Description

Technical Field

[0001] This invention relates to a torque testing device, and more particularly to a torque testing device for a magnetic coupling. Background Technology

[0002] Magnetic couplings (also known as magnetic couplers or permanent magnet drive devices) are mechanical components that transmit torque non-contactly through a magnetic field. They are widely used in fields such as chemical, pharmaceutical, and food industries that require sealed transmission. Before leaving the factory, magnetic couplings need to undergo various performance tests, among which the torque test is a particularly important one. This test assesses their torque transmission performance, dynamic response, and durability, and verifies their design parameters and reliability by simulating actual working conditions.

[0003] Currently, conventional transmission component testing devices typically consist of the transmission component installed between the drive device and the loading device. Existing transmission component testing devices can only test the torque transmission capacity of magnetic transmission components under operating conditions, but cannot test the torque of magnetic couplings under misaligned conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a torque testing device for magnetic couplings to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a torque testing device for a magnetic coupling, comprising a base and a magnetic coupling. Mounting brackets are symmetrically fixed to the base, and supporting slide rods are symmetrically fixed between the mounting brackets. A sliding adjustment seat is provided above the base, and symmetrically spaced limit sliding holes are formed within the sliding adjustment seat. The limit sliding holes slide in cooperation with the supporting slide rods. An adjusting worm gear is rotatably mounted on the sliding adjustment seat, and a mounting frame is fixed to the adjusting worm gear. A limit sliding groove is formed within the mounting frame, and a limit slider is slidably mounted within the limit sliding groove. A connecting shaft is rotatably mounted within the limit slider. A second connecting flange is fixed to one end of the connecting shaft, and a static torque sensor is fixed to the other end of the connecting shaft. A fixed bracket is fixed to the base, and a transmission shaft is rotatably mounted within the fixed bracket. A first connecting flange is fixed to one end of the transmission shaft. A heating mechanism is fixed to the base for heating the magnetic coupling.

[0006] Preferably, an interactive panel is fixedly connected to the front of the base, a first threaded adjusting screw is rotatably installed between the two mounting brackets, and a first threaded sleeve is embedded in the sliding adjusting seat, the first threaded sleeve being threadedly engaged with the first threaded adjusting screw.

[0007] Preferably, bearing seats are symmetrically fixed to the sliding adjustment seat, and an adjusting worm is rotatably installed between the bearing seats, the adjusting worm meshing with the adjusting worm wheel.

[0008] Preferably, a second adjusting screw is rotatably installed in the limiting slide groove, and a second threaded sleeve is embedded in the limiting slider, with the second adjusting screw and the second threaded sleeve threadedly engaged.

[0009] Preferably, a power motor is fixedly connected to the base, and a drive wheel is fixedly connected to the output end of the power motor.

[0010] Preferably, a driven wheel is fixedly connected to the other end of the drive shaft, and a drive belt connects the driven wheel and the driving wheel.

[0011] Preferably, the heating mechanism includes a support frame and a heating wire, with a fan duct fixedly connected to the support frame and the heating wire fixedly connected inside the fan duct.

[0012] Preferably, a motor bracket is fixedly connected inside the air duct, a fan is fixedly connected to the front of the motor bracket, and blades are fixedly connected to the output end of the fan.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By rotating the adjusting worm, the adjusting worm wheel can be driven to rotate, thereby changing the docking angle of the two magnetic couplings. This allows for an experiment on the torque transmission changes under the offset state of the magnetic coupling installation angle, simulating the torque transmission efficiency of the magnetic coupling under eccentric conditions.

[0014] 2. By rotating the adjusting worm, the adjusting worm wheel can be driven to rotate, thereby changing the mating angle of the two magnetic couplings. This allows for experiments on the torque transmission changes under the offset state of the magnetic coupling installation angle, simulating the torque transmission efficiency under the misaligned state of the magnetic coupling.

[0015] 3. Starting the fan can drive the blades to rotate. The rotation of the blades can draw air into the air duct and then discharge it from the end. After passing through the heating wire, the air will be heated. The heated air will blow towards the magnetic coupling, thereby heating the magnetic coupling and simulating the transmission torque of the magnetic coupling under high temperature environment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0020] Example 1 A torque testing device for a magnetic coupling includes a base 1 and a magnetic coupling 9. Mounting brackets 102 are symmetrically fixed to the base 1, and supporting slide rods 104 are symmetrically fixed between the mounting brackets 102. A sliding adjustment seat 4 is provided above the base 1, and symmetrically formed limiting sliding holes 402 are provided inside the sliding adjustment seat 4. The limiting sliding holes 402 are slidably engaged with the supporting slide rods 104. An adjusting worm gear 5 is rotatably mounted on the sliding adjustment seat 4, and a mounting bracket 501 is fixedly connected to the adjusting worm gear 5. A limiting groove 502 is provided inside the frame 501. A limiting slider 6 is slidably installed in the limiting groove 502. A connecting shaft is rotatably installed in the limiting slider 6. A second connecting flange 602 is fixedly connected to one end of the connecting shaft, and a static torque sensor 603 is fixedly connected to the other end of the connecting shaft. A fixed bracket 2 is fixedly connected to the base 1. A drive shaft is rotatably installed in the fixed bracket 2. A first connecting flange 201 is fixedly connected to one end of the drive shaft. A heating mechanism is fixedly connected to the base 1. The heating mechanism is used to heat the magnetic coupling 9.

