Description

Technical Field

[0001] The utility model relates to the technical field of transmission worms, in particular to a transmission worm structure which is easy to replace. Background Art

[0002] In the prior art, traditional transmission worm gear structures typically adopt an integrated design, where the worm shaft and worm sleeve form a single unit, with their length and pitch fixed during the production process. This type of integrated design offers high strength and stability in certain applications and is suitable for transmission applications requiring standardization. However, due to its integrated structure, adjustments to different lengths and pitches during use often require replacement of the entire transmission worm assembly, which not only increases replacement costs but is also time-consuming and labor-intensive.

[0003] However, as industrial production continues to increase its requirements for easier equipment maintenance and more flexible transmission structures, the traditional one-piece worm gear structure has gradually exposed its limitations:

[0004] Complex replacement: When the worm length needs to be adjusted or the pitch needs to be changed to adapt to different working requirements, the traditional one-piece molding structure is difficult to disassemble and assemble quickly. When replacing, the entire set of components needs to be dismantled as a whole, which increases equipment downtime and reduces production efficiency.

[0005] Poor adaptability: Traditional worm gears are designed with fixed lengths and pitches, lacking flexibility and unable to be adjusted to meet diverse application requirements. This results in the need for a variety of worm gear specifications for different transmission scenarios, increasing inventory pressure and management difficulties, and limiting the application scope of transmission equipment.

[0006] Therefore, the existing technology urgently needs a new worm structure design to solve the shortcomings of the traditional one-piece molded transmission worm in terms of disassembly, replacement and adaptability, so as to improve the flexibility and maintenance efficiency of the transmission system. Utility Model Content

[0007] The utility model aims to solve the technical problems existing in the prior art or related technologies.

[0008] The utility model relates to a transmission worm structure that is easy to replace, mainly comprising a shaft portion, a worm sleeve and a core shaft rod. The surface of the shaft portion is provided with an engagement groove, the inner side of the worm sleeve is provided with a sleeve hole that is the same as the sleeve hole that is sleeved on the surface of the shaft portion, and the inner side of the sleeve hole is provided with an engagement ridge, the engagement ridge and the engagement groove are adapted in size and position, the shaft portion is formed by a combination of multiple strip petals, and the inner side of the shaft portion is provided with an axial hole for the core shaft rod to pass through, the two ends of the core shaft rod are threadedly connected with nut sleeves, and the nut sleeves abut against the two ends of the shaft portion. Through the above structure, the utility model can quickly realize the replacement of the worm sleeve, while ensuring the stable connection of the core shaft rod, and facilitating maintenance operations.

[0009] In a preferred embodiment, the present invention can be further configured such that the worm sleeve and the meshing rib are integrally formed, and the surface of the worm sleeve is hardened. By designing the worm sleeve and the meshing rib as an integrally formed structure, assembly steps are reduced, and the hardening treatment increases service life, further enhancing the stability and durability of the transmission.

[0010] In a preferred embodiment, the present invention can be further configured such that: the number of the slivers is multiple and evenly distributed around the outer circumference of the core shaft, with each sliver having a fan-shaped cross-section. With this design, the slivers are evenly distributed around the outer circumference of the core shaft, effectively improving the overall stability and load-bearing capacity of the transmission device.

[0011] In a preferred embodiment, the present invention can be further configured such that adjacent segments are provided with ribs on their surfaces, which are then joined together to form a meshing groove. By providing ribs between adjacent segments and then joining together to form a meshing groove, the meshing degree between the segments is effectively improved, ensuring a secure connection between the worm sleeve and the shaft during transmission.

[0012] In a preferred embodiment, the present invention can be further configured such that the length of the engagement groove is equal to the length of the engagement edge, thereby limiting axial sliding displacement of the worm sleeve. By matching the lengths of the engagement groove and the engagement edge, the worm sleeve can be effectively prevented from axial displacement during transmission, thereby improving the stability of the transmission system.

[0013] In a preferred embodiment, the present invention can be further configured such that the outer surface of the core shaft is provided with anti-slip ridges to increase the friction between the worm sleeve and the core shaft, thereby improving transmission stability. The provision of anti-slip ridges can effectively prevent the worm sleeve from slipping during transmission, thereby ensuring transmission efficiency.

[0014] In a preferred embodiment, the present invention can be further configured such that the nut sleeve utilizes a double-thread design, wherein the inner thread securely connects to the core shaft, while the outer thread engages with both ends of the shaft, thereby achieving a more stable connection. This double-thread design ensures a secure connection between the core shaft and the shaft, facilitates replacement and disassembly, and improves maintenance efficiency and operational flexibility.

