Description

Technical Field

[0001] The invention relates to the technical field of magnetic wheel speed regulators, and in particular to a mobile base type magnetic wheel speed regulator. Background Art

[0002] Magnetic wheel speed regulator, also known as permanent magnet speed regulator, is a device that uses the interaction between the magnetic field generated by permanent magnets and the current to achieve motor speed control. The mobile base type magnetic wheel speed regulator adjusts the relative position of the permanent magnet rotor and the conductor rotor in the axial direction to change the torque transmitted between the two, thereby achieving repeatable, adjustable and controllable output torque and speed, and achieving the purpose of speed regulation and energy saving.

[0003] In the prior art, according to the patent application number: CN202310950418.8, the motor movable base type permanent magnet speed regulator, the application uses the action of the hydraulic push rod to lift the motor fixing plate and the lifting plate to a certain height, so as to achieve the purpose of transmission speed regulation of load equipment at different heights. However, in the process of adjusting the height of a large motor, due to the large weight of the motor itself, and the fixed plate responsible for the motor assembly, there is an electric drive mechanism for adjusting the relative position of the permanent magnet rotor and the conductor rotor in the axial direction, resulting in a large load on the hydraulic push rod. Even if the positioning nails are tightened by bolts, it is difficult to ensure that the motor is stable at a certain height for a long time and the speed of the equipment is regulated.

[0004] Moreover, when the motor is running, the bottom of the fixed plate is in a suspended state. The vibration problem during the operation of the motor will further affect its stable state when it is installed and used. When the motor is suspended for a long time, it is easy for the conductor rotor and the permanent magnet rotor to be misaligned. The vibration and axial force changes caused by the misalignment will affect the stability of the magnetic coupling during operation, especially in the case of continuous speed regulation. The actuator used to adjust the meshing length will be subjected to alternating loads, which will affect the accuracy of the speed regulation of the magnetic coupling.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 6 The present invention provides a technical solution: a mobile base type magnetic wheel speed regulator, including a pedestal 1, a driving motor 4 and a magnetic wheel transmission mechanism, a roller 2 is installed on the pedestal 1, a sliding frame 3 is placed on the roller 2, a driving motor 4 is installed on the sliding frame 3, a first vertical frame 19 is fixedly provided on the sliding frame 3, a second vertical frame 29 is fixedly provided on the pedestal 1, a magnetic wheel transmission mechanism is arranged between the first vertical frame 19 and the second vertical frame 29, a lifting member for adjusting the height of the magnetic wheel transmission mechanism is arranged on the pedestal 1, a transmission member is arranged on the first vertical frame 19, and the driving motor 4 acts on the magnetic wheel transmission mechanism through the transmission member.

[0031] During use, when facing the transmission output of equipment at different heights, it is only necessary to adjust the magnetic wheel transmission mechanism to a certain height through the lifting piece, without the need to synchronously lift the drive motor 4 and the sliding frame 3 responsible for carrying the drive motor 4, thereby reducing the load weight of the lifting piece and ensuring that it can achieve long-term and stable support for the relatively light magnetic wheel transmission mechanism. During the operation of the drive motor 4, since the bottom of the sliding frame 3 can be stably supported, the motor vibration can be effectively avoided, which affects the overall stability of the equipment, thereby ensuring the accuracy of the speed regulation of the magnetic coupling.

[0032] By setting the transmission member, the drive motor 4 can drive the height-adjustable magnetic wheel transmission mechanism without changing its height, thereby ensuring that the drive motor 4 always works in a safe and stable installation state.

[0033] A square frame 12 is fixedly provided on the pedestal 1, and an equipment frame 16 is fixedly provided on the side end of the square frame 12. A pneumatic rod 18 for controlling the movement of the sliding frame 3 is installed on the equipment frame 16. A supporting frame 5 slides vertically in the square frame 12, and a groove 501 is formed inside the supporting frame 5. A pressure plate 7 is movably provided in the groove 501. A bending frame 35 is fixedly provided at the bottom of the sliding frame 3. Two slides 9 and a driving member for driving the two slides 9 to move are provided in the square frame 12. A compression structure and a parallel linkage are also provided in the square frame 12. When the two slides 9 move in opposite directions, the supporting frame 5 is first lifted up and contacts with the bottom of the sliding frame 3 under the action of the compression structure, and then the pressure plate 7 presses the bending frame 35 under the action of the parallel linkage.

[0034] When the conductor wheel 26 and the permanent magnet wheel 27 move relative to each other, the conductor wheel 26 cuts the magnetic lines of force, generates an induced current in the conductor wheel 26, and then generates an induced magnetic field. The induced magnetic field interacts with the magnetic field generated by the permanent magnet wheel 27 to generate magnetic force, thereby realizing the transmission of torque.

