Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bearing for crankshaft or connecting rod, especially relates to a rod end joint bearing with good lubricating effect. BACKGROUND

[0002] The rod end joint bearing is a key component widely used in mechanical transmission, automobile suspension, aerospace and industrial equipment, and its main function is to connect and transmit motion and force, while allowing rotation or swing within a certain range.

[0003] The traditional lubricating method of the rod end joint bearing is mostly periodic smearing or injecting lubricating oil, which is difficult to ensure that the lubricating oil continuously and stably plays a role in the bearing working process. When the equipment is continuously running, the lubricating oil is quickly consumed, causing local wear of the bearing to intensify, shortening its service life. Moreover, frequent shutdown for maintenance not only reduces production efficiency but also increases maintenance cost. Therefore, the rod end joint bearing with good lubricating effect is proposed. SUMMARY

[0004] The utility model discloses a rod end joint bearing with good lubricating effect, which can solve the problem that the traditional lubricating method of the rod end joint bearing is mostly periodic smearing or injecting lubricating oil, which is difficult to ensure that the lubricating oil continuously and stably plays a role in the bearing working process. When the equipment is continuously running, the lubricating oil is quickly consumed, causing local wear of the bearing to intensify, shortening its service life. Moreover, frequent shutdown for maintenance not only reduces production efficiency but also increases maintenance cost.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a rod end joint bearing with good lubricating effect, comprising:

[0006] The bearing outer ring, threaded rod end and bearing inner ring are provided. The bearing inner ring is installed inside the bearing outer ring, the threaded rod end is welded at the bottom of the bearing outer ring, a plurality of rolling grooves are formed on the outer surface of the bearing inner ring, and a plurality of rolling columns are rolling connected inside the rolling grooves.

[0007] The bearing lubricating structure is located on the bearing outer ring.

[0008] The bearing lubrication structure includes multiple lubrication rollers and oil-absorbing cotton. An oil reservoir is provided inside the outer ring of the bearing. An installation through groove is provided on the inner bottom wall of the oil reservoir, which is connected to the inside of the outer ring of the bearing. An oil injection hole is provided on the outer surface of the outer ring of the bearing, which is connected to the inside of the oil reservoir. Multiple rotating grooves are provided on both sides of the inner wall of the installation through groove. Rotating rods are rotatably connected inside the multiple rotating grooves. Multiple lubrication rollers are fixedly connected to the opposite faces of two corresponding rotating rods. Multiple lubrication rollers are rotatably connected inside the installation through groove. Oil-absorbing cotton is fixedly installed on the inner bottom wall of the oil reservoir.

[0009] Preferably, the bearing lubrication structure further includes a sealing bolt, which is threaded into the oil injection hole.

[0010] Preferably, there are two sealing rings that slide between the outer ring and the inner ring of the bearing.

[0011] Preferably, the outer surfaces of both sealing rings are slidably connected to the interior of the bearing outer ring, and the inner walls of both sealing rings are slidably connected to the outer surface of the bearing inner ring.

[0012] Preferably, the outer surfaces of the plurality of lubrication rollers are in contact with the oil-absorbing cotton.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This rod end joint bearing with good lubrication effect utilizes a unique structure composed of an oil reservoir, oil-absorbing cotton, and lubrication rollers. Since the lubricating oil does not directly penetrate between the three lubrication rollers, the rotation of the lubrication roller 11 allows the lubricating oil to act evenly and continuously on the friction surface of the roller 6. Compared with the traditional method of periodically applying or injecting lubricating oil, this greatly reduces the consumption rate of lubricating oil, avoids local wear caused by rapid depletion of lubricating oil, and effectively extends the service life of the bearing.

Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a rod end joint bearing with good lubrication effect, comprising:

[0027] The bearing consists of an outer ring 1, a threaded rod end 2, and an inner ring 3. The inner ring 3 is installed inside the outer ring 1. The threaded rod end 2 is welded to the bottom of the outer ring 1. Multiple rolling grooves 7 are formed on the outer surface of the inner ring 3, and rollers 6 are rolled inside the multiple rolling grooves 7.

[0028] The bearing lubrication structure is located on the outer ring 1 of the bearing.

