2. Description of the Related Art Conventionally, when assembling a full-roller cylindrical roller bearing, it has to be assembled with great care so that the rollers do not fall off from the outer ring raceway, or as shown in FIG. ) 100 to outer ring track 201
The roller 300 is fixed to the track 201 of the outer ring 200 by using the viscosity, and the inner ring is quickly assembled with all the rollers 300 fixed to the outer ring 200 so that the rollers 300 are not dropped. I was

[0003]

However, assembling with great care so that the rollers do not fall off the outer ring raceway as in the prior art, the work is very difficult and requires a high level of skill and skill. It had been. Further, FIG.
Even when assembling using grease (oil) 100 as shown in the above, the grease 10
Because it is only held using a viscosity of 0, quick assembly and careful attention is required so that the rollers do not fall off.

In the case where oil-air lubrication is used for lubricating the bearing, grease cannot be used as shown in FIG.

Although the rollers do not fall off unless the inner ring is removed, it is necessary to reassemble the inner ring at regular inspections without removing the inner ring. The process has to go through the process, and there is a problem that reassembly of the bearing is very troublesome.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to solve the problem of roller falling off without using grease or high-viscosity oil. An object of the present invention is to provide an assembling ring capable of reliably assembling a full roller cylindrical roller bearing.

[0007]

An annular main body formed with an outer diameter slightly smaller than the inscribed circular diameter of a cylindrical roller disposed on an outer raceway, and one point on the circumference of the main body from the upper end. The roller insertion slit is formed with a width of one cylindrical roller over the lower end.

[0008]

According to the above-mentioned technical means, a bearing assembly ring is inserted and arranged inside the outer ring, and is formed at one place on the circumference of the ring body with a width enough to allow one cylindrical roller to pass therethrough. The required number of cylindrical rollers can be sequentially inserted and mounted on the outer raceway from the inner diameter side through the inserted slit.

When the cylindrical roller is inserted, the previously inserted roller is pushed in the circumferential direction between the outer raceway and the outer periphery of the ring to be held, or the ring itself is slid in the circumferential direction. Therefore, the rollers inserted first do not fall off even when the rollers are sequentially inserted.

After all the rollers are mounted on the outer raceway, the inner race is brought into contact with the upper or lower part of the bearing assembly ring, and the bearing assembly ring is slid so as to be pushed out in the axial direction. The bearing can be easily assembled by inserting and replacing the inside of the outer ring.

[0011] The full-roller cylindrical roller bearing assembling ring is
Since the outer diameter is slightly smaller than the diameter of the inscribed circle of the cylindrical roller, the roller can be stably and smoothly fixed to the raceway of the outer ring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a full roller cylindrical roller bearing assembling ring according to the present invention. The bearing assembly ring 1 has an annular body 2 having an outer diameter slightly smaller than the inscribed circle diameter of the cylindrical rollers 8 arranged on the outer ring raceway 7. A roller insertion slit 3 is formed at a location from the upper end 2a to the lower end 2b with a width w of substantially one cylindrical roller (see FIG. 3).

The width (W) of the roller insertion slit 3 is determined in accordance with the shape of the cylindrical roller to be housed, and is set arbitrarily.

The annular body 2 is not particularly limited with respect to its annular height h, and may have any height as compared with the outer ring 4 and has a height capable of holding the cylindrical roller 8. Any configuration is possible within the scope of the present invention. The thickness t is arbitrary.

The material of the annular body 2 is not limited, but if it is made of paper or plastic, the weight is reduced and the handling is improved, and there is no fear of damaging the cylindrical rollers when assembling the bearing. .

Note that the company name, C
I, how to use, etc. may be printed.

Next, a method of assembling a full-roller cylindrical roller bearing using the above-described bearing assembling ring 1 will be described. For example, first, with the several cylindrical rollers 8 set on the raceway 7 of the outer ring 4, the bearing assembling ring 1 is inserted and arranged inside (the inner diameter side) of the outer ring 4 (the imaginary line in FIG. 1). ).

Then, all the remaining cylindrical rollers 8 are inserted one by one into the outer ring raceway 7 from the insertion slits 3 of the bearing assembling ring 1, and are inserted first when the cylindrical rollers 8 are inserted. , The outer ring raceway 7 and the ring outer circumference 2c
To be held between the outer raceway 7 and the outer periphery 2c of the ring by sliding the ring 1 itself in the circumferential direction. The cylindrical rollers 8 do not fall off even when the cylindrical rollers 8 are sequentially inserted (see FIG. 2).

Next, with the cylindrical rollers 8 inserted between the outer ring raceway 7 and the outer circumference 2c of the bearing assembly ring 1 as described above, the collarless inner ring 9 is moved to the bearing assembly ring 1. The inner ring 9 is inserted into the outer ring 4 and replaced by pushing the inner ring 9 so as to push (slide) the bearing assembling ring 1 in the axial direction. The bearing can be assembled (see FIGS. 4 and 5). Further, the inner ring 9 without the collar is provided with the ring 1 for bearing assembly.
The inner ring 9 may be inserted inside the outer ring 4 for replacement by pushing the inner ring 9 so as to push (slide) the bearing assembling ring 1 in the axial direction. Optional.

In the above process, several cylindrical rollers 8 are inserted before the bearing assembly ring 1 is inserted and disposed inside the outer ring 4. After the insertion, the necessary number of all cylindrical rollers 8 may be inserted one by one.

The bearings to which the present invention can be applied are not limited to those shown in the drawings.
All general well-known full-roller cylindrical roller bearings comprising a straight inner ring 9 without a brim and cylindrical rollers 8 arranged between the raceway 7 of the outer ring 4 and the outer periphery 9a of the inner ring 9 are applicable. For example, a guide roller free side bearing of a continuous casting machine, which is mounted on an inner spherical surface portion of a spherical seat ring whose outer diameter is a convex spherical surface and has a concave spherical surface on the inner diameter, is optional.

[0023]

The present invention has a configuration as described above,
Since the required number of cylindrical rollers can be easily and securely and safely held on the outer ring raceway, the cylindrical rollers are fixed (held) on the outer ring raceway by applying lubricating grease or high-viscosity oil as in the past, and the inner ring is quickly mounted in this state It is not necessary to adopt a troublesome and difficult assembling method for assembling, and it is possible to easily assemble a full-roller cylindrical roller bearing without paying much attention and without requiring skill.

Also, even in the case of oil-air lubrication in which grease or high-viscosity oil cannot be used, there is no need to pay close attention to the falling off of the cylindrical rollers as in the conventional case, and no skill is required. It is very useful because it can be assembled.

Further, since the outer diameter of the full roller cylindrical roller bearing assembling ring of the present invention is slightly smaller than the diameter of the inscribed circle of the cylindrical roller, the cylindrical roller is stably and smoothly held on the raceway of the outer ring. Fixed).
