Title:
DRIVE TRANSMISSION DEVICE AND DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/112045
Kind Code:
A1
Abstract:
A drive transmission device (41) includes a driving-side rotating body (45), a plurality of magnetic transmission parts (46, 46x), and a driven-side rotating body (47). The driving-side rotating body has a plurality of magnet poles (45n, 45s) in the rotation direction. The plurality of magnetic transmission parts are capable of being excited by the magnet poles of the driving-side rotating body, and arranged separated from each other magnetically in the rotation direction. The driven-side rotating body has a plurality of magnet poles (47n, 47s) in the rotation direction, and rotates in response to rotation of the magnet poles of the driving-side rotating body transmitted through the magnetic transmission parts. By changing the number of magnet poles of the driving-side rotating body, the number of magnetic transmission parts, and the number of magnet poles of the driven-side body, the drive transmission device also functions as a magnetic speed-changing unit for changing the rotation speed between the driving-side rotating body and the driven-side rotating body. All or a portion of the magnetic transmission parts are integrally incorporated in a partition wall member.
