Description

Technical Field

[0001] The present invention relates to the technical field of bearing seats, and specifically to a highly stable, energy-saving and noise-reducing bearing seat. Background Art

[0002] In the modern industrial field, as a key basic component for supporting rotating shafts in mechanical equipment, the performance of bearing seats directly determines the operating efficiency, energy consumption level and service life of the equipment. From precision instruments to large industrial equipment, from automobile manufacturing to power generation, the stable operation of bearing seats is the core element to ensure production continuity and product quality. Currently, many problems have emerged in the actual operation of traditional bearing seats widely used in the market. In terms of the lubrication system, most bearing seats still rely on regular manual oil injection or simple oil bath lubrication methods. Taking the production equipment of a large machinery manufacturing enterprise as an example, the bearing seats using manual oil injection need to be lubricated and maintained once every two weeks on average. This not only consumes a large amount of labor costs, but also is difficult to accurately control the oil injection volume, often resulting in under-lubrication or over-lubrication. According to statistics, bearing failures caused by improper lubrication account for more than 35% of the total equipment failures. Although oil bath lubrication can achieve a certain degree of automatic lubrication, the lubricating oil cannot be effectively recycled, and the consumption of lubricating oil for a single replacement is 2-3 times that of an efficient circulating lubrication system, causing serious waste of resources and cost increase. More critically, during long-term operation, impurities such as external dust and metal debris are extremely likely to mix into the lubricating oil, and traditional bearing seats lack effective impurity filtration and separation mechanisms. These impurities will exacerbate the wear of the bearings, shorten the service life of the bearings, and seriously affect the reliability of the equipment; In terms of noise reduction and stability, the performance of traditional bearing seats is also unsatisfactory. Due to insufficient lubrication or uneven lubrication, the bearings will generate high-frequency vibrations and harsh noises when rotating at high speeds. In equipment sensitive to noise such as textile machinery and fans, the noise generated by traditional bearing seats often exceeds 85 decibels, which not only seriously affects the working environment and the physical and mental health of operators, but also may cause loosening of equipment parts due to vibrations caused by the noise, reducing the operating stability of the equipment; Although some enterprises have tried to solve the above problems by improving the bearing structure or optimizing the lubrication method, such as using a sealed structure to prevent impurities from entering, or using high-viscosity lubricating oil to enhance the lubrication effect, these improvement measures are often only partial optimizations and cannot fundamentally solve the problems of lubricating oil recycling, impurity separation and adaptive lubrication. Summary of the Invention

