Description

Technical Field

[0001] This invention relates to the field of gear transmission technology, and in particular to a noise-reducing and shock-resistant gear structure and transmission device. Background Technology

[0002] Gears play a core role in mechanical power transmission systems, ensuring the normal operation of various devices (such as automotive transmissions) and optimizing power distribution through precise adjustments of speed and direction. Specifically, in automotive applications, gears change the direction of power transmission to meet rear-wheel drive requirements and accelerate or decelerate machines through the meshing of gears of different sizes, thus becoming an indispensable key component in mechanical power transmission. However, gears inevitably vibrate during operation, and their vibration frequencies can easily cause resonance, leading to significant noise problems. Simultaneously, the meshing collisions between gears generate impact forces; when these impact forces exceed a critical threshold, they can cause gear structure failure, leading to equipment malfunctions and severely impacting reliability and system stability. Summary of the Invention

[0007] Optionally, the lubrication assembly further includes an arc-shaped plate connected to the end face of the pressing column away from the second spring, a support block slidably mounted on the outer wall of the arc-shaped plate, an oil inlet disposed on the outer wall of the oil pipe, and a linkage assembly for blocking the oil inlet located on the front side of the gear body.

[0008] Optionally, the linkage assembly includes a hinge block fixedly installed on the top of the gear body, an opening and closing spring fixedly installed in the groove of the hinge block, a moving block fixedly connected to the end of the opening and closing spring away from the hinge block and slidably connected to the hinge block, a hinge rod attached to the bottom of the moving block, and an oil inlet cap fixedly connected to the outer wall of the hinge rod; when the linkage assembly blocks the oil inlet, the oil inlet cap covers the oil inlet to block it.

[0009] Optionally, multiple lubrication components are provided, and the multiple lubrication components are distributed in a circumferential array about the center of the rotating shaft sleeve.

[0010] Optionally, the noise-reducing and shock-resistant gear structure further includes an idler assembly, which includes an annular groove formed on the outer wall of the rotating shaft sleeve, a ring slidably installed in the annular groove, a return spring with its bottom connected between the inner side wall of the annular groove and the ring, and a positioning bolt fixedly connected to the end face of the ring away from the return spring.

[0011] Optionally, the idling assembly further includes a guide member, which includes a connecting rod hinged to the outer wall of the ring, and a round rod hinged to the end face of the connecting rod away from the connecting rod; the outer wall of the round rod penetrates the inner wall of the gear body and is slidably connected to the gear body; the round rod is used to drive the connecting rod to pull the ring to slide in the annular groove.

[0012] Optionally, the idling assembly further includes a locking element, which includes a groove formed on the front side of the gear teeth of the gear body, a slider slidably mounted in the groove, and a pop-out spring abutting against the inner wall of the groove and the groove; the end of the round rod away from the connecting rod is slidably connected to the slider.

[0013] Optionally, multiple round rods are provided, and the multiple round rods are distributed in a circumferential array about the center of the rotating sleeve; and each round rod is connected to one of the locking elements.

[0014] The present invention also provides a transmission device, including the above-described noise-reducing and shock-resistant gear structure.

[0015] The present invention has the following beneficial effects:

[0016] Firstly, this invention effectively solves the problems of high noise and easy damage caused by impact and vibration during the operation of traditional gears through cleverly designed buffer and noise reduction components. Specifically, when the gear starts working and generates noise, the sound-absorbing cotton can absorb part of the sound waves, significantly reducing noise propagation. When the gear is subjected to a large impact force, the gear body drives the fixed frame to squeeze the telescopic rod, causing the gear body to move eccentrically, thereby dispersing the impact force and preventing it from being concentrated on the gear body. When the impact force disappears, the moving spring and sliding spring release energy, pushing the gear body back to its initial state. This process not only achieves noise reduction and impact protection but also effectively protects the gear body and extends its service life.

[0017] Secondly, the lubrication component design of this invention further enhances the service life and operational stability of the gears. When gear lubrication is insufficient, lubricating oil is added to the hollow groove of the gear body by opening the oil inlet cap. When the telescopic rod is compressed, the pressing column presses the oil pipe, drawing lubricating oil from the oil outlet into the space between the arc-shaped plate and the support block. Subsequently, the resetting of the telescopic rod causes the arc-shaped plate to reset, pushing the lubricating oil out of the lubrication port and evenly coating the gear teeth. This automatic lubrication mechanism not only ensures that the gears maintain good lubrication during operation but also reduces wear caused by insufficient lubrication, further improving the gear's operating efficiency and reliability.

