Description

Technical Field

[0001] This invention belongs to the field of vibration damping and correction accessories, specifically referring to an external fluid-type vibration damping and correction structure. Background Technology

[0002] In modern life and production, many mechanical devices achieve their function by rotating rotating structures, such as car wheels, train wheels, and lathe chucks. However, in actual production, the weight distribution of the rotating structure is not uniform, causing a slight deviation between its center of gravity and the center of the circle. At low speeds, this deviation is not a significant problem, but at higher speeds, the rotating structure generates noticeable vibrations. Wheel vibration not only causes considerable noise and affects vehicle stability, posing safety hazards, but also increases energy consumption during rotation. Similarly, chuck vibration not only increases energy consumption during rotation but also significantly impacts the machining of workpieces fixed on the chuck, severely limiting machining accuracy and hindering industry progress.

[0003] To overcome the above problems, we have developed an external vibration damping and correction system (patent number ZL202122104256.5), which can effectively match existing rotating structures, effectively prevent or reduce the vibration generated when the rotating structure rotates, greatly reduce the noise during product use, and improve the energy conversion effect, product safety, stability and rotation accuracy, effectively promoting the development of the industry.

[0004] However, in practical applications, we have found that the counterweight ball in the above-mentioned patent will slide in the groove at a high frequency and frequently collide with the inner wall of the groove, which will cause wear or deformation of the inner wall of the groove and the counterweight ball, and ultimately reduce the product's performance after a period of time. Summary of the Invention

[0009] Furthermore, the vibration damping and correction device consists of a vibration damping and correction device body, a fluid tank disposed within the vibration damping and correction device body, and a sealing cover that cooperates with the fluid tank.

[0010] Preferably, the vibration damping and correction device body is also provided with a mounting groove that communicates with the fluid channel, and the diameter of the mounting groove is larger than that of the fluid channel.

[0011] Preferably, the upper section of the inner wall of the mounting groove is provided with an internal thread, the bottom of the mounting groove is provided with an inner sealing groove for placing a sealing ring, an annular lower limiting ring is provided at the position where the inner sealing groove contacts the fluid groove, and the bottom of the mounting groove is also provided with an outer sealing groove whose inner side is connected to the inner sealing groove.

[0012] Preferably, the bottom of the outer sealing groove is arc-shaped, and an inwardly protruding ring is provided on the outer side wall of the outer sealing groove; the horizontal centerline of the protruding ring and the centerline of the sealing ring are located in the same plane.

[0013] Preferably, the sealing cap consists of a sealing cap body, a sealing cap boss located on the upper section of the outer side wall of the sealing cap body and protruding outward, a semi-circular groove located on the lower side of the sealing cap body, a spring fitted on the outer side of the sealing cap body, a sealing ring fitted on the outer side of the sealing cap body and in contact with the spring, and an upper limit ring located on the lower side of the sealing cap body and cooperating with the lower limit ring.

[0014] Preferably, the bottom of the fluid groove is semi-circular, and the diameter of the semi-circle is the same as the inner diameter of the fluid groove, and the radius of the semi-circular groove is the same as the inner diameter of the fluid groove; the outer wall of the sealing cover boss is provided with an external thread that matches the internal thread on the mounting groove.

[0015] As another preferred embodiment, the vibration damping and correction device comprises an upper housing, a lower housing that cooperates with the upper housing, four fixing holes respectively disposed at the four corners of the upper housing and the lower housing and cooperating with each other, an upper fluid channel disposed on the lower side of the upper housing, a lower fluid channel disposed on the upper side of the lower housing and cooperating with the upper fluid channel, and sealing structures respectively disposed on the upper housing and the lower housing and cooperating with each other; the upper housing and the lower housing cooperate to form the main body of the vibration damping and correction device; the upper fluid channel and the lower fluid channel cooperate to form a fluid channel.

