Description

Technical Field

[0001] This utility model relates to the field of bearing friction control technology, and in particular to a sliding bearing friction control device based on surface texture. Background Technology

[0002] The friction control device for sliding bearings based on surface texture changes the fluid lubrication state and contact characteristics between contact surfaces by processing micro or macro textures of specific shapes, sizes and distributions on the bearing surface. The texture can optimize the distribution of lubricating oil and form local high-pressure areas, thereby controlling the friction coefficient and reducing wear. This device does not require a complex internal structure and improves friction performance through surface texture design. It has the potential to improve the reliability and efficiency of bearings in mechanical engineering, aerospace and other fields.

[0003] The friction control device for sliding bearings based on surface texture utilizes the texture of the bearing surface to change the lubrication state. During movement, the texture can capture lubricating oil to form "micro-oil pools," creating a hydrodynamic pressure effect between the contact surfaces, increasing the oil film thickness and load-bearing capacity. Simultaneously, the texture induces eddies in the fluid, enhancing the wedging effect of the lubricating oil and reducing direct metal-to-metal contact. By optimizing the shape and distribution of the texture, the interfacial friction state can be controlled, transitioning from boundary lubrication to mixed or all-fluid lubrication, reducing the coefficient of friction and wear, and achieving efficient friction control.

[0004] In existing technologies, some sliding bearing friction control devices require manual lubrication at regular intervals, which can easily lead to insufficient or excessive lubrication. When lubrication is insufficient, the bearing friction surfaces come into direct contact, which intensifies wear, causes a sudden rise in temperature, shortens the bearing life, and may even cause equipment failure and shutdown. Excessive lubrication, on the other hand, will waste lubricating oil and will also pollute the working environment and increase energy consumption due to oil splashing. Therefore, a sliding bearing friction control device based on surface texture is proposed to solve the above problems. Utility Model Content

The right side of the rack is meshed with the outer side of the gear. An oil support plate is fixedly connected to the top end of the rack.

[0011] The drive end of the motor is rotatably connected inside the support plate, the left side of the triangular ring is in contact with the right side of the sliding rod, and the inner side of the bearing bush is slidably connected to the journal.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the operator starts the motor, the drive end drives the triangular ring to make a circular motion, which pushes the connecting rod and the contact rod to make the sliding rod reciprocate within the fixed block. The sliding block reciprocates with the connecting rod. When it moves backward, the lubricating oil flows from the external oil pipe through the internal groove of the sliding block into the connecting pipe and finally reaches the bearing bush. When it moves forward, the sliding block blocks the outlet to stop the oil supply, thus realizing the automated quantitative supply of bearing lubricating oil. This avoids the problem of excessive or insufficient manual lubrication, preventing waste and pollution, and ensuring that the bearing is in the best lubrication condition.

[0024] 2. In this utility model, the operator starts the electric push rod, which drives the rack one to move. Through the transmission of gear one and gear two, the rack two slides in the fixed ring, thereby controlling the raising and lowering of the oil support plate. When it is necessary to increase the friction, the oil support plate lowers to reduce the amount of lubricating oil. When it is necessary to run smoothly, the oil support plate rises to increase the amount of oil. This device can automatically adjust the amount of lubrication according to the working conditions, maintain the best lubrication state, reduce the risk of failure, extend the bearing life, reduce maintenance downtime, and improve operating efficiency.

[0034] 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 protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 3 , Figure 5This utility model provides an embodiment of a sliding bearing friction control device based on surface texture, comprising an upper bearing seat 1. The upper bearing seat 1 and lower bearing seat 15 serve as the basic framework of the entire device, playing a crucial role in supporting and fixing other components, and providing a stable installation and operation platform for the entire device. A motor 2 is fixedly connected inside the upper bearing seat 1. The motor 2 is the power core of the device, outputting power through its drive end to provide a power source for the movement of subsequent components. A triangular ring 3 is fixedly connected to the drive end of the motor 2, rotating under the drive of the motor 2. The unique shape design of the triangular ring 3 allows it to drive subsequent components to produce regular displacement changes during rotation, serving as the starting power for a series of subsequent movements. A support plate 8 is fixedly connected inside the upper bearing seat 1, providing an installation base for a fixed block 7 and ensuring the stable position of the fixed block 7 within the device.

