Problems solved by technology

[0003] The axial permanent magnet speed governor adopts double permanent disks and double conductor disks, and the axial force is balanced. Generally, the speed is adjusted by changing the gap between the permanent disks and the conductor disks. However, since the magnetic blocks are installed on the disk, the radius of gyration is small. , making it larger in size, so the overal...

Abstract

The invention discloses a radial-clearance-adjustable permanent magnet speed regulation device. The speed regulation device is characterized by comprising a first barrel-type rotation assembly and a second barrel-type rotation assembly, wherein the first barrel-type rotation assembly and the second barrel-type rotation assembly are coaxially installed, and the outer surface of the second rotation assembly is provided with a permanent magnet or an electric conductor; the speed regulation device further comprises a push-pull sleeve connected with the permanent magnet or the electric conductor, and one end of the push-pull sleeve is connected with a clearance adjustment device. The speed regulation device is small in overall size, light in weight and large in transmission torque; a speed regulation mechanism is simple, and the radial clearance can be regulated in a labor-saving mode; the air-gap size can be changed, and also the coupling area can be changed.

Description

technical field [0001] The invention relates to a mechanical power transmission system in electromechanical engineering, in particular to a novel radial gap adjustable permanent magnet governor whose radial and axial gaps can be comprehensively adjusted. Background technique [0002] The adjustable magnetic coupler (CN1248354A) was invented by Magnadrive in the United States in 1999. In the transmission system composed of load equipment and motor, it has realized the functions of soft start, adjustable speed and overload protection. At present, there are no more than two types of permanent magnet governors for online applications: disc structure (axial type) and barrel structure (radial type). The axial permanent magnet governor adjusts the axial distance between the driving part and the driven part, that is, adjusts the air gap; the radial permanent magnet governor also adjusts the axial displacement to change the coupling area. [0003] The axial permanent magnet speed go...
