[0002] A needle roller bearing is a roller bearing with cylindrical rollers. Relative to its diameter, the rollers are both thin and long, and such rollers are called needle rollers. Although having a small cross-section, the bearing still has a high load-bearing capacity. The needle roller bearing is equipped with thin and long rollers (roller diameter D≤5mm, L / D≥2.5, L is the roller length). Therefore, the radial structure is compact. When its inner diameter size and load capacity are the same as those of other types of bearings, the outer diameter is the smallest, and it is especially suitable for support structures where the radial installation size is limited. A non-standard bearing, that is, a non-standard bearing, generally speaking, is a bearing that does not conform to the outer dimension regulations of the national standard, that is, all bearings with outer dimensions different from those specified by the national standard.

[0003] The stability and mating tightness of some existing needle roller bearings are crucial because they may be unstable during connection, resulting in accidents. Instability during installation will cause the fit between the bearing and its seat hole to be not tight, increasing the risk of detachment. Vibration during mechanical operation will cause the bearing to gradually loosen, further increasing the clearance and the risk of detachment. For this reason, a needle roller non-standard bearing that is convenient to install is proposed to solve the above problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 , Figure 3 , Figure 4 As an embodiment provided by the present utility model: A needle roller non-standard bearing that is easy to install includes an outer shell 1, which is the main component of the bearing and is responsible for accommodating the internal rotating device. It provides a stable external structure to ensure the correct alignment and operation of all other components. A rotating component for rotation is rotatably connected inside the outer shell 1, and the function of this component is to enable the internal components to rotate and ensure the smooth operation of the bearing. A protective shell 9 is fixedly connected to the bottom of the outer shell 1 to prevent external contaminants from entering the bearing interior.

[0032] Inside the protective case 9, a plurality of connection plates 15 are fixedly connected, which play a role in supporting and fixing other components. At the bottom of each of the plurality of connection plates 15, a rotating plate 13 is rotatably connected. The rotating plate 13 can rotate on the connection plate 15, thereby allowing the movement of internal components. On the outer side of the rotating plate 13, a rotating block 12 is fixedly connected, which is responsible for transmitting the rotational movement of the rotating plate 13 to other components. The outer side of the rotating block 12 is in contact with the inner side of the fixing frame 11, so that the movement coordination between the rotating block 12 and the fixing frame 11 can be achieved. The outer side of the rotating plate 13 is in contact with the inside of the fixing frame 11. Ensure that the fixing frame 11 can stably support the movement of the rotating plate 13.

[0033] At the other end of the rotating block 12, a rotating rod 17 is fixedly connected. The function of the rotating rod 17 is to transmit rotational power and connect with other components. On the outer side of the rotating rod 17, a fixing disk 14 is fixedly connected to stabilize the movement of the rotating rod 17. The outer side of the rotating block 12 is more connected to the fixing frame 11. This connection method allows the fixing frame 11 to freely rotate or adjust its position inside the protective case 9, thereby enhancing the flexibility of the device. The outer side of the fixing frame 11 is rotatably connected inside the protective case 9. On the right side of the fixing frame 11, a handle 10 is fixedly connected. The user can perform operations or adjustments through the handle 10.

[0034] The design of the handle 10 may take into account ergonomics to provide a comfortable grip when operating. The outer side of the handle 10 is slidably connected inside the arc 16. The rotating block 12 is set to be hollow. At the same time, the rotating block 12 is designed to be hollow, which may be for the purpose of reducing weight or facilitating the layout and function realization of the internal space. The handle 10 is slidably connected inside the protective case 9, and on one side of the protective case 9, an arc 16 is fixedly connected. In addition, an arc 16 is fixedly connected to one side of the protective case 9. This connection provides support for the sliding track of the handle 10 and may affect the appearance and structural stability of the entire device.

[0035] Refer to Figure 1 、 Figure 2 , the rotating assembly includes a plurality of needle rollers 2. Inside the plurality of needle rollers 2, a rotating ring 5 is rotatably connected. The design purpose of these needle rollers 2 inside the assembly is to achieve rotation or reduce friction. Inside each needle roller 2, a rotating ring 5 is assembled. Such a structural design enables the rotating ring 5 to rotate smoothly inside the needle roller 2, thereby improving the operating efficiency of the overall mechanical system. At the bottom of the oil storage tank 8, an outlet is provided. This design enables the oil in the oil storage tank 8 to be effectively discharged or flow, ensuring the continuous operation of the system and the effective utilization of the oil.

[0036] The setting of the bottom outlet may also facilitate the replacement or drainage of the oil. A plurality of needle rollers 2 are rotatably connected inside the housing 1. Inside the plurality of needle rollers 2, a first sandwich layer 3 is rotatably connected. At the top of the first sandwich layer 3, an oil inlet 6 is fixedly connected. A plug 7 is slidably connected to the top of the oil inlet 6. Inside the needle rollers 2, each needle roller 2 is rotatably connected to the first sandwich layer 3. The first sandwich layer 3 is located inside the needle rollers 2, providing additional support for the system. At the top of the first sandwich layer 3, an oil inlet 6 is fixedly connected. This oil inlet 6 is used to introduce lubricating oil or other fluids to ensure the normal operation of the system.

[0037] At the top of the oil inlet 6, a slidably connected plug 7 is installed. This plug can be easily opened or closed when needed, facilitating the discharge of the oil. On the other side of the needle rollers 2, a second sandwich layer 4 is rotatably connected. An oil storage tank 8 is fixedly connected inside the first sandwich layer 3. The oil storage tank 8 is fixedly connected inside the first sandwich layer 3 and is stably installed inside the first sandwich layer 3. This structural design helps with the storage and management of the oil, ensuring an adequate supply of oil during the operation of the system.

[0038] Working principle: The staff manually passes the object to be connected to the bearing through the middle of the protective shell 9. At this time, the staff can manually pull the handle 10 to adjust the position of the fixing frame 11 inside the protective shell 9. Inside the handle 10, a rotating block 12 is connected through a rotating shaft. Inside the rotating block 12, a rotating plate 13 is fixedly connected. One end of the rotating plate 13 is rotatably connected to a connecting disk 15, and the other end is fixedly connected to a rotating rod 17 and a fixed disk 14. Since the fixing frame 11 will drive the three rotating shafts connected inside it to drive the rotating block 12 when the handle 10 is pulled, the rotating plate 13 can be controlled to adjust its position. After the object is connected to the bearing, the plug 7 can be manually removed, and then lubricating oil can be poured into it. The lubricating oil will be stored in the oil storage tank 8 inside the first sandwich layer 3 and the second sandwich layer 4. When the rotating ring 5 is rotated, it will contact the plurality of needle rollers 2. There is an outlet at the bottom of the oil storage tank 8. When not rotating, the needle rollers 2 on both sides will block the outlet. Once it starts to rotate, the needle rollers 2 on both sides will bring out the lubricating oil from the ends close to both sides of the oil storage tank 8, thus smearing the lubricating oil on the rotating ring 5 and the end of the housing 1 close to the needle rollers 2, achieving the purpose of not having to adjust the lubricating oil inside it from time to time.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
