Description
Technical Field
[0001] This utility model relates to the field of gears, specifically to a low-vibration self-lubricating gear assembly for agricultural vehicles. Background Technology
[0002] Low-vibration self-lubricating gear assemblies for vehicles refer to gear assemblies that are specially designed and treated to reduce operating vibration and noise and achieve maintenance-free or low-maintenance automatic lubrication in the transmission systems of agricultural vehicles (such as tractors, harvesters, and agricultural transport vehicles).
[0003] Most existing agricultural vehicle gear components operate in harsh environments, such as bumpy roads and sudden load changes, which cause severe gear impact and vibration, accelerate wear, and generate high-frequency noise. Traditional splash lubrication is easily contaminated and deteriorated in dusty environments, and lubrication failure may lead to dry friction of gears. Therefore, a low-vibration self-lubricating gear component for agricultural vehicles is proposed to address the above problems. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, most agricultural vehicle gear components operate in harsh environments, such as bumpy roads and sudden load changes, which cause severe gear impact and vibration, accelerate wear, and generate high-frequency noise. Traditional splash lubrication is easily contaminated and deteriorated in dusty environments, and lubrication failure may lead to dry friction of gears. This utility model proposes a low-vibration self-lubricating gear component for agricultural vehicles.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a low-vibration self-lubricating gear assembly for agricultural vehicles, including a gear body; a self-lubricating assembly is provided inside the gear body, and a sealing assembly is connected to the outside of the gear body; The self-lubricating component includes an oil reservoir located inside the gear body. The oil reservoir has an annular structure and contains a high-silica fiber cotton core. The high-silica fiber cotton core also has an annular structure. The front end of the oil reservoir has multiple micropores, and the front end of the gear body has a spiral guide groove.
[0006] By incorporating a self-lubricating component and using a high-silica fiber cotton core as the oil storage carrier instead of a free liquid surface, the problem of oil splashing under bumpy conditions in agricultural vehicles is solved. The rotation of the gear body generates centrifugal force, and the oil flows through the variable-diameter micro-holes along the spiral guide groove to the front end face of the gear body. The lubricating oil is released through the cotton core via capillary action, providing self-lubrication to the gear body. Capillary release avoids excessive oil release, extending service life. Furthermore, self-lubrication reduces gear meshing vibration, allowing for continuous lubrication even without external oil supply. The built-in oil storage chamber prevents the lubricating oil from coming into contact with dust, thus preventing contamination of the lubricating oil.
[0007] Preferably, the micropores are arranged in a ring shape, and the micropores are variable diameter micropores.
[0008] Preferably, the inlet diameter of the micropore is 80 μm, the outlet diameter of the micropore is 30 μm, and the outlet end of the micropore is connected to the front end face of the gear body and the spiral guide groove.
[0009] By setting variable diameter micro-orifices, the outlet orifice diameter decreases, the capillary force increases, and the small outlet orifice diameter can keep the outlet flow rate stable, avoiding excessive oil supply.
[0010] Preferably, the sealing assembly includes a central shaft hole located at the center of the gear body, a hub fixedly connected to the front end of the central shaft hole, and a magnetic ring fixedly connected to the front end of the hub.
[0011] Preferably, the front end of the gear body has a slot one and a slot two.
[0012] Preferably, a sealing ring 1 is fixedly fitted inside the first slot, and a sealing ring 2 is fixedly fitted inside the second slot.
[0013] Preferably, sealing nano-graphite sheets are fixedly connected to the front ends of sealing ring one and sealing ring two, and the sealing nano-graphite sheets are in contact with the front end face of the gear body.
[0014] The advantages of this utility model are: 1. This utility model solves the problem of oil splashing under bumpy conditions in agricultural vehicles by setting a self-lubricating component and using a high-silica fiber cotton core as an oil storage carrier instead of a free liquid surface. The rotation of the gear body generates centrifugal force, and the oil flows through the variable diameter micro-holes along the spiral guide groove to the front end face of the gear body. The lubricating oil is released through the cotton core by capillary action, which self-lubricates the gear body. The capillary release avoids excessive oil release and extends service life. In addition, self-lubrication can reduce gear meshing vibration and provide continuous lubrication under the condition of no external oil supply. The built-in oil storage chamber can prevent the lubricating oil from coming into contact with dust and prevent contamination of the lubricating oil. 2. By setting variable diameter micro-orifices, the outlet orifice diameter decreases, the capillary force increases, and the small outlet orifice diameter can keep the outlet flow rate stable, avoiding excessive oil supply.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] This embodiment discloses a low-vibration self-lubricating gear assembly for agricultural vehicles. (Refer to...) Figures 1-6 As shown, it includes a gear body 1; a self-lubricating component 2 is provided inside the gear body 1, and a sealing component 3 is connected to the outside of the gear body 1; The self-lubricating component 2 includes an oil reservoir 201, which is located inside the gear body 1. The oil reservoir 201 has an annular structure and a high-silica fiber cotton core 202 is placed inside the oil reservoir 201. The high-silica fiber cotton core 202 has an annular structure. Multiple microholes 203 are provided at the front end of the oil reservoir 201, and a spiral guide groove 204 is provided at the front end of the gear body 1.
