Description
Technical Field
[0001] The present invention relates to the field of sprockets, and specifically to a sprocket capable of eliminating transmission fluctuations. Background Art
[0002] In modern mechanical transmission systems, chain drive, as an important transmission method, is widely used in various mechanical equipment such as bicycles, motorcycles, industrial production equipment, and agricultural machinery due to its advantages of simple structure, high transmission efficiency, and strong adaptability. The chain drive system mainly consists of a sprocket and a chain. The sprocket, as the driving wheel or the driven wheel, meshes with the chain links through its tooth crests to achieve the transmission of power or motion. However, during the long-term operation of the chain drive system, the following problems will occur in the meshing process between the tooth crests of the sprocket and the chain: During the meshing process of the sprocket and the chain, due to relative motion and contact pressure, slight wear will occur on the surfaces of the tooth crests and the chain links. This wear will damage the original lubricated surface, making it difficult to form and maintain the lubricating oil film. As the wear intensifies, the gap between the tooth crests and the chain increases, and the contact area also changes, further affecting the lubrication effect. When the lubrication between the tooth crests and the chain is reduced to a certain extent, it will have a serious negative impact on the normal operation of the chain drive system. Insufficient lubrication will increase the friction between the tooth crests and the chain, resulting in uneven resistance on the chain during operation. This uneven resistance will cause the chain to fluctuate, thus making the rotation speed of the sprocket unstable and affecting the accuracy and reliability of the transmission. For this reason, we propose a sprocket capable of eliminating transmission fluctuations. Summary of the Invention

The plugging pipe is slidably connected in the oil dripping groove and the outer wall of the plugging pipe is completely attached to the inner wall of the oil dripping groove.
[0008] Preferably, the quantitative lubrication assembly further includes an opening groove, a linkage rod, and a triangular frame. An opening groove is provided on one side of each of the two oil dripping boxes facing away from the circular partition. A linkage rod is slidably installed in the opening groove. One end of the linkage rod is fixedly connected to the outer wall of the plugging pipe near the bottom position. The other end of the linkage rod extends out of the opening groove and is sleeved with a triangular frame.
[0009] Preferably, the triangular frame is in an isosceles triangle shape and is horizontally arranged.
[0010] Preferably, the quantitative lubrication assembly further includes fixed rods, transmission rods, convex columns, and rubber rollers. Two symmetrically arranged fixed rods are fixedly connected to the sides of the sprocket A and sprocket B facing away from the convex rings. The ends of the fixed rods extend out of the anti-leakage ring. Transmission rods extending to the outer wall of the sealing ring are fixedly connected to the ends of the two fixed rods. Convex columns are fixedly connected to the outer wall of the transmission rod near the end position. Rubber rollers are rotatably sleeved on the ends of the convex columns facing away from the transmission rod corresponding to the outer wall edge of the sealing ring.
[0011] Preferably, the oil dripping box is fixedly connected to the lubricating oil tank through a lubricating oil delivery pipe. An oil storage cavity extending into the oil dripping groove is provided on one side of the oil dripping box close to the lubricating oil tank. The oil storage cavity is inclined, and one end of the lubricating oil delivery pipe covers the outside of the oil storage cavity.
[0012] Preferably, the reducing fluctuation assembly includes a long rod, an assembly box, an end groove, and wear-resistant extrusion parts. A long rod extending to the bottom of the bridge is fixedly connected to the top of the bridge. Assembly boxes are fixedly connected to the top and bottom ends of the long rod.

[0013] Compared with the prior art, the present invention provides a sprocket capable of eliminating transmission fluctuations, having the following beneficial effects: 1. For the sprocket capable of eliminating transmission fluctuations, through components such as a tripod, a linkage rod, a plugging pipe, and a return spring, precise quantitative addition of lubricating oil is achieved. When the rubber roller on the transmission rod rotates to the bottom of the tripod, it pushes the tripod upward, thereby driving the plugging pipe to rise, causing the lubricating oil in the oil storage cavity to flow into the drip trough under the guidance of the inclined lubricating oil delivery pipe, and dripping onto the meshing part of the sprocket and the chain. When the rubber roller slides past the tripod, the return spring resets the plugging pipe to re-plug the oil storage cavity. This precise quantitative lubrication method not only ensures the lubrication effect but also avoids waste of lubricating oil, effectively extending the service life of the chain drive system.
[0014] 2. For the sprocket capable of eliminating transmission fluctuations, the quantitative lubrication component can automatically perform lubrication operations as the sprocket rotates without manual intervention. As long as there is enough lubricating oil in the lubricating oil tank, the system can continuously lubricate the sprocket and the chain, achieving real-time automatic lubrication. This not only reduces the maintenance cost but also improves the operation stability of the equipment and reduces the probability of failures caused by insufficient lubrication.
