Description

Technical Field

[0001] This utility model belongs to the field of roller technology, specifically a heat-dissipating roller bushing assembly. Background Technology

[0002] Rollers are a type of mechanical part that is widely used in industrial production and daily life. They are usually composed of a shaft, bearings, hubs and other parts.

[0003] The roller shaft is the core component. It is cylindrical and bears the main load and torque. When an external force is applied to the roller shaft, it is driven by a motor to rotate around its axis. During the rotation, the roller shaft can move the object connected to it, realizing operations such as crushing, squeezing and conveying the object. The bushing mainly serves as an intermediate layer between the roller shaft and other components, protecting the roller shaft from or minimizing wear.

[0004] During the rotation of the roller shaft within the bushing, friction exists between the roller shaft and the bushing. As the equipment continues to operate, the heat generated by friction accumulates, which can easily lead to an increase in the temperature of the bushing and the roller shaft. The temperature gauge in the passageway causes a decrease in the hardness and strength of the materials of the bushing and the roller shaft, accelerating the wear between the roller shaft and the bushing and causing deformation of the bushing.

[0005] Therefore, this utility model provides a heat-dissipating roller bushing assembly. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5 As shown, a heat-dissipating roller sleeve assembly according to an embodiment of the present invention includes a shaft body 1; two sleeve bodies 10 are provided at the end of the shaft body 1; the two sleeve bodies 10 are arranged opposite each other; a mounting base 19 is fixedly connected to the end of the sleeve body 10; a plurality of heat dissipation cavities 11 are formed in the middle of the sleeve body 10; two connecting grooves 12 are formed at the ends of two adjacent heat dissipation cavities 11; two sets of through holes 13 are formed in the middle of the sleeve body 10; a plurality of grooves 14 are formed on the outer side wall of the sleeve body 10; the grooves 14 A heat sink 15 is fixedly connected to the center of the groove 14 at the corresponding heat dissipation cavity 11; a retaining plate 16 is fixedly connected to the center of one of the heat dissipation cavities 11; an inlet pipe 17 is installed at the end of the bushing body 10; two retaining blocks 18 are fixedly connected to one end of the middle of the inlet pipe 17; the retaining blocks 18 are installed in the middle of the retaining plate 16; a lubrication assembly 2 is provided at one end of the middle of the bushing body 10; two mounting assemblies 3 are provided in the middle of the mounting base 19; during operation, the inlet pipe 17 is rotated to the designated position and then pulled outward to move the retaining blocks 18. The cooling medium exits from the middle of the clamping plate 16. At this time, the end of the inlet pipe 17 is separated from the middle of the clamping plate 16. The cooling medium is discharged into the corresponding heat dissipation cavity 11 through one end of the inlet pipe 17. It flows between the multiple heat dissipation cavities 11 through the two connecting grooves 12, so that the cooling medium fills the multiple heat dissipation cavities 11. After the end of the shaft 1 is placed in the middle of the bushing body 10, the cooling medium inside the bushing body 10 dissipates heat between the shaft 1 and the bushing body 10. At the same time, air circulates through multiple through holes 13, and multiple grooves 14 dissipate the heat on the surface of the bushing body 10 to the outside, thereby dissipating heat. The above structure can effectively absorb the heat generated between the shaft 1 and the bushing body 10, and remove the heat through heat exchange, thereby reducing the temperature of the shaft 1 and the bushing body 10. Furthermore, the cooperation between the through holes 13 and the heat sink 15 can increase the contact area between the bushing body 10 and the outside air, so that the heat generated inside the bushing body 10 can be quickly dissipated to the surrounding environment, improving the heat dissipation efficiency.

