Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a high-pressure-bearing and deformation-resistant bearing ring. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearing rings are annular parts of inner rolling bearings with one or more raceways.

[0003] The current bearing rings are all one-piece annular parts. When the bearing needs to be repaired, the maintenance personnel must disassemble the retaining frame, which is time-consuming and labor-intensive, increases the difficulty of maintenance, and reduces work efficiency. In addition, the current bearing rings are prone to deformation and are inconvenient to use. In this regard, we propose a high-pressure-bearing and deformation-resistant bearing ring to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to provide a bearing ring with high pressure resistance and deformation resistance, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a high pressure-bearing and deformation-resistant bearing ring, comprising:

[0006] A bearing ring body, wherein a raceway ring is arranged inside the bearing ring body, and a locking ring is arranged outside the bearing ring body. The bearing ring body comprises two semicircular rings, a groove is arranged at the outer edge of one side wall of the semicircular ring, a clamping ring is arranged on one side wall of the locking ring, the clamping ring and the locking ring are integrally cast, and two symmetrically arranged grooves are arranged on the outer wall of the clamping ring, and fastening bolts are threadedly connected to the inner thread of the grooves, screw holes are arranged on the grooves of the two semicircular rings, and the fastening bolts are threadedly connected in the screw holes.

[0007] Preferably, four pairs of plug-in rods are arranged on the inner wall of the clamping ring, and two pairs of plug-in grooves are respectively opened on the clamping grooves of the two semicircular ferrules, and the plug-in rods are movably plugged into the plug-in grooves.

[0008] Preferably, a plug hole is provided in the middle of the inner wall of the semicircular ring, and semicircular plug holes are provided on the inner walls at both ends of the semicircular ring.

[0009] Preferably, four limiting columns are fixedly welded on the outer wall of the raceway ring, the four limiting columns are equidistantly distributed in a ring, and the limiting columns are adapted to the insertion holes.

[0010] Preferably, the plug-in rod and the clamping ring are integrally formed.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the utility model is in use, when it is necessary to remove the bearing ring, the two fastening bolts can be unscrewed in turn, the locking ring can be removed, the limit on the bearing ring body can be released, and then the two bearing ring bodies can be removed in turn, thereby realizing quick disassembly of the bearing ring and facilitating the maintenance of the bearing ring, saving time and effort. At the same time, after the raceway ring is worn, only the raceway ring needs to be replaced, and there is no need to replace the entire bearing ring, thus saving resources. The locking ring can be used to reinforce the outside of the bearing ring body, and the raceway ring can be used to reinforce the inside of the bearing ring body, thereby improving the overall pressure-bearing and deformation-resistant performance of the bearing ring.

[0020] A bearing ring body 1 is provided with a raceway ring 2 inside the bearing ring body 1, and a locking ring 3 is provided outside the bearing ring body 1. The bearing ring body 1 includes two semicircular rings 4, and a groove 5 is provided at the outer edge of one side wall of the semicircular ring 4. A clamping ring 6 is provided on one side wall of the locking ring 3. The clamping ring 6 and the locking ring 3 are integrally cast. Two symmetrically arranged grooves 7 are provided on the outer wall of the clamping ring 6, and a fastening bolt 8 is threadedly connected to the inner wall of the groove 7. Screw holes 9 are provided on the grooves 5 of the two semicircular rings 4, and the fastening bolts 8 are threadedly connected in the screw holes.

[0021] Four pairs of plug-in rods 10 are arranged on the inner wall of the clamping ring 6, and two pairs of plug-in grooves 11 are opened on the clamping grooves 5 of the two semicircular rings 4. The plug-in rods 10 are movably plugged into the plug-in grooves 11. Through the plug-in cooperation between the provided plug-in rods 10 and the plug-in grooves 11, the semicircular ring 4 and the locking ring 3 can be limited and fixed to prevent the semicircular ring 4 from rotating in the locking ring 3.

[0022] The semicircular ferrule 4 has an insert hole 12 in the middle of its inner wall, and semicircular insert holes 13 are provided on the inner walls at both ends of the semicircular ferrule 4 . When the two semicircular ferrules 4 are fitted together, the two semicircular insert holes 13 can form a slot body identical to the insert hole 12 .

[0023] Four limiting columns 14 are fixedly welded on the outer wall of the raceway ring 2. The four limiting columns 14 are equidistantly distributed in a ring. The limiting columns 14 are adapted to the insertion holes 12. The raceway ring 2 can be fixed in the bearing ring body 1 by plugging and fitting the limiting columns 14 into the insertion holes 12.

[0024] The plug-in rod 10 and the clamping ring 6 are integrally formed.

[0025] Working principle: When the utility model is in use, when it is necessary to remove the bearing ring, the two fastening bolts 8 can be unscrewed in turn, the locking ring 3 can be removed, the limit on the bearing ring body 1 can be released, and then the two bearing ring bodies 1 can be removed in turn, thereby realizing rapid disassembly of the bearing ring and facilitating the maintenance of the bearing ring, saving time and effort. At the same time, after the raceway ring 3 is worn, only the raceway ring 3 needs to be replaced, and there is no need to replace the entire bearing ring, thus saving resources. The locking ring 3 provided can reinforce the outside of the bearing ring body 1, and the raceway ring 3 provided can reinforce the inside of the bearing ring body 1, thereby improving the overall pressure-bearing and anti-deformation performance of the bearing ring.