[0003] The object of the present invention is to provide a highly stable, energy-saving and noise-reducing bearing housing, so as to solve the problems of high labor cost for manual oil injection, difficult precise control of the oil injection volume, serious waste of lubricating oil in oil bath lubrication, bearing wear caused by the lack of an effective impurity filtration and separation mechanism, large noise caused by lubrication problems, poor operating stability of the equipment, and the inability of existing improvement measures to achieve the recycling of lubricating oil and adaptive lubrication as mentioned in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a highly stable, energy-saving and noise-reducing bearing housing, including a base. The upper end of the base is fixedly installed with a gland through bolts. A rotating inner ring is installed between the gland and the base. Oil collecting grooves are formed on the upper surfaces at both ends of the base, and a filter screen is fixedly arranged at the upper end of the oil collecting groove. A self-lubricating mechanism is arranged on the upper end of the base. By extruding and lubricating the lubricating oil liquid in the way of the rotation of the inner ring during the rotation process, and cooperating with the subsequent recovery and static impurity removal of the lubricating oil liquid, long-term efficient lubrication is realized to reduce noise and improve the working stability. The self-lubricating mechanism includes: a functional sleeve, which is slidably installed on the outer surface of one end of the inner ring. A connection groove is formed on the outer surface of one end of the functional sleeve. An electric push rod is fixedly installed on the upper surface of one end of the base, and a displacement dial rod is fixedly connected to one end of the electric push rod. An extrusion groove is formed on the outer surface of the functional sleeve. An installation barrel is fixedly arranged on the upper surface of the base, and a sliding extrusion rod is installed at the upper end of the installation barrel. A rotating contact wheel is installed at the upper end of the extrusion rod. A liquid storage box is fixedly installed on the upper surface of the base on one side of the installation barrel. A liquid injection port is fixedly arranged on the outer surface of the upper end of the gland, and one end of the liquid injection port penetrates through the inner surface of the gland. An air inlet pipe is connected between the upper end of the liquid storage box and the lower end of the installation barrel, and an air inlet groove is formed between the upper end of the air inlet pipe and the inner bottom surface of the installation barrel. An overflow box is fixedly arranged inside the liquid storage box. A liquid outlet check valve is fixedly installed at the upper end of the liquid storage box, and the lower end of the liquid outlet check valve is designed as a tubular shape. First precipitation pipes and second precipitation pipes are fixedly arranged on the outer surface of the tubular lower end of the liquid outlet check valve. A liquid injection port is fixedly arranged inside the tubular lower end of the liquid outlet check valve. A first baffle plate is fixedly arranged on the inner surface of the lower end of the liquid outlet check valve above the liquid injection port. A first flow baffle plate and a second baffle plate are fixedly arranged at the connection between the lower end of the liquid outlet check valve and the upper end of the first precipitation pipe. A liquid injection pipe is connected between the liquid injection port and the liquid outlet check valve. A liquid inlet check valve is fixedly installed on the side surface of the lower end of the liquid storage box, and one end of the liquid inlet check valve is fixedly connected to one end of a liquid suction pipe, and the other end of the liquid suction pipe penetrates through the filter screen and is located inside the oil collecting groove. A follow-up adjustment mechanism is arranged on the outer surfaces of the functional sleeve and the electric push rod to adaptively adjust the output volume of the lubricating oil by real-time monitoring of the rotation speed of the inner ring. The follow-up adjustment mechanism includes: a sliding cylinder fixedly arranged on the outer surface of one end of the functional sleeve. A sliding contact plate is installed at one end of the functional sleeve, and a guiding groove is formed on the outer surface of the contact plate. A sliding mounting cylinder is installed on the outer surface of the electric push rod, and a sliding guiding rod is installed inside one end of the mounting cylinder. A proximity sensor is fixedly installed inside the mounting cylinder.

[0005] Preferably, the lower ends of the two oil collecting grooves are communicated with each other. The functional sleeve is concentric with the inner ring. One end of the displacement lever is snap-fitted into the connecting groove, and a rotating ball is installed on the outer surface of the end of the displacement lever connected to the connecting groove.

[0006] With the above technical solution, the communication of the lower ends of the two oil collecting grooves enables the lubricating oil to flow and converge more smoothly at both ends of the base, facilitating unified recovery and treatment, and avoiding local accumulation or loss of the lubricating oil. The concentric setting of the functional sleeve and the inner ring ensures the stability of the functional sleeve during the rotation with the inner ring, thereby ensuring the effective cooperation between the extrusion groove and the contact wheel and stably extruding the lubricating oil. The snap-fitting installation of the displacement lever and the connecting groove and the installation of rotating balls at the connecting end ensure that the electric push rod can accurately drive the movement of the functional sleeve on the one hand, and reduce the frictional resistance between the two on the other hand, making the displacement adjustment of the functional sleeve more sensitive and efficient.

[0007] Preferably, the extrusion groove is an arc design with different depths at both ends. The mounting barrel and the extrusion rod are in sliding friction connection, and a spring is connected between the mounting barrel and the extrusion rod. The outer surface of the contact wheel is attached to the outer surface of the functional sleeve.

