Description

Technical Field

[0001] This utility model relates to the field of coupling technology, and more specifically, to a vibration-damping alloy coupling elastomer. Background Technology

[0002] A coupling is a mechanical device used to connect two shafts, enabling them to rotate together to transmit torque. With the advancement of technology, it has been widely used in the aerospace field, playing a crucial role in mechanisms such as aircraft engine mounts.

[0003] Currently, couplings primarily rely on their internal elastic elements to achieve a buffering effect. When various mechanical equipment is in operation, vibration or impact is inevitable due to factors such as motor starting and stopping, uneven load distribution, and interactions between mechanical components. Under such conditions, the elastic element, with its unique physical properties, can sensitively sense and respond to changes in external forces, subsequently undergoing elastic deformation. However, it must be noted that the material properties of the elastic element largely determine its performance in different environments. Especially under prolonged exposure to high temperatures, problems become increasingly apparent, as high temperatures affect the elasticity of the elastic element material. This exposes the equipment to greater vibration and impact risks during operation, accelerating the wear and damage of other components, potentially affecting the overall operational stability, accuracy, and service life of the equipment, and even possibly causing safety accidents, resulting in serious disruption and losses to production operations.

[0004] Therefore, a vibration-damping alloy coupling elastomer is provided to solve the problem of reduced elasticity of the coupling under high-temperature conditions. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vibration damping alloy coupling elastomer that reduces the impact of vibration, improves structural stability, enhances heat dissipation capacity under high temperature environment, and thus slows down the time of material property deterioration.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vibration damping alloy coupling elastomer includes an elastic ring, which is configured as a hollow cylindrical structure. The outer wall of the elastic ring is connected to a plurality of cylindrical elastic columns. Each elastic column has an upper and a lower surface, and a set of grooves is respectively formed on the upper and lower surfaces of the elastic column near the side of the elastic ring.

[0008] The present invention is further configured such that: the axial direction of the elastic ring is the thickness direction of the elastic ring, and the thickness of the elastic column is the same as the thickness of the elastic ring.

[0009] The present invention is further configured such that: the two sets of grooves of any one of the elastic columns are symmetrically opened along half the thickness of the elastic column.

[0010] The present invention is further configured such that the groove is offset from the center of the elastic column.

[0011] By adopting the above technical solution, the elastomer mainly bears the influence of centrifugal force when the drive equipment is running. The center of the groove and connecting groove is pushed away from the center of the elastic ring. The outermost layer of the elastic column is in contact with the half coupling, which is prone to wear. Therefore, the center of the groove and connecting groove is as close as possible to the center of the elastic ring, which can effectively slow down the failure time of the groove and connecting groove and extend the service life of the elastomer.

[0012] The present invention is further configured such that a connecting groove is provided between the two sets of grooves that are coaxial.

[0013] By adopting the above technical solution, the temperature inside the aircraft engine compartment is usually high. Under prolonged high-temperature conditions, the material properties of the elastomer will gradually weaken. Therefore, by opening grooves and connecting slots on the elastomer, the range of compression of the elastomer can be expanded through the grooves and connecting slots when the drive equipment is running, further reducing the impact of vibration and improving structural stability. At the same time, in high-temperature environments, opening more holes can improve the heat dissipation capacity under high-temperature conditions, thereby slowing down the time when the material properties weaken.

[0014] The present invention is further configured such that: two sets of connecting arc surfaces are provided at the connection between the elastic ring and any of the elastic columns.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. Through grooves and connecting slots, the impact of vibration is further reduced, structural stability is improved, heat dissipation capacity under high temperature environment is enhanced, and the time of material property deterioration is slowed down.

[0017] 2. Setting the center of the groove and connecting groove as close as possible to the center of the elastic ring can effectively slow down the failure time of the groove and connecting groove and extend the service life of the elastomer. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] Example 1, please refer to Figure 1-3 The present invention provides the following technical solution:

[0026] Specifically, it refers to a vibration-damping alloy coupling elastomer, see [link / reference]. Figure 1-3 The system includes an elastic ring 1, which is a hollow cylindrical structure. The elastic ring 1 provides a pre-drilled space for the two shaft ends of the driving device and the load device. The outer wall of the elastic ring 1 is connected to multiple sets of cylindrical elastic columns 2. The elastic columns 2 provide buffering for the vibration of the driving device and the load device. The elastic columns 2 have upper and lower surfaces. A set of grooves 21 are respectively opened on the upper and lower surfaces of the elastic column 2 near the side of the elastic ring 1. The axial direction of the elastic ring 1 is the thickness direction of the elastic ring 1. The thickness of the elastic column 2 is the same as the thickness of the elastic ring 1. The two sets of grooves 21 of any elastic column 2 are symmetrically opened along half the thickness of the elastic column 2. The grooves 21 are opened off-center from the center of the elastic column 2. A connecting groove 22 is opened between the two sets of grooves 21 on the same axis. Two sets of connecting arc surfaces 23 are provided at the connection between the elastic ring 1 and any elastic column 2. The two sets of arc surfaces 23 at the connection between any elastic column 2 and the elastic ring 1 are symmetrically arranged along the connecting line between the center of the elastic column 2 and the center of the elastic ring 1. The connecting arc surfaces 23 improve the connection strength between the elastic ring 1 and the elastic column 2.

[0027] Specifically, the vibration-damping alloy coupling comprises an elastomer and two half-couplings whose shapes are adapted to the elastomer. The half-couplings are used to connect to the drive equipment and the load equipment. When the coupling is working, the half-coupling at the drive equipment end transmits power to the elastomer, and the elastomer then transmits the damped power to the half-coupling at the load end, thus realizing power transmission. In this process, the elasticity of the elastomer itself can reduce some of the vibration, which mainly comes from the vibration of the drive equipment during operation. This vibration is negative for the load operation and can easily lead to structural fatigue and damage. Reducing vibration through the material properties of the elastomer can improve the stability of the structure. However, the temperature inside the aircraft engine nacelle is usually high. Under prolonged high-temperature conditions, the material properties of the elastomer will gradually weaken. Therefore, by opening grooves 21 and connecting slots 22 on the elastomer, the range of compression of the elastomer can be expanded through the grooves 21 and connecting slots 22 during the operation of the drive equipment, further reducing the impact of vibration and improving structural stability. At the same time, in high-temperature environments, opening more holes can improve the heat dissipation capacity, thereby slowing down the weakening of material properties. When the drive equipment is running, the elastomer is mainly affected by centrifugal force. If the center of the groove 21 and the connecting groove 22 is moved away from the center of the elastic ring 1, the outermost layer of the elastic column 2 will come into contact with the half coupling and will be prone to wear. Therefore, if the center of the groove 21 and the connecting groove 22 is as close as possible to the center of the elastic ring 1, the failure time of the groove 21 and the connecting groove 22 can be effectively slowed down and the service life of the elastomer can be extended.

[0028] Obviously, the embodiments described above 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 should fall within the protection scope of this utility model.
