[0006] However, the above-mentioned mode has a prominent hardware structure problem, gear shaft needs to be lubricated and maintained after long time use Gear part, but since gear shaft is usually installed in gear box, speed reducer and other box bodies for use, the internal space of box body is narrow, and the operation space is limited, when lubricating, gear shaft needs to be rotated and maintained, the above-mentioned device lacks convenient lubricating mechanism, it is difficult to operate when lubricating bottom end position of gear part far from box opening, easy to cause lubrication dead angle, cause uneven wear of gear part, affect service life and performance of gear shaft. INVENTION CONTENTS

[0007] (I) technical problems solved

[0008] To address the shortcomings of existing technologies, this utility model provides a high-efficiency heat-dissipating gear shaft. This solves the problem that after prolonged use, gear shafts require lubrication and maintenance of their gear components. However, since gear shafts are typically installed in gearboxes, reducers, or other housings with limited internal space and operating space, lubrication requires rotating the gear shaft while performing maintenance. The aforementioned devices lack convenient lubrication mechanisms, making it difficult to lubricate the bottom portion of the gear component away from the housing opening. This can easily create lubrication dead zones, leading to uneven wear of the gear component and affecting the service life and performance of the gear shaft.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A high-efficiency heat-dissipating gear shaft includes a shaft body, which is stepped. A gear portion is fixedly connected to the outer surface of the shaft body, and a notched ring is slidably connected to the outer surface of the shaft body. An injection hole and a delivery ring are provided inside the notched ring, and the injection hole and the delivery ring are connected in communication. A positioning mechanism is fixedly connected to the inner wall of the notched ring, and the positioning mechanism includes a slider, which is fixedly connected to the inner wall of the notched ring.

[0012] Preferably, the shaft body has a sliding groove inside.

[0013] Preferably, the shaft body has two sets of external spiral heat dissipation grooves inside.

[0014] Preferably, the shaft body has two keyways inside.

[0016] Preferably, the inner wall of the through groove is provided with an inner spiral heat dissipation groove, and two retaining rings are fixedly connected inside the shaft body, with the two retaining rings respectively fixed on both sides of the through groove.

[0017] (III) Beneficial Effects

[0018] 1. When lubrication maintenance is required after the gear shaft has finished working, align the notch of the notched ring with the outermost sides of the shaft body, slide it downwards to fit the notched ring onto the outside of the shaft body, then rotate the notched ring 180 degrees so that the opening of the notched ring faces the upper end of the shaft body. At this time, align the slider inside the notched ring with the groove and inject lubricant into the infusion ring through the injection hole. The lubricant flows along the infusion ring and the surface of the shaft body to the gear part, which helps to distribute the lubricant evenly in the gear part, covering all corners, reducing lubrication dead spots, and making it convenient to lubricate and maintain the lower part of the gear part that is difficult to directly access and operate. This solves the problem of the traditional method being unable to reach this part and improves the convenience of maintenance work.

[0019] Second, the combination of two sets of external spiral heat dissipation grooves on the outer surface of the shaft and internal spiral heat dissipation grooves increases the contact area with air, improves heat exchange efficiency, and can quickly dissipate the heat generated by the gear shaft operation, thereby achieving a high-efficiency heat dissipation effect. Moreover, its spiral design helps the heat to be distributed and transferred more evenly on the surface and inside of the shaft, avoiding local overheating, thereby reducing thermal stress and thermal deformation, and extending the service life of the gear shaft.

