Abstract:
A flexible joint for transferring torque from a shaft of a drive device to a shaft of a driven device, the flexible joint comprising:a first rotating body to be connected to one of the shaft of the drive device and the shaft of the driven device; a second rotating body that is coaxially connected with the first rotating body and has an outer circumferential wall and an inner wall, the inner wall being rotatably held by an other one of the shaft of the drive device and the shaft of the driven device; a third rotating body to be connected to the shaft of the other one of the shaft of the drive device and the shaft of the driven device, the third rotating body being provided with a torque limiter for interrupting a torque transmission from the shaft of the drive device to the shaft of the driven device via the first rotating body and the second rotating body when torque applied to the third rotating body exceeds a predetermined value; an elastically deformable first damper through which the second rotating body is coaxially coupled with the third rotating body at a position inside the outer circumferential wall and outside the inner wall; and an elastically deformable second damper disposed between an outer circumference of the first rotating body and an inner circumference of the second rotating body to transfer the torque between the first rotating body and the second rotating body.
