Description

Technical Field

[0001] The present invention belongs to the field of performance tests, and particularly relates to a performance test device for magnetic drive components. Background Art

[0002] Magnetic drive components are devices that transmit power through magnetic force and are commonly used in mechanical systems. These components utilize the attraction or repulsion of magnetic fields to transmit rotational or linear power without direct physical contact. This technology has advantages in certain specific applications, such as reducing wear, improving efficiency, and reducing maintenance requirements.

[0003] Typical examples of magnetic drive components include magnetic couplings and magnetic drive shaft couplings. Magnetic couplings transmit torque through the action of magnetic fields and are commonly used in applications that require isolation and protection of the driving end and the passive end. Magnetic drive shaft couplings can achieve non-contact transmission between two shafts and are commonly found in systems that need to eliminate mechanical vibrations or bearing overloads.

[0004] Generally speaking, magnetic drive components represent a part of innovation and diversity in modern engineering technology, especially having potential in applications that require high efficiency, low friction, and low maintenance.

[0005] Existing as disclosed in CN110849621A, there is a performance test device for magnetic drive components, which includes a driving motor, an axial force test component, a conductive slip ring, a temperature measuring sensor, a transmission shaft component, a loading motor, a driving end equipment support platform, a load end equipment support platform, adjustment pad Ⅰ, adjustment pad Ⅱ, two torque meters, two pads, and multiple flexible couplings; the driving motor is connected to one end of a torque meter through a flexible coupling, the other end of the torque meter is connected to one end of the axial force test component through a flexible coupling, and the other end of the axial force test component is fixedly connected to the conductor disk of the magnetic drive component of the magnetic drive component through a flexible coupling.

[0006] The existing performance test device for magnetic drive components still has the following deficiencies:

[0007] 1. During the transmission process of magnetic drive components, they mainly rely on the attraction and repulsion forces between magnetic poles. However, if there is interference from an external magnetic field, it may greatly affect the stability and transmission rate of magnetic drive components. But the existing test devices do not have components that can target the influence of the magnetic field.

[0008] 2. Due to their unique characteristics, magnetic drive components are easily applied to various scenarios. However, when the object or device is in a moving state, whether the transmission effect of the magnetic drive components will be affected by the externally applied force.

[0009] 3. When the electromagnetic field intensities of the same magnitude are at different positions of the magnetic drive components, different magnetic field directions will be generated, which will easily have different degrees of influence on this. The existing devices cannot change the magnetic field direction to detect the magnetic drive components. Summary of the Invention

[0010] The object of the present invention is to solve the problems in the above-mentioned background technology that if there is interference from an external magnetic field, it may greatly affect the stability and transmission speed of the magnetic drive components. Magnetic fields of the same magnitude but different directions are also likely to affect the magnetic drive components, applying an external force, and thus affecting the transmission effect of the magnetic drive components. The present invention provides a performance test device for magnetic drive components.

[0011] To achieve the above object, the present invention adopts the following technical solutions: A performance test device for magnetic drive components, including a base, a bracket is fixedly connected to the side surface of the base, a magnetic drive assembly is arranged on the upper surface of the base, drive assemblies are arranged on both sides of the base, an electromagnetic structure is arranged between the drive assemblies. The magnetic drive assembly includes an outer rotor, a central rotor, and an inner rotor. The outer rotor and the central rotor are both arranged in a ring shape. The outer rotor, the central rotor, and the inner rotor are arranged inward in sequence. A distance of 0.5 cm is left between the outer rotor, the central rotor, and the inner rotor.

[0012] Furthermore, a rotating structure is arranged below the base. The rotating structure includes a bottom plate. A turntable is rotatably connected to the upper surface of the bottom plate. The base and the bracket are both fixedly connected to the upper surface of the turntable.

[0013] Furthermore, the outer rotor is fixedly connected to the upper surface of the base. A plurality of first magnets are snap-connected to the side surface of the outer rotor in a circumferential array. A plurality of iron core rods are penetrated and fixedly connected to the side surface of the central rotor in a circumferential array. A plurality of second magnets are snap-connected to the side surface of the inner rotor in a circumferential array.

[0014] Furthermore, rotating shafts are fixedly connected to both side surfaces of the inner rotor. The rotating shafts are arranged inside the second magnets. The rotating shafts penetrate and are rotatably connected to side plates. The side plates are fixedly connected to the side surface of the outer rotor through connecting columns. A detector is fixedly connected to the outer side surface of the side plates. The rotating shafts are electrically connected to the detector.

