Description

Technical Field

[0001] The utility model relates to the technical field of roller bearings, in particular to a thrust spherical roller bearing which is easy to recycle and reuse. Background Art

[0002] Spherical roller bearings have double-row rollers, a common spherical raceway on the outer ring, and two raceways on the inner ring that are tilted at an angle relative to the bearing axis. Thrust spherical roller bearings are similar to spherical roller bearings in that the raceway surface of the raceway is a spherical surface centered on a point that coincides with the center axis of the bearing. The rollers of this type of bearing are spherical, so they have an automatic self-aligning function. They are used in the aerospace field, as well as in the machine tool, metallurgy, automotive and medical industries.

[0003] The Chinese patent with publication number CN207864423U discloses a thrust spherical roller bearing, which includes: a seat ring, a shaft ring, a roller, a cage and a washer, wherein: the cage is arranged between the seat ring and the shaft ring; the roller is embedded in the cage; the washer is attached to the surface of the small rib of the shaft ring; the sum of the heights of the washer and the shaft ring is equal to the height of the shaft matching surface of the equipment in which the thrust spherical roller bearing is installed. When the equipment in which the thrust spherical roller bearing is installed is modified, the size of the shaft is lengthened. In this application, the sum of the heights of the shaft ring and the washer matches the size of the modified shaft, so that the matching surfaces of the two are matched, and there is no need to redesign and produce new bearings, which saves time and effort, saves a lot of tooling, and reduces processing costs.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: when in use, the above-mentioned device realizes the rotation effect of the bearing by directly placing the rollers inside the seat ring for rotation, but in actual use, multiple groups of rollers often have different wear during the rotation process, and once the wear degree of one roller reaches the threshold side, the entire bearing cannot continue to be used. However, the above-mentioned device is not convenient for replacing new concealed rollers, so there is a waste of unworn parts. Utility Model Content

[0030] A top support groove 10 is provided on the cone part 3; a blocking member 9 is provided on the end of the rotating shaft 5 away from the roller 6, and the side of the blocking member 9 is in contact with the side of the top support groove 10; a spring 11 is provided on the bottom of the inner wall of the top support groove 10; an arc-shaped support member 12 is provided on the top of the spring 11; the side of the arc-shaped support member 12 is rotatably connected to the rotating shaft 5; a rotatably connected pressing ring 13 is provided on the top of the top support groove 10; a through groove 15 is provided on the pressing ring 13; a fixing member 14 is provided on the top of the pressing ring 13; the fixing member 14 is threadedly connected to the pressing ring 13, and the fixing member 14 passes through the pressing ring 13 and is threadedly connected to the top of the cone part 3; the pressing ring 13 is used to limit the pressing of the blocking member 9, and the spring 11 and the arc-shaped support member 12 are used to support the rotating shaft 5.

[0031] A threaded hole is provided on the conical member 3 , the locking member 8 is threadedly connected to the locking ring 7 and the conical member 3 at the same time, and the fixing member 14 is threadedly connected to the pressing ring 13 and the conical member 3 at the same time.

[0032] The width of the bottom supporting groove 4 is greater than the diameter of the rotating shaft 5 , and the width of the top supporting groove 10 is the same as that of the bottom supporting groove 4 .

[0033] A sliding protrusion is provided on the side surface of the arc-shaped support member 12, and a sliding groove is provided on the side surface of the top support groove 10, and the sliding groove is slidably connected to the sliding protrusion.

[0034] An arc-shaped groove is provided on the top of the arc-shaped support member 12 , and a wear-resistant layer is provided on the arc-shaped groove.

[0035] A wear-resistant layer is provided on the side surface of the conical sleeve 2 , and the wear-resistant layer contacts the side surface of the roller 6 .

[0036] The width of the through groove 15 is the same as that of the top supporting groove 10 , and there is a distance between the top of the blocking member 9 and the through groove 15 .

[0037] In this embodiment, the efficiency of bearing maintenance and replacement or parts recycling and reuse can be effectively improved through this device. Compared with traditional devices, this device is easy to disassemble and decompose, and can effectively improve the efficiency of parts replacement, avoiding the waste of unworn parts.

[0038] When the device is in working condition, the structural combination of the bottom plate 102 and the mounting bracket 103 can effectively improve the installation and fixing efficiency of the device, avoiding problems such as misalignment of the device during use. The structure of the conical sleeve 2 can ensure that the conical part 3 is in full contact with the structure of the wrapping part 1 such as the outer shell 101, avoiding problems such as center deviation of the conical part 3 of the device during rotation. The rotational support effect of the conical sleeve 2 on the side of the drum 6 makes the conical part 3 of the device evenly stressed.

[0039] When the roller 6 of the device is worn, the locking member 8 can be rotated in the opposite direction to disengage the locking ring 7 from the top of the bottom supporting groove 4 of the cone 3, and the fixing member 14 can be rotated in the opposite direction to disengage the pressing ring 13 from the top supporting groove 10. The locking member 8 and the fixing member 14 can be unlocked to open the tops of the bottom supporting groove 4 and the top supporting groove 10, so that the staff can take out the rotating shaft 5 and the roller 6 from the inside of the groove and replace the worn roller 6 separately. By placing new roller 6 and rotating shaft 5 parts in the groove, the maintenance and replacement effect of the device is achieved. When there are many worn parts of the roller 6, the intact roller 6 parts that have not been worn can be taken out by unlocking, so as to facilitate recycling and reuse.

[0040] When the device is in high-speed rotation, since the thrust spherical roller bearing has a better axial weighing effect, there may be an axial pressure environment when the device is used. When the device is subjected to axial pressure, the cover plate 104 is slightly deformed under the extrusion, so that the tapered sleeve 2 is squeezed downward, resulting in extrusion between the tapered sleeve 2 and the roller 6. At this time, the structure of the spring 11 and the arc-shaped support member 12 can achieve the effect of tilting and elastically supporting the rotating shaft 5 of the device, so that the rotating shaft 5 can be prevented from being deformed when the pressing force suddenly changes, thereby preventing the roller 6 from shaking when rotating.
