摘要： The thrust load of an outer shaft (11) is received by a contra-rotating thrust bearing (40) provided in a boss (13a) of a front propeller (13) and transmitted to an inner shaft (12). The combined thrust load of the outer shaft (11) and the inner shaft (12) is received by an inner thrust bearing (41) provided on the bow side of the power transmission unit (20A) and transmitted to a ship body (2). The rotational force of an outer output shaft (24) is transmitted to the outer shaft (11) via a flexible joint (19) (gear coupling (19A)). Thus, the thrust load of the outer shaft (11) is transmitted to the ship body (2) only via the inner shaft (12) without being directly transmitted to the ship body (2), and the axial displacement and angular displacement are allowed by the gear coupling (19), so that it is possible to eliminate the influence of the change of hull deformation on the shaft center of the outer shaft (11).
摘要翻译：外轴（11）的推力载荷被设置在前螺旋桨（13）的凸台（13a）中并被传递到内轴（12）的对转推力轴承（40）所承受。设置在动力传递单元20A的船首一侧的内推力轴承41将外轴11和内轴12的合成推力载荷传递给船体2，。外输出轴（24）的旋转力经由挠性接头（19）（齿轮联轴节（19A））传递到外轴（11）。因此，外轴（11）的推力载荷仅通过内轴（12）传递到船体（2）而不直接传递到船体（2），并且允许轴向位移和角位移通过齿轮联轴节19，能够消除船体变形对外轴11的轴心的影响。

摘要： The object is to facilitate the installation of a contra-rotating propeller on a mother ship. Disclosed is a contra-rotating propeller unit in which a predetermined part on the rear side of an inner shaft (12) is supported by a contra-rotating rear bearing (36) provided in a boss (13a) of a front propeller (13), and which includes an inner fixing tool (50) detachably attached to a tip of an outer shaft (11) to temporarily support a predetermined part on the front side of the inner shaft (12), and a contra-rotating thrust bearing (40) provided in the boss (13a) of the front propeller (13) to receive the thrust load from the outer shaft (11) to transmit the thrust load to the inner shaft (12).
摘要翻译：目的是促进对转螺旋桨安装在母船。本发明公开了在其中的双反转螺旋桨组合件上的内轴的后侧的预定部分（12）由前螺旋桨的在一个凸台（13A）提供一种双反转后轴承（36）支承（13），并且其在内轴固定工具（50）包括可拆卸地附接至外轴（11）的前端到临时支撑在所述内轴（12）的前侧的预定部分，以及双反转推力轴承（40 ）提供在前面（13）的螺旋桨轴毂（13a）的从所述外轴（11）接收的推力载荷的推力负荷传递给内轴（12）。

摘要： Lubricant oil (45) serving as second lubricant oil is supplied into an outer intermediate shaft (11c) by a lubricant oil supply unit (50) and accumulated therein, and thereby the lubricant oil (45) is supplied to a contra-rotating front seal unit (37). Thus, by bringing the front side of the contra-rotating front seal unit (37) (seal ring (37b)) into a wet state by the lubricant oil (45), it is possible to reduce heat generation and it is possible to extend the life of the contra-rotating front seal unit (37).
摘要翻译：作为第二润滑油的润滑油（45）由润滑油供给单元（50）供给到外侧中间轴（11c）中并积存在其中，由此将润滑油（45）供给到反转正面密封件单位（37）。因此，通过使润滑油（45）将反转正面密封单元（37）（密封环（37b））的前侧置于湿润状态，可以减少发热，并且能够延长反转前密封单元（37）的寿命。
