Description

Technical Field

[0001] This utility model relates to the technical field of winding machine accessories, specifically a fully enclosed toothed ring. Background Technology

[0002] A winding machine is a widely used piece of equipment in the production of electromagnetic components such as motors, transformers, and inductors. Its main function is to wind wires onto a bobbin according to a specific pattern. In the transmission system of a winding machine, the gear ring is one of the important transmission components, working in conjunction with gears to transmit power and convert speed. Currently, most traditional winding machine gear rings adopt an open or semi-open structure, which suffers from instability and other problems during use. Therefore, some new types of gear rings have emerged on the market.

[0003] For example, utility model patent CN208352123U discloses a gear ring for a winding machine, including a notched gear ring and a connector. The notched gear ring has a notch, and the connector is connected to the notched gear ring at the notch. This gear ring improves the structural stability and reduces noise during operation by modifying the notched gear ring into an assemblable closed gear ring. In actual use, the gear ring requires lubrication to reduce friction between the gear ring and other meshing parts. However, existing gear rings lack a lubrication mechanism, requiring frequent lubrication by operators. This can easily lead to insufficient lubrication due to untimely lubrication, increasing friction between the gear ring and other parts, resulting in increased wear and affecting service life and operational stability. Utility Model Content

[0004] The purpose of this invention is to provide a fully enclosed gear ring, which aims to improve the problem that existing winding machine gear rings do not have a mechanism for adding lubricating oil, which easily leads to insufficient oil in the gear ring and affects the life and operational stability of the gear ring.

[0005] This utility model is implemented as follows:

[0006] A fully enclosed toothed ring includes a toothed ring body and a splicing part. The toothed ring body has a notch on its side. The splicing part is located at the notch of the toothed ring body and is hollow inside. The hollow cavity of the splicing part is filled with lubricating oil. Guide rods are provided at both ends of the splicing part. The guide rods are connected to flow guide tubes. The flow guide tubes communicate with the hollow cavity of the splicing part. A first flow channel is provided inside the toothed ring body. The outward-facing end of the flow guide tube is inserted into the first flow channel of the toothed ring body. Multiple leakage holes are provided on the side of the toothed ring body.

[0007] Furthermore, the outer surface of the toothed ring body is uniformly provided with first teeth, and the outer surface of the splicing part is provided with second teeth. The first teeth and the second teeth are spliced ​​together to form continuous teeth.

[0008] Furthermore, the toothed ring body has slots at both ends of the notch, and the inner side of the toothed ring body is provided with a set screw aligned with the slots. The leakage hole on the toothed ring body is connected to the first flow channel.

[0009] Furthermore, the splicing part is provided with clips at both ends, the clips are inserted into the inner side of the clip slots, the middle of the clips is provided with a second flow channel, the second flow channel is connected to the inner cavity of the splicing part, and the flow guide tube is disposed inside the second flow channel.

[0010] Furthermore, the splicing part has guide openings on its side near both ends, and the guide rod is located inside the guide opening, with one end of the guide rod extending out of the guide opening.

[0011] Furthermore, a clamping knob is provided at one end of the guide rod that protrudes from the guide port. The clamping knob is clamped to the outer side of the splicing part, and a pair of sealing rings are provided at both ends of the outer side of the guide tube.

[0012] Furthermore, the tooth surfaces of the first and second teeth are hardened to form a wear-resistant layer, and the tooth ring body and splicing part are made of alloy steel.

[0013] Furthermore, it also includes a tape reel and a marking block, both of which are mounted on the side of the toothed ring body and do not interfere with each other. The tape reel and the marking block are detachably connected to the toothed ring body.

[0014] Furthermore, the tape reel has a fixing hole in the middle, and the tape reel is fixed to the side of the toothed ring body by bolts passing through the fixing hole.

