Disc type speed regulation magnetic coupler based on bevel gear drive

The invention relates to the technical field of transmission in mechanical engineering, specifically to a disc type speed regulation magnetic coupler based on bevel gear drive. The disc type speed regulation magnetic coupler consists of a driving disc assembly and a driven disc assembly, and a speed regulation device is mounted on the driving disc assembly. Through shifting of a shifting block, a shifting block pin fixedly connected with the shifting block performs axial displacement along a straight channel of a driving shaft, due to contact and cooperation of the shifting block pin and a large bevel gear sleeve chute, the large bevel gear sleeve is driven to rotate axially, and through meshing of a plurality of small bevel gears and a large bevel gear on a large bevel gear sleeve, rotation of the large bevel gear sleeve is converted into rotation of a permanent magnet assembly connected with the small bevel gears, thereby changing an average directly-facing area and air gap interval between the permanent ma
