Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a tungsten-nickel alloy bearing which is easy to disassemble. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Under a certain load, the number of revolutions or hours that a bearing experiences before pitting corrosion occurs is called the bearing life. Bearings can be divided into sliding bearings, spherical plain bearings, rolling bearings, deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, etc. Bearings are generally used in conjunction with shafts.

[0003] However, the existing bearing inner ring and outer ring are integrated structures. When the inner ring or outer ring of the bearing is damaged, it is difficult to disassemble the inner ring and outer ring of the bearing because the balls inside the bearing support the inner ring and outer ring, which is not conducive to the maintenance, inspection or replacement of the inner ring or outer ring of the bearing. Therefore, it does not meet the existing needs. In this regard, we propose a tungsten-nickel alloy bearing that is easy to disassemble. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figures 1 to 4 As shown, a tungsten-nickel alloy bearing that is easy to disassemble includes a bearing metal outer ring 1 and a bearing metal inner ring 2. The outer surface of the bearing metal inner ring 2 is provided with a splicing groove 8, and a splicing block 5 is slidably engaged with the inner side of the splicing groove 8. The outer surface of the splicing block 5 is provided with a docking slot 7. The inner side of the splicing slot 8 is provided with two symmetrically distributed anti-offset slots 9. The depth of the anti-offset slots 9 is one-fourth of the thickness of the bearing metal inner ring 2. Positioning end blocks 6 are fixed at both ends of the docking slot 7, and the positioning end blocks 6 are engaged with the inner side of the anti-offset slot 9. The integrity of the bearing is ensured by clamping the splicing block 5 on the inner side of the splicing groove 8 without affecting the normal use of the bearing. After the splicing block 5 is removed from the splicing groove 8, an open gap is formed at the splicing groove 8, and the bearing balls 3 can be easily removed from the splicing groove 8. After all the bearing balls 3 between the bearing metal outer ring 1 and the bearing metal inner ring 2 are removed, the bearing metal outer ring 1 and the bearing metal inner ring 2 can be easily disassembled, which is convenient for the maintenance, inspection or replacement of the bearing metal outer ring 1 and the bearing metal inner ring 2.

[0021] The outer surface of the bearing metal inner ring 2 and the inner surface of the bearing metal outer ring 1 are both provided with ball retaining grooves 4. A plurality of bearing balls 3 are installed between the bearing metal outer ring 1 and the bearing metal inner ring 2. The bearing balls 3 are clamped between the two ball retaining grooves 4 and distributed in a circular array around the axis of the bearing metal outer ring 1. The ball retaining grooves 4 provide rolling support for the bearing metal outer ring 1 and the bearing metal inner ring 2, ensuring that the bearing metal outer ring 1 and the bearing metal inner ring 2 can rotate freely without interfering with each other.

[0022] The docking slot 7 and the ball slot 4 on the outer surface of the bearing metal inner ring 2 are spliced together to form a complete annular groove, ensuring that the bearing ball 3 rolls smoothly in the ball slot 4 and the docking slot 7 on the outer surface of the bearing metal inner ring 2, and there will be no depressions or protrusions at the connection between the ball slot 4 and the docking slot 7, which will not adversely affect the rolling of the bearing ball 3.

[0023] A protrusion is provided on the side of the positioning end block 6 facing the splicing block 5. The positioning end block 6 is fixed to the splicing block 5 through the protrusion and there is a gap between the positioning end block 6 and the splicing block 5. A V-shaped groove 10 is provided on the inner side of the end of the positioning end block 6 that is clamped in the anti-slip groove 9. Anti-slip pads 11 are bonded to the upper and lower surfaces of the positioning end block 6. The gap between the positioning end block 6 and the splicing block 5 enables the upper and lower surfaces of the positioning end block 6 to be elastically deformed due to the presence of the V-shaped groove 10 when squeezed, thereby reducing the difficulty of operation when installing the positioning end block 6.

[0024] The outer surface of the anti-slip gasket 11 is kept flush with the outer surface of the positioning end block 6. The anti-slip gasket 11 is made of rubber. The anti-slip gasket 11 increases the contact friction between the positioning end block 6 and the inner surface of the anti-slip slot 9 after the positioning end block 6 is installed inside the anti-slip slot 9, ensuring that the positioning end block 6 will not detach from the inside of the anti-slip slot 9 without human intervention.

[0025] Working principle: When assembling the bearing metal outer ring 1, the bearing metal inner ring 2 and the bearing balls 3, it is only necessary to place the bearing metal inner ring 2 on the inner side of the bearing metal outer ring 1, and then clamp the bearing balls 3 between the bearing metal outer ring 1 and the bearing metal inner ring 2 from the splicing groove 8, and then rotate the bearing metal inner ring 2 or the bearing metal outer ring 1 so that the installed bearing balls 3 are misaligned with the splicing groove 8, and repeat the installation operation of the bearing balls 3 to install all the bearing balls 3 between the bearing metal outer ring 1 and the bearing metal inner ring 2. After the bearing balls 3 are installed, slide the splicing block 5 on the inner side of the splicing groove 8, and ensure that the positioning end blocks 6 at both ends of the splicing block 5 are clamped on the inner sides of the two anti-off grooves 9. The anti-slip gaskets 11 on the surface of the positioning end block 6 increase the contact friction between the positioning end block 6 and the inner surface of the anti-off groove 9, ensuring that after the splicing block 5 is installed, the splicing block 5 will not move along the axial direction of the bearing metal outer ring 1 without external force interference. The inner side of the splicing groove 8 falls off to ensure the structural stability of the bearing after assembly. When the metal outer ring 1 or the metal inner ring 2 of the bearing is damaged and needs to be replaced, it is only necessary to remove the splicing block 5 from the inner side of the splicing groove 8, so that a gap is formed on the outer surface of the metal inner ring 2 of the bearing at the splicing groove 8. Then, the metal outer ring 1 or the metal inner ring 2 of the bearing is rotated so that the splicing groove 8 is rotated to the position of the bearing ball 3. Due to the existence of the splicing groove 8, the distance between the metal outer ring 1 and the metal inner ring 2 of the bearing is increased. After the bearing ball 3 reaches the splicing groove 8, the bearing ball 3 detaches from between the two ball clamping grooves 4 and falls from between the metal outer ring 1 and the metal inner ring 2 of the bearing. According to the above-mentioned operation of removing the bearing ball 3, all the bearing balls 3 are removed from between the metal outer ring 1 and the metal inner ring 2 of the bearing, reducing the difficulty of disassembling the metal outer ring 1 and the metal inner ring 2, shortening the operation time, and improving the efficiency of bearing inspection, maintenance or replacement of parts.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