[0015] Furthermore, the marking block is provided with multiple countersunk holes, and the marking block is fixed to the side of the toothed ring body by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model features a hollow splicing section with an appropriate amount of lubricating oil injected into it. The splicing section is then connected to the toothed ring body. During the rotation of the toothed ring, the lubricating oil in the splicing section enters the toothed ring body and drains through the oil leakage hole onto the inner side of the teeth, thus achieving the purpose of adding lubricating oil to the toothed ring. This eliminates the need for frequent lubricating oil addition by operators, simplifying the lubricating oil addition process. Only periodic replenishment of lubricating oil is required, making the operation simple and convenient.

[0018] 2. This invention utilizes a tape reel to control the tension of the conductor. The friction between the tape and the reel applies a stable tension to the conductor, preventing it from being too loose or too tight during winding and ensuring coil density and consistency. As the toothed ring rotates, the tape reel adjusts slightly according to changes in conductor tension, compensating for tension fluctuations in real time and maintaining stability during the winding process.

[0019] 3. This invention utilizes a marker block in conjunction with a sensor. As the gear ring rotates, the sensor detects the marker block, counting the number of turns and determining its position. Each time the marker is passed, the count is repeated, precisely controlling the number of turns wound. Serving as an identifier for the starting point or a specific location, it ensures the repeatability and accuracy of the winding process. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fully enclosed toothed ring includes a toothed ring body 1 and a splicing part 2. The toothed ring body 1 has a notch 12 on its side, and the splicing part 2 is located at the notch 12 of the toothed ring body 1, so that the notch 12 of the toothed ring body 1 can be opened according to processing requirements. Furthermore, the splicing part 2 has a hollow inner cavity filled with lubricating oil. Guide rods 3 are located at both ends of the splicing part 2, and these guide rods 3 are connected to flow guide tubes 31, which communicate with the hollow cavity of the splicing part 2. A first flow channel 15 is located inside the toothed ring body 1. The outer end of the flow guide tube 31 is inserted into the first flow channel 15 of the toothed ring body 1. Multiple leakage holes 16 are located on the side of the toothed ring body 1. This structure facilitates the injection of lubricating oil into the hollow cavity of the splicing part 2. During the rotation of the toothed ring body 1, the lubricating oil leaks out through the leakage holes 16 via the first flow channel 15 and the second flow channel 23 under centrifugal force, ensuring effective and continuous lubrication of the toothed ring. A transparent observation window can be provided on the side of the splicing part 2 to easily observe the amount of lubricating oil inside, allowing for timely replenishment when lubricating oil is insufficient.

[0030] like Figure 2 and Figure 3 As shown, the outer surface of the toothed ring body 1 is uniformly provided with first teeth 11, and the outer surface of the splicing part 2 is provided with second teeth 21. The first teeth 11 and the second teeth 21 are spliced ​​together to form continuous teeth. This structure facilitates the toothed ring body 1 to cooperate with the drive mechanism, and facilitates the drive mechanism to drive the toothed ring to rotate quickly.

[0031] like Figure 2 As shown, the toothed ring body 1 has slots 13 at both ends of the notch 12, and set screws 14 are provided on the inner side of the toothed ring body 1 aligned with the slots 13. The slots 13 facilitate the mating of the splicing part 2, allowing the splicing part 2 to connect with the toothed ring body 1. The set screws 14 facilitate the fixing of the splicing part 2, ensuring that the splicing part 2 is stable at the notch 12 of the toothed ring body 1. The drain hole 16 on the toothed ring body 1 communicates with the first flow channel 15.

[0032] like Figure 3 As shown, the splicing part 2 has clips 22 at both ends, which snap into the inside of the slots 13 to ensure stable installation of the splicing part 2. The clips 22 have a second flow channel 23 in the middle, which communicates with the inner cavity of the splicing part 2. The guide tube 31 is set inside the second flow channel 23. This structure facilitates the flow of lubricating oil inside the splicing part 2 into the toothed ring body 1, so that it can flow out from the drain hole 16.

