Description

Technical Field

[0001] This invention relates to the field of water-lubricated bearing technology, specifically to intelligent water-lubricated dynamic adjustable bearings and bearing support control methods. Background Technology

[0002] With the promotion of green, environmentally friendly, and energy-efficient technologies, water-lubricated bearings are increasingly being used in the propulsion shafting of large ships to replace traditional oil lubrication. Water-lubricated bearings typically rely on the rotation of the journal to form a dynamic water film, achieving support and lubrication for the shaft. However, in actual operation, this type of bearing still has the following prominent defects and problems: 1. The shafting structure is relatively long, making it prone to shaft misalignment and uneven wear. The propulsion shafting axis of large ships is usually long. Under load, hull deformation, or center of gravity shift, the shafting as a whole may experience a certain degree of radial deflection or shaft misalignment. This makes it impossible for the originally aligned bearings to adapt to the shaft center change in real time, resulting in a certain area of ​​the bearing bearing bearing excessive load for a long time, forming asymmetrical wear or "uneven wear".

[0003] 2. Rigid bearings lack adaptability to load changes. Traditional water-lubricated bearings are mostly rigid structures with fixed slats. Their support stiffness is not adjustable during operation, making them unable to actively respond to load changes or shaft displacement. Especially under large load disturbances (such as heavy loads, steering, mooring, etc.), the distribution of support force is difficult to adjust, easily leading to localized impact stress concentration.

[0004] 3. Lack of real-time sensing and control mechanisms. Existing water-lubricated bearings generally lack sensors or feedback devices, making it impossible to obtain real-time data on load distribution, support deformation, or shaft center position within the bearing. The entire system operates in a "black box" state. Problems caused by this often can only be passively discovered through periodic downtime maintenance, making it impossible to proactively predict or intervene in the bearing wear process.

[0005] In summary, existing water-lubricated bearings have significant shortcomings in terms of structural rigidity, adaptability, and intelligence, making it difficult to meet the next-generation operational requirements of large ship propulsion shafting systems for "high reliability, long lifespan, and self-adaptability." Therefore, there is an urgent need to develop a water-lubricated bearing structure capable of dynamic adjustment, intelligent sensing, and autonomous response to effectively improve system stability and lifespan. Summary of the Invention

[0006] To address the aforementioned shortcomings of existing technologies, an intelligent water-lubricated dynamically adjustable bearing and bearing support control method are provided, which realizes dynamic adjustment of bearing support force and can effectively suppress uneven wear and improve water film stability.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: Firstly, intelligent water-lubricated dynamically adjustable bearings are used for supporting large propulsion shaft systems; including... The bearing housing has a cylindrical cavity inside, and a large propulsion shaft system is placed inside the cylindrical cavity; several first mounting grooves are provided at intervals along the circumferential direction and axial direction inside the bearing housing. A number of slats are laid on the surface of the cylindrical cavity of the bearing housing, and a second mounting groove matching the first mounting groove is provided on the slats. The first mounting groove and the second mounting groove form an arc-shaped cavity. The slats are located between the inner wall of the cylindrical cavity and the outer wall of the large propulsion shaft system, and a water film lubrication layer is formed between the slats and the outer wall of the large propulsion shaft system. The adjustment module is provided in each arc-shaped cavity; the adjustment module is provided with a sealed cavity, and the side of the sealed cavity facing the strip is a flexible sealing diaphragm, which bulges out or retracts along the radial direction of the cylindrical cavity; The system includes a hydraulic system, a control system, and a sensor module. Each sealed cavity is equipped with a sensor module. The hydraulic system is connected to each sealed cavity, and the control system is connected to both the hydraulic system and each sensor module. Based on the data from the sensor modules, the system independently controls the inflow or depressurization of each sealed cavity, thereby causing the sealed cavity to bulge out or retract, thus adjusting the local height of the slats.

[0008] According to the above technical solution, the adjustment module has an arc-shaped structure and matches the arc-shaped cavity; the adjustment module includes a module housing and a flexible sealing diaphragm, the module housing is provided with a sealing groove, the flexible sealing diaphragm is fixed on the side wall of the sealing groove, and the flexible sealing diaphragm and the sealing groove constitute the sealing cavity; the sensor module is installed at the bottom of the sealing cavity.

[0009] According to the above technical solution, the module housing of a single adjustment module is provided with two sealing grooves, and a matching flexible sealing diaphragm is fixedly installed in each sealing groove; a support part is provided between the two sealing grooves, and the support part and the module housing are integrally set; a connecting hole for connecting the two sealing grooves is provided on the support part, and a plate strip is supported by the support part.