[0008] With the above technical solution, the arc design with different depths at both ends of the extrusion groove, combined with the rotation of the functional sleeve, can make the contact wheel drive the extrusion rod to generate displacements of different degrees, thereby flexibly controlling the pressure change in the mounting barrel and accurately adjusting the extrusion amount of the lubricating oil. The sliding friction connection between the mounting barrel and the extrusion rod and the spring between the two can not only ensure the smooth sliding of the extrusion rod under the action of pressure, but also enable the extrusion rod to reset in time when the pressure disappears, ensuring the stable and continuous extrusion process of the lubricating oil. The attachment of the contact wheel to the outer surface of the functional sleeve can effectively transmit the rotational power of the functional sleeve, ensuring the efficient action between the extrusion groove and the contact wheel and stably extruding the lubricating oil.

[0009] Preferably, both the first sedimentation pipe and the second sedimentation pipe are inclined downward away from the liquid outlet check valve. The tubular lower end of the liquid outlet check valve penetrates the lower surface of the overflow box. A gap is left between the lower ends of the first sedimentation pipe and the second sedimentation pipe and the inner bottom surface of the overflow box.

[0010] With the above technical solution, the first sedimentation tube and the second sedimentation tube are inclined. By using the gravitational force, the impurities in the lubricating oil are more likely to precipitate to the bottom of the tube during the flowing process. The tubular lower end of the liquid outlet one-way valve penetrates through the lower surface of the overflow box, preventing the impurities deposited in the overflow box from flowing out with the lubricating oil. The gap left between the lower end of the sedimentation tube and the bottom of the overflow box not only ensures that the precipitated impurities can smoothly deposit to the bottom of the overflow box, but also does not hinder the normal circulating flow of the purified lubricating oil in the overflow box, effectively realizing the separation and collection of the impurities in the lubricating oil.

[0011] Preferably, the injection port is designed as a hollow frustum shape with a smaller upper part and a larger lower part. The first baffle plate is designed as a V shape with an open bottom, and the two ends of the first baffle plate are respectively opposite to the upper openings of the second sedimentation tubes on both sides. And there is a gap between the two ends of the first baffle plate and the connection parts of the lower end of the liquid outlet one-way valve and the upper opening of the first sedimentation tube. Both the first flow baffle plate and the second baffle plate are obliquely arranged with the lower ends facing the first sedimentation tube, and there is a gap between the upper end of the first flow baffle plate and the inner surface of the lower end of the liquid outlet one-way valve. There is a gap between the lower end of the second baffle plate and the inner surface of the upper end of the first sedimentation tube.

[0012] With the above technical solution, the design of the injection port with a smaller upper part and a larger lower part can accelerate the flow rate when the lubricating oil flows out, enhance the scouring force on the impurities, making them easier to separate. The V-shaped design and the position layout of the first baffle plate can guide the impurities to flow towards the second sedimentation tubes on both sides, while preventing the impurities from directly entering the injection pipe. The oblique arrangement and the gap design of the first flow baffle plate and the second baffle plate further change the flow paths of the lubricating oil and the impurities, enabling the impurities to fully precipitate into the first sedimentation tube under the action of gravity and fluid, effectively improving the impurity separation effect and ensuring the cleanliness of the lubricating oil entering the circulation.

[0013] Preferably, a spring is connected between the sliding cylinder and the contact plate, and the contact plate is arc-shaped and is equally angularly distributed on the outer surface of the functional sleeve. Both ends of the guide groove are designed with arc-shaped chamfers.

[0014] With the above technical solution, the spring between the sliding cylinder and the contact plate can provide a restoring force after the contact plate is displaced by the centrifugal force, ensuring that the contact plate can flexibly respond to the change in the inner ring rotation speed. The arc-shaped design and the equal angular distribution of the contact plate enable it to be evenly affected by the centrifugal force when the functional sleeve rotates, ensuring stable and balanced pushing on the guide rod. The arc-shaped chamfer design at both ends of the guide groove reduces the collision and wear when the guide rod engages with the guide groove, making the sliding of the guide rod in the guide groove smoother and improving the response speed and stability of the follow-up adjustment mechanism.

[0015] Preferably, a spring is connected between the mounting cylinder and the guide rod, and the end of the guide rod located inside the mounting cylinder is directly opposite to the proximity sensor.