[0018] Finally, the idling component design of this invention provides crucial safety for the gears. After prolonged operation, the gear teeth may break. If a tooth breaks, the locking element at the top of the slide groove will open, releasing a spring that pushes the slider out of the slide groove. The slider's movement causes the round rod to slide, which in turn moves the ring upwards in the annular groove, causing the positioning pin to disengage from the notch in the rotating ring. At this point, the rotating sleeve can idle, and the rotating ring slides on the outer wall of the rotating sleeve, thus preventing the gear from continuing to operate after damage and avoiding further damage to the machine. This design significantly improves the safety and reliability of the gear transmission system, reducing equipment maintenance costs and downtime.

[0019] In summary, the noise-reducing and impact-resistant gear structure of the present invention, through the synergistic effect of the buffer component, lubrication component, and idling component, not only effectively reduces noise and impact force, but also significantly improves the service life and operational stability of the gear, while providing a strong guarantee for the safe operation of the transmission device.

[0032] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0033] In the description of this invention, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] like Figures 1 to 9 As shown, an embodiment of the present invention provides a noise-reducing and shock-resistant gear structure, including a gear body 1, a buffer assembly 2 disposed inside the gear body 1, and a noise-reducing assembly 5; an arc-shaped plate 312 is connected to the inner wall of the hollow groove of the gear body 1; the buffer assembly 2 includes a rotating bushing 21 disposed inside the gear body 1, a sliding groove 23 formed on the rotating bushing 21, a plurality of evenly spaced rotating rings 22 slidably mounted in the sliding groove 23 and rotatably connected to the outer wall of the rotating bushing 21, sliding blocks 25 connecting adjacent rotating rings 22, and adjacent sliding blocks 25. The system includes a sliding spring 24 disposed between the rotating ring 22, a telescopic rod 26 fixedly connected to the end face of the sliding block 25 away from the sliding groove 23, a movable spring 27 fixedly installed in the inner cavity of the telescopic rod 26, and multiple fixing brackets 28 connecting the end face of the telescopic rod 26 away from the sliding block 25; the end face of the fixing brackets 28 away from the telescopic rod 26 is connected to the arc-shaped plate 312; the noise reduction component 5 includes sound-absorbing cotton 51, which is fixedly installed in multiple mounting slots (not shown) formed by the multiple fixing brackets 28 separating the hollow slots of the gear body 1. Understandably, through the cleverly designed buffer component 2 and noise reduction component 5, the problems of high noise and easy damage caused by impact and vibration during gear operation are effectively solved. This addresses the pain points of traditional gears caused by high noise and easy damage due to impact and vibration. Specifically, in the buffer assembly 2, the rotating bushing 21 provides rotational support for the rotating ring 22, and the sliding groove 23 defines the movement trajectory of the sliding block 25. The sliding block 25 forms a multi-stage elastic buffer unit through the sliding spring 24 and the moving spring 27 in the telescopic rod 26. When the gear is impacted, the impact force is transmitted to the telescopic rod 26 through the fixed frame 28, driving the sliding block 25 to slide in the sliding groove 23, compressing / stretching the sliding spring 24 and the moving spring 27, converting the concentrated impact force into spring potential energy and dissipating it, thus preventing the gear body 1 from breaking due to excessive local stress, and significantly improving its impact resistance and service life. At the same time, in the noise reduction assembly 5, the sound-absorbing cotton 51 is embedded in the independent mounting groove formed by the fixed frame 28, directly wrapping the gear vibration source, and converting the mid-to-high frequency noise generated by meshing into heat energy absorption through the porous structure, thus absorbing the noise transmission.

[0036] In one embodiment, such as Figures 1 to 7 As shown, the noise-reducing and shock-resistant gear structure also includes a lubrication assembly 3. The lubrication assembly 3 includes a movable rod 31 slidably mounted in the through hole of the fixed frame 28, an oil pipe 32 passing through the movable rod 31, an oil outlet 33 on the outer wall of the oil pipe 32, a hemisphere 34 fitted in the groove of the movable rod 31, a first spring 35 connecting the hemisphere 34, a pull plate 36 fixedly connected to the end of the first spring 35 away from the hemisphere 34, a pressing column 38 slidably mounted in the groove of the movable rod 31, a second spring 37 connecting the pull plate 36 and the pressing column 38, a first baffle plate 39 fixedly connected to the inner wall of the through hole of the pressing column 38, a spherical block 310 fitted to the left side of the first baffle plate 39, a second baffle plate 311 fixedly mounted in the through hole of the movable rod 31, and a lubrication port 320 on the outer wall of the gear body 1; the bottom of the movable rod 31 is fixedly mounted on the front of the telescopic rod 26.

