Description

Technical Field

[0001] This utility model relates to the field of gear technology, and in particular to a gear with a noise reduction structure. Background Technology

[0002] Gears are mechanical components mainly used to transmit power in various mechanical devices. They transmit motion and power through the meshing of teeth and are one of the basic components of mechanical transmission systems. However, gears generate noise during use, so noise reduction structures are needed to facilitate subsequent use.

[0003] A gear with publication number CN220435353U includes a gear body with a plurality of first teeth spaced apart on its circumference; a plurality of receiving grooves are provided on one side of the plurality of first teeth, and a plurality of second teeth are slidably disposed in the plurality of receiving grooves; an adjusting device is provided on the gear body, which is used to adjust the distance between two adjacent first teeth and second teeth; the adjusting device is also provided with a locking component, which is used to lock the position of the second teeth; when the gear wears and the gap between the gears increases, the adjusting device readjusts the position of the second teeth so that the second teeth can compensate for the gap caused by wear.

[0004] However, the above-mentioned gears still have the following drawbacks when in use: the existing technology does not have the function of noise reduction. Since the gears and shafts are in rigid contact, the gears will generate noise when in use, and this noise will pollute the surrounding environment, thereby reducing the practicality of the gears when in use. Utility Model Content

[0005] The purpose of this invention is to provide a gear with a noise reduction structure to solve the problem mentioned in the background art that existing gears do not have noise reduction function.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear with a noise reduction structure, comprising a gear body and a shaft hole, wherein the shaft hole is provided inside the gear body;

[0007] A noise reduction layer is provided on the outer side of the gear body, a noise reduction block is provided inside the shaft hole, through holes are evenly opened inside the gear body on one side of the shaft hole, and the through holes are filled with noise reduction columns. An oil storage cavity is opened inside the gear body on one side of the through hole, and an oil passage is provided on one side of the oil storage cavity. A lubrication mechanism is provided inside the oil passage. A sealing plug is provided on the front side of the gear body.

[0008] When using a gear with a noise reduction structure according to this technical solution, the noise generated by the gear body during use is reduced by the cooperation of the noise reduction block, the noise reduction column and the noise reduction layer, thereby improving its practicality.

[0009] Preferably, the lubrication mechanism includes a sealing plate disposed inside the oil passage. Baffles are provided on both sides of the top of the sealing plate, and the baffles and the oil passage are fixedly connected. A push rod is fixed to the top of the sealing plate, and a sliding block is fixed to the top of the push rod. A return spring is evenly wound around the outside of the push rod, and one end of the return spring is fixedly connected to the sliding block, while the other end of the return spring is fixedly connected to the sealing plate.

[0010] Preferably, four sliding blocks are provided, which are arranged in a cross shape, and the cross-section of each of the four sliding blocks is semi-circular.

[0011] Preferably, four reset springs are provided, which are arranged in a cross shape, and all four reset springs are in a stretched state inside the oil reservoir.

[0012] Preferably, the noise reduction layer is disposed on the outer side of the gear body, the noise reduction layer is made of nylon, and the outer side of the noise reduction layer is uniformly coated with a wear-resistant coating.

[0013] Preferably, multiple noise reduction columns are provided, each with a circular cross-section, and all of the noise reduction columns are made of aluminum foam, and are arranged in a ring shape.

[0014] Preferably, the noise reduction block has an annular cross-section and is made of a soft material.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the gear with the noise reduction structure not only has a noise reduction function, but also achieves a self-lubricating function;

[0016] By incorporating noise reduction blocks, the rigid contact between the gear body and the bearing is reduced, thereby reducing noise during gear body operation. Additionally, noise reduction columns absorb the noise generated during gear body movement, further reducing noise. Furthermore, the noise reduction layer reduces the rigid contact between the gear body and another gear body, further reducing noise during gear body operation, thus minimizing the impact of noise on the surrounding environment and improving its environmental performance.

[0017] When the two gear bodies mesh with each other, one side of one gear body presses against the sliding block. Under the action of the push rod, the sealing plate moves downward synchronously, thereby allowing the lubricating oil inside the oil storage chamber to be discharged through the oil passage. Through the above operation, the gear body can rotate while automatically applying lubricating oil, thus saving manpower and time and improving its practicality. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5The present invention provides an embodiment of a gear with a noise reduction structure, comprising a gear body 1 and a shaft hole 9. The shaft hole 9 is provided inside the gear body 1, and a noise reduction layer 2 is provided on the outer side of the gear body 1.

