Description

Technical Field

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

[0002] Heat-dissipating bearings are core components in rotating machinery used to support rotors and reduce frictional heat. Traditional bearings experience rapid temperature rise and poor heat dissipation under high-speed or heavy-load conditions, easily leading to lubrication failure and premature wear, making it difficult to meet the high reliability and long service life requirements of modern equipment. With the industrial development towards higher speeds and precision, there is an urgent need for a new type of heat-dissipating bearing structure that features rapid heat dissipation, a compact structure, and convenient maintenance to effectively control temperature rise, extend service life, and ensure continuous and efficient equipment operation.

[0003] Patent publication number CN209510934U discloses a bearing heat dissipation structure, including a drive shaft horizontally positioned in the middle, a bearing seat horizontally coaxially positioned on the outside of the drive shaft, a fixing ring on the right end of the outer side of the bearing seat, a plurality of heat dissipation fins vertically positioned at equal intervals on the outer side of the bearing seat to the left of the fixing ring, and bearings symmetrically positioned at both ends of the inner side of the bearing seat in conjunction with the drive shaft.

[0004] To address the heat dissipation issue, existing technologies employ multiple sets of aluminum heat sinks to increase the heat exchange area, significantly improving heat dissipation efficiency. This enables real-time heat dissipation during bearing use, preventing bearing seizure, ensuring stable operation, and achieving rapid cooling after bearing use to eliminate heat accumulation and cracking problems. However, limited heat dissipation still exists, which can lead to deformation or damage to internal components due to prolonged high-temperature operation. Utility Model Content

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-6As shown, this utility model provides a heat-dissipating bearing structure, including a bearing body 1. A lubrication and cooling mechanism 2 is provided on the surface of the bearing body 1. A water-cooling mechanism 3 is provided on one side of the lubrication and cooling mechanism 2. The lubrication and cooling mechanism 2 includes a ring housing 21, which is movably connected to the top surface of the bearing body 1. An oil inlet 22 is fixedly connected to the top surface of the ring housing 21. A mounting nut 23 is fixedly connected to the side surface of the ring housing 21. A drain hole 26 is provided on the bottom surface of the ring housing 21. The lubrication and cooling mechanism 2 includes an oil drain base plate 24. Plate 24 is movably connected to the bottom surface of bearing body 1. An oil storage tank 25 is provided inside the oil leakage base plate 24. An oil drain port 27 is fixedly connected to the bottom surface of the oil storage tank 25. A connecting mechanism 28 is provided on the bottom surface of the oil leakage base plate 24. The connecting mechanism 28 includes a second connecting plate 282, which is fixedly connected to the bottom surface of the oil leakage base plate 24. A connecting fixing rod 284 is movably connected inside the connecting mechanism 28. A first connecting plate 281 is movably connected to one end of the connecting fixing rod 284. A fixing nut 283 is threadedly connected to the outer wall of the connecting fixing rod 284.

[0027] In this embodiment, when cooling is achieved using the lubrication and cooling mechanism 2, after installation via the installable mounting nut 23, cooling lubricating oil is injected into the oil inlet 22. The cooling lubricating oil enters the bearing housing 21, flows into the balls through the drain hole 26, leaks through the balls into the oil reservoir 25, and is then discharged from the oil outlet 27. The oil drain base plate 24 can be fixed to the bottom of the bearing body 1 by tightening the fixing nut 283 and connecting the connecting fixing rod 284 between the first connecting plate 281 and the second connecting plate 282. The cooling lubricating oil reduces the wear of the bearing rings during use, thereby ensuring the service life of the bearing.

[0028] Example 2

[0029] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the water-cooling mechanism 3 includes a water-cooling box 33, which is fixedly connected to the top surface of the connecting mechanism 28. A liquid inlet box 31 is fixedly connected to one side of the water-cooling box 33, and a liquid inlet 32 ​​is fixedly connected to the top surface of the liquid inlet box 31. A liquid outlet box 34 is fixedly connected to the other side of the water-cooling box 33, and a liquid outlet 35 is fixedly connected to the bottom surface of the liquid outlet box 34. The bearing body 1 includes a heat dissipation plate 14, which is movably connected to one side of the water-cooling box 33. An outer ring 13 is fixedly connected to one side of the heat dissipation plate 14. A through hole 15 is opened on the surface of the outer ring 13 and on one side of the heat dissipation plate 14. An installation hole 16 is opened on the top surface of the outer ring 13. The installation hole 16 is engaged with the installation nut 23. A ball bearing 12 is movably connected to one side of the outer ring 13, and an inner ring 11 is movably connected to one side of the ball bearing 12.

[0030] In this embodiment, when using the bearing body 1, the inner ring 11 first drives the ball bearing 12 to roll, thereby driving the entire outer ring 13 to rotate. When it gets hot after a period of use, it first undergoes preliminary surface heat dissipation through the heat sink 14 and the through hole 15. Then, coolant is injected from the inlet 32 ​​into the inlet tank 31, and the water cooling tank 33 is used for further cooling. The coolant is discharged through the outlet 35, so that the coolant is repeatedly replaced. This allows heat to be quickly transferred from the heat source to the heat dissipation surface and carried away by passive heat dissipation, thereby improving the effectiveness of the device in dissipating heat from the outer ring of the bearing.

[0031] The working principle of this heat-dissipating bearing structure will be explained in detail below.

[0032] like Figure 1-6 As shown, when using the bearing body 1, the inner ring 11 first drives the ball 12 to roll, thereby driving the entire outer ring 13 to rotate. When it gets hot after a period of use, it first undergoes preliminary surface heat dissipation through the heat sink 14 and the through hole 15. It is then installed in the mounting hole 16 by the installable mounting nut 23, and further cooled by the lubrication and cooling mechanism 2. Cooling lubricating oil is injected into the oil inlet 22, enters the ring housing 21, flows into the ball 12 through the drain hole 26, and then leaks into the oil reservoir 25 through the ball 12. Finally, it is discharged from the oil outlet 27. The oil drain base plate 24 can be fixed to the bottom of the bearing body 1 by tightening the fixing nut 283 and connecting the connecting fixing rod 284 between the connecting plate 1 281 and the connecting plate 282. Finally, coolant is injected into the liquid inlet 32 ​​and flows into the liquid inlet tank 31. It is then cooled again by the water cooling box 33, and the coolant is discharged through the liquid outlet 35, thus achieving repeated replacement of the coolant.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
