The invention discloses a novel
magnetic gear for a two-way air-gap field. The novel
magnetic gear for the two-way air-gap field comprises a driving wheel, a driven wheel and a
magnetic field regulating grid, wherein the driving wheel and the driven wheel are coaxially mounted in a
stator housing. The driving wheel and the driven wheel are arranged on the two ends of the
magnetic field regulating grid respectively, and a gap is kept between the driving wheel and the driven wheel. Driving wheel permanent magnets are evenly distributed on the
peripheral face of a driving wheel inner ring at intervals. Driven wheel permanent magnets are evenly distributed on the
peripheral face of a driven wheel inner ring at intervals. A driven wheel assemble magnetic patch is arranged between the adjacent driving wheel and driven wheel.
Magnetic field regulating teeth are arranged on the periphery of the
magnetic field regulating grid inner ring. The arc lengths for both ends of the axial component of the T-shaped magnetic field regulating teeth are equal. An air-gap field forms a closed
magnetic circuit through an axial direction air gap and a radical direction air gap. No-
contact transmission is carried out under the interaction of the permanent
magnet and the magnetic field. The novel
magnetic gear for the two-way air-gap field has the advantages that transmission efficiency is high, reliability is high, abrasion caused by mechanical contact does not exist,
lubrication is not needed, the isolating between an input shaft and an output shaft is achieved, and the overload protection function can be achieved. The novel magnetic gear for the two-way air-gap field can be widely used in the
new energy field, such as
wind power generation, electromobiles, and electrical ships and warships.
