にして複数個の永久磁石を周設した磁石支持リン
グを、端部にローターを嵌着した回転軸の軸線方
向に永久磁石の極面が所要空隙でローターに全面
対向する位置から全面離脱する位置までの長さを
進退自在に組込んだ減速装置において、ピストン
のもどり行程はばね力で後退できるようにコイル
ばねを装着したエアーシリンダの複数を装置枠側
面に円周配設し、ピストンロツド先端を上記磁石

式減速装置。 A magnet support ring with a plurality of permanent magnets arranged around it so that the polarities of adjacent magnets are opposite to each other is installed so that the pole faces of the permanent magnets have the required air gap in the axial direction of the rotating shaft with the rotor fitted to the end. In this deceleration device, the length from the position where it fully faces the rotor to the position where it fully leaves the rotor can be moved back and forth.In this deceleration device, multiple air cylinders equipped with coil springs are installed so that the return stroke of the piston can be moved backward by spring force. An eddy current reduction gear that has a safety device that is circumferentially disposed on the side of the frame and has a piston rod tip connected to the magnet support ring.
