Description

Technical Field

[0001] This utility model relates to the field of transmission technology, and in particular to a heat-dissipating gear shaft with a vortex structure. Background Technology

[0002] In the field of transmission technology, gear shafts are core components for realizing power transmission and motion conversion. They combine the functions of gears for transmitting torque and shafts for support and positioning, and are widely used in mechanical equipment, automotive transmission systems, industrial machine tools and other scenarios.

[0003] However, existing gear shafts with heat dissipation functions still have obvious defects in actual use, especially in terms of ease of maintenance. Most heat dissipation gear shafts adopt an integrated design of gears and connecting shafts. When the gears need to be cleaned and maintained, the entire structure needs to be disassembled with the help of professional tools, which is cumbersome and time-consuming. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a heat-dissipating gear shaft with a vortex structure, which aims to improve the problems of traditional heat-dissipating gear shafts, such as poor maintenance convenience and cumbersome and time-consuming disassembly procedures.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A heat-dissipating gear shaft with a vortex structure includes a connecting shaft, a pneumatic gear disposed on the outside of the connecting shaft, a heat dissipation hole being formed inside the pneumatic gear, a fixing mechanism being disposed inside the pneumatic gear, the fixing mechanism including a first fixing plate, the outside of the first fixing plate being disposed inside the pneumatic gear, the inside of the first fixing plate being disposed outside the connecting shaft, a second spring being disposed inside the first fixing plate, and a fixing component being disposed at one end of the second spring.

[0007] The above technical solution involves pushing the second slider to rotate within the first fixed plate, thereby causing the second slider to push the second spring to contract. This causes the second slider to rotate away from the interior of the connecting block, allowing the first fixed plate of the fixed cylinder gear to be removed before disassembling the cylinder gear for maintenance. This ensures that the heat dissipation holes remain unobstructed, facilitating the disassembly of the cylinder gear and achieving the effect of keeping the heat dissipation holes unobstructed.

[0008] Preferably, the fixing component includes a second slider, the outside of which is disposed at one end of the second spring, the outside of which is rotatably connected to the inside of the first fixing disk, a connecting block is disposed outside the second slider, the outside of which is disposed inside the first fixing disk, and the bottom end of the connecting block is fixedly connected to the inside of the cylindrical gear.

[0009] Preferably, the fixing mechanism further includes a second fixing disk, the interior of which is rotatably connected with a locking tooth, one end of which is engaged with the interior of the pneumatic gear, and a third spring is provided on the exterior of the locking tooth, one end of which is located inside the second fixing disk.

[0010] Preferably, a baffle is provided inside the connecting shaft, and a slide rod is fixedly connected inside the connecting shaft.

[0011] Preferably, a first slider is slidably connected to the outside of the slide rod, and a fixing block is slidably connected to the inside of the first slider, with the outside of the fixing block disposed inside the connecting shaft.

[0012] Preferably, a first spring is provided on the outside of the fixing block, one end of the first spring is located inside the first slider, and a retaining plate is rotatably connected inside the fixing block.

[0013] Preferably, a positioning rod is fixedly connected to the outside of the first slider, and the positioning rod is slidably connected to the inside of the connecting shaft.

[0014] Preferably, the outer part of the positioning rod is disposed inside the pneumatic gear.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by pushing the fixing component to separate within the first fixing plate, the first fixing plate is released from fixing the cylinder gear, thereby making it easy to disassemble the first fixing plate and remove the cylinder gear, thus improving the convenience of maintenance.

[0017] 2. In this utility model, by pulling the card plate to make the fixing block leave the groove in the connecting shaft, the height of the fixing rod can be adjusted by pushing the first slider up and down. This allows the height of the positioning rod to be adjusted to correct the position of the cylindrical gear, thereby ensuring the precise meshing between the gears. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1:

[0029] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a heat-dissipating gear shaft with a vortex structure, including a connecting shaft 1, a pneumatic gear 2 disposed on the outside of the connecting shaft 1, a heat dissipation hole 4 opened inside the pneumatic gear 2, a fixing mechanism 3 disposed inside the pneumatic gear 2, the fixing mechanism 3 including a first fixing plate 301, the outside of the first fixing plate 301 disposed inside the pneumatic gear 2, the inside of the first fixing plate 301 disposed outside the connecting shaft 1, a second spring 302 disposed inside the first fixing plate 301, and a fixing component disposed at one end of the second spring 302;

[0030] Specifically, the connecting shaft 1 is used to support the rotation of the pneumatic gear 2. The pneumatic gear 2 is a cylindrical gear, which can effectively reduce gear meshing noise. The first fixed plate 301 is used to prevent the pneumatic gear 2 from shaking during rotation. The heat dissipation hole 4 is used to increase the heat dissipation area of ​​the pneumatic gear 2 and accelerate heat conduction. The second spring 302 is an arc spring used to support the fixing component to fix the first fixed plate 301 and the pneumatic gear 2. The fixing component is used to ensure that the pneumatic gear 2 will not loosen outside the connecting shaft 1, thereby achieving the effect of ensuring the meshing accuracy and transmission stability between the gear and other transmission components.

