Description

Technical Field

[0001] This utility model relates to the field of permanent magnet transmission technology, and in particular to a magnetic wheel testing device. Background Technology

[0002] Permanent magnet drive technology has been widely used in the field of industrial transmission due to its advantages such as no mechanical wear, no need for lubrication, high transmission efficiency and overload protection. As the core actuator of permanent magnet drive system, the magnetic wheel's performance parameters such as transmission torque and speed adaptability directly determine the operational stability and reliability of the entire transmission system. Therefore, it is crucial to conduct accurate performance testing on the magnetic wheel.

[0003] However, existing magnetic wheel testing devices have the following problems: due to the fixed connection method, operators cannot flexibly adjust the relative distance between the driving wheel and the driven wheel in the horizontal direction, as well as the installation height of the driving wheel in the vertical direction. This makes it difficult for the same testing device to adapt to the testing requirements of different usage scenarios, and it is even more impossible to simulate the transmission performance under different distances. Moreover, the driving wheel and the driven wheel are generally fixedly connected to the corresponding rotating shaft, so the relative position of the wheel body cannot be adjusted, making operation inconvenient and further limiting the adaptability and convenience of the testing device.

[0004] Therefore, existing magnetic wheel testing devices suffer from poor adaptability, limited testing conditions, and inconvenient debugging. Thus, there is an urgent need for a magnetic wheel testing device to solve these technical problems. Utility Model Content

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Permanent magnet drive technology has been widely used in the field of industrial transmission due to its advantages such as no mechanical wear, no need for lubrication, high transmission efficiency and overload protection. As the core actuator of permanent magnet drive system, the magnetic wheel's performance parameters such as transmission torque and speed adaptability directly determine the operational stability and reliability of the entire transmission system. Therefore, it is crucial to conduct accurate performance testing on the magnetic wheel.

[0036] However, existing magnetic wheel testing devices have the following problems: due to the fixed connection method, operators cannot flexibly adjust the relative distance between the driving wheel and the driven wheel in the horizontal direction, as well as the installation height of the driving wheel in the vertical direction. This makes it difficult for the same testing device to adapt to the testing requirements of different usage scenarios, and it is even more impossible to simulate the transmission performance under different distances. Moreover, the driving wheel and the driven wheel are generally fixedly connected to the corresponding rotating shaft, so the relative position of the wheel body cannot be adjusted, making operation inconvenient and further limiting the adaptability and convenience of the testing device.

[0037] Therefore, existing magnetic wheel testing devices suffer from poor adaptability, limited testing conditions, and inconvenient debugging. Thus, there is an urgent need for a magnetic wheel testing device to solve these technical problems.

[0038] like Figures 1-6 As shown, this embodiment provides a magnetic wheel testing device, which includes a base 1, a power mechanism 2, and a driven mechanism 3. The power mechanism 2 is adjustablely connected to the base 1 along a first horizontal direction. The power mechanism 2 includes a rotation driver 21 and a driving wheel 22. The driving wheel 22 is adjustablely connected to the output end of the rotation driver 21 along a vertical direction. The rotation driver 21 can drive the driving wheel 22 to rotate around the vertical direction. The driven mechanism 3 includes a driven shaft 31 and a driven wheel 32. The driven shaft 31 is rotatably connected to the base 1 and configured to be connected to the testing mechanism. The driven wheel 32 is adjustablely connected to the driven shaft 31 along a second horizontal direction. When the driving wheel 22 rotates, it can drive both the driven wheel 32 and the driven shaft 31 to rotate around the second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to each other.

