Description

Technical Field

[0001] This utility model relates to the technical field of sliding bearing testing mechanisms, specifically to a lubrication mechanism for testing sliding bearings to prevent oil leakage. Background Technology

[0002] As a key component in mechanical systems, the performance of sliding bearings directly affects the stability and reliability of equipment. With the development of industrial technology towards high speed, heavy load, and precision, higher demands are placed on the load-bearing capacity, friction characteristics, lifespan, and anti-interference capabilities of sliding bearings. Sliding bearing testing, by simulating actual working conditions, accurately measures key parameters such as the coefficient of friction, temperature rise, and wear, providing data support for bearing design optimization, material selection, and fault diagnosis.

[0003] In a published Chinese patent application (publication number CN210487269U), titled "A Test Chamber and Test Stand for a Tilting Pad Sliding Bearing," although the method uses strain gauge films embedded in the outer wall of a hollow input shaft and wireless strain nodes to transmit strain data generated by oil film pressure to a test computer to test the transient pressure value and pressure distribution of the oil film, this prior art has certain limitations in terms of the lubrication system. Its lubrication system's oil circulation, temperature control, and oil leakage prevention still need improvement. During actual testing, the high-speed rotation and applied load of the sliding bearing cause the internal temperature of the sliding bearing to rise. This prior art cannot effectively detect the temperature change of the lubricating oil inside the sliding bearing, nor can it effectively detect the rotational speed and load information of the rotating shaft, resulting in inaccurate test data. Therefore, a sliding bearing testing lubrication mechanism that can effectively solve the above problems is needed. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides a lubrication mechanism for testing and preventing oil leakage in sliding bearings, which has the following beneficial effects:

[0017] 1. This anti-leakage sliding bearing testing lubrication mechanism, through the coordinated arrangement of a temperature sensor, a level sensor, a first solenoid valve, and a second solenoid valve, enables precise control of lubricating oil temperature and level. During sliding bearing testing, the temperature and level of the lubricating oil significantly impact the accuracy of the test results. The temperature sensor monitors the lubricating oil temperature in real time. When the temperature exceeds a set threshold, the control board adjusts the oil pump speed based on the feedback signal from the temperature sensor, accelerating lubricating oil circulation and thus lowering the lubricating oil temperature, ensuring its stability during testing. Simultaneously, the level sensor monitors the lubricating oil level in the tank in real time. When the level falls below a set value, the control board controls the opening and closing of the first and second solenoid valves to automatically replenish the lubricating oil, ensuring an adequate supply. This precise control of lubricating oil temperature and level effectively solves the problem of inaccurate test data caused by the difficulty in accurately controlling lubricating oil temperature and level in existing technologies, improving the accuracy and reliability of sliding bearing testing.

[0018] 2. Through the coordinated design of the radial load assembly, speed sensor, and control board, this anti-leakage sliding bearing testing lubrication mechanism achieves precise control of load and speed. Precise control of load and speed is crucial for simulating actual working conditions during sliding bearing testing. The hydraulic rod and load sensor in the radial load assembly can accurately apply the radial load and monitor its magnitude in real time. When the load deviates from the set value, the control board adjusts the output force of the hydraulic rod based on the signal from the load sensor, thus achieving precise load control. Simultaneously, the speed sensor can detect the rotational shaft speed in real time, and the control board adjusts the motor speed based on the signal from the speed sensor, achieving precise control of the rotational shaft speed. This precise control of load and speed effectively solves the problem in existing technologies where precise load and speed control is difficult, leading to deviations between test results and actual working conditions, thereby improving the accuracy and reliability of sliding bearing testing.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: a leak-proof sliding bearing testing and lubrication mechanism, including a sliding bearing 6. The sliding bearing 6 includes a bearing housing 601, a bearing cover 602, an upper bearing shell 605, a lower bearing shell 606, and multiple bolts. The bearing cover 602 is fixedly mounted on the bearing housing 601 by multiple bolts, forming a cavity between the bearing cover 602 and the bearing housing 601. The upper bearing shell 605 and the lower bearing shell 606 are inserted into the cavity between the bearing cover 602 and the bearing housing 601 after being snapped together. The sliding bearing 6 also includes components such as oil seals. The structure and working principle of the sliding bearing 6 will not be described in detail here.

[0029] The anti-leakage sliding bearing testing lubrication mechanism also includes a workbench 1, sleepers 4, a loading component, an oil measuring component, and a control board 5. The control board 5 and sleepers 4 are both fixedly mounted on the workbench 1, and the control board 5 is connected to the loading component and the oil measuring component respectively. The sliding bearing 6 is detachably mounted on the sleepers 4. The control board 5 contains logic control programs, timing control programs, and other software programs to meet the needs of automated control of the loading component and the oil measuring component, and to meet the needs of adjusting control parameters, thereby improving the accuracy and efficiency of the test.

