PROBLEM TO BE SOLVED: To provide a coupling device for a cylindrical hollow shaft in such a way as capable of disengaging, manufacturable simply, and furnished with ring flanges wherein the ends of the hollow shaft can be fitted to each other in the axial direction in such a condition as overlapped one over another. SOLUTION: The coupling device for hollow shaft includes two flanges RFH and RFR, and two or more rock bolts RB are installed movably in the radial direction within the ring flange RFH positioned inside, and within the other ring flange positioned outside, a rock bushing RBU with two sides left open is installed in such a way as directed to the rock end RE of each rock bolt RB for accommodating the rock bolts, wherein the other end of each rock bolt RB is put under screw guidance within the ring flange RFH positioned inside, and each rock bolt is furnished with a circumferential pinion UFR between its two ends. |
