The invention provides a rudder shaft supporting mechanism based on a crossed roller bearing. The rudder shaft supporting mechanism comprises a rocker arm rotating shaft, a first crossed roller assembly, a second crossed roller assembly, a first sealing ring, a second sealing ring, a mounting base, a bearing end cover and an axial locking component. According to the technical scheme, the rudder shaft supporting mechanism has the beneficial effects that (1) the two crossed roller assemblies are adopted as the supporting form of the rudder shaft supporting mechanism, large axial and radial loadscan be borne at the same time, the occupied space of the crossed roller assemblies in the axial direction and the radial direction is reduced, and thus the size and the weight are reduced; (2) sealing ring structures on the two sides are adopted, the control surface supporting mechanism can adapt to a severe environment, and reliable work can be guaranteed under the weather conditions of sand, dust, rain and the like; (3) the pre-tightening damping adjustment can be realized by adopting the axial locking component; (4) the internal clearance is small, the rotation precision is high, and the rigidity is high; and (5) the installation is simple, and the disassembly is convenient.
本发明提供了一种基于交叉滚子轴承的舵轴支撑机构，包括：摇臂转轴、第一交叉滚子组件、第二交叉滚子组件、第一密封圈、第二密封圈、安装座、轴承端盖和轴向锁紧部件。应用本发明的技术方案，具有如下有益效果：(1)通过采用两个交叉滚子组件作为舵轴支撑机构的支撑形式，能够同时承受较大的轴向和径向负载，减小了交叉滚子组件轴向和径向占用空间，从而降低了体积和重量；(2)通过采用两侧的密封圈结构，可使该舵面支撑机构能够适应恶劣环境，在沙尘淋雨等气候条件下能够保证可靠工作；(3)通过采用轴向锁紧部件能够实现预紧阻尼调节；(4)内部间隙较小、旋转精度高，同时具有高刚性；(5)安装简单和便于拆卸。
