Title:
NON-CONTACT DRIVE TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2018189221
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact drive transmission device capable of reducing cost without needing groove processing by eliminating the need of magnetization processing of each product and simplifying work.SOLUTION: A non-contact drive transmission device 10 includes: a cylindrical driving member 100 which rotates around the axis of a cylinder, in which magnetic poles having different polarities are alternately magnetized on the peripheral surface of the cylinder with the same width; two first magnet units 122 including a pair of principal planes and short sides arranged perpendicular to the pair of principal planes to face each other, in which magnetic poles having different polarities are alternately arranged on one principal plane with the same width of the magnetic poles of the driving member 100 from one short side to the other short side of facing short sides to undergo magnetization; and a support member 121 for supporting the first magnet units 122. The two first magnet units 122 are arranged while one short side of the facing short sides of the first magnet units 122 faces one short side of the other first magnet unit 122. One magnetic pole of the first magnet units 122 is arranged, facing one magnetic pole of the driving member 100.SELECTED DRAWING: Figure 1