[0031] Reference Figure 2 and Figure 3 The fixing component includes a second slider 303, the outside of which is disposed at one end of the second spring 302. The outside of the second slider 303 is rotatably connected to the inside of the first fixing plate 301. A connecting block 304 is disposed on the outside of the second slider 303. The outside of the connecting block 304 is disposed inside the first fixing plate 301. The bottom end of the connecting block 304 is fixedly connected to the inside of the pneumatic gear 2.

[0032] Specifically, in this embodiment, the second slider 303 is composed of an L-shaped connecting plate and a slider, which facilitates the operator to disassemble the first fixed plate 301. The connecting block 304 has a groove inside that allows the second slider 303 to slide into, which facilitates the connection between the first fixed plate 301 and the pneumatic gear 2, thereby achieving the effect of not having to disassemble and reassemble the entire shaft system on a large scale.

[0033] Example 2:

[0034] Reference Figure 4 and Figure 5 The fixing mechanism 3 also includes a second fixing disk 305. The second fixing disk 305 is rotatably connected to a locking tooth 306. One end of the locking tooth 306 is engaged with the inside of the pneumatic gear 2. A third spring 307 is provided on the outside of the locking tooth 306. One end of the third spring 307 is located inside the second fixing disk 305.

[0035] Specifically, in this embodiment, the second fixing plate 305 has a groove on its outside to provide space for the cleaver 306 to rotate. One end of the cleaver 306 is triangular to facilitate fixing the pneumatic gear 2. The connection between the pneumatic gear 2 and the cleaver 306 has a groove that allows the cleaver 306 to rotate out, which facilitates fixing and removing the second fixing plate 305. The other end of the cleaver 306 is semi-cylindrical to allow the cleaver 306 to rotate on the second fixing plate 305. The third spring 307 is an arc spring used to stably hold the pneumatic gear 2 with the cleaver 306. By rotating the cleaver 306, the second fixing plate 305 can be removed to release the fixation of the pneumatic gear 2, thereby achieving the effect of installing gears of different specifications as needed.

[0036] Example 3:

[0037] Reference Figure 6 and Figure 7 Based on the above embodiments, this embodiment is used to solve the problem that the position of the cylindrical gear 2 on the connecting shaft 1 is difficult to adjust flexibly and stably, and is achieved through the following solution.

[0038] A baffle 5 is provided inside the connecting shaft 1, and a slide rod 6 is fixedly connected inside the connecting shaft 1; a first slider 7 is slidably connected to the outside of the slide rod 6, and a fixing block 8 is slidably connected inside the first slider 7. The outside of the fixing block 8 is located inside the connecting shaft 1; a first spring 9 is provided outside the fixing block 8, and one end of the first spring 9 is located inside the first slider 7. A retaining plate 10 is rotatably connected inside the fixing block 8; a positioning rod 11 is fixedly connected to the outside of the first slider 7, and the outside of the positioning rod 11 is slidably connected inside the connecting shaft 1; the outside of the positioning rod 11 is located inside the cylindrical gear 2.

[0039] Specifically, the connecting shaft 1 has a groove inside to facilitate the adjustment of the first slider 7 and the positioning rod 11. The baffle 5 is used to seal the connecting shaft 1 to prevent damage to the first slider 7 and the positioning rod 11 due to external factors. The slide rod 6 is used to prevent the connecting shaft 1 from breaking due to insufficient rigidity due to the groove. The first slider 7 is used to cooperate with the slide rod 6 to assist the positioning rod 11 in adjustment. One end of the fixing block 8 has a groove to facilitate the connection of the clamping plate 10, while the other end is T-shaped to facilitate the fixing of the positioning rod 11. The first spring 9 is used to support the fixing block 8 to fix the positioning rod 11. The clamping plate 10 consists of two rotating plates and a support column, which allows the operator to control the clamping plate 10 to adjust the height of the positioning rod 11, thereby achieving the effect of flexibly adjusting the gear position.

[0040] Working principle: When the pneumatic gear 2 needs to be disassembled for replacement, the second slider 303 is first pushed to slide within the first fixed plate 301. This causes the second spring 302 to contract, which in turn causes the second slider 303 to leave the connecting block 304. This further releases the first fixed plate 301 from fixing the pneumatic gear 2, allowing the first fixed plate 301 to be easily disassembled and the pneumatic gear 2 removed, thus improving the convenience of maintenance.

[0041] When the height of the pneumatic gear 2 needs to be adjusted according to its use, first remove the baffle 5 to expose the internal structure of the connecting shaft 1, then pull the clamping plate 10 to drive the fixing block 8 to slide inside the first slider 7, and then the fixing block 8 pushes the first spring 9 to retract, which in turn pushes the first slider 7 to slide up and down. Thus, the first slider 7 drives the positioning rod 11 to slide and adjust inside the connecting shaft 1, thereby adjusting the height of the positioning rod 11 to correct the position of the pneumatic gear 2, so as to ensure the precise meshing between the gears.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
