A high-frequency folded thin-walled tube vibration damper

Abstract

This invention discloses a high-frequency folded thin-walled tube vibration damper. The damper includes: a folded thin-walled tube, which is composed of multiple U-shaped tubes with U-shaped cross-sections welded coaxially in sequence; and assembly ports located at both ends of the folded thin-walled tube. Each assembly port consists of a welding plate and a fixing stud. The welding plate is encapsulated at the end of the folded thin-walled tube, forming a sealed cavity inside the tube. The fixing stud is vertically positioned at the center of the welding plate surface. This vibration damper uses a folded thin-walled tube, made by multiple layers of U-shaped tubes and multiple precision welding processes, as the supporting vibration damping structure. Its thin wall and the formed sealed cavity effectively reduce the vibration propagation path and provide vibration damping. It also exhibits excellent fatigue resistance, meeting the vibration damping requirements of high-frequency vibrating equipment such as motors.

Description

Technical Field

[0001] This invention relates to the field of vibration damper technology, and specifically to a high-frequency folded thin-walled tube vibration damper. Background Technology

[0002] Electric motors are widely used, and prolonged high-speed operation often leads to severe bearing wear. High-frequency vibrations can also affect the operating status and safety of other equipment near the motor. Reducing or blocking the propagation path of high-frequency vibrations is a key issue, and rubber vibration dampers are commonly used for isolation. However, under heavy loads, the vibration damping performance of compressed rubber is insufficient. Therefore, a high-frequency folded thin-walled tube vibration damper has been designed to effectively reduce the vibration propagation path while also providing vibration damping, potentially solving this problem. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a folded thin-walled tube vibration damper suitable for suppressing high-frequency vibrations.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] A high-frequency folded thin-walled tube vibration damper, the vibration damper comprising:

[0006] A folded thin-walled tube, wherein the folded thin-walled tube is composed of multiple U-shaped tubes with U-shaped cross-sections welded together coaxially;

[0007] The assembly ports are located at both ends of the folded thin-walled tube. The assembly ports consist of welding plates and fixing studs. The welding plates are encapsulated at the ends of the folded thin-walled tube, forming a sealed cavity inside the folded thin-walled tube. The fixing studs are vertically positioned at the center of the surface of the welding plates.

[0008] A further improvement is that the folded thin-walled tube and the assembly port are integral structures welded from the same material.

[0009] A further improvement is that the folded thin-walled tube and the assembly port are made of stainless steel, aluminum alloy, copper alloy or titanium alloy.

[0010] A further improvement is that the diameter of the circle containing the valley peak and valley bottom of the U-shaped tube is 30-200mm, and the diameter ratio is 1.1-2.

[0011] A further improvement is that the wall thickness of the U-shaped tube is 0.2-2mm.

[0012] A further improvement is that the outer diameter of the welding plate is the same as the outer diameter of the end of the folded thin-walled tube.

[0013] A further improvement is that the diameter of the fixing stud is M3-M20.

[0014] A further improvement is that the folded thin-walled tube is a single folded thin-walled tube or multiple folded thin-walled tubes nested from the inside out in an assembly structure, and the ratio of the average diameter of the outer folded thin-walled tube to the average diameter of the inner folded thin-walled tube in adjacent folded thin-walled tubes is not less than 1.5.

[0015] The beneficial effects of the present invention are as follows: the vibration damper uses a folded thin-walled tube made of multiple stacked U-shaped tubes and multiple precision welding as the supporting vibration damping structure. Its wall is thin and a sealed cavity is formed inside, which can effectively reduce the vibration propagation path and has a vibration damping effect. At the same time, it has outstanding fatigue resistance and can meet the vibration damping requirements of high-frequency vibration equipment such as motors. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Combination Figure 1 and Figure 2 As shown, a high-frequency folded thin-walled tube vibration damper includes:

[0021] Folded thin-walled tube 1 is composed of multiple U-shaped tubes 11 with U-shaped cross-sections welded together in sequence.

[0022] The assembly ports 2 are located at both ends of the folded thin-walled tube 1. The assembly ports 2 consist of a welding plate 21 and a fixing stud 22. The welding plate 21 is encapsulated at the end of the folded thin-walled tube 1, so that a sealed cavity is formed inside the folded thin-walled tube 1. The fixing stud 22 is vertically set at the center of the surface of the welding plate 21.

[0023] The vibration damper uses a folded thin-walled tube 1 made of multiple stacked U-shaped tubes 11 through multiple precision welding processes as the supporting vibration damping structure. Its thin wall and sealed cavity inside can effectively reduce the vibration propagation path and have a vibration damping effect. At the same time, it has excellent fatigue resistance and can meet the vibration damping requirements of high-frequency vibration equipment such as motors.

[0024] Preferably, in this invention, the folded thin-walled tube 1 and the assembly port 2 are integral structures welded from the same material. The specific material can be stainless steel, aluminum alloy, copper alloy, or titanium alloy, etc.

[0025] Preferably, in this invention, each U-shaped tube 11 is a two-half spliced ​​and welded structure. The diameter of the circle containing the peak and the bottom of the U-shaped tube 11 is 30-200mm, and the diameter ratio is 1.1-2. For example, the diameter of the circle containing the peak is 120mm, and the diameter of the circle containing the bottom is 80mm.

[0026] Preferably, the wall thickness of the U-shaped tube 11 in this invention is 0.2-2mm, for example, 0.2mm, 0.5mm, 1mm, 2mm, etc. Although the wall thickness is small, its fatigue resistance is outstanding under the action of the sealed cavity.

[0027] Preferably, in this invention, the outer diameter of the welding plate 21 is the same as the end outer diameter of the folded thin-walled tube 1.

[0028] Preferably, the diameter of the fixing stud 22 in this invention is M3-M20.

[0029] Preferably, in this invention, the folded thin-walled tube 1 is a single folded thin-walled tube 1 or multiple folded thin-walled tubes 1 nested assembly structure from the inside to the outside, and the ratio of the average diameter of the outer folded thin-walled tube 1 to the inner folded thin-walled tube 1 in adjacent folded thin-walled tubes 1 is not less than 1.5. The folded thin-walled tube 1 of the nested assembly structure supports a greater weight and has better mechanical properties. In actual use, it can be assembled according to specific needs.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
