[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-Figure 6 A single-row roller bearing shown includes an outer ring 1, an inner ring 2, a retaining frame 3 and a roller 4. The outer ring 1, the inner ring 2 and the retaining frame 3 are coaxially arranged, and the roller 4 is arranged in plurality, and the plurality of rollers 4 are all arranged on the retaining frame 3. This arrangement is a conventional arrangement, so it is not described in detail.

[0021] In order to solve the problem that the single-row roller bearing in the technology is inconvenient to disassemble and assemble, once the bearing is damaged, it is generally replaced as a whole, resulting in a waste of resources. The utility model arranges the retaining frame 3 between the outer ring 1 and the inner ring 2. The retaining frame 3 includes a base frame 5, a roller frame 6, a bolt 7, a nut 8, a washer 9 and a cover plate 10. The roller frame 6, the bolt 7 and the nut 8 are all arranged in multiple numbers. The multiple roller frames 6 are evenly distributed on the base frame 5, and one end of the roller frame 6 is fixedly connected to the base frame 5, and the other ends of the multiple roller frames 6 are fixedly connected to the bolt 7. The bolt 7 is threadedly connected to the nut 8. The washer 9 is sleeved on the bolt 7 and arranged at the bottom of the nut 8. The cover plate 10 is arranged above the bolt 7. When installing the bearing, the base frame 5 is first clamped on the outer ring 1, since one end of the rolling frame 6 is fixed on the base frame 5, the rolling frame 6 is inside the outer ring 1, and a plurality of vertical grooves are formed between the base frame 5, the rolling frame 6 and the outer ring 1, and then one side of the plurality of rollers 4 is placed in the plurality of vertical grooves, and then the washers 9 are sleeved on the bolts 7, and a plurality of nuts 8 are installed on the bolts 7 to complete the fixation, and the cover plates 10 are covered on the bolts 7 to protect the nuts 8, and finally the inner ring 2 is clamped between the plurality of rollers 4. When the rollers 4 are damaged and need to be replaced, it is only necessary to pull out the cover plates 10, remove the nuts 8, and remove the washers 9 to remove the damaged rollers 4, and then take out the new rollers 4 and install them back. The disassembly and assembly are convenient, and only the damaged rollers 4 need to be replaced, and there is no need to replace the entire roller, which can save resources.

[0022] It should be noted that the number of bolts 7 and nuts 8 can be set according to the actual requirements of the bearing, as long as the bearing can be fixed, so there is no limitation.

[0023] The base frame 5 and the cover plate 10 are both stuck inside the outer ring 1 and are respectively located on both sides of the inner part of the outer ring 1. The setting of the cover plate 10 can protect the nut 8 and the internal roller 4, can reduce the dust entering the inner part of the bearing, and can better protect the bearing.

[0024] The washer 9 is provided with a plurality of circular holes which are evenly distributed on the washer 9 , and the bolts 7 are inserted into the circular holes.

[0025] An inclined groove 11 is provided on the side of the cover plate 10 away from the bolt 7, and the inclined groove 11 does not penetrate the cover plate 10. The setting of the inclined groove 11 is convenient for removing the cover plate 10. Because the inclined groove 11 does not penetrate the cover plate 10, dust will not enter the bearing from the inclined groove 11.

[0026] The outer ring 1 is provided with a plurality of through holes 12, and the plurality of through holes 12 are evenly distributed on the side of the outer ring 1, and long bolts can be inserted into the plurality of through holes 12 to fix the bearing in a desired position, which can ensure stability and facilitate disassembly and assembly.
