Description

Technical Field

[0001] This utility model relates to the field of high-strength impact-resistant gear body technology, specifically a new type of high-strength impact-resistant gear. Background Technology

[0002] Gear drives are widely used in various industries such as mining, machinery, metallurgy, chemical, power, and pharmaceuticals. Using appropriate lubricants and reasonable lubrication methods during gear drive processes is of great significance for effective lubrication protection, extending the service life of the gears, reducing spare parts wear and downtime losses, improving equipment operational stability, and lowering production costs.

[0003] However, when it comes to lubricating the existing gear body, the following lubrication methods are currently widely used in China: Spray lubrication: The principle is to use compressed air to blow the lubricant into a mist through a nozzle, which is then blown onto the tooth surface and distributed. Its advantages are a clean environment, but its disadvantages are relatively high consumption, high viscosity-temperature requirements, and unsuitability for use in harsh northern low-temperature or outdoor environments. Immersion lubrication: It requires less manual labor, has obvious effects, and is low in cost. However, it is wasteful when changing oil after dust leakage and contamination, and the working environment is poor. Spread-on lubrication: This method does not require high equipment conditions, but it is labor-intensive, unevenly applied, unsafe, wasteful, affects the working environment, and is costly.

[0004] In summary, existing mainstream lubrication methods have significant shortcomings in terms of reliability, economy, environmental protection, and safety when dealing with complex and harsh working conditions (such as extreme cold, heavy load, high pollution, and high impact). Insufficient or failed lubrication is often one of the main causes of early gear failure (such as tooth breakage, severe wear, pitting and spalling).

[0005] Therefore, a novel high-strength impact-resistant gear is proposed. Utility Model Content

[0006] The present invention aims to overcome the limitations of the prior art in which oil lubrication is performed when the two gear bodies are meshing during the lubrication of the working gear body, so as to ensure the lubrication quality of the working gear body and effectively utilize and save lubricant.

[0007] A novel high-strength impact-resistant gear is proposed, comprising a gear body, a compression assembly, an oil reservoir, and an oil supply assembly. The oil reservoir and the oil supply assembly are disposed within the gear body, and the oil supply assembly is connected to the oil reservoir, which stores lubricating oil. The compression assembly is disposed at the gear teeth. The compression assembly is compressed under force when the gear body meshes. The oil supply assembly is connected to the compression assembly, and the lubricating oil in the oil reservoir is supplied to the compression assembly via the oil supply assembly. When the gear body meshes, the lubricating oil at the compression assembly is squeezed out onto the meshing surface of the gear body and transmitted to the compression assembly inside the gear teeth, driving the compression assembly to actuate and squeeze the lubricating oil from inside the gear teeth to the meshing surface of the gear teeth. Through the above structural cooperation, the gear body meshing impact force is buffered and the lubricating oil is automatically and on demand supplied.

[0008] In a preferred embodiment of the present invention, the compression assembly includes a buffer plate and a first spring. The top of the buffer plate is connected to the upper tooth surface of the gear teeth, and the first spring is connected between the buffer plate and the upper tooth surface of the gear teeth. The first spring is compressed and stores energy during impact, and automatically resets after engagement and disengagement, thus continuously buffering high-frequency impacts.

[0009] In a preferred embodiment of the present invention, a groove is formed on the tooth groove of the gear body, and a slider is provided in the groove. The slider is connected to the buffer plate, and the slider slides along the groove to ensure the linear movement of the buffer plate and prevent skewing and jamming.

[0010] In a preferred embodiment of the present invention, the buffer plate and the connecting plate are fixed together, and the connecting plate is set on the tooth groove. The connecting plate evenly distributes the impact force to the double buffer plates, thereby expanding the energy absorption range.

[0011] In a preferred embodiment of the present invention, a pressure rod is fixedly connected to one side of the buffer plate. The pressure rod passes through the gear teeth and connects to a pressure plate located inside the oil storage chamber. A first spring connects the pressure plate and the buffer plate. The pressure rod passes through the first spring, and the impact force is transmitted to the pressure plate through the pressure rod, which is converted into a squeezing action on the lubricating oil.

[0012] In a preferred embodiment of the present invention, a first oil-absorbing sponge and a pressure plate are provided in the oil storage cavity. When the pressure plate is squeezed, it can press down on the first oil-absorbing sponge. An oil outlet hole is provided on the side of the oil storage cavity close to the first oil-absorbing sponge. When the pressure plate squeezes the oil-absorbing sponge, lubricating oil seeps out directionally from the oil outlet hole to the meshing surface.

