Description

Technical Field

[0001] The invention relates to the technical field of motor testing, in particular to a high-speed motor testing system. Background Art

[0002] At present, high-speed motors are widely used in various industrial fields, such as aerospace, automobiles, robots, and high-end manufacturing. These motors usually have the characteristics of high speed, high power, and high efficiency, and are widely used in application scenarios requiring high precision and high response speed. In order to ensure the long-term stable operation of high-speed motors, it is particularly important to conduct systematic and comprehensive testing. Existing high-speed motor test systems generally focus on measuring the basic operating data of the motor, such as spindle temperature, current change, speed, etc., to evaluate the basic performance of the motor under normal working conditions. These data provide an important reference for the basic performance of the motor, but fail to cover the actual performance of high-speed motors in complex application environments.

[0003] Existing test systems can usually only simulate the basic working conditions of high-speed motors, such as the temperature, current and speed of the motor under standard conditions. However, in actual applications, high-speed motors often work in various complex environments, such as under different load conditions, specific vibration directions and angles, or under the influence of environmental factors such as specific gases and pressures. These environmental factors will not only affect the working performance of the motor, but may also affect the thermal management, mechanical structure stability, life and other aspects of the motor. Therefore, existing test equipment and methods have failed to effectively simulate these complex environments, resulting in test results that cannot fully reflect the performance of the motor in actual applications.

[0004] For example, in practical applications, high-speed motors are often faced with vibration interference from different directions of the surrounding environment. Traditional test equipment is usually unable to simulate and test the vibration effects of the motor in multiple directions such as horizontal and vertical directions, and it is difficult to fully evaluate the impact of these vibrations on the internal structure, transmission system and performance of the motor. At the same time, load changes are also a key factor in motor operation. Existing test systems mostly focus on simulating constant load conditions and fail to fully consider the dynamic response of the motor under different load changes.

[0005] Therefore, the existing high-speed motor test system is in urgent need of a test platform that can more realistically and comprehensively simulate the various complex environments that high-speed motors may encounter in actual applications. Summary of the invention

The cover door 22 is hingedly assembled to the operation opening 21. The protective cover 2 can be sealed in the closed state. After air with specific temperature and humidity is introduced into it, various operating environments of the high-speed motor 5 can be accurately simulated.

[0061] In order to ensure that the assembly seat 32 can be stably assembled in the test machine 31 in a rotating manner around its own vertical axis and effectively transmit the vibration effect, and to ensure that the high-speed motor 5 can be stably installed on the test machine 31, the following technical solutions are provided:

[0066] Example 3

[0067] See also Figure 4-Figure 6 In order to ensure that the horizontal vibration mechanism can be stably installed and operated in the assembly seat 32 and produce horizontal vibration, the following technical solutions are provided:

[0068] An upper assembly cavity 321 is provided in the assembly seat 32, and the horizontal vibration mechanism includes a counterweight seat A331, a driving disk A332, a connecting rod A333, a driving motor A334, and a transmission shaft 335. The counterweight seat A331 is slidably installed in the upper assembly cavity 321 and slides back and forth in the horizontal direction. The driving disk A332 is rotatably installed in the upper assembly cavity 321 and is coaxially arranged with the assembly seat 32. The two ends of the connecting rod A333 are respectively hinged to the outer edge of the driving disk A332 and the counterweight seat A331. The transmission shaft 335 is fixedly connected to the driving disk A332 and extends to the bottom of the assembly seat 32. The driving motor A334 is fixedly installed on the assembly bottom cover 313 and is dynamically connected to the transmission shaft 335.

[0069] The setting of the upper assembly cavity 321 can ensure that the counterweight seat A331, the driving disk A332 and the connecting rod A333 are stably installed therein, ensure that the counterweight seat A331 and the driving disk A332 respectively operate stably in the set manner, and avoid spatial motion interference with the connecting rod A333.

[0070] When the driving motor A334 drives the driving disc A332 to operate through the transmission shaft 335, it can drive the counterweight seat A331 to reciprocate within a set operating trajectory through the connecting rod A333, thereby generating continuous and stable horizontal vibration.

[0071] In order to ensure that the vertical vibration mechanism can be stably installed and operated in the assembly seat 32 and produce vertical vibration, the following technical solutions are provided:

[0072] A lower assembly cavity 322 arranged in the upper assembly cavity 321 is opened in the assembly seat 32, and the vertical vibration mechanism includes a counterweight seat B341, a driving disk B342, a connecting rod B343, a driving motor B344, and a transmission sleeve 345. The counterweight seat B341, the driving disk B342, and the connecting rod B343 all include two groups arranged symmetrically. The counterweight seat B341 is slidably installed in the lower assembly cavity 322 and reciprocates in the vertical direction. The driving disk B342 is rotatably installed in the lower assembly cavity 322. The two ends of the connecting rod B343 are respectively hinged to the outer edge of the driving disk B342 and the counterweight seat B341. The transmission sleeve 345 is rotatably installed at the axis center of the assembly seat 32 and is arranged on the periphery of the transmission shaft 335. The two groups of driving disks B342 maintain transmission connection with the transmission sleeve 345. The driving motor B344 is fixedly installed on the assembly bottom cover 313 and is dynamically connected to the transmission sleeve 345.

