Abstract

The invention discloses a spatial magnetic gear transmission belonging to the technical field of mechatronic engineering. The spatial magnetic gear transmission comprises a stator and two cone-shaped rotors, wherein the two rotors are arranged at a certain angle, the stator is embedded between the two rotors, and a non-contact structure with a gap is arranged between the two rotors and between the two rotors and the stator; the two cone-shaped rotors have same structures and respectively comprise a rotor shaft, a cone-shaped rotor base and a rotor pole, one sides of the conical surfaces of the two rotor bases are parallel, and the two rotor bases are provided with at least one pair of poles which are arranged in pairs and made of a permanent magnet material; the two rotor shafts are arranged at a certain angle on the same plane; the stator is made of a ferromagnetic material, and the two rotor shafts are pivoted with the stator of a supporting stator through a bearing. Due to the adoption of a non-contact structure, the spatial magnetic gear transmission has little abrasion and noise and no need of lubrication and is particularly suitable for occasions requiring spatial angular transmission. The spatial magnetic gear transmission has the advantages of simple structure, easiness in maintenance, high efficiency and long service life.

Description

technical field [0001] The invention belongs to the technical field of electromechanical engineering, in particular to a space magnetic gear transmission. Background technique [0002] The existing space gear transmissions are basically the direct contact type of mechanical gear meshing. The disadvantages are low efficiency, high noise, need for lubrication, and easy damage. The existing magnetic gears are coaxial or parallel to the axial transmission, and there is no realization scheme for angular transmission in space. Contents of the invention [0003] Aiming at the shortcomings of the mechanical space gear meshing direct contact type in the prior art, such as low efficiency, high noise, need for lubrication, easy damage, etc., the present invention applies the principle of magnetic field properties, refers to the characteristics of permanent magnet synchronous motors, and utilizes the rationality of permanent magnets and ferromagnetic materials. Combined, a non-contac...
