The invention discloses a marine hollow large-wall-thickness rudder horn structure which comprises a rudder horn steel casting, a rudder horn front steel plate structure and a rudder horn upper end rear steel plate structure, and a rudder horn main body jointly formed by the rudder horn steel casting, the rudder horn front steel plate structure and the rudder horn upper end rear steel plate structure. The shape is matched with the rudder blade. According to the rudder horn steel casting, the interior of the rudder horn steel casting is arranged to be hollow, the weight of the rudder horn is reduced as much as possible while enough strength and rigidity are provided, good construction manufacturability is achieved, and the installation requirement of rudders for large ships can be met.
本发明公开了一种船用空心大壁厚挂舵臂结构,挂舵臂结构包括挂舵臂铸钢件、挂舵臂前部钢板结构和挂舵臂上端后部钢板结构,挂舵臂钢铸件、挂舵臂前部钢板结构和挂舵臂上端后部钢板结构共同构成的挂舵臂的主体,其外形与舵叶匹配。本发明通过将挂舵臂铸钢件内部设置为空心型式,在提供足够的强度和刚度的同时,尽可能的减少挂舵臂自身重量,具有良好的施工工艺性,可满足大型船舶用舵的安装要求。
