Example 1
Referring to fig. 1 to 3, the present embodiment provides a damping assembly including a rubber damping structure 2 and a spring damping structure 1, wherein: at least part of the spring vibration damping structure 1 is positioned in the rubber vibration damping structure 2, and the spring vibration damping structure 1 is used for independently supporting a vibrating object and transmitting the vibration part after being reduced to the rubber vibration damping structure 2; the rubber vibration-damping structure 2 serves to absorb vibration energy transmitted to the support.
The spring vibration reduction structure 1 mainly utilizes elastic deformation of a spring to reduce vibration, and the rubber vibration reduction structure 2 mainly utilizes rubber to reduce vibration.
In the damping assembly of the embodiment, the rubber damping structure 2 is used for wrapping at least part of the spring damping structure 1, the spring damping structure 1 is used for independently supporting a vibrating object, firstly, the spring damping structure 1 generates elastic deformation to absorb the vibration energy of the vibrating object and then transmits the vibration energy to the rubber damping structure 2, and the rubber damping structure 2 is used for reducing the vibration transmitted to the supporting object again; the advantage that the good strength of the spring vibration reduction structure 1 supports the vibrating object and the whole vibrating object is not easy to deform and difficult to recover is utilized, so that the vibration of the vibrating object is prevented from being directly transmitted to the rubber vibration reduction structure 2; meanwhile, the advantage of good vibration damping effect of the rubber vibration damping structure 2 is utilized, vibration energy is absorbed before the vibration is transmitted to the support, and the vibration isolation effect is improved.
As an alternative embodiment, referring to fig. 3, the spring damper structure 1 of the present embodiment is located on the central axis of the rubber damper structure 2.
The spring vibration reduction structure 1 is located in a center vibration reduction structure of the vibration reduction assembly, has good elasticity and supporting force after being formed with the rubber vibration reduction assembly, can uniformly transmit vibration to the surrounding rubber vibration reduction structure 2 after being reduced, prevents the rubber vibration reduction structure 2 from being deformed integrally due to nonuniform local stress, and improves the vibration reduction effect.
As an alternative embodiment, referring to fig. 2 and 3, the spring damping structure 1 comprises a spring member 11 and a support member 12 connected, wherein: the spring component 11 is completely wrapped in the rubber vibration damping structure 2, and the supporting component 12 extends out of the rubber vibration damping structure 2 and is used for supporting a vibrator.
The spring component 11 is completely wrapped in the rubber vibration damping structure 2, and can transmit the transverse vibration energy and the longitudinal vibration energy of the vibrating object to the rubber vibration damping structure 2 from the transverse direction and the longitudinal direction after being absorbed (mainly absorbed in the longitudinal direction), so that the vibration damping effect is improved. And through the arrangement of the supporting part 12, the vibration of the vibrating object is transmitted to the spring part 11 from the supporting part 12, and the vibrating object is prevented from directly transmitting the vibration to the rubber vibration damping assembly. As shown in fig. 1 and 3, when the vibrating object vibrates, the support member 12 is compressed, the support member 12 transmits the vibration to the spring member 11, and the elastic deformation of the spring member 11 in the rubber damper structure 2 reduces the vibration.
The spring component 11 can be a compression spring, and the type of the compression spring can be selected to be suitable for vibration reduction on each module of the unit with different weight and rigidity requirements, so that multiple types of application of the same product can be realized, and a good vibration reduction effect can be achieved.
As an alternative embodiment, see fig. 3, the spring element 11 is arranged extending in the vertical direction to absorb vibration energy in the vertical direction of the vibrator.
Specifically, as shown in fig. 3, the number of the spring members 11 is plural, and the plural spring members 11 are arranged at intervals in the horizontal direction.
The number of the spring members 11 in this embodiment is 4 (not limited to this number), and the lengths, elastic coefficients, and the like of the 4 spring members 11 are consistent, and the 4 spring members 11 are elastically deformed by a force, thereby enhancing the supporting and damping effects on the vibrating object. It should be understood that, since the spring member 11 is elastically deformed mainly in the vertical direction, the longitudinal vibration energy of the vibrator is mainly absorbed to reduce the longitudinal transmission of the vibration; the rubber vibration damping assembly completely wraps the spring member 11 and absorbs the transverse vibration energy and the longitudinal vibration energy transmitted, thereby reducing the vibration transmitted to the support.
As an alternative embodiment, referring to fig. 2 and 3, the spring damping structure 1 further includes a first fixing sleeve 13, and the first fixing sleeve 13 is disposed on the periphery of all the spring members 11 for preventing the spring members 11 from being skewed.
The first fixing sleeve 13 may be made of a metal material, and is used for fixing the spring member 11 and preventing the spring member 11 from being inclined when the spring member is subjected to an external force of a vibrating object, and simultaneously, the vibration of the spring member 11 after being reduced can be transversely transmitted to continue the vibration reduction by the rubber vibration reduction structure 2.
