The application provides a general type damping mechanism includes: a first shock absorber 10 and a second shock absorber 20, the first shock absorber 10 and the second shock absorber 20 being mirror images; a center shaft 1 connecting a first damper 10 and a second damper 20; wherein each of first shock absorber 10 and second shock absorber 20 includes: the two vibration isolators 11 and 21 are oppositely arranged; and the mounting flange is arranged on the vibration isolation pad and is used for connecting equipment to be subjected to vibration isolation.
First, the structure and operation of first shock absorber 10 and second shock absorber 20 will be explained.
Referring specifically to fig. 1-4, in the illustrated embodiment, the isolators 11 of the first shock absorber 10 and the isolators 21 of the second shock absorber 20 are positioned adjacent and mirror images; the mounting flange 12 of the first vibration damper 10 is provided on the side of the isolator 11 remote from the second vibration damper 20, and the mounting flange 22 of the second vibration damper 20 is provided on the side of the isolator 21 remote from the first vibration damper 10.
The vibration isolators 11 and 21 are made of flexible materials and have certain elasticity. When the shock absorber (the first shock absorber 10 or the second shock absorber 20) is stressed, the vibration isolator can counteract a part of force through the elastic deformation characteristic of the vibration isolator, further reduce the vibration of the equipment to be subjected to vibration isolation mounted on the vibration isolator, and reduce noise.
Alternatively, the vibration insulators 11 and/or 21 are made of rubber. Further, the rubber has high strength, good elasticity, wear resistance and corrosion resistance after being vulcanized.
The mounting flanges 12 and 22 are made of a metallic material to facilitate a secure connection to the equipment to be vibration isolated. At least part of the mounting flange is arranged on the surface of the vibration isolation pad in a protruding mode and is used for contacting equipment to be subjected to vibration isolation. The surface of the mounting flange for contacting the equipment to be vibration isolated can be a plane, and can also be set to be a curved surface or a shape according to the configuration of the equipment to be vibration isolated, and the configuration of the mounting flange is not limited in the application. In addition, the mounting flange and the equipment to be subjected to vibration isolation have a larger contact area, and the mounting stability of the equipment to be subjected to vibration isolation is facilitated.
Alternatively, the mounting flanges 12 and/or 22 are made from 45 steel. The 45 steel is medium carbon structural steel, has good cold and hot workability and excellent mechanical property, and has low price, wide source and easy application.
Optionally, threaded holes are provided on the mounting flange 12 and/or 22, and correspondingly threaded holes or through holes are provided on the equipment to be vibration isolated, so that the mounting flange and the equipment to be vibration isolated can be fastened and connected through screws.
Since the first shock absorber 10 and the second shock absorber 20 are arranged in mirror image and connected together by the center shaft 1, when the universal type vibration damping mechanism shown in fig. 2 is in a normal state, the device to be vibration-isolated can be mounted on the first shock absorber 10, so that the entire universal type vibration damping mechanism is mainly subjected to pressure from above; at the moment, when the equipment to be subjected to vibration isolation operates, force is transmitted to the vibration isolation pad 11 through the mounting flange 12, and the vibration isolation pad 11 deforms and counteracts stress to play a role in damping and reducing noise; meanwhile, the central shaft 1 can further transmit force to the second damper 20, and the first damper 10 is assisted to damp by the deformation of the vibration isolation pad 21; the two dampers work together to enhance the damping and noise reducing effects, and to disperse the force on each damper when the force is transmitted from the first damper 10 to the second damper 20, so that the device to be isolated can be well damped regardless of whether the device to be isolated vibrates in the vertical direction or in the horizontal left-right direction or the horizontal front-back direction.
Because the universal vibration damping mechanism provided by the application has force transmission performance, the rigidity of the whole universal vibration damping mechanism in three directions (vertical direction, horizontal left-right direction and horizontal front-back direction) is basically consistent in the vibration damping process. Wherein, the rigidity of the vibration damping mechanism is related to the deformation degree of the vibration isolation pad under stress. The two vibration isolators 11 and 21 arranged in mirror image are matched, so that the force in all directions can be balanced, and the vibration damping effect is improved.
Further, when the general-purpose vibration damping mechanism shown in fig. 2 is in a hoisting state, the device to be vibration-isolated can be mounted on the second vibration damper 20, so that the whole general-purpose vibration damping mechanism is mainly subjected to a pulling force from below; at the moment, when the equipment to be subjected to vibration isolation operates, force is transmitted to the vibration isolation pad 21 through the mounting flange 22, and the vibration isolation pad 21 deforms and counteracts stress to play a role in damping and reducing noise; at the same time, the center shaft 1 can further transmit force to the first damper 10, and assist the second damper 20 in damping vibration by the deformation of the vibration isolating pad 11. As can be seen from the above, the stiffness of the universal vibration damping mechanism provided by the present application in three directions is substantially the same, and therefore, no matter what the direction of action of force is, under the action of force of the same magnitude, the degree of deformation of the vibration isolator is similar, so that no matter what the installation state of the whole universal vibration damping mechanism is, the universal vibration damping mechanism has excellent vibration damping and noise reducing effects.