[0026] This application provides a high-efficiency heat-dissipating gear shaft, effectively solving the problem of lubrication and maintenance of the gear section after prolonged use. However, since gear shafts are typically installed in gearboxes, reducers, or other housings with limited internal space and operating space, lubrication requires rotating the gear shaft while performing maintenance. The aforementioned devices lack convenient lubrication mechanisms, making lubrication of the bottom part of the gear section, away from the housing opening, difficult and prone to creating lubrication dead zones. This leads to uneven wear of the gear section, affecting the service life and performance of the gear shaft. Furthermore, after the gear shaft has finished working, lubrication and maintenance are still required. Align the notch of the notched ring with the outermost sides of the shaft body, slide it downwards to fit the notched ring onto the shaft body, then rotate the notched ring 180 degrees so that the opening of the notched ring faces the upper end of the shaft body. Align the slider inside the notched ring with the groove and inject lubricant into the infusion ring through the injection hole. The lubricant flows along the infusion ring and the surface of the shaft body to the gear part, which helps to distribute the lubricant evenly in the gear part, covering all corners, reducing lubrication dead spots, and making it convenient to lubricate and maintain the underside of the gear part that is difficult to directly access and operate. This solves the problem of traditional methods not being able to reach this part and improves the convenience of maintenance work.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that gear shafts require lubrication and maintenance after prolonged use. However, since gear shafts are typically installed in gearboxes, reducers, or other housings with limited internal space and operating space, lubrication requires rotating the gear shaft while performing maintenance. The aforementioned device lacks a convenient lubrication mechanism, making it difficult to lubricate the bottom portion of the gear shaft away from the housing opening. This can easily create lubrication dead zones, leading to uneven wear of the gear shaft and affecting its service life and performance. The overall concept is as follows: A high-efficiency heat-dissipating gear shaft includes a shaft body 11, which is stepped. A gear part 12 is fixedly connected to the outer surface of the shaft body 11. A notched ring 13 is slidably connected to the outer surface of the shaft body 11. An injection hole 14 and a delivery ring 15 are opened inside the notched ring 13. The injection hole 14 and the delivery ring 15 are connected. A positioning mechanism is fixedly connected to the inner wall of the notched ring 13. The positioning mechanism includes a slider 16, which is fixedly connected to the inner wall of the notched ring 13. A groove 17 is opened inside the shaft body 11, and the slider 16 is slidably connected to the groove 17. Inside the groove 17, the notch of the notched ring 13 matches the outer diameter of both sides of the shaft body 11. After the gear shaft finishes working, when lubrication maintenance is required, align the notch of the notched ring 13 with the outermost sides of both sides of the shaft body 11 (the shaft body 11 is stepped, with its size gradually decreasing from the center to both sides), and slide it downwards to fit the notched ring 13 onto the outside of the shaft body 11. At this time, rotate the notched ring 13 180 degrees so that the opening of the notched ring 13 faces the upper end of the shaft body 11. Then, align the slider 16 inside the notched ring 13 and slide it into the groove 17, through the injection hole 1. 4. Lubricant is injected into the infusion ring 15. The surface of the notched ring 13 and the surface of the gear part 12 are fitted with a certain gap. The lubricant flows along the surface of the infusion ring 15 and the shaft body 11 into the gear part 12, which helps the lubricant to be evenly distributed in the gear part 12, covering all corners, reducing lubrication dead spots, and making it convenient to lubricate and maintain the area below the gear part 12 that is difficult to directly access and operate. This solves the problem that it is difficult to reach this part by traditional methods and improves the convenience of maintenance work. After the lubrication work is completed, the notched ring 13 is slid out to restore the gear shaft to the working state.

[0029] The shaft body 11 has two sets of external spiral heat dissipation grooves 18 inside, which are located on both sides of the slide groove 17. The shaft body 11 also has two keyways 19 inside, which are located on both sides of the two sets of external spiral heat dissipation grooves 18. The shaft body 11 is installed in the gearbox or other operating environment, and power is transmitted through the gear part 12 connected to the outside of the shaft body 11. Matching keys can be installed in the two keyways 19 inside the shaft body 11, so that the gear can be easily installed on or removed from the shaft during assembly and maintenance.

