Description

Technical Field

[0001] This application relates to the field of gear transmission system technology, and in particular to a vibration reduction and noise reduction device for a flexible connection gear transmission system. Background Technology

[0002] A gear transmission system is a mechanical device that transmits power and converts motion through meshing gear pairs. Its core consists of a driving gear, a driven gear, and a support structure. It transmits torque and changes speed through tooth meshing (e.g., a small gear drives a large gear to achieve speed reduction and torque increase). It has advantages such as precise transmission ratio, high efficiency (up to 98% to 99%), and strong load-bearing capacity. It is widely used in automotive gearboxes (achieving multi-gear speed regulation through multi-stage gear sets), industrial machine tools (achieving high-precision indexing through indexing head gear sets), and watches (achieving energy transmission and timekeeping through micro gear sets). However, attention should be paid to the noise and vibration generated by gear meshing. This is usually improved by optimizing the tooth profile (e.g., using helical gears instead of spur gears), improving machining accuracy, and adding lubricants. At the same time, regular maintenance is required to prevent transmission failure caused by wear.

[0003] Publication number (CN214425032U) discloses a gear transmission system comprising: a housing, a rotating shaft disposed on the housing, a first gear coaxially disposed on the rotating shaft, a second gear coaxially disposed on the rotating shaft and rotatable relative to the rotating shaft, a rod disposed on the housing, a third gear coaxially disposed on the rod and slidable along the rod, and a positioning mechanism for positioning the third gear at a first position or a second position on the rod; when the gear is in the first position, the third gear meshes with both the first and second gears; when the gear is in the second position, the third gear disengages from the second gear. When the first gear slides to the first position, the third gear meshes with both the first and second gears, and the first gear drives the second gear to rotate through the third gear; when the first gear slides to the second position, the third gear disengages from the second gear.

[0004] In practical use, the aforementioned patent does not have the function of damping the gear transmission system. Since the gear transmission system generates significant vibration during operation, failure to dampen the vibration will damage the gear transmission system, affect its service life, and make it unsuitable for use by operators. Therefore, we propose a vibration damping and noise reduction device for a flexible connection gear transmission system. Utility Model Content

[0005] This application provides a vibration reduction and noise reduction device for a flexible connection gear transmission system to solve the vibration problem of the gear transmission system.

[0006] This application provides a vibration reduction and noise reduction device for a flexible connection gear transmission system, including a housing, a mounting plate on the top of the housing, a gear transmission system body fixedly mounted on the top of the mounting plate, six second damping pads fixedly connected to both sides of the inner wall of the housing, a slide rod fixedly connected between every two second damping pads, a first vibration damping component disposed on the outside of each of the three slide rods, and a first vibration damping component disposed inside the housing.

[0007] Preferably, the first vibration damping component includes a first slider, which is slidably mounted on the outside of a slide rod, and a second slider is slidably mounted on the outside of the slide rod. A first rotating frame is fixedly connected to the top of the first slider and the bottom of the mounting plate, and a second rotating frame is fixedly connected to the top of the second slider and the bottom of the mounting plate.

[0008] Preferably, the two first rotating frames are fixedly connected by the same first connecting rod, and the two second rotating frames are fixedly connected by the same second connecting rod.

[0009] Preferably, a second spring is provided on one side of both the first slider and the second slider, and the other end of the second spring is fixedly connected to the corresponding second damping pad.

[0010] Preferably, the second vibration damping component includes three first damping pads, each of the tops of which is fixedly connected to a telescopic sleeve, and each of the three telescopic sleeves has a telescopic rod slidably installed inside, with the tops of the three telescopic rods fixedly connected to the bottom of the mounting plate.

[0011] Preferably, a first spring is provided on the top of each of the three first damping pads, and the other end of each of the three first springs is fixedly connected to the bottom of the mounting plate.

[0012] Preferably, a soundproof cover is fixedly connected to the top of the mounting plate, and the main body of the gear transmission system is located inside the soundproof cover.

[0013] Beneficial effects:

[0014] Considering the vibration issue during the operation of the gear transmission system, a soundproof cover is installed to block the noise generated by the main body of the gear transmission system during operation. When the main body of the gear transmission system vibrates during operation, the mounting plate moves downward, causing the telescopic rod to slide inside the telescopic sleeve. The first spring is compressed, generating compressive force, which is transmitted to the first damping pad. The first damping pad absorbs the compressive force, thereby reducing the vibration of the main body of the gear transmission system. When the mounting plate moves, it causes the first and second rotating frames to move downward. This is achieved by installing two first rotating frames and two second rotating frames... The first and second connecting rods, through the movement of the first rotating frame, drive the first and second sliders to move simultaneously. The first and second sliders will respectively compress the second spring, and the second spring will generate compressive force. The compressive force will be transmitted to the second damping pad, which will absorb the compressive force, thereby further reducing the vibration of the gear transmission system. Through the above structure, the noise generated when the gear transmission system is working can be blocked, and the vibration of the gear transmission system can be reduced, avoiding the phenomenon that vibration will damage the gear transmission system, thus facilitating the use of the operator.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-4 The device shown is a vibration reduction and noise reduction device for a flexible gear transmission system. It includes a housing 1, a mounting plate 2 on the top of the housing 1, a gear transmission system body 4 fixedly mounted on the top of the mounting plate 2, six second damping pads 10 fixedly connected to both sides of the inner wall of the housing 1, a slide rod 9 fixedly connected between every two second damping pads 10, a first vibration damping component on the outside of each of the three slide rods 9, and a first vibration damping component inside the housing 1.