[0073] The setting of the lower assembly cavity 322 can ensure that the two sets of counterweight seats B341, drive disks B342 and connecting rods B343 are stably installed therein, ensuring that the counterweight seats B341 and drive disks B342 respectively operate stably in the set manner and avoiding spatial motion interference of the connecting rod B343.

[0074] The transmission sleeve 345 is arranged on the periphery of the transmission shaft 335 and also extends to the bottom of the assembly seat 32 , so that the transmission sleeve 345 and the transmission shaft 335 can rotate freely in a relatively independent manner.

[0075] When the driving motor B344 drives the transmission sleeve 345 to operate, it can simultaneously drive the two sets of driving disks B342 to rotate stably, and then drive the corresponding counterweight seat B341 to move up and down stably in the vertical direction through the corresponding connecting rod B343, thereby generating continuous and stable vertical vibration.

[0076] In order to ensure that the drive motor A334 and the drive motor B344 can respectively realize power connection with the transmission shaft 335 and the transmission sleeve 345, and ensure that the transmission sleeve 345 can stably transmit power to the two sets of drive discs B342, the following technical solutions are provided:

[0077] A driving bevel gear A3341 is fixedly connected to the output shaft of the driving motor A334, and a driving bevel gear A3351 that meshes with the driving bevel gear A3341 is fixedly connected to the bottom of the transmission shaft 335; a driving bevel gear B3441 is fixedly connected to the output shaft of the driving motor B344, and a driving bevel gear B3451 that meshes with the driving bevel gear B3441 is fixedly connected to the bottom of the transmission sleeve 345, and a driving bevel gear b3452 arranged in the lower assembly cavity 322 is fixedly connected to the top of the transmission sleeve 345, and a driving bevel gear b3421 that meshes with the driving bevel gear b3452 is fixedly connected to the two sets of driving disks B342.

[0078] Since the transmission shaft 335 and the transmission sleeve 345 maintain rotational coordination, the transmission shaft 335 and the transmission sleeve 345 can be guaranteed to operate independently. When the drive motor A334 is working, the drive bevel gear A3341 and the transmission bevel gear A3351 can drive the transmission shaft 335 and the drive disk A332 to operate stably.

[0079] When the driving motor B344 is working, it can drive the transmission sleeve 345 to operate stably through the driving bevel gear B3441 and the transmission bevel gear B3451, and the transmission sleeve 345 can drive the driving disk B342 to operate stably through the combination of the driving bevel gear b3452 and the transmission bevel gear b3421.

[0080] Example 4

[0081] See also Figure 4 , Figure 7 In order to ensure that the horizontal angle adjustment mechanism can drive the assembly seat 32 to operate stably, so as to achieve accurate adjustment of the specific vibration direction of the horizontal vibration, and at the same time avoid the vibration effect affecting the accuracy of the angle adjustment, the following technical solution is provided.

[0082] The horizontal angle adjustment mechanism includes a driving motor C351, a driving bevel gear C352, a transmission bevel gear C353, and a matching combination of a worm wheel A354 and a worm A355. The driving motor C351 is fixedly mounted on the assembly bottom cover 313, the worm A355 is fixedly connected to the output shaft of the driving motor C351, the worm wheel A354 is coaxially fixedly connected to the driving bevel gear C352, and the transmission bevel gear C353 is fixedly connected to the bottom axis of the assembly seat 32 and meshes with the driving bevel gear.

[0083] When the driving motor C351 is running, it can drive the worm A355 to operate stably, and then drive the worm wheel A354 and the driving bevel gear C352 to operate, and then drive the transmission bevel gear C353 and the assembly seat 32 to rotate synchronously, so as to adjust the horizontal angle of the reciprocating motion direction of the counterweight seat A331.

[0084] Since the combination of worm wheel A354 and worm A355 has a self-locking property, that is, the power at the worm A355 end can be transmitted to the worm wheel A354 and drive the worm wheel A354 to operate stably, while the power at the worm wheel A354 end cannot be reversely transmitted to the worm A355 to achieve the self-locking of the mechanism. Therefore, when the horizontal angle adjustment mechanism is affected by vibration, the self-locking property of the worm wheel A354 and worm A355 can ensure that the assembly seat 32 is always maintained at a specific rotation angle.

