Description

Technical Field

[0001] This application relates to the field of high-load shaft technology, and in particular to a high-load bearing with dustproof and waterproof properties. Background Technology

[0002] In the field of mechanical equipment, high-load bearings are key transmission components, and their performance and reliability directly affect the operating efficiency and lifespan of the entire machine. Traditional high-load bearings have many shortcomings in design and application, especially in lubrication, cooling, and dust and water protection.

[0003] First, traditional high-load bearings tend to generate a large amount of frictional heat under high-speed, heavy-load operating conditions, leading to an increase in bearing temperature. If lubrication is insufficient or improper, the internal friction coefficient of the bearing will increase significantly, accelerating bearing wear and even causing bearing failure.

[0004] Secondly, high-load bearings generate a large amount of heat during operation. If this heat cannot be dissipated in time, the bearing temperature will become too high, affecting its lifespan and performance. Traditional cooling methods often suffer from poor cooling efficiency and high energy consumption, making it difficult to meet the cooling requirements of high-load bearings. Utility Model Content

[0005] To address the shortcomings of traditional high-load bearings in terms of lubrication, cooling, and dust and water resistance, this application provides a high-load bearing with dust and water resistance properties.

[0006] This application provides a high-load bearing with dustproof and waterproof properties, employing the following technical solution:

[0007] A high-load bearing with dustproof and waterproof performance includes a base plate, a bearing housing fixedly connected to the upper surface of the base plate, a bearing housing fixedly disposed on the top of the bearing housing, a bearing inner shell rotatably disposed on the inner side of the bearing housing, and a lubrication mechanism disposed on the surface of the bearing housing.

[0008] The lubrication mechanism includes an oil cooling box fixed to the side of the bearing housing and a drive shaft rotatably connected to the bottom of the bearing housing. A linkage gear is fixedly connected to the front end of the drive shaft, and a drive gear is fixedly connected to the outer ring surface of the bearing inner housing. A circulation guide shell is fixedly connected to the bottom of the bearing housing. The drive shaft passes through the interior of the circulation guide shell, and several guide vanes are fixedly arranged on the surface of the drive shaft. A first liquid guide tube and a second liquid guide tube are fixedly embedded at the left and right ends of the circulation guide shell, respectively. The end of the second liquid guide tube away from the circulation guide shell extends into the interior of the oil cooling box. A semiconductor cooling chip is fixedly embedded inside the oil cooling box, and the interior of the oil cooling box is filled with lubricating oil.

[0009] Optionally, a cooling fan is fixedly embedded on the side of the oil cooling box, and the position of the cooling fan corresponds to the heat dissipation surface of the semiconductor cooling chip.

[0010] Optionally, the left end of the first liquid guide tube extends to the left side of the bearing housing, and a circulation drain pipe is fixedly connected to the left end of the first liquid guide tube. The end of the circulation drain pipe away from the first liquid guide tube extends between the bearing housing and the bearing inner housing.

[0011] Optionally, the inner wall of the oil cooling box is fixedly connected with a first flow guide baffle and a second flow guide baffle. The first flow guide baffle is L-shaped, and the first flow guide baffle and the second flow guide baffle are used to delay the flow time of the liquid inside the oil cooling box.

[0012] Optionally, a circulating inlet pipe is fixedly embedded on the side of the oil cooling box, and the end of the circulating inlet pipe away from the oil cooling box extends to the space between the bearing housing and the bearing inner housing.

[0013] Optionally, an annular protective cover is fixedly connected between the bearing housing and the bearing inner housing, and two annular protective covers are symmetrically distributed on the front and rear sides of the bearing housing and the bearing inner housing.

[0014] Optionally, the bottom end of the bearing housing is fixedly connected to two corresponding limiting mounting plates, and the transmission shaft is rotatably connected to the surface of the limiting mounting plates. The limiting mounting plates are used to limit and support the transmission shaft.

[0015] In summary, the high-load bearing with dustproof and waterproof performance provided in this application has the following technical effects.

[0016] 1. High-efficiency lubrication and cooling system: The lubrication mechanism enables the bearing to circulate and cool during use. When the bearing inner shell rotates, the transmission gear drives the linkage gear and transmission shaft to rotate, which in turn drives the guide vanes to rotate in the circulation guide shell, promoting the circulation of lubricating oil. The lubricating oil enters the oil cooling box through the second guide pipe, where it is cooled by the semiconductor refrigeration chip. Then, it flows back to the space between the bearing inner and outer shells through the first guide pipe, providing continuous cooling and lubrication for the bearing and effectively improving the stability and durability of the bearing under high load operation.

[0017] 2. Enhanced dust and water resistance: The annular protective cover fixedly connected between the bearing housing and the bearing inner housing effectively blocks external dust and moisture from entering the bearing, thereby enhancing the bearing's dust and water resistance. This design enables the bearing to maintain good operating condition in harsh working environments and extends the bearing's service life. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] Reference Figures 1-5 A high-load bearing with dustproof and waterproof properties includes components such as a base plate, bearing housing 1, bearing outer shell 2, bearing inner shell 3, lubrication mechanism 4, annular protective cover 5, and limiting mounting plate 6.