In summary, the center shaft 1 has both effects of connecting the first damper 10 and the second damper 20 and transmitting force. To facilitate the installation of the central shaft 1, optionally, mounting holes are provided inside the vibration insulators 11 and 21, and the central shaft 1 is inserted into the two mounting holes 11e and 21 e.
Optionally, the present application provides a damping mechanism of the universal type further comprising a base 30 for mounting the first damper 10 and the second damper 20; each of the first shock absorber 10 and the second shock absorber 20 further includes a connection flange, and the connection flanges 13 and 23 are provided on the vibration isolating pad for connecting the base 30.
Referring specifically to fig. 1 to 4, in the illustrated embodiment, the base 30 includes a bottom plate 31, two sets of support plates 32, and a mounting plate 33, one end of each support plate 32 is connected to the bottom plate 31, and the other end is connected to the mounting plate 33, and the first damper 10 and the second damper 20 are disposed on the mounting plate 33. Wherein the first vibration damper 10 is exposed outside the base 30 to facilitate connection with the equipment to be vibration-isolated, and the second vibration damper 20 is hidden in the base 30; specifically, the two groups of support plates 32 are used for erecting the bottom plate 31 and the mounting plate 33, so that the second damper 20 between the bottom plate 31 and the mounting plate 33 is lifted above the bottom plate 31, the second damper 20 can be protected, the second damper 20 can be separated, and the stress of the whole universal damping mechanism is prevented from being influenced by other external equipment.
Further, the bottom plate 31 and the support plate 32, and/or the mounting plate 33 and the support plate 32 are fastened by screws. In order to better reinforce each plate, the connecting part of the plate can be welded after the screw joint.
Further, the base plate 31 is provided with mounting holes (e.g., screw holes) to facilitate fixing the base plate 31 at a desired position, thereby facilitating mounting the first and second shock absorbers 10 and 20 at a predetermined position.
With continued reference to fig. 1-4, in the illustrated embodiment, the first vibration damper 10 includes a connecting flange 13, the connecting flange 13 is disposed on the vibration isolator 11, and the connecting flange 13 is fixedly connected to the mounting plate 33 to fixedly dispose the first vibration damper 10 on the base 30. The second damper 20 includes a connecting flange 23, the connecting flange 23 is disposed on the vibration isolator 21, and the connecting flange 23 is fixedly connected to the mounting plate 33 so as to fixedly dispose the second damper 20 on the base 30.
Optionally, threaded holes are provided on the connecting flanges 13 and 23, and threaded holes are also provided on the mounting plate 33; when the shock absorber is installed, the threaded hole in the connecting flange 13 or 23 is opposite to the threaded hole in the installing plate 33, and the shock absorber and the base 30 can be tightly connected by bolting in the threaded hole.
In one embodiment, with combined reference to fig. 2 and 4, the connection flanges 13 and 23 are also arranged in mirror image, and when the shock absorber is installed, the threaded holes on the connection flange 13 are simultaneously aligned with the threaded holes on the installation plate 33 and the threaded holes on the connection flange 23; a bolt is simultaneously inserted through the three threaded holes to connect the connecting flange 13, the mounting plate 33 and the connecting flange 23. Further, in the embodiment shown in fig. 2, the tail portion of the bolt passes through the connecting flange 23 and is exposed, and a nut is sleeved on the tail portion, so that the bolt can be further fastened and protected.
Alternatively, the attachment flanges 13 and 23 are made of 45 steel.
To facilitate mounting of the attachment flange 13 or 23 on the vibration isolator 11 or 21, in one embodiment, the vibration isolator 11 or 21 includes: the connecting part is used for arranging a connecting flange; the vibration isolation part has a larger outer diameter as it is closer to the connection part.
Referring to fig. 5 or 6, in the illustrated embodiment, the vibration isolation pad 11 includes a connection portion 11a and a vibration isolation portion 11b, and the vibration isolation portion 11b is disposed above the connection portion 11 a; the vibration-damping pad 21 includes a connecting portion 21a and a vibration-damping portion 21b, and the vibration-damping portion 21b is provided below the connecting portion 21 a; the connecting portions 11a and 21a of the two vibration isolators are adjacent, and the two vibration isolators 11b and 21b are spaced apart by the connecting portions 11a and 21 a; the farther from the connecting portions 11a and 21a, the smaller the outer diameters of the vibration isolating portions 11b and 21b, so that the vibration isolating portions 11b and 21b are substantially truncated cone-shaped. The truncated cone-shaped vibration isolation parts 11b and 21b can be better deformed under force, and the deformation degree of the vibration isolation parts 11b and 21b is only in direct proportion to the magnitude of the force no matter what the action direction of the external force, so that the applicability and the balance of the whole universal vibration attenuation mechanism in different use states are better facilitated. The connecting flanges 13 and 23 are mounted by the connecting parts 11a and 21a, so that the arrangement of the connecting flanges can be prevented from influencing the use effect of the vibration isolation part.