[0039] In this embodiment, the power mechanism 2 includes a rotary driver 21 and a driving wheel 22, and the driven mechanism 3 includes a driven shaft 31 and a driven wheel 32. The power mechanism 2 is adjustablely connected to the base 1 along a first horizontal direction, allowing operators to easily move the power mechanism 2 to adjust the horizontal position of the driving wheel 22 relative to the driven wheel 32. Furthermore, the driving wheel 22 is adjustablely connected to the output end of the rotary driver 21 along a vertical direction, allowing operators to adjust the height of the driving wheel 22 relative to the driven wheel 32. Moreover, the driven wheel 32 is adjustablely connected to the driven shaft 31 along a second horizontal direction, further allowing for flexible adjustment of the distance between the driving wheel 22 and the driven wheel 32, thus adapting to the transmission testing requirements of the driving wheel 22 and the driven wheel 32 at different distances. The rotary driver 21 can drive the driving wheel 22 to rotate in the vertical direction. When the driving wheel 22 rotates, it can drive both the driven wheel 32 and the driven shaft 31 to rotate in the second horizontal direction, thereby enabling performance testing of the driving wheel 22 and the driven wheel 32 through a testing mechanism. Furthermore, the first and second horizontal directions are perpendicular to each other to adapt to the practical application scenarios of orthogonal magnetic wheels. Through the above configuration, the magnetic wheel testing device of this application can more easily adjust the testing spacing, improving adaptability and convenience.

[0040] It should be noted that both the driving wheel 22 and the driven wheel 32 in this embodiment are magnetic wheels. Moreover, the testing mechanism in this embodiment includes, but is not limited to, a torque dynamometer, a speed dynamometer, or a comprehensive performance dynamometer, as long as it is convenient for detecting the magnetic wheel transmission performance parameters such as torque, speed, and power of the driven shaft 31. The specific structure of the testing mechanism is not limited in this regard.

[0041] The specific structure of the magnetic wheel testing device is described below:

[0042] Specifically, the power mechanism 2 also includes a sliding part 23, which is slidably connected to the base 1 along the first horizontal direction. The rotation driver 21 is disposed on the sliding part 23, which can realize the position adjustment of the rotation driver 21 along the first horizontal direction, thereby adjusting the horizontal distance between the driving wheel 22 and the driven wheel 32, so as to adapt to the test requirements of different test distances of the magnetic wheel.

[0043] Specifically, of the sliding part 23 and the base 1, one is provided with a sliding rod 11, and the other is provided with a slider 231 that slides in cooperation with the sliding rod 11. Through the sliding cooperation between the sliding rod 11 and the slider 231, it can be ensured that the sliding part 23 always moves stably along the first horizontal direction.

[0044] More specifically, in this embodiment, the sliding part 23 is an L-shaped base, and the rotation driver 21 is a servo motor. The servo motor is fixedly connected to the L-shaped base by bolts to improve the servo motor's installation stability. The output shaft of the servo motor is connected to the drive wheel 22 to drive the drive wheel 22 to rotate, thereby precisely controlling the speed of the drive wheel 22 to meet the magnetic wheel testing requirements under different speed conditions. The slide bar 11 is set on the base 1, and the slider 231 is set on the L-shaped base and slidably connected to the slider 231 to ensure that the L-shaped base can move along the first horizontal direction, thereby driving the servo motor and the drive wheel 22 to achieve precise movement.

[0045] In other embodiments, the slide bar 11 is disposed on the sliding part 23, and the slider 231 is disposed on the base 1, which can also achieve the above-mentioned function. The specific positions of the above components are not limited here. Moreover, the rotary driver 21 can also be a mechanical device such as a stepper motor, as long as it can stably drive the drive wheel 22 to rotate. The specific structure of the rotary driver 21 is not limited here.

[0046] Specifically, the base 1 is provided with a threaded portion 12 extending along the first horizontal direction. The threaded portion 12 is connected to the sliding portion 23. When the threaded portion 12 rotates, it drives the sliding portion 23 to slide relative to the base 1. The rotational motion of the threaded portion 12 is converted into the linear motion of the sliding portion 23, which can realize the mechanical adjustment of the position of the sliding portion 23. Not only is the adjustment process more labor-saving, but the displacement control is also more precise.

[0047] More specifically, in this embodiment, the threaded part 12 is a lead screw, which is rotatably mounted on the base 1. A ball nut is provided inside the sliding part 23, and the ball nut is fitted onto the lead screw. The lead screw and the ball nut are engaged by rolling balls. When the lead screw rotates, the balls roll along the threaded raceway of the lead screw, causing the ball nut to move linearly. This, in turn, drives the sliding part 23 to slide synchronously along the first horizontal direction with the ball nut, thereby achieving high-precision displacement adjustment of the power mechanism 2 and ensuring the accuracy of the magnetic wheel spacing adjustment. Moreover, by replacing the traditional threaded sliding fit with the above-mentioned arrangement, the frictional resistance between the lead screw and the sliding part 23 can be reduced, improving the smoothness of movement and adjustment accuracy of the sliding part 23, and avoiding adjustment jamming or loss of accuracy due to excessive friction.