[0026] The base plate serves as the supporting foundation for the entire bearing. A bearing housing 1 is fixedly connected to its upper surface. The bearing housing 1, located on the base plate, is used to securely mount the bearing outer shell 2, ensuring stable bearing operation. The bearing outer shell 2 is fixedly connected to the top of the bearing housing 1, and its inner side is used for rotatably mounting the bearing inner shell 3. The design of the bearing outer shell 2 takes into account dust and water resistance requirements, and an appropriate gap is left between it and the bearing inner shell 3 to facilitate lubricant circulation and the installation of the protective cover.

[0027] The bearing inner housing 3 is located inside the bearing outer housing 2 and functions as a bearing through rotation. A transmission gear 404 is fixedly connected to the outer ring surface of the bearing inner housing 3 for engaging with the linkage gear 403 in the lubrication mechanism 4.

[0028] An oil cooling box 401 is fixed to the side of the bearing housing 1. It is filled with lubricating oil and a semiconductor cooling chip 409 is fixedly embedded therein for cooling the lubricating oil. A cooling fan 411 is also fixedly embedded on the side of the oil cooling box 401, and its position corresponds to the heat dissipation surface of the semiconductor cooling chip 409 to improve cooling efficiency.

[0029] The drive shaft 402 is rotatably connected to the bottom of the bearing housing 2, and a linkage gear 403 is fixedly connected to its front end for meshing with the drive gear 404 on the bearing inner housing 3. When the bearing inner housing 3 rotates, it will drive the drive shaft 402 to rotate.

[0030] The circulation guide shell 405 is fixedly connected to the bottom of the bearing housing 2, and the drive shaft 402 passes through its interior. The left and right ends of the circulation guide shell 405 are respectively fixedly embedded with a first liquid guide pipe 407 and a second liquid guide pipe 408 to realize the circulation flow of lubricating oil.

[0031] The guide vane 406 is fixedly mounted on the surface of the drive shaft 402. When the drive shaft 402 rotates, it will drive the guide vane 406 to rotate in the circulation guide shell 405, thereby promoting the circulation of lubricating oil.

[0032] The end of the circulating inlet pipe 415 away from the oil cooling box 401 extends between the bearing housing 2 and the bearing inner housing 3, and is used to introduce the cooled lubricating oil into the bearing. The circulating outlet pipe 412 is connected to the left end of the first guide pipe 407, and the end away from the first guide pipe 407 also extends between the bearing housing 2 and the bearing inner housing 3, and is used to drain the lubricating oil inside the bearing and send it back to the oil cooling box 401 for cooling.

[0033] The first guide baffle 413 and the second guide baffle 414 are fixedly connected to the inner wall of the oil cooling box 401 to delay the flow time of the liquid inside the oil cooling box 401 and improve the cooling effect. The first guide baffle 413 has an L-shaped design, which, together with the second guide baffle 414, forms a complex flow channel, increasing the residence time of the lubricating oil in the oil cooling box 401.

[0034] An annular protective cover 5 is fixedly connected between the bearing housing 2 and the bearing inner housing 3, symmetrically distributed on the front and rear sides of the bearing. The design of the annular protective cover 5 effectively prevents external dust and moisture from entering the bearing, thereby enhancing the bearing's dustproof and waterproof performance.

[0035] The limiting mounting plate 6 is fixedly connected to the bottom end of the bearing housing 2, and the positions are corresponding. The drive shaft 402 is rotatably connected to the surface of the limiting mounting plate 6, which is used to limit and support the drive shaft 402 to ensure its stability during operation.

[0036] The implementation principle of a high-load bearing with dustproof and waterproof performance according to an embodiment of this application is as follows: When the bearing inner shell 3 rotates, it drives the transmission gear 404 on it to rotate. The transmission gear 404 meshes with the linkage gear 403 in the lubrication mechanism 4, thereby driving the transmission shaft 402 to rotate. The guide vanes 406 on the transmission shaft 402 rotate in the circulation guide shell 405, pushing the lubricating oil from between the bearing outer shell 2 and the bearing inner shell 3 through the first guide pipe 407 into the circulation guide shell 405, and then through the second guide pipe 408 into the oil cooling box 401. In the oil cooling box 401, the lubricating oil is cooled by the semiconductor cooling chip 409, and at the same time, the cooling fan 411 dissipates heat from the heat dissipation surface of the semiconductor cooling chip 409, improving the cooling efficiency. The cooled lubricating oil re-enters between the bearing outer shell 2 and the bearing inner shell 3 through the circulation inlet pipe 415, providing continuous cooling and lubrication for the bearing.

[0037] Meanwhile, the annular protective cover 5 between the bearing housing 2 and the bearing inner housing 3 effectively prevents external dust and moisture from entering the bearing, enhancing its dustproof and waterproof performance. This design allows the bearing to maintain good operating conditions in harsh working environments, extending its service life.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
