Description

Bearings for Dyeing Machines {Bearing for dyeing machine}

The present invention relates to an underwater bearing for a dyeing machine, and more particularly, in an underwater bearing for smooth rotation of a guide roller that is installed in a dyeing tank and performs fabric transfer, improving wear resistance and reducing noise and frictional force of the underwater bearing. The present invention relates to an improvement of an underwater bearing for a dyeing machine.

In general, the dyeing machine is a kind of post-process for expressing a variety of colors on the woven fabric, in order to perform such dyeing is carried out through various components and work processes.

In the dyeing machine configured to perform such a dyeing operation, a salt bath containing a salt solution for determining the color of the fabric is provided, and a plurality of guide rollers are disposed in the salt bath to smoothly supply and discharge the fabric.

As described above, the guide roller interposed inside the salt bath represents a continuous rotation state at a predetermined speed, and various types of rotation are formed between the guide roller rotation shaft and the salt bath phase in order to facilitate smooth rotation of the guide roller in the continuous rotation state. An auxiliary means is interposed.

As described above, a representative element is a rotational auxiliary means for smooth rotation of the guide roller, but a carbon housing using carbon having strong corrosion resistance and low surface friction coefficient was initially used due to the strong oxidation resistance of the bearing or salt solution.

However, the carbon housing has a low surface friction coefficient, but wear resistance is weak, and the inner diameter is expanded even in a short use time, so that the carbon housing has a disadvantage that the expensive carbon housing must be frequently replaced.

Thus, in order to solve the problem of the carbon housing, as shown in Utility Model Priority Registration No. 0278901, it has come to produce a submerged bearing having a high corrosion resistance stainless material and wear resistance.

Such underwater bearings have a donut-shaped left and right support plate 10 having a shaft insertion opening 11 formed thereon at a predetermined interval as shown in FIG. 1,

Rolling rollers 20 rotatably coupled around the side support plate 10,

A hinge shaft (not shown) fitted to the roller roller 20 to couple the left and right support plates 10 and the roller roller 20 to each other;

The hinge shaft has a rotational space penetrating through the roller roller 20 than the diameter of the hinge shaft to penetrate the roller roller 20 and all the components are made of stainless steel resistant to salt.

The underwater bearing configured as described above is interposed in the housing 7 formed inside the salt bath by fixing the rotary shaft 5 'of the guide roller 5 through the shaft insertion hole 11, and guides the fabric during the dyeing operation. Smooth rotation of the rollers 5 was achieved, and these submerged bearings produced much economic benefits with superior durability compared to carbon housings due to corrosion resistance and abrasion resistance to salt solution.

However, the above-mentioned underwater bearing has the disadvantage that it is extremely difficult to achieve the desired purpose due to the following problems.

① Direct coupling structure of rolling roller (20) and guide roller (5 ') through shaft insertion hole (11).

The underwater bearing 1 maintains a state in which the rotary shaft 5 'of the guide roller 5 is in contact with the inside of the roller roller 20 through the shaft insertion hole 11 without a separate inner ring, in which case the roller roller 20 ) And guide rollers (5) are all made of the same material of stainless steel, which acts as a cause of noise as well as severe wear phenomenon during friction due to continuous rotation.

In particular, when the roller roller 20 is worn out due to the friction of the same material, the problem is solved by replacing the underwater bearing, but when the rotating shaft 5 'of the guide roller 5 is worn out, the entire guide is reversed. There was a big problem to replace the roller (5) had a disadvantage of lowering workability and increasing economic expenditure.

② Wear phenomenon due to friction between the side support plate (10) and the guide roller (5) circumferential surface.

When the submerged bearing is fitted to the rotary shaft housing 7 formed in the salt bath, the left and right support plates 10 positioned in the axial direction maintain contact with one circumferential surface of the guide roller 5 together with the inner wall of the rotary shaft housing 7. .

In this state, when the guide roller 5 rotates, one side of the left and right support plates 10 and the circumferential surface of the guide roller 5 are rubbed, which causes noise and also promotes wear. Abrasion caused inefficient replacement.