[0015] Furthermore, the drive assembly includes a chute. A reciprocating lead screw is rotatably connected to the inner side surface of the chute. A motor is fixedly connected to the outer side surface of the chute. The output end of the motor penetrates the chute and is fixedly connected to one end of the reciprocating lead screw.

[0016] Furthermore, the electromagnetic structure includes an inner core, which is arranged in a 3 / 4 ring shape, and a surrounding cable is fixedly connected to the outer side of the inner core. The lower surfaces of both ends of the inner core are fixedly connected to bottom blocks, and the bottom block is slidably connected in the slide groove, and the reciprocating screw rod passes through and is threadedly connected in the bottom block.

[0017] Furthermore, two electric slide rails are fixedly connected to the upper surface of the slide groove, and the two electric slide rails are arranged on both sides of the reciprocating screw rod.

[0019] Compared with the existing technology, the advantages of this magnetic transmission component performance test device are:

[0020] 1. The present invention arranges an electromagnetic structure on the outside of the magnetic transmission component. When testing the performance of the magnetic transmission component, the surrounding cable can be charged, so that the surrounding cable will generate an electromagnetic field.

Specific embodiments

[0029] The following embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention.

[0030] As Figures 1 - 5 shown, a performance test device for a magnetic drive component includes a base 1. A bracket 2 is fixedly connected to the side surface of the base 1. A magnetic drive assembly is arranged on the upper surface of the base 1. Transmission components are arranged on both sides of the base 1. An electromagnetic structure is arranged between the transmission components. The magnetic drive assembly includes an outer rotor 3, a central rotor 5, and an inner rotor 7. Both the outer rotor 3 and the central rotor 5 are arranged in a ring shape. The outer rotor 3, the central rotor 5, and the inner rotor 7 are arranged inward in sequence. A distance of 0.5 cm is left between the outer rotor 3, the central rotor 5, and the inner rotor 7;

[0031] A rotating structure is arranged below the base 1. The rotating structure includes a bottom plate 23. A turntable 25 is rotatably connected to the upper surface of the bottom plate 23. The base 1 and the bracket 2 are both fixedly connected to the upper surface of the turntable 25. By arranging the rotating structure below the magnetic drive component, during the normal operation of the magnetic drive component, only by rotating the turntable 25, the rotation of the magnetic drive component can be realized. Furthermore, the magnetic drive component will be subjected to an axial force, thereby increasing the detection surface of the device;

[0032] The outer rotor 3 is fixedly connected to the upper surface of the base 1, and the side of the outer rotor 3 is connected with a plurality of No. 1 magnets 4 in an annular array, and the side of the center rotor 5 is penetrated and fixedly connected with a plurality of iron core rods 6 in an annular array, and the side of the inner rotor 7 is connected with a plurality of No. 2 magnets 8 in an annular array. The No. 1 magnets 4 on the side of the outer rotor 3 and the No. 2 magnets 8 on the side of the inner rotor are arranged alternately with anodes and cathodes. Since the center rotor 5 is non-magnetic, the magnetic relationship between the outer rotor 3 and the inner rotor 7 will be stirred under the rotation of the center rotor 5, and the outer rotor 3 is fixed above the base 1, which will cause the inner rotor 7 to rotate;

[0033] The two sides of the inner rotor 7 are fixedly connected with a rotating shaft 9, which is arranged in the second magnet 8. The rotating shaft 9 penetrates and is rotatably connected with a side plate 10, which is fixedly connected to the side of the outer rotor 3 through a connecting column. The outer side of the side plate 10 is fixedly connected with a detector 11, and the rotating shaft 9 is electrically connected to the detector 11. When a magnetic pole effect is generated between the outer rotor 3 and the inner rotor 7, the rotating shaft 9 rotates in the side plate 10. At the same time, the side plate 10 can also play a further limiting role on the central rotor 5 and the inner rotor 7.

