Description

Technical Field

[0001] This utility model specifically relates to a cylindrical maintenance-free permanent magnet speed regulator with a movable base. Background Technology

[0002] A permanent magnet speed controller, also known as a wound permanent magnet coupling drive, is a transmission device that transmits torque through an air gap. The working principle of a permanent magnet speed controller is based on the principle of magnetic drive. When the motor drives the conductor rotor to rotate, the conductor disk cuts the magnetic lines of force of the permanent magnet in the permanent magnet rotor, thereby generating eddy currents on the conductor surface and forming an induced magnetic field. According to the principle of attraction between opposite poles and repulsion between like poles, adjacent induced magnetic fields generate coupling forces on the permanent magnet, i.e., attraction and repulsion. These two forces are superimposed in the direction of rotation, thereby driving the permanent magnet rotor to rotate in the same direction as the conductor rotor. Ultimately, torque is generated on the output shaft on the load side, driving the load to rotate. By adjusting the air gap between the permanent magnet and the conductor, the transmitted torque can be controlled, thus achieving the adjustment of the load speed.

[0003] Permanent magnet speed controllers can achieve repeatable, adjustable, and controllable output torque and speed, and have advantages such as energy saving, noise reduction, and stability. They are also simple in structure, reliable in operation, and energy-saving and consumption-reducing, so they are widely used in modern industry.

[0004] When using a permanent magnet speed controller, maintenance is required, especially in complex and harsh working environments, such as mines or other dusty environments. In dusty environments, dust accumulation can lead to a decline in the performance and lifespan of the permanent magnet speed controller. At the same time, dust entering the distance adjustment mechanism inside the permanent magnet speed controller can cause inaccurate torque adjustment, affecting its use. Therefore, in order to improve its service life, the current permanent magnet speed controller needs to be maintained frequently, which is costly and troublesome. Therefore, there is a need for a permanent magnet speed controller that avoids frequent maintenance. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing permanent magnet speed controllers mentioned in the background art require frequent maintenance in complex environments, which is inconvenient and costly.

[0006] To address the aforementioned technical problems, a cylindrical maintenance-free permanent magnet speed controller with a movable base is proposed. This is achieved through the following technical solution: A cylindrical maintenance-free permanent magnet speed controller with a movable base includes a motor and a permanent magnet speed controller. The permanent magnet rotor within the speed controller is connected to the load, and the conductor rotor is connected to the motor. The motor drives the load through the permanent magnet speed controller. The controller is characterized by further including a mounting section and a speed controller protection section. The motor is mounted on a mounting surface via a fixed base on the mounting section. The speed controller protection section is mounted on the mounting surface and movably installed outside the permanent magnet speed controller. The speed controller protection section protects and dissipates heat from the permanent magnet speed controller, avoiding frequent maintenance and improving the service life of the permanent magnet speed controller in harsh environments.

[0007] In a preferred embodiment of the present invention, the installation unit includes a moving component, a height adjustment component, a drive component, and a dustproof component. The moving component is connected to a motor, and the motor's output torque is controllably adjustable under the action of the moving component. The height adjustment component is mounted on a fixed base and controllably adjusts the installation height of the motor. The drive component is connected to the moving component via a lead screw, providing power for the movement of the moving component. The dustproof component is mounted on the moving component to prevent dust and debris from falling into the moving component, ensuring stable operation of the moving component in harsh environments. The dustproof component also helps to block falling dust when adjusting the distance between the permanent magnet rotor and the conductor rotor of the permanent magnet speed controller, preventing dust from entering the moving component and ensuring the accuracy of the torque adjustment of the permanent magnet speed controller.

[0008] In a preferred embodiment of the present invention, the moving component includes a moving plate, a moving plate mounting plate, and a linear slide rail pair. A motor is connected to the moving plate, and the linear slide rail pair is embedded between the moving plate and the moving plate mounting plate. The moving plate is connected to the moving plate mounting plate via the linear slide rail pair. Under the action of the driving component, the moving plate moves along the linear slide rail pair. The embedding of the linear slide rail pair between the moving plate and the moving plate mounting plate reduces the distance between them, effectively preventing dust from entering, ensuring the accuracy of torque adjustment of the permanent magnet speed controller, and improving its service life.