[0016] With the above technical solution, the spring between the mounting cylinder and the guide rod plays a buffering and resetting role, avoiding the impact on the proximity sensor caused by excessive instantaneous displacement of the guide rod. At the same time, it enables the guide rod to quickly return to the initial position when no external force is applied or the external force disappears, ensuring the accuracy and stability of the proximity sensor detection. One end of the guide rod faces the proximity sensor, enabling the proximity sensor to accurately sense the position change of the guide rod and timely transmit the signal to the control system, providing a reliable basis for precisely adjusting the electric push rod and ensuring the precise and timely adjustment of the lubricating oil output.

[0017] Preferably, one end of the guide rod facing the contact plate is designed in an L shape, and the guide rod is snap-fitted with the guide groove through the L-shaped end.

[0018] With the above technical solution, the L-shaped design of the guide rod enables it to be stably snap-fitted with the guide groove. When the contact plate displaces, it effectively converts the radial movement of the contact plate into the axial movement of the guide rod, ensuring that the guide rod accurately transmits the displacement signal of the contact plate. This snap-fitting installation method enhances the stability of the connection between the components of the follow-up adjustment mechanism, ensuring that the follow-up adjustment mechanism can still operate reliably under high-speed operation and complex working conditions, precisely adjusting the lubricating oil output, and adapting to different working conditions.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the high-stability energy-saving and noise-reducing bearing seat: 1. When the inner ring rotates, it drives the functional sleeve. The extrusion groove on the outer side of the functional sleeve cooperates with the contact wheel and the extrusion rod, enabling automatic extrusion and lubrication of the lubricating oil without frequent manual oil injection. The lubricating oil is recovered through the oil collecting grooves at both ends of the base and is circulated after being statically purified through the overflow box, the first sedimentation pipe, and the second sedimentation pipe in the liquid storage box, reducing the consumption of lubricating oil and the operating cost, meeting the requirements of energy conservation and consumption reduction; 2. When the rotation speed of the inner ring changes, the contact plate at one end of the functional sleeve displaces under the action of centrifugal force. The guide groove of the contact plate cooperates with the guide rod, enabling the proximity sensor in the mounting cylinder to sense the signal change, and then controlling the electric push rod to adjust the position of the functional sleeve, realizing the adaptive adjustment of the lubricating oil output, and ensuring that the bearing can obtain a suitable lubrication effect under different working conditions; 3. Through the self-lubricating mechanism and the follow-up adjustment mechanism, continuous and precise lubrication is achieved, reducing the friction during the rotation of the inner ring, effectively reducing high-frequency vibration and noise, and improving the working environment. At the same time, stable lubrication ensures the smooth operation of the bearing, reduces the problem of loosening of equipment components caused by vibration, improves the operation stability of the equipment. Meanwhile, in the liquid storage box, the inclined settings of the first sedimentation pipe and the second sedimentation pipe, combined with structures such as the injection port, the first baffle plate, the first flow baffle plate, and the second baffle plate, achieve efficient separation of impurities in the recycled lubricating oil, causing the impurities to precipitate to the bottom of the overflow box, ensuring the cleanliness of the lubricating oil entering the circulation, effectively reducing the wear of the bearing by impurities, extending the service life of the bearing, and improving the overall reliability of the equipment.

