Description

Technical Field

[0001] The invention relates to the technical field of bearing rotation testing, and in particular to a high-speed rotation testing device and method for a long-life bearing based on a particle swarm algorithm. Background Art

[0002] Bearing test is an indispensable and important verification process in the design and manufacturing process of bearings. On the bearing tester, the actual installation condition and actual operating state of the bearing, that is, the bearing speed, axial load, radial load, ambient temperature, lubrication state, etc., are given according to the actual operating conditions to operate the bearing until the predetermined life or bearing failure is achieved. In the process of bearing experiment, multiple states need to be simulated, especially the instantaneous overload simulation. Many mechanical equipment will encounter non-continuous and sudden high load conditions during operation, such as starting, braking, impact load, etc. When simulating instantaneous overload, a large amount of heat will be generated, which needs to be dissipated in time. However, when the current cooling system is in use, sensors are mostly used to detect the cooling water level in the cooling water tank. In the process of bearing detection, there are already a lot of sensor data that need to be observed and recorded. It is difficult to observe the changes in the cooling water level in time, and it is not easy to troubleshoot the fault point when the sensor data is wrong, which will lead to untimely cooling water supply.

[0003] For example, a high-speed grease testing machine disclosed in publication number CN105241808B exists, which uses a method in which sensor measurement data is centrally controlled by a computer control system. When the sensor data is wrong, it is difficult to find the fault point, which will lead to untimely cooling water supply;

[0004] Therefore, a high-life bearing high-speed rotation test device and method based on particle swarm algorithm are proposed. Summary of the invention

[0023] The present invention provides a high-life bearing high-speed rotation test device and method based on particle swarm algorithm. Compared with the prior art, it has the following beneficial effects:

[0024] (1) The high-life bearing high-speed rotation test device and method based on particle swarm algorithm are provided by setting a test bench, a bearing body, an electromagnetic loading block, a guide column, a main electromagnet, a fixed frame, a drive motor, a cover, a left speed-up gear, a middle speed-up gear, and a right speed-up gear. The bearing body to be tested is installed on the test bench, and the electromagnetic loading block is irregularly controlled to apply load to the bearing body by irregularly controlling the power supply of the electromagnet, thereby simulating the non-continuous and sudden high load conditions encountered by many mechanical equipment during operation, such as instantaneous overload conditions such as starting, braking, and impact loads. The fixed frame provides support force to the guide column, and the guide column provides support force to the main electromagnet and the electromagnetic loading block.

[0025] (2) The high-life bearing high-speed rotation test device and method based on particle swarm algorithm are provided with a cooling water tank, a water pump 1, a water inlet pipeline, a positioning rod, a positioning plate, a floating plate, a wire, a winding wheel, a rotating shaft 1, a left power-enhancing gear, a middle power-enhancing gear, a rotating shaft 2, a right power-enhancing gear, a rotating shaft 3, an upper bevel gear, a lower bevel gear, a threaded rod, a support plate, a positioning column, a sliding rod, a sliding block, a plug plate, a guide rod, a spring 1, a positioning plate, an extrusion plate, a counterweight, a return pipe, a heat dissipation water tank, a water pump 2, and a return pipeline. When the water pump 1 is started, the cooling water in the cooling water tank is transported to the electromagnetic loading block through the water inlet pipeline to dissipate the heat of the electromagnetic loading block. When the cooling water temperature rises, the water pump The second start-up transports the heated cooling water to the heat sink through the return pipe for cooling. During the process, the cooling water can be adaptively transported from the heat sink back to the cooling water tank. The cooling water circulation can effectively absorb and take away the heat. The heat is transferred to the heat sink by the flow of cooling water around the electromagnet coil, and finally dissipated into the air or further dissipated through other cooling media, keeping the electromagnetic loading block within a safe operating temperature range to prevent performance degradation or damage caused by overheating. At the same time, by adaptively controlling the flow of cooling water in the cooling water tank and the heat sink, there is no need for experimenters to manually add cooling water to the cooling water tank, which simplifies the operating steps and makes it easy to troubleshoot the fault point when a fault occurs.

[0026] (3) The high-life bearing high-speed rotation test device and method based on particle swarm algorithm are provided with a fixed plate, a support column, a pressure plate, an extrusion rod, a sliding plate, a spring 2, a toggle rod, a control switch, a magnet, an upper electromagnet, and a lower electromagnet. When the extrusion plate moves downward, it will simultaneously drive the support column to move downward, so that the extrusion plate can transport the water in the heat dissipation water tank to the cooling water tank through the return pipe, and then reset to the initial state under the joint action of the magnet, the upper electromagnet, and the lower electromagnet. The upper electromagnet and the lower electromagnet assist the extrusion plate to move up or down, thereby improving the reliability of the extrusion plate, ensuring that the water in the heat dissipation water tank is transported to the cooling water tank through the return pipe, so that the floating plate can be reset to the initial state. The circulation rate of the cooling water can be quickly adjusted according to the instantaneous temperature requirement of the electromagnetic loading block, thereby improving the cooling efficiency and response speed, reducing the complexity of installation and maintenance, and reducing potential leakage points. At the same time, by changing the magnetic strength of the upper and lower electromagnets and adjusting the speed of the extrusion plate when moving up and down, the time for the cooling water in the heat dissipation water tank to flow back to the cooling water tank can be controlled, thereby improving the flow rate of the cooling water.