[0037] Understandably, when the gear body 1 is impacted, the telescopic rod 26 presses the moving rod 31, pushing the pressing column 38 to compress the second spring 37. The volume of the groove in the moving rod 31 decreases and the pressure increases, causing the spherical block 310 to move to the left to expel air. After the pressure balances, the spherical block 310 resets and closes. After the impact subsides, the second spring 37 pushes the pressing column 38 to reset, increasing the volume of the groove in the moving rod 31 and creating a negative pressure. This attracts the semi-spherical ball 34 to open, and lubricating oil is drawn into the groove from the oil outlet 33. Subsequently, the telescopic rod 26 resets, causing the moving rod 31 to reset, squeezing the lubricating oil in the groove and spraying it out from the lubrication port 320, evenly covering the gear surface. This process requires no external energy and achieves a closed loop of "oil suction-oil storage-oil spraying" through the synergistic effect of the impact force and the spring, effectively reducing gear surface wear and extending the service life of the gear.

[0038] In one embodiment, such as Figure 3 , Figures 5 to 6 As shown, the lubrication assembly 3 further includes an arc-shaped plate 312 connected to the end face of the pressing column 38 away from the second spring 37, a support block 313 slidably mounted on the outer wall of the arc-shaped plate 312, an oil inlet 314 disposed on the outer wall of the oil pipe 32, and a linkage assembly for blocking the oil inlet 314 located on the front side of the gear body 1. Understandably, the support block 313 is slidably mounted on the outer wall of the arc-shaped plate 312. This design can more effectively control the flow direction and flow rate of the lubricating oil, ensuring that the lubricating oil is evenly distributed on the surface of the gear body 1. The oil inlet 314 is disposed on the outer wall of the oil pipe 32, providing a convenient channel for replenishing the lubricating oil.

[0039] In one embodiment, such as Figure 7As shown, the linkage assembly includes a hinge block 315 fixedly mounted on the top of the gear body 1, an opening and closing spring 316 fixedly mounted in the groove of the hinge block 315, a moving block 317 fixedly connected to one end of the opening and closing spring 316 away from the hinge block 315 and slidably connected to the hinge block 315, a hinge rod 318 attached to the bottom of the moving block 317, and an oil inlet cap 319 fixedly connected to the outer wall of the hinge rod 318; when the linkage assembly blocks the oil inlet 314, the oil inlet cap 319 covers the oil inlet 314 to block it. Understandably, the linkage assembly, through the synergistic action of the mechanical structure, achieves automatic opening and closing control of the oil inlet 314, thereby effectively managing the lubricating oil replenishment process. Specifically, the hinge block 315 is fixed to the top of the gear body 1, the opening and closing spring 316 provides elastic force, and the moving block 317 slides along the hinge block 315 under the action of the spring. The hinge rod 318 at its bottom is connected to the oil inlet cap 319. When lubricating oil needs to be added, the oil inlet cap 319 automatically opens under the action of the spring force, and the lubricating oil enters the system through the oil inlet 314. In the non-lubricating state, the oil inlet cap 319 tightly covers the oil inlet 314 to prevent lubricating oil leakage and the entry of external impurities, ensuring the sealing and cleanliness of the lubrication system.

[0040] In one embodiment, such as Figures 1 to 7 As shown, multiple lubrication components 3 are provided, and the multiple lubrication components 3 are distributed in a circumferential array about the center of the rotating sleeve 21. Understandably, by uniformly arranging multiple lubrication components 3 around the center of the rotating sleeve 21, the lubricating oil can more comprehensively cover all tooth surfaces and key parts of the gear body 1, thereby ensuring that the gear is always in a good lubrication state during operation, reducing dry friction and wear between the gear bodies 1, and can also automatically adjust the lubrication frequency under impact force.