[0016] Preferably, the sealing structure comprises a lower sealing groove surrounding the lower fluid groove and disposed on the lower housing, an upper sealing groove surrounding the upper fluid groove and disposed on the upper housing, an annular sealing ring disposed between the lower sealing groove and the upper sealing groove, a deformable socket disposed on the outer edge of the lower sealing groove, and a deformable plug disposed on the outer edge of the upper sealing groove and cooperating with the deformable socket.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] (1) The selection of the fluid counterweight in this invention needs to be based on actual needs. The greater the required correction force, the greater the density of the selected fluid counterweight, and vice versa. This greatly improves the applicability and flexibility of the product.

[0019] (2) The part of the fluid tank in the present invention that is not filled with fluid counterweight needs to be filled with a specific filling gas according to the actual situation. It is necessary to ensure that the filling gas does not react with the material it is in contact with. When necessary, a vacuum operation can also be performed on it.

[0020] (3) The present invention is provided with a convex ring, the purpose of which is to make the middle part of the sealing ring protrude towards the sealing ring after the bottom end of the sealing ring is inserted into the outer sealing groove, and then when it is subjected to the downward pressure of the spring, the convex part undergoes directional deformation, thereby enabling it to be tightly pressed onto the sealing ring, further ensuring that the sealing ring can be pressed inward, thereby improving the sealing effect of the sealing ring.

[0021] (4) The upper limit ring and the lower limit ring of the present invention cooperate with each other to better limit the sealing ring and prevent the sealing ring from falling into the fluid groove due to the pressure of the sealing ring.

[0022] (5) As the sealing cap is tightened, the spring will gradually contract, thereby gradually increasing its elastic force. The increased elastic force of the spring will press down on the sealing ring. Under the action of the spring pressure, the sealing ring will deform inward at the position of the convex ring, and finally the deformed part of the sealing ring will press the sealing ring inward, effectively improving the sealing effect of the product and ensuring that the fluid counterweight will not leak out.

[0023] (6) The present invention has a second sealing structure. After the upper box and the lower box are fastened together, the deformable plug will be inserted into the deformable socket. The deformable plug will then occupy the space of the outer edge of the lower sealing groove, thereby making the deformable plug contact the outer side of the annular sealing ring and exert inward pressure on the annular sealing ring. Under the pressure of the deformable plug, the annular sealing ring will deform inward. After deformation, the annular sealing ring will effectively fill the inner contact position of the upper sealing groove and the lower sealing groove, thereby better completing the filling of the gap, further ensuring the sealing effect of the product, avoiding the leakage of fluid counterweight which would cause the product performance to decrease or even fail, and effectively ensuring the product's performance.

[0024] (7) The present invention can effectively overcome the problem of wear and deformation of counterweight balls and grooves in existing patents, greatly improve the service life of products, better ensure the shock absorption and noise reduction effect of products, and further promote the development and progress of enterprises and industries.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0034] Example 1

[0035] like Figure 1-3 As shown, an external fluid-type vibration damping and correction structure includes a vibration damping and correction structure disposed on a rotating structure that rotates around a rotation axis. The vibration damping and correction structure consists of at least two vibration damping and correction devices 100. The vibration damping and correction devices 100 are disposed on the same plane and are arranged around the rotation axis of the rotating structure. Each vibration damping and correction device 100 consists of a vibration damping and correction device body 101, a fluid tank 102 disposed in the vibration damping and correction device body 101, and a fluid counterweight 300 disposed in the fluid tank 102.

[0036] When setting up, the fluid tank is set perpendicular to the axis of rotation. When the rotating structure rotates, it will drive the vibration damping and correction device to rotate. When the vibration damping and correction device rotates, the fluid counterweight will be thrown towards the fluid tank away from the axis of rotation under the action of centrifugal force.

[0037] The fluid counterweight 300 is any one of water, oil, alcohol or metal fluid, and the weight of the fluid counterweight 300 in all the fluid tanks 102 in the vibration damping and correction device body 101 is the same; the volume of the fluid counterweight is less than 1 / 2 of the volume of the fluid tank 102.