[0010] According to the above technical solution, the flexible sealing diaphragm is made of a highly elastic and corrosion-resistant material. It undergoes slight deformation in response to the pressure of the sealing cavity and pushes the slats to produce changes in support height.

[0011] According to the above technical solution, the sensor module includes a load sensor, a pressure sensor, and a displacement sensor.

[0012] According to the above technical solution, the hydraulic system includes a main circuit and several branches connected in parallel to the main circuit. A hydraulic pump is provided on the main circuit, and a valve group is provided on each branch. Each branch is connected to the sealed cavity of an adjustment module.

[0013] According to the above technical solution, the control system is an integrated control unit, including a signal acquisition module, a control logic module, and an instruction execution module.

[0014] According to the above technical solution, the bearing housing is composed of an upper housing and a lower housing, which are connected by bolts. The connected bearing housing is an integral cylindrical structure, and the cylindrical cavity is located inside the cylindrical structure.

[0015] According to the above technical solution, the first mounting groove is provided at equal intervals along the circumferential direction and along the axial direction of the cylindrical cavity on the inner wall of the cylindrical cavity of the bearing housing.

[0016] Secondly, a bearing support control method, applied to any of the intelligent water-lubricated dynamically adjustable bearings shown above, the method comprising: The control system collects load, pressure, and displacement information of each adjustment module in real time; If the load on a certain area adjustment module increases abnormally, the control system adjusts the liquid pressure in the sealed cavity of the adjustment module through the hydraulic system, causing the flexible sealing diaphragm to decrease slightly, reducing the local support stiffness, while increasing the load to reduce the liquid pressure in the sealed cavity of the adjustment module; thus maintaining the liquid pressure in the adjustment module within the set range. If the pressure in the sealed cavity exceeds the limit or the operation is abnormal, the pressure relief channel will intervene in time to ensure structural safety; during operation, continuous adjustment will be made to ensure that the flexible sealing diaphragm is stable, wears evenly, and the off-center load is reduced; When the liquid pressure in the regulating module is within a suitable range, if a tendency for uneven wear or shaft misalignment is detected, the system coordinates the liquid pressure in multiple regulating modules to achieve shaft adjustment.

[0017] The present invention has the following beneficial effects: Multiple adjustment modules are evenly arranged circumferentially and axially between the bearing housing and the slats to support the slats and adjust their local support height. Each adjustment module contains a corresponding sensor module, and a hydraulic and control system is connected to each module and its corresponding sensor module, thus constructing an intelligent support system with self-sensing and active adjustment capabilities.

[0018] Based on this intelligent water-lubricated dynamic adjustment bearing: First, it enables dynamic adjustment of bearing support force. By setting a hydraulic adjustment module with variable thickness between the slats and the bearing housing, and in conjunction with a closed-loop control system, it can dynamically adjust the local support force according to the load distribution, thereby achieving active support adjustment function.

[0019] Secondly, it effectively alleviates the problem of uneven bearing wear. Multiple adjustment modules are arranged circumferentially, and through coordinated control, they can compensate for the uneven load caused by journal eccentricity or shaft deflection, thereby effectively reducing the risk of uneven bearing wear and improving service life.

[0020] Third, it enhances the water film establishment capability and lubrication stability. Under conditions such as low speed and heavy load that are prone to instability, the adjustment module can appropriately increase the support height or rigidity to help establish a stable water film lubrication layer and reduce start-up wear and dry friction.

[0021] Fourth, the modular design facilitates installation and maintenance. The adjustment module is located between the slats and the housing, with an independent structure that can be replaced in units. It is easy to install and modify, and is suitable for new bearing systems or intelligent upgrades of existing structures.

[0022] Fifth, it integrates sensing functions to improve the intelligence level of the equipment. The sensors integrated inside the adjustment module can monitor the operating status such as load and pressure, forming a closed loop of sensing-control-execution, and has self-adaptive and self-diagnostic capabilities.

[0023] In summary, this invention achieves dynamic adjustment of bearing support force by setting several independently controlled adjustment modules between the bearing housing and the slats, combined with the control feedback of the hydraulic system, control system and sensor module. It can effectively suppress uneven wear and improve water film stability. It is particularly suitable for long shaft system structures such as large ships, and has the advantages of reasonable structure, flexible response and convenient installation.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1 Reference Figures 1-2 As shown, the present invention provides an intelligent water-lubricated dynamic adjustment bearing.

