Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of damping sheets, in particular to a damping sheet for a twisting machine with a surface dematerialized and processed friction texture. Background Art
[0002] At present, the domestic products on the market are mainly damping plates with no friction patterns and those with mold-embossed friction patterns. Damping plates with no friction patterns are similar to ordinary gaskets and cannot effectively achieve stable friction damping functions. They cannot play their due role in scenarios where damping is required for stable operation. Damping plates with mold-embossed friction patterns, although they have a friction pattern design, have reduced friction due to the influence of surface release agents, thereby weakening the damping effect that the friction patterns should have. As a result, in actual applications, it is difficult for both types of damping plates to obtain stable rotation speeds. In addition, traditional damping plates also have the defects of easy wear and corrosion resistance. In actual use, their service life is mostly only 1-3 months before various failure conditions will occur. This requires frequent inspection and replacement operations, which greatly reduces the actual use value and comprehensive performance of the damping plates.
[0003] Therefore, there is an urgent need to improve the damping plate of the twisting machine with surface dematerialization and friction texture to solve the above-mentioned problems. Utility Model Content

[0021] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0022] like Figure 1-Figure 3As shown, the damping plate of the double twister with surface dematerialization and friction texture provided by this embodiment has a through hole 2 at the axis center position of the damping plate 1, and a friction texture 3 for friction is provided on the outer surface of the damping plate 1. The texture area of the friction texture 3 is the entire area of the front and back sides of the damping plate 1. The through hole 2 at the axis center position of the damping plate 1 facilitates its installation on the corresponding shaft component to achieve precise positioning and stable assembly, ensuring that the damping plate 1 can rotate with the shaft and play a role during the operation of the equipment, and the friction texture 3 for friction is provided on the outer surface of the damping plate 1, and the texture area covers the front and back sides of the damping plate 1. The entire surface area or a part of the area, the entire single surface area or a part of the area, can significantly increase the friction between the damping plate 1 and the contact parts, and can effectively provide a stable friction damping effect when the double twister and other equipment are running, avoiding the situation of unstable speed; compared with the traditional damping plate 1, it can better adapt to the work requirements, whether in the process of starting, running or stopping, it can ensure the stability and reliability of the equipment operation through reliable friction control, reduce equipment failures and efficiency reduction caused by insufficient or unstable damping, and improve the overall performance and work quality of the equipment.
[0023] Further, such as Figure 1-Figure 3 As shown, the static friction coefficient of the friction texture 3 is 0.01-0.03, and the dynamic friction coefficient of the friction texture 3 is 0.005-0.01. The static friction coefficient of the friction texture 3 of 0.01-0.03 can make it relatively easy for the damping plate 1 to overcome the static resistance and enter the motion state in the initial state, reducing energy loss and jamming during startup; and the dynamic friction coefficient is 0.005-0.01, so that the damping plate 1 can maintain a small friction force during movement, which can effectively provide a certain damping effect to stabilize the rotation speed, and will not cause excessive energy consumption or excessive wear of components due to excessive friction, thereby ensuring the stability and efficiency of the equipment operation, extending the service life of the equipment, and enabling equipment such as the twisting machine to operate more stably and reliably during operation, thereby improving production efficiency and product quality.
[0024] Further, such as Figure 1-Figure 3As shown, the surface texture roughness of the damping plate 1 is Ra10-30, and the material of the damping plate 1 is one of polyurethane MDI, TDI, NDI and PTMG, and the hardness of the damping plate 1 is 70-90 degrees. The surface texture roughness of the damping plate 1 is Ra10-30, which helps to avoid excessive wear and energy loss while ensuring a certain friction force; the material of the damping plate 1 is one of polyurethane MDI, TDI, NDI and PTMG, which has good wear resistance, elasticity and corrosion resistance, and can adapt to different working environments; and the hardness of the damping plate 1 is 70-90 degrees, which makes it have a certain rigidity to withstand working pressure and appropriate elasticity to buffer and adapt to deformation, so that the damping plate 1 can work stably under various working conditions, effectively provide damping effect, ensure the smoothness and reliability of equipment operation, extend the service life of the equipment, and improve the overall performance and working efficiency of the equipment.
[0025] Further, such as Figure 1-Figure 3 As shown, the outer diameter of the damping plate 1 is 24.5+ / -0.5, the inner diameter is 13.6+ / -0.1 and the thickness is 3-4+ / -0.1. The damping plate 1 can achieve stable installation and good concentricity by designing precise dimensions, ensuring that there will be no deviation or shaking during operation. The specific thickness range affects the elasticity and damping performance of the damping plate 1, so that it can provide appropriate friction and buffering effect during work, thereby ensuring the smoothness and reliability of the equipment operation.
[0026] like Figure 1-Figure 3 As shown, the principle of the two-for-one twister damping plate with surface dematerialization and friction texture provided in this embodiment is as follows:
[0027] The surface texture changes the surface friction coefficient of the softer elastic material, thereby generating damping, so as to achieve a stable speed. It can also be called various names such as friction plate.
[0028] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
[0029] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.
[0030] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
