Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a bearing with good heat dissipation. Background Technology

[0002] As a crucial sliding bearing component in mechanical equipment, the bearing bush generates a significant amount of heat during operation due to friction between the shaft and the bush. If this heat cannot be dissipated in time, the bearing bush temperature will rise, leading to a decline in the material properties of the bush, accelerated wear, and potentially even bearing bush ablation, severely impacting the normal operation and service life of the mechanical equipment. Existing bearing bush heat dissipation structures have limitations in terms of heat dissipation efficiency and effectiveness.

[0003] Therefore, it is of great significance to provide a bearing with good heat dissipation to solve the problems existing in the current technology. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a bearing with good heat dissipation to solve the problem that the existing bearing heat dissipation structure has certain limitations in heat dissipation efficiency and effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bearing bush with good heat dissipation includes a bearing bush body. A central lubricating oil groove is formed in the middle of the inner wall of the bearing bush body. A dispersing lubricating oil groove is formed on the side of the central lubricating oil groove. The dispersing lubricating oil grooves are asymmetrically distributed on both sides. Each dispersing lubricating oil groove has an oil return hole at its end. Two reinforcing ribs are provided on the outer wall of the bearing bush body. The interior of the reinforcing ribs is a cavity. The cavity is connected to the dispersing lubricating oil groove through the oil return hole.

[0007] Preferably, both ends of the bearing body are fixedly connected to fixing ears, and the surface of the fixing ears is provided with mounting holes.

[0008] Preferably, the dispersed lubricating oil grooves are distributed at an angle in the same direction.

[0009] Preferably, sealing strips are provided on both the front and rear sides of the inner wall of the bearing body.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through the design of a central lubricating oil groove and a dispersed lubricating oil groove, effectively guides the flow of lubricating oil within the inner wall of the bearing bush. During the flow process, the lubricating oil can carry away the heat generated by the friction between the shaft and the bearing bush, achieving good lubrication and heat dissipation. The dispersed lubricating oil grooves are asymmetrically distributed on both sides and inclined in the same direction, optimizing the flow path of the lubricating oil, improving the flow efficiency of the lubricating oil, and further enhancing the heat dissipation effect.

[0012] 2. The hollow structure inside the reinforcing rib is connected to the lubricating oil distribution groove through the oil return hole, forming a lubricating oil circulation channel. After lubrication and heat dissipation, the lubricating oil can enter the hollow part of the reinforcing rib through the oil return hole and then flow back to the lubricating oil supply system, realizing the recycling of lubricating oil. At the same time, the reinforcing rib can also assist in heat dissipation and improve the overall heat dissipation performance of the bearing.

[0013] 3. The design of the fixing lugs and mounting holes makes the installation and removal of the bearing bush more convenient and quick, improving installation efficiency.

[0014] 4. The sealing strips on the front and rear sides of the inner wall of the bearing shell effectively prevent lubricating oil leakage, ensure sufficient supply and effective circulation of lubricating oil inside the bearing shell, and further improve the heat dissipation and lubrication effect of the bearing shell.

[0026] Please see Figure 1-3 This utility model provides a technical solution for a bearing with good heat dissipation:

[0027] A bearing bush with good heat dissipation includes a bearing bush body 1. A central lubricating oil groove 2 is formed in the middle of the inner wall of the bearing bush body 1, and dispersing lubricating oil grooves 3 are formed on the sides of the central lubricating oil groove 2. The dispersing lubricating oil grooves 3 are asymmetrically distributed on both sides, and each dispersing lubricating oil groove 3 has an oil return hole 8 at its end. Two reinforcing ribs 7 are provided on the outer wall of the bearing bush body 1. The interior of the reinforcing ribs 7 is hollow, and the cavity inside them communicates with the dispersing lubricating oil grooves 3 through the oil return holes 8.

[0028] Furthermore, both ends of the bearing body 1 are fixedly connected with fixing ears 4, and the surface of the fixing ears 4 is provided with mounting holes, through which the bearing can be conveniently installed on mechanical equipment.

[0029] Furthermore, the lubricating oil distribution grooves 3 are inclined in the same direction, which facilitates the flow and heat dissipation of the lubricating oil. Meanwhile, sealing strips are provided on both the front and rear sides of the inner wall of the bearing body 1. These sealing strips prevent lubricating oil leakage and ensure effective circulation of the lubricating oil within the bearing.

[0030] In practical use, the bearing bush is first installed in the corresponding position on the mechanical equipment through the mounting holes on the fixing lug 4. When the mechanical equipment is running, the shaft rotates on the inner wall of the bearing bush body. Lubricating oil enters the interior of the bearing bush through the central lubricating oil groove 2, and then flows along the dispersed lubricating oil groove 3, absorbing the heat generated by the friction between the shaft and the bearing bush during the flow. Since the dispersed lubricating oil grooves 3 are inclined in the same direction, the lubricating oil can flow smoothly to the end of the dispersed lubricating oil grooves 3, and enter the hollow part of the reinforcing rib 7 through the oil return hole 8, and finally flow back to the lubricating oil supply system, completing one circulation and heat dissipation process of the lubricating oil. At the same time, the sealing strips on the front and rear sides of the inner wall of the bearing bush body 1 ensure that the lubricating oil does not leak, maintains the stable circulation of the lubricating oil inside the bearing bush, and thus continuously and effectively removes the heat generated during the operation of the bearing bush, ensuring that the bearing bush operates stably at a lower temperature, improving the service life of the bearing bush and the reliability of the mechanical equipment.

[0031] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