[0033] like Figure 4As shown, the splicing part 2 has a guide port 24 near both ends on its side. The guide rod 3 is located inside the guide port 24, and one end of the guide rod 3 extends out of the guide port 24. This structure facilitates the movement of the guide rod 3 along the guide port 24, which facilitates the insertion of the flow guide tube 31 into the toothed ring body 1, and also facilitates the removal of the flow guide tube 31 from the toothed ring.

[0034] like Figure 5 As shown, a clamping knob 33 is provided at one end of the guide rod 3 that protrudes from the guide port 24. The clamping knob 33 is clamped to the outer side of the splice part 2 to facilitate the fixation of the flow guide tube 31 and ensure the stability of the flow guide tube 31. A pair of sealing rings 32 are provided at both ends of the outer side of the guide tube. The sealing rings 32 are used to seal the gaps between the flow guide tube 31, the toothed ring body 1, and the splice part 2.

[0035] like Figure 2 and Figure 3 As shown, the tooth surfaces of the first tooth 11 and the second tooth 21 are hardened to form a wear-resistant layer, enhancing the wear resistance of the tooth ring body 1. The tooth ring body 1 and the splicing part 2 are made of alloy steel materials, such as polyoxymethylene (POM) or nylon.

[0036] like Figure 1 As shown, it also includes a tape reel 4 and a marker block 5. Both the tape reel 4 and the marker block 5 are mounted on the side of the toothed ring body 1, and they do not interfere with each other. The tape reel 4 and the marker block 5 are detachably connected to the toothed ring body 1. The tape reel 4 can control the tension of the wire. Through the friction between the tape (or elastic belt) and the tape reel 4, a stable tension is applied to the wire, preventing the wire from being too loose (loose coil) or too tight (stretched and deformed) during winding. The marker block 5 works in conjunction with a sensor (such as a proximity switch or photoelectric sensor). When the toothed ring rotates, the sensor detects the marker block 5, counts the number of turns, and locates the position, ensuring the repeatability and accuracy of the winding process (such as the start / end position of each layer of winding).

[0037] like Figure 5 As shown, the tape reel 4 has a fixing hole 41 in the middle. The tape reel 4 is fixed to the side of the toothed ring body 1 by bolts passing through the fixing hole 41, which facilitates the disassembly and replacement of the tape reel 4.

[0038] like Figure 6 As shown, the marking block 5 is provided with multiple countersunk holes 51. The marking block 5 is fixed to the side of the toothed ring body 1 by bolts, which facilitates the flexible use of the marking block 5.

[0039] Working principle: During use, lubricating oil is injected into the splicing part 2 according to the usage requirements. Then, the splicing part 2 is clamped at the notch 12 of the toothed ring body 1. Then, the guide rod 3 drives the guide tube to be inserted into the toothed ring body 1, ensuring that the inner cavity of the splicing part 2 is connected to the first flow channel 15. Then, the set screw 14 is tightened to make the splicing part 2 stable at the notch 12. The lubricating oil inside the splicing part 2 will flow out into the first flow channel 15. When the toothed ring rotates, it is subjected to centrifugal force, and the lubricating oil will leak through the leakage hole 16 onto the inner side of the tooth, thereby achieving lubrication of the toothed ring body 1.

[0040] In summary, compared with the prior art, this application, by hollowing out the inner cavity of the splicing part 2 and injecting an appropriate amount of lubricating oil into the inner cavity of the splicing part 2, connects the splicing part 2 to the toothed ring body 1. In this way, during the rotation of the toothed ring, the lubricating oil in the splicing part 2 will enter the interior of the toothed ring body 1 and be discharged to the inner side of the teeth through the oil leakage hole, thereby achieving the purpose of adding lubricating oil to the toothed ring. It eliminates the need for frequent lubricating oil addition by the operator, simplifies the lubricating oil addition process, and only requires periodic replenishment of lubricating oil, making the operation simple and convenient.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
