MAGNETIC TRANSMISSION APPARATUS

摘要

A magnetic transmission apparatus is disclosed, wherein the magnetic transmission apparatus includes a still part (4), a first rotating shaft (81), a second rotating shaft (82), a first rotating part (1), a second rotating part (2), and a third rotating part (3); the first rotating part (1) is rigidly connected with the first rotating shaft (81); the second rotating part (2), the third rotating part (3) are fixed on the second rotating shaft (82); the first rotating part (1), the second rotating part (2), and the third rotating part (3) are successively distributed along an axial direction; the still part (4) includes a magnetic regulation seat (41) and a magnetic regulation ring (42); the second rotating part (2) is located inside the magnetic regulation ring (42); the first rotating part (1) includes a first iron core (11), a first permanent magnet (12), and a first support part (811); the second rotating part (2) includes a second iron core (21), and a second permanent magnet (22); the third rotating part (3) includes a third iron core (31), a third permanent magnet (32), and a second support part (821); the first iron core (11), the first permanent magnet (12), the magnetic regulation ring (42), the third permanent magnet (32) and the third iron core (31) are successively distributed along the axial direction. The first permanent magnet (12) and the third permanent magnet (32) are magnetized alternately and axially; the second permanent magnet (22) is magnetized alternately radially. The magnetic transmission apparatus has an axially and radially mixed magnetic circuit and can take full advantage of the magnetic modulation space and improve the torque density.
