Document Type and Number:
Japanese Patent JP2018162681
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic gear pump which is easily attached with a large number of magnets, and has large transmission torque by comprising a large number of magnets.SOLUTION: This magnet gear pump 1 comprises a device main body 2 for incorporating a magnet coupling part 5 constituting a magnet coupling mechanism therein, and a rotating body 6 constituting the magnet coupling part 5 is constituted of a cylinder body whose both end parts are opened, and at an internal peripheral part of which outer magnets 7 are arranged. An opening part of the rotating body 6 at an external drive source side is blocked by a block member 10 for fixing a drive shaft 4a connected to an external drive source. Therefore, when arranging the outer magnets 7 at the internal peripheral part of the rotating body 6, a plurality of outer magnets can be arranged while being aligned in an axial direction of the rotating body 6.SELECTED DRAWING: Figure 1
