PROBLEM TO BE SOLVED: To provide a rotation phase detector for a vibration compensator that can facilitate positioning of a phase detection sensor and reduce vibration of a hull.SOLUTION: A rotation phase detector 15 for a vibration compensator 1 which comprises an eccentric weight 14 fixed to a pair of rotary shafts 13 arranged in parallel respectively, and generates vibration in one direction from a casing 11 by rotating the rotary shaft 13 and rotating in synchronization the eccentric weight 14 in the opposite direction comprises a phase detection device consisting of a cover 21 provided to a casing 11 and allows one of the rotary shafts 13 to be inserted, a projection member 41 provided at an end of the rotary shaft 13 and provided atop of a small-diameter part 13a having a smaller diameter than the rotary shaft 13 to project radially, a guide rail 42 provided in the cover 21 and provided annularly having its center on the axis of the rotary shaft 13, an adjustment plate 43 capable of rotating along the guide rail 42, and a phase detection sensor 44 fixed to the adjustment plate 43 and detecting a phase of the projection member 41.SELECTED DRAWING: Figure 2 |