[0015] 3. For the sprocket capable of eliminating transmission fluctuations, through the sealing ring and the anti-leakage ring, it can effectively prevent the lubricating oil from dripping outside the sealing ring. At the same time, the surrounding structure of the sealing ring reduces the noise during the rotation of the sprocket, and the lubricating oil splashed on the inner wall of the sealing ring flows through the inner wall to the bottom inner wall for collection. This design effectively avoids the splashing and leakage of lubricating oil, reduces environmental pollution, and is also convenient for recycling the collected lubricating oil, further reducing the cost.
[0016] 4. For the sprocket capable of eliminating transmission fluctuations, through the cooperation of components such as a long rod, a component box, an end groove, and wear-resistant extrusion parts, the chain is adjusted during transmission. When the chain continuously transmits in the transmission hole, the pin shaft on the chain is downwardly extruded by several groups of wear-resistant extrusion parts, making the chain in a relatively tight state during transmission, thereby reducing the fluctuations during chain transmission. This setting effectively improves the transmission accuracy and reliability of the chain drive system, enabling the equipment to operate more stably.
[0017] 5. For the sprocket capable of eliminating transmission fluctuations, through the drip trough and the dripping method, the lubricating oil can be accurately dripped at the key position where the sprocket and the chain mesh. When the plugging pipe rises driven by the linkage rod, the lubricating oil flows from the inclined oil storage cavity through the lubricating oil delivery pipe into the drip trough. Due to the optimized design of the position and shape of the drip trough, the lubricating oil can be evenly distributed on the contact surface between the tooth crest of the sprocket and the link of the chain, forming a uniform lubricating oil film. This optimized lubrication distribution method effectively reduces friction and wear, improves the transmission efficiency, and enables the chain drive system to operate more efficiently.
[0018] 6. The sprocket capable of eliminating transmission fluctuations can prevent external dust and other impurities from entering the internal chain drive system through the settings of the sealing ring and the anti-leakage ring, protect the cleanliness of the lubricating oil, and ensure that the lubricating performance is not affected.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1-9, a sprocket capable of eliminating transmission fluctuations, comprising a sprocket A1 and a sprocket B2, the sprocket A1 and the sprocket B2 being connected by a chain 3, one side of the sprocket A1 and the sprocket B2 being fixedly connected with an integrated convex ring 4, the outer walls of the two groups of convex rings 4 being rotatably sleeved with a circular partition 5, one side of the two groups of circular partitions 5 being fixed with multiple groups of mounting blocks 6 for mounting the circular partitions 5, during installation: several groups of mounting blocks 6 on the circular partitions 5 provide mounting positions for the circular partitions 5, the two groups of circular partitions 5 are fixed, the other sides of the two groups of circular partitions 5 are fixedly connected with sealing rings 7, the tops of the two groups of sealing rings 7 are respectively fixedly installed with oil drip boxes 11 directly above the sprocket A1 and the sprocket B2, the tops of the sealing rings 7 are fixedly installed near the side of the oil drip box 11 for storing lubricating oil, the two groups of sealing rings 7 are fixedly connected by a bridge 28, and further comprising: The quantitative lubrication component is set on the sealing ring 7 to enhance the lubrication between the sprocket A1 and the sprocket B2 and the chain 3. The fluctuation reduction component is arranged on the bridge 28 and is used to eliminate the fluctuation of the chain 3 during operation.
[0023] Transmission holes 10 for the chain 3 to pass through are respectively opened near the top and the bottom of the two sets of sealing rings 7 on the side close to each other.
[0024] The two sets of sealing rings 7 are both annular in shape. A leak-proof ring 8 is fixedly connected to the side of the inner wall of the sealing ring 7 away from the circular partition 5 to prevent the lubricating oil from leaking. The lubricating oil tank 12 inputs lubricating oil into the oil storage cavity 20 through the lubricating oil pipe 13. The lubricating oil provides lubrication for the sprocket A1 and the sprocket B2 when they are engaged with the chain 3 and reduces the noise of the chain 3 during transmission. The sealing ring 7 prevents the sprocket A1 and the sprocket B2 from being thrown out during rotation. The lubricating oil thrown on the inner wall of the sealing ring 7 flows through the inner wall of the sealing ring 7 to the bottom inner wall of the sealing ring 7 for collection. The leak-proof ring 8 inside the sealing ring 7 prevents the lubricating oil from dripping out of the sealing ring 7. The surrounding of the sealing ring 7 reduces the noise when the sprocket A1 and the sprocket B2 rotate.