[0030] The loading component includes a rotating shaft 7, a radial load assembly, a motor 9, and a speed sensor. The rotating shaft 7 is inserted into the sliding bearing 6 and the two are slidably connected. Both the motor 9 and the radial load assembly are mounted on the worktable 1. The motor 9 is drive-connected to the rotating shaft 7, driving the rotating shaft 7 to rotate at high speed. The radial load assembly is also drive-connected to the rotating shaft 7, applying a radial force to it. The speed sensor is mounted on the worktable 1 and detects the rotational speed of the rotating shaft 7. The loading component can accurately simulate the load and speed conditions of the sliding bearing 6 under actual working conditions, providing accurate working condition simulation for testing.

[0031] The oil measurement component includes a temperature sensor 12, an oil tank 2, an oil pump 3, and a level sensor 16. The temperature sensor 12 is detachably mounted on the sliding bearing 6 and measures the internal temperature of the sliding bearing 6. The oil inlet of the oil pump 3 is connected to the inside of the oil tank 2, and the oil outlet of the oil pump 3 is connected to the inside of the sliding bearing 6. The level sensor 16 is installed inside the oil tank 2. The bottom of the internal cavity of the sliding bearing 6 is connected to the oil tank 2. The oil tank 2 is fixedly mounted on the workbench 1, and the oil pump 3 is mounted on the oil tank 2.

[0032] The workbench 1 provides a stable support platform for the entire mechanism, ensuring the stability of each component during testing. Sleepers 4 support and fix the sliding bearing 6, facilitating the installation and connection of the loading and oil measurement components. The motor 9 provides power, driving the rotating shaft 7 to rotate at high speed. Its speed can be precisely controlled by the control board 5 to meet the needs of different testing conditions. The radial load assembly applies radial force to the rotating shaft 7, simulating load conditions under actual working conditions. The load can be precisely adjusted by the control board 5 to ensure testing accuracy. A speed sensor detects the rotational speed of the rotating shaft 7 in real time and feeds the signal back to the control board 5. The control board 5 adjusts the speed of the motor 9 based on the feedback signal, achieving precise control of the rotating shaft 7's speed. The speed sensor uses one of the following: a photoelectric speed sensor or a Hall effect speed sensor. The oil measurement component can monitor the temperature and level of the lubricating oil inside the sliding bearing 6 in real time. By precisely controlling the temperature and level of the lubricating oil, the stability of the lubricating oil state during testing is ensured, improving the accuracy and reliability of the test. Temperature sensor 12 monitors the temperature of the lubricating oil inside the sliding bearing 6 in real time and feeds the temperature signal back to control board 5. When the temperature exceeds a set threshold (the temperature threshold varies depending on room temperature and rotation speed; therefore, this technical solution does not define the temperature threshold or other parameters numerically), control board 5 adjusts the rotation speed of oil pump 3 according to the feedback signal. Oil pump 3 delivers lubricating oil, accelerating its circulation and thus lowering its temperature, ensuring the stability of the lubricating oil temperature during testing. Oil tank 2 stores lubricating oil, providing a lubricating oil source for sliding bearing 6. Level sensor 16 monitors the lubricating oil level in oil tank 2 in real time to ensure a sufficient supply of lubricating oil. Oil pump 3 delivers the lubricating oil from oil tank 2 to the sliding bearing 6; its rotation speed can be adjusted by control board 5 to meet the lubricating oil flow requirements under different testing conditions. Level sensor 16 monitors the lubricating oil level in oil tank 2 in real time. When the level is lower than a set value, control board 5 controls the opening and closing of the first and second solenoid valves to automatically replenish the lubricating oil, ensuring a sufficient supply.

[0033] Specifically, the oil measuring component also includes a first oil pipe 13 and a second oil pipe 14. One end of the first oil pipe 13 is detachably installed to the oil outlet of the sliding bearing 6, and the other end is fixedly installed to the oil tank 2. The first oil pipe 13 is connected to the internal cavity of the sliding bearing 6 and the oil tank 2. The height of the first oil pipe 13 is lower than the height of the sliding bearing 6. One end of the second oil pipe 14 is detachably installed to the oil inlet of the sliding bearing 6, and the other end is fixedly installed to the oil outlet of the oil pump 3. The second oil pipe 14 is connected to the internal cavity of the sliding bearing 6 and the oil pump 3. A first electrically controlled valve is installed on the first oil pipe 13, and a second electrically controlled valve is installed on the second oil pipe 14. The temperature measuring element 12 is a temperature sensor. The control board 5 is electrically connected to the temperature measuring element 12, the oil pump 3, the liquid level sensor 16, the first electrically controlled valve, and the second electrically controlled valve, including communication connections.