[0036] Two fixed blocks 7 are fixedly connected to the right side of the support plate 8. The two fixed blocks 7 have sliding channels inside, providing a sliding track for the sliding rod 6, allowing the sliding rod 6 to slide linearly left and right within them. The sliding rod 6 is slidably connected inside the two fixed blocks 7. A contact rod 5 and a connecting rod 4 are fixedly connected to the right side of the sliding rod 6. The sliding rod 6 rotates, causing the contact rod 5 and connecting rod 4 to move back and forth. A sliding block 9 is fixedly connected to the other end of the connecting rod 4. The connecting rod 4 further transmits the movement of the sliding rod 6 to the sliding block 9, causing the sliding block 9 to reciprocate along with the connecting rod 4. A fixed seat 10 is slidably connected to the outside of the sliding block 9. The sliding block 9 slides inside the fixed seat 10, which provides guidance and limitation for the sliding block 9, ensuring that the sliding block 9 slides along a predetermined trajectory.

[0037] An external oil pipe 11 is fixedly connected to the top of the fixed base 10. This external oil pipe 11 is fixed to the top of the fixed base 10 and is used to connect to an external oil supply device to introduce lubricating oil into the device. A connecting pipe 12 is fixedly connected to the bottom of the fixed base 10. The connecting pipe 12 is connected to the bearing bush 13. After the lubricating oil enters the fixed base 10 through the external oil pipe 11, it is then transported to the bearing bush 13 through the connecting pipe 12, providing lubrication for the friction surface between the bearing bush 13 and the journal 27. The bearing bush 13 is installed at the bottom of the upper bearing housing 1. The bearing bush 13 is a key component that directly contacts and generates friction with the journal 27. The lubricating oil forms a lubricating film on the surface of the journal 27, which can effectively reduce the coefficient of friction between the journal 27 and the bearing bush 13, reducing wear. An adjustment component for adjusting the oil quantity is provided at the bottom of the upper bearing housing 1.

[0038] Reference Figure 1 , Figure 6 , Figure 7The adjusting assembly includes two screws 14, the outer threads of which are connected to the interior of the upper bearing housing 1, and the outer threads of which are connected to the lower bearing housing 15. The screws 14 serve as a connection and support, connecting the upper bearing housing 1 and the lower bearing housing 15. The lower bearing housing 15 provides a stable mounting platform for the electric push rod 16, ensuring that the electric push rod 16 can operate stably and output power. The bearing bush 13 inside is fixed, and the electric push rod 16 is fixedly connected inside the lower bearing housing 15. The electric push rod 16 converts the rotational motion of the motor 2 into the linear reciprocating motion of the drive end, providing stable power for subsequent components. The drive end of the electric push rod 16 is fixedly connected to a rack 17, and a fixing plate 18 is slidably connected to the outer side of the rack 17. Under the push of the electric push rod 16, the rack 17 can slide linearly along the fixing plate 18.

[0039] The fixed plate 18 provides a stable sliding track for the rack 17, restricting its direction of movement and ensuring that the rack 17 does not deviate during sliding, thus ensuring the accuracy of power transmission. A connecting plate 22 is fixedly connected inside the lower bearing housing 15, providing a rotation fulcrum for the rotating shaft 21. The rotating shaft 21 passes through the connecting plate 22 and can rotate freely within it. The rotating shaft 21 is rotatably connected inside the connecting plate 22. A gear 20 is fixedly connected to the front side of the rotating shaft 21. The outer side of the gear 20 is meshed with the top of the rack 17. When the electric push rod 16 pushes the rack 17 to slide linearly, the rack 17, through meshing with the gear 20, drives the gear 20 to rotate around the rotating shaft 21. Since the gear 20 is fixedly connected to the rotating shaft 21, the rotation of the gear 20 will drive the rotating shaft 21 to rotate synchronously.

[0040] A gear 23 is fixedly connected to the other end of the rotating shaft 21, and the gear 23 rotates as the rotating shaft 21 rotates. A fixed ring 25 is fixedly connected inside the lower bearing housing 15, and a rack 24 is slidably connected inside the fixed ring 25. The right side of the rack 24 meshes with the outer side of the gear 23, and its interior provides a sliding channel for the rack 24. When the gear 23 rotates, it drives the rack 24 to slide linearly within the fixed ring 25 through meshing transmission. An oil support plate 26 is fixedly connected to the top of the rack 24, and the oil support plate 26 moves up and down as the rack 24 slides.

