The invention relates to a large-diameter rotary supporting device and a ship propeller thereof, the large-diameter rotary supporting device is used for the ship propeller, and the large-diameter rotary supporting device is characterized in that the rotary supporting device comprises a rotary supporting frame in a ring shape, and axial supporting bearings and radial supporting bearings are alternately arranged on the rotary supporting frame at intervals along the ring of the rotary supporting frame. The non-standardized rotary supporting device has the advantages that the non-standardized rotary supporting device is designed, the purpose of large-diameter rotary supporting is achieved in the mode that the integral rotary supporting frame and the small bearing are combined, and compared with an existing integral bearing, the small bearing is low in application cost and can be achieved through various bearing structures in the prior art; the small bearing is light in weight, easy to produce and manufacture and convenient to mount and replace; the small bearing is light, convenient and flexible to rotate and small in resistance during movement, the rotating speed requirement of a common propeller product can be met, the rotating speed of the large-diameter rotating supporting device is not limited, and the application range is wider.
一种大直径旋转支撑装置及其船舶推进器,所述的大直径旋转支撑装置用于船舶推进器,其特征在于:所述的旋转支撑装置包括有呈环圈状的旋转支撑架,该旋转支撑架沿其环圈间隔交替设置有轴向支撑轴承和径向支撑轴承。本发明的优点在于:设计了一种非标准化的旋转支撑装置,采用整体式旋转支撑架加上小轴承组合的方式来实现大直径旋转支撑的目的,相比较现有的整体式轴承,小轴承的应用成本低,可以采用现有技术中的各种轴承结构实现;小轴承重量轻,而且易于生产制造,安装和更换较为方便;小轴承的旋转轻便灵活、运动时阻力小,能够满足一般推进器产品的转速要求,使得大直径旋转支撑装置的转速不受限制,应用范围更加广泛。