[0025] The quantitative lubrication assembly includes a side protection frame 14, a top cover 15, a straight rod 16, a plugging pipe 17, a return spring 18 and an oil dripping groove 19. Two sets of side protection frames 14 are fixedly connected to the tops of two sets of oil dripping boxes 11. A top cover 15 is fixedly connected between the tops of the two sets of side protection frames 14. A straight rod 16 is fixedly connected to the position corresponding to the center of the bottom of the top cover 15. A plugging pipe 17 is sleeved on the outer wall of the straight rod 16. A return spring 18 is sleeved on the outer wall of the straight rod 16 between the plugging pipe 17 and the top cover 15. The bottom of the oil dripping box 11 extends into the sealing ring 7. An oil dripping groove 19 extending to the bottom of the oil dripping box 11 is fixedly connected between the two sets of side protection frames 14 corresponding to the top of the oil dripping box 11. The plugging pipe 17 is slidably connected in the oil dripping groove 19 and the outer wall of the plugging pipe 17 is completely attached to the inner wall of the oil dripping groove 19. The plugging pipe 17 gradually slides upward in the oil dripping groove 19 through the movement of the linkage rod 22. While the plugging pipe 17 slides on the straight rod 16, it gradually compresses the return spring 18. When the bottom of the plugging pipe 17 slides past the position of the oil storage cavity 20, due to the lack of plugging of the plugging pipe 17 at one end of the oil storage cavity 20, the lubricating oil in the oil storage cavity 20 flows into the oil dripping groove 19 due to the inclined setting of the oil storage cavity 20. The lubricating oil drips through the oil dripping groove 19 to the position where the sprocket A 1 and the sprocket B 2 are engaged with the chain 3.
[0026] The quantitative lubrication assembly further includes an opening groove 21, a linkage rod 22 and a tripod 23. An opening groove 21 is provided on one side of each of the two sets of oil dripping boxes 11 facing away from the circular partition 5. A linkage rod 22 is slidably installed in the opening groove 21. One end of the linkage rod 22 is fixedly connected to the outer wall of the plugging pipe 17 near the bottom. The other end of the linkage rod 22 extends out of the opening groove 21 and is sleeved with a tripod 23.
[0027] The tripod 23 is in the shape of an isosceles triangle and is horizontally arranged. The horizontal arrangement of the tripod 23 can keep it in a stable contact state with the rubber roller 27 during the entire circular motion process. When the sprockets 1 and 2 rotate, the rubber roller 27 will continuously contact and push the tripod 23. If the tripod 23 is not horizontal, poor contact may occur at some positions, resulting in the rubber roller 27 being unable to effectively push the tripod 23 upward, thereby affecting the normal supply of lubricating oil. The horizontal arrangement can ensure that during the rotation of the rubber roller 27, a stable extrusion force is always applied to the tripod 23, enabling the linkage rod 22 and the plugging pipe 17 to move in the expected manner and maintaining the normal operation of the lubrication system.
[0028] The quantitative lubrication assembly also includes a fixed rod 24, a transmission rod 25, a boss 26 and a rubber roller 27. Two groups of symmetrically arranged fixed rods 24 are fixedly connected on the side of the sprocket A1 and the sprocket B2 away from the convex ring 4. The ends of the fixed rods 24 extend outside the leak-proof ring 8. The end positions of the two groups of fixed rods 24 are fixedly connected to the transmission rods 25 extending to the outer wall position of the sealing ring 7. The outer wall of the transmission rod 25 is fixedly connected with a boss 26 near the end position. The end of the boss 26 away from the transmission rod 25 corresponds to the outer wall edge of the sealing ring 7 and is rotatably sleeved with a rubber roller 27. After lubrication is completed, the sprocket A1 is The main purpose of gradually accelerating the rotation is to enable the equipment to reach normal working speed, meet actual work needs, and improve work efficiency. When in use, first rotate the sprocket A1 slowly. The sprocket A1 drives the sprocket B2 to rotate synchronously through the chain 3. The fixed rod 24 on the sprocket A1 and the sprocket B2 drives the transmission rod 25 to rotate synchronously. When the rubber roller 27 on the transmission rod 25 gradually rotates to the bottom position of the tripod 23, the tripod 23 is squeezed upward by the rubber roller 27 and drives the linkage rod 22 to slide upward in the open groove 21. In the low-speed lubrication stage, the equipment is mainly to ensure that the key parts of the chain and sprocket are fully and evenly lubricated to form a good lubricating oil film. The accelerated rotation can further test whether the fluctuation of the chain during transmission is effectively improved after lubrication, ensuring that the chain transmission system can still work stably at the normal operating speed of the equipment, reducing equipment failures caused by insufficient lubrication or transmission fluctuations, and ensuring reliable operation of the equipment. When the rubber roller 27 slides over the bottom of the tripod 23, the return spring 18 squeezes the blocking tube 17 downward through its own extrusion force, and the linkage rod 22 returns to its initial position in the open groove 21 through the blocking tube 17. After returning to the initial position, the blocking tube 17 continues to block the oil storage cavity 20 to prevent the lubricating oil in the oil storage cavity 20 from leaking.
