Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearings, in particular to a self-aligning roller bearing with a heat dissipation structure. BACKGROUND

[0002] As an important mechanical transmission component, self-aligning roller bearings have a wide range of applications in the industrial field due to their ability to withstand large radial loads and certain bidirectional axial loads. They are often used in crushing equipment for mining machinery, rolling mills for metallurgical equipment, main shafts for heavy machine tools, and other heavy-duty and high-speed operating scenarios, providing critical support for the stable operation of equipment. In these application scenarios, the continuous operation of the equipment has high requirements for the performance of the self-aligning roller bearing. The bearing needs to maintain stable transmission efficiency during long-term operation and be able to adapt to temperature changes during operation. In order to meet these needs, the industry has been optimizing the structure and performance of self-aligning roller bearings, such as improving the adaptability by improving the structural design, enhancing the durability by selecting appropriate materials, etc. Based on the important position of self-aligning roller bearings in industrial applications and the demand for high-performance bearings, the present application proposes a self-aligning roller bearing with a heat dissipation structure, aiming to further improve the comprehensive performance of self-aligning roller bearings in actual applications through targeted structural design, and better adapt to various heavy-duty and high-speed working environments.

[0003] In the prior art, the lubrication method of self-aligning roller bearings has obvious limitations. Traditional bearings mostly use the method of pre-applying lubricating grease in the contact area between the rolling body and the inner and outer rings. There is a lack of dynamic replenishment mechanism. When the bearing is in operation, heat is generated by the friction between the rolling body and the upper and lower contact grooves of the inner and outer rings. As the temperature rises, the pre-applied lubricating grease is prone to loss or failure due to high temperature, while the demand for lubricating grease at the friction site increases, but it cannot be replenished in time, which may easily cause dry friction and aggravate bearing wear. At the same time, the lubricating grease supply of existing bearings cannot adapt to temperature changes. When the temperature of the bearing is low, the lubricating grease has poor flowability, which may cause over-supply and waste of lubricating grease. When the temperature rises and the friction intensifies, it is difficult to increase the supply, and it is impossible to achieve "on-demand replenishment". SUMMARY

[0004] The present application relates to a self-aligning roller bearing with a heat dissipation structure to solve the technical problems raised in the background.

[0005] The application provides a self-aligning roller bearing with a heat dissipation structure.

[0006] Further, the end cover on the left and right sides of the bearing seat body and the bearing seat body are both provided with a sealing ring, and the sealing ring is made of fluorine rubber.

[0007] Further, the bearing seat body is provided with two through holes, and the through holes are provided with connecting bolts for fixing the bearing seat body.

[0008] Further, the upper end of the bearing seat body is provided with an oil injection seat, the oil injection seat is provided with an internal thread, the oil injection seat is screwed with an oil storage seat, the oil storage seat is internally provided with a filter plate for filtering lubricating oil, and the upper end of the oil storage seat is screwed with a rubber cap.

[0009] Further, the inner side of the outer ring is provided with a lower contact groove, and the rolling body is in contact with the lower contact groove and the upper contact groove.

[0010] Further, the outer ring is provided with six heat dissipation grooves in an annular array, and the six heat dissipation grooves are all fixedly provided with three heat dissipation fin plates, and the heat dissipation fin plates are in a honeycomb structure.

[0011] Further, the inner ring and the outer ring are both made of high-carbon chromium bearing steel, and the surfaces of the inner ring and the outer ring are subjected to carburizing and quenching treatment.

[0012] Further, the retainer is made of glass fiber reinforced nylon 66.

[0013] Further, the rolling body is made of ceramic material, specifically, silicon nitride ceramic.

[0014] Further, the heat dissipation pipe is made of red copper.

[0015] The application provides a self-aligning roller bearing with a heat dissipation structure, and has the following beneficial effects: In the application, the tapered heat dissipation hole of the bearing seat end cover is designed to be thick on the inner side and thin on the outer side, so that the probability of external dust entering the bearing interior is reduced, and the aerodynamic principle is used to accelerate the discharge of internal hot air; the hot air flows from the large-diameter end to the small-diameter end under the action of pressure, directional air flow is formed, and the natural heat dissipation efficiency is improved.

[0016] In addition, in the application, the spiral plate of the inner ring and the heat dissipation pipe form an internal heat conduction channel, the spiral plate is attached to the inner wall of the inner ring, the heat generated during the operation of the inner ring can be quickly conducted to the heat dissipation pipe made of red copper (the thermal conductivity of red copper is as high as 401 W / (m·K), which is much higher than that of ordinary metal), the heat dissipation pipe is distributed along the spiral path, the contact area with the internal air is expanded, the heat is transferred to the outer ring and the bearing seat through air convection, and finally discharged through the heat dissipation hole.