[0030] The shaft body 11 has a through groove 21 inside, and an inner spiral heat dissipation groove 22 is formed on the inner wall of the through groove 21. Two retaining rings 23 are fixedly connected inside the shaft body 11. The two retaining rings 23 are fixed on both sides of the through groove 21 respectively. When the gear shaft is installed and put into use, the two sets of outer spiral heat dissipation grooves 18 on the outer surface of the shaft body 11 and the inner spiral heat dissipation grooves 22 inside the shaft body 11 work together to increase the contact area with air, improve the heat exchange efficiency, and can quickly dissipate the heat generated by the operation of the gear shaft. Moreover, its spiral design helps the heat to be distributed and transferred more evenly on the surface and inside of the shaft, avoiding local overheating, thereby reducing thermal stress and thermal deformation, and extending the service life of the gear shaft. (The inner spiral heat dissipation grooves 22 inside the shaft body 11 are machined by turning during production. After machining, the retaining rings 23 are installed inside the shaft body 11 by welding to enhance structural stability, reduce stress concentration caused by the presence of the through groove 21, and reduce the risk of breakage under stress.)

[0031] To address the problems existing in the prior art, this utility model provides a high-efficiency heat dissipation gear shaft. After the gear shaft has finished working, when lubrication maintenance is required, align the notch of the notched ring 13 with the outermost sides of both sides of the shaft body 11, and slide it downwards to fit the notched ring 13 onto the outside of the shaft body 11. Then rotate the notched ring 13 180 degrees so that the opening of the notched ring 13 faces the upper end of the shaft body 11. At this time, align the slider 16 inside the notched ring 13 and slide it into the slide groove 17. Inject lubricant into the infusion ring 15 through the injection hole 14. The lubricant flows along the infusion ring 15 and the surface of the shaft body 11 to the gear part 12, which helps the lubricant to be evenly distributed in the gear part 12, covering all corners, reducing lubrication dead spots, and can conveniently lubricate and maintain the lower part of the gear part 12, which is difficult to directly access and operate, solving the problem that it is difficult to reach this part in the traditional way, and improving the convenience of maintenance work.

[0032] Working principle:

[0033] The first step is to install the shaft body 11 in the operating environment such as a gearbox, and transmit power through the gear part 12 connected to the outside of the shaft body 11. Matching keys can be installed in the two keyways 19 opened inside the shaft body 11, so that the gear can be easily installed on or removed from the shaft during assembly and maintenance.

[0034] The second step involves lubrication maintenance of the gear shaft after its operation. Align the notch of the notched ring 13 with the outermost sides of the shaft body 11 (the shaft body 11 is stepped, with dimensions gradually decreasing from the center towards both sides). Slide the notched ring 13 downwards to fit it onto the shaft body 11. Then rotate the notched ring 13 180 degrees so that its opening faces the upper end of the shaft body 11. Align the slider 16 inside the notched ring 13 with the slide groove 17 and inject lubricant into the infusion ring 15 through the injection hole 14. The notched ring 13 and the gear part 12 have a certain gap, allowing the lubricant to flow along the infusion ring 15 and the shaft body 11 towards the gear part 12. This helps to evenly distribute the lubricant in the gear part 12, covering all corners and reducing lubrication dead zones. It also facilitates lubrication maintenance of the underside of the gear part 12, which is difficult to access directly, solving the problem of traditional methods being unable to reach the gear part 12. This addresses the issue in this area, improving the convenience of maintenance. After lubrication, the notched ring 13 is slid out to restore the gear shaft to its working state. When the gear shaft is in use after installation, the two sets of external spiral heat dissipation grooves 18 on the outer surface of the shaft body 11 and the internal spiral heat dissipation grooves 22 increase the contact area with air, improving heat exchange efficiency and quickly dissipating the heat generated by the gear shaft. Its spiral design helps the heat to be distributed and transferred more evenly on the surface and inside of the shaft, avoiding local overheating, thereby reducing thermal stress and thermal deformation, and extending the service life of the gear shaft. (The internal spiral heat dissipation grooves 22 inside the shaft body 11 are machined by turning during production. After machining, the retaining ring 23 is installed inside the shaft body 11 by welding to enhance structural stability, reduce stress concentration caused by the presence of the through groove 21, and reduce the risk of breakage under stress.)

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