[0020] By setting up a self-lubricating component 2 and using a high-silica fiber cotton core 202 as an oil storage carrier instead of a free liquid surface, the problem of oil splashing under bumpy conditions of agricultural vehicles is solved. The rotation of the gear body 1 generates centrifugal force, and the oil flows through the variable diameter micro-hole 203 along the spiral guide groove 204 to the front end face of the gear body 1. The lubricating oil is released through the cotton core by capillary action, which self-lubricates the gear body 1. The capillary release avoids excessive oil release and extends service life. In addition, self-lubrication can reduce gear meshing vibration and provide continuous lubrication under conditions without external oil supply. Furthermore, the built-in oil storage chamber 201 can prevent the lubricating oil from coming into contact with dust and prevent contamination of the lubricating oil.
[0021] Reference Figures 1-6 As shown, multiple micropores 203 are arranged in a ring, and the micropores 203 are variable diameter micropores 203.
[0022] Reference Figures 1-6 As shown, the inlet diameter of the micro-orifice 203 is 80 μm, the outlet diameter of the micro-orifice 203 is 30 μm, and the outlet end of the micro-orifice 203 is connected to the front end face of the gear body 1 and the spiral guide groove 204.
[0023] By setting the variable diameter micro-orifice 203, the outlet orifice diameter decreases, the capillary force increases, and the small outlet orifice diameter can keep the outlet flow rate stable, avoiding excessive oil supply.
[0024] Reference Figures 1-6 As shown, the sealing assembly 3 includes a central shaft hole 301, which is located at the center of the gear body 1. A hub 302 is fixedly connected to the front end of the central shaft hole 301, and a magnetic ring 303 is fixedly connected to the front end of the hub 302.
[0025] By setting up a magnetic ring 303, metal particles with a diameter >50μm can be captured, and the thermal expansion of the sealed nanographite sheet 308 can compensate for wear gaps.
[0026] Reference Figures 1-6 As shown, the front end of the gear body 1 has a slot 304 and a slot 305.
[0027] Reference Figures 1-6 As shown, a sealing ring 306 is fixedly fitted inside slot 1 304, and a sealing ring 307 is fixedly fitted inside slot 2 305.
[0028] Reference Figures 1-6 As shown, sealing nano-graphite sheets 308 are fixedly connected to the front ends of sealing ring 1 306 and sealing ring 2 307, and sealing nano-graphite sheets 308 are in contact with the front end face of gear body 1.
[0029] The installation of slot 1 304, slot 2 305, and sealing ring 1 306 and sealing ring 2 307 can improve the firmness of the connection between the sealing nano-graphite sheet 308 and the end face of the gear body 1.
[0030] Working principle: High-silica fiber cotton core 202 is used as oil storage carrier instead of free liquid surface to solve the problem of oil splashing under bumpy conditions of agricultural vehicles. The rotation of gear body 1 generates centrifugal force, and oil flows through the variable diameter micro hole 203 along the spiral guide groove 204 to the front end face of gear body 1. The lubricating oil is released through the cotton core by capillary action to self-lubricate gear body 1. Capillary action release avoids excessive oil release and extends service life. In addition, self-lubrication can reduce gear meshing vibration and provide continuous lubrication under the condition of no external oil supply. The built-in oil storage chamber 201 can prevent lubricating oil from contacting dust and prevent contamination of lubricating oil. By setting the variable diameter micro-orifice 203, the outlet orifice diameter decreases, the capillary force increases, and the small outlet orifice diameter can keep the outlet flow rate stable and avoid excessive oil supply. The magnetic ring 303 can capture metal particles with a diameter >50μm, and the sealed nanographite sheet 308 can compensate for wear gaps when heated.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