[0041] In one embodiment, such as Figure 2As shown, the noise-reducing and shock-resistant gear structure also includes an idler assembly 4. The idler assembly 4 includes an annular groove 41 formed on the outer wall of the rotating shaft sleeve 21, a ring 43 slidably mounted within the annular groove 41, a return spring 42 with its bottom connected between the inner wall of the annular groove 41 and the ring 43, and a positioning bolt 44 fixedly connecting the end face of the ring 43 away from the return spring 42. Understandably, when the gear body 1 is operating normally, the positioning bolt 44 fixes the ring 43 within the annular groove 41, ensuring that the gear body 1 rotates synchronously with the rotating shaft sleeve 21. However, if the gear body 1 fails to operate normally due to an accident (such as tooth breakage or overload), the return spring 42 will push the ring 43 to slide within the annular groove 41, causing the positioning bolt 44 to disengage, thus allowing the gear body 1 to enter an idler state. This design effectively prevents the transmission system from jamming or further damage due to gear failure, protecting the safe operation of the entire mechanical system while reducing maintenance costs and equipment downtime.

[0042] In one embodiment, such as Figure 2 , Figure 8 As shown, the idling assembly 4 further includes a guide member, which includes a connecting rod 45 hinged to the outer wall of the ring 43, and a round rod 46 hinged to the end face of the connecting rod 45 away from the connecting rod 45; the outer wall of the round rod 46 penetrates the inner wall of the gear body 1 and is slidably connected to the gear body 1; the round rod 46 is used to drive the connecting rod 45 to pull the ring 43 to slide in the annular groove 41. Understandably, this mechanical linkage structure can effectively transmit force and motion, ensuring that the gear body 1 is quickly switched to the idling state in the event of a failure.

[0043] In one embodiment, such as Figure 9 As shown, the idling assembly 4 also includes a locking element, which includes a groove 48 formed on the front side of the gear teeth of the gear body 1, a slider 47 slidably mounted in the groove 48, and a spring 49 abutting against the inner wall of the groove 48 and the groove 48; the end of the round rod 46 away from the connecting rod 45 is slidably connected to the slider 47. Understandably, this design further enhances the safety and reliability of the gear structure in fault conditions. When a tooth of the gear body 1 breaks or other faults cause the gear to malfunction, the spring 49 pushes the slider 47 out of the groove 48, thereby triggering the idling mechanism. The movement of the slider 47 drives the round rod 46, which in turn pulls the ring 43 to slide in the annular groove 41 via the connecting rod 45, causing the gear body 1 to enter an idling state.

[0044] In one embodiment, such as Figure 4As shown, multiple circular rods 46 are arranged in a circumferential array about the center of the rotating sleeve 21; and each circular rod 46 is connected to a locking element. Understandably, this significantly improves the reliability and response speed of the idling assembly 4. By evenly arranging multiple circular rods 46 around the center of the rotating sleeve 21 and connecting each circular rod 46 to a locking element, this design ensures that the idling mechanism can be quickly triggered in the event of a fault in any position of the gear body 1. The even distribution of multiple circular rods 46 not only enhances the stability of the mechanism but also improves the sensitivity of fault detection and the efficiency of idling switching through the simultaneous response of multiple locking elements. This design allows the gear structure to enter the idling state more quickly when faced with tooth breakage or other sudden failures, thereby effectively protecting the transmission system from further damage, extending the service life of the equipment, and reducing maintenance costs.

[0045] The present invention also provides a transmission device, including the above-described noise-reducing and shock-resistant gear structure. In the noise-reducing and shock-resistant gear structure of the above embodiments of the present invention, the gear structure includes a gear body 1, a buffer assembly 2 disposed inside the gear body 1, and a noise-reducing assembly 5; an arc-shaped plate 312 is connected to the inner wall of the hollow groove of the gear body 1; the buffer assembly 2 includes a rotating bushing 21 disposed inside the gear body 1, a sliding groove 23 formed on the rotating bushing 21, a plurality of evenly spaced rotating rings 22 slidably mounted in the sliding groove 23 and rotatably connected to the outer wall of the rotating bushing 21, a sliding block 25 connecting adjacent rotating rings 22, and adjacent... A sliding spring 24 is provided between the sliding block 25 and the rotating ring 22; a telescopic rod 26 is fixedly connected to the end face of the sliding block 25 away from the sliding groove 23; a moving spring 27 is fixedly installed in the inner cavity of the telescopic rod 26; and a plurality of fixing brackets 28 are connected to the end face of the telescopic rod 26 away from the sliding block 25. The end face of the fixing bracket 28 away from the telescopic rod 26 is connected to the arc-shaped plate 312. The noise reduction component 5 includes sound-absorbing cotton 51, which is fixedly installed in a plurality of mounting slots formed by the plurality of fixing brackets 28 separating the hollow slots of the gear body 1.