[0021] In this embodiment, the magnetic coupling 9 can be fixedly installed on the device by bolts connecting the first connecting flange 201 and the second connecting flange 602. The first connecting flange 201 is driven to rotate by a power mechanism, which in turn drives the magnetic coupling 9 to rotate. The magnetic coupling 9 transmits power to the second connecting flange 602. The second connecting flange 602 is fixedly connected to a static torque sensor 603 via a connecting shaft. The static torque sensor 603 can detect the static torque and the maximum torque transmitted by the magnetic coupling 9. The limiting sliding hole 402 slides with the support sliding rod 104, allowing the sliding adjustment seat 4 to be slidably installed on the base 1. The position of the sliding adjustment seat 4 can be adjusted left and right by adjusting the worm gear 5 to move the limiting slider 6. The limit slider 6 can move the second connecting flange 602, thereby adjusting the distance between the magnetic couplings 9. This allows for testing the torque transmission changes of the magnetic couplings 9 under different distances. The limit slider 6 is slidably installed inside the limit groove 502. Entering the limit slider 6 allows it to move up and down, moving one end of the magnetic coupling 9 and causing the two magnetic couplings 9 to be misaligned. This allows for testing the transmission torque of the magnetic couplings 9 in the misaligned state. The adjusting worm gear 5 is rotated and installed on the sliding adjusting seat 4. Adjusting the worm gear 5 can drive the limit slider 6 to rotate at a certain angle, thereby testing the transmission torque of the magnetic couplings 9 in the offset state. The support frame 7 can be used to heat the magnetic couplings 9, allowing for testing whether the transmission torque of the magnetic couplings 9 changes under high temperature conditions.

[0022] Example 2 An interactive panel 101 is fixedly connected to the front of the base 1. A first threaded adjusting screw 103 is rotatably installed between two mounting brackets 102. A first threaded sleeve 401 is embedded in the sliding adjusting seat 4. The first threaded sleeve 401 is threadedly engaged with the first threaded adjusting screw 103. Bearing seats are symmetrically fixedly connected to the top of the sliding adjusting seat 4. An adjusting worm 403 is rotatably installed between the bearing seats. The adjusting worm 403 meshes with the adjusting worm wheel 5. A second adjusting screw 503 is rotatably installed in the limiting slide groove 502. A second threaded sleeve 601 is embedded in the limiting slider 6. The second adjusting screw 503 is threadedly engaged with the second threaded sleeve 601.

[0023] In this embodiment, the first threaded adjusting screw 103 is threadedly engaged with the first threaded sleeve 401. Rotating the first threaded adjusting screw 103 can drive the fixed bracket 2 to move, thereby adjusting the position of the fixed bracket 2 left and right, and thus adjusting the distance between the magnetic couplings 9. The adjusting worm 403 is meshed with the adjusting worm wheel 5. Rotating the adjusting worm 403 can drive the adjusting worm wheel 5 to rotate, thus changing the mating angle of the two magnetic couplings 9. The second adjusting screw 503 is threadedly engaged with the second threaded sleeve 601. Rotating the second adjusting screw 503 can drive the limiting slider 6 to move, thus adjusting the two magnetic couplings 9 to be staggered.

[0024] Example 3 A power motor 3 is fixedly connected to the base 1. A drive wheel 301 is fixedly connected to the output end of the power motor 3. A driven wheel 202 is fixedly connected to the other end of the transmission shaft. A transmission belt 302 connects the driven wheel 202 and the drive wheel 301.

[0025] In this embodiment, starting the power motor 3 can drive the drive wheel 301 to rotate. The drive wheel 301 and the driven wheel 202 are driven by the transmission belt 302. Thus, the rotation of the drive wheel 301 can drive the driven wheel 202 to rotate through the transmission belt 302, and the rotation of the driven wheel 202 can drive the first connecting flange 201 to rotate.

[0026] Example 4 The heating mechanism includes a support frame 7 and a heating wire 705. A fan 701 is fixedly connected to the support frame 7. The heating wire 705 is fixedly connected inside the fan 701. A motor bracket 702 is fixedly connected inside the fan 701. A fan 703 is fixedly connected to the front of the motor bracket 702. A blade 704 is fixedly connected to the output end of the fan 703.

[0027] In this embodiment, starting the fan 703 can drive the blades 704 to rotate. The rotation of the blades 704 can draw air into the air duct 701 and then discharge it from the end. After passing through the heating wire 705, the air will be heated. The heated air will be blown towards the magnetic coupling 9, thereby heating the magnetic coupling 9 and simulating the transmission torque of the magnetic coupling 9 under high temperature environment.

[0028] The working principle and usage of this invention are as follows: The magnetic coupling 9 can be fixedly installed on the device by bolts connecting the first connecting flange 201 and the second connecting flange 602. Starting the power motor 3 drives the first connecting flange 201 to rotate, which in turn drives the magnetic coupling 9 to rotate. Power is transmitted to the second connecting flange 602 via the magnetic coupling 9. The second connecting flange 602 is fixedly connected to a static torque sensor 603 via a connecting shaft. The static torque sensor 603 can detect the static torque and the maximum torque transmitted by the magnetic coupling 9. Rotating the first threaded adjusting screw 103 moves the fixed bracket 2, thereby adjusting the magnetic coupling. The spacing between the two magnetic couplings 9 can be used to test the torque transmission changes of the magnetic couplings 9 under different spacings. Rotating the adjusting worm 403 can drive the adjusting worm wheel 5 to rotate, thus changing the mating angle of the two magnetic couplings 9, and then testing the torque transmission changes of the magnetic couplings 9 in the offset installation angle state. Rotating the second adjusting screw 503 can drive the limit slider 6 to move, adjusting the two magnetic couplings 9 to be offset from each other, and then testing the torque transmission changes of the magnetic couplings 9 in the offset state. Using the fan 703 and heating wire 705, heated air can be blown towards the magnetic couplings 9, thus heating the magnetic couplings 9 and simulating the transmission torque of the magnetic couplings 9 under high temperature environment.
