Meshing-area-adjusting type synchronous magnetic torque converter and speed regulation method thereof

Abstract

The invention discloses a meshing-area-adjusting type synchronous magnetic torque converter and belongs to the technical filed of transmission in mechanical engineering. The torque converter comprises an outer rotor assembly, an inner rotor assembly and a speed regulation device assembly, wherein single thread screws are driven to rotate through controlling of rotation of a micro electrical motor and through a reducing mechanism, a thread ends of the single thread screws are in threaded connection with an inner rotator body in the inner rotor assembly, screwing directions of threads at two ends of two single thread screws in the same group are the same, the rotating directions are opposite, and when a single thread screws rotates around an axis, a left inner rotor body and a right inner rotor body can move in and move out along a driven shaft, so that the meshing area between a left permanent magnet and a left copper bar and the meshing area between the right permanent magnet and a right copper bar are changed simultaneously, the air-gap field strength is regulated, the output of different rotating speeds and torques is achieved; and each group of speed regulation mechanisms are distributed and installed at an interval of 120 degrees axially and evenly, so that a balanced state of the whole device during operation is guaranteed, and the reliability and the stability of the operation of the device are guaranteed.
