[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-6 This utility model provides an embodiment of a plastic oil slider, including a bearing structure 9, which is a sheet-like or columnar structure. A plastic oil 11 is provided on the outside of the bearing structure 9. The plastic oil 11 has arc-shaped structures 10 on both sides and conical structures at the top and bottom. The arc-shaped structures cooperate with rollers 2. The cross-sectional area of ​​the upper end of the conical structure is larger than the cross-sectional area of ​​the lower end or smaller than the cross-sectional area of ​​the lower end. More preferably, the conical structure with the cross-sectional area of ​​the upper end is larger than the cross-sectional area of ​​the lower end can play a locking role. A first protrusion 7 is provided at each end of the bearing structure 9. The plastic oil 11 fits into the bearing structure 9 through injection molding or compression molding process. It should be noted that in some embodiments, the support structure is not limited to the above-mentioned support structure, and a plastic oil slider made of plastic oil can be used directly without the use of a support structure. It should be further noted that the material of the load-bearing structure 9 is not limited, and is not limited to materials such as metals, non-metals, and ceramics. Furthermore, the shape of the load-bearing structure 9 is not limited to the sheet-like or columnar structures mentioned above.

[0020] This utility model also provides a bearing with a plastic body oil slider, including an inner ring 1, a plurality of rollers 2 are provided on the outer surface of the inner ring 1, an outer ring 3 is provided on the outer side of each of the plurality of rollers 2, a pressure ring 4 is snapped on the upper and lower ends of the outer surface of the inner ring 1, a plurality of mounting holes 5 are provided on the upper end face of each of the two pressure rings 4, and a plastic body oil slider 6 is snapped on the opposite side of each of the plurality of rollers 2. Multiple rollers 2 are each fixedly provided with a second protrusion 8 at both the upper and lower ends.

[0021] Specifically, the main structure of the device during use is an inner ring 1, which serves as the core structure for bearing rotation and supports the cylindrical rollers 2. An outer ring 3 is fitted around the outer side of the multiple rollers 2. The inner wall of the outer ring 3 also has raceways that match the rollers 2, allowing the rollers 2 to run stably inside and preventing tilting during operation. Pressure rings 4 are respectively snapped onto the upper and lower ends of the outer surface of the inner ring 1. The upper ends of the two pressure rings 4 are provided with through mounting holes 5. During use, the mounting holes 5 of the pressure rings 4 can engage with the second protrusions 8 at the upper and lower ends of the rollers 2, allowing the pressure rings 4 to constrain the rollers 2 and maintain the relative stability of the multiple rollers 2 during operation. When the rollers 2 are in use, an independent plastic oil slider 6 is snapped onto each adjacent opposite side. The upper and lower ends of the plastic oil slider 6 are fixed with first protrusions 7, which are also snapped onto the rollers 2 during use. The mounting hole 5 corresponding to the pressure ring 4 ensures the stability of the plastic oil slider 6 during use. Each plastic oil slider 6 is composed of a bearing structure and a plastic oil with lubricating function. The plastic oil uses solid plastic oil as the base material. The plastic oil can slowly release lubricating substances through frictional heat during bearing operation, achieving a continuous and stable self-lubricating effect. In order to optimize the fluidity and coverage of the lubricant in the contact area and reduce frictional resistance, the plastic oil is designed with a smooth arc structure on both sides. This arc surface can fit well with the rolling surface of the roller 2, so that the lubricating substances released by the plastic oil slider 6 can quickly cover the surface of the roller 2 during operation. When the plastic oil in the plastic oil slider 6 can no longer provide lubricating substances, the pressure ring 4 can be removed and the plastic oil slider 6 can be replaced. If some sliders are worn, the worn sliders can be replaced.

[0022] Reference Figures 1-6 Two pressure rings 4 are set on the upper and lower parts of multiple rollers 2. The inner ring 1 is made of high carbon chromium bearing steel, the outer ring 3 is made of carburized steel, the multiple rollers 2 are all made of high temperature bearing steel, and the two pressure rings 4 are made of low carbon steel.

[0023] Specifically, the pressure rings 4 are positioned above and below the rollers 2 during use, ensuring the rollers 2 remain stable between the outer ring 3 and the inner ring 1. The inner ring 1 is made of high-carbon chromium bearing steel to ensure high hardness, high wear resistance, and good fatigue life, allowing it to be used for a longer period. The outer ring 3 is made of carburized steel, and its surface is treated with carburizing heat treatment to achieve high hardness and wear resistance, while maintaining sufficient toughness and impact resistance in the core, ensuring strong hardness on the outer surface of the bearing during use. The rollers 2 are all made of high-temperature bearing steel, allowing them to meet the requirements for hardness, dimensional stability, and fatigue resistance when operating at high temperatures. The two pressure rings 4, which position and maintain the position of the rollers 2, are made of low-carbon steel, providing both good machinability and sufficient strength.

[0024] Working principle: When assembling the device, the inner ring 1 needs to be placed inside the outer ring 3 first, and then the roller 2 is placed between the outer ring 3 and the inner ring 1. The inner ring 1, as the core structure of the bearing rotation, can support the cylindrical roller 2. The inner ring 1 is made of high carbon chromium bearing steel to ensure that the inner ring 1 has high hardness, high wear resistance and good fatigue life, so that the inner ring 1 can be used for a long time. The outer ring 3 is made of carburized steel. The outer ring 3 is made of carburized heat treatment process to make its surface have high hardness and wear resistance, while the core maintains sufficient toughness and impact resistance, so that the outer surface of the bearing can have strong hardness when it is used. Pressure rings 4 are respectively snapped onto the upper and lower ends of the outer surface of the inner ring 1. The upper ends of the two pressure rings 4 are provided with through mounting holes 5. When in use, the mounting holes 5 of the pressure rings 4 can be snapped onto the second protrusions 8 at the upper and lower ends of the rollers 2, so that the pressure rings 4 can constrain the rollers 2 and keep the position of multiple rollers 2 relatively stable during operation. When the rollers 2 are in use, an independent plastic oil slider 6 is snapped onto each adjacent opposite side. Each plastic oil slider 6 is composed of a bearing structure and a plastic oil with lubrication function. The plastic oil uses solid plastic oil as the base material. The plastic oil can slowly release lubricating substances through frictional heat during the operation of the bearing, so that the bearing can achieve a continuous and stable self-lubricating effect.

[0025] The plastic oil mentioned in this utility model can be the plastic oil produced by Shanghai Lianyi Bearing Technology Co., Ltd., such as the solid lubricant mentioned in application number 202311206539.8; the plastic oil used in a self-lubricating maintenance-free axle bearing of plastic oil in application number 202422476983.8; and the plastic oil mentioned in a rolling bearing cage of plastic oil in application number 202420524706.7.
