[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3 The present invention provides an embodiment of a device for ensuring stable rotation, comprising an outer ring 1 and an inner ring 2, with a plurality of balls 4 arranged between the outer ring 1 and the inner ring 2. The outer ring 1 serves as an external support structure of the device and cooperates with the inner ring 2 to provide a running track for the balls 4. A lubrication component is arranged inside the outer ring 1, and lubrication can effectively reduce friction, making the rotation of the device smoother and more stable. A wear-resistant component is arranged inside the balls 4, and the wear-resistant component can improve the wear resistance of the balls 4.

[0032] Reference Figure 1-Figure 3 The lubrication assembly includes multiple oil chambers 6, which are opened inside the outer ring 1. The oil chamber 6 is used as a space for storing lubricating oil. It is set inside the outer ring 1 to make full use of the internal space of the outer ring 1. A sliding rod 7 is slidably connected to the oil chamber 6. The sliding rod 7 can slide up and down in the oil chamber 6 to control and transport the lubricating oil. Two baffles 8 are fixedly connected to the outside of the sliding rod 7. The baffles 8 can limit the moving range of the sliding rod 7. The baffles 8 can also prevent the lubricating oil from leaking from the gap between the sliding rod 7 and the inner wall of the oil chamber 6. A spring 10 is fixedly connected to the upper side of the sliding rod 7. The spring 10 is used to provide elastic force when resetting. An oil-absorbing sponge 11 is fixedly connected to the bottom of the sliding rod 7. The oil-absorbing sponge 11 evenly applies the lubricating oil to the outside of the ball 4. An oil outlet 9 is opened at the bottom of the sliding rod 7. The oil outlet 9 can make the lubricating oil in the oil chamber 6 flow smoothly to the oil-absorbing sponge 11.

[0033] Reference Figure 3The wear-resistant component includes a bead core 12, which is installed inside the ball 4. As the core part of the ball 4, the bead core 12 bears the main load and rotation functions. A protective layer 13 is provided on the outside of the bead core 12. The protective layer 13 can protect the bead core 12 from the influence of the external environment. A wear-resistant layer 14 is fixedly connected to the outside of the protective layer 13. The wear-resistant layer 14 has extremely high wear resistance and can withstand friction and wear when the ball 4 contacts the outer ring 1 and the inner ring 2.

[0034] Reference Figure 1-Figure 3 There are multiple sealing bolts 5 threadedly connected to the upper side of the outer ring 1. The sealing bolts 5 can seal the lubrication components inside the outer ring 1 to prevent lubricating oil leakage. The number of sealing bolts 5 and oil chambers 6 is equal and evenly distributed on the outside of the outer ring 1, ensuring that each oil chamber 6 can be effectively sealed, thereby improving the reliability and stability of the device.

[0035] Reference Figure 1-Figure 3 The bottom of the baffle 8 fits in with the inner wall of the outer ring 1, and the baffle 8 can prevent the lubricating oil from leaking out of the oil chamber 6. The side of the oil-absorbing sponge 11 away from the slide rod 7 fits in with the outer side of the ball 4, ensuring that the lubricating oil can be evenly applied to the outer side of the ball 4.

[0036] Reference Figure 1 A stabilizing frame 3 is installed between the outer sides of multiple balls 4. The stabilizing frame 3 can fix the balls 4 in a certain position to prevent the balls 4 from deviating or falling off during the rotation process.

[0037] Reference Figure 4 The bead core 12 is made of GCr15 bearing steel. GCr15 bearing steel has high hardness, high wear resistance and high elastic limit. It can withstand large loads and impacts to ensure the strength and stability of the ball 4. The protective layer 13 is made of zirconia ceramic. Zirconia ceramic has the characteristics of high strength, high hardness, high temperature resistance, corrosion resistance and low friction coefficient. It can protect the bead core 12 from the influence of the external environment. The wear-resistant layer 14 is made of polytetrafluoroethylene. Polytetrafluoroethylene has the characteristics of extremely low friction coefficient, good lubricity and corrosion resistance. It can reduce friction and wear when the ball 4 contacts the outer ring 1 and the inner ring 2, thereby improving the rotation performance of the ball 4.

[0038] Reference Figure 1 The number of balls 4 in the oil chamber is 6, and they are evenly distributed inside the stable frame 3, ensuring that each ball 4 can be fully lubricated.

[0039] Reference Figure 3 The end of the spring 10 away from the slide rod 7 is fixedly connected to the inner wall of the outer ring 1. The spring 10 can provide a certain elastic force for the slide rod 7, so that the oil-absorbing sponge 11 is always in close contact with the outer side of the ball 4.

[0040] Working principle: During the rotation of the bearing, the inner ring 2 will rotate, further driving the ball 4 to rotate. At the same time, the outer ring 1 will rotate through the ball 4. When the ball 4 rotates to the side of the oil-absorbing sponge 11 away from the slide bar 7, the slide bar 7 will slide. The sliding of the slide bar 7 drives the baffle 8 to slide and squeezes the oil outlet 9. When the baffle 8 slides, the lubricating liquid inside the oil chamber 6 will pass through the oil outlet 9 and adhere to the upper side of the oil-absorbing sponge 11, and further smear the surface of the ball 4 through the oil-absorbing sponge 11, thereby reducing the wear of the ball 4 during rotation and increasing the service life of the bearing.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
