Title:
MAGNETIC ROTATION TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2678569
Kind Code:
B2
Abstract:
PURPOSE: To increase rotation torque without enlarging thrust load and enable the instantaneous changeover of normal and reverse rotation by adding repulsion as well as making a curved magnetic force line.
CONSTITUTION: This transmitter is equipped with a right and left two poles type of magnet 11, which has a pair of magnetic pole faces at right and left, and a planar both-sided two poles type of magnet 12, which has a pair of magnetic pole faces at obverse and reverse. The both-sided two poles type of magnet 12 is counterposed, so that the magnetic pole face may parallel the center extension 13, on the center extension 13 of the right and left two poles type of magnet 11. By rotating either magnet 11 or 12 around the axis of the center extension 13, the rotation is transmitted to the other magnet 12 or 11 by magnetic force. The magnetic force line contributing to the suction force made between opposed unlike poles curves, and the magnetic force line contributing to repulsion contributes to the transmission of rotation, too.
