SHIP PEUROPELRA'S AUTOMATIC SHIFT STRUCTURE

摘要

PURPOSE: An automatic shift structure for a ship is provided to prevent a power transmission shaft and a proper from being touched with peripheral foreign materials because the power transmission shaft and the propeller installed in a small ship are drawn in and out through the upper part of a stern on land. CONSTITUTION: An automatic shift structure for a ship comprises a hull(10) and a propeller(20). A mounting groove(13) is formed on the underside(12) of the hull and is extended to the downward of a stern(11). A propeller bracket(21) is inserted in the mounting groove to couple to an access part(30). Side pieces(212) are coupled to the upper and lower ends of the propeller bracket between upper and lower horizontal members(211). A propeller rotating part(23) is coupled inside the side pieces. A direction blade(24) is coupled between the upper and lower horizontal members. The access part comprises a link part and a rod type access portion(32). The link part is coupled to a front underside of the mounting groove and the side pieces. The rod type access portion is arranged above the upper horizontal member and the stern.