[0038] The selection of fluid counterweights needs to be based on actual requirements. Firstly, a fluid substance that will not react with the materials it contacts must be selected. Secondly, substances of different densities need to be chosen according to the required correction force. The greater the required correction force, the higher the density of the fluid counterweight should be, and vice versa. The metallic fluid can be a single metal or a metal alloy, but it must remain liquid at the product's normal operating temperature. Specific material selection is prior art in this field, and those skilled in the art can select and use it without creative effort based on the above description; therefore, it will not be elaborated further here.

[0039] The portion of the fluid tank not filled with fluid counterweight needs to be filled with a specific gas according to the actual situation. It is necessary to ensure that the filling gas does not react with the material it is in contact with. If necessary, a vacuum operation can also be performed on it.

[0040] The vibration damping and correction device 100 consists of a vibration damping and correction device body 101, a fluid tank 102 disposed within the vibration damping and correction device body 101, and a sealing cover 200 that cooperates with the fluid tank 102.

[0041] The vibration damping and correction device body 101 is also provided with an installation groove 103 that communicates with the fluid tank 102, and the diameter of the installation groove 103 is larger than that of the fluid tank 102.

[0042] The upper section of the inner wall of the mounting groove 103 is provided with an internal thread. The bottom of the mounting groove 103 is provided with an inner sealing groove 105 for placing a sealing ring. An annular lower limit ring 107 is provided at the position where the inner sealing groove 105 contacts the fluid groove 102. The bottom of the mounting groove 103 is also provided with an outer sealing groove 104 whose inner side is connected to the inner sealing groove 105.

[0043] The bottom of the outer sealing groove 104 is arc-shaped, and an inwardly protruding convex ring 106 is also provided on the outer side wall of the outer sealing groove 104; the horizontal center line of the convex ring 106 and the center line of the sealing ring are located on the same plane.

[0044] The purpose of setting the convex ring is to make the middle part of the sealing ring bulge towards the sealing ring after the bottom end of the sealing ring is inserted into the outer sealing groove. Then, when it is subjected to the downward pressure of the spring, the convex part undergoes directional deformation, which promotes it to be tightly pressed onto the sealing ring, further ensuring that the sealing ring can be pressed inward, thereby improving the sealing effect of the sealing ring.

[0045] The sealing cover 200 consists of a sealing cover body 201, a sealing cover boss 202 that is located on the upper part of the outer side wall of the sealing cover body 201 and protrudes outward, a semi-circular groove 203 located on the lower side of the sealing cover body 201, a spring 204 that is sleeved on the outer side of the sealing cover body 201, a sealing ring 205 that is sleeved on the outer side of the sealing cover body 201 and contacts the spring 204, and an upper limit ring 206 located on the lower side of the sealing cover body 201 and cooperating with the lower limit ring 107.

[0046] The upper and lower limit rings work together to better limit the sealing ring and prevent it from falling into the fluid groove due to the pressure of the sealing ring.

[0047] During installation, as the sealing cap is tightened, the spring will gradually contract, thereby gradually increasing its elastic force. The increased elastic force of the spring will press down on the sealing ring. Under the action of the spring pressure, the sealing ring will deform inward at the position of the convex ring, and finally the deformed part of the sealing ring will press the sealing ring inward, effectively improving the sealing effect of the product and ensuring that the fluid counterweight will not leak out.

[0048] The bottom of the fluid groove 102 is semi-circular, and the diameter of the semi-circle is the same as the inner diameter of the fluid groove 102. The radius of the semi-circular groove 203 is the same as the inner diameter of the fluid groove 102. The outer wall of the sealing cover boss 202 is provided with an external thread that matches the internal thread on the mounting groove 103.

[0049] The sealing cap is screwed into the mounting groove by the engagement of internal and external threads.

