Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and in particular relates to high-sealing bearing rollers. Background Technology

[0002] The core function of bearing rollers is to reduce bearing friction, bear loads, and guide rotational motion. The sliding friction between the shaft and the bearing housing is converted into rolling friction, which greatly reduces motion resistance. At the same time, they transmit radial, axial, or combined loads through their own rolling, disperse pressure to protect the shaft and bearing housing, maintain the rotational accuracy of the shaft, limit radial and axial displacement, and ensure stable motion trajectory.

[0003] Currently, when sealing bearings, most methods involve placing a sealing ring between the inner and outer rings to enclose the internal rollers or balls, preventing dust from entering the bearing and blocking contact between the rollers or balls and the outside environment, thus forming a protective seal. However, after prolonged use, the sealing ring lip may deform or twist, and the seal may become aging, cracked, hardened, or swollen due to high temperatures, oil contamination, or chemical corrosion. This can lead to excessively large gaps between the sealing ring contact surface and the inner and outer rings of the bearing, resulting in a poor seal. Therefore, it is necessary to replace the internal sealing ring and add or replace the internal lubricant.

[0004] Current methods for replacing bearing seals mostly involve using a screwdriver to pry the original seal out from the bearing and then pressing the new seal into the bearing. While this method can replace the seal, it is rather crude. Errors in force and installation angle during pressing can cause friction between the seal and the bearing, resulting in wear and scratches on the seal and reducing its sealing performance. Therefore, we propose high-sealing bearing rollers. Utility Model Content

Grooves 5 are provided on the inner sides of both the inner ring 1 and the outer ring 2. The balls 3 are disposed inside the grooves 5. There are multiple balls 3, and the multiple balls 3 are arranged in a circular array. The cage 4 is disposed outside the balls 3. Both the inner ring 1 and the outer ring 2 have a first sealing groove 6 on their inner sides. The first sealing ring 7 is in contact with the inside of the first sealing groove 6. Both the inner ring 1 and the outer ring 2 have an installation groove 8 on their inner sides. A pressure ring 9 is detachably installed inside the installation groove 8. One side of the pressure ring 9 is in contact with the outer surface of the first sealing ring 7. The first sealing ring 7 acts as a barrier and protector outside the ball 3, preventing external dust from contacting the ball 3 and keeping the ball 3 clean. The pressure ring 9 acts as a barrier outside the first sealing ring 7, maintaining the stability of the first sealing ring 7 and preventing the first sealing ring 7 from moving outward. The pressure ring 9 is fixed inside the installation groove 8 by screws.

[0025] An oil-blocking groove 10 is provided on the inner side of the first sealing ring 7. Multiple protrusions 11 are provided on the inner side of the first sealing ring 7, and the multiple protrusions 11 are arranged in an equidistant array. The protrusions 11 communicate with the oil-blocking groove 10. An oil-blocking ring 12 is fixedly connected to one side of the pressure ring 9. The outer surface of the oil-blocking ring 12 is fixedly connected with the same number of protrusions 13 as the protrusions 11. The outer surface of the oil-blocking ring 12 contacts the inner wall of the oil-blocking groove 10, and the outer surface of the protrusions 13 contacts the inner wall of the protrusions 11.

[0026] The oil blocking groove 10 and the protrusion 11 provide a space for the oil blocking ring 12 and the protrusion 13. After the oil blocking ring 12 and the protrusion 13 are installed inside the oil blocking groove 10 and the protrusion 11, the oil blocking ring 12 and the protrusion 13 form multiple blocking barriers to reduce the probability of lubricating oil leakage to the outside. The oil blocking ring 12 and the protrusion are manufactured as a single piece.

[0027] Example 2: This example provides a high-sealing bearing roller. In addition to the technical solutions of the above examples, it also has the following technical features: the first sealing ring 7 is made of rubber, and a support ring 14 is fixedly connected inside the first sealing ring 7, and the support ring 14 is made of metal.

[0028] The support ring 14 provides support for the first sealing ring 7, giving it a stable supporting force and reducing the likelihood of deformation.

[0029] Example 3: This example provides a high-sealing bearing roller. In addition to the technical solutions of the above examples, it also has the following technical features: a second sealing groove 15 is provided on the inner side of both the inner ring 1 and the outer ring 2. A second sealing ring 16 is fixedly installed on the inner wall of the second sealing groove 15. The outer surface of the second sealing ring 16 is in contact with one side of the pressure ring 9.

[0030] The second sealing ring 16 seals the pressure ring 9, preventing lubricating oil from leaking to the outside through the gap between the pressure ring 9 and the mounting groove 8.

[0031] Example 4: This example provides a high-sealing bearing roller. In addition to the technical solutions of the above examples, it also has the following technical features: a plurality of heat dissipation fins 17 are fixedly connected to the outer surface of the first sealing ring 7, and the plurality of heat dissipation fins 17 are arranged in a circular array.

[0032] The bearing as a whole will generate heat after long-term operation. The heat dissipation fins 17 and the first sealing ring 7 are manufactured as a single unit. The heat dissipation fins 17 release the heat inside the bearing and the first sealing ring 7 to the outside, thereby reducing the heat inside the bearing and the first sealing ring 7.

[0033] Example 5: This example provides a high-sealing bearing roller. In addition to the technical solutions of the above examples, it also has the following technical features: two oil reservoirs 18 are opened on the inner side of the first sealing ring 7, and the two oil reservoirs 18 are symmetrical. One oil reservoir 18 is located on one side of the outer ring 2, and the other oil reservoir 18 is located on one side of the inner ring 1.

[0034] The oil reservoir 18 stores lubricating oil, which lubricates the contact points between the first sealing ring 7 and the inner ring 1 and outer ring 2, reducing wear on the first sealing ring 7 by the inner ring 1 and outer ring 2 and improving the service life of the first sealing ring 7.

[0035] Example 6: This example provides a high-sealing bearing roller. In addition to the technical solutions of the above examples, it also has the following technical features: multiple magnetic blocks 19 are fixedly connected to the outer surface of the cage 4, and the multiple magnetic blocks 19 are arranged in a circular array.

[0036] During operation, the ball bearing 3 will rub against the groove 5 and the cage 4. This friction will cause iron filings to fall off. The magnetic block 19 will attract the falling iron filings, reducing the contact between the iron filings and the ball bearing 3, the cage 4 and the groove 5, thus reducing the friction between them.

[0037] Working principle: When the first sealing ring 7 needs to be replaced, firstly, the screws inside the pressure ring 9 are removed, and then the pressure ring 9 is taken out from the inside of the mounting groove 8, thus releasing the positioning restriction on the first sealing ring 7. Then, lubricating oil is applied to the inside of the oil reservoir 18 inside the new first sealing ring 7, and at the same time, a layer of lubricating oil is applied to the outside of the first sealing ring 7. The lubricating oil reduces the friction between the first sealing ring 7 and the first sealing groove 6 during installation. At the same time, the entire bearing is cleaned to remove the old sludge inside the bearing and the iron filings adsorbed on the magnetic block 19. Then, new lubricating oil is applied into the inside of the bearing. Then, the new first sealing ring 7 is placed into the inside of the first sealing groove 6, and the pressure ring 9 is installed into the inside of the mounting groove 8. At the same time, the oil blocking ring 12 and the protrusion 13 are pushed into the inside of the oil blocking groove 10 and the protrusion 11. Finally, the screws are tightened to fix the pressure ring 9.