[0035] The pneumatic rod 18 controls the sliding frame 3 to drive the driving motor 4 to move in the horizontal direction, adjusts the relative position of the permanent magnet wheel 27 and the conductor wheel 26 in the axial direction, changes the meshing area between the two, realizes the change of the size of the transmitted torque, and then adjusts the load speed.

[0036] Before the speed adjustment is required, the two slide plates 9 are controlled to move synchronously in opposite directions by the driving member, so that the pressure plate 7 is first lifted upward from the bending frame 35 under the action of the parallel linkage, and the pressing state of the bending frame 35 is released. Then, the support frame 5 is separated downward from the bottom of the sliding frame 3 under the action of the pressing member. At this time, the sliding frame 3 is driven to move along the roller 2 by the extension and contraction of the free end of the pneumatic rod 18 to adjust the relative position of the permanent magnetic wheel 27 and the conductor wheel 26. During the adjustment process, since the sliding frame 3 moves along the roller 2, the friction resistance of the sliding frame 3 with a heavy load is reduced. The position of the sliding frame 3 can be easily adjusted by the pneumatic rod 18 with a relatively small power, and the wear on the bottom of the sliding frame 3 is reduced, thereby further ensuring the accuracy of the speed adjustment of the magnetic wheel speed regulator.

[0037] After completing the speed adjustment, the two slides 9 are controlled by the driving member to move synchronously in opposite directions, so that the supporting frame 5 first contacts the bottom of the sliding frame 3 upwards, and then the pressure plate 7 presses the bending frame 35 downwards, while ensuring stable support for the bottom of the sliding frame 3, increasing the contact friction with the sliding frame 3 to avoid vibration during the operation of the driving motor 4, affecting the stable placement of the sliding frame 3, thereby maintaining a stable positional relationship between the sliding frame 3 and the base 1.

[0038] Specifically, Figure 1 and Figure 2 As shown, the magnetic wheel transmission mechanism includes a conductor wheel 26 and a permanent magnet wheel 27. The conductor wheel 26 is coaxially fixed with a rotating shaft 25 that slides through the first frame 19, and the permanent magnet wheel 27 is fixed with a load shaft 28 that slides through the second frame 29. Slide blocks 30 are vertically slidable in the first frame 19 and the second frame 29, and a bearing sleeve 31 is fixed in the slide block 30.

[0039] The bearing sleeve 31 provides a fixed position for the rotating shaft 25 and the load shaft 28 to prevent the shafts from displacement or vibration during operation. At the same time, the bearing sleeve 31 can be used to reduce friction and wear of the shafts.

[0040] The conductor wheel 26 is made of conductive material, such as copper or aluminum, and the permanent magnet wheel 27 is made of permanent magnets, usually materials with high magnetic energy product and stable magnetic field characteristics, such as rare earth permanent magnet materials such as neodymium iron boron. In the magnetic wheel speed regulator, the conductor wheel 26 and the permanent magnet wheel 27 are placed opposite to each other, and there is a certain air gap between them. When the conductor wheel 26 rotates, it and the permanent magnet wheel 27 produce relative motion, and the magnetic field generated by the permanent magnet wheel 27 induces eddy currents in the conductor wheel 26. These eddy currents in turn generate an induced magnetic field, which interacts with the magnetic field of the permanent magnet wheel 27, thereby driving the permanent magnet wheel 27 to rotate in the same direction to achieve torque transmission.

[0041] The lifting member includes a protective frame 32 sleeved on the outside of the conductor wheel 26 and the permanent magnet wheel 27, and a bracket 33 corresponding to the two bearing sleeves 31 is fixed on the protective frame 32. The bracket 33 close to the first vertical frame 19 is slidably connected to the bearing sleeve 31, and the bracket 33 close to the second vertical frame 29 is fixedly connected to the bearing sleeve 31. A hydraulic rod 34 is installed on the base 1, and an arc-shaped support plate that acts as the protective frame 32 is fixed at the output end of the hydraulic rod 34.

[0042] The protection frame 32 can protect the magnetic wheel transmission mechanism from damage and avoid equipment failure caused by heavy object impact, scratches and other human or accidental factors. At the same time, heat dissipation holes are formed in the protection cover to ensure the normal operation of the speed regulator. The protection frame 32 is driven to move in the vertical direction through the bracket 33 under the action of the arc-shaped support plate by the extension and contraction of the hydraulic rod 34.