[0048] In addition, the slide rod 11 is parallel to the lead screw, and there are two slide rods 11, which are respectively located on both sides of the lead screw, thereby providing balanced support and guidance for the sliding part 23, further improving the smoothness and straightness of the movement of the sliding part 23, and preventing the sliding part 23 from tilting or getting stuck during the movement.

[0049] Specifically, a manual wheel is provided at one end of the threaded part 12, so that the operator can rotate the manual wheel to drive the threaded part 12 to rotate, making the operation more labor-saving, convenient and quick. Moreover, the manual wheel has scale lines along its own circumference, and the operator can intuitively obtain the displacement of the sliding part 23 through the scale lines, and then quantitatively adjust the position of the power mechanism 2, thereby further improving the accuracy of the magnetic wheel spacing adjustment and avoiding test spacing adjustment errors.

[0050] Specifically, the power mechanism 2 also includes a drive shaft 24, which is coaxially connected to the output end of the rotary driver 21. The drive wheel 22 is sleeved on the outer peripheral wall of the drive shaft 24. By setting the drive shaft 24 as an intermediate component connecting the rotary driver 21 and the drive wheel 22, it can adapt to the installation requirements of drive wheels 22 of different specifications, avoiding the problem of poor installation compatibility caused by the direct connection of the output end of the rotary driver 21 to the drive wheel 22. Moreover, the above arrangement can ensure the coaxiality of the transmission between the drive shaft 24 and the output end of the rotary driver 21, avoiding eccentric vibration during transmission.

[0051] Specifically, the power mechanism 2 also includes a connector 25 and a limiting member 26. The connector 25 passes through the output end of the drive shaft 24 and the rotary driver 21 along the axial direction of the drive shaft 24. The limiting member 26 is located at the end of the connector 25 away from the rotary driver 21 and abuts against the drive shaft 24, thereby axially limiting the drive shaft 24 and preventing the drive shaft 24 from axially moving during rotation.

[0052] More specifically, in this embodiment, one end of the drive shaft 24 is sleeved on the outside of the output shaft of the servo motor. By increasing the contact area between the drive shaft 24 and the output shaft of the servo motor, the stability of their connection is improved. The connecting member 25 is a screw, and the limiting member 26 is a nut. Along the axial direction of the drive shaft 24, the screw passes through one end of the drive shaft 24 and connects to the output shaft of the servo motor. The nut is threadedly connected to one end of the screw, so that the nut abuts against the end face of one end of the drive shaft 24, thereby achieving axial limiting of the drive shaft 24. Moreover, the axial limiting of the drive shaft 24 is achieved by the cooperation of the screw and the nut, which not only has a simple structure and reliable limiting effect, but also facilitates disassembly and adjustment, making operation more convenient.

[0053] In other embodiments, the connector 25 is a screw and the limiting member 26 is a washer. Along the axial direction of the drive shaft 24, the screw passes through one end of the drive shaft 24 and is connected to the output shaft of the servo motor. The washer is sleeved on one end of the screw and sandwiched between the screw and the drive shaft 24. The above functions can also be achieved. The specific structure of the above components will not be limited here.

[0054] Specifically, the power mechanism 2 also includes a fastener 27, which passes through the drive shaft 24 radially and is connected to the output end of the rotary driver 21. Through the fixing effect of the fastener 27 in the radial direction of the drive shaft 24, the connection strength between the drive shaft 24 and the output end of the rotary driver 21 can be further improved.

[0055] More specifically, in this embodiment, the fastener 27 is a screw, which is threadedly connected to the drive shaft 24 and the output shaft of the servo motor along the radial direction of the drive shaft 24. This improves the connection stability between the drive shaft 24 and the servo motor, ensuring that the drive shaft 24 can rotate stably following the output shaft of the servo motor. Furthermore, the screw, as the fastener 27, is readily available and easy to install, reducing processing and assembly costs. In other embodiments, the fastener 27 may be a bolt or pin, achieving the same effect. Therefore, the specific structure of the fastener 27 is not limited here.