[0009] In a preferred embodiment of the present invention, the drive assembly includes a mounting box, a worm gear mechanism, and a drive motor. The mounting box is mounted on the movable plate mounting plate of the movable assembly. The worm gear mechanism is located inside the mounting box and connected to the lead screw. The drive motor is located outside the mounting box and connected to the worm gear mechanism. The worm gear mechanism moves under the action of the drive motor, driving the lead screw to rotate. The worm gear mechanism prevents changes in the distance between the permanent magnet rotor and the conductor rotor due to vibration, ensuring the accuracy of torque adjustment of the permanent magnet speed regulator.

[0010] In a preferred embodiment of the present invention, the height adjustment assembly includes an upper mounting plate, a lower mounting plate, and a hydraulic push rod. The upper mounting plate and the lower mounting plate are connected by the hydraulic push rod. The upper mounting plate is connected to the movable component, and the lower mounting plate is connected to the fixed base. The distance between the upper mounting plate and the lower mounting plate is adjustable by the hydraulic push rod. The height adjustment assembly facilitates the adjustment of the motor's installation height as needed and has strong versatility.

[0011] In a preferred embodiment of the present invention, the dustproof component includes a dustproof plate and a bellows dust cover. The dustproof plate is disposed at the rear end of the movable plate mounting plate within the movable component and inserted into the movable plate mounting plate. The bellows dust cover is disposed at the front end of the movable plate mounting plate. One end of the bellows dust cover is connected to the movable plate within the movable component, and the other end is connected to the movable plate mounting plate. When the movable plate moves relative to the movable plate mounting plate, the dustproof plate and the bellows dust cover unfold to prevent external dust from entering. The dustproof component facilitates the blocking of falling dust when adjusting the distance between the permanent magnet rotor and the conductor rotor of the permanent magnet speed controller, preventing dust from entering the movable component and ensuring the accuracy of the torque adjustment of the permanent magnet speed controller.

[0012] In a preferred embodiment of the present invention, a dust removal scraper is provided on the dustproof plate. When the moving plate is reset, the dust removal scraper automatically cleans the dust and debris on the dustproof plate. The dust removal scraper facilitates the automatic removal of dust and debris from the dustproof plate, prevents dust from entering the moving component, and ensures the accuracy of the torque adjustment of the permanent magnet speed controller.

[0013] In a preferred embodiment of the present invention, the speed controller protection unit includes a protective cover and a heat dissipation component. The heat dissipation component is disposed inside the protective cover. The protective cover shields and protects the permanent magnet speed controller, while the heat dissipation component dissipates heat from the permanent magnet speed controller, thereby improving its service life. The arrangement of the heat dissipation component facilitates heat dissipation from the permanent magnet speed controller, thus improving its service life.

[0014] In a preferred embodiment of the present invention, the heat dissipation component includes an air inlet, a heat dissipation outlet, and an air duct. The air duct is disposed inside the protective cover, and the air inlet and the heat dissipation outlet are disposed on the mounting base of the protective cover. Cold air enters the air duct through the air inlet to dissipate heat from the permanent magnet speed regulator and is then discharged through the heat dissipation outlet. This arrangement improves the air circulation effect, enhances the heat dissipation effect, and also extends the service life of the permanent magnet speed regulator.

[0015] The advantages of this utility model compared with the prior art are:

[0016] The technical solution of this utility model utilizes a movable component within the mounting section to adjust the distance between the permanent magnet rotor and the conductor rotor of the permanent magnet speed controller, thereby achieving torque adjustment. A height adjustment component allows for adjustment of the motor height when needed, offering strong applicability. A dustproof component mounted on the movable plate automatically shields the movable component during torque adjustment, effectively preventing dust from entering and ensuring the stability and accuracy of torque adjustment. The speed controller protection section effectively protects the permanent magnet speed controller from external dust and debris. Simultaneously, the heat dissipation component within the speed controller protection section continuously dissipates heat from the permanent magnet speed controller, ensuring normal operation, extending its lifespan, and eliminating the need for frequent maintenance. This convenient use reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-11 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0030] like Figure 1 As shown, a cylindrical maintenance-free permanent magnet speed controller with a movable base includes a motor 1, a permanent magnet speed controller, a mounting part 2, and a speed controller protection part 7. The permanent magnet rotor 11 inside the permanent magnet speed controller is connected to the load, and the conductor rotor 12 is connected to the motor 1. The motor 1 drives the load to move through the permanent magnet speed controller. The motor 1 is mounted on the ground through the mounting part 2. The speed controller protection part 7 is placed on the ground and covers the outside of the permanent magnet speed controller. The speed controller protection part 7 can protect and dissipate heat from the permanent magnet speed controller, thereby improving the service life of the permanent magnet speed controller.

