The controller adjusts the relative position of the cylindrical permanent magnet rotor and the cylindrical conductor rotor in the axial direction to change the effective coupling part of the permanent magnet rotor and the conductor rotor, thereby changing the torque transmitted between them. It can achieve repeatable, adjustable and controllable output torque and speed, and achieve the purpose of speed regulation and energy saving.

[0023] This invention provides an improved device that enables precise load speed regulation via a combination of bevel gears, the working principle of which is as follows; When using this device, first place it in the work area, and then connect it to an external power source to provide the necessary electrical energy for the device to work. When this device is needed, the controller 14 can be started first to send a start command to the drive motor 12 via the data cable 13. The drive motor 12 drives the drive motor spindle 21 to rotate. The drive motor spindle 21 engages with the inner spline 27 of the magnetic drum 26 via the outer spline 22, driving the magnetic drum 26 to rotate synchronously. Since there is an air gap 29 between the magnetic drum 26 and the permanent magnet rotor 35, the rotating permanent magnetic field of the magnetic drum 26 cuts the magnetic field lines in the magnetic drum 26, generating a strong eddy current. This eddy current induces a magnetic field that interacts with the permanent magnetic field, thus "dragging" the permanent magnet rotor 35 to rotate synchronously. The permanent magnet rotor 35 then drives the transmission spindle 36 to rotate, realizing the transmission of power from the drive motor 12 to the transmission spindle 36. When speed adjustment is required, the dual-axis motor 41 can be started to drive the output shafts at both ends to rotate the first bevel gear 42 and the third bevel gear 45 respectively. The first bevel gear 42 drives the second bevel gear 43 that meshes with it, thereby driving the first threaded rod 44 to rotate. Similarly, the third bevel gear 45 on the other side drives the fourth bevel gear 46 and the second threaded rod 47 to rotate synchronously. The first threaded rod 44 and the second threaded rod 47 mesh with the screw nuts 25 fixed on both sides of the axially movable housing 23. Therefore, when the threaded rod rotates, it will drive the entire axially movable housing and the magnetically conductive drum 26 inside it to move precisely forward or backward along the limiting slide bar 48 and the main shaft 21 of the drive motor, thereby reducing or increasing the air gap 29 between it and the permanent magnet rotor 35, realizing stepless speed regulation. The sliding groove 39 on the limiting slide bar 48 and the limiting frame 37 ensures the stability and straightness of the movement process and prevents the housing from rotating.

[0024] Example 2: Please see Figures 1-6The present invention provides a device for precise load speed regulation via a bevel gear combination transmission. Compared to Embodiment 1, this embodiment further includes a self-adjusting cooling assembly 5 comprising a heat-conducting ring 51, an annular water-conducting pipe 52, heat dissipation fins 53, a water inlet pipe 54, a water outlet pipe 55, a valve 56, a gear 57, a rack 58, and a fixing base 59. The heat-conducting ring 51 is fixedly connected to the side of the axially movable housing 23, and the annular water-conducting pipe 52 is fixedly connected to the outer surface of the heat-conducting ring 51. The heat-conducting ring 51 is tightly fitted to the axially movable housing 23 of the heat source, efficiently dissipating heat. The heat dissipation fins 53 are fixedly connected to the outer surface of the annular water guide pipe 52. The water inlet pipe 54 is fixedly connected to the upper rear end of the annular water guide pipe 52. The water outlet pipe 55 is fixedly connected to the upper rear end of the annular water guide pipe 52. The valve 56 is fixedly connected to the left end of the bushing fixing block 33. The middle part of the gear 57 is fixedly connected to the left end of the valve 56. The front end of the rack 58 is fixedly connected to the left end of the axially movable housing 23. The upper tooth surface of the rack 58 meshes with the lower end of the gear 57. The upper end of the fixing seat 59 is slidably connected to the front end of the rack 58. The middle part of the fixing seat 59 is slidably connected to the middle part of the limiting slide rod 48.

[0025] In this embodiment: The heat generated during speed regulation is conducted from the high-speed rotating axially moving housing 23 to the heat-conducting ring 51 fixedly connected to it. Circulating cooling water enters the annular water guide pipe 52 from the inlet pipe 54, flows through the pipe surrounding the heat-conducting ring, carries away the heat, and finally exits from the outlet pipe 55. The heat dissipation fins 53 further enhance the heat dissipation effect. When it is necessary to increase the speed and reduce the air gap, the axially moving housing 23 will move forward, and the rack 58 fixed on it will move forward synchronously. The rack 58 drives the gear 57 meshing with it to rotate. The rotation of the gear 57 directly drives the valve core of the valve 56 to rotate, increasing the valve opening. When the equipment enters a high-load / high-speed working state, the cooling water flow rate automatically increases to cope with the greater heat generation. When the equipment load decreases and the air gap increases, the axially moving housing moves backward, and the valve is closed through the rack and pinion mechanism to reduce the cooling water flow rate and avoid energy waste and overcooling.

[0026] This invention provides an improved device that enables precise load speed regulation via a combination of bevel gears. A controller 14 precisely controls the drive motor 12, while a protective cover 15 and a screw protective tube 16 enhance protection and ensure stable operation. The rotor assembly 2 utilizes a spline sliding mechanism and an air gap 29 to lay the foundation for flexible speed regulation. The transmission assembly 3 uses a reinforcing frame 31 and a bushing fixing block 33 to enhance structural stability and ensure reliable power transmission. The adjustment assembly 4, through the collaboration of bevel gears, a dual-shaft motor, and a threaded rod, enables precise axial adjustment of the magnetically guided drum 26, achieving flexible speed regulation. The self-adjusting cooling assembly 6 uses gears 57 and racks 58 linked to a valve 56 to automatically adjust cooling as the machine moves axially, adapting to different working conditions. Overall, this improves the flexibility of load speed regulation, operational stability, and heat dissipation efficiency, extending the equipment's service life.
