The present invention relates to the inner ring collar of the self-aligning roller bearing, the outer ring is integrally coupled to the holding annular ring of the bearing body, and the yaw-shaped inner ring is coupled so as to prevent harmful sliding between the rollers through the rolling rollers In the inner ring, a portion of the collar wall of the inner ring is formed to cut, and the block color is formed to be integrally fixed to the notched portion, thereby facilitating the assembly of the rollers between the outer ring and the inner ring of the bearing body. It can withstand the load in the axial direction without difficulty, stabilizes the position of the roller, and also provides the smooth rolling motion in the provision of the inner ring collar of the self-aligning roller bearing.

In forming the collar on the inner ring 20 of the conventional bearing body, as shown in FIG. 6, the rollers are easily assembled in the other collar 40 while integrally molding the collar 30 on one inner ring. In order to make it was made separately so that it can be coupled to the inner ring.

That is, the formation of the other collar is made in the shape of an expanding ring to form a plurality of screw holes on the circumferential side thereof, and further, the fastening holes are formed on the side of the collar engaging portion of the inner ring so as to face the screw holes. The collar 40 is configured to be fastened to the inner ring by fastening mechanisms such as a plurality of bolts 50 and the like.

Accordingly, after assembling the rollers between the outer ring and the inner ring, the annular ring-shaped collar is coupled to the side of the inner ring to be fastened and fixed by bolts 50 one by one to separate and detach the collar 40 from the inner ring 20. However, if the load is applied in the axial direction as the inner ring that is mounted and fixed to the shaft is rotated, the bolts are gradually released to hinder the normal driving of the rollers, and more severely, the bearing itself is lost. It was often the result of doing so.

Also, in the formation of the collar, not only the screw holes are formed on the side of the collar, but also the production efficiency can be increased by increasing the number of processes in which the fastening holes must be formed on the side of the inner ring to which the collar is coupled to face the screw holes. There is a drawback in that the production cost is high due to the fact that precision is required in forming the holes.

The present invention, in order to eliminate the above-mentioned drawbacks, while forming both collars of the inner-shaped inner ring integrally to form a notch groove enough to insert the rolling rollers in one collar, assembling the rollers through this notch groove After the assembly of the rollers is completed, the block collar having the same size as the cut groove is fixed integrally to the notch groove, thereby facilitating the assembly of the rollers and simultaneously bearing the inner ring and the collar by an integral collar. Even if the sieve is subjected to an axial load, the rollers can be smoothly maintained without the collar being separated.

Referring to the configuration of the present invention in detail by the accompanying drawings as follows.

As shown in FIG. 1, the outer annular ring is configured such that the outer ring 2 is integrally coupled to the retaining annular ring 1 having an inner diameter, and the retaining annular ring 1 and the outer ring 2 are formed. In the oil inlet 3 is formed.

In the outer diameter of the outer ring 2, a driving portion 5 capable of driving the rollers 4 to be described later and a collar 6 having a predetermined height are formed on both side surfaces of the driving portion 5.

Next, the inner ring 7 assembled through the rollers 4 in the recess 5 of the outer ring 2 will be described.

The inner ring 7 has a roller drive part 8 formed at a central part thereof, and a ring-shaped collar 9 capable of holding the side surfaces of the rollers 4 which are rolling elements on both sides so as to be in contact with the driving part 8 in an excavated manner. 9a are formed to protrude to a certain height.

One of these collars 9 and 9a is cut out to a width that allows the rollers 4 to be inserted into a portion of the collar 9, and as shown in FIG. 1, the collar notches 10 are formed. The fastening hole 11 is formed in the side wall of this collar notch 10.

Then, the screw notch 13 is passed through the side of the block collar 12 so as to form the same collar as the face of the collar 9a which is closely assembled and opposed to the collar notch 10, and the collar It is manufactured by matching the center of the center so that the fastening hole 11 of the notch groove 10 and the screw hole 13 are connected.

Therefore, in assembling the block collar 12 into the above-mentioned collar cutting grooves 10, the block collar 12 is aligned with the collar cutting grooves 10, and then the high information bolt 14 is fastened to the screw holes 13 and fastened. By being fastened to the hole 11, the completed collar 9 of the inner ring 7 can be formed easily.

That is, according to the present invention, as shown in FIGS. 4 and 5, even if a load is generated in the axial direction by cutting off a part of the collar 9 and integrally compensating the cutout portion with the block collar 12, Since the area of the one-piece collar 9a with the inner ring 7 other than the block collar 12 is large, the position of the rollers 4 may be stabilized and the rollers may be smoothly rolled to receive a strong load. The service life can be extended as compared with the related art.

In the arrangement of the rollers 4 according to the present invention, as shown in FIG. 3, rather long rollers and short rollers are arranged between the outer ring 2 and the inner ring 7 at zigzag equidistant intervals and loaded in the axial direction. And it is arranged in consideration of expansion due to the temperature difference of the bearing body.

Referring to the operation and effects of the present invention is as follows.

As shown in FIG. 1, the rollers 4 are inserted through the collar cutting grooves 10 with the block collar 12 removed from the collar 9 of the inner ring 7 so that the rollers 4 become the outer ring. (2) and the vibration parts 5 and 8 of the inner ring 7 are assembled.

Then, after assembling up to the last rollers 4, the block collar 12 is assembled into the collar cutting groove 10 and bolted to the screw hole 13 and the fastening hole 11 by the high information bolt 14. The fastening of the block collar 12 to the collar 9 is completed simply by tightening.

Accordingly, the block collar 12 is integrated with the collar 9 of the inner ring 7 to guide and hold the rollers 4 between the outer ring 2 and the inner ring 7 to function as one collar element. .

The present invention exhibits a function in which the collar 9, which assembles the block collar 12, is integrally formed with the inner ring 7 and held evenly together with the opposite collar 9a, thereby rotating the inner ring 7, Even if the bearing body is operated under the condition that the outer ring 2 is stopped, it is possible to minimize the occurrence of gaps due to the elastic deformation or expansion due to the temperature difference between the inner ring and the housing, as well as the axial load on the bearing body. Even if this is applied, the rollers 4 can be sufficiently held by the integral collars 9 and 9a of the inner ring 7 tube, so that the collar is loosened from the inner ring as in the prior art and impedes transmission of the rollers. It can be used to prolong its life without worrying about its own loss.

The present invention as described above can be used to extend the service life by applying to continuous casting equipment, steel rolling equipment, paper machines, conveyors, steam, dryers, general industrial machinery and the like.
