it also has wear resistance. Because of its high durability, the traveler does not burn out and the ring life can be greatly extended. This is an idea that has practical effects.