[0031] Supports used in large propulsion shaft systems; including The bearing housing 1 has a cylindrical cavity inside, and a large propulsion shaft system is placed inside the cylindrical cavity; several first mounting grooves are provided at intervals along the circumferential direction and axial direction inside the bearing housing. Slat 2, several slats are laid on the surface of the cylindrical cavity of the bearing housing, and a second mounting groove matching the first mounting groove is provided on the slat. The first mounting groove and the second mounting groove form an arc-shaped cavity. The slat is located between the inner wall of the cylindrical cavity and the outer wall of the large propulsion shaft system, and a water film lubrication layer is formed between the slat and the outer wall of the large propulsion shaft system. Adjustment module 3, each arc-shaped cavity is provided with an adjustment module; the adjustment module is provided with a sealing cavity 3-1, and the side of the sealing cavity facing the strip is a flexible sealing diaphragm 3-2, which bulges out or retracts along the radial direction of the cylindrical cavity; The system comprises a hydraulic system 4, a control system 5, and a sensor module 6. Each sealed cavity is equipped with a sensor module. The hydraulic system is connected to each sealed cavity, and the control system is connected to both the hydraulic system and each sensor module. Based on the data from the sensor modules, the system independently controls the inflow or depressurization of each sealed cavity, thereby causing the sealed cavity to bulge out or retract, thus adjusting the local height of the slats.

[0032] A flexible sealing diaphragm, made of highly elastic and corrosion-resistant material, is positioned above the sealed cavity. It undergoes slight deformation in response to cavity pressure, causing changes in the support height of the slats. By altering the pressure within the sealed cavity, the flexible sealing diaphragm can be bulged out or retracted into the cavity, thus adjusting the thickness of the adjustment module.

[0033] The intelligent water-lubricated dynamic adjustable bearing of this invention utilizes multiple adjusting modules evenly arranged circumferentially and axially between the bearing housing and the slats to support the slats and adjust their local support height. Each adjusting module contains a corresponding sensor module, and a hydraulic and control system is connected to each adjusting module and its corresponding sensor module, constructing an intelligent support system with self-sensing and active adjustment capabilities. The working principle of this system is as follows: 1. During bearing operation, each adjustment module is located between the bearing housing and the slats, serving as a variable support foundation for the slats.

[0034] 2. When the shaft rotates, the sensor unit collects operating parameters such as local load, hydraulic chamber pressure and diaphragm displacement in each circumferential region of the bearing in real time, and sends the data to the control system.

[0035] 3. The control system determines whether there are problems such as uneven load, shaft misalignment or uneven water film based on the stress conditions of each area and the preset algorithm, and automatically calculates the required support force distribution.

[0036] 4. The control system applies different pressures to each adjustment module cavity through a proportional solenoid valve group, causing slight changes in the thickness of the adjustment module, which in turn causes the upper slats to rise or fall locally, thereby changing the support state of the journal.

[0037] 5. Through the coordinated adjustment of multiple adjustment modules, the bearing achieves dynamic shaft center adjustment and local flexible support during operation, effectively compensating for abnormal contact and uneven wear caused by off-center load, shaft deflection or low-speed impact.

[0038] 6. When the system detects an abnormal increase in local pressure, the control system can automatically open the pressure relief channel to release the internal pressure of the cavity and ensure the safety of the diaphragm and the shell.

[0039] This system can maintain stable support force under conditions such as start-up, shutdown, low-speed operation, and sudden load changes, achieving continuous water film lubrication and improving the operating stability and service life of the bearing.

[0040] The local support force can be adjusted according to the operating status of the shaft system, thereby reducing uneven wear and maintaining water film lubrication.

[0041] The adjustment module has an arc-shaped structure and matches the arc-shaped cavity. The adjustment module includes a module housing 3-3 and a flexible sealing diaphragm. The module housing has a sealing groove, and the flexible sealing diaphragm is fixed to the side wall of the sealing groove by adhesive. The module housing is used to bear axial load and fix the flexible sealing diaphragm. The flexible sealing diaphragm and the sealing groove constitute the sealing cavity. The sensor module is installed at the bottom of the sealing cavity.

[0042] A flexible sealing diaphragm, made of highly elastic and corrosion-resistant material, is positioned above the sealed cavity. It undergoes slight deformation in response to cavity pressure, causing changes in the support height of the slats. By altering the pressure within the sealed cavity, the flexible sealing diaphragm can be bulged out or retracted into the cavity, thus adjusting the thickness of the adjustment module.

[0043] Example 2 Based on Example 1, in order to improve the support of the flexible sealing diaphragm at the sealing cavity, the module housing of a single adjustment module is provided with two sealing grooves, and a matching flexible sealing diaphragm is fixedly installed in each sealing groove; a support part is provided between the two sealing grooves, and the support part and the module housing are integrally formed; a connecting hole for connecting the two sealing grooves is provided on the support part, and the plate is supported by the support part, which is used to limit deformation and bear axial load.

[0044] In Examples 1-2, preferably, the flexible sealing diaphragm is made of a highly elastic and corrosion-resistant material, which undergoes slight deformation in response to the pressure of the sealing cavity and pushes the slats to produce changes in support height.