As an alternative embodiment, referring to fig. 2 and 3, the supporting member 12 of the present embodiment includes a pressing end 121 and a supporting end 122 for supporting a vibrator, wherein: the pressing end 121 extends into the first sleeve 13 to connect with the free end of the spring member 11, and a sealing portion for preventing the support member 12 from coming off is present at the port of the first sleeve 13.
Specifically, as shown in fig. 2 and 3, the pressing end 121 has an outer diameter larger than that of the supporting end 122 to prevent the supporting member 12 from being removed from the first fixing sleeve 13. The above-described fitting structure of the pressing end 121 and the supporting end 122 serves to transmit the vibration of the vibrating object to the spring member 11 first for vibration damping and provides a good supporting strength.
The sealing part may be a first sealing gasket 5 for sealing the port of the first fixing sleeve 13, the first sealing gasket 5 may be sleeved on the periphery of the supporting member 12, and the first sealing gasket 5 seals the first fixing sleeve 13 while the supporting member 12 and the spring member 11 are mounted in place. The sealing structure can ensure the sealing effect of the spring vibration reduction structure 1, and is suitable for high-efficiency use in various severe environments such as high humidity, high salt fog, high sand dust and the like.
Example 2
In order to further improve the vibration damping effect of the vibration damping assembly in the present embodiment, as an optional implementation manner, a lateral damping structure 3 is present between the spring vibration damping structure 1 and the rubber vibration damping structure 2 in the present embodiment, and the lateral damping structure 3 is located at the periphery of the spring vibration damping structure 1 and is used for absorbing vibration energy in the lateral direction of the spring vibration damping structure 1.
The lateral damping structure 3 can absorb a part of the vibration energy in the lateral direction again after the spring vibration damping structure 1 reduces a part of the vibration transmitted by the vibrating object, and can reduce the vibration again and transmit the vibration to the rubber vibration damping structure 2, thereby improving the vibration damping effect.
The present embodiment provides a specific implementation of a lateral damping structure, as shown in fig. 2 and 3, the lateral damping structure 3 of the present embodiment includes a second fixing sleeve 32 and an elastic sleeve 31, wherein: the second fixing sleeve 32 is located at the periphery of the spring damping structure 1 and is contacted with the rubber damping structure 2, and the elastic sleeve 31 is clamped between the fixing sleeve and the spring damping structure 1.
As shown in fig. 3, the spring member 11 is elastically deformed to reduce a part of vibration, and then is transversely transmitted to the elastic sleeve 31, and after absorbing a part of vibration energy by the elastic sleeve 31, is transmitted to the rubber vibration damping structure 2 by the external second fixing sleeve 32.
Specifically, the elastic sleeve 31 is clamped between the second fixing sleeve 32 and the first fixing sleeve 13, and the elastic sleeve 31 may be made of an elastic material such as rubber.
Besides the above mentioned lateral damping effect, the above mentioned structure of the second fixing sleeve 32 cooperating with the elastic sleeve 31 can prevent the spring damping structure 1 from skewing, and at the same time, the contact area between the spring damping structure 1 and the rubber damping structure 2 can be increased, and the damping effect can be enhanced.
In order to further increase the contact area between the spring damping structure 1 and the rubber damping structure 2 and fully utilize the advantage of good damping effect of the rubber damping structure 2, as an alternative embodiment, referring to fig. 2 and 3, a horizontally extending plate 421 is present at the bottom of the second fixing sleeve 32 for increasing the contact area between the spring damping structure 1 and the rubber damping structure 2.
As shown in fig. 2 and 3, the cuff end of the second pouch 32 is sealed by the second sealing gasket 6, and the second sealing gasket 6 can be sleeved on the periphery of the first pouch 13 (as shown in fig. 2), so that the second pouch 32 is sealed by the second sealing gasket 6 while the first pouch 13 is placed in the rubber sleeve.
As an alternative embodiment, as shown in fig. 2 and 3, the surface of the elastic sleeve 31 presents a spherical protuberance in contact with the inner wall of the second fixed sleeve 32.
The spherical protrusions on the surface of the elastic sleeve 31 enable the elastic sleeve 31 to have better elasticity, gaps exist among the spherical protrusions, the first fixing sleeve 13 and the spring part 11 can be allowed to move in a small range in the second fixing sleeve 32, and compared with the elastic sleeve 31 with a smooth surface, the elastic sleeve 31 can reduce transverse vibration through elastic deformation and displacement in a small range, and has a better vibration reduction effect.
The fitting structure of the second fixing socket 32 and the elastic socket 31 of the present embodiment also has a partial damping effect in the transmission of longitudinal vibration.
Example 3
