Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to low-friction rolling bearings. Background Technology

[0002] The main function of bearings is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearings are mainly classified into sliding bearings, spherical plain bearings, deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings, flange bearings, and linear bearings. Among these, rolling bearings are one of the most commonly used types. Rolling bearings are precision mechanical components that convert the sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing frictional losses.

[0003] The current publication number CN207131733U discloses a rolling bearing, including an inner ring with an inner raceway on its outer surface in the radial direction; an outer ring with an outer raceway on its inner surface in the radial direction; and a plurality of rolling elements arranged between the outer surface of the inner ring and the inner surface of the outer ring, wherein the inner raceway or the outer raceway is in partial contact with the rolling elements.

[0004] To address the issue of reducing friction, existing technologies employ multiple rolling elements. However, this approach still presents the problem of cumbersome lubrication processes, which in turn leads to increased wear and reduced service life. Utility Model Content

A handle is fixedly connected to the surface of the oil injection pipe, and the surface of the oil injection pipe is threaded. An oil outlet hole is opened inside the oil injection pipe, and a T-shaped rod is slidably connected inside the oil injection pipe. A spring is fixedly connected to one side of the T-shaped rod, and a sealing block is fixedly connected to one end of the spring. One side of the sealing block is fixedly connected to one end of the T-shaped rod.

[0012] A further improvement of the present invention is that the flow unit includes an outer circle, which is slidably connected to the surface of the ball, and a recessed hole is provided inside the outer circle.

[0013] By adopting the above technical solution, the anti-leakage unit is designed to be recessed by the recessed hole inside the outer circle, so as not to affect the use of the main body of the device.

[0014] A further improvement of this utility model is that: an oil flow channel is provided inside the outer circle, and a connecting channel is connected inside the oil flow channel.

[0017] By adopting the above technical solution, the dustproof plate effectively blocks external dust, while the wear-resistant sealing block one and wear-resistant sealing block two further enhance the sealing effect of the dustproof plate and reduce oil leakage.

[0018] A further improvement of this utility model is that: a T-shaped rod is slidably connected inside the dustproof plate, one end of the T-shaped rod is slidably connected inside the positioning hole, and a spring is fixedly connected to one side of the T-shaped rod, one end of the spring being fixedly connected inside the dustproof plate.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1.

[0021] 2. This utility model provides a low-friction rolling bearing. The recessed hole inside the outer circumference allows the anti-leakage unit to be recessed, thus not affecting the use of the main body of the device. The oil flow channels and connecting channels ensure even oil distribution among the parts during oiling. The dustproof plate effectively blocks external dust. The wear-resistant sealing blocks one and two further enhance the sealing effect of the dustproof plate, reducing oil leakage. The wear-resistant sealing block two and T-shaped rod one facilitate the disassembly of the dustproof plate for cleaning and maintenance. Attached Figure Description

A dustproof unit 2 is provided on the outer side of the inner circle 1, and a leak-proof unit 3 is provided on one side of the inner circle 1. The leak-proof unit 3 includes an oil injection pipe 31, which is located on one side of the inner circle 1. A handle 32 is fixedly connected to the surface of the oil injection pipe 31, and a thread 33 is provided on the surface of the oil injection pipe 31. An oil outlet hole 34 is opened inside the oil injection pipe 31, and a T-shaped rod 35 is slidably connected inside the oil injection pipe 31. A spring 36 is fixedly connected to one side of the T-shaped rod 35, and a sealing block 37 is fixedly connected to one end of the spring 36. A sealing block 37 is fixedly connected to one side of the sealing block 37. Connecting to one end of the T-shaped rod 35, the oil injection pipe 31 is screwed into the recessed hole 162 through the thread 33. At the same time, the oil injection gun is placed inside the oil injection pipe 31, and the sealing block 37 is pushed to slide inside the oil injection pipe 31. Simultaneously, the T-shaped rod 35 is pushed to slide under the limit of the oil injection pipe 31, and the sealing block 37 is moved to the bottom side of the oil outlet hole 34. At the same time, the lubricating oil is pumped into the oil passage 163 through the oil outlet hole 34. After the oil injection is completed, the sealing block 37 at one end of the T-shaped rod 35 is driven back to the initial position by the elastic action of the spring 36, thereby achieving a seal and reducing the occurrence of oil leakage.