[0015] In summary, the utility model realizes the rapid disassembly, replacement and efficient installation of the transmission worm through the separable design, has higher adaptability and flexibility, and is suitable for various transmission scenarios.

[0016] The beneficial effects achieved by the utility model are:

[0017] 1. In the present invention, by adopting a split design, the shaft portion, the worm sleeve and the core shaft are separated independently, which can achieve rapid disassembly, thereby significantly improving the efficiency of disassembly and replacement of the transmission worm, and is particularly suitable for application scenarios where transmission parts are frequently replaced.

[0018] 2. In the present invention, the design based on the separate structure allows the shaft and the volute sleeve to be replaced separately, and shafts of different lengths and volute sleeves of different pitches can be flexibly combined to meet various transmission requirements, thereby significantly improving the adaptability and versatility of the system.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0026] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0027] The following is combined with Figures 1-4 Some embodiments of the present invention provide a transmission worm structure that is easy to replace.

[0028] The present invention relates to a transmission worm structure that is easy to replace, mainly comprising a shaft portion 100, a worm sleeve 200, and a core shaft 300. The shaft portion 100 has an engagement groove 101 on its surface, a sleeve hole is provided on the inner side of the worm sleeve 200, and an engagement ridge 210 is provided on the inner side of the sleeve hole. The engagement ridge 210 is adapted in size and position to the engagement groove 101. The shaft portion 100 is composed of a plurality of strip petals 110, and an axial hole is provided on its inner side for the core shaft 300 to pass through. Nut sleeves 310 are threadedly connected at both ends of the core shaft 300, and the nut sleeves 310 abut against both ends of the shaft portion 100.

[0029] In this embodiment, the mating connection between the meshing groove 101 and the meshing ridge 210 ensures that the volute sleeve 200 will not experience axial sliding or offsetting during transmission. Furthermore, because the shaft portion 100 is composed of a plurality of slivers 110, these slivers 110 are evenly distributed in the circumferential direction, resulting in smoother transmission. Each sliver 110 has a fan-shaped cross-section, further enhancing the load-bearing capacity and stability of the shaft portion 100. Furthermore, the surface of the core shaft 300 is provided with anti-slip ridges to increase friction with the volute sleeve 200 and prevent slipping under high load conditions.

[0030] To achieve greater durability and stability, the volute sleeve 200 and meshing rib 210 are integrally formed, and the surface of the volute sleeve 200 is hardened to extend its service life. Furthermore, the nut sleeve 310 features a double-thread design: the inner thread connects to the core shaft 300, while the outer thread engages the ends of the shaft 100, creating a more secure assembly structure and facilitating replacement and maintenance.

[0031] In another embodiment, the present invention can flexibly adjust the structure of the transmission worm according to different application requirements. The transmission worm in this embodiment still includes the shaft portion 100, the worm sleeve 200 and the core shaft 300, but the design is further optimized to enhance its adaptability.

[0032] In this embodiment, the length of the shaft portion 100 can be changed according to actual use requirements. Users can select shaft portions 100 of different lengths to meet different transmission distance requirements. At the same time, the pitch of the volute sleeve 200 can also be adjusted according to actual needs. Volute sleeves 200 of different pitches can be used in combination with the same core shaft 300, thereby achieving a wider range of applicability.

[0033] Furthermore, in this embodiment, by optimizing the number and distribution density of the slats 110, the number of slats 110 can be adjusted based on load requirements to further improve transmission efficiency and stability. When the transmission system requires higher torque, the number of slats 110 can be increased to enhance the strength and stability of the shaft portion 100.

[0034] To further enhance the convenience of the transmission system, this embodiment incorporates a quick-change mechanism: the nut sleeve 310 features a quick-release design that allows for rapid removal via rotation, enabling faster replacement of the shaft portion 100 and volute sleeve 200 and reducing maintenance time. Furthermore, the addition of a positioning snap-fit ​​structure between the engagement groove 101 and the engagement ridge 210 allows for automatic alignment during assembly, simplifying the assembly process.

[0035] Through the specific designs of the two aforementioned embodiments, the present invention demonstrates its advantages in adaptability, flexibility, and ease of maintenance. This worm gear structure not only adapts to a variety of application scenarios, but also significantly reduces the difficulty of replacement and maintenance through its detachable design, thus possessing a promising market application prospect.
