Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vacuum pump technology, specifically relating to a vibration damping bracket and a vacuum pump. Background Technology
[0002] The combined Roots vacuum pump includes an upper pump body and a lower pump body, which are connected by a connecting bracket. The connecting bracket enables the connection between the upper and lower pump bodies and can stably support the upper pump body and bear its load.
[0003] In related technologies, the connecting bracket between the upper and lower pump bodies lacks vibration damping functionality. During operation, the upper and lower pump bodies experience significant vibration and noise due to wear and damage to transmission components, impeller imbalance, and other issues. The connecting bracket transmits the vibration of the upper pump body to the lower pump body, thus exacerbating the vibration of the lower pump body and severely affecting the normal operation of the combined Roots vacuum pump. Furthermore, the increased vibration of the lower pump body generates significant noise, causing noise pollution to the surrounding environment. Utility Model Content

[0044] like Figures 1 to 3 As shown, an embodiment of this disclosure provides a vibration damping bracket 100 for connecting the upper pump body (not shown) and lower pump body (not shown) of a vacuum pump (not shown in the figure). The vibration damping bracket 100 includes a bracket assembly 10 and a vibration damping assembly 20. The bracket assembly 10 includes a bracket body 11, which includes a first support member 111 and a second support member 112. The first support member 111 is connected to the second support member 112, and the extending direction of the first support member 111 intersects the extending direction of the second support member 112. The vibration damping assembly 20 is connected to the first support member 111 and is used to connect the upper pump body of the vacuum pump. The second support member 112 is used to connect the lower pump body of the vacuum pump. And / or, the vibration damping assembly 20 is connected to the second support member 112 and is used to connect the lower pump body of the vacuum pump. The first support member 111 is used to connect the upper pump body of the vacuum pump.
[0045] The vibration damping bracket 100 of this embodiment includes a bracket assembly 10 and a vibration damping assembly 20. The bracket assembly 10 includes a bracket body 11, each bracket body 11 including a first support member 111 and a second support member 112. The first support member 111 is connected to the second support member 112, and the second support member 112 extends from the first support member 111 in a direction away from other bracket bodies 11. When the first support member 111 is connected to one end of the vibration damping assembly 20, the other end of the vibration damping assembly 20 is used to connect to the upper pump body. The end of the second support member 112 facing away from the first support member 111 is connected to the lower pump body. By placing the vibration damping assembly 20 on the first support member 111, the vibration damping assembly 20 connects the upper pump body to the first support member 111 of the bracket body 11. The vibration damping assembly 20 buffers the vibration of the upper pump body, thereby reducing the vibration transmitted from the upper pump body to the bracket body 11, and further reducing the vibration transmitted from the upper pump body to the lower pump body through the bracket body 11. When the second support member 112 is connected to one end of the vibration damping component 20, the other end of the vibration damping component 20 is used to connect to the lower pump body, and the end of the first support member 111 facing away from the second support member 112 is connected to the upper pump body. By placing the vibration damping component 20 on the second support member 112, the vibration damping component 20 connects the lower pump body to the second support member 112 of the support body 11. The vibration damping component 20 buffers the vibration transmitted from the upper pump body to the support body 11, thereby reducing the vibration transmitted from the support body 11 to the lower pump body, and further reducing the vibration transmitted from the upper pump body to the lower pump body through the support body 11. When the second support member 112 is connected to the lower pump body by one vibration damping component 20, the end of the first support member 111 facing away from the second support member 112 is connected to the upper pump body through another vibration damping component 20. That is, a vibration damping component 20 is provided at each end of the support body 11, and the two ends of the support body 11 are connected to the upper pump body and the lower pump body respectively through the vibration damping component 20. The vibration damping components 20 at both ends of the support body 11 are connected to the upper and lower pump bodies respectively, providing a dual vibration damping effect. The vibration damping components 20 reduce the vibration transmitted from the support body 11 to the upper and lower pump bodies, reducing the superposition of vibrations between the upper and lower pump bodies, ensuring the normal operation of the vacuum pump. Simultaneously, they reduce the significant noise generated by the superposition of vibrations between the upper and lower pump bodies, minimizing noise pollution to the surrounding environment.
[0046] In some embodiments of this disclosure, the support assembly 10 includes two support bodies 11, which are disposed opposite to the two sides of the vacuum pump. The two support bodies 11 are connected to the upper pump body and the lower pump body from the two sides of the vacuum pump, respectively, and reduce or block the vibration transmission between the upper pump body and the lower pump body from the two sides of the vacuum pump, so that the vibration reduction on both sides of the vacuum pump is relatively balanced and the force is relatively balanced.
