摘要： PURPOSE: To prevent damage of bearing and to eliminate single contact by supporting the propeller shaft by means of first bearing provided on the stern member and second bearing provided on a bearing supporting member on the surface of hull while fixing a propeller on a propeller shaft provided between both bearings.
CONSTITUTION: First bearing 11 is provided on a bearing boss 5 of stern member 4 while second bearing 12 is provided on a rudder horn 14 which is a projected section for supporting a rudder 13. The propeller shaft 2 is projected rearwarely from first bearing 11 where the rear end section is held by second bearing 12. Then a propeller 1 is fixed to a propeller shaft 2 between both bearings 11, 12. Since the propeller shaft 2 supports the heavy member or propeller 1, excessive load due to bending moment will never be applied on the bearings 11, 12.

摘要翻译：目的：为了防止轴承损坏，并通过在船尾构件上设置的第一轴承和设置在船体表面上的轴承支撑构件上的第二轴承支撑传动轴来消除单个接触，同时将螺旋桨固定在所提供的传动轴上两个轴承之间。构成：第一轴承11设置在船尾构件4的轴承凸台5上，而第二轴承12设置在作为用于支撑方向舵13的突出部分的舵角14上。传动轴2从第一轴承11向后可靠地突出，后端部由第二轴承12保持。然后，螺旋桨1在两个轴承11,12之间固定在传动轴2上。由于传动轴2支撑重部件或螺旋桨1，所以由于弯矩而产生的过大的载荷将永远不会施加在轴承11,12上。

摘要： PURPOSE:To enable to break ice and steam stably, by a method wherein an Archimedean screw on the port side of a bow part is made to be a left-handed screw, while an Archimedean screw on the starboard side is made to be a right- handed screw, and the screws are rotated in opposite directions to move broken ice pieces to the central side of a ship's hull. CONSTITUTION:The Archimedean screw 1a on the port side of the bow part is made to be a left-handed screw and is rotated counterclockwise, while the Archimedean screw 1b on the starboard side is made to be a right-handed screw and is rotated clockwise. when the ship's hull rides onto an ice plate 15, the directions of the forces exerted on the ice plate by screw blades are directions of the arrows R, L, respectively, so that the broken ice pieces 16 are moved to the central side of the ship's hull, and are removed astern. Accordingly, by causing the screws to so act as to collect the broken ice pieces toward the center of the ship's hull and remove them, the ice-breaking operation can be conducted smoothly in a stable condition.
摘要翻译：目的：为了能够稳定地破冰和蒸汽，通过将弓形部件的端口侧上的阿基米德螺钉制成左旋螺钉的方法，右舷侧的阿基米德螺丝被制成右侧旋转螺丝，并且螺钉沿相反方向旋转，以将破碎的冰块移动到船体的中心侧。构成：弓形部分的端口侧的阿基米德螺丝1a被制成左旋螺丝并逆时针旋转，而右舷侧的阿基米德螺丝1b被制成右旋螺丝并顺时针旋转。当船的船体骑在冰板15上时，由螺旋叶片施加在冰盘上的力的方向分别是箭头R，L的方向，使得破碎的冰块16移动到船体，并被拆除。因此，通过使螺钉起到向船体的中心收集破碎的冰块的作用，并将其去除，可以在稳定的状态下平稳地进行破冰作业。

摘要： PURPOSE:To achieve an ice breaker having excellent propulsion and turning performance, by fixing Archimedian serews in front and rear of the hull and discharging the ice broken by the bow screw through the stern screw. CONSTITUTION:Archimedian screws 4, 7 are fixed not only at the bow section 2 but also the stern section 5. Ice board is broken by the bow screw 4 then discharged effectively rearward by the stern screw 7 to prevent choking of broken ice thus to improve the propulsion and turning performance.

摘要： PURPOSE:To make the ice-breaking ability of a ship improvable ever so high while bringing the output down to some extent, by forming a screw drum diameter into a taper by degrees as going toward the end part. CONSTITUTION:Screws 1 are situated higher than a water lever 8 each in their front parts, while both screws 1 are disposed each in parallel wth a hull center line 7 but slant to the water level 8 and supported by each of bearings 10 and 11. The screws are driven independently at both gunwales by each of prime movers 12, cut into an ince floe 13 as self-propelling on the ice field, ride on the ice floe 13 and performs ice-breaking running on the ice floe 13. Ice breaking takes place with a cylindrical intermediate part 4 but its diameter is constant throughout the length unlike taper forms in both front and rear parts 5 and 6 so that stability in the hull at ice breaking is excellent, thus ice-breaking operation in constant trimness is now possible to be achieved.
摘要翻译：目的：为了使一艘船的破冰能力提高到一定程度上，使得输出转速降到一定程度以下，通过将螺杆滚筒的直径形成一个逐渐减小的锥度，朝向端部。构成：螺丝1位于其前部的每个水杆8上方，而两个螺钉1均布置在船体中心线7上，但是倾斜到水位8并由轴承10和11中的每一个支撑。螺旋桨由两个原动机12独立地驱动，每个原动机12切割成在冰场上自推进的絮凝物13，骑在冰橇13上，并在冰橇13上进行破冰运行。发生在圆柱形中间部分4上，但是其直径在整个长度上是恒定的，不同于前部和后部5和6中的锥形形状，使得在破冰时船体的稳定性是优异的，因此在恒定的修整中的破冰作用现在是有可能实现。
