摘要
High speed rotation Problem to be solved: to provide a transmission transmission mechanism capable of completely interrupting electromagnetic noise passing through a wall of an electromagnetic darkroom or an EMC test of rotating electrical equipment such as a motor in various conditions such as a low speed rotation high torque, a high-speed rotation low torque, and the like, which can be suppressed as small as possible.In the rotation transmission apparatus, the rotary shaft 1 made of fiber reinforced plastic is supported by the bearing 4 in the conductive housing 2 to make the electrical conduction between the conductive housing 2 and the rotary shaft 1 in order to enable the rotation transmission with high rotational torque Conductive fiber brush 5 is provided.A plurality of bearings may be used in addition to both ends to enable the rotation transmission at high rotational torque.Diagram