[0017] In addition, in the application, the honeycomb-shaped heat dissipation fin plate of the outer ring further strengthens heat dissipation; the honeycomb structure provides a larger heat dissipation surface area under the same volume, and can guide air flow to flow between the fin plates; meanwhile, the gap between the outer ring and the inner wall of the bearing seat forms a secondary heat dissipation space, so that the heat generated by the rolling body friction is quickly transferred to the outside.

[0018] In addition, in the application, the inner ring and the outer ring are made of high-carbon chromium bearing steel subjected to carburizing and quenching, which not only has high strength, but also has good thermal conductivity, so that the internal heat can be quickly transferred; the rolling body is made of silicon nitride ceramic (thermal conductivity of about 30 W / (m·K)), and compared with the traditional steel rolling body, the rolling body has a faster heat dissipation speed and can reduce heat accumulation.

[0019] In addition, in the application, the spiral oil storage cavity inside the rolling body is filled with high-temperature lubricating grease, and its "automatic temperature compensation" feature is deeply matched with the thermal expansion and contraction principle. When the bearing is running, the friction between the rolling body and the upper contact groove of the inner ring and the lower contact groove of the outer ring will generate heat, and the temperature inside the bearing will gradually rise. At this time, the high-temperature lubricating grease in the spiral oil storage cavity will expand in volume due to heating - according to the thermal expansion and contraction characteristics, the intermolecular distance of the lubricating grease increases. Since the spiral oil storage cavity is a closed space, the expanded lubricating grease will generate an outward thrust, flowing along the spiral path to the surface of the rolling body. At the same time, the centrifugal force generated by the rotation of the rolling body further accelerates this process: the lubricating grease moves in the tangent direction of the spiral oil storage cavity under the action of centrifugal force, and finally seeps out through the micro oil outlet hole (supplementary design) on the surface of the rolling body. The dual action of "thermal expansion thrust + centrifugal force" can accurately match the heating condition of the bearing - the higher the temperature (the more intense the friction), the more lubricating grease flows out, which can timely supplement the lubricating grease loss at the friction site and avoid dry friction caused by the failure of lubricating grease due to high temperature. When the bearing stops running or the temperature decreases, the volume of the lubricating grease shrinks, the flow rate automatically decreases, and the remaining lubricating grease flows back to the spiral oil storage cavity for storage, achieving dynamic balance of "on-demand release and oil recovery", which not only ensures the lubrication effect under high temperature conditions, but also avoids excessive consumption of lubricating grease.

[0036] In the embodiment of the application, the end cover 2 on the left and right sides of the bearing seat body 1 is installed with a sealing ring 21 between the end cover 2 and the bearing seat body 1, the sealing ring 21 is made of fluorine rubber, which has excellent elasticity and sealing performance, can tightly adhere to the contact surface on both sides through its elasticity in the connecting gap between the end cover 2 and the bearing seat body 1, and forms a reliable sealing barrier, which can effectively prevent the high-temperature lubricating grease and lubricating oil in the bearing from leaking outward, when the bearing operates in an industrial environment, it is easy to be eroded by external dust, water vapor, oil stains and other pollutants, the fluorine rubber sealing ring 21 can tightly fill the gap between the end cover 2 and the bearing seat, form a physical barrier, prevent pollutants from entering the inside of the bearing through the gap, this protective effect can prevent pollutants from adhering to the contact surface of the rolling body 322, the inner ring 31 or the outer ring 33, prevent abnormal wear caused by friction impurities, also can reduce the risk of part rust caused by water vapor, protect the structural integrity of the bearing body, and the fluorine rubber material itself has excellent high-temperature resistance, the use temperature range can reach-20℃ to 200℃, in the bearing heating process, it will not soften, deform or age failure due to high temperature, can always keep elasticity and sealing performance, compared with ordinary rubber sealing ring 21, its stability in high temperature environment is better.

[0037] In the embodiment of the present application, the upper end of the bearing seat body 1 is provided with an oil injection seat 12, the oil injection seat 12 is provided with an internal thread, the oil injection seat 12 is screwed with an oil storage seat 121, the inside of the oil storage seat 121 is installed with a filter plate 122 for filtering lubricating oil, the upper end of the oil storage seat 121 is screwed with a rubber cap 123, and the rubber cap 123 is used as an elastic component and deforms when pressed to form a certain pressure in the inside of the oil storage seat 121, so that the lubricating oil in the oil storage seat 121 can enter the inside of the bearing through the oil injection seat 12 more quickly, the filling efficiency is improved, and the filling amount of the lubricating oil can be controlled to a certain extent by controlling the pressing force and frequency, so that waste or leakage caused by one-time filling of too much lubricating oil is avoided.

