Description

Technical Field

[0001] The invention belongs to the technical field of vibration reduction devices, and in particular relates to a wire rope vibration reduction device. Background Art

[0002] The wire rope vibration reduction device, also known as the wire rope vibration damper, is a vibration reduction element. The wire rope vibration reduction device is made of a steel wire rope wound into a spiral shape and fixed between two metal plates. Its stiffness and damping depend on the diameter, number of strands, number of turns, winding method and size of the steel wire rope. It is a new type of vibration reduction device with nonlinear characteristics and dry friction damping. It uses a steel wire rope made of multiple strands of steel wire wound in a certain direction as an elastic element. It has obvious hysteresis characteristics, and its energy dissipation comes from friction, extrusion and slip between steel wires. When the amplitude of the excitation and impact is large enough, internal friction occurs between the strands of the steel wire rope of the vibration reduction device, and it is opposite to the direction of movement of the steel wire rope, thereby consuming a lot of energy and attenuating the vibration and impact intensity. When the amplitude of the vibration is small, the strands of the steel wire rope are twisted together due to friction, and no relative slip occurs, thereby showing good linear elasticity, which helps to maintain the stability of the system. Therefore, the wire rope vibration reduction device is suitable for working conditions with complex and changeable vibration and impact conditions. It has strong adaptive ability and can effectively avoid strong resonance and impact, thus playing the role of buffering and vibration isolation.

[0033] Please also read Figures 1 to 8 , the wire rope vibration reduction device 1 provided in an embodiment of the present invention is described below.

[0034] See also Figure 2 and Figure 5, are schematic diagrams of the structure of a wire rope vibration reduction device 1 and a schematic diagram of the structure of a vibration reduction assembly 20 provided in an embodiment of the present invention, respectively. The embodiment of the present invention provides a wire rope vibration reduction device 1, comprising a moving rod 10, and one or more vibration reduction assemblies 20, wherein a rack 11 is provided at one end of the moving rod 10, and the rack 11 is arranged along the length direction of the moving rod 10; the vibration reduction assembly 20 comprises a gear shaft 21, a fixing plate 22 and a plurality of steel wire ropes 23, the gear shaft 21 comprises a gear body 212 meshing with the rack 11, the fixing plate 22 is arranged at one side of the gear body 212, and is rotatably matched with the gear shaft 21, the fixing plate 22 is used to connect with the fixing unit, one end of the steel wire rope 23 is connected with the fixing plate 22, and the other end is connected with the gear shaft 21, and the plurality of steel wire ropes 23 are distributed along the circumference of the gear shaft 21; when a plurality of vibration reduction assemblies 20 are provided, the plurality of vibration reduction assemblies 20 are arranged at intervals along the length direction of the moving rod 10, and when a single moving rod 10 moves along its own length direction, it can simultaneously match with the gear shafts 21 of the plurality of vibration reduction assemblies 20.

[0035] Compared with the prior art, the wire rope vibration reduction device 1 provided in the embodiment of the present invention has the following beneficial effects:

[0036] The wire rope vibration reduction device 1 provided in the embodiment of the present invention comprises a moving rod 10 and at least one vibration reduction assembly 20. A rack 11 is provided at one end of the moving rod 10. The vibration reduction assembly 20 comprises a gear shaft 21, a fixing plate 22 and a plurality of wire ropes 23. The gear shaft 21 is meshed with the rack 11 for transmission. During the rotation of the gear shaft 21, the wire rope 23 is torsionally deformed, and the initial configuration of the wire rope 23 is changed. The wire ropes 23 entangled with each other generate dry friction between the wires and the strands, thereby consuming energy and playing a role in energy dissipation and vibration reduction. When applied to heavy-duty equipment, the vibration reduction performance of the device can be improved by increasing the number of vibration reduction assemblies 20. Since the moving rod 10 and the vibration reduction assembly 20 adopt the form of gear meshing transmission, a single moving rod 10 can simultaneously drive the gear shafts 21 of multiple vibration reduction assemblies 20 to rotate, thereby achieving the design purpose of jointly reducing the vibration of the device or equipment through multiple vibration reduction assemblies 20, and the vibration reduction performance is excellent. The embodiment of the present invention realizes the vibration reduction function by torsional deformation. When there are multiple vibration reduction assemblies 20, the multiple vibration reduction assemblies 20 are arranged at intervals along the length direction of the moving rod 10, so that the overall structure is compact, the space arrangement is better, and it is convenient to replace the vibration reduction assembly 20 and other parts.