[0043] Specifically, Figure 1 and Figure 2 As shown, the transmission member includes four wheel discs 22 and a component that drives the four wheel discs 22 to rotate synchronously, wherein one wheel disc 22 is rotationally connected to the first stand 19, and the other three wheel discs 22 are movably arranged on the outside of the first stand 19, and connecting rods 24 are rotationally connected between the four wheel discs 22, and the four connecting rods 24 form a diamond structure.

[0044] The wheel 22 is a toothed plate that meshes with the chain 23. When the magnetic wheel transmission mechanism moves in the vertical direction, one of the wheel discs 22 will be driven to move synchronously through the rotating shaft 25. During the movement of the wheel disc 22, the other two wheel discs 22 distributed at the same level will be pulled to move in a circular direction through the connecting rod 24. Under the restraint of the connecting rod 24, the four wheel discs 22 always keep the chain 23 in a tight state, thereby realizing the drive motor 4 to transmit the magnetic wheel transmission mechanism that can be adjusted in height.

[0045] In actual use, the transmission member is not only connected to the output shaft of the drive motor 4 , but can also be connected to the load shaft 28 in the same manner as required, thereby further increasing the transmission range of the drive motor 4 .

[0046] The component that drives the four wheel discs 22 to rotate synchronously includes a chain 23 meshingly mounted on the outside of the four wheel discs 22. The outside of the first stand 19 is rotatably connected to a first gear 20 and a second gear 21. The first gear 20 is coaxially fixed to the driving motor 4, and the second gear 21 is coaxially fixed to the wheel disc 22.

[0047] The first gear 20 is controlled to rotate by the driving motor 4 , so that the second gear 21 meshing with the first gear 20 drives the wheel disc 22 to rotate, and the four wheel discs 22 rotate synchronously under the action of the chain 23 .

[0048] Specifically, Figure 3 and Figure 5 As shown, the driving member includes a bidirectional screw 13 rotatably connected in a square frame 12, and the bidirectional screw 13 is screwed and connected with two slides 9, and a servo motor 17 for controlling the rotation of the bidirectional screw 13 is installed on the equipment frame 16;

[0049] The servo motor 17 is started to control the rotation of the bidirectional screw 13, so that the slide plate 9 screwed with the bidirectional screw 13 moves horizontally synchronously. The servo motor 17 is a prior art, which is a micro motor used as an actuator in an automatic control system. It can control the speed and position of the motor according to the input control signal to achieve precise control.

[0050] Specifically, Figure 3-Figure 6 As shown, the compression structure includes a round block 901 fixedly mounted on the side end of the slide plate 9, a frame plate 14 is fixedly mounted on the bottom of the support frame 5, a slideway 15 is formed inside the frame plate 14 for cooperating with the sliding of the round block 901, and the slideway 15 is composed of a transverse groove and an oblique groove; the parallel linkage includes an axle rod 8 rotatably connected in the groove 501 and four parallel distributed arms 6, and a component for driving the axle rod 8 to rotate, the axle rod 8 is coaxially fixed with two of the arms 6, and the free end of the arm 6 is rotatably connected to the pressure plate 7.

[0051] When the round block 901 moves along the horizontal groove of the slide 15 along with the movement of the slide 9, the height of the support frame 5 remains unchanged. When the round block 901 moves along the oblique groove of the slide 15 along with the movement of the slide 9, the support frame 5 fixed to the frame plate 14 is driven to move in the vertical direction through the pressure transmission of the side wall of the round block 901 on the inner wall of the oblique groove.

[0052] The component that drives the shaft 8 to rotate includes a sleeve 10 that is slidably mounted on the outside of the shaft 8, and the sleeve 10 is fixed to the slide plate 9. A protrusion 11 is formed on the inner wall of the sleeve 10, and a slide rail 801 that slides in cooperation with the protrusion 11 is formed on the side wall of the shaft 8. The slide rail 801 is composed of a linear groove and a spiral groove.

[0053] When the sleeve 10 slides along the outer side of the shaft rod 8, the protrusion 11 fixed on the inner wall of the sleeve 10 slides along the slide rail 801. When the protrusion 11 slides along the linear groove of the slide rail 801, the round block 901 slides along the oblique groove of the slideway 15. At this time, the shaft rod 8 is stationary relative to the support frame 5. When the protrusion 11 slides along the spiral groove of the slide rail 801, the round block 901 slides along the transverse groove of the slideway 15. The protrusion 11 compresses the inner wall of the spiral groove, driving the support arm 6 fixed to the shaft rod 8 to rotate. The support arm 6 constituting the parallel connecting rod pulls the pressure plate 7, so that the bottom of the pressure plate 7 maintains a horizontal state and abuts against or separates from the bending frame 35.

[0054] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