[0030] The soundproof cover 3 effectively blocks the noise generated by the gear transmission system body 4 during operation. When the gear transmission system body 4 vibrates during operation, the mounting plate 2 moves downward, causing the telescopic rod 7 to slide inside the telescopic sleeve 6. The first spring 8 is compressed, generating a compressive force that is transmitted to the first damping pad 5. The first damping pad 5 absorbs the compressive force, thereby reducing the vibration of the gear transmission system body 4. When the mounting plate 2 moves, it causes the first rotating frame 12 and the second rotating frame 14 to move downward. The first connecting rod 15, which is located between the two first rotating frames 12 and the two second rotating frames 14, connects to the second connecting rod 14. Rod 17, through the movement of the first rotating frame 12, drives the first slider 11 and the second slider 13 to move simultaneously. The first slider 11 and the second slider 13 will respectively squeeze the second spring 16, and the second spring 16 will generate a squeezing force, which will be transmitted to the second damping pad 10. At this time, the second damping pad 10 can absorb the squeezing force, thereby further reducing the vibration of the gear transmission system body 4. Through the above structure, the noise generated when the gear transmission system body 4 is working can be blocked, and the vibration of the gear transmission system body 4 can be reduced, avoiding the phenomenon that vibration will damage the gear transmission system body 4, thus facilitating the use of the staff.

[0031] The first vibration damping component includes a first slider 11, which is slidably mounted on the outside of the slide rod 9. A second slider 13 is slidably mounted on the outside of the slide rod 9. A first rotating frame 12 is fixedly connected to the top of the first slider 11 and the bottom of the mounting plate 2. A second rotating frame 14 is fixedly connected to the top of the second slider 13 and the bottom of the mounting plate 2.

[0032] In this process, the first slider 11 and the second slider 13 move simultaneously, and the first slider 11 and the second slider 13 will respectively squeeze the second spring 16, and the second spring 16 will generate a squeezing force.

[0033] The two first rotating frames 12 are fixedly connected by the same first connecting rod 15, and the two second rotating frames 14 are fixedly connected by the same second connecting rod 17.

[0034] Specifically, by setting a first connecting rod 15 and a second connecting rod 17 between the two first rotating frames 12 and the two second rotating frames 14, the movement of the first rotating frame 12 can drive the first slider 11 and the second slider 13 to move simultaneously.

[0035] A second spring 16 is provided on one side of both the first slider 11 and the second slider 13, and the other end of the second spring 16 is fixedly connected to the corresponding second damping pad 10.

[0036] The compressive force is transmitted to the second damping pad 10, which absorbs the compressive force and further reduces the vibration of the gear transmission system body 4.

[0037] The second vibration damping assembly includes three first damping pads 5, each of which is fixedly connected to a telescopic sleeve 6 at its top. Each of the three telescopic sleeves 6 has a telescopic rod 7 slidably installed inside it, and the top of each of the three telescopic rods 7 is fixedly connected to the bottom of the mounting plate 2.

[0038] The compressive force is transmitted to the first damping pad 5, which absorbs the compressive force and thus reduces the vibration of the main body 4 of the gear transmission system. The telescopic rod 7 is slidably installed inside the telescopic sleeve 6, which makes the mounting plate 2 more stable when it moves.

[0039] Each of the three first damping pads 5 is provided with a first spring 8 at its top, and the other end of each of the three first springs 8 is fixedly connected to the bottom of the mounting plate 2.

[0040] In this process, the first spring 8 will be compressed, generating compressive force. This compressive force will be transmitted to the first damping pad 5, which will absorb the compressive force, thereby reducing the vibration of the gear transmission system body 4.

[0041] The top of the mounting plate 2 is fixedly connected to the soundproof cover 3, and the main body 4 of the gear transmission system is set inside the soundproof cover 3.

[0042] The noise generated by the gear transmission system body 4 during operation can be blocked by the soundproof cover 3.

[0043] Working Principle: This vibration reduction and noise reduction device for a flexible gear transmission system uses a soundproof cover 3 to block noise generated by the main body 4 of the gear transmission system during operation. When the main body 4 of the gear transmission system vibrates during operation, the mounting plate 2 moves downwards, causing the telescopic rod 7 to slide inside the telescopic sleeve 6. The first spring 8 is compressed, generating a compressive force that is transmitted to the first damping pad 5. The first damping pad 5 absorbs the compressive force, thereby reducing the vibration of the main body 4 of the gear transmission system. As the mounting plate 2 moves, it causes the first rotating frame 12 and the second rotating frame 14 to move downwards. This is achieved by using the two first rotating frames 12 and the two second rotating frames 14... The first connecting rod 15 and the second connecting rod 17 between the gear transmission system 4 can drive the first slider 11 and the second slider 13 to move simultaneously through the movement of the first rotating frame 12. The first slider 11 and the second slider 13 will respectively squeeze the second spring 16, and the second spring 16 will generate a squeezing force. The squeezing force will be transmitted to the second damping pad 10. At this time, the second damping pad 10 can absorb the squeezing force, thereby further reducing the vibration of the gear transmission system body 4. With the above structure, the noise generated when the gear transmission system body 4 is working can be blocked, and the vibration of the gear transmission system body 4 can be reduced, avoiding the phenomenon that vibration will damage the gear transmission system body 4, thus facilitating the use of the staff.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
