Description

[Detailed description of the invention] This invention relates to an improvement of an oil supply ring for a spinning machine.
The purpose is to stably supply lubricating oil over a long period of time to the inner peripheral surface of the ring, which is the main part of the ring that the traveler rubs against.

Conventionally, 0.6rr was applied to the inner peripheral surface of the ring that rubbed on the traveler.
A pore of about 7 mφ to 1.5r11/IT1φ is provided, and an oil supply body having a capillary action such as a thread is buried in the pore,
There was an oil supply ring that had one end of the oil supply body aligned with the ring surface vC, and the other end of which was brought into contact with an oil guiding body that went around the outer periphery of the control ring and communicated with the oil storage tank.

This type of lubrication ring was generally used in a wide range of fields, including spinning and twisting of long fibers such as worsted and woolen fibers, and plied and twisted yarns of synthetic fibers. However, there were disadvantages in that the amount of oil immersed in each ring varied and was not uniform over time.

In addition, two oil supply holes that are continuous with the oil supply groove provided on the outer circumference of the ring are provided on the inner circumferential surface of the ring, and two oil supply holes are provided on the inner circumferential surface of the ring to connect the two oil grooves. There is a ring that has grooves with an angle of This has the disadvantage that it disturbs the running posture of the machine, induces thread breakage, and causes abnormal wear of the ring and traveler.

In addition, since the width and depth of the groove are approximately the same as the diameter of the oil supply hole, the oil supply body inserted through the oil supply hole protrudes from the groove, and the oil supply body is configured to completely prevent depression. Therefore, when the traveler comes into contact with the protruding oil supply body, there is a drawback that the oil supply body is cut, making spinning impossible, or causing abnormal sliding of the traveler.

The present invention has been developed in order to eliminate the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings.

Embodiment As shown in FIGS. 2 and 3, in a ring 1 having oil guide grooves 2 circumferentially carved on the outer circumferential surface, one diagonal groove 3 or equally spaced diagonal grooves 3 are formed on the inner circumferential surface of the ring 1. Form multiple pieces.

The diagonal groove 3 has a groove width a of 1.0 to 1.5 m/m, a groove length b of 6 to 7 of the groove width a, and a groove depth gh of about 6/l of the groove width a.
0 to 7/10 and the angle α with respect to a line perpendicular to the axis of the ring and a line parallel to it has a value of 5° to 100.

In addition, the bottom surface of the oblique groove 3 is composed of a single curve, and the radius varies depending on the length and depth of the groove, but the diameter is 13φ to 20φ.
Form using a cutter.

Furthermore, the bottom surface of the oblique groove 3 has a hole diameter of 0.65 to 0 of the groove width a.
．． 75, and the oil guiding groove 2 provided on the outer peripheral surface of the ring.
Two oil supply thread holes 4 are bored through the.

Note that the intervals C between the oil supply thread holes 4 are 3 to 5 m/m, and they are arranged at equal positions in the length direction of one groove.

Moreover, the distance d between the center of the oil supply thread hole located on the upper side of the ring and the top surface of the ring among the two upwardly raised oil supply thread holes 4 is 5.
0 to 7.0 m/m.

In the above embodiment, three diagonal grooves 3 are arranged at equal intervals around the entire circumference of the ring, as shown in FIG. It is also possible to provide

In addition, as shown in FIG. 1A and FIG. Approximately the same number of diagonal grooves 3 are bored.

The vertical hole 5 is not located at the same position as the oblique groove 3,
In the case of one, they are arranged at opposing positions, and in the case of a plurality of them, they are arranged at equal intervals so as to be located approximately midway between the diagonal grooves 3.

In the ring 1 formed as described above, the oil supply thread (not shown) is guided from the oil guide groove 2 to the inner peripheral surface of the ring through one of the oil supply thread holes 4, guided inside the diagonal groove 3, and guided through the oil supply thread hole. 4, the oil is drawn out again to the oil guide groove 2, goes around inside the oil guide groove 2, and is guided to the next oil supply thread hole 4 and diagonal groove 3.

In this way, the oil supply thread is connected to the oil guide groove 2, the oil supply thread hole 4, and the diagonal groove 3.
are inserted in sequence and go around the ring to form an oil supply body.

Here, the oil supply thread disposed in the diagonal groove 3 is disposed at a position where its surface is substantially the same as or slightly protrudes from the inner circumferential surface of the ring.

In addition, separate oil supply threads are inserted through the vertical holes 5, and their ends on the ring top surface side are positioned so as to be substantially flush with the ring top surface, and the other ends are guided into the oil guide grooves 2. ing.

Furthermore, an oil guide thread is disposed to circulate within the oil guide groove 2 so as to be in contact with each of the oil supply threads, thereby forming an oil supply ring.

The end of the oil guiding thread is guided into the oil tank of the ring holder, which stores lubricating oil.

In the oil supply ring with the above configuration, the groove width of the diagonal groove 3 is 1.0
m If it is smaller than 7 m, the thickness of the oil supply thread guided there will be thin, and the supply of lubricating oil necessary during spinning will be insufficient, causing traveler burn.

On the other hand, if t is larger than 5 m/m, the amount of lubricating oil supplied becomes too large, causing thread staining and contamination of the machine stand, and also causing the traveler to get caught in the corners of the diagonal groove, causing thread breakage.

The depth of the groove was set to approximately 6/10 to 7/lO of the groove width, but 7/10
If it is larger than 10, the oil supply line will sink into the diagonal groove,
If the lubrication performance is lower than 6/10, the lubricating thread will protrude too much from the inner circumferential surface of the ring, causing the lubricating thread to be cut or broken due to sliding of the traveler.

The angle of the diagonal groove was set between 5° and 100, but if it is smaller than 5°, the lubrication performance will be significantly reduced and the wear resistance of the ring will deteriorate rapidly. This causes thread breakage and abnormal wear of the ring, shortening its lifespan.

Further, an explanation will be given based on spinning data showing the influence of the angle of the oblique grooves on the wear rate or life of the traveler.

BAA group SB factory 28 As a result of spinning under the above spinning conditions, as shown in Figure 5, if the angle of the diagonal groove is less than 5 degrees, it is A,
B In both cases, the wear rate of the ring increases rapidly,
If the angle exceeds 10°, the wear rate will gradually increase,
In either case, the performance of the ring is unsatisfactory.

Since the oil supply ring for spinning machines according to the present invention has the above configuration,
The OT dragon eliminates the possibility of the oil supply thread sinking from the ring surface or being cut due to the sliding friction of the traveler, and provides stable lubricating oil supply for an extremely long period of time.

In addition, when the traveler slides, the phenomenon of the traveler getting caught on the side corners of the groove and causing abnormal wear of the ring does not occur at all, and furthermore, the abnormal sliding of the traveler is eliminated.
Not only the lifespan of the ring, but also the lifespan of the traveler can be greatly extended.

Furthermore, it has many practical effects, such as being able to reliably supply oil to the portion of the inner peripheral surface of the ring that comes into contact with the traveler.