[0037] The working principle of the wire rope vibration reduction device 1 provided by the embodiment of the present invention is as follows: the vibration reduction assembly 20 in the wire rope vibration reduction device 1 provided by the embodiment of the present invention is made of a wire rope 23 wound into a spiral shape and connected between a fixed plate 22 and a gear shaft 21. Its stiffness and damping depend on the diameter, number of strands, number of turns, winding method and size of the wire rope 23. It is a new vibration reduction device with nonlinear characteristics and dry friction damping. The wire rope 23 made of multiple strands of steel wire wound in a certain direction is used as an elastic element, which has obvious hysteresis characteristics, and its energy dissipation comes from friction, extrusion and slip between steel wires. When the amplitude of excitation and impact is large enough, internal friction occurs between the strands of the wire rope 23 of the vibration reduction device, and is opposite to the movement direction of the wire rope 23, thereby consuming a large amount of energy and attenuating vibration and impact intensity. When the amplitude of vibration is small, the strands of the wire rope 23 are twisted together due to friction, and no relative slip occurs, thereby showing good linear elasticity, which helps to maintain the stability of the system. Therefore, the wire rope vibration reduction device 1 is suitable for working conditions with complex and changeable vibration and impact conditions, has strong self-adaptation ability, and can effectively avoid strong resonance and impact, thereby playing a role in buffering and vibration isolation.

[0038] The wire rope vibration reduction device 1 provided in the embodiment of the present invention can be used for vibration reduction of equipment or devices. It not only has a compact and reasonable structural design, but also has the characteristics of excellent vibration reduction performance. It can effectively alleviate the damage of vibration force to equipment or structure, prolong the service life of equipment, improve the stability of equipment operation, and facilitate the replacement of parts, installation and maintenance. Its application scope includes but is not limited to the following aspects: 1. Vibration isolation and buffering of airborne, vehicle-mounted, ship-mounted and other electronic, mechanical equipment and instruments; 2. Basic elastic support of engines and various power machinery; 3. Vibration isolation and buffering of various precision electronic instruments, meters, computers and communication equipment; 4. Safety protection of missile and satellite transportation, navigation and launch systems; 5. Vibration isolation and earthquake resistance of key infrastructure engineering facilities and buildings; 6. Vibration isolation, earthquake resistance and buffering of engineering machinery and general machinery; 7. Vibration isolation and buffering of machinery, electronic equipment and facilities in harsh environments such as high and low temperatures and chemical pollution.

[0039] In the embodiment of the present invention, the moving rod 10 can be a rod-shaped member made of metal or other materials, as long as it has sufficient structural strength. One end of the moving rod 10 is connected to the device or equipment to be damped (such as a vehicle frame), and a rack 11 is formed at the other end, and the rack 11 is meshed with the gear shaft 21 of the damping assembly 20 for transmission. The cross-section of the moving rod 10 can be circular, square or other shapes, and the moving rod 10 can move along its own length. The rack 11 can be obtained by milling teeth directly on the moving rod 10, or it can be fixed to the rod body of the moving rod 10 by screws or welding.

[0040] The vibration reduction assembly 20 includes a gear shaft 21, a fixed plate 22 and a plurality of steel wire ropes 23. The gear shaft 21 can be an integral shaft or assembled from a plurality of parts. The gear shaft 21 is rotatably matched with a fixed plate 22, which is connected to a fixed unit. The fixed unit can ensure that the fixed plate 22 is fixed in position. When the use environment of the wire rope vibration reduction device 1 is relatively clean, the vibration reduction assembly 20 can be exposed and installed in the outside world. At this time, the fixed unit can be a frame or a beam of the device, and the fixed plate 22 can be directly installed on the frame or the beam of the device. When there is dust and oil in the use environment of the wire rope vibration reduction device 1, in order to prevent oil or dust from adhering to the steel wire rope 23 and the gear shaft 21, a closed protective shell can be provided, and the rack 11 and the vibration reduction assembly 20 are accommodated in the protective shell, and one end of the moving rod 10 extends out of the protective shell. At this time, the protective shell is the fixed unit, and the fixed plate 22 is installed on the protective shell.

[0041] The fixing plate 22 is a plate-like component, and its function is to provide a connection position for the wire rope 23, so that one end of the wire rope 23 is fixed, and the other end can rotate with the gear shaft 21. In this way, when vibration or impact is transmitted to the vibration reduction component 20, internal friction occurs between the strands of the wire rope 23, and is opposite to the movement direction of the wire rope 23, thereby consuming a large amount of energy, attenuating the vibration and impact intensity, and achieving the purpose of vibration reduction.

[0042] like Figure 5 , Figure 7 and Figure 8 As shown, the steel wire rope 23 is provided with multiple strands, and the multiple strands of steel wire rope 23 are arranged at intervals along the circumference of the gear shaft 21. The number of steel wire ropes 23 can be set to four strands, six strands, eight strands, or other numbers as needed. Figure 5 , Figure 7 and Figure 8 As shown, the length of the wire rope 23 is greater than the distance between the fixing plate 22 and the gear body 212. After installation, the wire rope 23 has a shape as shown in FIG. Figure 5 The arch shown.

[0043] It should be noted that the vibration reduction performance of the wire rope vibration reduction device 1 is related to factors such as the number of vibration reduction components 20, the number of wire ropes 23, and the model specifications of the wire ropes 23.

When the moving rod 10 moves along its own length direction, the rack 11 can mesh with the gear bodies 212 of the multiple vibration damping assemblies 20 at the same time.
