[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection.
[0019] Example 1:
[0020] like Figures 1-6 As shown, the utility model provides a damping shaft, including a base plate 1, the base plate 1 is provided with an elastic sleeve 2, the inner side of the elastic sleeve 2 is provided with a first plane 3, the elastic sleeve 2 is movably connected to a shaft 4, the shaft 4 includes an assembly section 5 and a main shaft section 6, the main shaft section 6 is provided with a second plane 7, the main shaft section 6 is provided with a fixing hole 8, the fixing hole 8 is fixedly connected to a fixing bolt 9, and the assembly section 5 is fixedly installed with an assembly part 10. The elastic sleeve 2 is an extension structure of the base plate 1, and an opening 11 is provided in the middle of the elastic sleeve 2. The assembly part 10 includes a fixing plate 12, a connecting plate 13 and an assembly plate 14, the fixing plate 12 is fixedly connected to the assembly section 5, and the fixing plate 12 is fixedly connected to the assembly plate 14 through the connecting plate 13. The shaft 4 is made of stainless steel. The assembly section 5 is a flat shaft structure.
[0021] Through the above technical scheme, the base plate 1 of the utility model is provided with an elastic sleeve 2, and the shaft rod 4 is movably installed through the elastic sleeve 2. A first plane 3 is provided on the inner side of the elastic sleeve 2, and a second plane 7 is provided on the main shaft section 6 of the shaft rod 4. In the initial state of the rotating shaft, the first plane 3 on the inner side of the elastic sleeve 2 is fitted with the second plane 7 of the main shaft section 6, so that the shaft rod 4 is temporarily fixed in the elastic sleeve 2. When the shaft rod 4 rotates relative to the elastic sleeve 2, the first plane 3 is separated from the second plane 7. At this time, the shaft rod 4 stretches the elastic sleeve 2, causing the elastic sleeve 2 to undergo elastic deformation. At this time, the elastic sleeve 2 applies pressure to the shaft rod 4, thereby increasing the friction between the elastic sleeve 2 and the shaft rod 4. The shaft rod 4 is subjected to a damping force when rotating, so that the utility model has a damping sense when rotating. The utility model achieves the damping sense of the rotating shaft through a simple structure, thereby reducing the production cost of the rotating shaft.
[0022] Example 2:
[0023] like Figures 1-6As shown, to enhance the operational feel and user experience, a rotating shaft often requires a damping function. Traditional damping rotating shafts are complex in structure, which not only increases production difficulty but also costs. To address these issues, the design of a new damping rotating shaft aims to simplify the structure while ensuring effective damping. The base plate 1 of the present invention serves as the fixed foundation for the rotating shaft, providing support and mounting functions. An elastic sleeve 2 is mounted on the base plate 1, with a first flat surface 3 defined on its inner side. The shaft 4 consists of two parts: an assembly section 5 and a main shaft section 6. The main shaft section 6 has a second flat surface 7, which is used for secure connection to other components, while the main shaft section 6 has a hole for securing. The shaft 4 connects to a fixing pin 9 on the base plate 1 through a fixing hole 8, ensuring the stability and accuracy of the shaft 4 during operation. In the initial state of the rotating shaft structure, the first flat surface 3 on the inner side of the elastic sleeve 2 aligns with the second flat surface 7 of the main shaft section 6, temporarily securing the shaft 4 within the elastic sleeve 2. This temporary fixation occurs because the elastic material of the elastic sleeve 2, when not subjected to significant force, allows the first flat surface 3 and second flat surface 7 to align, providing sufficient support and maintaining the position of the shaft 4 within the elastic sleeve 2. When the shaft begins to rotate and greater force is applied, the rotational force of the shaft 4 exceeds the temporary fixation capacity of the elastic sleeve 2. At this point, the elastic sleeve 2 is slightly stretched by the shaft 4, causing some deformation. After the elastic sleeve 2 is deformed by force, the restoring force exerts a reverse pressure on the shaft 4. This reverse pressure, generated by the restorative properties of the elastic material, increases the friction between the shaft 4 and the elastic sleeve 2. As friction increases, the movement of the shaft 4 encounters greater resistance, creating a damping effect. This damping effect makes the rotation of the shaft smoother and more controllable, while also improving the operating feel. The design of the base plate 1 and assembly 10 enables the shaft to be stably mounted on the desired structure. The base plate 1 provides stable support, ensuring that the shaft maintains its intended performance during operation. The assembly 10 connects the shaft to other mechanical components, enabling the shaft to function properly within the mechanical system. The key to the entire design is that by adjusting the elastic properties and friction of the elastic sleeve 2, the structure of the rotating shaft is simplified, thereby reducing production costs, while improving the performance and user experience of the rotating shaft. During the manufacturing process, a simple structure is adopted, making the production process of the rotating shaft more efficient and the cost more controllable. The design of the elastic sleeve 2 provides good feedback for the use of the rotating shaft by controlling the friction and damping effects, making the operation smoother. The stable fixing function of the base plate 1 and the assembly 10 ensures the reliability and stability of the entire rotating shaft system, thereby enhancing the applicability and durability of the rotating shaft in various mechanical applications. The utility model not only simplifies the structure, but also realizes an effective damping function through the optimization of the elastic sleeve 2 and friction.This design enables the shaft to smoothly adjust the rotational resistance during rotation, improving the operating feel while also reducing production costs, meeting the needs of modern mechanical systems for efficient, reliable and economical shaft components.