[0085] It should also be noted that when the horizontal angle adjustment mechanism drives the assembly seat 32 to operate, it will synchronously drive the transmission bevel gear A3351 and the transmission bevel gear B3451 to operate. Therefore, it is necessary to ensure that the drive motor A334 and the drive motor B344 are in a stopped state to avoid interference with the drive motor A334 and the drive motor B344 caused by the operation of the horizontal angle adjustment mechanism.

[0086] Example 5

[0087] See also Figure 8-Figure 11 In order to ensure that the reversing mechanism 42 can be stably installed on the mounting bracket 12 and drive the adjustment seat 41 to rotate so as to adjust the angle of the load applying mechanism 43, the following technical solution is provided.

[0088] A balancing seat 411 is fixedly installed on the adjusting seat 41, and the load applying mechanism 43 and the balancing seat 411 are respectively arranged on both sides of the axis of the adjusting seat 41. The reversing mechanism 42 includes a driving motor D421, a driving bevel gear D422, a transmission bevel gear D423, and a matching combination of a worm wheel B424 and a worm B425. The driving motor D421 is fixedly installed on the mounting bracket 12, the driving bevel gear D422 is coaxially fixedly connected with the worm wheel B424 and rotatably installed on the mounting bracket 12, the worm B425 is fixedly connected to the output shaft of the driving motor D421, and the transmission bevel gear D423 is fixedly installed on the adjusting seat 41 and meshingly connected with the driving bevel gear D422.

[0089] The balancing seat 411 and the load applying mechanism 43 maintain weight balance, thereby ensuring that the adjustment seat 41 can stably rotate around its own horizontal axis, so as to ensure that the load applying mechanism 43 can achieve linkage combination with the tested high-speed motor 5.

[0090] When adjusting the angle of the adjustment seat 41 and the load applying mechanism 43, the driving motor D421 drives the worm B425 to operate, and then drives the worm wheel B424 and the driving bevel gear D422 to operate stably, so as to drive the transmission bevel gear, the adjustment seat 41 and the assembled load applying mechanism 43 to operate stably. In this process, the worm wheel B424 and the worm B425 also have self-locking characteristics. After the angle adjustment of the load applying mechanism 43 is completed, the driving motor D421 stops, and the adjustment seat 41 can be automatically locked to ensure the stability of the load applying mechanism 43.

[0091] In order to ensure that the load applying mechanism 43 can be stably installed on the adjustment seat 41 and that the load applying mechanism 43 can provide a specific load, the following technical solutions are provided:

[0092] The adjusting seat 41 is fixedly connected with an assembly bracket 412, and the load applying mechanism 43 includes an assembly cover 431, a rotating seat 432, a counterweight seat C433, an electric telescopic cylinder 434, and a load motor 435. The assembly cover 431 is fixedly installed on the assembly bracket 412, the rotating seat 432 is rotatably installed in the assembly cover 431 and is linked with the tested high-speed motor 5, the counterweight seat C433 includes a plurality of groups slidably installed in the rotating seat 432 and slidingly running in the radial direction, and the electric telescopic cylinder 434 is fixedly installed in the assembly cover 431 and is linked with the rotating seat 4 The rotating seat 432 is coaxially arranged with a telescopic shaft 4321 at the axis of the rotating seat 432 in a relatively sliding and rotating manner. The telescopic shaft 4321 is hinged with the counterweight seat C433 through a connecting rod C4331. The movable end of the electric telescopic cylinder 434 is fixedly connected to the telescopic shaft 4321. The load motor 435 is fixedly installed in the assembly cover 431. A driving bevel gear E4351 is fixedly connected to the output shaft of the load motor 435. A transmission bevel gear E4322 that meshes with the driving bevel gear E4351 is fixedly connected to the axis of the rotating seat 432.

[0093] The setting of the assembly bracket 412 can ensure that the load applying mechanism 43 is stably installed on the adjustment seat 41, and the setting of the assembly cover 431 can integrate and assemble the various components in the load applying mechanism 43. By controlling the telescopic movement of the electric telescopic cylinder 434, the telescopic shaft 4321 and the connecting rod C4331 can drive each group of counterweight seats C433 to slide radially along the rotating seat 432, thereby realizing the distribution and adjustment of the weight of the rotating seat 432.

[0094] When the load motor 435 is working, the combination of the driving bevel gear E4351 and the transmission bevel gear E4322 drives the rotating seat 432 and the counterweight seat C433 therein to operate synchronously, thereby generating a large rotational inertia.

[0095] The rotating seat 432 and the output shaft of the tested high-speed motor 5 are linked together by a magnetic coupler to achieve a non-rigid connection between the two, thereby preventing the load motor 435 or the high-speed motor 5 from being forced to stop and being damaged.

[0096] Through the load effect applied by the load motor 435, the performance of the high-speed motor 5 under various load conditions can be effectively tested.