[0034] The lubricating oil is circulated through the first oil pipe 13 and the second oil pipe 14. The first and second electrically controlled valves can precisely control the flow rate of the lubricating oil, further improving the stability of the lubricating oil condition. The first oil pipe 13 discharges the lubricating oil inside the sliding bearing 6 back to the oil tank 2, realizing the recycling of the lubricating oil. Its height is lower than that of the sliding bearing 6, which facilitates the smooth return of the lubricating oil. The second oil pipe 14 delivers the lubricating oil supplied by the oil pump 3 to the sliding bearing 6, providing lubricating oil for the sliding bearing 6. The first and second electrically controlled valves, controlled by the control board 5, can precisely adjust the flow rate of the lubricating oil, ensuring the reasonable flow of the lubricating oil inside the sliding bearing 6, further improving the stability of the lubricating oil condition.

[0035] Specifically, the radial load assembly includes a gantry frame 8, a hydraulic rod 11, and a sleeve 10. The gantry frame 8 is fixedly mounted on the worktable 1, the hydraulic rod 11 is fixedly mounted on the gantry frame 8, and the sleeve 10 is fitted onto the outer side wall of the end of the rotating shaft 7, with the two rotatably connected. The output shaft end of the hydraulic rod 11 is fixedly mounted to the outer side wall of the sleeve 10. The radial load assembly also includes a load sensor, which is fixedly mounted on the output shaft end of the hydraulic rod 11, and the sensing end of the load sensor is fixedly connected to the outer side wall of the sleeve 10. The control board 5 is electrically connected to the motor 9 and the load sensor, including a communication connection.

[0036] The hydraulic rod 11 and sleeve 10 work together to precisely apply radial loads. A load sensor monitors the load magnitude in real time, further improving load control accuracy. The gantry 8 provides mounting support for the hydraulic rod 11, ensuring its stability and reliability. The hydraulic rod 11 applies radial force to the rotating shaft 7, simulating actual working conditions. The output shaft end of the hydraulic rod 11 is fixedly installed to the sleeve 10, transmitting the radial force to the sleeve 10, which in turn transmits it to the rotating shaft 7, acting on the sliding bearing 6. The sleeve 10 transmits the radial force applied by the hydraulic rod 11 to the rotating shaft 7 while ensuring its normal rotation. The load sensor monitors the load magnitude in real time and feeds the signal back to the control board 5. The control board 5 adjusts the output force of the hydraulic rod 11 based on the feedback signal, achieving precise load control.

[0037] Specifically, the control board 5 adopts one of the following: a programmable logic controller, a microprocessor, or an industrial computer.

[0038] The control board 5 is electrically connected to the temperature measuring element 12, oil pump 3, liquid level sensor 16, first solenoid valve, second solenoid valve, motor 9, and load sensor, enabling automated control and coordination of each component, thus improving the accuracy and efficiency of the test. The control board 5 is equipped with logic control and timing control programs. Based on the signals fed back from each sensor, it precisely controls the actuators such as motor 9, oil pump 3, and hydraulic rod 11, achieving precise control of parameters such as load, speed, lubricating oil temperature, and liquid level, ensuring the stability and accuracy of the test process.

[0039] The oil tank 2 has a filler port 15. The oil pump 3 is one of the following: a vane pump or a gear pump.

[0040] In use, first install the sliding bearing 6 on the sleeper 4, unscrew the oil filler plug 603 and temperature measuring plug 604 on the bearing cover 602, and install the end of the second oil pipe 14 away from the oil pump 3 at the position where the oil filler plug 603 with the bearing cover 602 is removed; install the temperature measuring element 12 at the position where the temperature measuring plug 604 is removed on the bearing cover 602. Fix the end of the first oil pipe 13 away from the oil tank 2 to the bearing seat 601.

[0041] The control board 5 starts the motor 9, which drives the rotating shaft 7 to rotate at high speed. Simultaneously, the radial load assembly applies radial force to the rotating shaft 7, simulating actual working conditions. During the test, the temperature sensor 12 monitors the temperature of the lubricating oil inside the sliding bearing 6 in real time. When the temperature exceeds a set threshold, the control board 5, based on the signal from the temperature sensor 12, starts and adjusts the speed of the oil pump 3 to lower the lubricating oil temperature. The level sensor 16 monitors the lubricating oil level in the oil tank 2 in real time. When the level is lower than a set value, the control board 5 controls the opening and closing of the first and second solenoid valves to automatically replenish the lubricating oil. This precise control of lubricating oil temperature and level effectively solves the problem of inaccurate test data caused by the difficulty in accurately controlling lubricating oil temperature and level in existing technologies, improving the accuracy and reliability of sliding bearing testing.

[0042] Simultaneously, the load sensor monitors the load magnitude in real time. When the load deviates from the set value, the control board 5 adjusts the output force of the hydraulic rod 11 based on the signal from the load sensor, achieving precise load control. The speed sensor detects the rotational speed of the rotating shaft 7 in real time. Based on the signal from the speed sensor, the control board 5 adjusts the speed of the motor 9, achieving precise control of the rotational speed of the rotating shaft 7. This precise control of load and speed effectively solves the problem in existing technologies where precise control of load and speed leads to deviations between test results and actual working conditions, improving the accuracy and reliability of sliding bearing testing.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
