Description

Technical Field

[0001] This utility model relates to the field of viscous damper technology, and in particular to a damping device for rotating components. Background Technology

[0002] Dampers are general-purpose devices used for industrial vibration reduction, and their application is becoming increasingly widespread in various industries where vibration reduction is required. Rotational damping is a crucial area of ​​damper operation. Many types of damping devices are used for rotating components, but currently, friction damping is the primary method used for this purpose, effectively reducing vibrations in rotating parts. Friction damping devices are vibration reduction devices attached to a structure. They dissipate vibration energy through sliding friction, effectively reducing vibration and energy consumption. Therefore, friction dampers, with their advantages of simple structure, strong vibration reduction capacity, and relatively low cost, are widely used in vibration reduction of rotating components.

[0003] However, this friction damping method has some drawbacks. This is because the friction damping between the friction damper and the rotating component generates a lot of heat. The high temperature generated between the friction damper and the rotating component may have an adverse effect on the rotating component and affect its normal operation. Moreover, the friction damping method causes greater damage to the flexible friction element, resulting in a shorter service life of the flexible friction element. After long-term use, it is easy to cause vibration of the rotating component. Utility Model Content

[0004] To address the technical problems of existing friction damping methods generating high heat, affecting the normal operation of rotating components, and causing significant damage to flexible friction elements, which can easily lead to vibration of rotating components after prolonged use, this utility model provides the following technical solution.

[0005] This utility model discloses a damping device for a rotating component, comprising a housing and a base connected to the lower end of the housing. The housing contains damping fluid, and a sealing body is provided at the center of the upper part of the housing. A rotating shaft is rotatably connected to the center of the upper part of the housing, and a damping plate is fixedly connected to the lower end of the rotating shaft. A plurality of damping elements are fixedly connected to the lower part of the damping plate and arranged radially along the damping plate. A plurality of fixing elements are fixedly provided on the upper part of the base and are arranged alternately with the damping elements.

[0006] As a further technical solution, the damping element is a plurality of damping rods arranged along the circumferential direction of the damping plate.

[0007] As a further technical solution, the fixing element is a plurality of fixing rods fixed in the circumferential direction on the upper part of the base.

[0008] As a further technical solution, the damping element is a damping ring arranged along the circumferential direction of the damping plate.

[0009] As a further technical solution, the fixing member is a fixing ring fixed in the circumferential direction on the upper part of the base.

[0010] As a further technical solution, a screw plug is provided on one side of the upper part of the housing, and the screw plug is used for injecting the damping fluid.

[0011] As a further technical solution, the damping plate has a disc-shaped structure.

[0012] The beneficial effects of this invention are as follows: The rotating shaft of this invention is connected to a damping plate located inside the housing and multiple damping components located below the damping plate. Multiple fixing components are fixedly installed inside the housing, which is also filled with damping fluid. Within the damping fluid, the fixing components exert resistance on the rotating shaft and the rotating damping components, thereby reducing the speed of the rotating shaft through the damping components and the damping plate, thus achieving the function of damping and vibration reduction. Therefore, by changing the original friction damping to a high-viscosity liquid damping method, the wear of the damping components is completely eliminated, the high temperature generated by friction is reduced, and the service life of the damper and rotating parts is improved. Furthermore, the use of liquid damping avoids the problem of vibration in the rotating parts, effectively reducing vibration in the rotating parts. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] like Figure 1 and Figure 2 As shown, this utility model discloses a damping device for rotating components, comprising a housing 1 and a base 7 connected to the lower end of the housing 1. The base 7 has a disc-shaped structure, and the housing 1 has a hollow structure. The housing 1 is fixedly connected to the upper part of the base 7, and the housing 1 contains damping fluid 2. The high-viscosity damping fluid 2 is used to provide viscous force for vibration reduction of the rotating components. Specifically, a screw plug 9 is provided on one side of the upper part of the housing 1. By opening the screw plug 9, the damping fluid 2 can be injected into the housing 1.

[0019] In a preferred embodiment, a sealing body 8 is provided at the upper center of the housing 1, and a rotating shaft 3 is rotatably connected to the upper center of the housing 1. The sealing body 8 is used to seal the outer wall of the rotating shaft 3. A damping plate 4 is fixedly connected to the lower end of the rotating shaft 3. The damping plate 4 extends into the damping fluid 2. In this embodiment, the damping plate 4 has a disc-shaped structure and rotates with the rotating shaft 3. Of course, the damping plate 4 can also be a cube or other plate structure. This utility model does not make any particular limitation on it.

[0020] A plurality of damping elements 5 are fixedly connected to the lower part of the damping plate 4 and arranged radially along the damping plate 4. A plurality of fixing elements 6 are fixedly provided on the upper part of the base 7 and are arranged interlaced with the damping elements 5. The damping elements 5 can rotate with the damping plate 4 and the rotating shaft 3. When the damping elements 5 rotate in the damping fluid 2, the fixing elements 6 can increase the damping force of the damping fluid 2, thereby effectively damping and reducing the vibration of the damping elements 5, and thus reducing the vibration of the rotating shaft 3.

[0021] In a preferred embodiment, the damping element 5 consists of a plurality of damping rods arranged along the circumference of the damping plate 4, with the multiple damping rods surrounding the center of the damping plate 4. In this embodiment, one damping element 5 refers to a ring structure composed of multiple damping rods. Of course, the damping element 5 is not limited to being composed of multiple damping rods; it can also be composed of multiple vertical plate-like structures, or the damping element 5 can be a ring structure. For example, the damping element 5 can be a damping ring arranged along the circumference of the damping plate 4. In this case, the fixing element 6 is a fixing ring fixed to the upper circumference of the base 7. The fixing element 6 can also work with the damping fluid 2 to generate a damping effect on the damping element 5, thereby reducing the vibration of the rotating shaft 3. The present invention does not particularly limit the specific shape of either component.

[0022] Similarly, the fixing member 6 is a number of fixing rods fixed in the circumferential direction on the upper part of the base 7. One fixing member 6 refers to a ring structure composed of multiple fixing rods. In this embodiment, each damping member 5 and the fixing member 6 are staggered in the radial direction of the damping plate 4, which can effectively dampen and reduce the vibration of the damping member 5 and reduce the vibration of the rotating shaft 3.

[0023] The working principle of this utility model is as follows: During installation, the lower end of the rotating shaft 3 is fixedly connected to the damping plate 4, the upper end of the rotating shaft 3 is inserted into the housing 1, and the rotating shaft 3 and the housing 1 are sealed by the sealing body 8. Then, the housing 1 is fitted onto the stop part of the base 7 and connected. Finally, the damping fluid 2 is injected into the cavity formed by the housing 1 and the base 7 through the screw plug 9.

[0024] During operation, when the rotating shaft 3 rotates at high speed, it drives multiple damping components 5 to rotate together through the damping plate 4. Meanwhile, the fixed components 6, which are staggered with each damping component 5, remain stationary. At this time, each rotating damping component 5 will drive the damping fluid 2 to generate a rotational force, while the fixed components 6 remain stationary and generate a damping force on the damping fluid 2. Therefore, through the high viscosity characteristics of the damping fluid 2, the fixed components 6 will generate resistance to the rotating damping components 5, and through the damping components 5 and the damping plate 4, the vibration and speed of the rotating shaft 3 will be reduced, thus completing the damping and vibration reduction function.

[0025] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