The connecting flange 13 or 23 can be connected to the connecting portion 11a or 21a by means of gluing, screwing, or the like.
In a specific embodiment, the connecting portion 11a or 21a is provided with a slot, and the connecting flange can extend into the slot to connect with the connecting portion.
Referring specifically to fig. 3, in the illustrated embodiment, the outer surface of the connecting portion 11a is provided with a locking groove 11c, and the locking groove 11c is recessed inward compared to the outer surface of the connecting portion 11a and is arranged around the connecting portion 11a in a loop; the connecting flange 13 is provided with a round hole, the connecting part 11a is plugged into the round hole, the hole wall of the round hole is inserted into the clamping groove 11c, and the groove walls on two sides of the clamping groove 11c can clamp the connecting flange 13 tightly. Because the vibration isolating pad 11 is made of a flexible material and has certain elasticity, the distance between the groove walls on the two sides of the clamping groove 11c is smaller than the thickness of the connecting flange 13, and after the hole wall of the round hole extends into the clamping groove 11c, the groove wall of the clamping groove 11c can be squeezed open, so that the two groove walls of the clamping groove 11c have a tendency of being close to each other, and the clamping groove 11c can keep clamping the connecting flange 13.
Similarly, the outer surface of the connecting portion 21a is also provided with a clamping groove 21c, the connecting flange 23 is also provided with a round hole, the connecting portion 21a is plugged into the round hole, the hole wall of the round hole is inserted into the clamping groove 21c, and the groove walls on the two sides of the clamping groove 11c can clamp the connecting flange 23.
Furthermore, at least one groove wall of the clamping groove 11c or 21c is provided with a sinking groove, and the connecting flange can extend into the clamping groove and the sinking groove to be connected with the connecting part.
Referring to fig. 4 to 6, in the illustrated embodiment, the slot 11c includes an upper slot wall and a lower slot wall, a sunken slot 11d is formed on the lower slot wall of the slot 11c, and a step is formed between the sunken slot 11d and the outer surface of the connecting portion 11 a. The connecting flange 13 is provided with an extension part 13a, and the extension part 13a is arranged on the lower surface of the connecting flange 13 around the circular hole; after the hole wall of the round hole extends into the clamping groove 11c, the extending part 13a extends into the sinking groove 11 d. The arrangement of the sinking groove 11d can increase the contact area between the connecting flange 13 and the connecting part 21a, thereby increasing the friction force between the connecting flange and the connecting part and being beneficial to the stability of connection between the connecting flange and the connecting part; on the other hand, the step between the sunken groove 11d and the outer surface of the connecting portion 11a can abut against the extending portion 13a, which is more beneficial to maintain the connection state of the connecting flange 13 and the connecting portion 21 a.
Similarly, in the embodiment shown in fig. 4 to 6, the slot 21c also includes an upper slot wall and a lower slot wall, a sunken slot 21d is formed on the upper slot wall of the slot 21c, and a step is formed between the sunken slot 21d and the outer surface of the connecting portion 21 a. The connecting flange 23 is provided with an extension part 23a, and the extension part 23a is arranged on the upper surface of the connecting flange 23 around the circular hole; after the hole wall of the round hole extends into the clamping groove 21c, the extending part 23a extends into the sinking groove 21d, and the step between the sinking groove 21d and the outer surface of the connecting part 21a can abut against the extending part 23 a.
Alternatively, the surface of the vibration isolation portions 11b/21b is a slope, and the slope of the slope is 1.
As can be seen from the above, the vibration isolation portions 11b and 21b have a circular truncated cone shape. Therefore, it is easy to understand that the surfaces of the vibration insulating portions 11b and 21b are inclined surfaces. In the embodiment shown in fig. 2, the bevel is angled at 45 ° to the horizontal. At this angle, the stiffness of the damper is substantially constant; at this time, when the shock absorber is stressed, the ratio of force to displacement of the vibration isolation part in unit area is a constant value, which is beneficial to stabilizing the balance point of the shock absorber and improving the shock absorption performance.
Optionally, the mounting flange 12 or 22 includes: the mounting part is convexly arranged outside the vibration isolation pad and is used for connecting equipment to be subjected to vibration isolation; the extension part is arranged in the vibration isolation pad; a through hole penetrating the mounting part and the extension part; the through holes 12c and 22c of the two mounting flanges 12 and 22 are communicated, and the central shaft 1 penetrates through the two through holes.