[0034] The transmission assembly includes a slide slot 12, the inner side of the slide slot 12 is rotatably connected to a reciprocating screw rod 14, the outer side of the slide slot 12 is fixedly connected to a motor 13, and the output end of the motor 13 passes through the slide slot 12 and is fixedly connected to one end of the reciprocating screw rod 14;

[0035] The electromagnetic structure includes an inner core 15, which is set to a 3 / 4 ring shape. The outer side of the inner core 15 is fixedly connected with a surrounding cable 16. The lower surfaces of both ends of the inner core 15 are fixedly connected with bottom blocks 17. The bottom block 17 is slidably connected in the slide groove 12. The reciprocating screw rod 14 passes through and is threadedly connected in the bottom block 17. By setting the electromagnetic structure on the outer side of the magnetic transmission component, the surrounding cable 16 can be charged when the performance of the magnetic transmission component is tested, so that the surrounding cable 16 will generate an electromagnetic field. After the central rotor 5 is turned, due to the interaction between the magnets between the external rotor 3 and the internal rotor 7, the internal rotor 7 will rotate. The measurement result can be obtained from the detector 11. Under the interference of the external electromagnetic field, the stability performance between the magnetic transmission components can also be obtained from the monitoring results, thereby improving the detection function of the device;

[0036] The upper surface of the sliding groove 12 is fixedly connected with two electric slide rails 18. The two electric slide rails 18 are arranged on both sides of the reciprocating lead screw 14. The lower end of the surrounding cable 16 is fixedly connected with a connection terminal 19 through an electric connecting rod 20. The connection terminal 19 is snap-connected in the electric slide rail 18. By arranging the transmission assembly below the electromagnetic structure, the reciprocating displacement of the electromagnetic structure can be realized. During the reciprocating displacement process, the electromagnetic structure relies on the electric slide rail 18 and the power structure to keep the surrounding cable always energized during the movement, that is, the detection intensity of the influence of the device on the external magnetic field can be enhanced by changing the influence of the magnetic fields in different directions on the magnetic force transmission components;

[0037] A power structure is arranged between the two groups of transmission assemblies. The power structure includes a power supply box 21. The power supply box 21 is arranged between the two groups of transmission assemblies. Both ends of the power supply box 21 are electrically connected with connection cables 22. The ends of the connection cables 22 are electrically connected to the side surfaces of the electric slide rails 18. The power supply box 21 transmits the power from the connection cables 22 to the electric slide rails 18, and then transmits the power to the surrounding cable 16 through the connection terminal 19 and the electric connecting rod 20, so as to generate an electromagnetic field to conduct tests on the magnetic force transmission components. Finally, the power flows back into the power supply box 21 from the other end of the surrounding cable 16. And the power supply box 21 can have the function of adjusting the voltage magnitude, so as to increase the control group of the performance test to ensure that the test results are more accurate.

[0038] The working principle of the present invention is as follows:

[0039] The first magnets 4 on the side surface of the outer rotor 3 and the second magnets 8 on the side surface of the inner rotor are both arranged with the anodes and cathodes staggered with each other. Since the central rotor 5 has no magnetism, under the rotation action of the central rotor 5, the magnetic force relationship between the outer rotor 3 and the inner rotor 7 will be stirred. And the outer rotor 3 is fixed above the base 1, so that the inner rotor 7 will rotate. When the inner rotor 7 starts to rotate, the detector 11 can analyze the rotation speed of the rotating shaft 9, and then obtain the result of the magnetic force transmission;

[0040] By arranging the electromagnetic structure outside the magnetic force transmission components, when conducting performance tests on the magnetic force transmission components, the surrounding cable 16 can be charged, so that the surrounding cable 16 will generate an electromagnetic field. Under the interference of the externally applied electromagnetic field, the stability of the magnetic force transmission components can also be known from the monitoring results, thereby improving the detection function of the device;

[0041] By arranging the rotating structure below the magnetic force transmission components, during the normal operation of the magnetic force transmission components, only by rotating the turntable 25, the rotation of the magnetic force transmission components can be realized. Then the magnetic force transmission components will be subjected to an axial force, thereby increasing the detection surface of the device;

[0042] By arranging the transmission component below the electromagnetic structure, the reciprocating displacement of the electromagnetic structure can be realized. During the reciprocating displacement process, the electromagnetic structure relies on the electric slide rail 18 and the power structure to keep the surrounding cable always energized during the movement. During the reciprocating displacement process of the electromagnetic structure, the magnetic field force and direction generated by the magnetic force transmission component will also change in real time. That is, by changing the influence of the magnetic field in different directions on the magnetic force transmission component, the detection intensity of the device on the external magnetic field influence can be enhanced.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
