Abstract

The invention relates to a magnetism transmission gear pair of a novel transverse magnetic field, which can be widely applied to wind power generation, electric cars, ship drive and other industrial transmission fields requiring direct drive. The magnetism transmission gear pair is characterized in that a driving wheel and a driven wheel of the magnetism transmission gear pair are of a flat disk shape, 2pr driving wheel permanent magnets 3 are distributed on the driving wheel, and 2ps driven wheel permanent magnets 7 are distributed on the driven wheel; a ferromagnetic magnetic modulation grid 6 playing a role of modulating an air-gap magnetic field is arranged between the driving wheel and the driven wheel, air gaps are reserved between the ferromagnetic magnetic modulation grid 6 and the end surfaces of the driving wheel and the driven wheel, and the ferromagnetic magnetic modulation grid 6, the driving wheel and the driven wheel have no mechanical contact and are distributed along the same axis; the air-gap magnetic field Bg passes through an air-gap plane along a route parallel to a rotation axis to form a transverse magnetic field of the magnetism transmission gear pair; and during working, power speed change transmission without mechanical contact and friction is realized by utilizing a principle of heteropolarity attraction of an N pole and an S pole of a permanent magnet material.

Description

technical field

[0001] The invention is a novel magnetic transmission gear pair of transverse magnetic field, which can be widely used in wind power generation, electric vehicles, ship drive and other industrial transmission fields requiring direct drive. Background technique

[0002] Among the methods for increasing the drag torque, the mechanical gear variable speed transmission is widely used, but the basic form of transmission has not changed for a long time, that is, the transmission is always carried out by the meshing of the two gear teeth of the mechanical gear pair. This brings some indelible problems to the gear transmission, such as mechanical fatigue, friction loss, vibration noise, etc. Although the grease lubrication technology can be used, the above problems still cannot be eradicated, resulting in extremely cumbersome use and maintenance, and the mechanical gear transmission. The theoretical efficiency can only reach 85% at most. The mechanical gear pair tran...