[0029] The oil drip box 11 is fixedly connected to the lubricating oil tank 12 by a lubricating oil pipe 13. An oil storage cavity 20 extending into the oil drip groove 19 is provided on one side of the oil drip box 11 close to the lubricating oil tank 12. The oil storage cavity 20 is arranged at an angle, and one end of the lubricating oil pipe 13 covers the outside of the oil storage cavity 20.
[0030] The fluctuation reduction component includes a long rod 29, a component box 30, an end groove 31, and a wear-resistant extrusion piece 9. The top of the bridge frame 28 is fixedly connected with a long rod 29 extending to the bottom of the bridge frame 28. Component boxes 30 are fixedly connected to both the top and bottom ends of the long rod 29. End grooves 31 are formed in the two groups of component boxes 30. A number of wear-resistant extrusion pieces 9 arranged in an inclined shape are fixedly connected to the top inner wall of the end groove 31. After lubrication is completed, the sprocket A1 is gradually accelerated to rotate. During the transmission of the chain 3, the pin shafts on the chain 3 are downwardly extruded by a number of wear-resistant extrusion pieces 9, so that the chain 3 is in a relatively tight state during transmission, reducing the fluctuation during the transmission of the chain 3. When continuous transmission occurs in the transmission holes 10 inside the chain 3, the chain 3 prevents the lubricating oil from being thrown out through the transmission holes 10 due to the blockage of the chain 3.
[0031] Working principle: During installation: Several groups of mounting blocks 6 on the circular partition 5 provide mounting positions for the circular partition 5 and fix the two groups of circular partitions 5. When in use, first, slowly rotate the sprocket A1. The sprocket A1 drives the sprocket B2 to rotate synchronously through the chain 3. The fixed rods 24 on the sprocket A1 and the sprocket B2 drive the transmission rod 25 to rotate synchronously. When the rubber roller 27 on the transmission rod 25 gradually rotates to the bottom position of the tripod 23, the tripod 23 is driven by the upward extrusion force of the rubber roller 27 to drive the linkage rod 22 to slide upward in the opening groove 21. The blocking pipe 17 gradually slides upward in the oil dripping groove 19 through the movement of the linkage rod 22. While the blocking pipe 17 slides on the straight rod 16, it gradually squeezes the return spring 18. When the bottom of the blocking pipe 17 slides past the position of the oil storage cavity 20, since one end of the oil storage cavity 20 lacks the blockage of the blocking pipe 17, the lubricating oil in the oil storage cavity 20 flows into the oil dripping groove 19 due to the inclined setting of the oil storage cavity 20. The lubricating oil drips through the oil dripping groove 19 to the meshing position of the sprocket A1, the sprocket B2 and the chain 3. After the rubber roller 27 slides past the bottom of the tripod 23, the return spring 18 squeezes the blocking pipe 17 downward through its own extrusion force. The linkage rod 22 returns to the initial position in the opening groove 21 through the blocking pipe 17. After returning to the initial position, the blocking pipe 17 continues to block the oil storage cavity 20 to prevent the leakage of the lubricating oil in the oil storage cavity 20. The lubricating oil tank 12 inputs lubricating oil into the oil storage cavity 20 through the lubricating oil delivery pipe 13. The lubricating oil provides a lubricating effect for the meshing of the sprocket A1, the sprocket B2 and the chain 3 and reduces the noise during the transmission of the chain 3. The sealing ring 7 prevents the lubricating oil from being thrown outwards when the sprocket A1 and the sprocket B2 rotate. The lubricating oil thrown on the inner wall of the sealing ring 7 flows into the bottom inner wall of the sealing ring 7 through the inner wall of the sealing ring 7 for collection. The anti-leakage ring 8 in the sealing ring 7 prevents the lubricating oil from dripping out of the sealing ring 7. The enclosure of the sealing ring 7 reduces the noise during the rotation of the sprocket A1 and the sprocket B2. When the lubrication is completed, then gradually accelerate the rotation of the sprocket A1. During the transmission of the chain 3, the pin shafts on the chain 3 are squeezed downward by several groups of wear-resistant extrusion parts 9, so that the chain 3 is in a relatively tight state during transmission, reducing the fluctuation during the transmission of the chain 3. When continuously transmitting in the transmission hole 10 in the chain 3, since the chain 3 blocks, it prevents the lubricating oil from being thrown outwards through the transmission hole 10.