[0038] In the embodiment of the present application, the inner side of the outer ring 33 is provided with a lower contact groove 331, and the rolling body 322 is in contact with the lower contact groove 331 and the upper contact groove 311 respectively, which provides a movement track guide for the rolling body 322, so that the rolling body 322 makes pure rolling movement under the constraint of the contact groove when the inner ring 31 rotates with the shaft, and transverse deviation or falling is avoided, the size precision of the contact groove matches the diameter of the rolling body 322, the shaking of the rolling body 322 during operation is reduced, the relative position between the inner ring 31, the outer ring 33 and the rolling body 322 is stable, additional friction and vibration caused by movement deviation are avoided, the bearing operates more smoothly, the lubricating grease seeping out of the spiral oil storage cavity 3221 in the rolling body 322 forms a lubricating film on the contact surface of the rolling body 322 and the contact groove, the arc-shaped structure of the contact groove can guide the lubricating grease to be uniformly distributed in the contact area, and the direct friction between the rolling body 322 and the inner ring 31 and the outer ring 33 is reduced.

[0039] In the embodiment of the present application, there are six heat dissipation grooves 332 in the annular array on the outer ring 33, and three heat dissipation fins 3321 are fixedly installed in each of the six heat dissipation grooves 332, and the heat dissipation fins 3321 are in a honeycomb structure, which provides a channel for air flow on the one hand, and the surrounding air can form convection between the heat dissipation fins 3321 through the pores when the bearing operates, so as to accelerate heat dissipation; on the other hand, the polyhedral design of the honeycomb structure makes the contact between the fins and the air more uniform, avoids local heat accumulation, and at the same time, the honeycomb structure can form stronger structural support under the same material consumption, which ensures the stability of the heat dissipation fins 3321 and does not excessively increase the weight of the outer ring 33 due to the increase of the fins.

[0040] In the embodiment of the present application, the inner ring 31 and the outer ring 33 are made of high-carbon chromium bearing steel, and the surfaces of the inner ring 31 and the outer ring 33 are subjected to carburizing quenching treatment. The high-carbon chromium bearing steel has a high carbon content, which makes the material inherently have good hardenability and wear resistance. As the core bearing components, the inner ring 31 and the outer ring 33 need to bear the radial and axial loads transmitted by the rolling elements 322. The high strength of the high-carbon chromium bearing steel can ensure that they are not easily deformed or broken under long-term stress, providing a structural basis for the stable operation of the bearing. During operation, the contact grooves of the inner ring 31 and the outer ring 33 are subjected to periodic alternating loads by the rolling elements 322, which can easily produce fatigue cracks. After carburizing quenching, the uniform martensite structure formed on the surface of the high-carbon chromium bearing steel can improve the fatigue strength of the material, delay the generation and propagation of fatigue cracks, and at the same time, this treatment can also refine the grains and reduce internal defects of the material, further improving the service life of the inner ring 31 and the outer ring 33, so that they can adapt to long-term high-frequency operating conditions. In addition, the inner ring 31 and the outer ring 33 need to timely conduct the heat generated by the operation of the rolling elements 322. The high-carbon chromium bearing steel has good thermal conductivity, and the carburizing quenching treatment will not reduce the thermal conductivity of the material, ensuring the smoothness of the heat conduction path, cooperating with the heat dissipation structure to maintain the stability of the internal temperature of the bearing and avoid the influence of high temperature on the material performance.

[0041] In the embodiment of the present application, the retainer 32 is made of glass fiber reinforced nylon 66. Compared with ordinary nylon 66, the tensile strength and bending strength of glass fiber reinforced nylon 66 can be increased by more than 50%. The retainer 32 needs to stably limit the rolling elements 322 in the positioning groove 321 to avoid mutual collision or deviation of the rolling elements 322. This material can withstand the radial pressure and impact force generated during the operation of the rolling elements 322 and is not prone to deformation, ensuring that the rolling elements 322 always roll in the preset track and guaranteeing the stability of the bearing operation. The addition of glass fiber reduces the friction coefficient of the material and enhances the surface wear resistance. The retainer 32, the rolling elements 322, the inner ring 31 and the outer ring 33 all have contact friction. This material can reduce the wear caused by long-term friction and prolong the service life of the retainer 32. In addition, the nylon material itself has a certain self-lubricating property, which can further reduce friction and heat generation in cooperation with the lubricating grease exuded by the rolling elements 322, avoiding the failure of the retainer 32 due to excessive heat caused by friction. Nylon 66 has a certain elasticity, and after being reinforced by glass fiber, it still retains a certain toughness. Compared with metal retainers 32, it can better absorb the vibration and impact of the rolling elements 322 during operation. When the rolling elements 322 collide with the positioning groove 321, this material can buffer the impact force through slight deformation, reduce the noise caused by metal impact, and make the bearing operate more smoothly and quietly.

