Double-inner-ring bearings are a type of bearing, a special type of bearing. The main purpose of the double-inner-ring structure is to facilitate clearance adjustment. By controlling the axial distance between the two inner rings, the clearance of the bearing can be adjusted to achieve a preload effect. Therefore, it is necessary to design a double-inner-ring deep groove ball bearing.

[0003] Most existing double-half inner ring deep groove ball bearings are manually lubricated through a single oil inlet. Manual lubrication is cumbersome and increases the inconvenience and practicality for operators. Utility Model Content

[0004] The purpose of this invention is to provide a double-half inner ring deep groove ball bearing, which solves the problem of the existing double-half inner ring deep groove ball bearing requiring manual lubrication, which is cumbersome and increases the number of steps for operators.

[0005] To achieve the above objectives, a double-half-inner-ring deep groove ball bearing is provided, comprising an outer ring, bearing needle rollers evenly arranged on both sides inside the outer ring, a cage being provided on the outside of multiple sets of bearing needle rollers, an inner ring being provided on the inside of the multiple sets of bearing needle rollers to mate with the outer ring, a storage cavity being provided inside the outer ring, and six sets of lubrication components being provided on both sides inside the storage cavity.

[0006] According to the aforementioned double-half inner ring deep groove ball bearing, the lubrication assembly includes an oil guide barrel, an oil outlet, an absorbent sponge, an oil outlet barrel, an oil inlet, and a spring. Six sets of oil outlet barrels are provided, each set penetrating the inner side of the storage cavity. Each of the six sets of oil outlet barrels has an oil guide barrel connected to its interior on its adjacent side. Each of the six sets of oil guide barrels has an oil outlet on its adjacent side. Each of the six sets of oil guide barrels has an absorbent sponge connected to the bearing needle rollers on its adjacent side. Oil inlets are provided on both sides of the oil outlet barrel away from the oil guide barrel. Each of the six sets of oil outlet barrels has a spring connected to the inner side of the storage cavity on its opposite side.

[0007] According to the aforementioned double-half inner ring deep groove ball bearing, six sets of receiving grooves are provided on both sides of the inner surface of the outer ring of the bearing, and the six sets of receiving grooves are matched with the oil guide barrel. Furthermore, an opening is provided at the far end of each of the six sets of receiving grooves, and the opening is matched with the oil outlet barrel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a double-half inner ring deep groove ball bearing, including a bearing outer ring 1, bearing needle rollers 3 evenly arranged on both sides inside the bearing outer ring 1, a cage 11 is provided on the outside of multiple sets of bearing needle rollers 3, and a bearing inner ring 2 that mates with the bearing outer ring 1 is provided on the inside of the multiple sets of bearing needle rollers 3, a storage cavity 8 is provided inside the bearing outer ring 1, and six sets of lubrication components are provided on both sides inside the storage cavity 8. This solves the problem that the existing double-half inner ring deep groove ball bearing requires manual lubrication, which is cumbersome and increases the number of steps for operators.

[0023] The lubrication assembly includes an oil guide tank 4, an oil outlet 10, an absorbent sponge 6, an oil outlet 5, an oil inlet 9, and a spring 7. There are six sets of oil outlet tanks 5, each set penetrating the inside of the storage cavity 8. On the side of each set of oil outlet tanks 5 adjacent to each other, there is an oil guide tank 4 communicating with its interior. On the side of each set of oil guide tanks 4 adjacent to each other, there is an oil outlet 10. On the side of each set of oil guide tanks 4 adjacent to each other, an absorbent sponge 6 is connected to fit against the bearing needle roller 3. On both sides of the end of the oil outlet tank 5 furthest from the oil guide tank 4, there are oil inlets 9. The oil inlet 9 and the six sets of oil outlets 5 are each equipped with a spring 7 connected to the inside of the storage cavity 8 on the side away from each other. The protrusion of the bearing needle roller 3 can lift the guide oil tank 4, which can then drive the oil outlet 5 and the oil inlet 9 to move into the interior of the storage cavity 8. This allows the lubricating oil inside the storage cavity 8 to enter the interior of the oil outlet 5 and the guide oil tank 4 through the oil inlet 9, and finally be discharged through the oil outlet 10 and absorbed by the absorbent sponge 6. The absorption of the absorbent sponge 6 can realize the automatic lubrication function of the bearing needle roller 3.

[0024] The bearing outer ring 1 has six sets of storage grooves on both sides inside, which cooperate with the oil guide tank 4. The opposite ends of the six sets of storage grooves have openings that cooperate with the oil outlet tank 5. The design of the storage grooves facilitates the movement and storage of the oil guide tank 4. The design of the openings facilitates the installation and movement of the oil outlet tank 5 and also blocks and seals the oil inlet 9 to prevent the continuous discharge of lubricating oil. The top and bottom of the outer side of the bearing outer ring 1 have oil inlet holes, and the inside of the oil inlet holes is covered with a sealing cap. The opening of the oil inlet holes and the cooperation of the sealing caps facilitate the filling and sealing of lubricating oil by the operators. The cage 11 has multiple sets of through grooves inside, and bearing needle rollers 3 are rotatably installed inside the multiple sets of through grooves to facilitate the fixed installation of the cage 11 and the bearing needle rollers 3. The oil guide tank is made of a cylindrical structure and cooperates with the bearing needle rollers to facilitate the pushing and lifting of the oil guide tank by the bearing needle rollers.

[0025] Working principle: During use, the rotation of the outer ring 1 and above of the bearing outside the inner ring 2 and the bearing needle roller 3, and the rotation of the outer ring 1 and above of the bearing, can drive the oil guide tank 4 to be placed on top of the bearing needle roller 3. The protrusion of the bearing needle roller 3 can lift the oil guide tank 4, and then the oil guide tank 4 can drive the oil outlet tank 5 to be raised into the storage cavity 8, realizing the compression of the spring 7. The movement of the oil outlet tank 5 can also drive the oil inlet 9 into the storage cavity 8 to release the seal on the oil inlet 9, and then the lubricating oil inside the storage cavity 8 can enter the oil outlet tank 5 and the oil guide tank 4 through the oil inlet 9, and finally be discharged through the oil outlet 10. Then, the design of the adsorption sponge 6 can adsorb the lubricating oil. Finally, the adsorption sponge 6 and the bearing needle roller 3 are designed to fit together to achieve the lubrication of the outside of the bearing needle roller 3.

[0026] When the outer ring 1 of the bearing drives the oil guide 4 to disengage from the bearing needle roller 3, the elastic restoring force of the spring 7 can drive the oil guide 4 and the oil outlet 5 to return to their original positions. This causes the oil outlet 5 to move the oil inlet 9 into the interior of the inlet, thereby blocking the oil inlet 9 and preventing the continuous entry of lubricating oil. This achieves intermittent oil output, facilitating the automatic lubrication function of the bearing's interior in the future. It eliminates the need for manual lubrication by operators, increasing the convenience and flexibility of bearing lubrication.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