[0029] The bearing lubrication structure includes multiple lubrication rollers 11 and oil-absorbing cotton 9. An oil storage groove 8 is provided inside the outer ring 1 of the bearing. An installation through groove 13 is provided on the inner bottom wall of the oil storage groove 8. The installation through groove 13 communicates with the interior of the outer ring 1 of the bearing. An oil injection hole 12 communicating with the interior of the oil storage groove 8 is provided on the outer surface of the outer ring 1 of the bearing. Multiple rotating grooves 14 are provided on both sides of the inner wall of the installation through groove 13. Rotating rods 10 are rotatably connected inside the multiple rotating grooves 14. Multiple lubrication rollers 11 are fixedly connected in the opposite face of two corresponding rotating rods 10. Multiple lubrication rollers 11 are rotatably connected inside the installation through groove 13. Oil-absorbing cotton 9 is fixedly installed on the inner bottom wall of the oil storage groove 8. The outer surface of multiple lubrication rollers 11 is in contact with oil-absorbing cotton 9.

[0030] The bearing lubrication structure also includes a sealing bolt 4, which is threaded into the oil injection hole 12.

[0031] There are two sealing rings 5 ​​that are slidably connected between the outer ring 1 and the inner ring 3 of the bearing. The outer surfaces of the two sealing rings 5 ​​are slidably connected to the inside of the outer ring 1, and the inner walls of the two sealing rings 5 ​​are slidably connected to the outer surface of the inner ring 3.

[0032] Furthermore, when using this device, before the bearing is properly lubricated, the lubricating oil is injected into the oil reservoir 8 through the oil injection hole 12 by unscrewing the sealing bolt 4 on the oil injection hole 12. The oil-absorbing cotton 9 at the bottom of the oil reservoir can quickly absorb and store the lubricating oil. Then, the sealing bolt 4 is screwed back on to prevent lubricating oil leakage and external impurities from entering the oil reservoir. When the rod end spherical bearing is working, the inner ring 3 of the bearing rotates relative to the outer ring 1 of the bearing, driving the roller 6 to roll in the rolling groove 7. At the same time, the lubricating roller 11 installed in the mounting groove 13 rotates due to contact with the roller 6. Since the outer surface of the lubricating roller 11 is in contact with the oil-absorbing cotton 9, during the rotation, the lubricating roller will absorb the lubricating oil from the oil-absorbing cotton and apply it to the contact surface of the roller 6 to achieve uniform and continuous lubrication.

[0033] This invention utilizes a unique structure consisting of an oil reservoir 8, oil-absorbing cotton 9, and a lubricating roller 11. Since lubricating oil does not directly permeate between the three lubricating rollers 11, the rotation of the lubricating rollers 11 allows the lubricating oil to act evenly and continuously on the friction surface of the roller 6. Compared with the traditional method of periodically applying or injecting lubricating oil, this greatly reduces the consumption rate of lubricating oil, avoids local wear caused by rapid depletion of lubricating oil, and effectively extends the service life of the bearing.

[0034] Structural Description: Bearing Outer Ring 1: Provides external support for the bearing inner ring and related components. It has an oil reservoir and mounting groove inside to accommodate the lubrication structure and cooperates with the bearing inner ring to achieve relative rotation.

[0035] Threaded rod end 2: Welded to the bottom of the outer ring of the bearing, used to easily install the bearing onto various mechanical parts to achieve the connection and operation of the equipment;

[0036] Inner ring 3 of the bearing: It is installed inside the outer ring of the bearing. Rolling grooves are opened on the outer surface to cooperate with the rollers and achieve relative rotation with the outer ring of the bearing. It is a key component for transmitting motion and load.

[0037] Sealing bolt 4: Threaded connection inside the oil filling hole. It is opened when filling oil and tightened after filling oil to prevent lubricating oil leakage and external impurities from entering the oil reservoir.

[0038] Sealing ring 5: Installed between the outer ring and the inner ring of the bearing to prevent lubricating oil leakage, and at the same time to block external dust, impurities and other contaminants from entering the bearing;

[0039] Roller 6: Roller is connected in the rolling groove of the inner ring of the bearing to reduce the friction between the inner and outer rings when they rotate relative to each other, thus ensuring smooth movement.

[0040] Oil reservoir 8: Located inside the outer ring of the bearing, it stores lubricating oil and provides the material basis for the continuous lubrication of the bearing;

[0041] Oil-absorbing cotton 9: It is fixedly installed on the bottom wall of the oil storage tank to absorb and store lubricating oil, while providing a stable oil source for the lubrication roller;

[0042] Rotating rod 10: Rotatably connected in the rotating groove on the inner wall of the mounting through groove, providing support for the lubrication roller and enabling it to rotate within the mounting through groove;

[0043] Lubricating roller 11: Fixedly connected to the rotating rod, it comes into contact with the oil-absorbing cotton to absorb lubricating oil when rotating, and applies the lubricating oil to the contact surface between the inner and outer rings of the bearing to achieve uniform lubrication.