[0056] Specifically, the driving wheel 22 can slide along the axial direction of the driving shaft 24 and be clamped to the driving shaft 24, allowing the operator to flexibly adjust and fix the axial installation position of the driving wheel 22 on the driving shaft 24. And / or, the driven wheel 32 can slide along the axial direction of the driven shaft 31 and be clamped to the driven shaft 31, allowing the operator to flexibly adjust and fix the axial installation position of the driven wheel 32 on the driven shaft 31. Through the above settings, the operator can quickly and conveniently complete the position adjustment operations of the driving wheel 22 and the driven wheel 32, improving the debugging efficiency before testing, avoiding increased test preparation time due to cumbersome position adjustment operations, and reducing the ease of use of the testing device.

[0057] It should be noted that the driving wheel 22 and the driven wheel 32 can be clamped to the corresponding shafts (driving shaft 24 and driven shaft 31) by bolt clamping or clamping, and those skilled in the art know how to achieve the above methods, so no further limitations are made here.

[0058] Specifically, the power mechanism 2 also includes a first locking member, through which the drive wheel 22 is connected to the drive shaft 24; and / or, the driven mechanism 3 also includes a second locking member, through which the driven wheel 32 is connected to the driven shaft 31. This not only improves the connection strength between the drive wheel 22 and the drive shaft 24, and between the driven wheel 32 and the driven shaft 31, but also enables the detachable assembly of the drive wheel 22 on the drive shaft 24 and the driven wheel 32 on the driven shaft 31, making it convenient for operators to replace magnetic wheels of different specifications according to testing requirements.

[0059] It should be noted that the first locking component and / or the second locking component can be bolts, screws, or other components, as long as they can achieve the above-mentioned functions. No specific restrictions are placed on the specific structure of the above-mentioned components here.

[0060] Specifically, in this embodiment, the driven mechanism 3 further includes a bearing seat 33, which is disposed on the base 1. The driven shaft 31 is assembled on the base 1 through the bearing seat 33, so that the bearing seat 33 can provide stable rotational support for the driven shaft 31, reduce the frictional resistance during the rotation of the driven shaft 31, ensure the smoothness of the rotation of the driven shaft 31, and avoid torque test errors caused by excessive rotational resistance.

[0061] Furthermore, one end of the driven shaft 31 is inserted through the driven wheel 32, and the other end of the driven shaft 31 is connected to the test mechanism through the coupling 100 to compensate for the installation coaxiality error between the driven shaft 31 and the test mechanism, and to avoid transmission jamming or damage to the test mechanism caused by coaxiality deviation.

[0062] Specifically, the base 1 includes a support frame 13 and a transfer frame 14. The transfer frame 14 is detachably connected to the support frame 13. By setting both the power mechanism 2 and the driven mechanism 3 on the transfer frame 14, the power mechanism 2 and the driven mechanism 3 can be disassembled and assembled as a whole, which facilitates the transportation, installation and maintenance of the above-mentioned mechanisms.

[0063] More specifically, in this embodiment, the adapter frame 14 includes an adapter plate 141 and a U-shaped plate 142. The adapter plate 141 is detachably connected to the support frame 13 by bolts, and the U-shaped plate 142 is detachably connected to the adapter plate 141 by bolts. This not only improves the firmness of the connection between related components, but also makes disassembly and maintenance more convenient.

[0064] Furthermore, the U-shaped plate 142 has a horizontally extending mounting groove 1421 inside. The slide rod 11 and the lead rod are arranged vertically at intervals in the mounting groove 1421. The two ends of the slide rod 11 are respectively connected to the two opposing inner side walls of the mounting groove 1421, and the two ends of the lead rod are respectively rotatably connected to the two opposing inner side walls of the mounting groove 1421. The L-shaped base of the power mechanism 2 is connected to the slide rod 11 and the lead rod. Not only does the mounting groove 1421 improve the structural compactness of the device, but the sliding cooperation between the L-shaped base and the slide rod 11 and the lead rod also achieves the synchronicity and stability of the movement of the power mechanism 2, avoiding the power mechanism 2 from becoming loose or deviating during movement, which would affect the stability of the test process.