[0025] like Figures 2 to 4As shown, the lubrication assembly 2 includes an oil reservoir 21; the oil reservoir 21 is located at one end of the middle of the bushing body 10; an oil inlet valve 22 is fixedly connected to the end of the bushing body 10; an oil drain chamber 23 is provided in the middle of the bushing body 10; multiple oil drain holes 24 are provided on the inner side wall of the bushing body 10; the oil drain holes 24 are located at the corresponding positions of the oil drain chamber 23; a rod 25 is inserted into the middle of the oil drain chamber 23 and the oil reservoir 21; the rod 25 passes through the end of the bushing body 10; during operation, the oil inlet valve 22 is opened, and lubricant is injected into the oil reservoir 21 from the end of the oil inlet valve 22. The lubricating oil is stored inside the oil reservoir 21. When in use, the insert rod 25 is pulled outward, and one end of the insert rod 25 moves out from the end of the oil discharge chamber 23. The lubricating oil inside the oil reservoir 21 enters the oil discharge chamber 23 and is discharged through the oil discharge hole 24 between the bushing body 10 and the shaft 1. Then, the insert rod 25 is inserted again to block one end of the oil discharge chamber 23, stopping the discharge of lubricating oil. This lubricates the shaft 1 and the bushing body 10. Through the above structure, the lubricating oil can be periodically and quickly discharged between the shaft 1 and the bushing body 10, forming a layer of ink. This reduces friction between the shaft 1 and the bushing body 10, reduces wear, makes the shaft 1 rotate more smoothly, thereby reducing energy loss. It can also absorb heat between the shaft 1 and the bushing body 10 and carry the heat out of the contact area between the shaft 1 and the bushing body 10 during the discharge process, maintaining operational stability.

[0026] like Figures 3 to 5 As shown, the mounting assembly 3 includes two mounting slots 31; the two mounting slots 31 are located in the middle of the mounting base 19; the two mounting slots 31 are arranged opposite each other; a tapered rod 32 is threadedly connected to the side wall of the mounting slot 31; a mounting block 33 is slidably connected to the middle of the mounting slot 31; two springs 34 are fixedly connected to the side wall of the mounting block 33; the two springs 34 are arranged opposite each other; the ends of the springs 34 are fixedly connected to the middle of the mounting base 19; during operation, after the bushing body 10 is installed at the ends of the two shafts 1, the two bushing bodies 10 are placed in the corresponding positions in the equipment, and the tapered rod 32 is rotated so that one end moves into the mounting slot 31. The end of the tapered rod 32 pushes the mounting block 33 to slide upward, and the springs 34 elastically contract and are fixed to the equipment by the mounting block 33, thereby quickly installing the bushing body 10. The above structure enables the bushing body 10 to be quickly installed in the equipment, allowing operators to quickly disassemble and replace the bushing body 10, improving the efficiency of equipment installation and maintenance, and reducing equipment downtime.

[0027] like Figure 4 and Figure 5As shown, the mounting base 19 has two exhaust slots 4 in the middle; an air inlet pipe 41 is fixed to the side wall of the mounting base 19; the air inlet pipe 41 is positioned at the corresponding exhaust slot 4; the mounting base 19 has several exhaust holes 42 on the side near the bushing body 10; during operation, after the bushing body 10 and the shaft 1 are installed, the end of the air inlet pipe 41 is connected to an air pump, and the air pump discharges airflow into the air inlet pipe 41. After the airflow enters the exhaust slot 4, it passes through the multiple exhaust holes 42 and is discharged to the bushing body 10 and the mounting position, thereby removing dust and impurities from the surface of the bushing body 10. By blowing air onto the outer wall of the bushing body 10 through the above structure, a pressurized air layer can be formed, effectively preventing dust, impurities, and foreign objects from adhering to the surface of the bushing body 10. This reduces the accumulation of foreign objects, keeps the surface of the bushing body 10 clean, reduces wear on the surface of the bushing body 10, and improves heat dissipation efficiency.

[0028] like Figure 1 As shown, a heat-conducting layer 5 is provided on the outer wall of the bushing body 10; the heat-conducting layer 5 is fixed to the outer wall of the bushing body 10; during operation, when the bushing body 10 and the shaft 1 are in use, the contact area between the bushing body 10 and the outside air or other heat dissipation medium is increased, and heat exchange is accelerated. The above structure can improve the heat dissipation effect, keep the temperature low during long-term operation, reduce overheating that causes the performance of the shaft 1 and the bushing body 10 to decline, and reduce wear aggravation.

