Description

Technical Field

[0001] The present invention relates to the field of permanent magnet speed regulators, and specifically to an adjusting device for a permanent magnet speed regulator. Background Art

[0002] A permanent magnet speed regulator is a device that uses magnetic force to achieve transmission. By adjusting the magnitude of the coupling magnetic field between the conductor rotor and the permanent magnet rotor, the output speed of the permanent magnet speed regulator is controlled. The way to adjust the coupling magnetic field between the conductor rotor and the permanent magnet rotor is usually to adjust the axial distance between the two. The permanent magnet speed regulator is equipped with an adjusting mechanism. Currently, the adjusting mechanism is usually installed at the permanent magnet rotor end or the conductor rotor end to adjust the axial movement of the permanent magnet rotor or the conductor rotor. However, this adjusting mechanism has a complex structure, poor reliability, and occupies a large axial space. When applied to the energy-saving transformation of the motor system, the foundation needs to be transformed, and the engineering quantity is large. Summary of the Invention

[0003] The object of the present invention is to solve the problems existing in the prior art, and provide an adjusting device for a permanent magnet speed regulator. This adjusting device solves the problems of the existing permanent magnet speed regulator such as complex structure, poor reliability, and large transformation engineering quantity, and provides an adjusting device for a permanent magnet speed regulator with a simple structure, convenient adjustment, and simple transformation.

[0004] The object of the present invention is solved by the following technical solutions:

[0005] An adjusting device for a permanent magnet speed regulator includes an adjusting assembly, a fixing assembly, and a positioning assembly. It is characterized in that: the adjusting assembly includes a lead screw, a slider, and a rotating wheel. The slider is fixedly connected to the fixing assembly, and the lead screw is rotatably connected to the positioning assembly; the fixing assembly is installed on the positioning assembly and can move axially along the positioning assembly; the motor is fixedly installed on the fixing assembly; the driving rotor of the permanent magnet speed regulator is installed on the output shaft of the motor and rotates synchronously with the output shaft; the driven rotor of the permanent magnet speed regulator is installed on the load shaft and drives the load shaft to rotate synchronously; when the rotating wheel is rotated, the lead screw rotates with the rotating wheel, so that the slider moves axially on the lead screw and drives the fixing assembly to move axially. The motor and the driving rotor fixed on the output shaft also move axially with the fixing assembly, and finally the distance between the driving rotor and the driven rotor is changed, completing the process of adjusting the output speed of the permanent magnet speed regulator.

[0006] The fixing assembly includes an adsorption permanent magnet, a cover plate, and a positioning bottom plate. The magnetic field direction of the adsorption permanent magnet is vertical and is encapsulated in the positioning bottom plate through the cover plate. The adsorption permanent magnet adsorbs the lower horizontal plane of the fixing assembly and the upper horizontal plane of the positioning assembly together by magnetic force, restricting the freedom degree of the fixing assembly in the vertical direction.

[0007] The outer vertical plane of the fixing assembly cooperates with the inner vertical plane of the positioning assembly to restrict the freedom degree of the fixing assembly in the horizontal direction.

[0008] The driving rotor of the permanent magnet speed regulator described above is a conductor rotor, and the driven rotor is a permanent magnet rotor.

[0009] The driving rotor of the permanent magnet speed regulator described above is a permanent magnet rotor, and the driven rotor is a conductor rotor.

[0010] The runner in the adjusting assembly is connected to the electric actuator, so as to realize on-line automatic adjustment.

[0011] The present invention has the following advantages compared with the prior art:

[0012] In the present invention, the motor is installed on the fixed assembly, and the adjusting mechanism is used to adjust the axial movement of the fixed assembly, so as to drive the axial movement of the motor and the driving rotor installed on the output shaft of the motor, change the coupling magnetic field between the driving rotor and the driven rotor, and achieve the purpose of adjusting the speed.
