Description

Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to a magnetic friction damper. Background Technique

[0002] A damper is a device used to reduce vibration or fluctuation, and is widely used in fields such as engineering, construction, machinery, and aviation. The basic principle of a damper is to dissipate the energy in the vibration system, thereby reducing the amplitude and duration of vibration. Currently, there are friction dampers and magnetic dampers, but both methods have some problems. Since the friction damper dissipates energy through friction, there will be wear due to friction. If the friction part is severely damaged, the friction effect will be reduced. If the damper is severely worn, the durability of the damper will decrease and it is easy to be damaged. The magnetic damper generates a buffering effect through the influence of magnetic force, but the buffering effect generated between magnetic forces cannot be adjusted, resulting in a one-sided magnetic buffering of the damper, reducing the buffering effect of the damper and directly affecting the use effect of the damper.

[0003] Therefore, it is necessary to develop a magnetic friction damper. Content of the Utility Model

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides the following technical solution: A magnetic friction damper, please refer to Figures 1-4 , including a damper 1. A fixed ring 101 is installed on one side of the outer wall of the damper 1. Guide holes 102 are provided above and below the surface of the fixed ring 101. A positive magnetic ring 103 is arranged on one side of the outer wall of the damper 1. A connector A 104 is installed on the other side of the outer wall of the damper 1. A piston rod 2 is installed at one end of the damper 1. A connector B 201 is installed at one end of the piston rod 2. A connector head 202 is installed at one end of the connector B 201. A plug 203 is provided at one end of the piston rod 2. The outer wall of the plug 203 is slidably connected to the inside of the connector head 202. A screw 204 is slidably connected to the inside of the plug 203 and the connector head 202. A nut A 205 is installed above the outer wall of the screw 204. The inner wall of the nut A 205 is threadedly connected to the outer wall above the screw 204. Install the plug 203 at one end of the piston rod 2 on the damper 1, and connect the connector B 201 to the outer wall of the plug 203 in a sliding manner through the connector head 202. The fastening screw 204 penetrates through the connector head 202 and the plug 203 correspondingly, and is locked by the nut A 205 in a threaded connection manner, so as to achieve the installation and fixation of the connector B 201, and at the same time, the connector B 201 can also be disassembled;

[0023] On one side of the outer wall of the piston rod 2, there is a sliding connection with an installation ring 3. Above and below one side of the outer wall of the installation ring 3, there are guide columns 301 installed. The outer wall of the guide column 301 is slidably connected with the inner wall of the guide hole 102. On one side of the outer wall of the guide column 301, there is a nut B302 installed. The inner wall of the nut B302 is threadedly connected with the outer wall of the guide column 301. The installation ring 3 is butted into the guide hole 102 on the fixed ring 101 in a sliding manner by the guide column 301, and the nut B302 is locked in a threaded connection manner, so that the installed nut B302 can limit the guide column 301 to prevent the guide column 301 from detaching from the fixed ring 101. On the other side of the outer wall of the guide column 301, there is a spring 303 installed. The spring 303 is sleeved on the outer wall of the guide column 301. Utilizing the effect of the elastic reaction force of the spring 303, the spring 303 keeps the installation ring 3 in a reset state. At the same time, the nut B302 can be tightened further inward to adjust the installation ring 3. In the center position inside the installation ring 3, there is a sleeve 304 installed. On the inner wall of the sleeve 304, there is a friction sleeve 305 installed. On one side of the outer wall of the sleeve 304, there is a negative magnetic ring 306 installed. The friction sleeve 305 is sleeved on the inner wall of the sleeve 304 on the installation ring 3 and the negative magnetic ring 306 is sleeved on the outer wall. When the piston rod 2 is pressed and contracts inward, it can be dissipated by friction through the friction sleeve 305. During this period, the negative magnetic ring 306 generates a magnetic reaction with the positive magnetic ring 103 on the damper 1, playing a role of magnetic damping. Cooperating with the friction damping, it enhances the damping effect of the damper 1 and also realizes the magnetic friction type functional effect of the damper 1. At the same time, the whole is in a detachable state, which is convenient for disassembling and replacing the friction sleeve 305, and tries to avoid the situation that the effect is affected due to the damage of the friction sleeve 305. By rotating the nut B302, the distance between the negative magnetic ring 306 and the positive magnetic ring 103 can be adjusted, playing a role in changing the damping characteristics to adapt to different working conditions and environmental requirements, and realizing the adjustment of the magnetic damping buffer effect.

[0024] Working principle: When using the present utility model, one end of the piston rod 2 on the damper 1 is installed with a plug 203, and the connecting piece B201 is slidably docked on the outer wall of the plug 203 by the connector 202. The corresponding screw 204 for fastening penetrates through the connector 202 and the plug 203, and is locked by the nut A205 in a threaded connection manner, so as to install and fix the connecting piece B201. At the same time, the connecting piece B201 can also be disassembled. The mounting ring 3 is slidably docked in the guide hole 102 on the fixed ring 101 by the guide post 301, and the nut B302 is locked in a threaded connection manner. After installation, the nut B302 can limit the guide post 301 to prevent the guide post 301 from detaching from the fixed ring 101. A spring 303 is sleeved on the outer wall of the guide post 301. By using the elastic reaction force of the spring 303, the spring 303 keeps the mounting ring 3 in a reset state. At the same time, the nut B302 can be further tightened inward to adjust the mounting ring 3. The inner wall of the sleeve 304 on the mounting ring 3 is sleeved with a friction sleeve 305 and the outer wall is sleeved with a negative magnetic ring 306. When the piston rod 2 is pressed and contracts inward, it can be dissipated by friction through the friction sleeve 305. During this period, a magnetic force reaction occurs between the negative magnetic ring 306 and the positive magnetic ring 103 on the damper 1, playing a role of magnetic damping, cooperating with the friction damping, enhancing the damping effect of the damper 1, and also realizing the magnetic force friction type functional effect of the damper 1. At the same time, the whole is in a detachable state, which is convenient for disassembling and replacing the friction sleeve 305, and tries to avoid the situation that the effect is affected due to the damage of the friction sleeve 305. By rotating the nut B302, the distance between the negative magnetic ring 306 and the positive magnetic ring 103 can be adjusted, playing a role in changing the damping characteristics to adapt to different working conditions and environmental requirements, realizing the adjustment of the magnetic damping buffer effect, and effectively improving the buffer and use effect of the damper.
