The invention discloses a stern cabin structure facilitating maintenance of a ship stern shaft bearing. The stern cabin structure comprises a stern cabin, and the stern cabin is defined by a top plate, a ship body outer plate and a stern peak bulkhead; the stern cabin is a stern void cabin; a plurality of non-watertight platforms are arranged between the tail shaft and the top plate; a first toggle plate and a second toggle plate are arranged below the tail shaft; a first opening part is formed in the afterpeak bulkhead; a watertight cover is arranged on the first opening part; an inner bottom plate is arranged below the tail shaft, and a plurality of transverse strong structural parts are arranged between the inner bottom plate and the non-watertight platform closest to the tail shaft; a second opening part is formed in the transverse strong structural member; the stern shaft penetrates through the second opening part. According to the invention, a propeller does not need to be disassembled by docking in the maintenance work of the propeller shaft bearing; the maintenance cost of the tail shaft bearing is lower, and the maintenance is more convenient; and the paint construction space is relatively larger, and the replacement period of the ship structure is longer due to the low-corrosion environment of the void.

本发明公开了一种利于船舶艉轴轴承维护的艉部舱室结构，其包括艉部舱室，艉部舱室由顶板、船体外板和艉尖舱壁围设而成；艉部舱室为艉空舱；艉轴和顶板之间设有若干非水密平台；艉轴下方设有第一肘板和第二肘板；艉尖舱壁上开设有第一开口部；第一开口部上设有水密盖；艉轴下方设有内底板，内底板和最靠近艉轴的非水密平台之间设有若干横向强结构件；横向强结构件上开设有第二开口部；艉轴穿设于第二开口部。本发明可以使艉轴轴承的检修工作无需进坞拆螺旋桨；使艉轴轴承的检修成本更低，维护更方便；油漆施工空间相对更大，空舱的低腐蚀环境使船舶结构的换新周期更长。
