Title:

An annular magnetic pole member and a magnetic wave gear device

Document Type and Number:

Japanese Patent JP6265569

Kind Code:

B2

Abstract:

There are provided a core portion (2a) including a plurality of single layer units (U) laminated in a direction of a center axis (R), each of the single layer units (U) including a plurality of magnetic body pieces (2f) annularly arranged around the center axis (R) in a state where the magnetic body pieces (2f) are in contact with each other, and each of the magnetic body pieces (2f) including a plurality of openings (2g); and a plurality of fastening bolts (2b) that are respectively inserted through a plurality of penetration holes (2e) which are the plurality of openings (2g) continuously connected to each other in the direction of the center axis (R). In the single layer units (U) adjacent to each other, contact positions of the magnetic body pieces (2f) are different from each other.