[0065] More specifically, the top of the adapter plate 141 is provided with a lifting lug 1411, which allows the operator to connect the lifting tool to the lifting lug 1411 to lift the entire adapter frame 14, thereby facilitating the installation, disassembly and transportation of the adapter frame 14.

[0066] Specifically, in this embodiment, the support frame 13 includes an L-shaped base plate 131 and two inclined support plates 132. The two support plates 132 are respectively disposed on both sides of the L-shaped base plate 131, and the two ends of the support plates 132 are respectively connected to the L-shaped base plate 131, thereby providing stable support for the L-shaped base plate 131, thus dispersing the force on the support frame 13 and improving the structural strength and stability of the support frame 13. Moreover, the adapter plate 141 is detachably connected to the L-shaped base plate 131 by bolts to facilitate the disassembly and maintenance of the adapter plate 141.

[0067] The specific working process of the magnetic wheel testing device is explained below:

[0068] Before conducting the performance test of the magnetic wheel, the operator first attaches the driving wheel 22 and the driven wheel 32 to the driving shaft 24 and the driven shaft 31 respectively, and then rotates the manual wheel to drive the lead screw to rotate. Since the lead screw and the ball nut are connected by rolling ball, when the lead screw rotates, the ball rolls along the thread raceway of the lead screw, which drives the ball nut to make linear motion, and then drives the sliding part 23 to slide synchronously with the ball nut along the first horizontal direction. During this process, the operator can accurately adjust the horizontal distance between the driving wheel 22 and the driven wheel 32 through the scale line on the manual wheel. Subsequently, the driving wheel 22 and the driven wheel 32 are slid to their target positions on their corresponding shafts (driving shaft 24 and driven shaft 31), and the driving wheel 22 is clamped to the driving shaft 24, and the driven wheel 32 is clamped to the driven shaft 31, thus completing the position adjustment before the test. Then, the driven shaft 31 is connected to the test mechanism through the coupling 100, and the driving wheel 22 is driven to rotate by the rotary driver 21. The driving wheel 22 drives the driven wheel 32 and the driven shaft 31 to rotate through magnetic coupling. Then, the test mechanism collects performance parameters such as torque and speed in real time to complete the single-condition test.

[0069] To test the performance of the magnetic wheels at different spacings and axial positions, the operator only needs to rotate the manual wheel again to adjust the horizontal position of the driving wheel 22, or loosen the first and second locking parts to adjust the axial positions of the driving wheel 22 and the driven wheel 32 on the corresponding shafts and then re-clamp them. This allows for quick switching of test conditions and the conduct of multiple sets of test experiments. After the test is completed, the rotary drive 21 is turned off until the driving wheel 22 and the driven wheel 32 stop rotating, thus completing the entire test process.

[0070] In the above process, the interaction between the ball screw and the drive wheel 22 enables rapid and quantitative adjustment of the horizontal distance, eliminating the need for repeated manual adjustments by operators. Furthermore, by loosening the first and second locking components, adjusting the axial positions of the drive wheel 22 and driven wheel 32 on their corresponding shafts, and then re-clamping them, the axial adjustment of the magnetic wheel can be achieved freely, eliminating the cumbersome steps of disassembling and assembling the magnetic wheel in traditional devices and significantly reducing the debugging time for a single set of magnetic wheels. Moreover, the ball screw and ball screw in this embodiment, through the rolling engagement of the balls, can control the horizontal distance adjustment accuracy to the 0.01mm level. Combined with the stability of the axial clamping of the magnetic wheel, this effectively avoids test data distortion caused by positional deviations. In addition, the combination of the large-stroke horizontal adjustment (0-300mm) of the ball screw and the free axial adjustment (0-150mm) of the magnetic wheel allows for testing of magnetic wheels of different specifications and installation sizes. In summary, the magnetic wheel testing device of this embodiment improves debugging efficiency, testing accuracy, and model compatibility through the above-described settings, achieving technical effects that traditional magnetic wheel testing devices could not have anticipated.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