An air inlet groove 17 is provided between the upper end of the air inlet pipe 16 and the inner bottom surface of the installation barrel 11. An overflow box 18 is fixedly arranged inside the liquid storage box 14. A liquid outlet check valve 19 is fixedly installed at the upper end of the liquid storage box 14. The lower end of the liquid outlet check valve 19 is designed in a tubular shape. A first precipitation pipe 20 and a second precipitation pipe 21 are fixedly arranged on the outer surface of the tubular lower end of the liquid outlet check valve 19. A liquid injection port 22 is fixedly arranged inside the tubular lower end of the liquid outlet check valve 19. A first baffle plate 23 is fixedly arranged on the inner surface of the lower end of the liquid outlet check valve 19 above the liquid injection port 22. A first flow baffle 24 and a second baffle plate 25 are fixedly arranged at the connection between the lower end of the liquid outlet check valve 19 and the upper end of the first precipitation pipe 20. A liquid injection pipe 27 is connected between the liquid injection port 26 and the liquid outlet check valve 19. A liquid inlet check valve 15 is fixedly installed on the lower side surface of the liquid storage box 14. One end of the liquid inlet check valve 15 is fixedly connected to one end of a liquid suction pipe 28, and the other end of the liquid suction pipe 28 penetrates through the filter screen 5 and is located inside the oil collecting groove 4; The lower ends of the 2 oil collecting grooves 4 communicate with each other. The functional sleeve 6 is concentrically arranged with the inner ring 3. One end of the displacement lever 9 is snap-fitted with the connection groove 7, and a rotating ball is installed on the outer surface of the end of the displacement lever 9 connected to the connection groove 7; The extrusion groove 10 is designed as an arc with different groove depths at both ends. The installation barrel 11 and the extrusion rod 12 are in sliding friction connection, and a spring is connected between the installation barrel 11 and the extrusion rod 12. The outer surface of the contact wheel 13 is attached to the outer surface of the functional sleeve 6; Both the first precipitation pipe 20 and the second precipitation pipe 21 are inclined with the lower ends away from the liquid outlet check valve 19. The tubular lower end of the liquid outlet check valve 19 penetrates through the lower surface of the overflow box 18. A gap is left between the lower ends of the first precipitation pipe 20 and the second precipitation pipe 21 and the inner bottom surface of the overflow box 18; The liquid injection port 22 is designed as a hollow frustum shape with a smaller upper part and a larger lower part. The first baffle plate 23 is designed as a V shape with the opening facing downwards. The two ends of the first baffle plate 23 are respectively opposite to the upper ends of the second precipitation pipes 21 on both sides. A gap is left between the two ends of the first baffle plate 23 and the connections between the lower end of the liquid outlet check valve 19 and the upper ends of the first precipitation pipes 20. Both the first flow baffle 24 and the second baffle plate 25 are inclined with the lower ends facing the first precipitation pipe 20. A gap is left between the upper end of the first flow baffle 24 and the inner surface of the lower end of the liquid outlet check valve 19. A gap is left between the lower end of the second baffle plate 25 and the inner surface of the upper end of the first precipitation pipe 20; When the inner ring 3 rotates, it drives the function sleeve 6 slidably installed thereon to rotate together. During the rotation of the function sleeve 6, the extrusion groove 10 on the outer side of the function sleeve 6 will interact with the contact wheel 13. As the function sleeve 6 rotates, the contact wheel 13 will alternately contact between the extrusion groove 10 and the outer surface of the function sleeve 6, and then cooperate with the spring to push the extrusion rod 12 to reciprocate in the installation barrel 11. This movement of the extrusion rod 12 causes the pressure in the installation barrel 11 to change. Through the air inlet pipe 16 and the air inlet groove 17, it prompts the lubricating oil in the liquid storage box 14 to flow out through the liquid outlet one-way valve 19. When the lubricating oil flows out of the liquid outlet one-way valve 19, it passes through the injection port 22. Due to the design of the injection port 22 with a smaller upper part and a larger lower part, there will be a certain change in the flow rate. At the same time, the special structures of the first baffle plate 23, the first flow baffle plate 24 and the second baffle plate 25 cause the impurities in the lubricating oil to move and precipitate towards the first sedimentation pipe 20 and the second sedimentation pipe 21 respectively under the action of gravity and hydrodynamics. The lubricating oil that has been preliminarily filtered then continues to enter the gland 2 through the injection pipe 27 and the injection port 26 to lubricate the bearing. During the operation of the bearing seat, the used lubricating oil will flow into the oil collecting grooves 4 at both ends of the base 1. The filter screen 5 at the upper end of the oil collecting groove 4 will conduct a primary filtration on the lubricating oil to intercept larger particle impurities. After that, the lubricating oil is sucked back into the liquid storage box 14 through the liquid suction pipe 28 and the liquid inlet one-way valve 15. After standing and removing impurities in the overflow box 18, the first sedimentation pipe 20 and the second sedimentation pipe 21 in the liquid storage box 14, it realizes cyclic use.