[0045] In Examples 1-2, the sensor module includes a load sensor, a pressure sensor, and a displacement sensor. The sensor module is used to collect load, cavity pressure, and diaphragm displacement information and feed it back to the control system via a data bus. The control system dynamically adjusts the pressure within the module according to the operating parameters fed back by the sensors of each adjustment module, forming a controllable flexible support array.

[0046] In embodiments 1-2, the hydraulic system includes a main circuit 4-1 and several branch circuits 4-2 connected in parallel to the main circuit. A hydraulic pump 4-3 is provided on the main circuit, and a valve group 4-4 is provided on each branch circuit. Each branch circuit is connected to the sealed cavity of an adjustment module.

[0047] The hydraulic system is composed of a hydraulic pump, valve assembly, and piping network (main circuit and branch circuit) connecting various modules. The hydraulic pump provides the working medium of the system and has certain flow and pressure regulation capabilities. The valve assembly controls the inlet and outlet of the sealed cavity of the corresponding regulating module and supports independent control by the control system. When the cavity pressure is abnormal, the valve assembly opens the pressure relief path to ensure the safety of the flexible sealing diaphragm and the regulating module.

[0048] In Examples 1-2, the control system is an integrated control unit, including a signal acquisition module, a control logic module, and an instruction execution module; it has the following functions: real-time acquisition of sensor module data and determination of the load state of each adjustment module; analysis of load distribution or flexible sealing diaphragm displacement to determine whether there are problems such as off-center load or shaft misalignment; issuing instructions to control the valve group opening, adjusting the pressure in the sealed cavity, and dynamically changing the support height; closed-loop system control to maintain the stability of the shaft system position and optimize the distribution of support force.

[0049] In embodiments 1-2, the bearing housing consists of an upper housing 1-1 and a lower housing 1-2, which are connected by bolts. The connected bearing housing is an integral cylindrical structure, with a cylindrical cavity located inside the cylindrical structure. The bearing housing is made of copper, capable of withstanding the radial load of a large propulsion shaft system and mitigating seawater corrosion. A stop ring 7 is also provided at the end of the bearing housing for limiting the movement of the slats.

[0050] In embodiments 1-2, the first mounting grooves are equally spaced along the circumferential direction and equally spaced along the axial direction of the cylindrical cavity on the inner wall of the cylindrical cavity of the bearing housing.

[0051] During the operation of the ship's shafting system, the hydraulic pump provides a stable water supply, initially pre-pressurizing the sealed cavity of the regulating module. The control system collects load, pressure, and displacement information of each regulating module in real time. If the load in a certain area increases abnormally, the control logic adjusts the liquid pressure in the sealed cavity of the regulating module in that area, causing a slight reduction in the flexible sealing diaphragm, decreasing the local support stiffness, and simultaneously increasing the liquid pressure in the sealed cavity of the regulating module in the area with reduced load, thus maintaining the liquid pressure within the regulating module within the set range. If the sealed cavity pressure exceeds the limit or malfunctions, the pressure relief channel intervenes promptly to ensure structural safety. Continuous adjustment during operation ensures the stability of the flexible sealing diaphragm, uniform wear, and reduced off-center load.

[0052] When the liquid pressure in the regulating module is within a suitable range, if a tendency for uneven wear or shaft misalignment is detected, the system coordinates the liquid pressure in multiple regulating modules to achieve shaft adjustment.

[0053] Example 3 This invention also provides a bearing support control method, applied in any of the intelligent water-lubricated dynamically adjustable bearings shown above, the method comprising: During the operation of the ship's shafting system, the hydraulic pump provides a stable water supply, and in the initial stage, the sealed cavity of the adjustment module is pre-charged with a certain pressure; the control system collects the load, pressure and displacement information of each adjustment module in real time.

[0054] If the load in a certain area increases abnormally, the control logic adjusts the liquid pressure in the sealed cavity of the regulating module in that area, causing a slight decrease in the flexible sealing diaphragm and reducing the local support stiffness. Simultaneously, the load is increased to reduce the liquid pressure in the sealed cavity of the regulating module in the area where the load decreases, thus maintaining the liquid pressure within the regulating module within the set range. If the sealed cavity pressure exceeds the limit or malfunctions, the pressure relief channel intervenes promptly to ensure structural safety. During operation, continuous adjustment ensures the stability of the flexible sealing diaphragm, uniform wear, and reduced off-center load.

[0055] When the liquid pressure in the regulating module is within a suitable range, if a tendency for uneven wear or shaft misalignment is detected, the system coordinates the liquid pressure in multiple regulating modules to achieve shaft adjustment.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention.