[0031] The main function of the mounting part 2 is to serve as a carrier for mounting the motor 1. At the same time, the motor 1 can adjust the gap between the permanent magnet rotor 11 and the conductor rotor 12 in the permanent magnet speed controller under the action of the mounting part 2, thereby realizing the adjustment of the load.

[0032] The main function of the speed controller protection section 7 is to protect the permanent magnet speed controller, enabling it to be used in complex and harsh working environments, avoiding frequent maintenance, and extending the service life of the permanent magnet speed controller.

[0033] like Figure 1 , 2As shown in Figures 3, 4, and 5, the mounting part 2 includes a fixed base 21, a motor mounting plate 22, a moving component 3, a height adjustment component 4, a drive component 5, and a dustproof component 6. The motor 1 is connected to the moving component 3 via the motor mounting plate 22. The height adjustment component 4 connects the moving component 3 and the fixed base 21. The fixed base 21 is fixed to the mounting surface with screws. The drive component 5 is located at the end of the moving component 3 and can drive the moving component 3 to move, thereby adjusting the gap between the permanent magnet rotor 11 and the conductor rotor 12 in the permanent magnet speed controller. The dustproof component 6 is located on the moving component 3 and can prevent dust from falling into the moving component 3 when adjusting the gap between the permanent magnet rotor 11 and the conductor rotor 12 in the permanent magnet speed controller.

[0034] The motor mounting plate 22 is a metal plate with a certain thickness. Its main function is to fix the motor 1. The motor 1 can be connected to the moving component 3 through the motor mounting plate 22.

[0035] The moving component 3 includes a moving plate 31, a moving plate mounting plate 32, and a linear slide rail pair 33. The moving plate 31 and the moving plate mounting plate 32 are rectangular metal plates with a certain thickness. Mounting holes are provided on the surface of the moving plate 31. The moving plate is connected to the motor mounting plate 22 by screws. The linear slide rail pair 33 connects the moving plate 31 and the moving plate mounting plate 32. The moving plate 31 can move relative to the moving plate mounting plate 32 under the action of the linear slide rail pair 33.

[0036] To reduce the gap between the movable plate 31 and the movable plate mounting plate 32, a slider mounting groove 39 for fixing the slider is provided on the surface of the movable plate mounting plate 32. The slider in the linear guide pair 33 is fixed in the slider mounting groove 39 by screws. The upper surface of the slider installed in the slider mounting groove 39 is slightly lower than the upper surface of the movable plate mounting plate 32.

[0037] Rectangular grooves are provided on the upper surface of the moving plate mounting plate 32 and the lower surface of the moving plate 31, corresponding to the slider mounting groove 39. The slide rail in the linear slide rail pair 33 is fixed in this rectangular groove by screws. That is, half of the slide rail in the linear slide rail pair 33 is embedded in the moving plate 31 and the other half is embedded in the moving plate mounting plate 32. This arrangement can reduce the gap between the moving plate 31 and the moving plate mounting plate 32, prevent external dust and debris from falling in, ensure the stable operation of the moving component 3, and also improve the accuracy of the torque adjustment of the motor 1.

[0038] Definition: In this embodiment, the mounting surface is used as a reference. The direction from the mounting surface to the motor 1 is upward, and the direction from the motor 1 to the mounting surface is downward. The direction from the motor 1 to the load is forward, and the direction from the load to the motor 1 is backward.

[0039] To facilitate the movement of the movable plate 31, a T-shaped lead screw fixing seat 37 is fixed to the bottom of the movable plate 31 with screws. A lead screw 38 is installed in the lead screw fixing seat 37. At the same time, a corresponding sliding groove for the lead screw fixing seat 37 to move is opened on the movable plate mounting plate 32. This sliding groove is named the fixing seat moving sliding groove 36. Rotating the lead screw 38 can drive the movable plate 31 to move. When the movable plate 31 moves, the lead screw fixing seat 37 can move within the fixing seat moving sliding groove 36.

[0040] To facilitate the installation of the dustproof plate 61 in the dustproof assembly 6, a rectangular groove is recessed perpendicular to the end face at the end of the movable plate 31. This groove is named the dustproof plate mounting groove 34. The dustproof plate 61 can be movably inserted into the dustproof plate mounting groove 34.