[0013] In a preferred embodiment of the present invention, the oil supply assembly includes an oil injection groove, a third spring, and a second oil-absorbing sponge. The oil injection groove is located inside the gear body, and the third spring and the second oil-absorbing sponge are located inside the oil injection groove. One end of the third spring is connected to the inner wall of the oil injection groove, and the other end is in contact with the second oil-absorbing sponge. When the third spring is placed in the oil injection groove, it is in a compressed state and continuously squeezes the second oil-absorbing sponge. The third spring pushes the second oil-absorbing sponge with constant pressure to ensure that the oil passage is full.

[0014] In a preferred embodiment of the present invention, a cotton rope is provided between the second oil-absorbing sponge and the top of the oil injection tank, and the cotton rope passes through the third spring. The cotton rope mainly serves to guide the flow.

[0015] In a preferred embodiment of the present invention, an oil inlet hole is provided at one end of the oil injection groove. The oil inlet hole is close to the end of the second oil-absorbing sponge. The lubricating oil absorbed by the second oil-absorbing sponge enters the oil storage chamber through the oil inlet hole. The lubricating oil is only squeezed out during impact, with no power loss.

[0016] In a preferred embodiment of the present invention, an oil inlet groove is provided on the gear body. The oil inlet groove is connected to multiple oil injection grooves in the oil supply assembly. When oil is injected from the oil inlet groove, the oil will flow into each oil injection groove along the oil inlet groove, ensuring that the oil supply pressure of each oil injection groove is consistent and improving the uniformity of lubrication.

[0017] The advantages of this utility model compared with the prior art are: The impact force of gear meshing directly drives the extrusion assembly, converting the impact mechanical energy into lubricating extrusion power. Lubricating oil seeps directionally through the oil outlet to the gear meshing point. Extrusion only occurs during impact (the pressure plate squeezes the oil-absorbing sponge), eliminating oil consumption during impact-free periods and reducing waste. The buffer groove and double springs are embedded inside the gear teeth, without increasing the overall size of the gear body. This design converts the harmful impact energy of gear meshing into beneficial lubricating driving force, solving the three major pain points of traditional technologies: high energy consumption, slow response, and complex maintenance caused by the separation of buffering and lubrication. This invention is easy to use, simple in structure, highly adaptable, low in cost, provides excellent lubrication, saves lubricant, and can significantly improve enterprise economic efficiency. It is widely applicable to lubrication projects for large and medium-sized gear bodies in industries such as mining, machinery, metallurgy, chemical, power, and pharmaceuticals.

Detailed Implementation

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model will be described in detail below.

[0020] like Figure 1 As shown, a novel high-strength impact-resistant gear includes a gear body 1, an extrusion assembly 2, and an oil supply assembly 3; the oil supply assembly 3 is disposed on the gear body 1 and includes an oil injection hole 53 for injecting lubricating oil; the extrusion assembly 2 is installed inside the gear teeth of the gear body 1; the oil supply assembly 3 is connected to the extrusion assembly 2.

[0021] The main function of the extrusion assembly 2 is to absorb and dissipate the meshing impact force and protect the gear body structure; it converts the impact force into extrusion force through mechanical linkage, and only squeezes out lubricating oil to the meshing surface when the gear is under meshing force.

[0022] The main function of the oil supply component 3 is to store lubricating oil through the oil filling groove 31 and the second oil-absorbing sponge 33; and to continuously squeeze the second oil-absorbing sponge 33 by utilizing the elastic force of the third spring 32, so that the lubricating oil passes through the oil inlet hole 34 and actively penetrates into the first oil-absorbing sponge 29 in each gear tooth, ensuring a long-term supply of lubricant.

[0023] When the gear bodies 1 mesh with each other, the meshing gear teeth generate a squeezing force, which is transmitted to the squeezing component 2 inside the gear teeth, driving the squeezing component 2 to operate and squeeze the lubricating oil from inside the gear teeth to the meshing surface of the gear teeth.

[0024] Definition: In this embodiment, the direction from the gear body 1 to the teeth is upward, and the opposite is downward.

[0025] like Figure 2 , 3As shown in Figure 4, the extrusion assembly 2 includes a buffer groove 21, a slide groove 211, a slider 212, a buffer plate 22, a first spring 23, a connecting plate 25, a pressure rod 26, a pressure plate 51, a first oil-absorbing sponge 29, and an oil outlet 52. The buffer plate 22 is connected to one end of the first spring 23 and the other end is connected to the gear teeth. The pressure rod 26 passes through the inside of the first spring 26 and then through the gear teeth to connect with the pressure plate 51 inside it. The buffer plate 22 is fixedly connected to the gear teeth of the gear body 1 by a connecting plate 25. The first oil-absorbing sponge 29 is placed in the oil storage cavity 5, and the oil outlet 52 is opened on one side of the gear teeth.

[0026] The buffer groove 21 is mainly the gap between the upper tooth surface of the gear and the buffer plate 22. When the two gear bodies 1 mesh, the gear teeth collide and abut against the buffer plate 22, causing the buffer plate 22 to move backward.