[0043] Embodiment 2: The technical solution of this embodiment is different from that of Embodiment 1 in that: a water return component for assisting cooling water circulation is provided in the test bench 1, and the water return component includes:

[0044] A cooling water tank 2, fixedly mounted on the test bench 1, for containing cooling water;

[0045] The heat dissipation water tank 4 is fixedly installed on the test bench 1 to hold the heated cooling water. The heat dissipation water tank 4 is connected to the cooling water tank 2 through the return pipe 3. A water pump 1 21 is fixedly installed on the top of the cooling water tank 2. The water pump 1 21 is connected to the electromagnetic loading block 12 through the water inlet pipe 22. A water pump 2 41 is fixedly installed on the top of the heat dissipation water tank 4. The water pump 2 41 is connected to the electromagnetic loading block 12 through the return pipe 42.

[0046] A positioning rod 23 is fixedly installed in the cooling water tank 2, a baffle 24 is fixedly installed on the positioning rod 23, a floating plate 25 is slidably passed through the positioning rod 23, a wire 26 is fixedly installed on the top of the floating plate 25, a winding wheel 27 is fixedly installed on one end of the wire 26, the wire 26 is wound around the winding wheel 27, a rotating shaft 28 is fixedly installed on the side wall of the winding wheel 27, the rotating shaft 28 is movably installed in the test bench 1 through a bearing, a left power-enhancing gear 29 is fixedly installed on one end of the rotating shaft 28, a middle power-enhancing gear 210 is meshed on the left power-enhancing gear 29, the middle power-enhancing gear 210 is movably installed on the test bench 1 through a rotating shaft 211, a right power-enhancing gear 212 is meshed on the middle power-enhancing gear 210, and the right power-enhancing gear 212 is movably installed on the test bench 1 through a rotating shaft 3 213;

[0047] An upper bevel gear 214 is fixedly installed at one end of the rotating shaft 3 213, and a lower bevel gear 215 is meshed on the upper bevel gear 214. A threaded rod 216 is fixedly passed through the lower bevel gear 215. Both ends of the threaded rod 216 are movably installed on the test bench 1 through the bearing 2. A support plate 217 is threadedly passed through the threaded rod 216, and a positioning column 218 is slidably passed through the support plate 217. One end of the positioning column 218 is fixedly installed on the test bench 1. A sliding rod 219 is fixedly installed on the top of the support plate 217. The top of the sliding rod 219 is tilted, and the tilted top of the sliding rod 219 slides against a sliding block 220 with a bottom tilted.

[0048] A plug plate 221 is fixedly installed at one end of the sliding block 220, a guide rod 222 is slidably arranged in the plug plate 221, one end of the guide rod 222 is fixedly installed on the top of the heat dissipation water tank 4, a spring 223 is fixedly installed on the side wall of the guide rod 222, and the other end of the spring 223 is fixedly installed in the plug plate 221;

[0049] One end of the plug plate 221 is tilted away from the guide rod 222, and a positioning plate 224 is slidably passed through one end of the plug plate 221. The bottom of the positioning plate 224 is fixedly installed on the top of the extrusion plate 225. Two counterweights 226 are fixedly installed on the top of the extrusion plate 225. The extrusion plate 225 is slidably installed in the heat dissipation water tank 4.

[0050] When in use, the cooling water in the cooling water tank 2 is transported to the electromagnetic loading block 12 through the water inlet pipe 22 by starting the water pump 1 21 to dissipate heat from the electromagnetic loading block 12. When the cooling water temperature rises, the heated cooling water is transported to the heat dissipation water tank 4 through the return pipe 42 by starting the water pump 2 41 to cool it down.

[0051] During the process, the water level in the cooling water tank 2 is continuously lowered, and the buoyancy of the floating plate 25 is continuously reduced. The floating plate 25 slides with the positioning rod 23, so that the floating plate 25 moves linearly along the positioning rod 23 until the bottom of the floating plate 25 contacts the top of the baffle 24 and reaches the lowest water level of the cooling water tank 2. The floating plate 25 moves by pulling the wire 26, so that the wire 26 is unwound from the winding wheel 27. The winding wheel 27 drives the rotating shaft 1 28 to rotate, and the rotating shaft 1 28 drives the left booster gear 29 to rotate. The left booster gear 29 drives the middle booster gear 210 to rotate. The rotating shaft 211 provides support for the middle booster gear 210. The middle booster gear 210 drives the right booster gear 212 to rotate, and the right booster gear 212 drives the rotating shaft 3 213 rotates, the rotating shaft 213 drives the upper bevel gear 214 to rotate, the upper bevel gear 214 drives the lower bevel gear 215 to rotate, the lower bevel gear 215 drives the threaded rod 216 to rotate, the threaded rod 216 and the support plate 217 are threadedly matched, the positioning column 218 and the support plate 217 are slidingly matched, so that the support plate 217 can move linearly along the positioning column 218 under the drive of the threaded rod 216, the support plate 217 drives the sliding rod 219 to move upward, the sliding rod 219 squeezes the sliding block 220 to move, so that the sliding block 220 drives the plug plate 221 to move, the plug plate 221 and the guide rod 222 are slidingly matched, so that the plug plate 221 moves linearly along the guide rod 222, so that the plug plate 221 slides out of the positioning plate 224;

