Abstract

The invention discloses an air-cooled speed-regulating permanent magnet coupler, which comprises a motor shaft, a casing is fixedly connected to the motor shaft, a conductor disc is fixedly connected to the inner wall of the casing, and the right side of the motor shaft is arranged There is a load shaft, a pair of movable discs are slidably connected to the load shaft, a group of permanent magnets are slidably connected to the movable discs, the movable discs are arranged on the inner side of the conductor disc, and the movable discs are driven to move by an axial drive device , the permanent magnet is driven to move by a radial drive device. The invention is an air-cooled speed-regulating permanent magnetic coupler with simple structure, high reliability and convenient adjustment.

Description

technical field [0001] The invention relates to the technical field of couplers, in particular to an air-cooled speed-regulating permanent magnetic coupler. Background technique [0002] There is no rigid connection between the permanent magnetic coupling load and the motor. The conductor rotor installed on the motor side rotates in the magnetic field generated by the permanent disk on the load side to generate an induced magnetic field and form an eddy current. The eddy current generates an induced magnetic field, and the torque formed by interacting with the permanent magnet rotor drives the load to rotate, and through the adjustment of the permanent disk and The gap between the conductors realizes the automatic adjustment of the motor power. However, most of the existing permanent magnetic couplers have the disadvantages of complex structure and poor reliability. Contents of the invention [0003] The purpose of the present invention is to provide an air-cooled speed-...
