Zusammenfassung:The present invention provides a coupling using carbon fiber, which is to improve accuracy by minimizing the generation of a torque ripple. The coupling using carbon fiber includes: a first ring unit installed in a ring shape for a first shaft unit to be inserted therein, wherein a first shaft insertion hole is formed by being penetrated at the center of the first ring unit in a longitudinal direction; a second ring unit arranged by being separated from the first ring unit in the longitudinal direction and installed in the ring shape for a second shaft unit to be inserted therein, wherein a second shaft insertion hole is formed by being penetrated at the center of the second ring unit and arranged in the longitudinal direction with the first shaft insertion hole; and a rotation transfer unit in which both ends are melted and connected to each outer circumference of the first ring unit and the second ring unit in a circumferential direction to transmit torque in which the torque ripple is corrected to the second ring unit when the first ring unit rotates and is twisted in the circumferential direction. The rotation transfer unit has multiple woven carbon fiber bodies arranged by crossing a first direction and a second direction vertical to the first direction. 토크리플 발생이 최소화되어 정밀도가 개선되도록, 본 발명은 제1축부가 삽입되도록 링형으로 구비되어 중앙부에 제1축삽입홀이 길이방향으로 관통 형성되는 제1링부; 상기 제1링부와 길이방향으로 이격 배치되되, 제2축부가 삽입되도록 링형으로 구비되어 중앙부에 제2축삽입홀이 상기 제1축삽입홀과 길이방향으로 정렬되며 관통 형성되는 제2링부; 및 상기 제1링부가 회전되면 원주방향을 따라 비틀린 상태에서 상기 제2링부에 토크리플이 보정된 회전력을 전달하도록 양단부가 상기 제1링부 및 상기 제2링부의 각 외주면에 원주방향을 따라 용융 결합되고, 복수개의 탄소섬유 직조체가 제1방향 및 상기 제1방향에 수직인 제2방향으로 교차 배열되는 형태로 구비되는 회전전달부를 포함하는 탄소섬유를 이용한 커플링을 제공한다.