[0052] When the plug plate 221 completely slides out of the positioning plate 224, the water level in the heat dissipation water tank 4 reaches the highest point. At this time, the extrusion plate 225 and the counterweight block 226 that have lost their limit move downward under the action of gravity, so that the cooling water in the heat dissipation water tank 4 breaks through the one-way valve installed on the return pipe 3 and flows back into the cooling water tank 2. At this time, the water level in the cooling water tank 2 rises again, the floating plate 25 returns to its original position, the torsion spring applies a force to the rotating shaft 28, and the wire 26 is wound around the winding wheel 27 again, waiting for the next use.

[0053] Embodiment 3, the technical solution of this embodiment is different from that of embodiment 2 in that: a reset component for assisting the operation of the water return component is also provided on the test bench 1, the reset component includes a fixed plate 43 fixedly installed in the heat dissipation water tank 4, a water pump 2 41 is fixedly installed on the top of the fixed plate 43 through a shell, a control switch 410 is fixedly installed on the top of the fixed plate 43, a lower electromagnet 413 is fixedly installed on the top of the fixed plate 43, an upper electromagnet 412 is fixedly installed in the test bench 1, and a magnet 411 is slidably connected to the bottom of the upper electromagnet 412, A support column 44 is fixedly installed at one end of the magnet 411, an extrusion plate 225 is fixedly installed at the bottom of the support column 44, a pressure plate 45 is fixedly installed on the side wall of the support column 44, an extrusion rod 46 is fixedly installed on the top of the pressure plate 45, the top of the extrusion rod 46 abuts against a sliding plate 47, a spring 2 48 is fixedly installed on the top of the sliding plate 47, the other end of the spring 2 48 is fixedly installed in the test bench 1, and a toggle rod 49 is fixedly installed at the bottom of the sliding plate 47. The positions of the pressure plate 45 and the toggle rod 49 are adapted to the control switch 410.

[0054] When in use, the heat dissipation water tank 4 provides support force to the fixing plate 43, and the extrusion plate 225 provides support force to the support column 44. When the extrusion plate 225 moves downward, it will simultaneously drive the support column 44 to move downward, and the support column 44 drives the pressing plate 45 and the magnet 411 to move synchronously;

[0055] When the extrusion plate 225 moves to the lowest state, the pressing plate 45 will toggle the control switch 410 to switch, so that the magnetism of the upper electromagnet 412 and the lower electromagnet 413 is converted into the magnetism of the upper electromagnet 412 and the magnet 411 being attracted to each other, and the magnetism of the lower electromagnet 413 and the magnet 411 being repelled from each other, so that the extrusion plate 225 transfers the water in the heat dissipation water tank 4 to the cooling water tank through the return pipe 3, and then resets to the initial state under the joint action of the magnet 411, the upper electromagnet 412, and the lower electromagnet 413;

[0056] When the pressing plate 45 is reset to the initial state, the sliding plate 47 is squeezed upward by the squeezing rod 46, and the sliding plate 47 drives the toggle rod 49 to move upward. The toggle rod 49 toggles the control switch 410 to switch, so that the magnetism of the upper electromagnet 412 and the lower electromagnet 413 is converted into the magnetism of the upper electromagnet 412 and the magnet 411 mutually repel each other, and the magnetism of the lower electromagnet 413 is attracted to the magnetism of the magnet 411. However, at this time, the plug plate 221 is again stuck in the positioning plate 224 under the action of the spring 223, so that the squeezing plate 225 cannot move. Until the cooling water level in the cooling water tank 2 drops to the minimum next time, the squeezing plate 225 will move downward under the joint action of the upper electromagnet 412 and the lower electromagnet 413, and the squeezing plate 225 is assisted by the upper electromagnet 412 and the lower electromagnet 413 to move up or down, thereby improving the reliability of the squeezing plate 225, and ensuring that the water in the heat dissipation water tank 4 is transported to the cooling water tank 2 through the return pipe 3, so that the floating plate 25 can be reset to the initial state.

[0057] The embodiment of the present invention also provides an operation method for a high-life bearing high-speed rotation test device based on a particle swarm algorithm, comprising the following steps:

[0058] S1, installing the bearing body 11 to be tested on the test bench 1;