[0047] In some embodiments of this disclosure, when the vibration damping components 20 are connected to the first support member 111, the first support member 111 of each bracket body 11 is connected to two vibration damping components 20. The two vibration damping components 20 are spaced apart along the extending direction of the first support member 111 on the side of the first support member 111 facing away from the second support member 112. Connecting the bracket body 11 to the upper pump body via the two vibration damping components 20 improves the vibration damping effect of the vibration damping bracket 100. By spaced the two vibration damping components 20 along the extending direction of the first support member 111, one side of the upper pump body is connected to the bracket body 11 via the two vibration damping components 20, thereby making the force on the upper pump body of the vacuum pump more uniform, reducing force concentration on the upper pump body, and improving the service life of the upper pump body.
[0048] In some embodiments of this disclosure, each support body 11 includes two second support members 112, which are spaced apart and connected to the side of the first support member 111 facing away from the upper pump body along the extending direction of the first support member 111. By connecting the two second support members 112 to the first support member 111, the force exerted by the upper pump body on the first support member 111 by the two second support members 112 is dispersed, thereby making the force on the lower pump body, which is directly or indirectly connected to the second support members 112, more uniform, reducing force concentration on the lower pump body, and improving the service life of the lower pump body. When the vibration damping component 20 is connected to the second support member 112, a vibration damping component 20 is provided at the end of each second support member 112 facing away from the first support member 111.
[0049] In some embodiments of this disclosure, when the vibration damping component 20 is connected to the first support member 111, the first support member 111 includes two support portions 1111 and a connecting portion 1112. The two support portions 1111 are disposed at both ends in the extending direction of the connecting portion 1112. At least one support portion 1111 is connected to the vibration damping component 20. Specifically, the two support portions 1111 are respectively connected to the two vibration damping components 20 to realize the connection between the two vibration damping components 20 and the support body 11.
[0050] Furthermore, the thickness of the support portion 1111 is greater than the thickness of the connecting portion 1112 to ensure the supporting capacity of the support portion 1111 and improve its service life. Specifically, in this embodiment, the first support member 111 is a plate structure, that is, both the support portion 1111 and the connecting portion 1112 are plate structures, and the two thicker support portions 1111 are respectively arranged at both ends of the connecting portion 1112. In this embodiment, the first support member 111 is an integrally formed structure, that is, the support portion 1111 and the connecting portion 1112 are integrally formed structures.
[0051] like Figures 4 to 7As shown, the vibration damping assembly 20 includes: a first mounting base 21, a second mounting base 22, a damping element 23, and an elastic element 24. The first mounting base 21 has an open mounting space, and the second mounting base 22 has an open mounting space. The openings of the first mounting base 21 and the second mounting base 22 are opposite to each other, allowing the damping element 23 and the elastic element 24 to be installed between the first mounting base 21 and the second mounting base 22. Specifically, when the vibration damping assembly 20 is located on the first support member 111, the first mounting base 21 is used to connect to the upper pump body, and the second mounting base 22 is connected to the first support member 111; when the vibration damping assembly 20 is located on the second support member 112, the first mounting base 21 is used to connect to the lower pump body, and the second mounting base 22 is connected to the second support member 112.
[0052] Furthermore, the two ends of the damping member 23 are respectively connected to the first mounting base 21 and the second mounting base 22. Specifically, one end of the damping member 23 enters the mounting space of the first mounting base 21 through the opening and is connected to the bottom of the first mounting base 21, and the other end of the damping member 23 enters the mounting space of the second mounting base 22 through the opening and is connected to the bottom of the second mounting base 22. The two ends of the elastic member 24 are respectively connected to the first mounting base 21 and the second mounting base 22. Specifically, one end of the elastic member 24 enters the mounting space of the first mounting base 21 through the opening and is connected to the bottom of the first mounting base 21, and the other end of the elastic member 24 enters the mounting space of the second mounting base 22 through the opening and is connected to the bottom of the second mounting base 22. The elastic element 24 is arranged along the circumference of the damping element 23. Through the cooperation of the elastic element 24 and the damping element 23, the energy caused by vibration reduction can be dissipated, thereby enabling the vibration reduction assembly 20 to achieve the purpose of vibration reduction.
[0053] Specifically, the elastic element 24 is a spring. When the diameter of the spring is greater than the diameter of the damping element 23, the number of springs can be one, with one spring sleeved on the damping element 23. When the diameter of the spring is less than or equal to the diameter of the damping element 23, the number of springs can be two or more, with two or more springs spaced apart and evenly arranged along the circumference of the damping element 23.
[0054] In this embodiment, the damping element 23 can be any one of a liquid damper, a viscous damper, an electromagnetic damper, or a tuned mass damper.
[0055] like Figure 4 , Figure 5As shown, the vibration damping assembly 20 also includes a connector 25, which includes a bolt 251 and a nut 252. The bolt 251 passes through the first mounting base 21, and the nut 2511 of the bolt 251 is located within the mounting space of the first mounting base 21. The thread 2512 of the bolt 251 extends to the outside of the first mounting base 21 in a direction away from the second mounting base 22. When the vibration damping assembly 20 is connected to the upper pump body, the bolt 251 is threadedly connected to the upper pump body; when the vibration damping assembly 20 is connected to the lower pump body, the bolt 251 is threadedly connected to the lower pump body. The nut 252 is located on the side of the first mounting base 21 away from the opening of the mounting space. Through the threaded engagement between the nut 252 and the thread 2512, the nut 252 is tightly engaged with the first mounting base 21, thereby ensuring a tight connection between the connector 25 and the first mounting base 21.