[0029] like Figure 1 As shown, a sealing ring 6 is fixedly connected to the end of the bushing body 10; the sealing ring 6 fits against the end of the shaft body 1; during operation, when the shaft body 1 and the bushing body 10 are connected and used, the sealing ring 6 intercepts external dust and impurities from entering the gap between the bushing body 10 and the shaft body 1. The above structure can effectively reduce the adhesion and accumulation of dust and impurities between the bushing body 10 and the shaft body 1, effectively reduce the aggravation of wear between the bushing body 10 and the shaft body 1, and effectively reduce corrosion caused by dust accumulation between the bushing body 10 and the shaft body 1, thereby protecting the bushing body 10 and the shaft body 1.

[0030] like Figure 1 As shown, the surface of the bushing body 10 is provided with a thermally conductive coating. During operation, when the bushing body 10 and the shaft 1 are in use, a heat conduction channel is formed in the coating. The heat on the surface of the shaft 1 is transferred to the coating. The filler quickly conducts the heat from the high temperature zone to the low temperature zone, accelerating the heat dissipation. Through the above structure, a uniform thin film can be formed on the surface of the bushing body 10, increasing the contact area between the bushing body 10 and the external environment, quickly transferring heat from the inside of the bushing body 10 to the external environment, and increasing the heat dissipation efficiency.

[0031] During operation, after rotating the inlet pipe 17 to the designated position, pull it outward to move the locking block 18 out of the middle of the locking plate 16. At this time, the end of the inlet pipe 17 separates from the middle of the locking plate 16, and the cooling medium is discharged through one end of the inlet pipe 17 into the corresponding heat dissipation cavity 11. It flows between the multiple heat dissipation cavities 11 through the two connecting grooves 12, so that the cooling medium fills the multiple heat dissipation cavities 11. After placing the end of the shaft 1 in the middle of the bushing body 10, the cooling medium inside the bushing body 10 dissipates heat from the shaft 1 and the bushing body 10. Multiple through holes 13 allow air to circulate, and multiple grooves 14 dissipate heat from the surface of the bushing body 10 to the outside, thus relieving heat. The oil inlet valve 22 is opened, and lubricating oil is injected into the oil storage chamber 21 from the end of the valve. The lubricating oil is stored inside the oil storage chamber 21. When in use, the insert rod 25 is pulled outwards, and one end of the rod 25 moves out from the end of the oil discharge chamber 23. The lubricating oil inside the oil storage chamber 21 enters the oil discharge chamber 23 and is discharged through the oil discharge hole 24 between the bushing body 10 and the shaft 1. Then insert the insertion rod 25 to block one end of the oil drain chamber 23, stopping the lubricating oil discharge, thereby lubricating the shaft body 1 and the bushing body 10. After installing the bushing body 10 on the ends of the two shaft bodies 1, place the two bushing bodies 10 in the corresponding positions in the equipment, rotate the tapered rod 32 so that one end moves into the mounting groove 31, the end of the tapered rod 32 pushes the mounting block 33 to slide upward, the spring 34 elastically contracts, and is fixed to the equipment by the mounting block 33, thereby quickly installing the bushing body 10. After the shaft body 1 is installed, the end of the air inlet pipe 41 is connected to the air pump. The air pump discharges airflow into the air inlet pipe 41. After the airflow enters the air outlet 4, it passes through multiple air outlet holes 42 and is discharged to the bushing body 10 and the installation position, thereby removing dust and impurities from the surface of the bushing body 10. During the use of the bushing body 10 and the shaft body 1, the contact area between the bushing body 10 and the outside air or other heat dissipation medium is increased, accelerating heat exchange. During the connection and use of the shaft body 1 and the bushing body 10, the sealing ring 6 intercepts external dust and impurities from entering the gap between the bushing body 10 and the shaft body 1. During the use of the bushing body 10 and the shaft body 1, heat conduction channels are formed in the coating, and the heat on the surface of the shaft body 1 is transferred to the coating. The filler quickly conducts heat from the high-temperature area to the low-temperature area, accelerating heat dissipation.