[0027] The noise reduction layer 2 is disposed on the outside of the gear body 1. The noise reduction layer 2 is made of nylon and is uniformly coated with wear-resistant paint on the outside of the noise reduction layer 2.

[0028] Specifically, such as Figure 1 , Figure 2 As shown, during use, by applying a wear-resistant coating to the outside of the noise reduction layer 2, the wear resistance of the noise reduction layer 2 can be improved, thereby increasing its service life.

[0029] A noise reduction block 8 is installed inside the shaft hole 9;

[0030] The cross-section of noise reduction block 8 is annular, and the material of noise reduction block 8 is soft material;

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, during use, by setting the noise reduction block 8, the contact between the gear body 1 and the bearing is changed from rigid contact to soft contact, thereby initially reducing the noise generated by the gear body 1 during use.

[0032] The gear body 1 on one side of the shaft hole 9 has through holes 6 evenly opened inside, and the inside of each through hole 6 is filled with noise reduction columns 5.

[0033] There are multiple noise reduction columns 5, each with a circular cross-section and made of aluminum foam. The multiple noise reduction columns 5 are arranged in a ring.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, during use, multiple noise reduction columns 5 are provided to absorb the noise generated by the gear body 1 during use, thereby reducing the propagation of noise and improving its practicality.

[0035] An oil storage chamber 4 is provided inside the gear body 1 on one side of the through hole 6, and an oil passage 3 is provided on one side of the oil storage chamber 4, and a lubrication mechanism 7 is provided inside the oil passage 3.

[0036] The lubrication mechanism 7 includes a sealing plate 705, which is disposed inside the oil passage 3. Both sides of the top of the sealing plate 705 are provided with baffles 702, and the baffles 702 and the oil passage 3 are fixedly connected. A push rod 703 is fixed to the top of the sealing plate 705, and a sliding block 701 is fixed to the top of the push rod 703. A return spring 704 is evenly wound around the outside of the push rod 703, and one end of the return spring 704 is fixedly connected to the sliding block 701, and the other end of the return spring 704 is fixedly connected to the sealing plate 705.

[0037] There are four sliding blocks 701, which are arranged in a cross shape, and the cross-section of each of the four sliding blocks 701 is semi-circular.

[0038] There are four reset springs 704, which are arranged in a cross shape, and all four reset springs 704 are in a stretched state inside the oil reservoir 4.

[0039] A sealing plug 10 is provided on one side of the front of the gear body 1;

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, during use, the sliding block 701 pushes the sealing plate 705 to move downward, thereby allowing the lubricating oil inside the oil storage chamber 4 to be discharged through the oil passage 3, which facilitates the lubrication of the gear body 1. The return spring 704 resets the sealing plate 705 and the baffle 702 to fit together under the action of the push rod 703, thereby sealing the oil passage 3 and preventing the lubricating oil from leaking.

[0041] Working principle: When using this utility model, firstly, by pulling out the sealing plug 10, lubricating oil is easily introduced into the oil storage chamber 4 for storage. When the gear body 1 is in use, since the gear bodies 1 are meshed with each other, the gear body 1 will squeeze the sliding block 701 during use, causing the sliding block 701 to move downward under the squeezing force. At the same time as the sliding block 701 moves downward, the return spring 704 is compressed by the squeezing force. At the same time as the sliding block 701 moves downward, the push rod 703 moves downward synchronously, thereby pushing the sealing plate 705 to move downward, so that the sealing plate 705 moves away from the baffle 702 until one side of the sliding block 701 is retracted into the oil passage 3, thereby allowing the lubricating oil in the oil storage chamber 4 to be discharged through the oil passage 3. Through the above operation, the gear body 1 can be lubricated without affecting its normal use, thereby improving its practicality.

[0042] Then, by setting noise reduction blocks 8 in conjunction with noise reduction layer 2, when gear body 1 contacts bearing and another gear body 1, the rigid contact between gear body 1 and bearing and another gear body 1 is changed to soft contact, thereby reducing the vibration and noise of gear body 1 during use, thus achieving the purpose of initial noise reduction. At the same time, by setting noise reduction columns 5, the material of noise reduction columns 5 is foamed aluminum. This material has a large number of ultra-micro gaps and air bubbles inside, which makes noise reduction columns 5 breathable and porous. When the noise generated by gear body 1 propagates in noise reduction columns 5, it will produce diffuse reflection on the cross-section, resulting in weakening of sound wave propagation, thereby achieving the effect of sound absorption, thereby further reducing the noise generated by gear body 1 during use, and thus improving its environmental friendliness during use.