[0041] There is a rectangular groove recessed on the lower surface of the movable plate 31 near the edge. This groove is named the accordion cover guide groove 35. When the movable plate 31 moves, the accordion dust cover 62 can move along the accordion cover guide groove 35 to realize the unfolding of the accordion dust cover 62.

[0042] like Figure 1 , 2 As shown in Figures 3 and 6, the drive assembly 5 includes a mounting box 51, a worm gear mechanism 52, and a drive motor 53. The drive motor 53 is fixed in the mounting box 51 with screws. The worm gear mechanism 52 is installed in the mounting box 51 and is connected to the drive motor 53 and the lead screw 38. The drive motor 53 can transmit power to the lead screw 38 through the worm gear mechanism 52.

[0043] Mounting box 51 is a two-part rectangular plastic box that is connected by screws to form a complete mounting box 51. Its main function is to mount the worm gear mechanism 52 and the drive motor 53.

[0044] The worm in the worm gear mechanism 52 is connected to the drive shaft of the drive motor 53. The worm wheel in the worm gear mechanism 52 is mounted in the mounting box 51 through a mounting shaft. The drive motor 53 and the worm can drive the worm wheel to rotate.

[0045] To facilitate the rotation of the lead screw 38 by the drive motor 53, the rear end of the lead screw 38 passes through the outer wall of the mounting box 51 and is inserted into the mounting box 51. At the same time, a gear is fixed on the lead screw 38, which is named the driven gear 55. Meanwhile, a gear that can cooperate with the driven gear 55 is coaxially connected to the worm wheel in the worm gear mechanism 52, which is named the driving gear 54. The driving gear 54 is coaxially connected to the worm wheel and can rotate synchronously with the worm wheel. In this way, the lead screw 38 can be rotated by the drive motor 53 and the worm gear mechanism 52, so as to adjust the position of the moving plate 31.

[0046] like Figure 1 and 2 As shown, the height adjustment assembly 4 includes an upper mounting plate 41, a lower mounting plate 42, and a hydraulic push rod 43. The hydraulic push rod 43 is installed between the upper mounting plate 41 and the lower mounting plate 42. The distance between the upper mounting plate 41 and the lower mounting plate 42 can be adjusted by the hydraulic push rod 43, thereby adjusting the height of the motor 1.

[0047] The upper mounting plate 41 and the lower mounting plate 42 are rectangular metal plates with movable thickness. The upper mounting plate 41 is connected to the movable mounting plate 32 by screws, and the lower mounting plate 42 is connected to the fixed base 21 by screws.

[0048] The hydraulic push rod 43 is an existing manually adjustable hydraulic rod. The upper end of the hydraulic push rod 43 is connected to the upper mounting plate 41 by screws, and the lower end is connected to the lower mounting plate 42 by screws. The distance between the upper mounting plate 41 and the lower mounting plate 42 can be adjusted by the hydraulic push rod 43, which facilitates the adjustment of the height of the motor 1.

[0049] like Figure 7 , 8 As shown in Figure 9, the dustproof assembly 6 includes a dustproof plate 61 and an accordion dustproof cover 62. One end of the dustproof plate 61 is fixed to the movable plate mounting plate 32, and the other end is movably inserted into the dustproof plate mounting groove 34 of the movable plate 31. One end of the accordion dustproof cover 62 is fixed to the front end of the movable plate 31, and the other end is fixed to the front end of the movable plate mounting plate 32. When the movable plate 31 moves relative to the movable plate mounting plate 32, the accordion dustproof cover 62 unfolds.

[0050] The dustproof plate 61 is a thin metal plate with a "U" shaped cross-section. Rectangular holes are provided on both sides of the dustproof plate 61, which are named dustproof plate guide holes 63. The front end of the dustproof plate 61 is inserted into the dustproof plate mounting groove 34. Screws are installed on the side of the movable plate 31. The screws pass through the dustproof plate guide holes 63. When the movable plate 31 moves, it moves along the dustproof plate guide holes 63. The rear end of the dustproof plate 61 is fixed to the rear end of the movable plate mounting plate 32 by screws. In this way, when the movable plate 31 moves, it moves along the dustproof plate guide holes 63, and the dustproof plate 61 does not move.