[0027] The buffer plate 22 is a plate with a rectangular cross-section. One end is fixedly connected to the upper tooth surface of the gear teeth, and the other end is connected to the connecting plate 25. The inner surface of the buffer plate 22 is connected to one end of the first spring 23. The inner surface of the buffer plate 22 is connected to the slider 212. When the gear body 1 meshes, the gear teeth squeeze each other, and the buffer plate 22 moves backward to avoid direct contact between the gear teeth of the gear body 1.

[0028] At this time, the first spring 23 is compressed and stores force. The first spring 23 connects the upper tooth surface of the gear tooth to the buffer plate 22, which is located inside the buffer groove 21. The gear body 1 continues to rotate, the pressure on the buffer plate 22 disappears, and the elastic force stored in the first spring 23 is released, so that the buffer plate 22 is reset. The main function of the first spring 23 is to provide elastic buffering, absorb and dissipate part of the impact energy.

[0029] The buffer plate 22 is fixedly connected to the connecting plate 25, which is a rectangular rubber block. When the gear body 1 drives the gear teeth to rotate, the gear teeth abut against the connecting plate 25, so that the gear teeth do not contact the gear body 1, thereby minimizing the noise generated and achieving noise control when the two gear bodies collide.

[0030] The buffer groove 21 is triangular in shape. A sliding groove 211 is provided on the bottom surface of the buffer groove 21. The sliding groove 211 is a rectangular groove. A slider 212 is slidably connected to the inner surface of the sliding groove 211. The slider 212 is a rectangular block. A sliding groove 211 is provided on the side of the connecting plate 25 near the buffer plate 22. The slider 212 connects the buffer plate 22 and the sliding groove 211. The buffer plate 22 is a rectangular plate.

[0031] The pressure rod 26 is a cylindrical rod. One end of the pressure rod 26 is connected to the inner surface of the buffer plate 22, and the other end of the pressure rod 26 is connected to the pressure plate 51. When the two gear bodies 1 mesh, the gear teeth collide and press against the buffer plate 22. The buffer plate 22 squeezes the pressure rod 26, and the pressure rod 26 is squeezed into the first oil-absorbing sponge 29 inside.

[0032] The pressure plate 51 is a rectangular plate, with one side connected to the pressure rod 26 and the other side in contact with the first oil-absorbing sponge 29. When the gear teeth mesh, the pressure rod 26 squeezes the pressure plate 51, and the pressure plate 51 moves toward the first oil-absorbing sponge 29 until the lubricating oil in the first oil-absorbing sponge 29 is squeezed out to flow out of the oil outlet 52.

[0033] The slide groove 211 is formed on the tooth groove of the gear body 1. The slide groove 211 is a rectangular groove, and the inner wall of the slide groove 212 is slidably connected to the slider 212. One end of the slider 212 is fixedly connected to the buffer plate 22. When the two gear bodies mesh, the buffer plate 22 moves backward. Since the slider 212 is slidably connected to the inner surface of the slide groove 211, the slide groove 211 and the slider 212 are stably limited when the buffer plate 22 moves, thereby achieving a stable contact between the gear teeth 1 and the buffer plate 22.

[0034] When the gear body 1 is engaged, the pressure rod 26 will drive the pressure plate 51 to squeeze the first oil-absorbing sponge 29, and the oil in the first oil-absorbing sponge 29 will flow out from the oil outlet 52 to lubricate the gear body 1.

[0035] The extrusion assembly 2 is connected to the oil supply assembly 3. The oil supply assembly 3 injects lubricating oil into the extrusion assembly 2, and then the lubricating oil absorbed in the extrusion assembly 2 is squeezed out through the meshing of the gear body 1, thereby lubricating the gear body 1. The lubricating oil is squeezed out only during impact, with no power loss.

[0036] The oil supply assembly 3 includes an oil injection groove 31, a third spring 32, a second oil-absorbing sponge 33, an oil inlet 34, and an oil-absorbing cotton thread 35. The oil injection groove 31 is located on the hub of the gear body 1. The oil injection groove 31 is a rectangular groove and is mainly used for the internal oil storage chamber to accommodate the second oil-absorbing sponge 33 and the third spring 32.

[0037] The oil filling groove 31 is a rectangular groove, which is opened inside the gear body and distributed in a ring on the gear body 1. One end of it near the gear teeth is provided with an oil inlet hole 34, which is connected to the inside of the oil storage chamber 5, and the other end is connected to the oil filling groove 4.

[0038] Since each oil filling groove 31 is not interconnected, an oil inlet groove 4 is opened on the hub. The oil inlet groove 4 is annular and can connect each oil filling groove 31. An oil inlet hole 34 is opened above it and is located on the surface of the gear body 1. By injecting oil into it, the oil enters the oil inlet groove 4. The lubricating oil in the oil inlet groove 4 enters the oil filling groove 31 through the oil absorption cotton thread 25.

