船舶用舵
摘要：
本发明提供了一种船舶用舵，其能够降低由方向舵受到的舵力引起的在舵栓周边产生的弯曲应力，并且降低前进时的舵阻力。方向舵(13)的舵中间部(20)经由舵栓(16)而能够摆动地安装于舵托(12)。舵中间部(20)是将舵栓(16)固定于方向舵(13)的舵栓固定部(21)，或方向舵(13)的最短弦部(22)。船舶用舵(10)还具备舵球(14)，该舵球(14)位于螺旋桨(8)的轴心高度，且从舵托(12)或方向舵(13)沿法线方向鼓起。舵球(14)的至少一部分与舵中间部(20)一体地构成。
摘要（英）：

The invention discloses a rudder for a ship which can reduce a bending stress generated on a circumference of a pintle which is caused by a rudder under a rubber force and can reduce rudder resistancein a process of going forward. The middle portion (20) of the rudder (13) is installed in a rudder holder (12) in a swinging manner through a rudder bolt (16). The rudder middle portion (20) fixes the rudder bolt (16) on a rudder fixing part (21) of the rudder (13) or on a shortest ship rail of the rudder (13). The ship (10) also has a rudder ball (14) which is arranged in axial height of a screwpropeller and is bulged from the rudder holder (12) or the rudder (13) along a norm direction. At least part of the rudder ball (14) is integrated with the middle portion of the rudder.