Referring to fig. 3 or fig. 4, in the illustrated embodiment, a mounting hole 11e is formed in the vibration isolation pad 11, and the mounting hole 11e penetrates through the vibration isolation pad 11 in the vertical direction; the vibration insulator 21 is provided with a mounting hole 21e therein, and the mounting hole 21e penetrates the vibration insulator 21 in the vertical direction. The mounting flange 12 comprises a mounting part 12a and an extension part 12b, one end of the extension part 12b is provided with the mounting part 12a, and the other end of the extension part 12b extends into the mounting hole 11 e; the mounting flange 22 comprises a mounting part 22a and an extension part 22b, one end of the extension part 22b is provided with the mounting part 22a, and the other end of the extension part extends into the mounting hole 21 e; the two extensions 12b and 22b can contact each other through the mounting holes 11e and 21e so that the through holes 12c and 22c communicate. Due to the two extensions 12b and 22b abutting each other, when a force is applied to one of the mounting portions 12a or 22a during use, the force can be quickly transmitted to the other extension 22b or 12b along the extension 12b or 22 b. Since the central shaft 1 is inserted into the two through holes 12c and 22c, the extending portions 12b and 22b can define the installation position of the central shaft 1 and stabilize the central shaft 1, which facilitates the connection of the central shaft 1 to the two dampers and also facilitates the transmission of force.
Referring to fig. 1 in combination, in the illustrated embodiment, the mounting portions 12a and 22a are generally disk-shaped with the surfaces thereof remote from the vibration isolators 11 and 21 being planar to facilitate connection with equipment to be vibration isolated. Optionally, mounting holes (e.g., threaded holes) are provided in the mounting portions 12a and 22a to facilitate vibration isolation of the device.
Due to the mirror image arrangement of the two mounting flanges 12 and 22, the equipment to be subjected to vibration isolation can be mounted on the mounting flange 12 and the mounting flange 22, the equipment can be freely selected according to actual mounting requirements, and the mounting mode is simple, convenient and easy to operate when the mounting mode needs to be replaced.
In one embodiment, the through holes 12c and 22c are common through holes, and the central shaft 1 is in interference fit with the through holes 12c or 22c, and the connection and force transmission are realized through the friction force between the two.
In another embodiment, an internal thread is arranged in the through hole, and an external thread is arranged on the surface of the central shaft 1; the central shaft 1 can be screwed to the through-hole by means of internal and external threads.
In this embodiment, the central shaft 1 is screwed to two dampers. Specifically, internal threads are arranged in the through holes 12c and 22c, and the central shaft 1 is a screw rod; one end of the screw rod is inserted into one of the through holes 12c or 22c, and the screw rod is continuously rotated, so that the screw rod can extend into the other through hole 22c or 12c, and the two mounting flanges 12 and 22 are connected. The connection between the central shaft 1 and the mounting flanges 12 and 22 can be fastened through a threaded connection mode, and meanwhile, the central shaft 1 is in close contact with the mounting flanges 12 and 22, and stress and force transmission are easier, so that the balance of the whole universal type vibration damping mechanism is facilitated.
Alternatively, the length of the center shaft 1 is larger than the total length of the through holes 12c and 22c, and therefore, the center shaft 1 can pass through the two through holes 12c and 22 c. Referring to fig. 1 or 2, in the embodiment shown, the upper end of the central shaft 1 protrudes from the through hole 12 c; the lower end of the central shaft 1 is provided with a disc so as to facilitate manual rotation of the central shaft 1; after rotating the central shaft 1 to the extreme position, the disc at the lower end of the central shaft 1 abuts against the mounting flange 22, which can define the second damper 20. At this time, the surface of the central shaft 1 protruding out of the through hole 12c is also provided with an external thread which can be used for connecting with a threaded hole on equipment to be subjected to vibration isolation; therefore, when the vibration isolation equipment runs and generates vibration, the force can be directly transmitted to the central shaft 1 and can be transmitted to the two vibration absorbers through the central shaft 1, and the balance of the whole universal vibration attenuation mechanism is better.
Optionally, each of the first shock absorber 10 and the second shock absorber 20 further includes a support frame, and the support frame is disposed in the vibration isolator.
Wherein, the supporting framework is made of metal material; alternatively, the support frame is prepared using 45 steel.
The supporting framework is wrapped in the vibration isolator, so that the deformation of the vibration isolator can not be influenced, the structure of the vibration isolator can be strengthened, the stability of the structure of the vibration isolator can be facilitated, and the vibration isolator can effectively play a role in damping and reducing noise. Meanwhile, the design of the supporting framework can also avoid the deformation of the vibration isolation pad, and the service life of the vibration isolation pad is prolonged. In addition, the supporting framework can better transmit and disperse force, and the balance of the whole universal type vibration damping mechanism is facilitated.
