Technical Field

[0001] This utility model belongs to the technical field of mechanical transmission components, and relates to a rotating shaft. Background Technology

[0002] Rotary shafts play a crucial role in mechanical systems. They are the core components for realizing rotational motion and transmitting torque. Their performance is like the "heart and power indicators" of a mechanical system, directly and significantly affecting the operating efficiency and stability of the entire mechanical equipment.

[0003] However, during continuous operation of the rotating shaft, it will generate continuous friction with the bearing sleeve. This friction will continuously generate a large amount of heat. The continuous accumulation of heat can easily aggravate the wear between the rotating shaft and the bearing sleeve, shorten its service life. At the same time, the accumulation of heat can also cause the material properties of the rotating shaft to gradually deteriorate, resulting in a decrease in strength and hardness. Utility Model Content

[0004] The technical problem to be solved by this utility model is that during the continuous operation of the rotating shaft, it will form continuous friction with the bearing sleeve. This friction will continuously generate a lot of heat. The continuous accumulation of heat will easily aggravate the wear between the rotating shaft and the bearing sleeve, shorten its service life. At the same time, the accumulation of heat will also easily cause the material properties of the rotating shaft to gradually deteriorate, resulting in a decrease in strength and a decrease in hardness.

[0005] The present invention discloses a rotating shaft, comprising a rotating shaft body, an output end fixedly connected to one end of the rotating shaft body, a drive gear ring fixedly connected to the middle part of the rotating shaft body near the output end, and a heat dissipation component disposed in the middle part of the rotating shaft body near the drive gear ring.

[0006] The heat dissipation assembly includes a disc, a support plate, a fixed base plate, and four sets of self-tapping screws. The disc is rotatably connected to the center of the rotating shaft body near the drive gear ring. The support plate is fixedly connected to the bottom of the disc, and the fixed base plate is fixedly connected to the bottom of the support plate. The four self-tapping screws are respectively connected to the four corners of the fixed base plate.

[0007] The heat dissipation assembly also includes four sets of hollow wall tubes, four sets of cross support frames, and four sets of driven shafts. The four hollow wall tubes are all fixedly connected to the center of the disk. The four cross support frames are respectively fixedly connected to the center of the four sets of hollow wall tubes. The four driven shafts are respectively rotatably connected to the center of the four sets of cross support frames. The ends of the hollow wall tubes are provided with a flow guiding and dustproof mechanism.

[0008] The heat dissipation assembly also includes multiple sets of fan blades and four sets of driven gears. The fan blades are fixedly connected to the middle of the four sets of driven shafts, and the four driven gears are fixedly connected to the ends of the four sets of driven shafts near the drive gear ring. All driven gears mesh with the drive gear ring.

[0009] The flow guiding and dust prevention mechanism includes multiple sets of flow guiding blades and four sets of dust prevention plates. The flow guiding blades are respectively installed at one end of the four sets of hollow wall tubes, and the four dust prevention plates are respectively fixedly connected to the ends of the four sets of hollow wall tubes away from the flow guiding blades. The middle parts of the four sets of driven shafts are respectively rotatably connected to the middle parts of the four sets of dust prevention plates.

[0010] The dustproof plate has multiple sets of filter holes in the middle.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting up the heat dissipation component, the heat generated by friction during long-term operation of the rotating shaft body can be reduced and is not easily dissipated, thereby aggravating the wear of the rotating shaft body, shortening its service life, increasing equipment maintenance costs and downtime. At the same time, it can also prevent the output end from being in a high-temperature environment for a long time, which can easily lead to the gradual deterioration of its material properties, such as reduced strength and hardness. In severe cases, it may even lead to deformation and breakage of the output end, causing equipment failure and safety accidents.

[0012] By using a dust-proof and airflow-guiding mechanism, the heat dissipation effect of the heat dissipation components can be improved, allowing the airflow to be more concentrated and directed towards the output end. At the same time, it can also reduce the impact of dust on the normal operation of the heat dissipation components, thereby improving the stability and reliability of the heat dissipation components.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Example 1

[0024] like Figures 1-4 As shown, a rotating shaft includes a rotating shaft body 1, an output end 11 fixedly connected to one end of the rotating shaft body 1, a drive gear ring 12 fixedly connected to the middle part of the rotating shaft body 1 near the output end 11, and a heat dissipation component disposed in the middle part of the rotating shaft body 1 near the drive gear ring 12.

[0025] The heat dissipation assembly includes a disc 2, a support plate 21, a fixed base plate 22, and four sets of self-tapping screws 23. The disc 2 is rotatably connected to the center of the rotating shaft body 1 near the drive gear ring 12. The support plate 21 is fixedly connected to the bottom of the disc 2. The fixed base plate 22 is fixedly connected to the bottom of the support plate 21. The four self-tapping screws 23 are respectively connected to the four corners of the fixed base plate 22.