③ Operation noise and abrasion according to the rotational space of rolling roller and hinge shaft.

The underwater bearing uses a hinge shaft penetrating the roller roller 20 as a means for fixing the left and right support plate 10 and the roller roller 20, such a roller roller 20 between the hinge shaft for smooth rotation It forms a rotating space, which is a certain space.

The rotational space as described above causes friction between the rolling bearing 20 and the hinge shaft when a load occurs in a direction perpendicular to the axis when the underwater bearing is installed, thereby causing excessive noise during rotation of the guide roller, as well as promoting wear by friction. It acted as a cause of reducing the durability of rolling bearings and reducing the durability of the whole underwater bearing.

In order to solve the above problems, the present invention is designed to accommodate the rotating shaft of the guide roller and further include a thrust washer of the synthetic resin to the inner ring and the bearing support ring interposed in the rolling bearing, thereby improving the wear resistance of the guide roller. It aims at maximizing economic profits by extending the replacement cycle according to the increase of durability of underwater bearings and guide rollers by reducing the noise and operating noise.

The housing 20 is cylindrical and further includes a locking jaw 21 having a diameter slightly smaller than that of the entire inner diameter in order to prevent detachment of the bearing assembly 30 on one side.

The bearing assembly 30 accommodated in the housing 20,

The overall shape is a doughnut-shaped circumferential surface formed a plurality of through-holes 31 at equal intervals, bearing support ring 33 which is interposed a predetermined distance through the fixing pin hole 32 and the fixing pin 32,

The bearing 35 is interposed between the bearing support ring 33, the bearing 35 is formed integrally with the rotating shaft 34 of the diameter corresponding to the through-hole 31 of the bearing support ring 33 in the circumferential shape;

A hollow body having a predetermined diameter has a locking end portion 36 provided with a fastening hole 38 on one side, and consists of an inner ring 37 to be connected to the bearing 35 through an outer circumference.

In addition, the present invention underwater bearing (2) is further provided with a thrust (40) of the synthetic resin material to the bearing support ring (33) outward, the inner side opposite to the engaging end (36) bearing support ring (33) at the edge And a snap ring 39 that is a fixing means for preventing separation of the thrust washer 40 and the like.

Underwater bearing (2) of the present invention configured as described above can be implemented as in other embodiments a fastening structure between the bearing 35 and the bearing support ring 33, as shown in FIG.

To this end, a plurality of fastening protrusions 50 having a predetermined diameter and height are formed on the circumferential surface of the bearing support ring 33 at equal intervals, and the bearing 35 has a recessed groove corresponding to the fastening protrusion 50. 51).

At this time, the fixing pin 32 for mutual fixing of the bearing support ring 33 also forms a coupling structure by the fastening protrusion 50 and the recessed groove 51 to form parts and assemble by the unity with the bearing 35. We aim at ease.

Underwater bearing (2) for a dyeing machine of the present invention configured as described above,

The housing is interposed on one side of the salt bath, and as shown in FIG. 5 through the bearing assembly 30 to facilitate the engagement of the inner ring 37 and the rotary shaft 5 'with the guide roller, and then the bearing assembly 30 is the rotary shaft 5'. In order to prevent the deviation from the ()) through the fastening hole 38 formed in the locking end portion 36 to maintain the fixed state with the rotating shaft (5 ') by the bolt.

As described above, the submerged bearing 2 interposed on the rotating shaft 5 'of the guide roller 5 facilitates the smooth rotation of the guide roller 5 for supplying the fabric to the salt bath together with the driving of the dyeing machine. As for the bearing 2, the inner ring 37 which accommodates the rotating shaft 5 'and the bearing 35 rotate rotationally.

Thus, the guide roller 5 can prevent abrasion of the rotating shaft 5 'by friction with the bearing 35 even under continuous rotation, and the driving of the rotating shaft 5' through the inner ring 37 is a conventional underwater bearing. In this case, the rotating shaft and the bearing form a direct fastening structure, which can solve problems such as deterioration of durability by promoting wear.
