The invention belongs to the technical field of ship propulsion systems, and relates to a ship propulsion system shafting stern shaft sleeve structure. The invention further relates to a manufacturing method of the ship propulsion system shafting stern shaft sleeve structure. A rear bearing seat (6) is arranged on the outer ring of the rear epoxy part (5), a front bearing seat (7) is arranged on the outer ring of the front epoxy part (9), an outer sleeve (8) is arranged between the rear bearing seat (6) and the front bearing seat (7), a cavity part (16) is formed between the inner sleeve (4) and the outer sleeve (8), circulating lubricating oil is injected into the cavity part (16), and the outer sleeve (8) comprises a rear preassembled section (10), a front preassembled section (11), an embedded section (12) and two C-shaped pipe sealing section assemblies (13). According to the shafting stern shaft sleeve structure of the ship propulsion system, the machining procedure can be simplified, the construction period can be shortened, meanwhile, adverse effects and damage to the epoxy part are avoided, the overall performance is improved, and the service life is prolonged.

    本发明属于船舶推进系统技术领域的船舶推进系统轴系艉轴套结构,本发明还涉及一种船舶推进系统轴系艉轴套结构的制作方法。后环氧部(5)外圈设置后轴承座(6),前环氧部(9)外圈设置前轴承座(7),后轴承座(6)和前轴承座(7)之间设置外套管(8),内套管(4)和外套管(8)之间形成空腔部(16),空腔部(16)注入循环滑油,外套管(8)包括后预装段(10)、前预装段(11)、预埋段(12)、两个C字形的封管段组件(13)。本发明所述的船舶推进系统轴系艉轴套结构,能够简化加工工序,缩减施工周期,同时避免对环氧部造成不良影响和破坏,提升整体性能和使用寿命。