[0042] In the second embodiment, the rolling body 322 is made of ceramic material, specifically silicon nitride ceramic, which has a hardness of HRC 78-82, much higher than steel rolling body 322, and its wear resistance is 3-5 times that of traditional bearing steel. When the rolling body 322 rolls between the contact grooves of the inner and outer rings 33, it can effectively resist frictional wear between the contact grooves, reduce surface wear, and has excellent impact toughness, which is not easy to crack or peel off when subjected to radial and axial combined load, even under heavy load conditions, it can maintain structural integrity, greatly extending the replacement cycle of the rolling body 322. The thermal conductivity of silicon nitride ceramic is higher than that of bearing steel, which can quickly conduct the friction heat generated by the contact between the rolling body 322 and the inner and outer rings 33, and cooperate with the heat dissipation grooves 332 of the outer ring 33 and the heat dissipation pipes 315 of the inner ring 31 to accelerate the dissipation of heat inside the bearing, avoid the failure of the surrounding lubricating grease due to the heat accumulation of the rolling body 322, and further improve the heat dissipation efficiency of the bearing.

[0043] In the third embodiment, the heat dissipation pipe 315 is made of red copper material, which has the following effects: the heat dissipation pipe 315 is distributed along the spiral plate 314 on the inner ring 31, which can directly contact the inner ring 31 and the surrounding parts. When the bearing is running, the heat generated by the friction between the inner ring 31 and the rolling body 322 will be quickly transferred to the red copper heat dissipation pipe 315, and then spread outward through the pipe wall, realizing the efficient heat dissipation process of "heat capture-directional conduction". The spiral distribution of the heat dissipation pipe 315 along the spiral plate 314 increases the contact area with the air inside the inner ring 31. At the same time, when the bearing is running, the air inside the inner ring 31 forms a circulation due to centrifugal force, and the spiral heat dissipation pipe 315 can guide the airflow to flow along the pipe wall, accelerating the exchange of heat and air. In addition, the spiral path prolongs the "effective travel" of heat conduction, allowing heat to be more fully dissipated to the surrounding environment during transmission, avoiding local heat accumulation.

[0044] Working principle of the application: when the self-aligning roller bearing with heat dissipation structure of the application is working, the inner ring 31 rotates synchronously with the shaft, and the outer ring 33 is fixed through the bearing seat body 1. When the inner ring 31 rotates, the rolling body 322 is rolled in the positioning groove 321 of the retainer 32, and the rolling body 322 is in contact with the upper contact groove 311 of the inner ring 31 and the lower contact groove 331 of the outer ring 33 at the same time, so as to realize the rotation of the inner ring 31 relative to the outer ring 33 and transmit the load. The arc-shaped structure of the upper and lower contact grooves 331 is matched with the curved surface of the rolling body 322, so as to disperse the load and realize self-alignment through the angle fine adjustment of the rolling body 322 when the shaft is slightly bent or installed with deviation. The heat generated by the bearing operation is dissipated through the heat dissipation system. The heat dissipation pipe 315 made of red copper on the inner ring 31 quickly absorbs the heat of the inner ring 31 along the spiral path, and the heat dissipation groove 332 and the honeycomb-shaped heat dissipation fin plate 3321 of the outer ring 33 collect the heat of the outer ring 33 and diffuse through the gap between the fin plates. The heat of the inner ring 31 and the outer ring 33 is partially transmitted to the bearing seat body 1, and then discharged through the conical heat dissipation hole 22 of the end cover 2 by utilizing the "chimney effect", and partially radiated through the outer wall of the bearing seat and the heat dissipation fin group. The lubrication system continuously lubricates through "built-in grease storage + external grease supplement". The high-temperature lubricating grease in the internal spiral oil storage cavity 3221 of the rolling body 322 seeps out to form a lubricating film due to thermal expansion and contraction. The lubricating oil in the oil storage seat 121 is filtered through the filter plate 122 and then supplemented through the oil supply pipe. The rubber cap of the pressing rubber cap cover 123 can also actively supplement the grease. At the same time, the fluorine rubber sealing ring 21 between the end cover 2 and the bearing seat realizes sealing protection, and the connection flange and the connection bolt of the bearing seat and the threaded connection between the oil storage seat 121 and the oil injection guarantee the stability of the structure. Finally, through the circulation of "load transmission-heat generation by friction-heat dissipation and cooling-lubrication and wear reduction", self-alignment and sealing protection, high efficiency, stability and long service life are realized, and the high temperature and heavy load working conditions are adapted.

[0046] 2. In the case of no conflict, the embodiments of the application and the features in the embodiments can be combined to obtain new embodiments.

[0047] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the application, which should be covered within the protection scope of the application.