[0051] To facilitate the removal of dust from the dustproof plate 61, a dust removal scraper 64 is fixed to the end of the dustproof plate 61 with screws. The dust removal scraper 64 has a triangular cross-section, and its lower surface is in contact with the upper surface of the dustproof plate 61. To facilitate the fixing of the dust removal scraper 64, a rectangular scraper fixing plate 66 is fixed to the dust removal scraper 64. The dust removal scraper 64 is fixed to the dustproof plate 61 with screws through the scraper fixing plate 66.

[0052] The accordion dust cover 62 is largely the same as the existing accordion dust cover 62. Its main function is to prevent dust from entering the moving component 3 from the front end. In order to improve the sealing performance, a rectangular protrusion is fixed on one end of the accordion dust cover 62 near the moving plate mounting plate 32. This protrusion is named dust removal plug 65. When the moving plate 31 moves, the dust removal plug 65 can move along the accordion dust cover guide groove 35, thereby unfolding the accordion dust cover 62. At the same time, the dust removal plug 65 can also squeeze out the dust in the accordion dust cover guide groove 35.

[0053] like Figure 10 and 11 As shown, the speed controller protection section 7 includes a protective cover 71 and a heat dissipation component 72. The heat dissipation component 72 is disposed inside the protective cover 71, which covers the outside of the permanent magnet speed controller. The protective cover 71 can prevent external dust and debris from falling into the permanent magnet speed controller, and the heat dissipation component 72 can dissipate heat for the permanent magnet speed controller, thereby improving the service life of the permanent magnet speed controller.

[0054] The protective cover 71 is made of metal and includes an upper cover 73 and a lower cover 74. The upper cover 73 and the lower cover 74 are connected by screws to form a complete protective cover 71. In order to facilitate the connection between the protective cover 71 and the permanent magnet speed controller, a bearing is fitted at the connection between the protective cover 71 and the load shaft and the drive shaft. At the same time, in order to facilitate the adjustment of the gap between the permanent magnet rotor 11 and the conductor rotor 12, a movable slide is fitted on the inner ring of the bearing to facilitate the adjustment of the gap. This is the prior art and will not be described in detail here.

[0055] To facilitate the fixing of the protective cover 71, a mounting base 75 is welded on the lower cover 74, and the protective cover 71 is fixed to the mounting surface by the mounting base 75.

[0056] To facilitate heat dissipation of the permanent magnet speed controller, a heat dissipation assembly 72 is provided inside the protective cover 71. The heat dissipation assembly 72 includes an air inlet 76, a heat dissipation outlet 77, and an air duct 78. The air inlet 76 and the heat dissipation outlet 77 are rectangular openings, respectively located on both sides of the mounting base 75 and connected to the protective cover 71. Cool air enters the air duct 78 through the air inlet 76, is guided by the air duct 78, and blows towards the permanent magnet speed controller inside the protective cover 71. After circulating inside the protective cover 71, it is discharged through the heat dissipation outlet 77. Two sets of cooling fans 79 are installed at the air inlet 76, which can blow cooling air into the protective cover 71. To prevent dust from entering the protective cover 71, a dust filter 710 is also provided at the air inlet 76.

[0057] The air duct 78 is composed of multiple arc-shaped partitions 712. The partitions 712 are welded to the inner arc surfaces of the upper cover 73 and the lower cover 74. Two adjacent partitions 712 are then welded together to form individual chambers. Multiple circular holes are evenly opened on the arc surface of each chamber. These holes are called air outlets 711. The cold air blown into the chamber is blown out through the air outlets 711 to cool the permanent magnet speed controller.

[0058] To facilitate the circulation of cold air, the air duct 78 on the upper cover 73 is connected to the air duct 78 on the lower cover 74, and the air duct 78 on the lower cover 74 is only half-set, that is, the air duct 78 on the lower cover 74 is only set to the position near the heat dissipation port 77, and the air duct 78 on the lower cover 74 is connected to the air inlet 76.

[0059] Regarding the air-cooling circulation inside the protective cover 71: Under the action of the cooling fan 79, the cold air from the outside enters the air duct 78 through the air inlet 76, is guided by the air duct 78 and blown out through the air outlet 711, blown towards the permanent magnet speed regulator inside the protective cover 71, and after circulating inside the protective cover 71, is discharged to the outside through the heat dissipation port 77, thus completing the air-cooling circulation.

[0060] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