[0056] Furthermore, the connector 25 also includes a fixing plate 253, which is located on the side of the first mounting base 21 opposite to the second mounting base 22, i.e., the fixing plate 253 is located on the side of the first mounting base 21 opposite to its opening, and the fastener is located between the nut 252 and the first mounting base 21, with the bolt 251 passing through the fixing plate 253. By setting the fixing plate 253 between the nut 252 and the first mounting base 21, the tightness of the connection between the first mounting base 21 and the nut 252 can be improved. At the same time, since the bottom thickness of the first mounting base 21 is limited, the setting of the fixing plate 253 is equivalent to thickening the bottom thickness of the first mounting base 21, thereby extending the service life of the first mounting base 21.
[0057] In some embodiments of this disclosure, the connector 25 further includes a protective cover 254. The protective cover 254 is connected to the side of the fixing plate 253 near the first mounting base 21 and extends towards the second mounting base 22. The protective cover 254 is arranged circumferentially along the first mounting base 21 to prevent other objects from affecting the normal operation of the damping member 23 and the elastic member 24. The diameter of the protective cover 254 is slightly larger than the overall diameter of the vibration damping structure formed by the elastic member 24 and the damping member 23. That is, the protective cover 254 serves as a guide for the vibration damping structure formed by the elastic member 24 and the damping member 23 to prevent the movement trajectory of the vibration damping assembly 20 from deviating and to improve the reliability of the vibration damping assembly 20. In this embodiment, the protective cover 254 does not affect the normal operation of the damping member 23 and the elastic member 24.
[0058] In some embodiments of this disclosure, when the vibration damping component 20 is disposed on the first support member 111, a vibration damping mounting base 26 is embedded on the side of the first support member 111 opposite to the second support member 112, and one end of the vibration damping component 20 is connected to the vibration damping mounting base 26. When the vibration damping component 20 is disposed on the second support member 112, a vibration damping mounting base 26 is embedded on the side of the second support member 112 opposite to the first support member 111, and one end of the vibration damping component 20 is connected to the mounting space of the vibration damping mounting base 26. The provision of the vibration damping mounting base 26 improves the reliability of the connection between the vibration damping component 20 and the bracket body 11.
[0059] The second aspect of this disclosure provides a vacuum pump (not shown in the figure), the vacuum pump including an upper pump body, a lower pump body and a vibration damping bracket 100, the vibration damping bracket 100 connecting the upper pump body and the lower pump body, the vibration damping bracket 100 being the vibration damping bracket 100 according to any of the above embodiments.
[0060] The vacuum pump in this embodiment includes an upper pump body, a lower pump body, and a vibration damping bracket 100. The vibration damping bracket 100 connects the upper pump body and the lower pump body. The vibration damping bracket 100 includes a bracket assembly 10 and a vibration damping component 20. The bracket assembly 10 includes a bracket body 11. Each bracket body 11 includes a first support member 111 and a second support member 112. The first support member 111 is connected to the second support member 112, and the extension direction of the first support member 111 intersects the extension direction of the second support member 112. When the first support member 111 is connected to one end of the vibration damping component 20, the other end of the vibration damping component 20 is used to connect to the upper pump body. The end of the second support member 112 facing away from the first support member 111 is connected to the lower pump body. By placing the vibration damping component 20 on the first support member 111, the vibration damping component 20 connects the upper pump body to the first support member 111 of the bracket body 11. The vibration damping component 20 buffers the vibration of the upper pump body, thereby reducing the vibration transmitted from the upper pump body to the bracket body 11, and further reducing the vibration transmitted from the upper pump body to the lower pump body through the bracket body 11. When the second support member 112 is connected to one end of the vibration damping component 20, the other end of the vibration damping component 20 is used to connect to the lower pump body, and the end of the first support member 111 facing away from the second support member 112 is connected to the upper pump body. By placing the vibration damping component 20 on the second support member 112, the vibration damping component 20 connects the lower pump body to the second support member 112 of the bracket body 11. The vibration damping component 20 buffers the vibration transmitted from the upper pump body to the bracket body 11, thereby reducing the vibration transmitted from the bracket body 11 to the lower pump body, and further reducing the vibration transmitted from the upper pump body to the lower pump body through the bracket body 11. By reducing the vibration transmitted from the upper pump body to the lower pump body through the support body 11, the superposition of the vibrations of the upper and lower pump bodies is reduced, ensuring the normal operation of the vacuum pump. At the same time, the large noise generated by the superposition of the vibrations of the upper and lower pump bodies is reduced, thus reducing noise pollution to the surrounding environment.
[0061] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