[0050] When using the product, it needs to be installed on a rotating structure, ensuring that the axis of the fluid channel in the vibration damping and correction device body coincides with the rotation axis of the rotating structure. The specific installation method can be welding, embedding, or gluing, which can be determined according to actual installation requirements and will not be elaborated here.

[0051] The specific working principle is as follows: When the rotating structure rotates, the fluid counterweight is thrown to the end of the fluid tank away from the axis of rotation due to centrifugal force, and remains attached to the inner wall of the fluid tank end throughout the rotation. When the rotating structure vibrates at a high speed, it will undergo pre-displacement, which in turn causes the vibration damping and correction device body to also undergo pre-displacement. The side of the vibration damping and correction device body closer to the axis of rotation will collide with the fluid counterweight under the centrifugal force. When the collision force between the fluid counterweight and the vibration damping and correction device body is less than the force generated by the vibration, the displacement of the vibration damping and correction device body will be reduced, which will also reduce the displacement of the rotating structure, thus achieving the effect of reducing vibration. When the collision force between the fluid counterweight and the vibration damping and correction device body is equal to the force generated by the vibration, the vibration damping and correction device body will not displace, which will also prevent the rotating structure from displacing, thus achieving the effect of eliminating vibration.

[0052] Reducing or eliminating vibration in rotating structures can significantly reduce noise generated during their use, improve safety, stability, and rotational accuracy, and also reduce energy consumption required to maintain rotation, effectively promoting industry development.

[0053] Example 2

[0054] like Figure 4-7 As shown, the vibration damping and correction device 100 consists of an upper housing 108, a lower housing 110 that cooperates with the upper housing 108, four fixing holes 109 respectively disposed at the four corners of the upper housing 108 and the lower housing 110 and cooperating with each other, an upper fluid groove 111 disposed on the lower side of the upper housing 108, a lower fluid groove 112 disposed on the upper side of the lower housing 110 and cooperating with the upper fluid groove 111, and sealing structures respectively disposed on the upper housing 108 and the lower housing 110 and cooperating with each other; the upper housing 108 and the lower housing 110 cooperate to form the vibration damping and correction device body 101; the upper fluid groove 111 and the lower fluid groove 112 cooperate to form the fluid groove 102.

[0055] The upper and lower boxes can be effectively fixed by using bolts that pass through the fixing holes of both the upper and lower boxes. This fixing method is existing technology, and those skilled in the art can fix the upper and lower boxes without creative effort based on the above description, so it will not be elaborated here.

[0056] The sealing structure consists of a lower sealing groove 113 surrounding the lower fluid groove 112 and disposed on the lower housing 110, an upper sealing groove 116 surrounding the upper fluid groove 111 and disposed on the upper housing 108, an annular sealing ring 115 disposed between the lower sealing groove 113 and the upper sealing groove 116, a deformable socket 114 disposed on the outer edge of the lower sealing groove 113, and a deformable plug 117 disposed on the outer edge of the upper sealing groove 116 and cooperating with the deformable socket 114.

[0057] When selecting an annular sealing ring, it is necessary to choose a model whose diameter matches the lower sealing groove. After the upper and lower housings are fastened together, the deformable plug will be inserted into the deformable socket. The deformable plug will then occupy the space on the outer edge of the lower sealing groove, causing it to contact the outer side of the annular sealing ring and exert inward pressure on it. Under the pressure of the deformable plug, the annular sealing ring will deform inward. After deformation, the annular sealing ring will effectively fill the inner contact area of ​​the upper and lower sealing grooves, thus better filling the gaps and further ensuring the sealing effect of the product. This prevents fluid counterweight from overflowing, which could reduce product performance or even cause failure, effectively ensuring the product's performance.

[0058] Its usage and specific principles are the same as those in Example 1, and will not be repeated here.

[0059] As described above, the present invention can be well implemented.
