STRUCTURE FOR CONNECTING SHAFTS AND SHIP HAVING THE SAME

摘要

A rotary shaft connection structure is provided. The rotary shaft connection structure according to an embodiment of the present invention is selectively connected to a first rotary shaft to be able to rotate a second rotary shaft with the first rotary shaft, wherein the second rotary shaft is concentrically arranged on the first rotary shaft. The rotary shaft connection structure comprises: a coupling part for selectively coupling one end of the first rotary shaft to one end of the second rotary shaft to rotate one end of the first rotary shaft with one end of the second rotary shaft facing one end of the first rotary shaft; a movable shaft positioned on the second rotary shaft to move in the direction of the first rotary shaft; a movable shaft coupling groove formed on the first rotary shaft to receive the movable shaft when the movable shaft moves in the direction of the first rotary shaft; and a movable shaft moving unit installed in the second rotary shaft to move the movable shaft in the direction of the first rotary shaft.