[0025] Example 2 like Figure 1-5 As shown, based on Embodiment 1, the present invention provides the following technical solution: Preferably, the flow unit 16 includes an outer circle 161, which is slidably connected to the surface of the ball 12. A recessed hole 162 is provided inside the outer circle 161, and an oil flow channel 163 is provided inside the outer circle 161. A connecting channel 164 is connected inside the oil flow channel 163. Lubricating oil flows through the oil flow channel 163 inside the outer circle 161. At the same time, the lubricating oil is applied to the surface of the ball 12 through the connecting channel 164, thereby reducing the friction between the ball 12 and the inner circle 1 and the outer circle 161, and further improving the service life.

[0026] Example 3 like Figure 1-5As shown, based on Embodiment 1, this utility model provides the following technical solution: Preferably, the inner circle 1 includes a positioning hole 11, which is formed on the surface of the inner circle 1. A ball bearing 12 is slidably connected to the inner side of the inner circle 1, and a retainer 13 is rotatably connected to the surface of the ball bearing 12. An annular concave plate 14 is fixedly connected to the surface of the inner circle 1. A flow unit 16 is slidably connected to one side of the ball bearing 12, and an annular concave plate 25 is provided on one side of the flow unit 16. The dustproof unit 2 includes a dustproof plate 21, which is disposed on one side of the inner circle 1. A wear-resistant sealing block 22 is fixedly connected to the bottom surface of the dustproof plate 21, and a wear-resistant sealing block 23 is fixedly connected to the bottom surface of the dustproof plate 21. A T-shaped rod is slidably connected inside the dustproof plate 21. One end of the T-shaped rod 24 is slidably connected to the inside of the positioning hole 11. A spring 25 is fixedly connected to one side of the T-shaped rod 24. One end of the spring 25 is fixedly connected to the inside of the dustproof plate 21. By pulling the T-shaped rod 24, the spring 25 is extended, and the dustproof plate 21 is placed on one side of the inner circle 1. At the same time, the wear-resistant sealing block 22 contacts the inner side of the annular concave plate 15, and the wear-resistant sealing block 23 contacts the inner side of the annular concave plate 14. The T-shaped rod 24 is placed inside the positioning hole 11. Then, the elastic action of the spring 25 completes the fixation of the dustproof plate 21, thereby achieving the sealing work. At the same time, the positioning of the ball 12 is maintained by the setting of the retainer 13.

[0027] The working principle of this low-friction rolling bearing will be explained in detail below.

[0028] like Figure 1-5As shown, by pulling the T-shaped rod 24, the spring 25 is extended, and the dustproof plate 21 is placed on one side of the inner circle 1. At the same time, the wear-resistant sealing block 22 contacts the inner side of the annular concave plate 15, and the wear-resistant sealing block 23 contacts the inner side of the annular concave plate 14. The T-shaped rod 24 is placed inside the positioning hole 11. Then, the elastic action of the spring 25 completes the fixation of the dustproof plate 21, thereby achieving the sealing work. At the same time, the positioning of the ball 12 is maintained by the setting of the retainer 13. The oil injection pipe 31 is screwed into the recessed hole 162 through the thread 33. At the same time, the oil injection gun is placed inside the oil injection pipe 31, and the sealing block 37 is pushed in the oil injection pipe 31. The internal sliding of the T-shaped rod 35, under the limit of the oil injection pipe 31, drives the sealing block 37 to slide to the bottom side of the oil outlet 34, and pumps the lubricating oil through the oil outlet 34 into the oil flow channel 163. After the oil injection is completed, the elastic action of the spring 36 drives the sealing block 37 at one end of the T-shaped rod 35 back to the initial position, thereby achieving a seal and reducing oil leakage. At the same time, the lubricating oil flows through the oil flow channel 163 inside the outer circle 161, and the lubricating oil is applied to the surface of the ball 12 through the connecting channel 164, which reduces the friction between the ball 12 and the inner circle 1 and the outer circle 161, further improving the service life.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