[0041] Reference Figure 2 , Figure 4 , Figure 7The drive end of motor 2 is rotatably connected inside the support plate 8. This connection method ensures the stable installation of motor 2 and allows the drive end to rotate flexibly, stably outputting the rotational power generated by motor 2. The left side of the triangular ring 3 contacts the right side of the sliding rod 6. The inner side of the bearing bush 13 is slidably connected to the journal 27. When the journal 27 rotates inside the bearing bush 13, friction is generated. The lubricating oil forming a lubricating film between the two can effectively reduce the coefficient of friction and reduce wear. A sliding groove is provided on the left side of the fixed seat 10. The outer side of the connecting rod 4 is slidably connected inside the sliding groove. The connecting rod 4 transmits the movement of the sliding rod 6 to the sliding block 9. The sliding groove on the left side of the fixed seat 10 provides a sliding track for the connecting rod 4, allowing the connecting rod 4 to slide only in the left and right directions within the sliding groove. The outer side of the external oil pipe 11 is fixedly connected to the inside of the upper bearing seat 1, and the outer side of the connecting pipe 12 is fixedly connected to the inside of the upper bearing seat 1. When the sliding block 9 slides in the fixed seat 10, it can achieve preliminary adjustment of the lubricating oil flow rate by changing the flow area between the external oil pipe 11 and the connecting pipe 12. The external oil pipe 11 is responsible for introducing external lubricating oil, while the connecting pipe 12 delivers the lubricating oil to the bearing bush 13. The movement of the sliding block 9 can adjust the degree of conduction between the two, thereby controlling the amount of lubricating oil entering the bearing bush 13.

[0042] The rear side of the fixed seat 10 is fixedly connected to the interior of the upper bearing seat 1. A support 19 is slidably connected to the bottom end of rack 17, and the bottom end of support 19 is fixedly connected to the interior of the lower bearing seat 15. The bottom end of the fixed plate 18 is also fixedly connected to the interior of the lower bearing seat 15. The fixed plate 18 and support 19, fixedly connected to the interior of the lower bearing seat 15, provide horizontal support and guidance for rack 17, ensuring the stability and accuracy of its linear movement. A groove is provided inside the lower bearing seat 15, and the outer side of the oil support plate 26 is slidably connected to the interior of the groove. The outer side of rack 24 is slidably connected to the interior of the upper bearing seat 1, and the outer side of the oil support plate 26 is slidably connected to the interior of the bearing bush 13. When the oil support plate 26 moves upward, it can deliver excess lubricating oil to the friction surface between the bearing bush 13 and the journal 27, increasing lubrication; when the oil support plate 26 moves downward, it temporarily stores the unnecessary lubricating oil.

[0043] Working principle: The operator starts motor 2, which drives the triangular ring 3 fixedly connected to its drive end to perform circular motion. During the circular motion, the triangular ring 3 contacts the connecting rod 4 and the contact rod 5, pushing the connecting rod 4 and the contact rod 5 to drive the sliding rod 6 to reciprocate inside the fixed block 7. While the connecting rod 4 is reciprocating, it also drives the sliding block 9 to reciprocate inside the fixed seat 10. When the sliding block 9 moves backward, the lubricating oil in the external oil pipe 11 flows from the groove inside the sliding block 9 to the connecting pipe 12, and then from the connecting pipe 12 to the space between the bearing bush 13 and the journal 27. When the sliding block 9 moves forward, the front of the sliding block 9 blocks the outlet connecting the fixed seat 10 and the external oil pipe 11, realizing automated quantitative lubrication of the bearing. This avoids the problem of excessive or insufficient oil due to insufficient experience in manual lubrication. It can prevent waste and pollution caused by excessive oil, and also prevent bearing wear, overheating or even failure caused by insufficient oil, ensuring that the bearing is in the best lubrication condition.

[0044] The operator activates the electric push rod 16, which in turn moves rack 17, causing gear 20 to rotate. This converts the linear motion of rack 17 into circular motion of gear 20, which in turn drives gear 23 to rotate. Gear 23 then transmits the motion to rack 24, causing rack 24 to slide inside the fixed ring 25. This, in turn, causes the oil support plate 26 to slide. When it is necessary to increase the internal friction of the bearing during operation, the electric push rod 16 is activated to lower the oil support plate 26, reducing the amount of oil between journal 27 and bearing shell 13. If smoother bearing operation is required, the electric push rod 16 is used to raise the subsequent components, allowing the lubricating oil to return to the space between journal 27 and bearing shell 13. This achieves the effect of controlling the amount of oil according to the working conditions, maintaining good lubrication, effectively reducing the risk of equipment failure, extending the service life of sliding bearings, reducing maintenance frequency and downtime, and improving equipment operating efficiency.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
