Abstract

The invention belongs to the technical field of magnetic gear transmission, and particularly relates to a magnetic-gathering Halbach small-range magnetic gear reducer which comprises a machine shell, an end cover and an input shaft, two pieces of stator magnetic steel are arranged on the inner wall of the machine shell side by side in a spaced mode, two rotor discs are arranged on the input shaft side by side in a sleeved mode, and the space phase difference between the two rotor discs is 180 degrees. Rotor magnetic steel is respectively sleeved on the two rotor discs, the input shaft is respectively provided with non-magnetic baffle plates at two sides of the single rotor magnetic steel, the two rotor discs are also jointly provided with a crankshaft in series, two ends of the crankshaft are respectively connected with the two end covers, and the stator magnetic steel and the rotor magnetic steel are respectively of a magnetism gathering Halbach array arrangement structure. The magnetic gear reducer breaks through the bottleneck of friction clearance of a mechanical gear and the like, and compared with a mechanical reducer, the magnetic gear reducer has the advantages of being low in noise, free of friction, high in efficiency, high in durability and the like.

Description

technical field

[0001] The invention belongs to the technical field of magnetic gear transmission, and in particular relates to a Halbach magnetic gear reducer with few pole differences, which uses magnetic gears to realize non-contact transmission. Background technique

[0002] In the field of industrial applications, it is often necessary to realize variable speed and variable torque transmission. For example, in the field of wind power generation and hydropower generation, it is necessary to convert the potential energy of extremely low-speed and variable wind energy and water into high-speed mechanical kinetic energy for power generation. In the field of electric vehicles and submarine drives It is also necessary to transform the high-speed mechanical power of the driving motor into a mechanical power with a very low rotational speed and a large torque. The existing conventional method is to use the mechanical gear variable speed transmission technology to achieve the re...
