The invention provides an axially parallel split permanent magnet-water lubricated composite bearing, which belongs to the technical field of bearing design, is applied to a ship propulsion shafting, and comprises a magnetic force bearing module, a magnetic shaft sleeve, a magnet mounting base and a water lubricated bearing. The magnetic force bearing module and the water lubricated bearing are arranged in parallel in the axial direction of the stern shaft. The water-lubricated bearing is arranged on one side close to the propeller and is wholly soaked in a working medium; the magnetic shaft sleeve of a cylindrical structure is installed on a stern shaft, and a stern bearing is attracted under the action of a permanent magnet array in the magnetic force bearing module. And the magnet mounting base is used for supporting the magnetic force bearing module and regulating and controlling the magnetic force. According to the integral permanent magnet-water lubricated composite bearing, the permanent magnets and the water lubricated bearing in the integral permanent magnet-water lubricated composite bearing are structurally split, the mutual restriction of a magnetic force bearing module and a water lubricated bearing module in the aspects of space, size and performance can be effectively eliminated, and the use flexibility is enhanced; the bearing distribution of the shaft system can be optimized, and it is ensured that the tail shaft system has good dynamic stability.
本发明提供一种轴向并列的分体式永磁‑水润滑复合轴承,属于轴承设计技术领域,应用于船舶推进轴系,包括磁力承载模块、磁性轴套、磁体安装基座和水润滑轴承。磁力承载模块与水润滑轴承沿艉轴轴向并列布置;水润滑轴承布置在靠近螺旋桨一侧,整体浸泡于工作介质中;筒状结构的磁性轴套安装于艉轴上,在磁力承载模块中的永磁体阵列作用下使艉轴承受吸力;磁体安装基座用于支撑磁力承载模块,并对磁力进行调控。本发明将整体式永磁‑水润滑复合轴承中的永磁体与水润滑轴承进行结构上的拆分,能有效消除磁力承载模块和水润滑轴承模块在空间、尺寸、性能方面的相互制约,增强使用灵活性;可以优化轴系承载分布,确保艉轴轴系具有良好的动力学稳定性。