[0025] Embodiment 2: This embodiment discloses on the basis of Embodiment 1 that a follow-up adjustment mechanism is provided on the outer surfaces of the function sleeve 6 and the electric push rod 8 for adaptively adjusting the output amount of the lubricating oil by real-time monitoring of the rotation speed of the inner ring 3; The follow-up adjustment mechanism includes: a sliding cylinder 29, which is fixedly arranged on the outer surface of one end of the function sleeve 6. A sliding contact plate 30 is installed at one end of the function sleeve 6, and a guiding groove 31 is opened on the outer surface of the contact plate 30. A sliding installation cylinder 32 is installed on the outer surface of the electric push rod 8, and a sliding guiding rod 33 is installed inside one end of the installation cylinder 32, and a proximity sensor 34 is fixedly installed inside the installation cylinder 32; A spring is connected between the sliding cylinder 29 and the contact plate 30, and the contact plate 30 is arc-shaped, and the contact plate 30 is equally angularly distributed on the outer surface of the function sleeve 6. Both ends of the guiding groove 31 are arc-shaped chamfered designs; A spring is connected between the installation cylinder 32 and the guiding rod 33, and the end of the guiding rod 33 located inside the installation cylinder 32 is directly opposite to the proximity sensor 34; The end of the guiding rod 33 facing the contact plate 30 is L-shaped, and the guiding rod 33 is snap-fitted with the guiding groove 31 through the L-shaped end; When the rotational speed of the inner ring 3 changes, the contact plate 30 at one end of the functional sleeve 6 will displace due to the change in centrifugal force. Since the contact plate 30 is arc-shaped and evenly distributed on the outer surface of the functional sleeve 6, and there is a spring connected between it and the sliding cylinder 29, when the centrifugal force changes, the contact plate 30 will slide along the radial direction of the functional sleeve 6 under the action of the spring. The guiding groove 31 on the outer side of the contact plate 30 engages with the L-shaped end of the guiding rod 33, and the guiding rod 33 slides within the mounting cylinder 32. The spring connected between the mounting cylinder 32 and the guiding rod 33 plays a buffering and resetting role. When the guiding rod 33 moves with the displacement of the contact plate 30, the proximity sensor 34 within the mounting cylinder 32 will sense the change in the position of the guiding rod 33, thereby generating an electrical signal. This electrical signal will be transmitted to the control system of the electric push rod 8, and the control system controls the operation of the electric push rod 8 according to the signal change. The electric push rod 8 adjusts the position of the functional sleeve 6 through the displacement lever 9 and the connecting groove 7, so that the relative position between the extrusion groove 10 and the contact wheel 13 changes, and the extrusion amount of the lubricating oil is adjusted by means of the different depths at both ends of the extrusion groove 10. When the rotational speed of the inner ring 3 increases, the centrifugal force of the contact plate 30 increases, and the guiding rod 33 moves towards the direction closer to the proximity sensor 34. The proximity sensor 34 sends a signal, and the electric push rod 8 pushes the functional sleeve 6, making the end with a deeper depth of the extrusion groove 10 closer to the contact wheel 13, increasing the extrusion amount of the lubricating oil. On the contrary, when the rotational speed of the inner ring 3 decreases, the electric push rod 8 pulls the functional sleeve 6, reducing the extrusion amount of the lubricating oil, thereby realizing the adaptive adjustment of the output amount of the lubricating oil and ensuring that the bearing can obtain a suitable lubrication effect under different working conditions.

[0026] In the above specific embodiments, the purpose, technical solutions, and beneficial effects of the present invention have been further described in detail. It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included within the protection scope of the present invention.
