Title:
ROTATION POWER TRANSMISSION MECHANISM
Document Type and Number:
Japanese Patent JP2018080723
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation power transmission device which can contactlessly transmit rotation power, and can suppress a slip.SOLUTION: A rotation power transmission mechanism comprises: an input shaft 11 and an output shaft 21 which are separated from each other; a first rotating member 12 fixed to a tip of the input shaft 11 at an output shaft side; and a second rotating member 22 fixed to a tip of the output shaft 21 at an input shaft side, and arranged so as to oppose the first rotating member 12. A protrusion 24 which is formed around a rotating shaft of the other of the first and second rotating members is inserted into a recess 14 which is formed around a rotating shaft of either of the first and second rotating members, the first rotating member 12 and the second rotating member 22 are connected to each other so as to be relatively turnable, and permanent magnets 13, 23 are arranged at a pair of contact faces of the recess 14 and the protrusion 24, respectively, so that the recess 14 and the protrusion 24 repel to each other in a pair of the contact faces at which the recess 14 and the protrusion 24 contact with each other by the relative turns.SELECTED DRAWING: Figure 1