[0026] The heat dissipation assembly also includes four sets of hollow wall tubes 3, four sets of cross support frames 31, and four sets of driven shafts 32. The four hollow wall tubes 3 are all fixedly connected to the middle of the disk 2. The four cross support frames 31 are respectively fixedly connected to the middle of the four sets of hollow wall tubes 3. The four driven shafts 32 are respectively rotatably connected to the middle of the four sets of cross support frames 31. The ends of the hollow wall tubes 3 are provided with a flow guiding and dustproof mechanism.

[0027] The heat dissipation assembly also includes multiple sets of fan blades 4 and four sets of driven gears 41. The fan blades 4 are fixedly connected to the middle of the four sets of driven shafts 32, and the four driven gears 41 are fixedly connected to the ends of the four sets of driven shafts 32 near the drive gear ring 12. All driven gears 41 mesh with the drive gear ring 12.

[0028] During operation, when installing the output end 11, the bottom surface of the fixed base plate 22 needs to be aligned with the fixed surface. Then, the self-tapping screw 23 is rotated to fix the fixed base plate 22 and the fixed surface. The end of the output end 11 away from the rotating shaft body 1 needs to be installed at the output device. When the output device drives the output end 11 and the rotating shaft body 1 to rotate, the rotating shaft body 1 will drive the drive gear ring 12 to move synchronously.

[0029] When the drive gear ring 12 rotates, it meshes with the four sets of driven gears 41, thus driving the driven gears 41 to rotate. The rotation of the driven gears 41 will drive the driven shaft 32 to rotate in the middle of the cross support frame 31, and will also drive the fan blades 4 to rotate. The rotation of the fan blades 4 will intensify the airflow around the rotating shaft body 1, thereby increasing the airflow speed and thus dissipating heat at the connection between the output end 11 and the output device.

[0030] When dissipating heat from the rotating shaft body 1, the position of the disc 2 can be fixed by the support plate 21, the fixed base plate 22 and the self-tapping screws 23. This reduces the possibility that the disc 2 will be forced to move due to the rotation of the rotating shaft body 1, which would affect the stability of the heat dissipation component. In addition, the support plate 21, the fixed base plate 22 and the self-tapping screws 23 can also work with the disc 2 to provide auxiliary support for the rotating shaft body 1, thereby improving the stability of the rotating shaft body 1 during rotation.

[0031] This step, through the setting of the heat dissipation component, can reduce the heat accumulation caused by friction in the rotating shaft body 1 during long-term operation, which is not easy to dissipate, thereby aggravating the wear of the rotating shaft body 1, shortening its service life, increasing equipment maintenance costs and downtime. At the same time, it can also prevent the output end 11 from being in a high-temperature environment for a long time, which can easily lead to the gradual deterioration of its material properties, such as reduced strength and hardness. In severe cases, it may even cause the output end 11 to deform or break, resulting in equipment failure and safety accidents.

[0032] Example 2

[0033] like Figures 1-3 As shown, the flow guiding and dust prevention mechanism includes multiple sets of flow guiding blades 5 and four sets of dust prevention plates 51. The flow guiding blades 5 are respectively installed at one end of the four sets of hollow wall tubes 3, and the four dust prevention plates 51 are respectively fixedly connected to the end of the four sets of hollow wall tubes 3 away from the flow guiding blades 5. The middle parts of the four sets of driven shafts 32 are respectively rotatably connected to the middle parts of the four sets of dust prevention plates 51.

[0034] Multiple sets of filter holes 6 are opened in the middle of the dustproof plate 51.

[0035] When the heat dissipation component is working, the airflow it blows out flows to the output end 11 through the guide vane 5. With the guide vane 5, the airflow can be accelerated, the airflow speed can be increased, and the airflow can be guided to reduce the situation where the airflow easily disperses and weakens the heat dissipation effect.

[0036] With the dustproof plate 51 and filter holes 6, the amount of external dust that can easily drift into the hollow wall tube 3 from the port of the hollow wall tube 3 can be reduced, which would cause dust to adhere to the internal parts of the hollow wall tube 3 and affect its normal operation.

[0037] This step, through the setting of the airflow and dust prevention mechanism, can improve the heat dissipation effect of the heat dissipation components, making the airflow more concentrated and blowing towards the output end 11. At the same time, it can also reduce the impact of dust on the normal operation of the heat dissipation components, and improve the stability and reliability of the heat dissipation components.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

The present utility model is limited only by the claims and their full scope and equivalents.