[0039] One end of the oil-absorbing cotton thread 35 is fixed in the common area of ​​the oil injection groove 31 and the oil inlet groove 4, and the other end is fixed on the second oil-absorbing sponge 33. The lubricating oil is drawn into the second oil-absorbing sponge 33 by the oil-absorbing cotton thread 35. The second oil-absorbing sponge 33 is squeezed by the third spring 32, which squeezes the lubricating oil into the oil inlet hole 34.

[0040] One end of the third spring 32 is connected to one end of the oil injection groove 31, and the other end is connected to the second oil-absorbing sponge 33. The oil injection groove 31 is connected to the inside of the gear teeth.

[0041] The usage process of this embodiment: When the gear teeth of the gear body 1 are not in contact with other gear bodies, the compression assembly 2 is in the reset state: the first oil-absorbing sponge 29 is in a relaxed state and has absorbed lubricating oil inside. Under the elastic force of the first spring 23, the buffer plate 22 is located at the outermost side of the buffer groove 21 (close to the meshing surface of the gear teeth), which drives the pressure rod 26 and the pressure plate 51 to retract, squeezing the first oil-absorbing sponge 29 inside the gear teeth 1. The first oil-absorbing sponge 29 is in a compressed state. The third spring 32 remains compressed in the oil injection groove 31, continuously squeezing the second oil-absorbing sponge 33; under this pressure, the lubricating oil in the second oil-absorbing sponge 33 slowly permeates through the oil inlet hole 34 into the first oil-absorbing sponge 29 inside each gear tooth 1, replenishing the oil volume.

[0042] When the teeth of the gear body 1 begin to mesh with the teeth of the mating gear body and press against each other, the meshing force acts directly on the buffer groove 21 area on the surface of the teeth 1. This impact force pushes the buffer plate 22 in the buffer groove 21 to overcome the resistance of the first spring 23 and slide along the slide groove 211 toward the inside of the gear body 1. At this time, the first spring 23 is in a compressed state, absorbing and dissipating part of the impact energy. Simultaneously, the movement of the buffer plate 22 pushes the pressure rod 26, which is fixedly connected to it, forward. The pressure rod 26 drives the pressure plate 51 at its end to move forward and press against the first oil-absorbing sponge 29, which stores lubricating oil inside the gear tooth 1. Under the push of the pressure rod 26, the pressure plate 51 forcefully squeezes the first oil-absorbing sponge 29. The sponge is squeezed, and the lubricating oil absorbed inside is squeezed out. The squeezed-out lubricating oil seeps out through the oil outlet hole 52 opened on the meshing surface of the gear tooth and seeps onto the meshing contact surface of the gear tooth 1 to form a lubricating film, which plays a role in lubrication and reducing friction.

[0043] As long as the gear teeth remain engaged, the extrusion assembly 2 remains in a compressed state. The pressure plate continuously extrudes the first oil-absorbing sponge 29, and lubricating oil continuously seeps out from the oil outlet 52, ensuring lubrication during the engagement process.

[0044] When the gear body is not meshing, the pressure acting on the buffer groove 21 on the surface of the gear teeth disappears, the compressed first spring 23 gradually recovers, and pushes the buffer plate 22 to slide outward along the slide groove 211, returning to the initial position close to the surface of the gear teeth 1; the compressed first spring 26 also gradually recovers, and pushes the buffer plate 22 to move back to the initial position; the reset of the buffer plate 22 causes the pressure rod 26 and the pressure plate 51 to retract backward and leave the first oil-absorbing sponge 29. After the pressure plate 51 stops squeezing, the first oil-absorbing sponge 29 returns to a relaxed state under its own elasticity and no longer leaks oil; at the same time, the first oil-absorbing sponge 29 begins to reabsorb the fresh lubricating oil that continuously permeates from the oil supply component 3 through the oil inlet hole 34, in preparation for the next meshing.

[0045] Regardless of whether the gear body 1 is in a meshing state, the oil supply component 3 works independently. The third spring 32 continuously squeezes the second oil-absorbing sponge 33 in the oil injection groove 31. Under the constant pressure of the third spring 32, the lubricating oil in the second oil-absorbing sponge 33 permeates through the oil inlet hole 34 into the area of ​​the first oil-absorbing sponge 29 inside each gear tooth 1, replenishing the lubricating oil consumed during each meshing and squeezing process. When lubricating oil needs to be added, external lubricating oil is injected through the oil injection hole 53 on the gear body 1 and flows into the oil inlet groove 4. The oil inlet groove 4 distributes the lubricating oil to each oil injection groove 31, where it is absorbed and stored by the second oil-absorbing sponge 33 to maintain the lubricating oil reserve of the entire system.

[0046] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