[0024] The elastic sleeve 2 of the present invention serves as a key component, primarily providing damping. To enhance its stability and optimize its damping performance, the sleeve 2 is an extension of the base plate 1, forming an integral structure with the base plate 1. This improves overall structural stability and reliability during operation. The base plate 1, acting as the fixed foundation for the rotating shaft system, effectively enhances its stability through its extended connection to the sleeve 2. This enhanced stability is crucial for preventing unnecessary deformation and displacement of the sleeve 2 during operation, thereby helping to maintain the overall performance and reliability of the rotating shaft. An opening 11 is provided in the middle of the sleeve 2. This opening reduces the overall elasticity of the sleeve 2 and, consequently, the damping force of the rotating shaft. By controlling the elasticity, the damping force can be effectively optimized, ensuring that the damping effect generated by the rotating shaft during operation meets actual requirements. The design of the opening 11 reduces the elasticity of the sleeve 2, thereby adjusting the damping characteristics of the rotating shaft and ensuring more stable operation. When the shaft is working, the design of the opening 11 can also effectively reduce the fluctuation of the friction force between the elastic sleeve 2 and the shaft rod 4, making the damping effect smoother and more controllable.
[0025] In the damping shaft structure, to enhance assembly stability and functionality, the assembly part 10 includes a fixed plate 12, a connecting plate 13, and an assembly plate 14. The arrangement of the fixed plate 12, connecting plate 13, and assembly plate 14 in the shaft system directly impacts the shaft's performance and usability. The fixed plate 12 of the assembly part 10 is fixedly connected to the assembly section 5, making the fixed plate 12 an essential component of the shaft. The function of the fixed plate 12 is to provide a stable connection point, securing the assembly part 10 to the assembly section 5. The fixed plate 12 is connected to the assembly plate 14 via the connecting plate 13. The connecting plate 13 is perpendicular to both the fixed plate 12 and the assembly plate 14, and the fixed plate 12 and the assembly plate 14 are parallel to each other. This connection ensures that the assembly plate 14 and the fixed plate 12 are not in the same plane, i.e., the assembly plate 14 is offset from the fixed plate 12. The offset of the assembly plate 14 from the fixed plate 12 prevents the assembly plate 14 from colliding with the base plate 1 during shaft rotation, thereby avoiding possible interference and damage.
[0026] In the design of the damping shaft, the material selection of the shaft 4 has an important impact on its performance and durability. In order to ensure that the shaft 4 can withstand large mechanical loads and various environmental challenges in long-term use during operation, the material selection of the shaft 4 is crucial. The selection of stainless steel as the material of the shaft 4 is based on the superior properties of stainless steel, including its good mechanical properties, corrosion resistance, and high strength and toughness. Stainless steel is an alloy steel that contains elements such as chromium and nickel, which gives it excellent corrosion resistance. This material can maintain the stability of its structure in a variety of environments, especially in environments with moisture, chemicals or other corrosive media. In the application of the shaft, stainless steel can effectively prevent corrosion or rust caused by environmental factors, thereby maintaining the long-term stability and service life of the shaft 4.
[0027] The assembly section 5 of the utility model is a flat shaft structure, which can reduce the weight of the main shaft and facilitate the fixing and installation of other components. Compared with the traditional round shaft structure, the flat shaft structure demonstrates its superiority in many aspects. The main feature of the flat shaft structure is its flat shape, which makes the cross-section of the shaft wider and can provide a larger contact area in different directions. In the flat shaft structure, by optimizing the material distribution and structural form, the overall mass can be reduced while maintaining the required strength and rigidity. The design of the flat shaft structure also makes the assembly section 5 more convenient when installing other components. In actual applications, the assembly section 5 usually needs to be connected or fixed with other components. The flat shaft structure provides a larger contact surface, which makes the connection with other components more stable and reliable. By providing appropriate fixing holes 8 or interfaces on the flat surface of the flat shaft, efficient coordination and fixation with other components can be achieved.