[0046] The working process of the noise-reducing and shock-resistant gear structure in the transmission device of the above embodiments of the present invention is as follows:

[0047] When the gear body 1 starts working, if noise is generated, the sound-absorbing cotton 51 will absorb some of the sound waves, reducing noise propagation. If the gear body 11 is subjected to a large impact force, it will drive the fixed frame 28 to move, thereby squeezing the telescopic rod 26. The squeezed telescopic rod 26 will compress the internal moving spring 27. At the same time, the adjacent telescopic rod 26 will be stretched, causing the sliding block 25 to slide in the sliding groove 23. At this time, the sliding spring 24 is compressed. This series of actions causes the gear body 1 to move eccentrically as a whole, dispersing the impact force and preventing it from acting on the gear body 1 in a concentrated manner, thereby achieving the effect of shock protection.

[0048] After the impact force dissipates, the moving spring 27 releases energy, pushing the telescopic rod 26 to reset; the sliding spring 24 also releases energy, pushing the sliding block 25 back to its initial position. With the reset of the telescopic rod 26 and the sliding block 25, the gear body 11 returns to its initial concentric state and continues to work normally. The entire process, through the compression and reset of the springs, achieves noise reduction and impact protection, thereby effectively protecting the gear body 1.

[0049] When the telescopic rod 26 is compressed, the arc-shaped plate 312 at its top moves accordingly and compresses the pressing column 38. Under pressure, the pressing column 38 moves inward and compresses the second spring 37. At this time, the volume of space within the groove of the moving rod 31 decreases, and the internal pressure increases. This increased pressure acts on the spherical block 310 and the hemisphere 34, but due to the special design of the spherical block 310, only it is pushed, thus opening the opening and allowing air to escape from the left side. Subsequently, the pressure returns to normal, and the spherical block 310 returns to its original position under the action of the spring.

[0050] When the pressing column 38 is released, the second spring 37 returns to its original position, pushing the pressing column 38 outward, thereby resetting the moving rod 31. At this time, the air volume in the groove of the moving rod 31 increases, the pressure decreases, and a negative pressure state is formed. This negative pressure will attract the hemisphere 34 and the spherical block 310, but due to the special design of the hemisphere 34, only it will be drawn away. The lubricating oil from the oil outlet 33 is thus drawn into the groove of the moving rod 31. As the telescopic rod 26 resets, the arc plate 312 also resets, pushing the lubricating oil out of the lubrication port 320 and evenly coating it on the gear tooth surface, thereby achieving gear lubrication and effectively protecting the gear. This process, through the compression and reset of the telescopic rod 26, achieves automatic intake and spraying of lubricating oil, ensuring that the gear always maintains a good lubrication state during operation.

[0051] After prolonged operation, the gear teeth of the gear body 1 may break. Once broken, the top of the groove 48 at the break point will lose its restraint, the locking element at the top of the groove 48 will open, and the pop-out spring 49 will push the slider 47 out of the groove 48. When the slider 47 moves to the bottom of the groove 48, it will cause the round rod 46 to slide. The movement of the round rod 46 is transmitted through the connecting rod 45, causing the ring 43 to move upward in the annular groove 41. This movement causes the positioning pin 44 to disengage from the notch connected to the rotating ring 22, and the return spring 42 is compressed. The upward movement of the ring 43 will also cause all other round rods 46 to move into the groove of the slider 47. Finally, the rotating sleeve 21 can rotate freely, but the rotating ring 22 will idle on the outer wall of the rotating sleeve 21, remaining relatively stationary. Since the rotating ring 22 no longer drives the telescopic rod 26 and the fixed frame 28 to rotate, the gear body 1 enters an idle state, thus preventing the gear from continuing to operate after damage and avoiding further damage to the machine.

[0052] In short, when the gear body breaks, the slider 47 moves out of the slide groove 48 under the action of the pop-out spring 49, which drives the round rod 46 and the connecting rod 45 to move the ring 43 upward, causing the positioning bolt 44 to disengage from the notch of the rotating ring 22, thereby putting the gear body 1 into an idle state, preventing the damaged gear from continuing to run and protecting the machine from damage.

[0053] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention 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 the present invention, and should all be included within the protection scope of the present invention.
